Identifying solid waste.

(1) Purpose and applicability.
(a) The purpose of this section is to identify those materials that are and are not solid wastes.
(b)(i) The definition of solid waste contained in this section applies only to wastes that also are dangerous for purposes of the regulations implementing chapter 70.105 RCW. For example, it does not apply to materials (such as nondangerous scrap, paper, textiles, or rubber) that are not otherwise dangerous wastes and that are recycled.
(ii) This section identifies only some of the materials which are solid wastes and dangerous wastes under chapter 70.105 RCW. A material which is not defined as a solid waste in this section, or is not a dangerous waste identified or listed in this section, is still a solid waste and a dangerous waste for purposes of these sections if reason and authority exists under chapter 70.105 RCW and WAC 173-303-960. Within the constraints of chapter 70.105 RCW, this includes, but is not limited to, any material that: Is accumulated, used, reused, or handled in a manner that poses a threat to public health or the environment; or, due to the dangerous constituent(s) in it, when used or reused would pose a threat to public health or the environment.
(c) Certain materials are solid wastes but are excluded from the requirements of this chapter by WAC 173-303-071 and 173-303-073.
(2) The following terms are used and have the meanings as defined in WAC 173-303-040:
(a) Boiler
(b) By-product
(c) Incinerator
(d) Industrial furnace
(e) Reclaim
(f) Recover
(g) Recycle
(h) Used or reused (see reuse or use)
(i) Sludge
(j) Scrap metal
(k) Spent material
(l) Excluded scrap metal
(m) Processed scrap metal
(n) Home scrap metal
(o) Prompt scrap metal
(3) Definition of solid waste.
(a) A solid waste is any discarded material that is not excluded by WAC 173-303-017(2) or that is not excluded by variance granted under WAC 173-303-017(5).
(b) A discarded material is any material that is:
(i) Abandoned, as explained in subsection (4) of this section; or
(ii) Recycled, as explained in subsection (5) of this section; or
(iii) Considered inherently waste-like, as explained in subsection (6) of this section. Persons registering micronutrient or waste-derived fertilizers under chapter 15.54 RCW must submit information required by the department to indicate compliance with this chapter. The required minimum information is described in WAC 173-303-505; or
(iv) A military munition identified as a solid waste at WAC 173-303-578(2).
(4) Materials are solid waste if they are abandoned by being:
(a) Disposed of; or
(b) Burned or incinerated; or
(c) Accumulated, stored, or treated (but not recycled) before or in lieu of being abandoned by being disposed of, burned, or incinerated; or
(d) Sham recycled, as defined in subsection (8) of this section.
(5) Materials are solid wastes if they are recycled—or accumulated, stored, or treated before recycling—as specified in (a) through (d) of this subsection.
(a) Used in a manner constituting disposal. Materials noted with a "*" in column 1 of Table 1 are solid wastes when they are:
(i)(A) Applied to or placed on the land in a manner that constitutes disposal; or
(B) Used to produce products that are applied to or placed on the land or are otherwise contained in products that are applied to or placed on the land (in which cases the product itself remains a solid waste).
(ii) However, commercial chemical products listed in WAC 173-303-9903 or which exhibit any of the criteria or characteristics listed in WAC 173-303-090 or 173-303-100 are not solid wastes if they are applied to the land and that is their ordinary manner of use.
(b) Burning for energy recovery. Materials noted with a "*" in column 2 of Table 1 are solid wastes when they are:
(i) Burned to recover energy;
(ii) Used to produce a fuel or are otherwise contained in fuels (in which cases the fuel itself remains a solid waste).
However, commercial chemical products listed in WAC 173-303-9903 or which exhibit any of the criteria or characteristics listed in WAC 173-303-090 or 173-303-100 are not solid wastes if they are themselves fuels.
(c) Reclaimed. Materials noted with a "*" in column 3 of Table 1 are solid wastes when reclaimed.
(d)(i) Accumulated speculatively. Materials noted with a "*" in column 4 of Table 1 are solid wastes when accumulated speculatively.
(ii) A material is "accumulated speculatively" if it is accumulated before being recycled. A material is not accumulated speculatively, however, if the person accumulating it can show that the material is potentially recyclable and has a feasible means of being recycled; and that—during the calendar year (commencing on January 1)—the amount of material that is recycled, or transferred to a different site for recycling, equals at least seventy-five percent by weight or volume of the amount of that material accumulated at the beginning of the period. Materials must be placed in a storage unit with a label indicating the first date that the material began to be accumulated. If placing a label on the storage unit is not practical, the accumulation period must be documented through an inventory log or other appropriate method. In calculating the percentage of turnover, the seventy-five percent requirement is to be applied to each material of the same type (e.g., slags from a single smelting process) that is recycled in the same way (i.e., from which the same material is recovered or that is used in the same way). Materials accumulating in units that would be exempt from regulation under WAC 173-303-071 (3)(n) are not to be included in making the calculation. (Materials that are already defined as solid wastes also are not to be included in making the calculation.) Materials are no longer in this category once they are removed from accumulation for recycling, however.

(6) Inherently waste-like materials. The following materials are solid wastes when they are recycled in any manner:
(a) Dangerous Waste Nos. F020, F021 (unless used as an ingredient to make a product at the site of generation), F022, F023, F026, and F028.
(b) Secondary materials fed to a halogen acid furnace that exhibit a characteristic of a dangerous waste or are listed as a dangerous waste as defined in WAC 173-303-090 or 173-303-080 through 173-303-082, except for brominated material that meets the following criteria:
(i) The material must contain a bromine concentration of at least 45%; and
(ii) The material must contain less than a total of 1% of toxic organic compounds listed in WAC 173-303-9905; and
(iii) The material is processed continually on site in the halogen acid furnace via direct conveyance (hard piping).
(c) The department will use the following criteria to add wastes to (a) of this subsection:
(i)(A) The materials are ordinarily disposed of, burned, or incinerated; or
(B) The materials contain toxic constituents listed in WAC 173-303-9905 and these constituents are not ordinarily found in raw materials or products for which the materials substitute (or are found in raw materials or products in smaller concentrations) and are not used or reused during the recycling process; and
(ii) The material may pose a substantial hazard to human health or the environment when recycled.
(7) Documentation of claims that materials are not solid wastes or are conditionally exempt from regulation. Respondents in actions to enforce regulations implementing chapter 70.105 RCW who raise a claim that a certain material is not a solid waste, or is conditionally exempt from regulation, must demonstrate that there is a known market or disposition for the material, and that they meet the terms of the exclusion or exemption. In doing so, they must provide appropriate documentation (such as contracts showing that a second person uses the material as an ingredient in a production process) to demonstrate that the material is not a waste, or is exempt from regulation. In addition, owners or operators of facilities claiming that they actually are recycling materials must show that they have the necessary equipment to do so.
(8) Sham recycling. A material found to be sham recycled is considered discarded and a solid waste. Sham recycling is recycling that is not legitimate recycling as defined in WAC 173-303-019.

Recycling processes involving solid waste.

(1) The purpose of this section is to identify those materials that are and are not solid wastes when recycled. Certain materials, as described in subsection (2) of this section, would not typically be considered to involve waste management and are exempt from the requirements of this chapter. All recycling processes not exempted by subsection (2) of this section are subject to the recycling requirements of WAC 173-303-120.
(2) General categories of materials that are not solid waste when recycled.
(a) Except as provided in subsection (3) of this section, materials are not solid wastes when they can be shown to be recycled by being:
(i) Used or reused as ingredients in an industrial process to make a product provided the materials are not being reclaimed; or
(ii) Used or reused as effective substitutes for commercial products; or
(iii) Returned to the original process from which they are generated, without first being reclaimed or land disposed. The material must be returned as a substitute for feedstock materials. In cases where the original process to which the material is returned is a secondary process, the materials must be managed such that there is no placement on the land.
(b) Except as provided in subsection (3) of this section, the department has determined that the following materials when used as described are not solid wastes:
(i) Pulping liquors (e.g., black liquor) that are reclaimed in a pulping liquor recovery furnace and then reused in the pulping process;
(ii) Spent pickle liquor which is reused in wastewater treatment at a facility holding a national pollutant discharge elimination system (NPDES) permit, or which is being accumulated, stored, or treated before such reuse;
(iii) Spent sulfuric acid used to produce virgin sulfuric acid provided it is not accumulated speculatively as defined in WAC 173-303-016 (5)(d)(ii).
(3) The following materials are solid wastes, even if the recycling involves use, reuse, or return to the original process (as described in subsection (2)(a) of this section):
(a) Materials used in a manner constituting disposal, or used to produce products that are applied to the land; or
(b) Materials burned for energy recovery, used to produce a fuel, or contained in fuels; or
(c) Materials accumulated speculatively as defined in WAC 173-303-016 (5)(d)(ii); or
(d) Materials listed in WAC 173-303-016(6); or
(e) Any materials that the department determines are being accumulated, used, reused or handled in a manner that poses a threat to public health or the environment.
(4) Documentation of claims that materials are not solid wastes or are conditionally exempt from regulation. Respondents in actions to enforce regulations implementing chapter 70.105 RCW who raise a claim that a certain material is not a solid waste, or is conditionally exempt from regulation, must demonstrate that there is a known market or disposition for the material, and that they meet the terms of the exclusion or exemption. In doing so, they must provide appropriate documentation (such as contracts showing that a second person uses the material as an ingredient in a production process) to demonstrate that the material is not a waste, or is exempt from regulation. In addition, owners or operators of facilities claiming that they actually are recycling materials must show that they have the necessary equipment to do so.
(5) Variances from classification as a solid waste.
(a) In accordance with the standards and criteria in (b) of this subsection and the procedures in subsection (7) of this section, the department may determine on a case-by-case basis that the following recycled materials are not solid wastes:
(i) Materials that are accumulated speculatively without sufficient amounts being recycled (as defined in WAC 173-303-016 (5)(d)(ii));
(ii) Materials that are reclaimed and then reused within the original production process in which they were generated;
(iii) Materials that have been reclaimed but must be reclaimed further before the materials are completely recovered; and
(iv) State-only dangerous materials (not regulated as hazardous wastes (defined in WAC 173-303-040) by EPA) which serve as an effective substitute for a commercial product or raw material.
(b) Standards and criteria for variances from classification as a solid waste.
(i) The department may grant requests for a variance from classifying as a solid waste those materials that are accumulated speculatively without sufficient amounts being recycled if the applicant demonstrates that sufficient amounts of the material will be recycled or transferred for recycling in the following year. If a variance is granted, it is valid only for the following year, but can be renewed, on an annual basis, by filing a new application. The department's decision will be based on the following criteria:
(A) The manner in which the material is expected to be recycled, when the material is expected to be recycled, and whether this expected disposition is likely to occur (for example, because of past practice, market factors, the nature of the material, or contractual arrangements for recycling);
(B) The reason that the applicant has accumulated the material for one or more years without recycling seventy-five percent of the volume accumulated at the beginning of the year;
(C) The quantity of material already accumulated and the quantity expected to be generated and accumulated before the material is recycled;
(D) The extent to which the material is handled to minimize loss;
(E) Other relevant factors.
(ii) The department may grant requests for a variance from classifying as a solid waste those materials that are reclaimed and then reused as feedstock within the original production process in which the materials were generated if the reclamation operation is an essential part of the production process. This determination will be based on the following criteria:
(A) How economically viable the production process would be if it were to use virgin materials, rather than reclaimed materials;
(B) The extent to which the material is handled before reclamation to minimize loss;
(C) The time periods between generating the material and its reclamation, and between reclamation and return to the original primary production process;
(D) The location of the reclamation operation in relation to the production process;
(E) Whether the reclaimed material is used for the purpose for which it was originally produced when it is returned to the original process, and whether it is returned to the process in substantially its original form;
(F) Whether the person who generates the material also reclaims it;
(G) Other relevant factors.
(iii) The department may grant requests for a variance from classifying as a solid waste those hazardous secondary materials that have been partially reclaimed, but must be reclaimed further before recovery is completed, if the partial reclamation has produced a commodity-like material. A determination that a partially reclaimed hazardous secondary material for which the variance is sought is commodity-like will be based on whether the material is legitimately recycled as specified in WAC 173-303-019 and on whether all of the following decision criteria are satisfied:
(A) Whether the degree of partial reclamation the material has undergone is substantial as demonstrated by using a partial reclamation process other than the process that generated the dangerous waste;
(B) Whether the partially reclaimed material has sufficient economic value that it will be purchased for further reclamation;
(C) Whether the partially reclaimed material is a viable substitute for a product or intermediate produced from virgin or raw materials which is used in subsequent production steps;
(D) Whether there is a market for the partially reclaimed material as demonstrated by known customer(s) who are further reclaiming the material (e.g., records of sales and/or contracts and evidence of subsequent use, such as bills of lading);
(E) Whether the partially reclaimed material is handled to minimize loss; and
(F) Other relevant factors.
(iv) The department may grant requests for a variance from classifying as a solid waste those materials that serve as an effective substitute for a commercial product or raw material, when such material is not regulated as hazardous waste (defined in WAC 173-303-040) by EPA, if the materials are recycled in a manner such that they more closely resemble products or raw materials rather than wastes. This determination will be based on the following factors:
(A) The effectiveness of the material for the claimed use;
(B) The degree to which the material is like an analogous raw material or product;
(C) The extent to which the material is handled to minimize loss or escape to the environment;
(D) The extent to which an end market for the reclaimed material is guaranteed;
(E) The time period between generating the material and its recycling;
(F) Other factors as appropriate.
(6) Variance to be classified as a boiler.
In accordance with the standards and criteria in WAC 173-303-040 (definition of "boiler"), and the procedures in subsection (7) of this section, the department may determine on a case-by-case basis that certain enclosed devices using controlled flame combustion are boilers, even though they do not otherwise meet the definition of boiler contained in WAC 173-303-040, after considering the following criteria:
(a) The extent to which the unit has provisions for recovering and exporting thermal energy in the form of steam, heated fluids, or heated gases; and
(b) The extent to which the combustion chamber and energy recovery equipment are of integral design; and
(c) The efficiency of energy recovery, calculated in terms of the recovered energy compared with the thermal value of the fuel; and
(d) The extent to which exported energy is utilized; and
(e) The extent to which the device is in common and customary use as a "boiler" functioning primarily to produce steam, heated fluids, or heated gases; and
(f) Other factors, as appropriate.
(7) Procedures for variances from classification as a solid waste or to be classified as a boiler.
The department will use the following procedures in evaluating applications for variances from classification as a solid waste or applications to classify particular enclosed controlled flame combustion devices as boilers:
(a) The applicant must apply to the department for the variance. The application must address the relevant criteria contained in subsection (5)(b) or (6) of this section, as applicable.
(b) The department will evaluate the application and issue a draft public notice tentatively granting or denying the application. Notification of this tentative decision will be provided by newspaper advertisement and radio broadcast in the locality where the recycler is located. The department will accept comment on the tentative decision for thirty days, and may also hold a public hearing upon request or at its discretion. The department will issue a final decision after receipt of comments and after the hearing (if any).
(c) In the event of a change in circumstances that affect how a material meets the relevant criteria contained in subsection (5) or (6) of this section, as applicable, upon which a variance has been based, the applicant must send a description of the change in circumstances to the department. The department may issue a determination that the material continues to meet the relevant criteria of the variance or may require the facility to reapply for the variance.
(d) Variances shall be effective for a fixed term not to exceed ten years. No later than six months prior to the end of this term, facilities must reapply for a variance. If a facility reapplies for a variance within six months, the facility may continue to operate under an expired variance until receiving a decision on their reapplication from the department.
(e) Facilities receiving a variance must provide notification as required by subsection (8) of this section.
(8) Notification requirements for materials managed under variances from classification as a solid waste.
(a) Facilities managing hazardous secondary materials under WAC 173-303-017(5) must send a notification prior to operating under the regulatory provision and by March 1st of each even-numbered year thereafter to the department using ecology's Dangerous Waste Site Identification Form that includes the following information:
(i) The name, address, and EPA/state identification number (if applicable) of the facility;
(ii) The name and telephone number of a contact person;
(iii) The NAICS code of the facility;
(iv) The regulation under which the hazardous secondary materials will be managed;
(v) When the facility began or expects to begin managing the hazardous secondary materials in accordance with the regulation;
(vi) A list of hazardous secondary materials that will be managed according to the regulation (reported as the dangerous waste numbers that would apply if the hazardous secondary materials were managed as dangerous wastes);
(vii) The quantity of each hazardous secondary material to be managed annually; and
(viii) The certification (included in ecology's Dangerous Waste Site Identification Form) signed and dated by an authorized representative of the facility.
(b) If a facility managing hazardous secondary materials under this section has submitted a notification, but then subsequently stops managing those materials in accordance with the regulation(s) listed above, the facility must notify the department within thirty days using ecology's Dangerous Waste Site Identification Form. For purposes of this section, a facility has stopped managing hazardous secondary materials under this section if the facility no longer generates, manages, or reclaims materials under the regulation(s) above and does not expect to manage any amount of hazardous secondary materials under this section for at least one year.

Legitimacy criteria for recycling of hazardous secondary materials.

Recycling hazardous secondary materials for the purpose of exclusion or exemption from the dangerous waste regulations must be legitimate. Hazardous secondary material that is not legitimately recycled is discarded material and a solid waste. In determining if their recycling is legitimate, persons must address all the requirements of this section.
(1) Legitimate recycling must involve a hazardous secondary material that provides a useful contribution to the recycling process or to a product or intermediate of the recycling process. The hazardous secondary material provides a useful contribution if it:
(a) Contributes valuable ingredients to a product or intermediate; or
(b) Replaces a catalyst or carrier in the recycling process; or
(c) Is the source of a valuable constituent recovered in the recycling process; or
(d) Is recovered or regenerated by the recycling process; or
(e) Is used as an effective substitute for a commercial product.
(2) The recycling process must produce a valuable product or intermediate. The product or intermediate is valuable if it is:
(a) Used by the recycler or the generator as an effective substitute for a commercial product or as an ingredient or intermediate in an industrial process; or
(b) Sold to a third party.
(3) The generator, recycler, or third party must manage the hazardous secondary material as a valuable commodity when it is under their control. Where there is an analogous raw material, the hazardous secondary material must be managed, at a minimum, in a manner consistent with the management of the raw material or in an equally protective manner. Where there is no analogous raw material, the hazardous secondary material must be contained. Hazardous secondary materials that are released to the environment and are not recovered immediately are discarded.
(4) The product of the recycling process must be comparable to a legitimate product or intermediate:
(a) Where there is an analogous product or intermediate, the product of the recycling process is comparable to a legitimate product or intermediate if:
(i) The product of the recycling process does not exhibit a dangerous waste characteristic (as defined in WAC 173-303-090) or meet any dangerous waste criteria (as found in WAC 173-303-100) that analogous products do not exhibit; and
(ii) The concentrations of any dangerous constituents found in WAC 173-303-9905 that are in the product or intermediate are at levels that are comparable to or lower than those found in analogous products, or at levels that meet widely recognized commodity standards and specifications, in the case where the commodity standards and specifications include levels that specifically address those dangerous constituents.
(b) Where there is no analogous product, the product of the recycling process is comparable to a legitimate product or intermediate if:
(i) The product of the recycling process is a commodity that meets widely recognized commodity standards and specifications (e.g., commodity specification grades for common metals); or
(ii) The hazardous secondary materials being recycled are returned to the original process or processes from which they were generated to be reused (e.g., closed loop recycling).
(c) If the product of the recycling process has levels of dangerous constituents (found in WAC 173-303-9905) that are not comparable to or unable to be compared to a legitimate product or intermediate per (a) and (b) of this subsection, the recycling still may be shown to be legitimate if it meets the following specified requirements. The person performing the recycling must conduct the necessary assessment and prepare documentation showing why the recycling is, in fact, still legitimate.
(i) The recycling can be shown to be legitimate based on:
(A) Lack of exposure from toxics in the product;
(B) Lack of bioavailability of toxics in the product; or
(C) Other relevant considerations which show that the recycled product does not contain levels of dangerous constituents that pose a significant human health or environmental risk.
(ii) The documentation must include a certification statement that the recycling is legitimate and must be maintained on site for five years after the recycling operation has ceased.
(iii) The person performing the recycling must notify the department of this activity using ecology's site identification form.

Definitions.

When used in this chapter, the following terms have the meanings given below.
Note:
The list of defined terms in this section does not contain all defined terms used in chapter 173-303 WAC.
"Aboveground tank" means a device meeting the definition of "tank" in this section and that is situated in such a way that the entire surface area of the tank is completely above the plane of the adjacent surrounding surface and the entire surface area of the tank (including the tank bottom) is able to be visually inspected.
"Accumulation" refers to the definition of "storage."
"Active life" of a facility means the period from the initial receipt of dangerous waste at the facility until the department receives certification of final closure.
"Active portion" means that portion of a facility which is not a closed portion, and where dangerous waste recycling, reuse, reclamation, transfer, treatment, storage or disposal operations are being or have been conducted after:
The effective date of the waste's designation by 40 C.F.R. Part 261; and
March 10, 1982, for wastes designated only by this chapter and not designated by 40 C.F.R. Part 261. (See also "closed portion" and "inactive portion.")
"Active range" means a military range that is currently in service and is being regularly used for range activities.
"Acute hazardous waste" means dangerous waste sources (listed in WAC 173-303-9904) F020, F021, F022, F023, F026, or F027, and discarded chemical products (listed in WAC 173-303-9903) that are identified with a dangerous waste number beginning with a "P", including those wastes mixed with source, special nuclear, or by-product material subject to the Atomic Energy Act of 1954. The abbreviation "AHW" will be used in this chapter to refer to those dangerous and mixed wastes which are acute hazardous wastes. Note - The terms acute and acutely are used interchangeably.
"Airbag waste" means any dangerous waste airbag modules or dangerous waste airbag inflators.
"Airbag waste collection facility" means any facility that receives airbag waste from airbag handlers subject to regulation under WAC 173-303-071 (3)(tt), and accumulates the waste for more than ten days.
"Airbag waste handler" means any person, by site, who generates airbag waste that is subject to the regulations under this chapter.
"Ampule" means an airtight vial made of glass, plastic, metal, or any combination of these materials.
"Ancillary equipment" means any device including, but not limited to, such devices as piping, fittings, flanges, valves, and pumps, that is used to distribute, meter, or control the flow of dangerous waste from its point of generation to a storage or treatment tank(s), between dangerous waste storage and treatment tanks to a point of disposal on site, or to a point of shipment for disposal off site.
"Aquifer" means a geologic formation, group of formations, or part of a formation capable of yielding a significant amount of groundwater to wells or springs.
"Authorized representative" means the person responsible for the overall operation of a generator site, facility, or an operational unit (e.g., plant manager, superintendent or an employee of the company of equivalent responsibility).
"Batch" means any waste which is generated less frequently than once a month.
"Battery" means a device consisting of one or more electrically connected electrochemical cells which is designed to receive, store, and deliver electric energy. An electrochemical cell is a system consisting of an anode, cathode, and an electrolyte, plus such connections (electrical and mechanical) as may be needed to allow the cell to deliver or receive electrical energy. The term battery also includes an intact, unbroken battery from which the electrolyte has been removed.
"Berm" means the shoulder of a dike.
"Boiler" means an enclosed device using controlled flame combustion and having the following characteristics:
The unit must have physical provisions for recovering and exporting thermal energy in the form of steam, heated fluids, or heated gases; and
The unit's combustion chamber and primary energy recovery section(s) must be of integral design. To be of integral design, the combustion chamber and the primary energy recovery section(s) (such as waterwalls and superheaters) must be physically formed into one manufactured or assembled unit. A unit in which the combustion chamber and the primary energy recovery section(s) are joined only by ducts or connections carrying flue gas is not integrally designed; however, secondary energy recovery equipment (such as economizers or air preheaters) need not be physically formed into the same unit as the combustion chamber and the primary energy recovery section. The following units are not precluded from being boilers solely because they are not of integral design: Process heaters (units that transfer energy directly to a process stream), and fluidized bed combustion units; and
While in operation, the unit must maintain a thermal energy recovery efficiency of at least sixty percent, calculated in terms of the recovered energy compared with the thermal value of the fuel; and
The unit must export and utilize at least seventy-five percent of the recovered energy, calculated on an annual basis. In this calculation, no credit will be given for recovered heat used internally in the same unit. (Examples of internal use are the preheating of fuel or combustion air, and the driving of induced or forced draft fans or feedwater pumps); or
The unit is one which the department has determined, on a case-by-case basis, to be a boiler, after considering the standards in WAC 173-303-017(6).
"By-product" means a material that is not one of the primary products of a production process and is not solely or separately produced by the production process. Examples are process residues such as slags or distillation column bottoms. The term does not include a coproduct that is produced for the general public's use and is ordinarily used in the form it is produced by the process.
"Carbon regeneration unit" means any enclosed thermal treatment device used to regenerate spent activated carbon.
"Carcinogenic" means a material known to contain a substance which has sufficient or limited evidence as a human or animal carcinogen as listed in both IARC and either IRIS or HEAST.
"Cathode ray tube" or "CRT" means a vacuum tube, composed primarily of glass, which is the visual or video display component of an electronic device. A used, intact CRT means a CRT whose vacuum has not been released. A used, broken CRT means glass removed from its housing or casing whose vacuum has been released.
"Central accumulation area" means any on-site dangerous waste accumulation area subject to either WAC 173-303-200 (large quantity generators) or WAC 173-303-172 (medium quantity generators). A central accumulation area at an eligible academic entity that chooses to operate under WAC 173-303-235 must also comply with WAC 173-303-235(12) when accumulating unwanted material and/or dangerous waste.
"Chemical agents and chemical munitions" are defined as in 50 U.S.C. section 1521 (j)(1).
"Cleanup-only facility" means a site, including any contiguous property owned or under the control of the owner or operator of the site, where the owner or operator is or will be treating, storing, or disposing of remediation waste, including dangerous remediation waste, and is not, has not and will not be treating, storing or disposing of dangerous waste that is not remediation waste. A cleanup-only facility is not a "facility" for purposes of corrective action under WAC 173-303-646.
"Closed portion" means that portion of a facility which an owner or operator has closed, in accordance with the approved facility closure plan and all applicable closure requirements.
"Closure" means:
• The requirements placed upon all recycling, used oil, and TSD facilities, plus some generators, and some transporters to ensure that all such facilities are closed in an acceptable manner (see also "post-closure"); and
• Once taken out of service, the proper cleaning up and/or decontaminating of a dangerous waste management unit or a recycling unit and any areas affected by releases from the unit.
"College/university" see WAC 173-303-235.
"Commercial chemical product or manufacturing chemical intermediate" refers to a chemical substance which is manufactured or formulated for commercial or manufacturing use which consists of the commercially pure grade of the chemical, any technical grades of the chemical that are produced or marketed, and all formulations in which the chemical is the sole active ingredient.
"Commercial fertilizer" means any substance containing one or more recognized plant nutrients and which is used for its plant nutrient content and/or which is designated for use or claimed to have value in promoting plant growth, and includes, but is not limited to, limes, gypsum, and manipulated animal manures and vegetable compost. The commercial fertilizer must be registered with the state or local agency regulating the fertilizer in the locale in which the fertilizer is being sold or applied.
"Compliance procedure" means any proceedings instituted pursuant to the Hazardous Waste Management Act, chapter 70.105 RCW, and Hazardous waste fees, chapter 70.105A RCW, or regulations issued under authority of state law, which seeks to require compliance, or which is in the nature of an enforcement action or an action to cure a violation. A compliance procedure includes a notice of intention to terminate a permit pursuant to WAC 173-303-830(5), or an application in the state superior court for appropriate relief under the Hazardous Waste Management Act. A compliance procedure is considered to be pending from the time a notice of violation or of intent to terminate a permit is issued or judicial proceedings are begun, until the department notifies the owner or operator in writing that the violation has been corrected or that the procedure has been withdrawn or discontinued.
"Component" means either the tank or ancillary equipment of a tank system.

"Dangerous waste constituents" means those constituents listed in WAC 173-303-9905 and any other constituents that have caused a waste to be a dangerous waste under this chapter.
"Dangerous waste management unit" is a contiguous area of land on or in which dangerous waste is placed, or the largest area in which there is a significant likelihood of mixing dangerous waste constituents in the same area. Examples of dangerous waste management units include a surface impoundment, a waste pile, a land treatment area, a landfill cell, an incinerator, a tank and its associated piping and underlying containment system and a container storage area. A container alone does not constitute a unit; the unit includes containers and the land or pad upon which they are placed.
"Dangerous wastes" means those solid wastes designated in WAC 173-303-070 through 173-303-100 as dangerous, or extremely hazardous or mixed waste. As used in this chapter, the words "dangerous waste" will refer to the full universe of wastes regulated by this chapter.

Notification, identification numbers, and annual reports.

(1) Any person who generates, transports, offers for transport, or transfers a dangerous waste, or who owns or operates a dangerous waste TSD facility or a recycling facility must have a current EPA/state identification number (EPA/state ID#). An EPA/state ID# is issued to TSD facilities, recycling facilities, and generators by site. A state registration number is assigned to transfer facilities by site. Any person who offers a dangerous waste to a transporter or to a dangerous waste TSD facility or recycling facility that does not have an EPA/state ID#, or whose EPA/state ID# has been canceled or withdrawn, is in violation of this regulation.
(2) Every person who must have an EPA/state ID#, and who has not already received their ID#, must notify the department by obtaining and completing a Washington State Dangerous Waste Site Identification Form according to the instructions on the form and submitting the completed form to the department. Any person already assigned an EPA/state ID# must notify the department of any changes to their company's name, mailing address, ownership, physical location, or type of dangerous waste activity, by submitting a revised form. A revised form must be submitted prior to adding or dropping any of the following activities: Permitted treating, storing and/or disposing, immediate recycling, transporting, permit by rule, and/or treatment by generator. Any change in site location will require the issuance of a new EPA/state ID# for waste generation and management facilities. An existing EPA/state ID# cannot be transferred to a new company location. A company that has obtained an ID# as a "transporter only" (e.g., those who do not store or generate waste on site) can move to a new location and continue to use the same ID#. A revised Dangerous Waste Site Identification Form must be submitted to the department. A Dangerous Waste Site Identification Form and instructions for its completion may be obtained by contacting the department.
(3) Any person with an EPA/state ID# may request that their ID# be withdrawn if they will no longer be handling dangerous waste at the site the ID# has been assigned to. Any person whose ID# has been withdrawn must notify the department before they use the ID# at any later date. Notification must be in writing, except in the case of emergencies (e.g., fires, spills, etc.) such notification may be provided by telephone first, and followed within one week by a written notification. Withdrawal will only be granted when all applicable requirements of this chapter and chapter 173-305 WAC have been met.
(4) Any person with an EPA/state ID# may request that their ID# be withdrawn if they will no longer occupy the site. Notification must be in writing. An EPA/state ID# will be considered withdrawn only after all applicable requirements of this chapter and chapter 173-305 WAC have been met.
(5) Any person with a current EPA/state ID# must submit an annual report as required by WAC 173-303-170 (2)(a)(i), 173-303-220, 173-303-120, 173-303-390, and 173-303-515. Any person who has withdrawn their ID# must submit an annual report up to the effective date of withdrawal. The generator should write the effective date on the Dangerous Waste Site Identification Form for the withdrawal; it is the date by which all regulated waste activities (generation, transportation, and management) have ceased at the site.
(6) A recognized trader must not arrange for import or export of dangerous waste without having received an EPA/state ID# from the department.

Designation of dangerous waste.

(1) Purpose and applicability.
(a) This section describes the procedures for determining whether or not a solid waste is DW or EHW.
(b) The procedures in this section are applicable to any person who generates, or discovers on their site, a solid waste, as defined in WAC 173-303-016 (including recyclable materials) that is not exempted or excluded by this chapter, or by the department, or who is directed to or must further designate waste by subsection (4) or (5) of this section. Any person who generates or discovers a solid waste on their site must make an accurate determination if that waste is a dangerous waste in order to ensure wastes are properly managed according to applicable dangerous waste regulations. A dangerous waste determination is made by following the designation procedures set forth in subsection (3) of this section. Any person who determines by these procedures that their waste is designated DW or EHW is subject to all applicable requirements of this chapter.
(2)(a) Except as provided in (c) of this subsection, once a material has been determined to be a dangerous waste, then any solid waste generated from the recycling, treatment, storage, or disposal of that dangerous waste is a dangerous waste unless and until:
(i) The generator has been able to accurately describe the variability or uniformity of the waste over time, and has been able to obtain demonstration samples which are representative of the waste's variability or uniformity; and
(ii)(A) It does not exhibit any of the characteristics of WAC 173-303-090; however, wastes that exhibit a characteristic at the point of generation may still be subject to the requirements of WAC 173-303-140 (2)(a), even if they no longer exhibit a characteristic at the point of land disposal; and
(B) If it was a listed waste under WAC 173-303-080 through 173-303-083, it also has been exempted pursuant to WAC 173-303-910(3); or
(iii) If originally designated only through WAC 173-303-100, it does not meet any of the criteria of WAC 173-303-100. Such solid waste will include, but not be limited to, any sludge, spill residue, ash emission control dust, leachate, or precipitation runoff. Precipitation runoff will not be considered a dangerous waste if it can be shown that the runoff has not been contaminated with the dangerous waste, or that the runoff is adequately addressed under existing state laws (e.g., chapter 90.48 RCW), or that the runoff does not exhibit any of the criteria or characteristics described in WAC 173-303-100.
(b) Materials that are reclaimed from solid wastes and that are used beneficially (as provided in WAC 173-303-016 and 173-303-017) are not solid wastes and hence are not dangerous wastes under this section unless the reclaimed material is burned for energy recovery or used in a manner constituting disposal.
(c)(i) A dangerous waste that is listed in WAC 173-303-081(1) or 173-303-082(1) solely because it exhibits one or more characteristics of ignitability as defined under WAC 173-303-090(5), corrosivity as defined under WAC 173-303-090(6), or reactivity as defined under WAC 173-303-090(7) is not a dangerous waste, if the waste no longer exhibits any characteristic of dangerous waste identified in WAC 173-303-090 or any criteria identified in WAC 173-303-100.
(ii) The exclusion described in (c)(i) of this subsection also pertains to:
(A) Any solid waste generated from treating, storing, or disposing of a dangerous waste listed in WAC 173-303-081(1) or 173-303-082(1) solely because it exhibits the characteristics of ignitability, corrosivity, or reactivity as regulated under (a) and (b) of this section.
(B) Wastes excluded under this section are subject to 40 C.F.R. Part 268, which is incorporated by reference at WAC 173-303-140 (2)(a) (as applicable), even if they no longer exhibit a characteristic at the point of land disposal.
(3) Designation procedures.
(a) The dangerous waste designation for each solid waste must begin promptly at the point of waste generation or upon the discovery of a solid waste on their site. This must be done before any dilution, mixing, or other alteration of the waste occurs, and at any time in the course of its management that it has, or may have, changed its properties as a result of exposure to the environment or other factors that may change the properties of the waste such that the solid waste or dangerous waste classification of the waste may change.
(b) A person must determine whether the solid waste is excluded from regulation under WAC 173-303-071.
(c) A person must check each section, in the order set forth in (d) of this subsection, to determine whether the waste is designated as a dangerous waste. When the waste is determined to be a dangerous waste following the steps in (d)(i) through (iii) of this subsection, further designation is not required except as required by subsection (4) or (5) of this section. If a person has checked the waste against each section and the waste is not designated, then the waste is not subject to the requirements of this chapter 173-303 WAC.
Any person who wishes to seek an exemption for a waste which has been designated DW or EHW must comply with the requirements of WAC 173-303-072.
(d) To determine whether or not a solid waste is designated as a dangerous waste a person must:
(i) First, determine if the waste is a listed discarded chemical product, WAC 173-303-081;
(ii) Second, determine if the waste is a listed dangerous waste source, WAC 173-303-082;
(iii) Third, determine if the waste also exhibits one or more dangerous waste characteristics, WAC 173-303-090; and
(iv) Fourth, if the waste is not listed in WAC 173-303-081 or 173-303-082, and does not exhibit a characteristic in WAC 173-303-090, determine if the waste meets one or more dangerous waste criteria, WAC 173-303-100.
(e) For the purpose of determining if a solid waste is a dangerous waste as identified in WAC 173-303-080 through 173-303-100, a person must either:
(i) Test the waste according to the methods, or an approved equivalent method, set forth in WAC 173-303-110; or
(ii) Apply knowledge of the waste in light of the materials or the process used, when:
(A) Such knowledge can be demonstrated to be sufficient for determining whether or not it designated and/or designated accurately; and
(B) All data and records supporting this determination in accordance with WAC 173-303-210(3) are retained on-site; and
(C) When available knowledge is inadequate or absent to make an accurate designation, the generator must test the waste according to the methods, or an approved equivalent method, set forth in WAC 173-303-110.
(f) Persons testing their waste must obtain a representative sample of the waste for the testing set forth in WAC 173-303-110.
(g) Test results from properly performed test methods specified in WAC 173-303-090 and 173-303-100 are definitive for determining the designation and regulatory status of the waste.
(4) Testing required. Notwithstanding any other provisions of this chapter, the department may require any person to test a waste according to the methods, or an approved equivalent method, set forth in WAC 173-303-110 to determine whether or not the waste is designated under the dangerous waste lists, characteristics, or criteria, WAC 173-303-080 through 173-303-100. Such testing may be required if the department has reason to believe that the waste would be designated DW or EHW by the dangerous waste lists, characteristics, or criteria, or if the department has reason to believe that the waste is designated improperly (e.g., the waste has been designated DW but should actually be designated EHW). If a person, pursuant to the requirements of this subsection, determines that the waste is a dangerous waste or that its designation must be changed, then they are subject to the applicable requirements of this chapter 173-303 WAC. The department will base a requirement to test a waste on evidence that includes, but is not limited to:
(a) Test information indicating that the person's waste may be DW or EHW;
(b) Evidence that the person's waste is very similar to another persons' already designated DW or EHW;
(c) Evidence that the persons' waste has historically been a DW or EHW;
(d) Evidence or information about a person's manufacturing materials or processes which indicate that the wastes may be DW or EHW; or
(e) Evidence that the knowledge or test results a person has regarding a waste is not sufficient for determining whether or not it designated and/or designated accurately.
(5) Additional designation required. A generator must manage dangerous waste under the most stringent management standards that apply. The following subsections describe how waste that has been designated as DW under the dangerous waste lists, WAC 173-303-080 through 173-303-082, or characteristics, WAC 173-303-090, or in the case of (c) of this subsection, under the lists, characteristics, or criteria, must be further designated under the dangerous waste criteria, WAC 173-303-100. This further designation under the criteria is necessary because it may change how the waste must be managed. Additional designation is required when:
(a) The waste is designated as DW with a QEL of 220 pounds and the generator otherwise qualifies as a small quantity generator. In this case, a generator must determine if their DW is also designated as a toxic EHW, WAC 173-303-100, with a QEL of 2.2 pounds; or
(b) The waste is designated as DW and the waste is to be discharged to a POTW operating under WAC 173-303-802(4) (Permits by rule). In this case, a generator must determine if the waste is also an EHW under WAC 173-303-100; or
(c) The waste is designated as a state-only DW and the waste is to be:
(i) Burned for energy recovery, as used oil, under the provisions of WAC 173-303-515; or
(ii) Land disposed within the state. In this case, a generator must determine if the waste is also an EHW under WAC 173-303-100.
(6) Dangerous waste numbers. When a person is designating, reporting, or keeping records on a dangerous waste, they must use all the dangerous waste numbers which they know are assignable to the waste from the dangerous waste lists, characteristics, or criteria. For example, if the waste is ignitable and contains more than 5 mg/l leachable lead when tested for the toxicity characteristic, they must use the dangerous waste numbers of D001 and D008. This will not be construed as requiring a person to designate their waste beyond those designation requirements set forth in subsections (2) through (5) of this section.

Excluded categories of waste.

(1) Purpose. Certain categories of waste have been excluded from many of the requirements of chapter 173-303 WAC because they generally are not dangerous waste, are regulated under other state and federal programs, or are recycled in ways which do not threaten public health or the environment. WAC 173-303-071 describes these excluded categories of waste.
(2) Excluding wastes. Any persons who generate a common class of wastes and who seek to categorically exclude such class of wastes from the requirements of this chapter must comply with the applicable requirements of WAC 173-303-072. No waste class will be excluded if any of the wastes in the class are regulated as hazardous waste under 40 C.F.R. Part 261.
(3) Exclusions. The following categories of waste are excluded from the requirements of chapter 173-303 WAC, except for WAC 173-303-050, 173-303-145, and 173-303-960, and as otherwise specified:
(a)(i) Domestic sewage; and
(ii) Any mixture of domestic sewage and other wastes that passes through a sewer system to a publicly owned treatment works (POTW) for treatment, except as prohibited by WAC 173-303-555(6), provided:
(A) The generator or owner/operator has obtained a state waste discharge permit issued by the department, a temporary permit obtained pursuant to RCW 90.48.200, or pretreatment permit (or written discharge authorization) from a local sewage utility delegated pretreatment program responsibilities pursuant to RCW 90.48.165;
(B) The waste discharge is specifically authorized in a state waste discharge permit, pretreatment permit or written discharge authorization, or in the case of a temporary permit the waste is accurately described in the permit application;
(C) The waste discharge is not prohibited under 40 C.F.R. Part 403.5; and
(D) The waste prior to mixing with domestic sewage must not exhibit dangerous waste characteristics for ignitability, corrosivity, reactivity, or toxicity as defined in WAC 173-303-090, and must not meet the dangerous waste criteria for toxic dangerous waste or persistent dangerous waste under WAC 173-303-100, unless the waste is treatable in the publicly owned treatment works (POTW) where it will be received. This exclusion does not apply to the generation, treatment, storage, recycling, or other management of dangerous wastes prior to discharge into the sanitary sewage system;
(b) Industrial wastewater discharges that are point-source discharges subject to regulation under Section 402 of the Clean Water Act. This exclusion does not apply to the collection, storage, or treatment of industrial waste-waters prior to discharge, nor to sludges that are generated during industrial wastewater treatment. Owners or operators of certain wastewater treatment facilities managing dangerous wastes may qualify for a permit-by-rule pursuant to WAC 173-303-802(5);
(c) Household wastes, including household waste that has been collected, transported, stored, or disposed. Wastes that are residues from or are generated by the management of household wastes (e.g., leachate, ash from burning of refuse-derived fuel) are not excluded by this provision. "Household wastes" means any waste material (including, but not limited to, garbage, trash, and sanitary wastes in septic tanks) derived from households (including single and multiple residences, hotels and motels, bunkhouses, ranger stations, crew quarters, campgrounds, picnic grounds, and day-use recreation areas). A resource recovery facility managing municipal solid waste will not be deemed to be treating, storing, disposing of, or otherwise managing dangerous wastes for the purposes of regulation under this chapter, if such facility:
(i) Receives and burns only:
(A) Household waste (from single and multiple dwellings, hotels, motels, and other residential sources); and
(B) Solid waste from commercial or industrial sources that does not contain dangerous waste; and
(ii) Such facility does not accept dangerous wastes and the owner or operator of such facility has established contractual requirements or other appropriate notification or inspection procedures to assure that dangerous wastes are not received at or burned in such facility;
(d) Agricultural crops and animal manures which are returned to the soil as fertilizers;
(e) Asphaltic materials designated only for the presence of PAHs by WAC 173-303-100(6). For the purposes of this exclusion, asphaltic materials means materials that have been used for structural and construction purposes (e.g., roads, dikes, paving) that were produced from mixtures of oil and sand, gravel, ash or similar substances;
(f) Roofing tars and shingles, except that these wastes are not excluded if mixed with wastes listed in WAC 173-303-081 or 173-303-082, or if they exhibit any of the characteristics specified in WAC 173-303-090;
(g) Treated wood waste and wood products including:
(i) Arsenical-treated wood that fails the test for the toxicity characteristic of WAC 173-303-090(8) (dangerous waste numbers D004 through D017 only) or that fails any state criteria, if the waste is generated by persons who utilize the arsenical-treated wood for the materials' intended end use. Intended end use means the wood products must have been used in typical treated wood applications (for example, fence posts, decking, poles, and timbers).
(ii) Wood treated with other preservatives provided such treated wood and wood waste (for example, sawdust and shavings) are, within one hundred eighty days after becoming waste:
(A) Disposed of at a landfill that is permitted in accordance with chapter 173-350 WAC, Solid waste handling standards, or chapter 173-351 WAC, criteria for municipal solid waste landfills, and provided that such wood is neither a listed waste under WAC 173-303-9903 and 173-303-9904 nor a TCLP waste under WAC 173-303-090(8); or
(B) Sent to a facility that will legitimately treat or recycle the treated wood waste, and manage any residue in accordance with that state's dangerous waste regulations; or
(C) Sent off-site to a permitted TSD facility or placed in an on-site facility which is permitted by the department under WAC 173-303-800 through 173-303-845. In addition, creosote-treated wood is excluded when burned for energy recovery in an industrial furnace or boiler that has an order of approval issued pursuant to RCW 70.94.152 by ecology or a local air pollution control authority to burn creosote treated wood.
(h) Irrigation return flows;
(i) (Reserved);
(j) Mining overburden returned to the mining site;
(k) Polychlorinated biphenyl (PCB) wastes:

The notification and certification that is placed in the generator's or treater's files must be updated if the process or operation generating the waste changes and/or if the subtitle D unit receiving the waste changes. However, the generator or treater need only notify the department on an annual basis if such changes occur. Such notification and certification should be sent to the department by the end of the calendar year, but no later than December 31. The notification must include the following information: The name and address of the subtitle D unit receiving the waste shipments; the dangerous waste number(s) and treatability group(s) at the initial point of generation; and, the treatment standards applicable to the waste at the initial point of generation. The certification must be signed by an authorized representative and must state as follows: "I certify under penalty of law that the generic exclusion levels for all constituents have been met without impermissible dilution and that no characteristic of dangerous waste is exhibited. I am aware that there are significant penalties for submitting a false certification, including the possibility of fine and imprisonment." These wastes are not excluded if they exhibit one or more of the dangerous waste characteristics (WAC 173-303-090) or criteria (WAC 173-303-100).

Materials inserted into thermal cracking units are excluded under this paragraph: Provided that the coke product also does not exhibit a characteristic of hazardous waste. Oil-bearing hazardous secondary materials may be inserted into the same petroleum refinery where they are generated, or sent directly to another petroleum refinery, and still be excluded under this provision. Except as provided in (cc)(ii) of this subsection, oil-bearing hazardous secondary materials generated elsewhere in the petroleum industry (that is, from sources other than petroleum refineries) are not excluded under this section. Residuals generated from processing or recycling materials excluded under this paragraph, where such materials as generated would have otherwise met a listing under WAC 173-303-081 and 173-303-082, are designated as F037 listed wastes when disposed of or intended for disposal.
(ii) Recovered oil that is recycled in the same manner and with the same conditions as described in (cc)(i) of this subsection. Recovered oil is oil that has been reclaimed from secondary materials (including wastewater) generated from normal petroleum industry practices, including refining, exploration and production, bulk storage, and transportation incident thereto (NAICS codes 211111, 211112, 213111, 213112, 541360, 237120, 238910, 324110, 486110, 486910, 486210, 221210, 488210, 488999, 424710, 454311, 454312, 424720, 425120). Recovered oil does not include oil-bearing hazardous wastes listed in WAC 173-303-081 and 173-303-082; however, oil recovered from such wastes may be considered recovered oil. Recovered oil does not include used oil as defined in WAC 173-303-040.

Procedures and bases for exempting and excluding wastes.

(1) Purpose and applicability.
(a) The purpose of this section is to describe the procedures that will be followed by generators and the department when wastes are considered for exemption or exclusion from the requirements of this chapter. Any person(s) whose waste is exempted or excluded will not be subject to the requirements of this chapter unless the department revokes the exemption or exclusion.
(b) Any person seeking a waste exemption must submit a petition to the department according to the procedures of WAC 173-303-910(3). A petition for exemption will be assessed against the applicable bases for exemption described in subsections (3) and (4) of this section.
(c) Any persons seeking to categorically exclude a class of wastes must submit a petition to the department according to the procedures of WAC 173-303-910(4). A petition for exclusion will be assessed against the applicable bases for exclusion described in subsection (6) of this section.
(2) Department procedures. When considering, granting, or denying a petition for exemption or exclusion, the department will follow the appropriate procedures described in WAC 173-303-910(1).
(3) Bases for exempting wastes. To successfully petition the department to exempt a waste, the petitioner must demonstrate to the satisfaction of the department that:
(a) He has been able to accurately describe the variability or uniformity of his waste over time, and has been able to obtain demonstration samples which are representative of his waste's variability or uniformity; and, either
(b) The representative demonstration samples of his waste are not designated DW or EHW by the dangerous waste criteria, WAC 173-303-100; or
(c) It can be shown, from information developed by the petitioner through consultation with the department, that his waste does not otherwise pose a threat to public health or the environment. However, this basis for exemption is not applicable to wastes that exhibit any of the characteristics specified in WAC 173-303-090, except 173-303-090 (6)(a)(iii).
(4) Additional bases for exempting listed wastes. In addition to the demonstrations required by subsections (3)(a) and (b) of this section, for wastes listed in WAC 173-303-081 or 173-303-082 the petitioner must also demonstrate to the satisfaction of the department that his waste is not capable of posing a substantial present or potential threat to public health or the environment when improperly treated, stored, transported, disposed of or otherwise managed. The following factors will be considered by the department when assessing such a demonstration:
(a) Whether or not the listed waste contains the constituent or constituents which caused it to be listed. (For the purposes of this subsection, the constituents referred to will include any of the dangerous waste constituents listed in WAC 173-303-9905);
(b) The nature of the threat posed by the waste constituent(s);
(c) The concentration of the constituent(s) in the waste;
(d) The potential of the constituent(s) or any degradation product of the constituent(s) to migrate from the waste into the environment under the types of improper management considered in (h) of this subsection;
(e) The persistence of the constituent(s) or any degradation product of the constituent(s);
(f) The potential for the constituent(s) or any degradation product of the constituent(s) to degrade into nonharmful constituents and the rate of degradation;
(g) The degree to which the constituent(s) or degradation product of the constituent(s) bioaccumulates in ecosystems;
(h) The plausible types of improper management to which the waste could be subjected;
(i) The quantities of the waste generated at individual generation sites or on a statewide basis. Under this factor, the department will also consider whether or not the waste is listed under WAC 173-303-081 as a discarded chemical product and occurs in a relatively pure form. Any waste discarded chemical product which exceeds the quantity exclusion limit specified in WAC 173-303-081(2) for that waste will not be exempted;
(j) The nature and severity of the public health and environmental damage that has occurred as a result of the improper management of wastes containing the constituent(s);
(k) Actions taken by other governmental agencies or regulatory programs based on the health or environmental threat posed by the waste or waste constituent(s); and
(l) Such other factors as may be appropriate.
(5) Reserve.
(6) Bases for categorically excluding classes of wastes. This subsection does not apply to any waste class that includes hazardous waste regulated under 40 C.F.R. Part 261. To successfully petition the department to categorically exclude a class of wastes, petitioners must demonstrate to the satisfaction of the department that the petition or petitions for exclusion:
(a) Accurately describe the class of wastes for which categorical exclusion is sought and show that the class of wastes does not include any wastes which would be regulated as hazardous waste under 40 C.F.R. Part 261;
(b) Describe the variability or uniformity of the class of wastes over time and in relation to the individual wastes that comprise the class of waste;
(c) Discuss the generators and their individual wastes that belong to the class of wastes and, to the extent practical, any generators or individual wastes that, although belonging to the class of wastes, are not represented by the petition or petitions; and
(d) For each individual waste within the class of wastes, provide the demonstration described by subsection (3) of this section, except that where it is determined by consultation with the department to be impractical to provide the demonstration for each individual waste, the petitioner or petitioners will provide the demonstration for samples of the individual wastes determined by consultation with the department to be representative of the class of wastes.

Conditional exclusion of special wastes.

(1) Purpose and applicability. Special wastes pose a relatively low hazard to human health and the environment. The department believes that special wastes can be safely managed with a level of protection that is intermediate between dangerous and nondangerous solid wastes. This section establishes a conditional exclusion for the management of special wastes. The definition for special waste is found in WAC 173-303-040.
(2) Exclusion. Special wastes are excluded from the requirements of chapter 173-303 WAC, except for WAC 173-303-050; 173-303-060; 173-303-140 (4)(c); 173-303-145; 173-303-960; and 173-303-510 excluding subsections (4)(a), (4)(b)(iii), (5), (6)(c), and (6)(d). In addition, special waste must be treated as dangerous waste for purposes of pollution prevention planning as required in chapters 173-307 and 173-305 WAC. Special wastes will not be considered as dangerous waste, provided they are managed in accordance with the standards in this subsection and provided they are disposed, legitimately recycled, or treated on-site consistent with the requirements of WAC 173-303-170 (2)(b)(v).
(a) Generators may not accumulate special waste on-site for more than one hundred eighty days from the date the quantity of waste exceeds two thousand two hundred pounds. The generator must keep a written record showing the dates when accumulation of the wastes began;
(b) During accumulation, special waste must be stored in a manner to prevent releases to the environment. This includes, but is not limited to, storing wastes in compatible containers, on impermeable surfaces, or in secondary containment structures, etc.;
(c) Facilities that receive special waste for recycling must meet the requirements of (b) of this subsection and store special wastes for no more than one hundred eighty days.
(d) All workers handling special wastes must be informed of the waste's potential hazard, either through worker training, health and safety plans, or notification of workers on a case-by-case basis;
(e) Special wastes must be transported directly from their site of generation to any off-site recycling, treatment, or disposal destination. The wastes must not pass through any intermediate solid waste processing facility, such as a transfer station, unless:
(i) The transfer station operator has made specific provisions for managing special waste by physical segregation, packing, or other means to ensure that workers and the public are not exposed to the waste stream at the transfer station;

Certification of designation.

(1) Purpose and applicability.
(a) The purpose of WAC 173-303-075 is to establish procedures by which the generator of a solid waste may apply to the department for a review of his waste, and for a determination of the designation of his waste. When a final determination is made, the department will issue a certificate of designation which will describe the status of the generator's waste with respect to the designation requirements of this chapter 173-303 WAC.
(b) The provisions of this section are applicable to any person who produces a solid waste, who may be subject to the requirements of this chapter 173-303 WAC as the generator of a dangerous waste and who wishes to obtain a certificate designating the status of his waste.
(2) Certification. Any person who produces a solid waste which could be a dangerous waste may apply to the department, in accordance with the guidelines published pursuant to WAC 173-303-075(4), for a certificate of designation for his waste.
(a) The certificate of designation will describe the status of the designation for a waste or wastes as follows:
(i) Either, the certificate will state that the waste or wastes listed in the certificate are designated dangerous waste; or
(ii) The certificate will state that the waste or wastes listed in the certificate are not designated dangerous waste under the designation lists or characteristics of WAC 173-303-080 through 173-303-090; or
(iii) The certificate will state that the waste or wastes listed in the certificate are not designated dangerous waste under the dangerous waste lists, characteristics or criteria, WAC 173-303-080 through 173-303-100.
(b) The certificate of designation will, at a minimum, include the following information:
(i) The name, address, telephone number and, where applicable, the EPA/state identification number of the person to whom the certificate is issued;
(ii) A statement of the status of the designation of the waste or wastes listed in the certificate and, if designated, whether DW or EHW;
(iii) A listing of the waste or wastes for which the certificate has been issued;
(iv) The signature of the director or his designee;
(v) The date on which the certificate was issued; and
(vi) The period of time or conditions for which the certificate is valid.
(c) Once a certificate of designation has been issued to a person, that person is no longer subject to the designation procedures of WAC 173-303-080 through 173-303-100, unless the period of time for which the certificate is valid expires, the conditions under which the certificate is valid change, or the department withdraws its certification of designation in accordance with WAC 173-303-075(5). If the certificate states that the waste or wastes listed in it are designated, then the person to whom the certificate is issued must comply with all applicable requirements of this chapter 173-303 WAC. If the certificate states that the waste or wastes listed in it are not designated, then the person to whom the certificate is issued is not subject to the requirements of this chapter 173-303 WAC, unless the certificate becomes invalid or the department withdraws its certification.
(d) While an application for a certificate of designation is pending final action by the department, the person applying for certification must comply with all applicable requirements of this chapter 173-303 WAC.
(e) While a certificate of designation is being amended, in accordance with WAC 173-303-075(5), the certificate will remain in effect except for those parts of the certificate which the department specifically suspends.
(3) Designation. Determination of the status of designation for a waste or wastes for which a certificate of designation is being sought will follow the procedures set forth in this subsection.
(a) A waste will be certified as a dangerous waste if it is designated under any of the methods set forth in WAC 173-303-080 through 173-303-100.
(b) A waste will be certified as not a dangerous waste if:
(i) It has only been checked against WAC 173-303-080 through 173-303-090 (lists and characteristics) and it is not designated; or
(ii) It has been checked against the dangerous waste lists, characteristics and criteria, WAC 173-303-080 through 173-303-100, and it is not designated.
(4) Application. Any person who wishes to apply for a certificate of designation must do so according to the certification guidelines published by and available from the department. The department will follow the procedures specified in the certification guidelines when considering an application for a certificate.
(5) Review of certification. Review of and changes to or withdrawal of certificates of designation will be performed by the department according to the procedures specified in the certification guidelines, available from the department. At a minimum, the certification guidelines provide for the following procedures:
(a) The department will periodically review each certificate of designation to insure that it is current and accurately states the proper designation for the waste or wastes listed on the certificate.
(b) The department may amend, or any person with a certificate of designation may request the department to amend, any certificate in the event that changes to the certificate are necessary to keep it current or maintain its accuracy. The person will obtain concurrence of the department if he wishes to amend his certificate to reflect changes in the information on the certificate (e.g., new wastes, changes in waste properties, changes of address, etc.).
(c) The department reserves the authority to withdraw any certificate of designation if there is reason to believe that the certificate results in a threat to public health or the environment. If a certificate is withdrawn, then the waste or wastes listed on the certificate will be subject to all applicable requirements of this chapter 173-303 WAC.

PDF173-303-081

Discarded chemical products.

(1) A waste will be designated as a dangerous waste and assigned a "P" or "U" code if it is handled in any of the manners described in (e) of this subsection, and if it is a residue from the management of:
(a) A commercial chemical product or manufacturing chemical intermediate (see definition in WAC 173-303-040) which has the generic name listed in the discarded chemical products list, WAC 173-303-9903;
(b) An off-specification commercial chemical product or manufacturing chemical intermediate which if it had met specifications would have the generic name listed in the discarded chemical products list, WAC 173-303-9903;
(c) Any containers, inner liners, or residue remaining in a container or in an inner liner removed from a container that has held any commercial chemical product or manufacturing chemical intermediate that has, or any off-specification commercial chemical product or manufacturing chemical intermediate which if it had met specifications would have, the generic name listed on the "P" or "U" discarded chemical products list of WAC 173-303-9903, unless the containers or inner liners are empty as described in WAC 173-303-160(2) or 173-303-555(8);
(d) Any residue or contaminated soil, water, or other debris resulting from the cleanup of a spill of a commercial chemical product or manufacturing chemical intermediate which has, or of an off-specification commercial chemical product or manufacturing chemical intermediate which if it had met specifications would have, the generic name listed in the discarded chemical products list, WAC 173-303-9903;
(e) The materials or items described in (a), (b), (c), and (d) of this subsection are dangerous wastes when they are:
(i) Discarded or intended to be discarded as described in WAC 173-303-016 (3)(b)(i);
(ii) Burned for purposes of energy recovery in lieu of their original intended use;
(iii) Used to produce fuels in lieu of their original intended use;
(iv) Applied to the land in lieu of their original intended use; or
(v) Contained in products that are applied to the land in lieu of their original intended use.
(2) Quantity exclusion limits:
(a) A person with a waste or wastes (including residues from the management of wastes) identified in subsection (1) of this section, will be a dangerous waste generator (and may not be considered a small quantity generator as determined in WAC 173-303-169(3)) if the amount of their waste exceeds the following quantity exclusion limits:
(i) For chemicals designated on the "P" discarded chemical products list of WAC 173-303-9903 - 2.2 lbs. (1.0 kg) per month or per batch. Such wastes are designated DW and are identified as acute hazardous wastes;
(ii) For chemicals, and for residues from the cleanup of spills involving chemicals, designated on the "U" discarded chemical products list of WAC 173-303-9903 - 220 lbs. (100 kg) per month or per batch. Such wastes are designated DW;
(iii) For containers or inner liners which held any chemical designated on the "P" discarded chemical products list of WAC 173-303-9903 - 2.2 lbs. (1.0 kg) of residue remaining in the containers or inner liners per month or per batch unless the containers or inner liners meet the definition of empty and have been triple rinsed as described in WAC 173-303-160(2). Such wastes are designated DW and are identified as acute hazardous wastes;
(iv) For residues, contaminated soil, water, or other debris resulting from the cleanup of a spill, into or on any land or water, of any chemical designated on the "P" discarded chemical products list of WAC 173-303-9903 - 220 lbs. (100 kg) per month or per batch. Such wastes are designated DW and are identified as acute hazardous wastes.
(b) A person's total monthly waste quantity is the sum of all their wastes which share a common quantity exclusion limit (e.g., the total quantity of all discarded chemical products with a 2.2 pound QEL, the total quantity of all residues contaminated by discarded chemical products with a 2.2 pound QEL, etc.) which were generated during a month or a batch operation at each specific waste generation site.
(3) Dangerous waste numbers and mixtures. A waste that has been designated as a discarded chemical product dangerous waste must be assigned the dangerous waste number or numbers listed in WAC 173-303-9903 next to the generic chemical or chemicals that caused the waste to be designated. A mixture of a solid waste with a waste that would be designated as a discarded chemical product under this section must be designated. The mixture designation is the same as the designation for the discarded chemical product that was mixed with the solid waste unless it has been excluded under WAC 173-303-070 (2)(c). For example, a mixture containing 2.2 lbs. (1 kg) of Aldrin (dangerous waste number P004, DW designation, QEL of 2.2 lbs.) and 22 lbs. (10 kg) of a solid waste, would be designated DW, and identified as acute hazardous waste. The mixture would have the dangerous waste number P004.

Dangerous waste sources.

(1) The dangerous waste sources list appears in WAC 173-303-9904. Any waste that is listed or is a residue from the management of a waste listed on the dangerous waste sources list must be designated a dangerous waste, and identified as DW. Dangerous waste sources codes include WPCB or codes that begin with an "F" or "K."
(2) Quantity exclusion limit. A person whose waste is listed in WAC 173-303-9904 (including residues from the management of such wastes) is a dangerous waste generator (and may not be considered a small quantity generator as provided in WAC 173-303-170(2)) if the amount of their waste exceeds the following quantity exclusion limits:
(a) 2.2 lbs. (1 kg) per month or per batch for wastes listed with the dangerous waste numbers F020, F021, F022, F023, F026, or F027. These wastes are designated DW and identified as acute hazardous wastes;
(b) 220 lbs. (100 kg) per month or per batch of any residue or contaminated soil, water, or other debris resulting from the cleanup of a spill, into or on any land or water of a waste listed in (a) of this subsection, or of an acute hazardous waste listed in WAC 173-303-9904 under specific sources ("K" wastes). Note: Acute hazardous K listed wastes are followed by an "H." These wastes are designated DW and identified as acute hazardous wastes; or
(c) 220 lbs. (100 kg) per month or per batch for all other wastes.
(3) Care should be taken in the proper designation of these wastes and of mixtures of these wastes and solid wastes. A mixture of a solid waste with a waste that would be designated as a dangerous waste source under this section must be designated as a dangerous waste source unless it has been excluded under WAC 173-303-070 (2)(c). The mixture has the same designation (DW), and the same dangerous waste number as the dangerous waste source which was mixed with the solid waste.

(2) Representative samples. The department will consider a sample obtained using any of the applicable sampling methods described in WAC 173-303-110(2), sampling and testing methods, to be a representative sample.
(3) Equivalent test methods. The testing methods specified in this section are the only acceptable methods, unless the department approves an equivalent test method in accordance with WAC 173-303-910(2).
(4) Quantity exclusion limit. A solid waste is a dangerous waste if it exhibits one or more of the dangerous waste characteristics described in subsections (5), (6), (7), and (8) of this section. If a person's solid waste exhibits one or more of these characteristics, then he or she is a dangerous waste generator (and may not be considered a small quantity generator as provided in WAC 173-303-170(2)) if the quantity of their waste exceeds 220 lbs. (100 kg) per month or per batch.
(5) Characteristic of ignitability.
(a) A solid waste exhibits the characteristic of ignitability if a representative sample of the waste has any of the following properties:
(i) It is a liquid, other than an aqueous solution containing less than 24 percent alcohol by volume, and has a flash point less than 60 degrees C (140 degrees F), as determined by a Pensky-Martens Closed Cup Tester, using the test method specified in ASTM Standard D93-06, or a Setaflash Closed Cup Tester, using the test method specified in ASTM Standard D3278-96 (2004)e1 as incorporated by reference at WAC 173-303-110 (3)(h)(v) and (vi);
(ii) It is not a liquid and is capable, under standard temperature and pressure, of causing fire through friction, absorption of moisture or spontaneous chemical changes and, when ignited, burns so vigorously and persistently that it creates a hazard;
(iii) It is an ignitable compressed gas.
(A) The term "compressed gas" applies to any material or mixture having in the container an absolute pressure exceeding 40 p.s.i. at 70 degrees F or, regardless of the pressure at 70 degrees F, having an absolute pressure exceeding 104 p.s.i. at 130 degrees F; or any liquid flammable material having a vapor pressure exceeding 40 p.s.i. absolute at 100 degrees F as determined by ASTM Test D-323.
(B) A compressed gas must be characterized as ignitable if any one of the following occurs:
(I) Either a mixture of 13 percent or less (by volume) with air forms a flammable mixture or the flammable range with air is wider than 12 percent regardless of the lower limit. These limits must be determined at atmospheric temperature and pressure. The method of sampling and test procedure must be acceptable to the Bureau of Explosives and approved by the director, Pipeline and Hazardous Materials Technology, U.S. Department of Transportation (see Note 2).
(II) Using the Bureau of Explosives' Flame Projection Apparatus (see Note 1), the flame projects more than 18 inches beyond the ignition source with valve opened fully, or the flame flashes back and burns at the valve with any degree of valve opening.
(III) Using the Bureau of Explosives' Open Drum Apparatus (see Note 1), there is any significant propagation of flame away from the ignition source.
(IV) Using the Bureau of Explosives' Closed Drum Apparatus (see Note 1), there is any explosion of the vapor-air mixture in the drum; or,
(iv) It is an oxidizer. An oxidizer for the purpose of this subsection is a substance such as a chlorate, permanganate, inorganic peroxide, or a nitrate, that yields oxygen readily to stimulate the combustion of organic matter (see Note 4).
An organic compound containing the bivalent -O-O-structure and which may be considered a derivative of hydrogen peroxide where one or more of the hydrogen atoms have been replaced by organic radicals must be classed as an organic peroxide unless:
(A) It is a forbidden explosive as defined in 49 C.F.R. 173.54, or a Class 1 explosive, Division 1.1, Division 1.2, Division 1.3, and Division 1.5, as defined in 49 C.F.R. 173.50, in which case it must be classed as an explosive;
(B) The material is forbidden to be offered for transportation according to 49 C.F.R. 172.101 and 49 C.F.R. 173.21;
(C) It is determined that the predominant hazard of the material containing an organic peroxide is other than that of an organic peroxide; or
(D) According to data on file with the Pipeline and Hazardous Materials Safety Administration in the U.S. Department of Transportation (see Note 3), it has been determined that the material does not present a hazard in transportation.
Note 1:
A description of the Bureau of Explosives' Flame Projection Apparatus, Open Drum Apparatus, Closed Drum Apparatus, and method of tests may be procured from the Bureau of Explosives.
Note 2:
As part of a U.S. Department of Transportation (DOT) reorganization, the Office of Hazardous Materials Technology (OHMT), which was the office listed in the 1980 publication of 49 C.F.R. 173.300 for the purposes of approving sampling and test procedures for a flammable gas, ceased operations on February 20, 2005. OHMT programs have moved to the Pipeline and Hazardous Materials Safety Administration (PHMSA) in the DOT.
Note 3:
As part of a U.S. Department of Transportation (DOT) reorganization, the Research and Special Programs Administration (RSPA), which was the office listed in the 1980 publication of 49 C.F.R. 173.151a for the purposes of determining that a material does not present a hazard in transport, ceased operations on February 20, 2005. RSPA programs have moved to the Pipeline and Hazardous Materials Safety Administration (PHMSA) in the DOT.
Note 4:
The DOT regulatory definition of an oxidizer was contained in Sec. 173.151 of 49 C.F.R., and the definition of an organic peroxide was contained in paragraph 173.151a. An organic peroxide is a type of oxidizer.
(b) A solid waste that exhibits the characteristic of ignitability must be designated DW, and assigned the dangerous waste number of D001.
(6) Characteristic of corrosivity.
(a) A solid waste exhibits the characteristic of corrosivity if a representative sample of the waste has any one or more of the following properties:
(i) It is aqueous and has a pH less than or equal to 2, or greater than or equal to 12.5, as determined by a pH meter using Method 9040C in "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods," EPA Publication SW-846, as incorporated by reference in WAC 173-303-110 (3)(a);
(ii) It is liquid and corrodes steel (SAE 1020) at a rate greater than 0.250 inch (6.35 mm) per year at a test temperature of 55 degrees C (130 degrees F) as determined by the test method specified in NACE (National Association of Corrosion Engineers) Standard TM0169-2000 as standardized in "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods," (Method 1110A) EPA Publication SW-846, as incorporated by reference in WAC 173-303-110 (3)(a); or
(iii) It is solid or semisolid which, upon testing using Method 9045D in "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods" (SW 846), results in a pH less than or equal to 2, or greater than or equal to 12.5.
(b) A solid waste that exhibits the characteristic of corrosivity because:
(i) It has either of the properties described in (a)(i) or (ii) of this subsection will be designated DW, and assigned the dangerous waste number of D002;
(ii) It only has the property described in (a)(iii) of this subsection will be designated DW, and assigned the dangerous waste number of WSC2.
(7) Characteristic of reactivity.
(a) A solid waste exhibits the characteristic of reactivity if a representative sample of the waste has any of the following properties:
(i) It is normally unstable and readily undergoes violent change without detonating;
(ii) It reacts violently with water;
(iii) It forms potentially explosive mixtures with water;
(iv) When mixed with water, it generates toxic gases, vapors or fumes in a quantity sufficient to present a danger to human health or the environment;
(v) It is a cyanide or sulfide bearing waste which, when exposed to pH conditions between 2 and 12.5 can generate toxic gases, vapors or fumes in a quantity sufficient to present a danger to human health or the environment;
(vi) It is capable of detonation or explosive reaction if it is subjected to a strong initiating source or if heated under confinement;
(vii) It is readily capable of detonation or explosive decomposition or reaction at standard temperature and pressure; or
(viii) It is a forbidden explosive as defined in 49 C.F.R. 173.54, or a Class 1 explosive, Division 1.1, Division 1.2, Division 1.3, and Division 1.5, as defined in 49 C.F.R. 173.50 and 173.53.
(b) A solid waste that exhibits the characteristic of reactivity must be designated DW, and assigned the dangerous waste number of D003.
(8) Toxicity characteristic.
(a) A solid waste exhibits the characteristic of toxicity if, using the Toxicity Characteristic Leaching Procedure (TCLP), test Method 1311 in "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods," EPA Publication SW-846, as incorporated by reference in WAC 173-303-110 (3)(a), the extract from a representative sample of the waste contains any of the contaminants listed in the toxicity characteristic list in (c) of this subsection, at concentrations equal to or greater than the respective value given in the list. When the waste contains less than 0.5 percent filterable solids, the waste itself, after filtering using the methodology outlined in Method 1311, is considered to be the extract for the purpose of this subsection.
(b) A solid waste that exhibits the toxicity characteristic has the dangerous waste number specified in the list which corresponds to the toxic contaminant causing it to be dangerous.
(c) Toxicity characteristic list. Any waste that contains contaminants which occur at concentrations at or above the DW threshold must be designated DW.

Dangerous waste criteria.

(1) Purpose. The purpose of this section is to describe methods for determining if a solid waste is a dangerous waste by the criteria set forth in this section. The dangerous waste criteria consist of:
(a) Toxic dangerous wastes; and
(b) Persistent dangerous wastes.
(2) References. The following toxicity data sources are adopted by reference:
(a) The National Institute for Occupational Safety and Health's (NIOSH) Registry of Toxic Effects of Chemical Substances (RTECS), Superintendent of Documents, U.S. Government Printing Office, Washington, DC 20402.
(b) The United States Environmental Protection Agency, Ecotoxicology Database (ECOTOX), Mid-Continent Ecology Division, 6201 Congdon Boulevard, Duluth, MN 55804.
(c) The United States National Library of Medicine Toxicology Data Network, Hazardous Substance Database (HSDB), 8600 Rockville Pike, Bethesda, MD 20894.
(3) A person must use data that are available to him or her, and, when such data are inadequate for the purposes of this section, must refer to the references identified in WAC 173-303-100(2) to determine:
(a) Toxicity data or toxic category for each known constituent in the waste;
(b) Whether or not each known constituent of the waste is a halogenated organic compound or a polycyclic aromatic hydrocarbon as defined in WAC 173-303-040.
(4) Quantity exclusion limit. A solid waste is a dangerous waste if it meets one or more of the dangerous waste criteria described in subsections (5) and (6) of this section. If a person's solid waste meets one or more of these criteria then he or she is a dangerous waste generator (and may not be considered a small quantity generator as provided in WAC 173-303-170(2)) if the quantity of the waste exceeds the following quantity exclusion limits:
(a) For toxic dangerous wastes designated as EHW (WT01), the quantity exclusion limit is 2.2 lbs. per month.
(b) For any WT01 residue or contaminated soil, water, or other debris resulting from the clean up of a spill, into or on any land or water, the quantity exclusion limit is 220 lbs. per month.
(c) For all other wastes designating under this section the quantity exclusion limit is 220 lbs. (100 kg) per month or per batch.
(5) Toxicity criteria. Except as provided in WAC 173-303-070 (4) or (5), a person must determine if a solid waste meets the toxicity criteria under this section by following either the instructions for book designation, when his knowledge of the waste is sufficient, or by testing the waste using the biological testing methods adopted under WAC 173-303-110(3).
(a) Except as provided in WAC 173-303-070(4), if a person knows only some of the toxic constituents in the waste or only some of the constituent concentrations, and if the waste is undesignated for those known constituents or concentrations, then the waste is not designated for toxicity under this subsection.
(b) Book designation procedure. A person may determine if a waste meets the toxicity criteria by following the book designation instructions as follows:
(i) A person must determine the toxic category for each known constituent. The toxic category for each constituent may be determined from available data, for example, Registry for Toxic Effects of Chemical Substances (RTECS), Hazardous Substances Data Bank (HSDB), and Ecotoxicology database (ECOTOX). The toxic category should then be identified, using the table below. If data are available for more than one test endpoint (that is, fish, oral rat, inhalation rat, or dermal rabbit), the value with the highest toxicity must be used. Similarly, if toxicity data do not agree on the same toxic category within the same test endpoint, the value with the highest toxicity must be used.a Finally, if toxicity data for a constituent cannot be found in reasonably available sources (for example, RTECS, HSDB or ECOTOX), the toxic category for that constituent need not be determined.

These four test endpoints are defined in WAC 173-303-040.
 
b
Fish LC50 data must be derived from an exposure period greater than or equal to twenty-four hours. A hierarchy of species LC50 data should be used that includes (in decreasing order of preference) salmonids, fathead minnows, and other fish species.
 
c
Inhalation Rat LC50 data must be derived from an exposure period greater than or equal to one hour.
(ii) A person whose waste contains one or more toxic constituents must determine the equivalent concentration for the waste from the following formula:

where ∑(X,A,B,C, or D)% is the sum of all the concentration percentages for a particular toxic category.
Example 1. A person's waste contains: Aldrin (A Category) - .01%; Endrin (A Category) - 1%; Benzene (D Category) - 4%; Phenol (C Category) - 2%; Dinoseb (B Category) - 5%; Water (nontoxic) - 87%. The equivalent concentration (E.C.) would be:
E.C. (%)

=
0% + 0.101% + 0.05% + 0.002% + 0.0004% = 0.1534%
So the equivalent concentration equals 0.1534%.
(iii) A person whose waste contains toxic constituents must determine its designation according to the value of the equivalent concentration:
(A) If the equivalent concentration is less than 0.001%, the waste is not a toxic dangerous waste; or
(B) If the equivalent concentration is equal to or greater than 0.001% and less than 1.0%, the person will designate the waste as DW and assign the dangerous waste number WT02; and
(C) If the equivalent concentration is equal to or less than 0.01%, the DW may also be a special waste; or
(D) If the equivalent concentration is equal to or greater than 1.0%, the person will designate the waste as EHW and assign the dangerous waste number WT01.
Example 1. Continued. The equivalent concentration of 0.1534% (from Example 1. above) is greater than 0.001% and less than 1.0%. The waste is DW and the dangerous waste number WT02 must be assigned.
(iv) Reserve.
(c) Designation from bioassay data. A person may determine if a waste meets the toxicity criteria by following the bioassay designation instructions of either:
(i) The DW bioassay. To determine if a waste is DW, a person must establish the toxicity category range of a waste by means of the 100 mg/L acute static fish test, as described in the biological testing methods (bioassay) adopted in WAC 173-303-110(3). If data from the test indicates that the waste is DW, then the person will assign the dangerous waste number WT02. Otherwise, the waste is not regulated as toxic dangerous waste. No further testing must be done except as provided in WAC 173-303-070 (4) and (5), or if the person chooses to determine whether the waste is EHW, or in the case of state-only solid dangerous waste, if the person chooses to determine whether the waste is special waste; or
(ii) The EHW and special waste bioassay. To determine if a waste is EHW, a person must establish the toxicity of a waste by means of the fish bioassay at 10 mg/L, as described in the biological testing methods (bioassay) adopted in WAC 173-303-110(3). (NOTE: A fish bioassay at 1 mg/L corresponds with the definition of EHW, which includes toxic categories X-B. However, the fish bioassay is not reproducible at these low levels.) If data from the test indicates that the waste is EHW, then the person will assign the dangerous waste number WT01. Otherwise, the waste will be designated DW, and the person will assign the dangerous waste number WT02. A person with state-only solid waste may choose to test a waste to determine if it is special waste. Testing levels for special waste must be at 10 mg/L for the fish bioassay. No further testing must be done except as provided in WAC 173-303-070 (4) and (5), or if the person chooses to test the waste in accordance with WAC 173-303-100 (5)(c)(i) to determine if the waste is not regulated as toxic dangerous waste.
(d) If the designation acquired from book designation and bioassay data do not agree, then bioassay data will be used to designate a waste. If a waste is designated as DW or EHW following the book designation procedure, a person may test the waste by means of the biological testing methods (bioassay) adopted under WAC 173-303-110(3) to demonstrate that the waste is not a dangerous waste or should be designated as DW and not EHW.
(e) A waste designated as DW by toxicity criteria must be assigned the dangerous waste number of WT02. A waste designated as EHW by toxicity criteria must be assigned the dangerous waste number of WT01.
(6) Persistence criteria. For the purposes of this section, persistent constituents are chemical compounds which are either halogenated organic compounds (HOC), or polycyclic aromatic hydrocarbons (PAH), as defined under WAC 173-303-040. Except as provided in WAC 173-303-070 (4) or (5), a person may determine the identity and concentration of persistent constituents by either applying knowledge of the waste or by testing the waste according to WAC 173-303-110 (3)(c) Chemical Testing Methods for Designating Dangerous Waste Publication #97-407.
(a) Except as provided in WAC 173-303-070(4), if a person knows only some of the persistent constituents in the waste, or only some of the constituent concentrations, and if the waste is undesignated for those known constituents or concentrations, then the waste is not designated for persistence under this subsection.
(b) When a waste contains one or more halogenated organic compounds (HOC) for which the concentrations are known, the total halogenated organic compound concentration must be determined by summing the concentration percentages for all of the halogenated organic compounds for which the concentration is known.
Example 2. A waste contains: Carbon tetrachloride - .009%; DDT - .012%; 1,1,1 - trichloroethylene - .020%. The total halogenated organic compound concentration would be:
Total HOC Concentration (%) = .009% + .012% +.020% =.041%
(c) A person whose waste contains polycyclic aromatic hydrocarbons (PAH) as defined in WAC 173-303-040, must determine the total PAH concentration by summing the concentration percentages of each of the polycyclic aromatic hydrocarbons for which they know the concentration.
Example 3. A person's waste contains: Chrysene - .08%; 3,4 - benzo(a)pyrene - 1.22%. The total polycyclic aromatic hydrocarbon concentration would be:
Total PAH Concentration (%) = .08% + 1.22% = 1.30%
(d) A person whose waste contains halogenated organic compounds and/or polycyclic aromatic hydrocarbons must determine its designation from the persistent dangerous waste table.

Recycled, reclaimed, and recovered wastes.

(1) This section describes the requirements for persons who recycle materials that are solid wastes and dangerous. Except as provided in subsections (2) and (3) of this section, dangerous wastes that are recycled are subject to the requirements for generators, transporters, and storage facilities of subsection (4) of this section. Dangerous wastes that are recycled will be known as "recyclable materials."
(2)(a) The following recyclable materials are solid wastes and sometimes are dangerous wastes. However, they are subject only to the requirements of (b) of this subsection, WAC 173-303-050, 173-303-145 and 173-303-960:
(i) Industrial ethyl alcohol that is reclaimed except that exports and imports of such recyclable materials must comply with the requirements of 40 C.F.R. Part 262, Subpart H. See export requirements at 40 C.F.R. 261.6 (a)(3)(i)(A) and (B) that are incorporated by reference at WAC 173-303-230(1);
(ii) (Reserved);
(iii) (Reserved);
(iv) Scrap metal that is not excluded under WAC 173-303-071 (3)(ff);
(v) Fuels produced from the refining of oil-bearing dangerous wastes along with normal process streams at a petroleum refining facility if such wastes result from normal petroleum refining, production, and transportation practices (this exemption does not apply to fuels produced from oil recovered from oil-bearing dangerous wastes where such recovered oil is already excluded under WAC 173-303-071 (3)(cc));
(vi) (Reserved);
(vii) Coke and coal tar from the iron and steel industry that contains dangerous waste from the iron and steel production process;
(viii)(A) Dangerous waste fuel produced from oil-bearing dangerous wastes from petroleum refining, production, or transportation practices, or produced from oil reclaimed from such dangerous wastes, where such dangerous wastes are reintroduced into a process that does not use distillation or does not produce products from crude oil so long as the resulting fuel meets the used oil specification under 40 C.F.R. 279.11 (which is incorporated by reference at WAC 173-303-515(4)) and so long as no other dangerous wastes are used to produce the dangerous waste fuel;
(B) Dangerous waste fuel produced from oil-bearing dangerous waste from petroleum refining production, and transportation practices, where such dangerous wastes are reintroduced into a refining process after a point at which contaminants are removed, so long as the fuel meets the used oil fuel specification under 40 C.F.R. 279.11 (which is incorporated by reference at WAC 173-303-515(4)); and
(C) Oil reclaimed from oil-bearing dangerous wastes from petroleum refining, production, and transportation practices, which reclaimed oil is burned as a fuel without reintroduction to a refining process, so long as the reclaimed oil meets the used oil fuel specification under 40 C.F.R. 279.11 (which is incorporated by reference at WAC 173-303-515(4)).
(b) Any recyclable material listed in (a) of this subsection will be subject to the applicable requirements listed in subsection (4) of this section if the department determines, on a case-by-case basis, that:
(i) It is being accumulated, used, reused, or handled in a manner that poses a threat to public health or the environment; or
(ii) Due to the dangerous constituent(s) in it, any use or reuse would pose a threat to public health or the environment. Such recyclable material will be listed in WAC 173-303-016(6).
(3) The recyclable materials listed in (a) through (h) of this subsection are not subject to the requirements of this section but are subject to the requirements of WAC 173-303-070 through 173-303-110, 173-303-160, 173-303-500 through 173-303-525, and all applicable provisions of WAC 173-303-800 through 173-303-840. The recyclable materials listed in (b), (d), (f) and (g) of this subsection are also subject to WAC 173-303-140.
In addition to these requirements, owners and operators of facilities that receive recyclable materials from off-site are subject to WAC 173-303-610 (2) and (12) and to WAC 173-303-620 (1)(e).
(a) Recycling requirements for state-only dangerous wastes (see WAC 173-303-500);
(b) Recyclable materials used in a manner constituting disposal (see WAC 173-303-505);
(c) Spent CFC or HCFC refrigerants that are recycled on-site or sent to be reclaimed off-site (see WAC 173-303-506);
(d) Dangerous wastes burned (as defined in WAC 173-303-510 (1)(a)) in boilers and industrial furnaces that are not regulated under Subpart O of 40 C.F.R. Part 265 or WAC 173-303-670 (see WAC 173-303-510);
(e) (Reserved);
(f) Spent lead-acid batteries that are being reclaimed (see WAC 173-303-520);
(g) Recyclable materials from which precious metals are reclaimed (see WAC 173-303-525); and
(h) Spent antifreeze that is recycled on-site or sent to be recycled off-site (see WAC 173-303-522).
(4) Those recycling processes not specifically discussed in subsections (2) and (3) of this section are generally subject to regulation only up to and including storage prior to recycling. For the purpose of this section, the department may determine on a case-by-case basis that recyclable materials received from off-site are not stored if they are moved into an active recycling process within a period of time not to exceed seventy-two hours after being received. In making such a determination, the department will consider factors including, but not limited to, the types and volumes of wastes being recycled, operational factors of the recycling process, and the compliance history of the owner or operator. An active recycling process refers to a dynamic recycling operation that occurs within a recycling unit such as a distillation or centrifuge unit. The phrase does not refer to passive storage-like activities that occur, for example, when tanks or containers are used for phase separation or for settling impurities. Passive storage-like activities are not eligible for the recycling exemption under this subsection.
The recycling process itself is generally exempt from permitting unless the department determines, on a case-by-case basis, that the recycling process poses a threat to public health or the environment.
Unless specified otherwise in subsections (2) and (3) of this section:
(a) Generators of recyclable materials are subject to all applicable requirements of this chapter including, but not limited to, WAC 173-303-170 through 173-303-230;
(b) Transporters of recyclable materials are subject to all applicable requirements of this chapter including, but not limited to, WAC 173-303-240 through 173-303-270;
(c) Owners or operators of facilities that receive recyclable materials from off-site and recycle these recyclable materials without storing them before they are recycled are subject to the following requirements:
(i) WAC 173-303-060,
(ii) WAC 173-303-120 (4)(e),
(iii) WAC 173-303-283 through 173-303-290,
(iv) WAC 173-303-310 through 173-303-395,
(v) WAC 173-303-610 (2) and (12),
(vi) WAC 173-303-620 (1)(e),
(vii) WAC 173-303-630 (2) through (10), and
(viii) WAC 173-303-640 (2) through (10) except that requirements to post-closure planning or care in WAC 173-303-640(8) will not apply to closure of recycling units. In lieu of the dates in WAC 173-303-640 (2) and (4), for existing tank systems regulated under this subsection, owners and operators must complete the assessment of the tank system's integrity by June 1, 1992, and must meet the secondary containment requirements of WAC 173-303-640(4) by January 12, 1993;
(ix) The owner or operator must obtain data, by screening-type analysis if necessary, confirming the designation of each waste stream, such that each dangerous waste received can be effectively recycled without jeopardizing human health or the environment. The owner or operator must verify the waste designation periodically, so that it is accurate and current, but at least once every six months or on a batch basis if shipments of a specific waste stream are less frequent. Copies of all analyses and data must be retained for at least five years and made available to the department upon request.
(d) Owners and operators of facilities that store recyclable materials before they are recycled are subject to the following requirements including, but not limited to:
(i) For all recyclers, the applicable provisions of:
(A) WAC 173-303-280 through 173-303-395,
(B) WAC 173-303-800 through 173-303-840,

Land disposal restrictions.

(1) Purpose.
(a) The purpose of this section is to encourage the best management practices for dangerous wastes according to the priorities of RCW 70.105.150 which are, in order of priority:
(i) Reduction;
(ii) Recycling;
(iii) Physical, chemical, and biological treatment;
(iv) Incineration;
(v) Stabilization and solidification; and
(vi) Landfill.
(b) This section identifies dangerous wastes that are restricted from land disposal, describes requirements for restricted wastes, and defines the circumstances under which a prohibited waste may continue to be land disposed.
(c) For the purposes of this section, the term "landfill," as stated in the priorities of RCW 70.105.150, will be the same as the term "land disposal." Land disposal will be used in this section to identify the lowest waste management priority.
(2) Applicability.
The land disposal restrictions of this section apply to any person who owns or operates a dangerous waste treatment, storage, or disposal facility in Washington state and to any person who generates or transports dangerous waste.
(a) Land disposal restrictions for wastes designated in accordance with WAC 173-303-070 (3)(d)(i) through (iii) are the restrictions set forth by the Environmental Protection Agency in 40 C.F.R. Part 268 which are incorporated by reference into this regulation, as modified in (c) through (f) of this subsection, and the restrictions set forth in subsections (3) through (7) of this section. The words "regional administrator" (in 40 C.F.R.) will mean the "department," except for 40 C.F.R. Parts 268.5 and 268.6; 268 Subpart B; 268.42(b) and 268.44 (a) through (g). The authority for implementing these excluded C.F.R. sections remains with the U.S. Environmental Protection Agency. The word "EPA" (in 40 C.F.R.) means "Ecology" at 40 C.F.R. 268.44(m) and 268.45(a). The exemption and exception provisions of subsections (3) through (7) of this section are not applicable to the federal land disposal restrictions.
Where the federal regulations that have been incorporated by reference refer to 40 C.F.R. 260.11, data provided under this section must instead meet the requirements of WAC 173-303-110.
(b) Land disposal restrictions for state-only dangerous waste are the restrictions set forth in subsections (3) through (7) of this section.
(c) Where 40 C.F.R. 268.7 (a)(1) is incorporated by reference, delete the sentence "Alternatively, the generator must send the waste to a RCRA-permitted hazardous waste treatment facility, where the waste treatment facility must comply with the requirements of 264.13 of this chapter and paragraph (b) of this section."
(d) Where 40 C.F.R. 268.7 (a)(2) is incorporated by reference:
(i) Delete the words "or if the generator chooses not to make the determination of whether their waste must be treated" from the first sentence; and
(ii) Delete the sentence "(Alternatively, if the generator chooses not to make the determination of whether the waste must be treated, the notification must include the EPA Hazardous Waste Numbers and Manifest Number of the first shipment and must state 'This hazardous waste may or may not be subject to the LDR treatment standards. The treatment facility must make the determination'.)"
(e) Where 40 C.F.R. 268.7 (b)(6) is incorporated by reference, replace the words "for the initial shipment of waste, prepare a one-time certification described in paragraph (b)(4) of this section, and a one-time notice which includes the information in paragraph (b)(3) of this section (except the manifest number)" with the words "submit a certification described in paragraph (b)(4) of this section, and a notice which includes the information listed in paragraph (b)(3) of this section (except for the manifest number) to the department for each shipment".
(f) Where 40 C.F.R. 268.9(d) is incorporated by reference, replace paragraph (d) with the following: Wastes that exhibit a characteristic are also subject to Section 268.7 requirements, except that once the waste is no longer dangerous, a one-time notification and certification must be placed in the generators or treaters files and sent to the department. The notification and certification that is placed in the generators or treaters files must be updated if the process or operation generating the waste changes and/or if the subtitle D facility receiving the waste changes. However, the generator or treater need only notify the department on an annual basis if such changes occur. Such notification and certification should be sent to the department by the end of the calendar year, but no later than December 31.
(i) The notification must include the following information:
(A) Name and address of the RCRA Subtitle D facility receiving the waste shipment; and
(B) A description of the waste as initially generated, including the applicable dangerous waste code(s), treatability group(s), and underlying hazardous constituents (as defined in Sec. 268.2(i)), unless the waste will be treated and monitored for all underlying hazardous constituents. If all underlying hazardous constituents will be treated and monitored, there is no requirement to list any of the underlying hazardous constituents on the notice.
(ii) The certification must be signed by an authorized representative and must state the language found in Section 268.7 (b)(4).
If treatment removes the characteristic but does not meet standards applicable to underlying hazardous constituents, then the certification found in Sec. 268.7 (b)(4)(iv) applies.
(3) Definitions.
When used in this section the following terms have the meaning provided in this subsection. All other terms have the meanings given under WAC 173-303-040.
(a) "Dangerous waste constituents" means those constituents listed in WAC 173-303-9905 and any other constituents which have caused a waste to be a dangerous waste under this chapter.
(b) "Land disposal" means placement in a facility or on the land with the intent of leaving the dangerous waste at closure, and includes, but is not limited to, placement for disposal purposes in a: Landfill; surface impoundment; waste pile; injection well; land treatment facility; salt dome or salt bed formation; underground cave or mine; concrete vault or bunker.
(c) "Organic/carbonaceous waste" means a dangerous waste that contains combined concentrations of greater than ten percent organic/carbonaceous constituents in the waste; organic/carbonaceous constituents are those substances that contain carbon-hydrogen, carbon-halogen, or carbon-carbon chemical bonding.
(d) "Solid acid waste" means a dangerous waste that exhibits the characteristic of low pH under the corrosivity test of WAC 173-303-090 (6)(a)(iii).
(e) "Stabilization" and "solidification" mean a technique that limits the solubility and mobility of dangerous waste constituents. Solidification immobilizes a waste through physical means and stabilization immobilizes the waste by bonding or chemically reacting with the stabilizing material.
(4) Land disposal restrictions and prohibitions. The land disposal requirements of this subsection apply to land disposal in Washington state.
(a) Disposal of extremely hazardous waste (EHW). No person may land dispose of EHW, except as provided in subsection (5) of this section, at any land disposal facility in the state. No person may land dispose of EHW at the facility established under RCW 70.105.050, except as provided by subsections (5), (6), and (7) of this section. A person is encouraged to reclaim, recycle, recover, treat, detoxify, neutralize, or otherwise process EHW to remove or reduce its harmful properties or characteristics, provided that such processing is performed in accordance with the requirements of this chapter.
(b) Disposal of liquid waste. Special requirements for bulk and containerized liquids.
(i) The placement of bulk or noncontainerized liquid dangerous waste or dangerous waste containing free liquids (whether or not sorbents have been added) in any landfill is prohibited.
(ii) Containers holding free liquids must not be placed in a landfill unless:
(A) All free-standing liquid:
(I) Has been removed by decanting, or other methods; or
(II) Has been mixed with sorbent or stabilized (solidified) so that free-standing liquid is no longer observed; or
(III) Has been otherwise eliminated; or
(B) The container is very small, such as an ampule; or
(C) The container is designed to hold free liquids for use other than storage, such as a battery or capacitor; or
(D) The container is a labpack and is disposed of in accordance with WAC 173-303-161 and this chapter.
(iii) To demonstrate the absence or presence of free liquids in either a containerized or a bulk waste, the following tests must be used: Method 9095 (Paint Filter Liquids Test) as described in "Test Methods for Evaluating Solid Wastes, Physical/Chemical Methods" EPA Publication SW-846 as incorporated by reference in WAC 173-303-110 (3)(a).
(iv) Sorbents used to treat free liquids to be disposed of in landfills must be nonbiodegradable. Nonbiodegradable sorbents are: Materials listed or described in (b)(iv)(A) of this subsection; materials that pass one of the tests in (b)(iv)(B) of this subsection; or materials that are determined by the department to be nonbiodegradable through WAC 173-303-910.
(A) Nonbiodegradable sorbents.
(I) Inorganic minerals, other inorganic materials, and elemental carbon (e.g., aluminosilicates, clays, smectites, Fuller's earth, bentonite, calcium bentonite, montmorillonite, calcined montmorillonite, kaolinite, micas (illite), vermiculites, zeolites; calcium carbonate (organic free limestone); oxides/hydroxides, alumina, lime, silica (sand), diatomaceous earth; perlite (volcanic glass); expanded volcanic rock; volcanic ash; cement kiln dust; fly ash; rice hull ash; activated charcoal/activated carbon); or
(II) High molecular weight synthetic polymers (e.g., polyethylene, high density polyethylene (HDPE), polypropylene, polystyrene, polyurethane, polyacrylate, polynorborene, polyisobutylene, ground synthetic rubber, cross-linked allylstyrene and tertiary butyl copolymers). This does not include polymers derived from biological material or polymers specifically designed to be degradable; or
(III) Mixtures of these nonbiodegradable materials.
(B) Tests for nonbiodegradable sorbents.
(I) The sorbent material is determined to be nonbiodegradable under ASTM Method G21-96 (2002) - Standard Practice for Determining Resistance of Synthetic Polymer Materials to Fungi; or
(II) The sorbent material is determined to be nonbiodegradable under OECD (Organization for Economic Cooperation and Development) test 301B: [CO2 Evolution (Modified Sturm Test)].
(v) The placement of any liquid which is not a dangerous waste in a landfill is prohibited unless the owner or operator of such landfill demonstrates to the department, or the department determines, that:
(A) The only reasonably available alternative to the placement in such landfill is placement in a landfill or unlined surface impoundment, whether or not permitted or operating under interim status, which contains, or may reasonably be anticipated to contain, hazardous waste; and
(B) Placement in such owner or operator's landfill will not present a risk of contamination of any underground source of drinking water (as that term is defined in WAC 173-303-040).
(c) Disposal of solid acid waste. No person may land dispose solid acid waste, except as provided in subsection (5), (6), or (7) of this section. A person is encouraged to reclaim, recycle, recover, treat, detoxify, neutralize, or otherwise process these wastes to remove or reduce their harmful properties or characteristics, provided that such processing is performed in accordance with the requirements of this chapter.
(d) Disposal of organic/carbonaceous waste.
(i) No person may land dispose organic/carbonaceous waste, except as provided in subsection (5), (6), or (7) of this section. A person is encouraged to reclaim, recycle, recover, treat, detoxify, or otherwise process these wastes to remove or reduce their harmful properties or characteristics, provided that such processing is performed in accordance with the requirements of this chapter. Organic/carbonaceous wastes must be incinerated as a minimum management method according to the dangerous waste management priorities as defined in subsection (1)(a) of this section.
(ii) This prohibition against the land disposal of organic/carbonaceous waste does not apply to black mud generated from the caustic leach recovery of cryolite at primary aluminum smelting plants.
(iii) This prohibition against the land disposal of organic/carbonaceous waste does not apply to any person who certifies to the department that recycling, treatment and incineration facilities are not available within a radius of one thousand miles from Washington state's borders. Such certification must be sent to the department by certified mail or other means that establish proof of receipt (including applicable electronic means) and must include: The name, address and telephone number of the person certifying; a brief description of the organic/carbonaceous waste covered by the certification; a discussion of the efforts undertaken to identify available recycling, treatment and incineration facilities; and the signature of the person responsible for the certification and development of information used to support the certification. Records and information supporting the certification must be retained by the certifying person and must be made available to the department upon request.
A certification that has been properly submitted to the department will remain valid until the department determines that a recycling, treatment or incineration facility is available within a radius of one thousand miles from Washington state's borders and the person who submitted the certification is unable to demonstrate otherwise. A recycling, treatment or incineration facility will be considered by the department to be available if such facility: Is operating, and; can safely and legally recycle, treat or incinerate the organic/carbonaceous waste, and; has sufficient capacity to receive and handle significant amounts of the waste, and; agrees to accept the waste.
(5) Treatment in land disposal facilities. The land disposal restrictions in subsection (4) of this section do not apply to persons treating dangerous wastes in surface impoundments, waste piles, or land treatment facilities provided that such treatment is performed in accordance with the requirements of this subsection and this chapter.
(a) Surface impoundment treatment.
Liquid waste, extremely hazardous waste (EHW), solid acid waste, and organic/carbonaceous waste may be placed in surface impoundments for purposes of treatment provided the owner/operator can demonstrate that effective treatment of the dangerous waste constituents will occur and at closure the owner/operator complies with the prohibitions and restrictions of subsection (4) of this section.
(b) Waste pile treatment.
Liquid waste, extremely hazardous waste (EHW), solid acid waste, and organic/carbonaceous waste may be placed in waste piles for purposes of treatment provided the owner/operator can demonstrate that effective treatment of dangerous waste constituents will occur and that at closure the owner/operator will be in compliance with the prohibitions and restrictions of subsection (4) of this section.
(c) Land treatment.
Liquid waste, extremely hazardous waste (EHW), and organic/carbonaceous waste may be land treated provided that the owner/operator can demonstrate that effective treatment of dangerous waste constituents will occur, and at the end of the post-closure care period the owner/operator will be in compliance with subsection (4) of this section.
(6) Case-by-case exemptions to a land disposal prohibition. Any person may petition the department for an exemption from a prohibition in subsection (4) of this section for the land disposal of a dangerous waste. The procedures to submit a petition to the department are specified in WAC 173-303-910(6). The department may deny any petition if it determines that there is a potential for dangerous waste constituents to migrate from the land disposal facility where the waste is to be placed. The department will deny any petition when exemption would result in a substantial or imminent threat to public health or the environment. The department will deny any petition when exemption would result in a violation of applicable state laws.
The department may grant an exemption from the prohibitions and restrictions of subsection (4) of this section based on the demonstrations specified in (a), (b) or (c) of this subsection.
(a) Land disposal exemption for treatment residuals. Any person may request an exemption from a land disposal prohibition in subsection (4) of this section for treatment residuals by demonstrating to the department that:
(i) The person has applied the best achievable management method to the original waste; and
(ii) Application of additional management methods to the treatment residuals would prevent the person from utilizing the best achievable management methods for the original dangerous waste; and
(iii) The land disposal of the treatment residuals does not pose a greater risk to the public health and the environment than land disposal of the original dangerous waste would pose.
(b) Economic hardship exemption. Any person may request an exemption from a prohibition in subsection (4) of this section for the land disposal of a dangerous waste by demonstrating to the department that alternative management of the dangerous waste will impose an unreasonable economic burden in relation to the threat of harm to public health and the environment. It will be solely within the discretion of the department to approve or deny the requests for exemptions based on economic hardship.
(c) Organic/carbonaceous waste exemption. Any person may request an exemption from the requirements in subsection (4) of this section by demonstrating to the department that:
(i) Alternative management methods for organic/carbonaceous waste are less protective of public health and the environment than stabilization or landfilling; or
(ii)(A) The organic/carbonaceous waste has a heat content less than 3,000 BTU/LB or contains greater than sixty-five percent water or other noncombustible moisture; and
(B) Incineration is the only management method available within a radius of one thousand miles from Washington state's border (i.e., recycling or treatment are not available).
(7) Emergency cleanup provision. The department may, on a case-by-case basis, grant an exception to the land disposal restrictions in subsection (4) of this section for an emergency cleanup where an imminent threat to public health and the environment exists. Any exception will require compliance with applicable state law and will require (consistent with the nature of the emergency and imminent threat) application of the waste management priorities of RCW 70.105.150.

Treatment, storage, or disposal of dangerous waste.

(1) A person may offer, transport, transfer, or deliver a designated dangerous waste only to a TSD facility which is operating either: Under a permit issued pursuant to the requirements of this chapter; or, if the TSD facility is located outside of this state, under interim status or a permit issued by United States EPA under 40 C.F.R. Part 270, or under interim status or a permit issued by another state which has been authorized by United States EPA pursuant to 40 C.F.R. Part 271.
(2) A person may offer a state only designated dangerous waste (not regulated as a hazardous waste by EPA) to a facility which is located outside of this state and which does not meet the requirements of subsection (1) of this section if:
(a) The facility receiving the waste will legitimately treat or recycle the dangerous waste (disposal is an unacceptable management practice);
(b) The generator has on file a letter or copy of a letter signed by the regulatory authority in the receiving state that the receiving facility may accept the waste;
(c) The generator uses a transporter with a valid EPA/state identification number;
(d) The generator complies with all other applicable requirements, including manifesting, packaging and labeling, with respect to the shipping of the waste; and
(e) The generator receives from the receiving facility a signed and dated copy of the manifest.

Spills and discharges into the environment.

(1) Purpose and applicability. This section sets forth the requirements for any person responsible for a spill or discharge of a dangerous waste or hazardous substance into the environment, except when such release is otherwise permitted under state or federal law. For the purposes of complying with this section, a transporter who spills or discharges dangerous waste or hazardous substances during transportation will be considered the responsible person. This section applies when any dangerous waste or hazardous substance is intentionally or accidentally spilled or discharged into the environment (unless otherwise permitted) such that human health or the environment is threatened, regardless of the quantity of dangerous waste or hazardous substance.
(2) Notification. Any person who is responsible for a spill or nonpermitted discharge must immediately notify the individuals and authorities described for the following situations:
(a) For spills or discharges onto the ground or into groundwater or surface water, notify all local authorities in accordance with the local emergency plan. If necessary, check with the local emergency service coordinator and the fire department to determine all notification responsibilities under the local emergency plan. Also, notify the appropriate regional office of the department of ecology;
(b) For spills or discharges which result in emissions to the air, notify all local authorities in accordance with the local emergency plan. If necessary, check with the local emergency service coordinator and the fire department to determine all notification responsibilities under the local emergency plan. Also, in western Washington notify the local air pollution control authority; in eastern Washington notify the local air authority or the appropriate regional office of the department of ecology in those areas where there is no local authority.
(3) Mitigation and control. The person responsible for a spill or nonpermitted discharge must take appropriate immediate action to protect human health and the environment (e.g., diking to prevent contamination of state waters, shutting of open valves).
(a) In addition, the person responsible for a spill or discharge must:
(i) Clean up all released dangerous wastes or hazardous substances, or take such actions as may be required or approved by federal, state, or local officials acting within the scope of their official responsibilities. This may include complete or partial removal of released dangerous wastes or hazardous substances as may be justified by the nature of the released dangerous wastes or hazardous substances, the human and environmental circumstances of the incident, and protection required by the Water Pollution Control Act, chapter 90.48 RCW;
(ii) Designate and treat, store or dispose of all soils, waters, or other materials contaminated by the spill or discharge in accordance with this chapter 173-303 WAC. The department may require testing in order to determine the amount or extent of contaminated materials, and the appropriate designation, treatment, storage, or disposal for any materials resulting from cleanup; and
(iii) If the property on which the spill or discharge occurred is not owned or controlled by the person responsible for the incident, restore the area impacted by the spill or discharge, and replenish resources (e.g., fish, plants) in a manner acceptable to the department.
(b)(i) Where immediate removal, temporary storage, or treatment of spilled or discharged dangerous wastes or hazardous substances is necessary to protect human health or the environment, the department may direct persons to:
(A) Remove it without a manifest, by transporters who do not have EPA/state identification numbers;
(B) Temporarily store it at sites that are protective of human health and the environment and are secure from access by the public; and/or
(C) Treat it to reduce or control the hazards, under WAC 173-303-170.
(ii) When the department seeks to direct persons who are not responsible for a spill or discharge to carry out actions pursuant to this section, it will obtain their concurrence.

Division, dilution, and accumulation.

(1) Any action taken to evade the intent of this regulation by dividing or diluting wastes to change their designation shall be prohibited, except for the purposes of treating, neutralizing, or detoxifying such wastes.
(2) Separation of a homogeneous waste into heterogeneous phases (e.g., separation of a suspension into sludge and liquid phases, or of a solvent/water mixture into solvent and water phases, etc.) will not be considered as division, provided that the person generating the waste either:
(a) Designates the homogeneous waste before separation, and handles the entire waste accordingly; or
(b) Designates each phase of the heterogeneous waste, in accordance with the dangerous waste designation requirements of this chapter, and handles each phase accordingly.
(3) For the purposes of designation, quantities of continuously generated wastes must be summed monthly. All wastes generated less frequently than once a month will be considered as batch or single event wastes.

Containers.

(1) Waste quantity. Containers and inner liners will not be considered as a part of the waste when measuring or calculating the quantity of a dangerous waste. Only the weight of the residues in nonempty or nonrinsed containers or inner liners will be considered when determining waste quantities.
(2) A container or inner liner is "empty" when:
(a) All wastes in it have been taken out that can be removed using practices commonly employed to remove materials from that type of container or inner liner (for example, pouring, pumping, aspirating, etc.) and:
(i) No more than one inch of waste remains at the bottom of the container or inner liner; or
(ii) No more than 3 percent by weight of the total capacity of the container remains in the container or inner liner if the container is less than or equal to 119 gallons in size; or
(iii) No more than 0.3 percent by weight of the total capacity of the container remains in the container or inner liner if the container is greater than 119 gallons in size.
A container that held compressed gas is empty when the pressure inside the container equals or nearly equals atmospheric pressure; and
(b) If the container or inner liner held acutely hazardous waste, as defined in WAC 173-303-040, toxic EHW as defined in WAC 173-303-100 or pesticides bearing the danger or warning label, the container or inner liner has been rinsed at least three times with an appropriate cleaner or solvent. The volume of cleaner or solvent used for each rinsing must be ten percent or more of the container's or inner liner's capacity or of sufficient quantity to thoroughly decontaminate the container. In lieu of rinsing for containers that might be damaged or made unusable by rinsing with liquids (for example, fiber or cardboard containers without inner liners), an empty container may be vacuum cleaned, struck, with the open end of the container up, three times (for example, on the ground, with a hammer or hand) to remove or loosen particles from the inner walls and corners, and vacuum cleaned again. Equipment used for the vacuum cleaning of residues from containers or inner liners must be decontaminated before discarding, in accordance with procedures approved by the department. A container or inner liner is also considered "empty" if the container or inner liner has been cleaned by another method that has been shown in the scientific literature, or by tests conducted by the generator, to achieve equivalent removal.
Any rinsate or vacuumed residue that results from the cleaning of containers or inner liners must, whenever possible, be reused in a manner consistent with the original intended purpose of the substance in the container or inner liner. In the case of a farmer, if the rinsate is a pesticide residue then the rinsate must be managed or reused in a manner consistent with the application instructions on the pesticide label. On-site disposal or burial of pesticide residues is prohibited. Otherwise, the rinsate must be checked against the designation requirements (WAC 173-303-070 through 173-303-100) and, if designated, managed according to the requirements of this chapter.
(c) In the case of a container, the inner liner, that prevented the container from contact with the commercial chemical product or manufacturing chemical, has been removed.
(3)(a) Any residues remaining in containers or inner liners that are "empty" as described in subsection (2) of this section will not be subject to the requirements of this chapter, and will not be considered as accumulated wastes for the purposes of calculating waste quantities.
(b) Any dangerous waste in either: A container that is not empty, or an inner liner removed from a container that is not empty (as defined in subsection (2) of this section) is subject to the requirements of this chapter.
(4) A person who cannot meet the provisions in (2)(b) of this section may petition the department to approve alternative container rinsing processes in accordance with WAC 173-303-910(1).
(5) Containers of dangerous waste pharmaceuticals are subject to WAC 173-303-555(8) for determining when they are considered empty, in lieu of this section, except as provided by WAC 173-303-555 (8)(c) and (d).

Overpacked containers (labpacks).

Small containers of dangerous waste may be placed in overpacked drums (or labpacks) provided that the following conditions are met:
(1) Dangerous waste must be packaged in nonleaking inside containers. The inside containers must be of a design and constructed of a material that will not react dangerously with, be decomposed by, or be ignited by the contained waste. Inside containers must be tightly and securely sealed and, to the extent possible, should be full and have as little air as possible in them to minimize voids. The inside containers must be of the size and type specified in the Department of Transportation (DOT) hazardous materials regulations (49 C.F.R. Parts 173, 178, and 179), if those regulations specify a particular inside container for the waste;
(2) The inside containers must be overpacked in an open head DOT-specification drum shipping container which meets all of the requirements of 49 C.F.R. Parts 173, 178, and 179. The overpack container must not exceed a capacity of 416-liter (110 gallon). The overpack container must have a sufficient quantity of sorbent material to completely sorb all of the liquid contents of the inside containers. The sorbent in overpack containers to be placed in a landfill must be nonbiodegradable in accordance with WAC 173-303-140 (4)(b)(iv). The outer container must be full after it has been packed with inside containers and sorbent material;
(3) The sorbent material used must not be capable of reacting dangerously with, being decomposed by, or being ignited by the contents of the inside containers, in accordance with WAC 173-303-395 (1)(b);
(4) Incompatible wastes, as defined in WAC 173-303-040, must not be placed in the same outside container; and
(5) Reactive wastes, other than cyanide- or sulfide-bearing waste as defined in WAC 173-303-090 (7)(a)(v), must be treated or rendered nonreactive prior to packaging in accordance with subsections (1) through (4) of this section. Cyanide- and sulfide-bearing reactive waste may be packed in accordance with subsections (1) through (4) of this section without first being treated or rendered nonreactive.
(6) An itemized listing of the chemicals, their concentrations and quantities per labpack must be kept by the generator for five years and must be readily available in case of an emergency during shipment, and for the purposes of preparing annual reports under WAC 173-303-220.
(7) Such disposal is in compliance with the requirements of WAC 173-303-140 (2)(a). Persons who incinerate labpacks according to the requirements in 40 C.F.R. 268.42(c)(1) (incorporated by reference at WAC 173-303-140 (2)(a)) may use fiber drums in place of metal outer containers.

Quantity exclusion limits—Generator category determinations.

A generator must determine its generator category. A generator's category is based on the amount of dangerous waste generated each month and may change from month to month. This section sets forth procedures to determine whether a generator is a small quantity generator, a medium quantity generator, or a large quantity generator for a particular month, as defined in WAC 173-303-040.
(1) Quantity exclusion limits. In each of the designation sections describing the lists, characteristics, and criteria, quantity exclusion limits (QEL) are identified. The QEL is the quantity of dangerous waste generated in a calendar month used to distinguish when a dangerous waste is only subject to the small quantity generator provisions, the medium quantity generator provisions, or when a dangerous waste is subject to the large quantity generator provisions. Any solid waste (which is not excluded or exempted) that is listed, exhibits a characteristic, or meets the criteria of this chapter is a dangerous waste.
(2) Aggregated waste quantities.
(a) A person may be generating more than one kind of dangerous waste. In such cases, they must consider the aggregate quantity of their wastes when determining whether or not their waste amounts exceed the specific quantity exclusion limits (QEL) for waste generation;
(b) Waste quantities must be aggregated for all waste with common QELs. Example: If a person generates 100 pounds of an ignitable waste and 130 pounds of a persistent waste, then both wastes are regulated because the aggregate waste quantity (230 pounds) exceeds the common QEL of 220 pounds. On the other hand, if a person generates one pound of toxic EHW and 218 pounds of a corrosive waste, their quantities would not be aggregated because they do not share a common QEL (2.2 pounds and 220 pounds, respective QELs).
(3) Generator category determination.
(a) Determine separately the resulting generator categories for the quantities of waste with a 2.2 pound QEL and for the quantities of waste with a 220 pound QEL using Table 1 of this section; and
(b) Compare the resulting generator categories from (a) of this subsection and apply the more stringent generator category to the accumulation and management of dangerous waste with a 2.2 pound QEL and with a 220 pound QEL.
Table 1
Generator Categories Based on Quantity of Waste Generated in a Calendar Month
Quantity of dangerous waste with a QEL of 2.2 pounds generated in a calendar month
Quantity of dangerous waste with a QEL of 220 pounds generated in a calendar month
Quantity of residue or contaminated soil, water or other debris from a cleanup of a spill, into or on any land or water of any dangerous waste with a QEL of 2.2 pounds generated in a calendar month

Small quantity generator.
(4) When making the quantity determinations of this subsection and WAC 173-303-170 through 173-303-230, generators must include all dangerous wastes they generate, except dangerous waste that:
(a) Is exempt from regulation under WAC 173-303-071; or
(b) Is recycled under WAC 173-303-120 (2)(a), (3)(c) and (h), or (5); or
(c) Is managed in accordance with WAC 173-303-802(5) immediately upon generation only in on-site elementary neutralization units, wastewater treatment units, or totally enclosed treatment facilities as defined in WAC 173-303-040; or
(d) Is recycled, without prior storage or accumulation, only in an on-site process subject to regulation under WAC 173-303-120 (4)(a); or
(e) Is spent lead-acid batteries managed under the requirements of WAC 173-303-120 (3)(f) and 173-303-520; or
(f) Is universal waste managed under WAC 173-303-077 and 173-303-573; or
(g) Is a dangerous waste that is an unused commercial chemical product (listed in WAC 173-303-9903 or exhibits one or more characteristics or criteria listed in WAC 173-303-090 or 173-303-100) that is generated solely as a result of a laboratory clean-out conducted at an eligible academic entity pursuant to WAC 173-303-235(14). For purposes of this provision, the term eligible academic entity shall have the meaning as defined in WAC 173-303-235(1).
(h) (Reserved.)
(i) Is managed as part of an episodic event in compliance with the conditions of WAC 173-303-173.
(j) Is a dangerous waste pharmaceutical, as defined in WAC 173-303-555(1), that is managed in accordance with WAC 173-303-555 or is a dangerous waste pharmaceutical that is also a Drug Enforcement Administration controlled substance and managed under WAC 173-303-555(7). The total dangerous waste, including both dangerous waste pharmaceuticals and nonpharmaceutical dangerous waste, must be counted per WAC 173-303-170(10) for purposes of determining if a health care facility is subject to WAC 173-303-555.
(5) In determining the quantity of dangerous waste generated, a generator need not include:
(a) Dangerous waste when it is removed from on-site storage; or
(b) Spent materials that are generated, reclaimed, and subsequently reused on site, as long as such spent materials have been counted once (note: If after treatment or reclamation a residue is generated with a different waste code(s), that residue must be counted); or
(c) The container holding/containing the dangerous waste as described under WAC 173-303-160(1).
(6) Based on the generator category as determined under this section, the generator must meet the applicable independent requirements listed in WAC 173-303-170. A generator's category also determines which of the provisions of WAC 173-303-171, 173-303-172, 173-303-174 or 173-303-200 must be met to obtain an exemption from the storage facility permit, interim status, and operating requirements when accumulating dangerous waste.
(a) In a calendar month, if a small quantity generator generates more than the amounts specified in the definition of "small quantity generator" in WAC 173-303-040, the generator becomes subject to full requirements of a medium quantity generator or large quantity generator of this chapter, respectively, and cannot again be a small quantity generator until after all dangerous waste on site at the time they became fully regulated have been properly treated or disposed at a designated facility.
Example. If a person generates 4 pounds of an acute hazardous waste discarded chemical product (QEL 2.2 pounds) and 200 pounds of an ignitable waste (QEL 220 pounds), then both wastes are fully regulated, and the person is not a small quantity generator for either waste. "Fully regulated" in this example means the regulations applicable to a large quantity generator.
(b) In a calendar month if a medium quantity generator generates more than the amounts specified in the definition of "medium quantity generator" in WAC 173-303-040 the generator becomes subject to full requirements of a large quantity generator of this chapter, and cannot again be a medium quantity generator until after all dangerous waste on site at the time they became fully regulated have been properly treated or disposed at a designated facility.

Conditions for exemption for a medium quantity generator that accumulates dangerous waste.

A medium quantity generator, not to include transporters as referenced in WAC 173-303-240(3), may accumulate dangerous waste on site without a permit, interim status, and without complying with the requirements of WAC 173-303-600 provided that all the following conditions for exemption listed in this section are met. The special provisions of this section do not apply to acutely hazardous wastes or toxic EHW (WT01) that exceed the QEL that are being generated or accumulated by the generator.
(1) Off-site shipments. All dangerous waste is shipped off site to a designated facility or placed in an on-site facility which is permitted by the department under WAC 173-303-800 through 173-303-845 or recycled or treated on site in one hundred eighty days or less. A generator who accumulates dangerous waste for more than one hundred eighty days is an operator of a storage facility and is subject to the facility requirements of this chapter and the permit requirements of this chapter as a storage facility unless the generator has been granted an extension to the one hundred eighty-day period by the department as described in subsection (3) of this section.
(2) Generation. The generator generates in a calendar month no more than the amounts specified in the definition of "medium quantity generator" in WAC 173-303-040.
(3) Accumulation time limit. The generator accumulates dangerous waste on site for no more than one hundred eighty days unless the department has granted a maximum ninety-day extension to this one hundred eighty-day period. The department may, on a case-by-case basis, grant a maximum ninety-day extension to this one hundred eighty-day period if the generator must transport its waste, or offer its waste for transportation, over a distance of two hundred miles or more for off-site treatment, storage, or disposal and the dangerous wastes must remain on site due to unforeseen, temporary, and uncontrollable circumstances. For the purposes of this section, the one hundred eighty-day accumulation period begins on the date that:
(a) The generator first generates a dangerous waste; or
(b) The generator exceeds its satellite accumulation limits prescribed in WAC 173-303-174(1).
(4) Accumulation limit. The quantity of dangerous waste accumulated on site never exceeds the following limits at any one time:
(a) 6,600 Pounds of dangerous waste; or
(b) 2.2 Pounds of acutely hazardous waste or toxic EHW (WT01); or
(c) 220 Pounds of residues from a cleanup of acutely hazardous waste and/or toxic EHW (WT01).
(5) Accumulation of waste in containers.
(a) Condition of containers. If a container holding dangerous waste is not in good condition (e.g., severe corroding or rusting or flaking or scaling, and/or apparent structural defects) or if it begins to leak or is leaking, the generator must transfer the dangerous waste to a container that is in good condition and does not leak, and continue to manage that container and waste in compliance with the conditions for exemption of this section. In addition, the generator must address leaks and spills in accordance with the applicable provisions of WAC 173-303-145 and 173-303-360.

(c) Management of containers.
(i) A container holding dangerous waste must be closed at all times, except when it is necessary to add or remove waste.
(ii) A container holding dangerous waste must not be opened, handled, or stored in a manner which may rupture the container or cause it to leak.
(iii) A minimum thirty-inch aisle space separation is required between rows of containers. A row of containers must be no more than two wide and allow for unobstructed inspection of each container.
(d) Inspections. The generator must conduct "weekly inspections," as defined in WAC 173-303-040, of each central accumulation area looking for leaking containers and for deterioration of containers and the containment system caused by corrosion, deterioration, or other factors. The generator must keep a written or electronic inspection log including at least the date and time of the inspection, the printed name and the handwritten or electronic signature of the inspector, a notation of the observations made and the date and nature of any repairs or remedial actions taken. The log must be kept at the facility for at least five years from the date of inspection. The generator must take remedial action in accordance with (a) of this subsection if deterioration or leaks are detected.
(e) Secondary containment. For container accumulation the department requires that the central accumulation area(s) include secondary containment in accordance with WAC 173-303-630(7).
(f) Special requirements for ignitable or reactive waste.
(i) Containers holding reactive waste exhibiting a characteristic specified in WAC 173-303-090 (7)(a)(vi), (vii) or (viii) must be stored in a manner equivalent to the separation distances for storage of explosives in the International Fire Code, 2015 edition, or the version adopted by the local fire district.
(ii) The generator must design, operate, and maintain ignitable waste and reactive waste (other than a reactive waste which must meet (f)(i) of this subsection) container storage in a manner equivalent with the International Fire Code. Where no specific standard or requirements are specified in the International Fire Code, or in existing state or local fire codes, applicable sections of NFPA 30 "Flammable and Combustible Liquids Code," must be used. The generator must also comply with the requirements of WAC 173-303-395 (1)(d).
(g) Special requirements for incompatible wastes.
(i) Incompatible wastes, or incompatible wastes and materials must not be placed in the same container, unless WAC 173-303-395 (1)(b) is complied with.
(ii) Dangerous waste must not be placed in an unwashed container that previously held an incompatible waste or material.

Manifest.

A generator who transports, or offers for transport a dangerous waste for off-site treatment, storage, or disposal, or a treatment, storage, or disposal facility that offers for transport a rejected dangerous waste load, must follow all applicable procedures described in this section.
(1) Form and contents of dangerous waste manifests. 40 C.F.R. Part 262 Appendix - Uniform Hazardous Waste Manifest and Instructions (EPA Forms 8700-22 and 8700-22A and Their Instructions) is incorporated by reference. The manifest must be EPA Form 8700-22 and, if necessary, EPA Form 8700-22A. The manifest must be prepared in accordance with the instructions for these forms.
(a) A generator must designate on the manifest one facility that is permitted to handle the waste described on the manifest.
(b) A generator may also designate on the manifest one alternate facility that is permitted to handle their waste in the event an emergency prevents delivery of the waste to a primary designated facility.
(c) If the transporter is unable to deliver the dangerous waste to the designated facility or the alternate facility, the generator must either designate another facility or instruct the transporter to return the waste.
(2) The manifest must consist of enough copies to provide the generator, each transporter, and the designated facility owner/operator with a copy for their records, and another copy to be returned to the generator.
(3) Manifest procedures.
(a) The generator must:
(i) Sign and date the manifest certification by hand;
(ii) Obtain the handwritten signature of the initial transporter and date of acceptance on the manifest; and
(iii) Retain one copy in accordance with WAC 173-303-210, Generator recordkeeping.
(b) The generator must give the remaining manifest copies to the transporter.
(c) For shipments of dangerous waste within the United States solely by water (bulk shipments only), the generator must send three copies of the manifest dated and signed in accordance with this section to the owner or operator of the designated facility or the last water (bulk shipment) transporter to handle the waste in the United States if exported by water. Copies of the manifest are not required for each transporter.
(d) For rail shipments of dangerous waste within the United States which originate at the site of generation, the generator must send at least three copies of the manifest dated and signed in accordance with this section to:
(i) The next nonrail transporter, if any; or
(ii) The designated facility if transported solely by rail; or
(iii) The last rail transporter to handle the waste in the United States if exported by rail.
(e) For shipments of federally regulated hazardous waste to a designated facility in an authorized state which has not yet obtained authorization to regulate that particular waste as hazardous, the generator must assure that the designated facility agrees to sign and return the manifest to the generator, and that any out-of-state transporter signs and forwards the manifest to the designated facility.
(f) For rejected shipments of dangerous waste or container residues contained in nonempty containers that are returned to the generator by the designated facility (following the procedures of WAC 173-303-370 (5)(f)), the generator must:
(i) Sign either:
(A) Item 20 of the new manifest if a new manifest is used for the returned shipment; or
(B) Item 18c of the original manifest if the original manifest is used for the returned shipment.
(ii) Provide the transporter a copy of the manifest;
(iii) Within thirty days of delivery of the rejected shipment or container residues contained in nonempty containers, send a copy of the manifest to the designated facility that returned the shipment to the generator; and
(iv) Retain at the generator's site a copy of each manifest for at least three years from the date of delivery.
(4) Special requirements for shipments to the Washington EHW facility at Hanford.
(a) All generators planning to ship dangerous waste to the EHW facility at Hanford must notify the facility in writing and by sending a copy of the prepared manifest prior to shipment.
(b) The generator must not ship any dangerous waste without prior approval from the EHW facility. The state operator may exempt classes of waste from the requirements of WAC 173-303-180 (4)(a) and (b) where small quantities or multiple shipments of a previously approved waste are involved, or there exists an emergency and potential threat to public health and safety.
(5) The requirements of this section and WAC 173-303-190(2) do not apply to the transport of dangerous wastes on a public or private right of way within or along the border of contiguous property under the control of the same person, even if such contiguous property is divided by a public or private right of way: Provided, That ecology has approved an alternative paper tracking system that serves the purpose of a manifest. Notwithstanding WAC 173-303-240(2), the generator or transporter must comply with the requirements for transporters set forth in WAC 173-303-270 and 173-303-145 in the event of a discharge of dangerous waste on a public or private right of way.
(6) Special instructions for state-only dangerous waste that designates only by the criteria under WAC 173-303-100 and is not regulated as a hazardous waste under 40 C.F.R. Part 261 or as a hazardous material under the 49 C.F.R. hazardous material regulations. For purposes of completing the uniform hazardous waste manifest, Item 9b, and Item 28 if continuation sheet 8700-22A is used, or to describe a state-only dangerous waste on a shipping paper, the shipping description must include the following in sequence with no additional information interspersed:
(a) Material Not Regulated by DOT;
(b) Washington State Dangerous Waste Only followed by the appropriate criteria designation of the waste that is either toxic, persistent, solid corrosive or a combination of these entered in parentheses;
(c) Shipping description examples: Material Not Regulated by DOT (Washington State Dangerous Waste Only, Toxic); Material Not Regulated by DOT (Washington State Dangerous Waste Only, Toxic, Persistent); Material Not Regulated by DOT (Washington State Dangerous Waste Only, Solid Corrosive).
(7) Manifest tracking numbers, manifest printing, and obtaining manifests.
(a) 40 C.F.R. 262.21 (a) through (f) and (h) through (m) is incorporated by reference. EPA requirements for printing manifests for use or distribution are included in this section.
(b) A generator may use manifests printed by any source so long as the source of the printed form has received approval from EPA to print the manifest under paragraphs (c) and (e) of 40 C.F.R. 262.21. A registered source may be a:
(i) State agency;
(ii) Commercial printer;
(iii) Dangerous waste generator, transporter or TSDF; or
(iv) Dangerous waste broker or other preparer who prepares or arranges shipments of dangerous waste for transportation.
(c) A generator must determine whether the generator state or the consignment state for a shipment regulates any additional wastes (beyond those regulated federally) as hazardous wastes under these states' authorized programs. Generators also must determine whether the consignment state or generator state requires the generator to submit any copies of the manifest to these states. In cases where the generator must supply copies to either the generator's state or the consignment state, the generator is responsible for supplying legible photocopies of the manifest to these states.
(8) Waste minimization certification. A generator who initiates a shipment of dangerous waste must certify to one of the following statements in Item 15 of the uniform hazardous waste manifest:
(a) "I am a large quantity generator. I have a program in place to reduce the volume and toxicity of waste generated to the degree I have determined to be economically practicable and I have selected the practicable method of treatment, storage, or disposal currently available to me which minimizes the present and future threat to human health and the environment"; or
(b) "I am a medium quantity generator. I have made a good faith effort to minimize my waste generation and select the best waste management method that is available to me and that I can afford." Note that a Washington state medium quantity generator regulated under WAC 173-303-172 is the type of generator referred to where the manifest states "(b) if I am a small quantity generator", due to the different term used by EPA.
(9) Use of electronic manifest. In lieu of using the manifest form specified in subsection (1) of this section, a person may prepare and use an electronic manifest, provided that the person:
(a) Complies with the requirements of 40 C.F.R. Part 3.10 for the reporting of electronic documents to EPA; and
(b) Complies with the requirements in subsections (10) and (11) of this section.
(10) Legal equivalence to paper manifests.
(a) Electronic manifests that are obtained, completed, and transmitted in accordance with subsection (9) of this section and used in accordance with this section are the legal equivalent of paper manifest forms bearing handwritten signatures, and satisfy for all purposes any requirement in this section to obtain, complete, sign, provide, use or retain a manifest.
(i) Any requirement in this section to sign a manifest or manifest certification by hand, or to obtain a handwritten signature, is satisfied by signing with or obtaining a valid and enforceable electronic signature within the meaning of subsection (11) of this section.
(ii) Any requirement in this section to give, provide, send, forward, or return to another person a copy of the manifest is satisfied when an electronic manifest is transmitted to the other person by submission to the e-Manifest system.
(iii) Any requirement in this section for a generator to keep or retain a copy of each manifest is satisfied by retention of a signed electronic manifest in the generator's account on the national e-Manifest system, provided that such copies are readily available for viewing and production upon request.
(iv) A generator may not be held liable for the inability to produce an electronic manifest for inspection under this section if the generator can demonstrate that the inability to produce the electronic manifest is due exclusively to a technical difficulty with the electronic manifest system for which the generator bears no responsibility.
(b) A generator may participate in the electronic manifest system either by accessing the electronic manifest system from its own electronic equipment, or by accessing the electronic manifest system from portable equipment brought to the generator's site by the transporter who accepts the dangerous waste shipment from the generator for off-site transportation.
(c)(i) Restriction on use of electronic manifests. A generator may prepare an electronic manifest for the tracking of dangerous waste shipments involving any dangerous waste only if it is known at the time the manifest is originated that all waste handlers named on the manifest participate in the electronic manifest system, except that:
(ii) A generator may sign by hand and retain a paper copy of the manifest signed by hand by the initial transporter, in lieu of executing the generator copy electronically, thereby enabling the transporter and subsequent waste handlers to execute the remainder of the manifest copies electronically.
(d) Requirement for one printed copy. To the extent the hazardous materials regulation on shipping papers for carriage by public highway requires shippers of hazardous material to supply a paper document for compliance with 49 C.F.R. Part 177.817, a generator originating an electronic manifest must also provide the initial transporter with one printed copy of the electronic manifest. In addition, the one printed copy of the electronic manifest must provide the information required in subsection (6) of this section for state-only dangerous waste that designates only by the criteria under WAC 173-303-100 and as state listed WPCB and WSC2.
(e) Special procedures when electronic manifest is unavailable. If a generator has prepared an electronic manifest for a dangerous waste shipment, but the electronic manifest system becomes unavailable for any reason prior to the time that the initial transporter has signed electronically to acknowledge the receipt of the dangerous waste from the generator, then the generator must obtain and complete a paper manifest (EPA form 8700-22) and if necessary, a continuation sheet (EPA form 8700-22A) in accordance with the manifest instructions and use these paper forms from this point forward in compliance with subsections (1) through (8) of this section from this point forward.
(f) Special procedures for electronic signature methods undergoing tests. If a generator has prepared an electronic manifest for a dangerous waste shipment, and signs this manifest electronically using an electronic signature method which is undergoing pilot or demonstration tests aimed at demonstrating the practicality or legal dependability of this signature method, then the generator shall also sign with an ink signature the generator/offeror certification on the printed copy of the manifest provided under (d) of this subsection.
(g) Imposition of user fee. A generator who is a user of the electronic manifest may be assessed a user fee by EPA for the origination of each electronic manifest. EPA shall maintain and update from time-to-time the current schedule of electronic manifest user fees, which shall be determined based on current and projected system costs and level of use of the electronic manifest system. The current schedule of electronic manifest user fees will be published by EPA as an appendix to 40 C.F.R. Part 262.
(h) Post-receipt manifest data corrections. After facilities have certified to the receipt of dangerous waste by signing Item 20 of the manifest, any post-receipt data corrections may be submitted at any time by any interested person (e.g., waste handler) named on the manifest. Generators may participate electronically in the post-receipt data corrections process by following the process described in WAC 173-303-370 (10)(g), which applies to corrections made to either paper or electronic manifest records.
(11) Electronic manifest signatures. Electronic signature methods for the e-Manifest system shall:
(a) Be a legally valid and enforceable signature applicable under state, EPA and other federal requirements pertaining to electronic signatures; and
(b) Be a method that is designed and implemented in a manner that EPA considers to be as cost-effective and practical as possible for the users of the manifest.

Conditions for exemption for a large quantity generator that accumulates dangerous waste.

Large quantity generators, not to include transporters as referenced in WAC 173-303-240(3), may accumulate dangerous waste on site without a permit or interim status, and without complying with the requirements of WAC 173-303-600 provided that all of the following conditions for exemption listed in this section are met.
(1) Off-site shipments. All dangerous waste is shipped off site to a designated facility or placed in an on-site facility which is permitted by the department under WAC 173-303-800 through 173-303-845 or recycled or treated on site in ninety days or less. A generator who accumulates dangerous waste for more than ninety days is an operator of a storage facility and is subject to the facility requirements of this chapter and the permit requirements of this chapter as a storage facility unless they have been granted an extension to the ninety-day period allowed pursuant to subsection (2) of this section;
(2) Accumulation time limit.
(a) The generator accumulates dangerous waste on site for no more than ninety days unless;
(i) The department has granted a maximum thirty-day extension to this ninety-day period. The department may, on a case-by-case basis, grant a maximum thirty-day extension to this ninety-day period if dangerous waste must remain on site due to unforeseen, temporary and uncontrollable circumstances; or
(ii) The F006 accumulation conditions for exemption in subsection (13) of this section are met.
(b) For the purposes of this section, the ninety-day accumulation period begins on the date that:
(i) The generator first generates a dangerous waste; or
(ii) The quantity (or aggregated quantity) of dangerous waste being accumulated by a small quantity generator first exceeds the accumulation limit for such waste (or wastes); or
(iii) The generator exceeds its satellite accumulation limits prescribed in WAC 173-303-174(1).
(3) Accumulation of waste in containers.
(a) Condition of containers. If a container holding dangerous waste is not in good condition (e.g., severe corroding or rusting or flaking or scaling, and/or apparent structural defects) or if it begins to leak or is leaking, the generator must transfer the dangerous waste from this container to a container that is in good condition and does not leak and continue to manage that container and waste in compliance with the conditions for exemption in this section. In addition, the generator must address leaks and spills in accordance with the applicable provisions of WAC 173-303-145 and 173-303-201(14).
(b) Compatibility of waste with container. The generator must use a container made of or lined with materials which will not react with, and are otherwise compatible with, the dangerous waste to be stored, so that the ability of the container to contain the waste is not impaired.
(c) Management of containers.
(i) A container holding dangerous waste must be closed at all times, except when it is necessary to add or remove waste.
(ii) A container holding dangerous waste must not be opened, handled, or stored in a manner which may rupture the container or cause it to leak.
(iii) A minimum thirty-inch aisle space separation is required between rows of containers. A row of containers must be no more than two wide and allow for unobstructed inspection of each container.
(d) Inspections. The generator must conduct "weekly inspections," as defined in WAC 173-303-040, of each central accumulation area looking for leaking containers and for deterioration of containers and the containment system caused by corrosion, deterioration, or other factors. The generator must keep a written or electronic inspection log including at least the date and time of the inspection, the printed name and the handwritten or electronic signature of the inspector, a notation of the observations made and the date and nature of any repairs or remedial actions taken. The log must be kept at the facility for at least five years from the date of inspection. See subsection (3)(a) of this section for remedial action required if deterioration or leaks are detected.
(e) Secondary containment. For container accumulation the department requires that the central accumulation area(s) must include secondary containment in accordance with WAC 173-303-630(7).
(f) Special requirements for ignitable or reactive waste.
(i) Containers holding reactive waste exhibiting a characteristic specified in WAC 173-303-090 (7)(a)(vi), (vii) or (viii) must be stored in a manner equivalent to the separation distance for storage of explosives in the International Fire Code, 2015 edition, or the version adopted by the local fire district.
(ii) The generator must design, operate, and maintain ignitable waste and reactive waste (other than a reactive waste which must meet (f)(i) of this subsection) container storage in a manner equivalent with the International Fire Code. Where no specific standard or requirements are specified in the International Fire Code, or in existing state or local fire codes, applicable sections of NFPA 30 "Flammable and Combustible Liquids Code," must be used. The generator must also comply with the requirements of WAC 173-303-395 (1)(d).
(iii) The generator must take precautions to prevent accidental ignition or reaction of ignitable or reactive waste. This waste must be separated and protected from sources of ignition or reaction including, but not limited to, the following: Frictional heat, sparks (static, electrical, or mechanical), and radiant heat. While ignitable or reactive waste is being handled, the generator must confine smoking and open flame to specially designated locations. "No Smoking" signs must be conspicuously place wherever there is a hazard from ignitable or reactive waste.
(g) Special requirements for incompatible wastes.
(i) Incompatible waste, or incompatible wastes and materials must not be placed in the same container, unless WAC 173-303-395 (1)(b) is complied with.
(ii) Dangerous waste must not be placed in an unwashed container that previously held an incompatible waste or material.
(iii) A storage container holding a dangerous waste that is incompatible with any waste or other materials stored nearby in other containers, piles, open tanks, or surface impoundments must be separated from the other materials or protected from them by means of a dike, berm, wall, or other device. Containment systems for incompatible wastes must be separate.
(h) Closure.
(i) At closure, all dangerous waste and dangerous waste residues must be removed from the containment system. Remaining containers, liners, base, and soil containing or contaminated with dangerous waste or dangerous waste residues must be decontaminated or removed.
(ii) In addition, such a generator is exempt from all the requirements in WAC 173-303-610 and 173-303-620, except for WAC 173-303-610 (2) and (5).
(i) Air emission standards. The generator must comply with the applicable requirements of 40 C.F.R. Part 265, Subparts AA, BB, and CC incorporated by reference in WAC 173-303-400 (3)(a).
(4) Accumulation of dangerous waste in tanks. The generator must comply with:
(a) Applicable air emission standards of 40 C.F.R. Part 265, Subparts AA, BB, and CC incorporated by reference in WAC 173-303-400 (3)(a); and
(b) Tank standards of WAC 173-303-640 (2) through (10), except WAC 173-303-640 (8)(c) and the second sentence of WAC 173-303-640 (8)(a). (Note: A generator, unless otherwise required to do so, does not have to prepare a closure plan, a cost estimate for closure, or provide financial responsibility of their tank system to satisfy the requirement of this section.) Such a generator is exempt from the requirements of WAC 173-303-620 and 173-303-610, except for WAC 173-303-610 (2) and (5).
(5) Accumulation of hazardous waste on drip pads. If the waste is placed on drip pads, the generator must comply with the following:
(a) WAC 173-303-675; and
(b) Remove all wastes from the drip pad and associated collection systems at least once every ninety days; and
(c) Waste removed from drip pads and associated collection systems must be sent immediately to:
(i) An off-site designated facility; or
(ii) An on-site permitted facility; or
(iii) To an on-site central accumulation area where the waste is managed in compliance with the on-site central accumulation area regulations in this section for the remainder of the ninety-day accumulation time limit for large quantity generators. (Example: A generator removes waste from the drip pad at fifty days, and the generator is then allowed to further accumulate that waste in its central accumulation area for up to an additional forty days.);
(d) Maintain the following records on site and readily available for inspection:
(i) The original start date waste was first placed on, or began to accumulate on, the drip pad;
(ii) A description of procedures that will be followed to ensure that all wastes are removed from the drip pad and associated collection systems at least once every ninety days; and
(iii) Documentation of each waste removal, including the quantity of waste removed from the drip pad and the sump or collection system and the date and time of removal.
(6) Accumulation of hazardous waste in containment buildings. If the waste is placed in containment buildings, the generator must comply with the following:
(a) 40 C.F.R. Part 265, Subpart DD, which is incorporated by reference; and
(b) Labeling.

Preparedness, prevention, emergency procedures and contingency plans for large quantity generators.

(1) Applicability. The regulations of this section apply to those areas of a large quantity generator's facility where dangerous waste is generated or accumulated on site.
(2) A large quantity generator facility must be designed, constructed, maintained and operated to minimize the possibility of fire, explosion, or any unplanned sudden or nonsudden release of dangerous waste, hazardous substance or dangerous waste constituents to air, soil, or surface or groundwater which could threaten the public health or the environment. This section describes preparations and preventive measures which help avoid or mitigate such situations.
(3) Required equipment. All areas deemed applicable by subsection (1) of this section must be equipped with the following, unless it can be demonstrated to the department that none of the hazards posed by waste or hazardous substance handled at the facility could require a particular kind of equipment specified below. A large quantity generator may determine the most appropriate locations within its facility to locate equipment necessary to prepare for and respond to emergencies:
(a) An internal communications or alarm system capable of providing immediate emergency instruction (voice or signal) to facility personnel;
(b) A device, such as a telephone (immediately available at the scene of operations) or a hand-held, two-way radio, capable of summoning emergency assistance from local police departments, fire departments, or state or local emergency response teams;
(c) Portable fire extinguishers, fire control equipment (including special extinguishing equipment, such as those using foam, inert gas, or dry chemicals), spill control equipment, and decontamination equipment; and
(d) Water at adequate volume and pressure to supply water hose streams, foam producing equipment, automatic sprinklers, or water spray systems.
(4) Testing and maintenance of equipment. All facility communications or alarm systems, fire protection equipment, spill control equipment, and decontamination equipment, where required, must be tested and maintained as necessary to assure its proper operation in time of emergency.
(5) Access to communications or alarms. Personnel must have immediate access to the signaling devices described in the situations below:
(a) Whenever dangerous waste is being poured, mixed, spread, or otherwise handled, all personnel involved must have immediate access (e.g., direct or unimpeded access) to an internal alarm or emergency communication device, either directly or through visual or voice contact with another employee, unless such a device is not required in subsection (3) of this section;
(b) If there is ever just one employee on the premises while the facility is operating, they must have immediate access (e.g., direct or unimpeded access) to a device, such as a telephone (immediately available at the scene of operation) or a hand-held, two-way radio, capable of summoning external emergency assistance, unless such a device is not required in subsection (3) of this section.
(6) Aisle space. The generator must maintain aisle space to allow the unobstructed movement of personnel, fire protection equipment, spill control equipment, and decontamination equipment to any area of facility operation in an emergency, unless it can be demonstrated to the department that aisle space is not needed for any of these purposes.
(7) Arrangements with local authorities. The large quantity generator must attempt to make the following arrangements, as appropriate for the type of waste handled at its facility and the potential need for the services of these organizations, unless the hazards posed by wastes handled at the facility would not require these arrangements:
(a) Arrangements to familiarize police, fire departments, and emergency response teams with the layout of the facility, properties of dangerous waste handled at the facility and associated hazards, places where facility personnel would normally be working, entrances to and roads inside the facility, and possible evacuation routes;
(b) Arrangements to familiarize local hospitals with the properties of dangerous waste handled at the facility and the types of injuries or illnesses which could result from fires, explosions, or releases at the facility;
(c) Agreements with state emergency response teams, emergency response contractors, and equipment suppliers;
(d) Where more than one party might respond to an emergency, agreements designating primary emergency authority and agreements with any others to provide support to the primary emergency authority;
(e) Where state or local authorities decline to enter into such arrangements, the generator must document the refusal in the operating record; and
(f) A facility possessing twenty-four-hour response capabilities may seek a waiver from the authority having jurisdiction (AHJ) over the fire code with the facility's locality as far as needing to make arrangements with the local fire department as well as any other organization necessary to respond to an emergency, provided that the waiver is documented in the generator's operating record.
(8) Contingency plan purpose and implementation.
(a) The large quantity generator must have a contingency plan for the facility. The purpose of a contingency plan and emergency procedures is to lessen the potential impact on the public health and the environment due to any emergency event such as, but not limited to, a fire, natural disaster, explosion, or any unplanned sudden or nonsudden release of dangerous waste, hazardous substance or dangerous waste constituents to air, soil, surface water, or groundwater.
(b) A contingency plan must be developed to lessen the potential impacts of such emergency events, and the plan must be implemented immediately when such emergency events occur.
(9) Contents of a contingency plan.
(a) Each large quantity generator must have a contingency plan at their facility for use in emergencies or any sudden or nonsudden releases which threaten human health and the environment. If the generator has already prepared a spill prevention control and countermeasures (SPCC) plan in accordance with 40 C.F.R. Part 112, or some other emergency or contingency plan, they need only amend that plan to incorporate dangerous waste management provisions that are sufficient to comply with the requirements of this section. The large quantity generator may develop one contingency plan that meets all regulatory requirements. Ecology recommends that the plan be based on the National Response Team's Integrated Contingency Plan Guidance ("One Plan").
(b) The contingency plan must contain the following:

Alternative requirements for eligible academic laboratories.

(1) The following definitions apply to this section:
(a) "College/university" means a private or public, postsecondary, degree-granting, academic institution, that is accredited by an accrediting agency listed annually by the U.S. Department of Education.
(b) "Eligible academic entity" means a college or university, or a nonprofit research institute that is owned by or has a formal written affiliation agreement with a college or university, or a teaching hospital that is owned by or has a formal written affiliation agreement with a college or university.
(c) "Formal written affiliation agreement" for a nonprofit research institute means a written document that establishes a relationship between institutions for the purposes of research and/or education and is signed by authorized representatives from each institution. A relationship on a project-by-project or grant-by-grant basis is not considered a formal written affiliation agreement. A formal written affiliation agreement for a teaching hospital means a master affiliation agreement and program letter of agreement, as defined by the Accreditation Council for Graduate Medical Education, with an accredited medical program or medical school.
(d) "Laboratory" means an area owned by an eligible academic entity where relatively small quantities of chemicals and other substances are used on a nonproduction basis for teaching or research (or diagnostic purposes at a teaching hospital) and are stored and used in containers that are easily manipulated by one person. Photo laboratories, art studios, and field laboratories are considered laboratories. Areas such as chemical stockrooms and preparatory laboratories that provide a support function to teaching or research laboratories (or diagnostic laboratories at teaching hospitals) are also considered laboratories.
(e) "Laboratory clean-out" means an evaluation of the inventory of chemicals and other materials in a laboratory that are no longer needed or that have expired and the subsequent removal of those chemicals or other unwanted materials from the laboratory. A clean-out may occur for several reasons. It may be on a routine basis (e.g., at the end of a semester or academic year) or as a result of a renovation, relocation, or change in laboratory supervisor/occupant. A regularly scheduled removal of unwanted material as required by subsection (9) of this section does not qualify as a laboratory clean-out.
(f) "Laboratory worker" means a person who handles chemicals and/or unwanted material in a laboratory and may include, but is not limited to, faculty, staff, postdoctoral fellows, interns, researchers, technicians, supervisors/managers, and principal investigators. A person does not need to be paid or otherwise compensated for their work in the laboratory to be considered a laboratory worker. Undergraduate and graduate students in a supervised classroom setting are not laboratory workers.
(g) "Nonprofit research institute" means an organization that conducts research as its primary function and files as a nonprofit organization under the tax code of 26 U.S.C. 501(c)(3).

Washington registration is not required for a transporter whose activities are limited to passing through Washington with shipments of dangerous waste or picking up shipments from Washington generators or delivering shipments to designated treatment, storage or disposal facilities. In order to obtain registration, a transporter must complete a Dangerous Waste Site Identification Form according to the instructions and submit it to the department;
(b) Maintains ten-day storage records that include the dates that a manifested shipment of dangerous waste entered the facility and departed the facility. The ten-day records must be retained for a period of three years from the date the shipment was transported from the transfer facility;
(c) WAC 173-303-310 (1) and (2) (Security). Instead of WAC 173-303-310(2) for an enclosed or an open flatbed transport vehicle parked at a transfer facility that has no twenty-four-hour surveillance system or natural or artificial barrier, the transport vehicle must meet the placarding requirements of 49 C.F.R. Part 172 and be secured (that is, locked) or the shipment must be transferred to a secured area of the facility to prevent unknowing entry and minimize unauthorized entry;
(d) WAC 173-303-320 General inspection. Instead of keeping inspection records for a period of five years from the date of inspection in WAC 173-303-320 (2)(d), inspection records must be kept at the transfer facility for one year from the date of inspection;
(e) WAC 173-303-330 Personnel training;
(f) WAC 173-303-340 Preparedness and prevention except WAC 173-303-340(3) (Aisle space);
(g) WAC 173-303-350 Contingency plan and emergency procedures;
(h) WAC 173-303-360 Emergencies;
(i) WAC 173-303-630 (2), (3), (4), (5)(a) and (b), (8), (9)(a) and (b) and (10) (Use and management of containers). In addition, when consolidating the contents of two or more containers with the same dangerous waste into a container, or when combining and consolidating two different dangerous wastes that are compatible with each other, the transporter must label or mark each container in accordance with WAC 173-303-630(3) and with the applicable dangerous waste number(s) (dangerous waste codes);
(j) WAC 173-303-630(7) in areas where waste is transferred from container to container and in areas where containers are stored outside in the weather. The secondary containment system must be completed by October 15, 2001. The department may, on a case-by-case basis, grant an extension to the required completion date if the transporter has a design and has entered into binding financial or other agreements for construction prior to October 15, 2001;
(k) The requirements of WAC 173-303-630(7) may be required in areas other than those described in WAC 173-303-240 (6)(j) if the department determines that there is a potential threat to public health and the environment due to the nature of the wastes being stored or due to a history of spills or releases from waste stored in containers.
(7) Transporter exemptions. A transporter will not be required to comply with the following:
(a) The requirements of WAC 173-303-240(6) in the event of an emergency or other unforeseen event beyond the reasonable control of the transporter during transit over public highway, rail track or water route and the waste shipment is loaded, reloaded or transferred to another transport vehicle or container to facilitate transportation;
(b) The requirements of WAC 173-303-240 (6)(i) and (j) for dangerous waste that is stored in a secured, enclosed transport vehicle, intermodal container or portable tank during the time it is parked at a transfer facility;

Part 176, and accepted by the approval authority of the United States Coast Guard;
(d) The requirements of WAC 173-303-240 (6)(j) for dangerous waste that is stored within a building: Provided, That the floor is compatible with and sufficiently impervious to the waste stored and is designed and operated so that any release or spill will be captured within the building and will prevent any waste from migrating to the soil, groundwater or surface water.
(8) A transporter who accumulates or stores manifested shipments of dangerous waste for more than ten days at a transfer facility is subject to the dangerous waste management facility general requirements and permit requirements of this chapter with respect to the storage of those wastes.
(9) Reference to WAC 173-303-200 in 173-303-240(4) does not constitute authority for storage in excess of ten days for a transporter who owns or leases and operates a transfer facility.
(10) The regulations in WAC 173-303-250 through 173-303-260 do not apply to transportation during an explosives or munitions emergency response, conducted in accordance with WAC 173-303-400 (2)(c)(xiii)(A)(IV) or (xiii)(D) or WAC 173-303-600 (3)(p)(i)(D) or (3)(p)(iv), and WAC 173-303-800 (7)(c)(i)(C) or (D).
(11) A transporter of hazardous waste subject to the manifesting requirements of WAC 173-303-180 or to the universal waste management standards of WAC 173-303-573, that is being imported from or exported to any other country for purposes of recovery or disposal is subject to this section and to all other relevant requirements of 40 C.F.R. Subpart H of Part 262 including, but not limited to, 40 C.F.R. 262.83 and 262.84 for movement documents. 40 C.F.R. Subpart H is incorporated by reference at WAC 173-303-230(1).

Dangerous waste acceptance, transport, and delivery.

(1)(a) A transporter may not accept dangerous waste from a generator unless the transporter is also provided with a manifest signed in accordance with WAC 173-303-180(3) (Manifest procedures) or is provided with an electronic manifest that is obtained, completed, and transmitted in accordance with WAC 173-303-180(9) and signed with a valid and enforceable electronic signature as described in WAC 173-303-180(11).
(b) Exports. For exports of dangerous waste subject to 40 C.F.R. 262 Subpart H (which is incorporated by reference at WAC 173-303-230(1)), a transporter may not accept such waste without a manifest signed by the generator in accordance with this section, as appropriate, and for exports occurring under the terms of a consent issued by EPA on or after December 31, 2016, a movement document that includes all information required by 40 C.F.R. Part 262.83(d).
(2) Before transporting a dangerous waste shipment, the transporter must sign and date the manifest, acknowledging acceptance of the dangerous waste. The transporter must return a signed copy to the generator before commencing transport.
(3) The transporter must insure that the manifest accompanies the dangerous waste shipment. In the case of exports occurring under the terms of a consent issued by EPA to the exporter on or after December 31, 2016, the transporter must ensure that a movement document that includes all information required by 40 C.F.R. Part 262.83(d) also accompanies the dangerous waste. In the case of imports occurring under the terms of a consent issued by EPA to the country of export or the importer on or after December 31, 2016, the transporter must ensure that a movement document that includes all information required by 40 C.F.R. Part 262.84(d) also accompanies the dangerous waste.
(4) A transporter who delivers a dangerous waste to another transporter, or to the designated facility must:
(a) Obtain the date of delivery and the handwritten signature of that transporter or designated facility owner/operator on the manifest;
(b) Retain one copy of the manifest in accordance with WAC 173-303-260, Transporter recordkeeping; and
(c) Give the remaining copies of the manifest to the accepting transporter or designated facility.
(5) Except as provided in subsection (6) of this section, the transporter must deliver the entire quantity of dangerous waste which they have accepted from a generator or a transporter to:
(a) The designated facility listed on the manifest; or
(b) The alternate designated facility, if the dangerous waste cannot be delivered to the designated facility because an emergency prevents delivery; or
(c) The next designated transporter; or
(d) The place outside the United States designated by the generator.
(6)(a) Emergency condition. If the dangerous waste cannot be delivered in accordance with subsection (5)(a), (b) and (d) of this section because of an emergency condition other than rejection of the waste by the designated facility, or alternate designated facility, then the transporter must contact the generator for further directions and must revise the manifest according to the generator's instructions.
(b) Transporters without generator authority. If the dangerous waste is not delivered to the next designated transporter in accordance with subsection (5)(c) of this section, and the current transporter is without contractual authorization from the generator to act as the generator's agent with respect to transporter additions or substitutions, then the current transporter must contact the generator for further instructions prior to making any revisions to the transporter designations on the manifest. The current transporter may thereafter make such revisions if:
(i) The dangerous waste is not delivered in accordance with subsection (5)(c) of this section because of an emergency condition; or
(ii) The current transporter proposes to change the transporter(s) designated on the manifest by the generator, or to add a new transporter during transportation, to respond to an emergency, or for purposes of transportation efficiency, convenience, or safety; and
(iii) The generator authorizes the revision.
(c) Transporters with generator authorization. If the dangerous waste is not delivered to the next designated transporter in accordance with subsection (5)(c) of this section, and the current transporter has authorization from the generator to act as the generator's agent, then the current transporter may change the transporters(s) designated on the manifest, or add a new transporter, during transportation without the generator's prior, explicit approval, provided that:
(i) The current transporter is authorized by a contractual provision that provides explicit agency authority for the transporter to make such transporter changes on behalf of the generator;
(ii) The transporter enters in Item 14 of each manifest for which such a change is made, the following statement of its agency authority: "Contract retained by generator confers agency authority on initial transporter to add or substitute additional transporters on generator's behalf"; and
(iii) The change in designated transporters is necessary to respond to an emergency, or for purposes of transportation efficiency, convenience, or safety.
(d) Generator liability. The grant by the generator of authority to a transporter to act as the agent of the generator with respect to changes to transporter designations under (c) of this subsection does not affect the generator's liability or responsibility for complying with any applicable requirement under this chapter, or grant any additional authority to the transporter to act on behalf of the generator.
(e) Rejected loads. If dangerous waste is rejected by the designated facility while the transporter is on the facility's premises, then the transporter must obtain the following:
(i) For a partial load rejection or for regulated quantities of container residues, a copy of the original manifest that includes the facility's date and signature, and the manifest tracking number of the new manifest that will accompany the shipment, and a description of the partial rejection or container residue in the discrepancy block of the original manifest. The transporter must retain a copy of this manifest in accordance with WAC 173-303-260, and give the remaining copies of the original manifest to the rejecting designated facility. If the transporter is forwarding the rejected part of the shipment or a regulated container residue to an alternate facility or returning it to the generator, the transporter must obtain a new manifest to accompany the shipment, and the new manifest must include all of the information required in WAC 173-303-370 (5)(e)(i) through (vi) or 173-303-370 (5)(f)(i) through (vi).
(ii) For a full load rejection that will be taken back by the transporter, a copy of the original manifest that includes the rejecting facility's signature and date attesting to the rejection, the description of the rejection in the discrepancy block of the manifest, and the name, address, phone number, and identification number for the alternate facility or generator to whom the shipment must be delivered. The transporter must retain a copy of the manifest in accordance with WAC 173-303-260, and give a copy of the manifest containing this information to the rejecting designated facility. If the original manifest is not used, then the transporter must obtain a new manifest for the shipment and comply with WAC 173-303-370 (5)(e)(i) through (vi).
(7) The requirements of subsections (3), (4), and (8) of this section do not apply to water (bulk shipment) transporters if:
(a) The dangerous waste is delivered by water (bulk shipment) to the designated facility; and
(b) A shipping paper containing all the information required on the manifest (excluding the EPA/state identification numbers, generator certification, and signatures) and, for exports or imports occurring under the terms of a consent issued by EPA on or after December 31, 2016, a movement document that includes all information required by 40 C.F.R. part 262.83(d) or 262.84(d) accompanies the dangerous waste; and
(c) The delivering transporter obtains the date of delivery and handwritten signature of the owner or operator of the designated facility on either the manifest or the shipping paper; and
(d) The person delivering the dangerous waste to the initial water (bulk shipment) transporter obtains the date of delivery and signature of the water (bulk shipment) transporter on the manifest and forwards it to the designated facility; and
(e) A copy of the shipping paper or manifest is retained by each water (bulk shipment) transporter in accordance with WAC 173-303-260(2).
(8) For shipments involving rail transportation, the requirements of subsections (3), (4), and (7) of this section do not apply and the following requirements do apply.
(a) When accepting dangerous waste from a nonrail transporter, the initial rail transporter must:
(i) Sign and date the manifest acknowledging acceptance of the dangerous waste;
(ii) Return a signed copy of the manifest to the nonrail transporter;
(iii) Forward at least three copies of the manifest to:
(A) The next nonrail transporter, if any; or

(ii) For shipments initiated prior to the automated export system (AES) filing compliance date, when instructed by the exporter to do so, give a copy of the manifest to a U.S. Customs official at the point of departure from the United States.
(10) Use of electronic manifest.
(a) Legal equivalence to paper forms for participating transporters. Electronic manifests that are obtained, completed, and transmitted in accordance with WAC 173-303-180(9) and used in accordance with this section are the legal equivalent of paper manifest forms bearing handwritten signatures, and satisfy for all purposes any requirement in this section to obtain, complete, sign, provide, give, use or retain a manifest.
(i) Any requirement in this section to sign a manifest or manifest certification by hand, or to obtain a handwritten signature, is satisfied by signing with or obtaining a valid and enforceable electronic signature within the meaning of WAC 173-303-180(11).
(ii) Any requirement in this section to give, provide, send, forward, or return to another person a copy of the manifest is satisfied when an electronic manifest is transmitted to the other person by submission to the e-Manifest system.
(iii) Any requirement in this section for a manifest to accompany a dangerous waste shipment is satisfied when a copy of an electronic manifest is accessible during transportation and forwarded to the person or persons who are scheduled to receive delivery of the waste shipment, except that to the extent that the hazardous materials regulation on shipping papers for carriage by public highway requires transporters of hazardous materials to carry a paper document to comply with 40 C.F.R. Part 177.817, a dangerous waste transporter must carry one printed copy of the electronic manifest on the transport vehicle. In addition, the one printed copy of the electronic manifest must provide the information required in WAC 173-303-180(6) for state-only dangerous waste that designates only by the criteria under WAC 173-303-100.
(iv) Any requirement in this section for a transporter to keep or retain a copy of each manifest is satisfied by retention of a signed electronic manifest in the transporter's account on the national e-Manifest system, provided that such copies are readily available for viewing and production upon request.
(v) A transporter may not be held liable for the inability to produce an electronic manifest for inspection under this section if the transporter can demonstrate that the inability to produce the electronic manifest is due exclusively to a technical difficulty with the EPA's electronic manifest system for which the transporter bears no responsibility.
(b) A transporter may participate in the electronic manifest system either by accessing the electronic manifest system from the transporter's own electronic equipment, or by accessing the electronic manifest system from the equipment provided by a participating generator, by another transporter, or by a designated facility.
(c) Special procedures when electronic manifest is not available. If after a manifest has been originated electronically and signed electronically by the initial transporter, and the electronic manifest system should become unavailable for any reason, then:
(i) The transporter in possession of the dangerous waste when the electronic manifest becomes unavailable shall reproduce sufficient copies of the printed manifest that is carried on the transport vehicle pursuant to (a)(iii) of this subsection, or obtain and complete another paper manifest for this purpose. The transporter shall reproduce sufficient copies to provide the transporter and all subsequent waste handlers with a copy for their files, plus two additional copies that will be delivered to the designated facility with the dangerous waste.
(ii) On each printed copy, the transporter shall include a notation in the special handling and additional description space (Item 14) that the paper manifest is a replacement manifest for the manifest originated in the electronic manifest system, shall include (if not preprinted on the replacement manifest) the manifest tracking number of the electronic manifest that is replaced by the paper manifest, and shall also include a brief explanation why the electronic manifest was not available for completing the tracking of the shipment electronically.
(iii) A transporter signing a replacement manifest to acknowledge receipt of the dangerous waste must ensure that each paper copy is individually signed and that a legible handwritten ink signature appears on each copy.
(iv) From the point at which the electronic manifest is no longer available for tracking the waste shipment, the paper replacement manifest copies shall be carried, signed, retained as records, and given to a subsequent transporter or to the designated facility, following the instructions, procedures, and requirements that apply to the use of all other paper manifests.
(d) Special procedures for electronic signature methods undergoing tests. If a transporter using an electronic manifest signs this manifest electronically using an electronic signature method which is undergoing pilot or demonstration tests aimed at demonstrating the practicality or legal dependability of this signature method, then the transporter shall sign the electronic manifest electronically and also sign with an ink signature the transporter acknowledgment of receipt of materials on the printed copy of the manifest that is carried on the vehicle in accordance with (a)(iii) of this subsection. This printed copy bearing the generator's and transporter's ink signatures shall also be presented by the transporter to the designated facility to sign in ink to indicate the receipt of the waste materials or to indicate discrepancies. After the owner/operator of the designated facility has signed this printed manifest copy with its ink signature, the printed manifest copy shall be delivered to the designated facility with the waste materials.
(e) Imposition of user fee. A transporter who is a user of the electronic manifest may be assessed a user fee by EPA for the origination or processing of each electronic manifest. EPA shall maintain and update from time-to-time the current schedule of electronic manifest user fees, which shall be determined based on current and projected system costs and level of use of the electronic manifest system. The current schedule of electronic manifest user fees will be published as an appendix to 40 C.F.R. Part 262, by EPA.
(f) Post-receipt manifest data corrections. After facilities have certified to the receipt of dangerous waste by signing Item 20 of the manifest, any post-receipt data corrections may be submitted at any time by any interested person (e.g., waste handler) named on the manifest. Transporters may participate electronically in the post-receipt data corrections process by following the process described in WAC 173-303-370 (10)(g), which applies to corrections made to either paper or electronic manifest records.

General requirements for dangerous waste management facilities.

(1) Applicability. The requirements of WAC 173-303-280 through 173-303-395 apply to all owners and operators of facilities which store, treat, or dispose of dangerous wastes and which must be permitted under the requirements of this chapter 173-303 WAC, unless otherwise specified in this chapter. Whenever a shipment of dangerous waste is initiated from a facility, the owner or operator of that facility must comply with the requirements for generators, WAC 173-303-170 through 173-303-230.
(2) Imminent hazard. Notwithstanding any provisions of this chapter, enforcement actions may be brought in the event that the management practices of a facility present an imminent and substantial hazard to the public health and the environment, regardless of the quantity or concentration of a dangerous waste.
(3) Identification numbers. Every facility owner or operator must apply for an EPA/state identification number from the department in accordance with WAC 173-303-060.
(4) The owner or operator must comply with the special land disposal restrictions for certain dangerous wastes in WAC 173-303-140.
(5) Salt dome formations, salt bed formations, underground mines and caves. The placement of any noncontainerized or bulk liquid dangerous waste in any salt dome formation, salt bed formation, underground mine or cave is prohibited.
(6) The requirements of WAC 173-303-290 through 173-303-360 and WAC 173-303-395 do not apply to cleanup-only facilities. Instead, owners/operators of cleanup-only facilities must comply with the following requirements.
(a) Obtain an EPA/state identification number in accordance with WAC 173-303-060(2).
(b) Obtain a detailed chemical and physical analysis of a representative sample of the dangerous remediation waste to be treated, stored or disposed at the site. At a minimum, this analysis must contain all information that must be known to treat, store or dispose of the dangerous remediation waste according to WAC 173-303-140 (2)(a), 173-303-280 through 173-303–395 and WAC 173-303-600 through 173-303-695 and must be kept accurate and up to date.
(c) Prevent people who are unaware of the danger from entering, and minimize the possibility for unauthorized people or livestock to enter onto the active portion of the remediation waste management site, unless the owner or operator can demonstrate to the director that:
(i) Physical contact with the dangerous remediation waste, structures or equipment within the active portion of the remediation waste management site will not injure people or livestock who may enter the active portion of the remediation waste management site; and
(ii) Disturbance of the dangerous remediation waste or equipment by people or livestock who enter onto the active portion of the remediation waste management site will not cause a violation of the requirements of WAC 173-303-280 through 173-303-395 or WAC 173-303-600 through 173-303-695.
(d) Inspect the remediation waste management site for malfunctions, deterioration, operator errors, and discharges that may lead to a release of dangerous constituents to the environment or a threat to human health. Inspections must be conducted often enough to identify problems in time to correct them before they harm human health or the environment. Problems must be remedied before they lead to a human health or environmental threat. Where a hazard is imminent or has already occurred, remedial action must be taken immediately.
(e) Provide personnel with classroom or on-the-job training on how to perform their duties in a way that ensures the remediation waste management site complies with the requirements of WAC 173-303-280 through 173-303–395 and WAC 173-303-600 through 173-303-695 and on how to effectively respond to emergencies.
(f) Take precautions to prevent accidental ignition or reaction of ignitable or reactive dangerous remediation waste and prevent threats to human health and the environment from ignitable, reactive and incompatible dangerous remediation waste.
(g) Develop and maintain a construction quality assurance program for all surface impoundments, waste piles and landfill units that are required to comply with WAC 173-303-650 (2)(j) and (k), 173-303-660 (2)(j) and (k) or 173-303-655 (2)(h), (i) and (j). The construction quality assurance must meet the requirements of WAC 173-303-335.
(h) Develop and maintain procedures to prevent accidents and a contingency and emergency plan to control accidents that occur. The procedures must address proper design, construction, maintenance and operation of remediation waste management units at the site. The goal of the plan must be to minimize the possibility of, and the hazards from, a fire, explosion or any other unplanned sudden or nonsudden release of dangerous remediation waste or dangerous constituents to the air, soil or surface water that could threaten human health or the environment. The plan must explain specifically how to treat, store or dispose of the remediation waste in question and must be implemented immediately whenever a fire, explosion or release of dangerous remediation waste or dangerous constituents occurs and could threaten human health or the environment.
(i) Designate at least one employee, either on the remediation waste management site premises or on call (that is, available to respond to an emergency by reaching the remediation waste management site quickly), to coordinate all emergency response measures. The emergency coordinator must be thoroughly familiar with all aspects of the remediation waste management site contingency plan, all operations and activities at the site, the location and characteristics of dangerous remediation waste handled, the location of all records within the site, and the site layout. The emergency coordinator must have authority to commit the resources needed to carry out the contingency plan.
(j) Develop, maintain and implement a plan to meet the requirements of this subsection.
(k) Maintain records documenting compliance with this subsection.

Siting criteria.

(1) Purpose. This section establishes siting criteria which serve as an initial screen in the consideration of sites for dangerous waste management facilities. The purpose of the siting criteria is to immediately disqualify proposed dangerous waste facility sites in locations considered unsuitable or inappropriate for the management of dangerous wastes. Under RCW 70.105.200 (1)(d), siting criteria cannot prevent existing dangerous waste management facilities from operating at or below their present level of activity.
A proposed site which is not disqualified under these criteria will be further studied to determine if it qualifies under site specific rules. Compliance with the siting criteria does not imply that a given project at a given location poses an acceptable level of risk, nor does it commit the department to the issuance of a dangerous waste permit. Projects that demonstrate compliance with the siting criteria will be subjected to comprehensive environmental and technical review pursuant to applicable laws and regulations before the department makes a final decision on a dangerous waste permit.
The department may deny a permit or require protective measures such as engineering enhancements or increased setback distances from resources in order to ensure protection of human health and the environment.
(2) Applicability.
(a) Except as otherwise specifically provided, this section applies to:
(i) Owners/operators of proposed facilities; and
(ii) Owners or operators of existing land-based facilities at which an expansion of the land based unit is proposed;
(iii) Owners or operators of existing incinerators at which an expansion is proposed; and
(iv) Owners or operators proposing a significant expansion of other existing dangerous waste management facilities not subject to (a)(i), (ii) and (iii) of this subsection, unless the owner/operator can demonstrate to the satisfaction of the department that the proposed expansion will provide a net increase in protection to human health and the environment beyond that which is currently provided at the facility. However, demonstrations under this subsection (iv) must not result in treatment or storage facilities expanding into land-based or incineration facilities if siting criteria cannot be satisfied.
(b) This section does not apply to:
(i) Owners/operators of facilities or portions of facilities who are applying for research, development and demonstration permits, pursuant to section 3005(g) of the Resource Conservation and Recovery Act, codified in 40 C.F.R. Part 270.65 or WAC 173-303-809;
(ii) Owners/operators of facilities operating under an emergency permit pursuant to WAC 173-303-804;
(iii) Persons at facilities conducting on-site cleanup of sites under the Comprehensive Environmental Response Compensation and Liability Act, Sections 3004(u), 3004(v), and 3008(h) of the Resource Conservation and Recovery Act, chapter 70.105 RCW, or chapter 70.105D RCW, provided the cleanup activities are being conducted under a consent decree, agreed order, or enforcement order, or is being conducted by the department or United States Environmental Protection Agency;
(iv) Persons managing solid wastes who become subject to dangerous waste regulations through amendments to this chapter after the effective date of this section. This provision applies only to those activities operated in accordance with local, state, and federal requirements and which were being conducted prior to becoming subject to dangerous waste regulations, chapter 173-303 WAC or expansions, if it can be demonstrated to the satisfaction of the department that the proposed expansion of such activities will provide a net increase in protection to human health and the environment beyond that which is currently provided at the facility; or
(v) Owners/operators of facilities who seek to obtain a dangerous waste permit for waste storage and satisfy all of the following:
(A) The facility recycles dangerous waste in a process that is exempt from dangerous waste permitting.
(B) Waste storage is used strictly to support the exempt recycling.
(C) Waste storage is in tanks, containers, or a containment building.
(D) Waste storage is indoors.
(3) Definitions. Any terms used in this section that are not defined below have the meanings provided in WAC 173-303-040. For the purposes of this section, the following terms have the described meanings:

These facilities use the land as an integral part of their waste management method and include, but are not limited to, landfills, surface impoundments, waste piles, and land treatment facilities. For the purposes of this section, this would not include waste piles in which the dangerous wastes are stored inside or under a structure that provides protection from precipitation and when runoff, leachate, or other types of waste dispersal are not generated under any conditions.
(i) "Nonland based facility" means a facility which does not use the land as an integral part of its waste management method and is not subject to the requirements of WAC 173-303-806 (4)(a)(xxi). These facilities include, but are not limited to, tanks, containers, and incinerators.
(j) "Perennial surface water body" means a surface water body which is normally continuous with natural flows throughout the year or an annually recurring body of water including lakes, rivers, ponds, streams, reservoirs, inland waters, and saltwaters. This does not include roadside ditches or storm drains. However, this definition does apply to irrigation or domestic water supply channels existing, or planned and approved by a governmental agency, at the time an owner/operator submits a notice of intent.
(k) "Preempted facility" means any facility that includes as a significant part of its activities any of the following operations: (i) Landfill; (ii) incineration; (iii) land treatment; (iv) surface impoundment to be closed as a landfill; or (v) waste pile to be closed as a landfill.
(l) "Prime farmland" means the land which has the best combination of physical and chemical characteristics for producing food, feed, forage, fiber or oilseed crops, and is also available for these uses. It has the soil quality, growing season, and moisture supply needed to economically produce sustained high yields of crops when treated and managed, including water management, according to acceptable farming methods. In general, prime farmland has an adequate and dependable water supply from precipitation or irrigation, a favorable temperature and growing season, acceptable acidity or alkalinity, acceptable salt and sodium content, and few or no rocks. It is permeable to water and air. Prime farmland is not excessively erodible or saturated with water for a long period of time, and it either does not flood frequently or is protected from flooding. Prime farmland will be determined by those general and specific criteria as defined in the National Soils Handbook, Soil Conservation Service, United States Department of Agriculture, Washington, D.C. and 7 C.F.R. 2.62. Areas of prime farmland are identified in the most recent county soil survey maps prepared by the National Cooperative Soil Survey.

General waste analysis.

(1) Purpose. This section requires the facility owner or operator to confirm his knowledge about a dangerous waste before he stores, treats, or disposes of it. The purpose for the analysis is to insure that a dangerous waste is managed properly.
(2) The owner or operator must obtain a detailed chemical, physical, and/or biological analysis of a dangerous waste, or nondangerous wastes if applicable under WAC 173-303-610 (4)(d), before they store, treat, or dispose of it. This analysis must contain the information necessary to manage the waste in accordance with the requirements of this chapter. The analysis must include or consist of existing published or documented data on the dangerous waste, or on waste generated from similar processes, or data obtained by testing, or a combination of these.
(a) When an owner or operator relies on knowledge from the generator for waste designation or for this detailed analysis (commonly known as a waste profile) instead of analytical testing of a sample, that information must be documented and must meet the definition of "knowledge" as defined in WAC 173-303-040. To confirm the sufficiency and reliability of the "knowledge" used for the waste profile, the facility must do one or more of the following:
(i) Be familiar with the generator's processes by conducting site visits, and reviewing sampling data and other information provided by the generator to ensure they are adequate for safe management of the waste;
(ii) Ensure waste analysis contained in documented studies on the generator's waste is based on representative and appropriate sampling and test methods;
(iii) Compare the generator's waste generating process to documented studies of similar waste generating processes to ensure the waste profile is accurate and current;
(iv) Obtain other information as predetermined by
