(a) Facilities other than those in the sand and gravel, shipyard, or RCRA categories that operate within several fee categories or subcategories, shall be charged from that category or subcategory with the highest fee.

(b) The total annual permit fee for a water treatment plant that primarily serves residential customers may not exceed three dollars per residential equivalent. The number of residential equivalents is determined by dividing the facility's annual gross revenue in the previous calendar year by the annual user charge for a single family residence that uses nine hundred cubic feet of water per month.

(c) Fruit packer, sand and gravel, and winery permit holders are required to submit information to the department certifying annual production (calendar year) or unit processes. The permit holder shall submit the information to the department by the required due date. Failure to provide this information results in a fee determination based on the highest subcategory the facility has received permit coverage in.

(i) Information submitted shall bear a certification of correctness and be signed:

(A) In the case of a corporation, by an authorized corporate officer;

(B) In the case of a limited partnership, by an authorized partner;

(D) In the case of a sole proprietorship, by the proprietor.

(ii) The department may verify information submitted and, if it determines that false or inaccurate statements have been made, it may, in addition to taking other actions provided by law, revise both current and previously granted fee determinations.

(d) Fees for fruit packers 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.

(e) Where no clear industrial facility category exists for placement of a permit holder, the department may elect to place the permit holder in a category with dischargers or permit holders that contain or use similar properties or processes and/or a category which contains similar permitting complexities to the department.

(f) Hazardous waste cleanup sites and EPA authorized RCRA corrective action sites with whom the department has begun cost recovery through chapter 70A.305 RCW shall not pay a permit fee under chapter 173-224 WAC until such time as the cost recovery under chapter 70A.305 RCW ceases.

(g) Any permit holder, with the exception of nonoperating sand and gravel operations or a permitted portable facility, who has not been in continuous operation within a consecutive eighteen-month period or who commits to not being in operation for a consecutive eighteen-month period or longer can have their permit fee reduced to twenty-five percent of the fee that they would be otherwise assessed. This nonoperating mode may be verified by the appropriate ecology staff. Once operations resume, the permit fee returns to the full amount.

Facilities who commit to the minimum eighteen-month nonoperating mode but go back into operation during the same eighteen-month period are assessed permit fees as if they were active during the entire period.

(h) Facilities with subcategories based on gallons per day (gpd) shall have their annual permit fee determined by using the maximum daily flow or maximum monthly average permitted flow in gallons per day as specified in the waste discharge permit, whichever is greater.

(i) RCRA corrective action sites requiring a waste discharge permit are assessed a separate 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.

(3) MUNICIPAL/DOMESTIC FACILITIES

(a) The annual permit fee for a permit held by a municipality for a domestic wastewater facility issued under RCW 90.48.162 or 90.48.260 is determined as follows:

Residential Equivalents (RE)	FY 2022 Annual Permit Fee	FY 2023 Annual Permit Fee & Beyond
< 250,000	$2.16	$2.16
˃ 250,000	2.16	2.16

(b) The annual permit fee under RCW 90.48.162 or 90.48.260 that is held by a municipality which:

(i) Holds more than one permit for domestic wastewater facilities; and

(ii) Treats each domestic wastewater facility as a separate accounting entity, is determined as in (a) of this subsection.

A separate accounting entity is one that maintains separate funds or accounts for each domestic wastewater facility. Revenues are received from the users to pay for the costs of operating that facility.

(i) Holds more than one permit for domestic wastewater facilities issued under RCW 90.48.162 or 90.48.260; and

(ii) Does not treat each domestic wastewater facility as a separate accounting entity, as described in (b) of this subsection, is determined as in (a) of this subsection.

(d) The permit fee for a privately owned and public-owned domestic wastewater facility that primarily serves residential customers is determined as in (a) of this subsection. Residential customers are those whose lot, parcel or real estate, or building is primarily used for domestic dwelling purposes.

(e) The annual permit fee for privately owned or public-owned domestic wastewater facilities must be determined by using the maximum daily flow or maximum monthly average permitted flow in million gallons per day, whichever is greater, as specified in the waste discharge permit. Permit fees for privately owned or public-owned domestic wastewater facilities that do not serve primarily residential customers and for state-owned domestic wastewater facilities are the following:

Permitted Flows	FY2022 Annual Permit Fee	FY 2023 Annual Permit Fee & Beyond
.1 MGD and Greater	$15,075.00	$15,075.00
.05 MGD to < .1 MGD	6,032.00	6,032.00
.0008 MGD to < .05 MGD	3,016.00	3,016.00
< .0008 MGD	910.00	910.00

(f) The number of residential equivalents is calculated in the following manner:

(i) If the facility serves only single-family residences, the number of residential equivalents is the number of single-family residences that it served on January 1 of the previous calendar year.

(ii) If the facility serves both single-family residences and other classes of customers, the number of residential equivalents is calculated in the following manner:

(A) Calculation of the number of residential equivalents that the facility serves in its own service area. Subtract from the previous calendar year's gross revenue:

(I) Any amounts received from other municipalities for sewage interception, treatment, collection, or disposal; and

(II) Any user charges received from customers for whom the permit holder pays amounts to other municipalities for sewage treatment or disposal services. Divide the resulting figure by the annual user charge for a single-family residence.

(B) Calculation of the number of residential equivalents that the facility serves in other municipalities which pay amounts to the facility for sewage interception, treatment, collection, or disposal:

(I) Divide any amounts received from other municipalities during the previous calendar year by the annual user charge for a single-family residence. In this case "annual user charge for a single-family residence" means the annual user charge that the facility charges other municipalities for sewage interception, treatment, collection, or disposal services for a single-family residence. If the facility charges different municipalities different single-family residential user fees, then the charge used in these calculations must be that which applies to the largest number of single-family residential customers. Alternatively, if the facility charges different municipalities different single-family residential user fees, the permit holder may divide the amount received from each municipality by the annual user charge that it charges that municipality for a single-family residence and sum the resulting figures.

(II) If the facility does not charge the other municipality on the basis of a fee per single-family residence, the number of residential equivalents in the other municipality is calculated by dividing its previous calendar year's gross revenue by its annual user fee for a single-family residence. If the other municipality does not maintain data on its gross revenue, user fees, and/or the number of single-family residences that it serves, the number of residential equivalents is calculated as in (f)(iv) of this subsection.

(III) If the other municipality serves only single-family residences, the number of residential equivalents may be calculated as in (f)(i) of this subsection.

The sum of the resulting figures is the number of residential equivalents that the facility serves in other municipalities.

(C) The number of residential equivalents is the sum of the number of residential equivalents calculated in (f)(ii)(A) and (B) of this subsection.

(iii) The annual user fee for a single-family residence is calculated by either of the following methods, at the choice of the permit holder:

(A) The annual user fee for a single-family residence using nine hundred cubic feet of water per month. If users are billed monthly, this is calculated by multiplying by twelve the monthly user fee for a single-family residence using nine hundred cubic feet of water per month. If users are billed bimonthly, the annual user fee is calculated by multiplying by six the bimonthly user fee for a single-family residence using one thousand eight hundred cubic feet of water per two-month period. If the user fee for a single-family residence varies, depending on age, income, location, etc., then the fee used in these calculations must be that which applies to the largest number of single-family residential customers.

(B) The average annual user fee for a single-family residence. This average is calculated by dividing the previous calendar year's gross revenue from provision of sewer services to single-family residences by the number of single-family residences served on January 1 of the previous calendar year. If the user fee for a single-family residence varies, depending on age, income, location, etc., then the gross revenue and number of single-family residences used in making this calculation must be those for all the single-family residential customers.

In either case, (f)(iii)(A) or (B) of this subsection, the permit holder must provide the department with a copy of its complete sewer rate schedule for all classes of customers.

(iv) If a permit holder does not maintain data on its gross revenue, user fees, and/or the number of single-family residences that it serves, and therefore cannot use the methods described in (f)(i) or (ii) of this subsection to calculate the number of residential equivalents that it serves, then the number of residential equivalents that it serves is calculated by dividing the average daily influent flow to its facility for the previous calendar year by two hundred fifty gallons. This average is calculated by summing all the daily flow measurements taken during the previous calendar year and then dividing the resulting sum by the number of days on which flow was measured. Data for this calculation must be taken from the permit holder's discharge monitoring reports. Permit holders using this means of calculating the number of their residential equivalents must submit with their application a complete set of copies of their discharge monitoring reports for the previous calendar year.

(g) Fee calculation procedures for holders of permits for domestic wastewater facilities.

(i) Municipalities holding permits for domestic wastewater facilities issued under RCW 90.48.162 and 90.48.260, and holders of permits for privately owned domestic wastewater facilities that primarily serve residential customers must complete a form certifying the number of residential equivalents served by their domestic wastewater system. The form must be completed and returned to the department within thirty days after it is mailed to the permit holder by the department. Failure to return the form could result in permit termination.

(ii) The form shall bear a certification of correctness and be signed:

(A) In the case of a corporation, by an authorized corporate officer;

(B) In the case of a limited partnership, by an authorized partner;

(D) In the case of a sole proprietorship, by the proprietor; or

(E) In the case of a municipal or other public facility, by either a ranking elected official or a principal executive officer.

(iii) The department may verify the information contained in the form and, if it determines that the permit holder has made false statements, may, in addition to taking other actions provided by law, revise both current and previously granted fee determinations.

(h) The annual permit fee for a domestic wastewater facility with a Puget Sound nutrient general permit will be calculated at the rate of $0.31 per residential equivalent per year. The number of residential equivalents will be calculated as described in (g) of this subsection. The permit fee in this subsection will not be assessed for municipal domestic wastewater treatment facilities unless the legislature amends RCW 90.48.465(2) to authorize this fee.

(5) MUNICIPAL SEPARATE STORM SEWER SYSTEM PERMITS

(a) Except as provided for in (d) of this subsection, the municipal stormwater permit annual fee for the entities listed below is:

Name of Entity	FY2022 Annual Permit Fee	FY2023 Annual Permit Fee & Beyond
King County	$68,695.00	$68,695.00
Snohomish County	68,695.00	68,695.00

Clark County	68,695.00	68,695.00

(b) Municipal stormwater general permit fees for cities and counties, except as otherwise provided for in (a), (c), and (d) of this subsection, are determined in the following manner: For fiscal years 2022 and 2023 and beyond, ecology will charge $1.99 per housing unit inside the geographic area covered by the permit for those cities and counties whose median household income exceeds the state average. Cities and counties whose median household income is less than the state average will have their fee per housing unit reduced to $.98 per housing unit inside the geographic area covered by the permit. Fees will not exceed $68,695.00 for fiscal years 2022 and 2023 and beyond. The minimum annual fee will not be lower than $2,856.00 for fiscal years 2022 and 2023 and beyond unless the permitted city or county has a median household income less than the state average. In this case, the city or county will pay a fee totaling $.98 per housing unit for fiscal years 2022 and 2023 and beyond.

(c) Other entities required to have permit coverage under a municipal stormwater general permit will pay an annual fee based on the entities' previous year's annual operating budget as follows:

Annual Operating Budget	FY2022 Annual Permit Fee	FY2023 Annual PermitFee & Beyond
Less than $100,000	$199.00	$199.00
$100,000 - < $1,000,000	805.00	805.00
$1,000,000 - < $5,000,000	2,009.00	2,009.00

$10,000,000 and greater	5,024.00	5,024.00

For the purposes of determining the annual permit fee category, the annual operating budget shall be the entities' annual operating budget for the entities' previous fiscal year and shall be determined as follows:

(i) For diking, drainage, irrigation, and flood control districts, the district's annual operating budget.

(ii) For ports, the annual operating budget for the port district.

(iii) For colleges, schools, and universities, the portion of the operating budget related to plant or facilities operation and maintenance for the site or sites subject to the permit.

(iv) For state agencies, the annual operating budget for the site or sites subject to the permit.

(v) For other entities not listed, ecology will consider annual revenue, and the noncapital operating budget for the site subject to the permit.

(d) Municipal stormwater permits written specifically for a single entity, such as a single city, county, or agency, issued after the effective date of this rule will have its annual fee determined in the following manner:

(i) For cities and counties listed in (a) of this subsection, the fee shall be five times the amount identified.

(ii) For cities and counties whose median household income exceeds the state average, the fee shall be the higher of either five times the otherwise applicable general permit fee or $30,000. For municipalities whose median household income is less than the state average, the fee shall be the higher of 2.5 times the otherwise applicable general permit fee or $15,000.

(iii) For entities that would otherwise be covered under a municipal stormwater general permit as determined in (c) of this subsection, the fiscal years 2022 and 2023 annual fee and beyond for a permit written for a specific entity is $14,290.00.

(e) Ecology will assess a single permit fee for entities which apply only as copermittees or coapplicants. The permit fee shall be equal to the highest single permit fee which would have been assessed if the copermittees had applied separately.
