Permit fee schedule.

(1) Application fee. In addition to an annual fee, first time individual permit applicants must pay a nonrefundable application fee of 25 percent of the annual permit fee, or $275, whichever is greater. An application fee is assessed for RCRA corrective action sites regardless of whether a new permit is issued or an existing permit for other than the discharge resulting from the RCRA corrective action, is modified.
(2) Minimum fee. The minimum water quality annual permit fee is $165.00, unless specified elsewhere in this section. The department may elect, at its discretion, to assess this minimum fee when no better permit fee category applies, or when a prorated annual permit fee falls below the minimum fee amount.
(3) INDUSTRIAL FACILITY ANNUAL PERMIT FEE SCHEDULE

(a) Facilities are assessed a fee or fees that best aligns with the category and subcategory relevant to their water quality discharge. Except for CAFO, RCRA, sand and gravel, shipyard, and vessel deconstruction that operate within multiple fee subcategories, if the facility fits within several categories or subcategories, then the permit holder is assessed the highest fee.
(b) CAFO, fruit packing, sand and gravel, vessel deconstruction and winery permit holders must submit information to the department certifying annual unit amounts or production during the previous calendar year. The permit holder must submit the information to the department by the required due date. Failure to provide this information will result in a fee determination based on the highest subcategory for which the facility has received permit coverage.
(c) Information submitted on the required form must include a signature certifying the information is correct:
(i) For a corporation, by an authorized corporate officer;
(ii) For a limited partnership, by an authorized partner;
(iii) For a general partnership, by an authorized general partner; or
(iv) For a sole proprietorship, by the proprietor.
(d) The department may verify information submitted and, if it determines that false statements have been made, it will, revise both current and previously granted fee determinations as appropriate, in addition to taking other actions provided by law.
(e) Fees for fruit packing facilities discharging only noncontact cooling water without additives shall pay the lesser of the applicable fee in the fruit packing or noncontact cooling water without additives categories. Any fruit packing facility with an inactive permit status shall be assessed the lowest bin per year fee or lowest noncontact cooling water fee, as determined by the department.
(f) Where no clear industrial facility category exists for placement of a permit holder, the department will place the permit holder in a category with dischargers or permit holders that contain or use similar properties or processes or a category that contains similar permitting complexities. If no such category exists, the department will assess the minimum permit fee as specified in this section, until an appropriate permit fee category can be added to the rule.
(g) Hazardous waste cleanup sites and EPA authorized RCRA corrective action sites where the department has begun cost recovery through chapter 70A.305 RCW shall not pay an annual permit fee under this chapter until such time as the cost recovery under chapter 70A.305 RCW ceases.
(h) Any permit holder (with the exception of those fee categories that already take nonoperation or reduced discharge into consideration), who has not been discharging within a consecutive 18-month period to include the assessed fiscal year or who commits to not discharging for a consecutive 18-month period or longer may request a rate reduction of their annual permit fee by submitting the required request form. The full annual rate may be reduced to no less than 35 percent of the annual permit fee that would otherwise be assessed, as determined by the department. The department may also deny a request for the reduced rate, if the request does not allow the department to fully recover program costs per RCW 90.48.465(1), and/or the permit includes other conditions besides discharge. The discharge and permit conditions status may be verified by the appropriate department staff. After the reduced rate fee status for the 18-month period ends, the permit fee returns to the full amount. The permit holder must submit another request form to extend the reduced rate fee for another 18 months.
If a permit holder resumes discharging or the site circumstances that resulted in a reduced fee change during the 18-month period, the full permit fee is due for that fiscal year. The reduced rate fee paid, will be applied to the full fee due.
(i) Facilities with subcategories based on gallons per day (gpd) shall have their annual permit fee determined by using the design maximum, maximum daily flow, or maximum monthly average permitted flow in gallons per day as specified in the waste discharge permit, whichever is greater.
(j) RCRA corrective action sites requiring a waste discharge permit are assessed a separate annual permit fee regardless of whether the discharge is authorized by a separate permit or by a modification to an existing permit for a discharge other than that resulting from the corrective action.
(4) MUNICIPAL AND DOMESTIC WASTEWATER FACILITIES ANNUAL PERMIT FEE SCHEDULE
The following municipal and domestic wastewater facilities must pay an annual permit fee as follows:
(a) The annual permit fee for a permit held by a municipality or federally recognized tribe for a domestic wastewater facility issued under RCW 90.48.162 or 90.48.260 is determined as follows:
Residential Equivalents (RE)
FY 2026 Permit Fee
FY 2027 Permit Fee
The annual fee is calculated by multiplying the number of REs by the FY per RE rate, for permit holders with 100 or more REs
 
 
For permit holders with less than 100 REs, a flat fee will be assessed
 
 
Less than 100 REs (Minimum Muni WW Fee)
$275 flat fee

Less than 250,000 REs

$3.57 per RE
(b) The annual permit fee for privately owned or public-owned domestic wastewater facilities permitted under RCW 90.48.162 or 90.48.260 (that do not primarily serve residential customers), privately owned or public-owned reclaimed water facilities permitted exclusively under RCW 90.46.220, and for state-owned domestic wastewater and reclaimed water facilities is determined by using the design flow, or maximum daily flow or maximum monthly average permitted flow in million gallons per day, whichever is greater, as specified in the waste discharge or reclaimed water permit. The annual flow-based fees for wastewater and reclaimed water facilities are as follows:
Tiered Flow-Based Fee

(c) Instructions for calculating residential equivalents and reporting flow under (a) of this subsection are provided on annual forms sent by the department to permit holders each year. Permit holders are required to complete and return the forms and any required back-up documentation to the department by the specified due date. Failure to return the annual form and any required back-up documentation will result in a permit fee as determined by the department.
(i) The annual forms must include a signature certifying the provided information is correct:
(A) For a corporation, by an authorized corporate officer;
(B) For a limited partnership, by an authorized partner;
(C) For a general partnership, by an authorized partner;
(D) For a sole proprietorship, by the proprietor; or
(E) For a municipal or other public facility, by either a ranking elected official or a principal executive officer.
(ii) The department may verify the information contained in the submitted documentation and, if it determines that the permit holder has made false statements, will, revise both current and previously granted fee determinations as appropriate, in addition to taking other actions provided by law.
(d) The annual permit fee for all Puget Sound domestic wastewater facilities will be calculated at the rate of $0.31 per residential equivalent per year or the $275 minimum wastewater fee described in this section, as determined by the department. The number of residential equivalents will be calculated based on information provided on the forms required in this section.
