(6) Land application – Permit requirements – Operation. The owner or operator of a land application site must:
(a) Operate the site in compliance with the performance standards of WAC 173-350-040 and this section. In addition the owner or operator must develop, keep, and follow a plan of operation approved as part of the permitting process. The plan of operation must be available for inspection at the request of the jurisdictional health department. If necessary, the plan may be modified with the approval, or at the direction of the jurisdictional health department. Each plan of operation must include the following:

(ii) A description of the processes by which the solid waste is generated and treated;
(iii) A description of the characteristics of the waste that provide agronomic, soil-amending, or reclamation capability;
(iv) A waste monitoring plan that provides representative characterization of the waste over time;
(v) A description of how the owner or operator will ensure that land application occurs at a predictable application rate determined as follows:
(A) For agricultural applications, solid waste must be applied to the land at a rate that does not exceed the agronomic rate. The agronomic rate should be based on Washington State University cooperative extension service fertilizer guidelines or other appropriate resources accepted by the jurisdictional health department;
(B) For the purposes of land reclamation or other soil amending activities, the application rate may be designed, for example, to achieve a soil organic matter content or other soil physical characteristics to promote long-term soil productivity, with consideration of the carbon-to-nitrogen ratio to control nutrient leaching; and
(C) For liquid wastes, the application rate must also be based on soil permeability and infiltration rate.
(vi) A description of how the owner or operator will determine the application rate that accounts for the characteristics of the waste to be applied, characteristics of receiving site soils, irrigation practices, climate, and the crop to be grown;
(vii) A description of the process, system, and equipment that will be used to apply the waste that explains:
(A) How the equipment and system will be calibrated to deliver waste at the appropriate rate;
(B) Whether the waste will be allowed to remain on the surface of the land, tilled into the soil, or injected into the soil at the time of application;
(C) When the waste will be applied to the land relative to crop and livestock management practices; and
(D) Any restrictions on application related to climatic factors including typical precipitation, twenty-five-year storm events, temperature, wind, frozen soils, saturated soils, or seasonal high groundwater.
(viii) A description of how the waste will be managed at all points during storage and application to control attraction to vectors and to mitigate nuisance odor impacts (unless exempted under chapter 70.94 RCW, Washington Clean Air Act), including a description of how owners or operators will respond to complaints;
(ix) If the seasonal high groundwater is three feet or less below the surface, a management plan describing how groundwater will be protected;

(A) Contamination of groundwater, surface water, air, and land during storage is prevented;
(B) The potential for combustion within the pile is minimized;
(C) The duration of storage of the entire pile is limited to one year and limited to the amount that will be applied to the site during a one-year period according to the plan of operation, or less if the jurisdictional health department believes it is necessary to prevent the contamination of groundwater, surface water, air, or land. Subsequent accumulation under the same conditions is allowed at the same location after the entire pile has been used; and
(D) For piles that will not meet conditions of (A) through (C) of this subsection, a demonstration that the owner or operator will meet the requirement of WAC 173-350-320.
(xi) For waste stored in piles somewhere other than the land application site, a description of how the owner or operator will meet the requirements of WAC 173-350-320;
(xii) For storage of liquid waste or semisolid waste in surface impoundments or tanks, a description of how the owner or operator will meet the requirements of WAC 173-350-330;
(xiii) A description of how the owner or operator will maintain operating records of the location where waste is applied, amount and type of waste applied, the crop planted, and other nutrient inputs, including the form or computer printout used to record this information. Facility annual reports must be maintained in the operating record. Significant deviations from the plan of operation must be noted in the operating record. Records must be kept for a minimum of five years and be available upon request by the jurisdictional health department; and
(xiv) Other details to demonstrate that the facility will be operated in accordance with this subsection and as required by the jurisdictional health department.
