B. C. The disbursement of grants for the design and installation of nutrient removal technology at those publicly owned treatment works included in subsection E F and eligible nonsignificant dischargers shall be made monthly based on a requisition submitted by the grant recipient in the form requested by the Department. Each requisition shall include written certification that the applicable local share of the cost of nutrient removal technology for that portion of the project covered by such requisition has been incurred or expended. Except as may otherwise be approved by the Department, disbursements shall not exceed 95 percent of the total grant amount until satisfactory completion of the project. The distribution of the grants shall be effected by one of the following methods:

1. In payments to be paid by the State Treasurer out of funds appropriated to the Water Quality Improvement Fund pursuant to § 10.1-2131;

2. Over a specified time through a contractual agreement entered into by the Treasury Board and approved by the Governor, on behalf of the Commonwealth, and the locality or public service authority undertaking the design and installation of nutrient removal technology, such payments to be paid by the State Treasurer out of funds appropriated to the Treasury Board; or

3. In payments to be paid by the State Treasurer upon request of the Director of Environmental Quality out of proceeds from bonds issued by the Virginia Public Building Authority, in consultation with the Department of Environmental Quality, pursuant to §§ 2.2-2261, 2.2-2263, and 2.2-2264, including the Commonwealth's share of the interest costs expended by the locality or regional authority for financing such project during the period from 50% 50 percent completion of construction to final completion of construction.

C. D. The General Assembly shall have has the sole authority to determine whether disbursement will shall be made pursuant to subdivision B C 1, B 2, or B 3, or a combination thereof;, provided that a disbursement shall only be made pursuant to subdivision B C 3 only upon a certification by the Department of Environmental Quality that project grant reimbursements for the fiscal year will exceed the available funds in the Water Quality Improvement Fund.

D. E. Exclusive of any deposits made pursuant to § 10.1-2128, the grants awarded pursuant to this section shall include such appropriations as provided for in Chapter 951 of the Acts of Assembly of 2005; and Chapter 10 of the Acts of Assembly of 2006, Special Session I from time to time in the appropriation act or any amendments thereto.

§ 62.1-44.19:14. Watershed general permit for nutrients.

A. By January 1, 2006, or as soon thereafter as possible, the The Board shall issue a Watershed General Virginia Pollutant Discharge Elimination System Permit, hereafter referred to as the general permit, authorizing point source discharges of total nitrogen and total phosphorus to the waters of the Chesapeake Bay and its tributaries. Except as otherwise provided in this article, the general permit shall control in lieu of technology-based, water quality-based, and best professional judgment, interim or final effluent limitations for total nitrogen and total phosphorus in individual Virginia Pollutant Discharge Elimination System permits for facilities covered by the general permit where the effluent limitations for total nitrogen and total phosphorus in the individual permits are based upon standards, criteria, waste load allocations, policy, or guidance established to restore or protect the water quality and beneficial uses of the Chesapeake Bay or its tidal tributaries.

B. This section shall not be construed to limit or otherwise affect the Board's authority to establish and enforce more stringent water quality-based effluent limitations for total nitrogen or total phosphorus in individual permits where those limitations are necessary to protect local water quality. The exchange or acquisition of credits pursuant to this article shall not affect any requirement to comply with such local water quality-based limitations.

C. The general permit shall contain the following:

1. Waste load allocations for total nitrogen and total phosphorus for each permitted facility expressed as annual mass loads, including reduced waste load allocations where applicable under the ENRC Program. The allocations for each permitted facility shall reflect the applicable individual water quality-based total nitrogen and total phosphorus waste load allocations. An owner or operator of two or more facilities located in the same tributary may apply for and receive an aggregated waste load allocation for total nitrogen and an aggregated waste load allocation for total phosphorus for multiple facilities reflecting the total of the water quality-based total nitrogen and total phosphorus waste load allocations established for such facilities individually;

2. A schedule requiring compliance with the combined waste load allocations for each tributary as soon as possible taking into account (i) opportunities to minimize costs to the public or facility owners by phasing in the implementation of multiple projects; (ii) the availability of required services and skilled labor; (iii) the availability of funding from the Virginia Water Quality Improvement Fund as established in § 10.1-2128, the Virginia Water Facilities Revolving Fund as established in § 62.1-225, and other financing mechanisms; (iv) water quality conditions; and (v) other relevant factors. Following receipt of the compliance plans required by subdivision C 3, the Board shall reevaluate the schedule taking into account the information in the compliance plans and the factors in this subdivision, and may modify the schedule as appropriate;

3. A requirement that within nine months after the initial effective date of the general permit, the permittees shall either individually or through the Association submit compliance plans to the Department for approval. The compliance plans shall contain, at a minimum, any capital projects and implementation schedules needed to achieve total nitrogen and phosphorus reductions sufficient to comply with the individual and combined waste load allocations of all the permittees in the tributary. The compliance plans may rely on the exchange of point source credits in accordance with this article, but not the acquisition of credits through payments authorized by § 62.1-44.19:18, to achieve compliance with the individual and combined waste load allocations in each tributary. The compliance plans shall be updated annually and submitted to the Department no later than February 1 of each year. The compliance plans due beginning February 1, 2023, shall address the requirements of the ENRC Program;

4. Such monitoring and reporting requirements as the Board deems necessary to carry out the provisions of this article;

5. A procedure that requires every owner or operator of a facility authorized by a Virginia Pollutant Discharge Elimination System permit to discharge 100,000 gallons or more per day, or an equivalent load, directly into tidal waters, or 500,000 gallons or more per day, or an equivalent load, directly into nontidal waters, to secure general permit coverage by filing a registration statement with the Department within a specified period after each effective date of the general permit. The procedure shall also require any owner or operator of a facility authorized by a Virginia Pollutant Discharge Elimination System permit to discharge 40,000 gallons or more per day, or an equivalent load, directly into tidal or nontidal waters to secure general permit coverage by filing a registration statement with the Department at the time he makes application with the Department for a new discharge or expansion that is subject to an offset or technology-based requirement in § 62.1-44.19:15, and thereafter within a specified period of time after each effective date of the general permit. The procedure shall also require any owner or operator of a facility with a discharge that is subject to an offset requirement in subdivision A 5 of § 62.1-44.19:15 to secure general permit coverage by filing a registration statement with the Department prior to commencing the discharge and thereafter within a specified period of time after each effective date of the general permit. The general permit shall provide that any facility authorized by a Virginia Pollutant Discharge Elimination System permit and not required by this subdivision to file a registration statement shall be deemed to be covered under the general permit at the time it is issued, and shall file a registration statement with the Department when required by this section. Owners or operators of facilities that are deemed to be permitted under this section shall have no other obligation under the general permit prior to filing a registration statement and securing coverage under the general permit based upon such registration statement;

6. A procedure for efficiently modifying the lists of facilities covered by the general permit where the modification does not change or otherwise alter any waste load allocation or delivery factor adopted pursuant to the Water Quality Management Planning Regulation (9VAC25-720) or its successor, or an applicable total maximum daily load. The procedure shall also provide for modifying or incorporating new waste load allocations or delivery factors, including the opportunity for public notice and comment on such modifications or incorporations; and

7. Such other conditions as the Board deems necessary to carry out the provisions of this chapter and Section 402 of the federal Clean Water Act (33 U.S.C. § 1342).

D. 1. The Board shall (i) review during the year 2020 and every 10 years thereafter the basis for allocations granted in the Water Quality Management Planning Regulation (9VAC25-720) and (ii) as a result of such decennial reviews propose for inclusion in the Water Quality Management Planning Regulation (9VAC25-720) either the reallocation of unneeded allocations to other facilities registered under the general permit or the reservation of such allocations for future use.

2. For each decennial review, the Board shall determine whether a permitted facility has:

a. Changed the use of the facility in such a way as to make discharges unnecessary, ceased the discharge of nutrients, and become unlikely to resume such discharges in the foreseeable future; or

b. Changed the production processes employed in the facility in such a way as to render impossible, or significantly to diminish the likelihood of, the resumption of previous nutrient discharges.

3. Beginning in 2030, each review also shall consider the following factors for municipal wastewater facilities:

a. Substantial changes in the size or population of a service area;

b. Significant changes in land use resulting from adopted changes to zoning ordinances or comprehensive plans within a service area;

c. Significant establishment of conservation easements or other perpetual instruments that are associated with a deed and that restrict growth or development;

d. Constructed treatment facility capacity;

e. Significant changes in the understanding of the water chemistry or biology of receiving waters that would reasonably result in unused nutrient discharge allocations over an extended period of time;

f. Significant changes in treatment technologies that would reasonably result in unused nutrient discharge allocations over an extended period of time;

g. The ability of the permitted facility to accommodate projected growth under existing nutrient waste load allocations; and

h. Other similarly significant factors that the Board determines reasonably to affect the allocations granted.

The Board shall not reduce allocations based solely on voluntary improvements in nutrient removal technology.

E. The Board shall maintain and make available to the public a current listing, by tributary, of all permittees and permitted facilities under the general permit, together with each permitted facility's total nitrogen and total phosphorus waste load allocations, and total nitrogen and total phosphorus delivery factors.

F. Except as otherwise provided in this article, in the event that there are conflicting or duplicative conditions contained in the general permit and an individual Virginia Pollutant Discharge Elimination System permit, the conditions in the general permit shall control.

G. The Board shall adopt amendments to the Water Quality Management Planning Regulation and modifications to Virginia Pollutant Discharge Elimination System permits or registration lists to establish and implement the Phase III Watershed Implementation Plan Enhanced Nutrient Removal Certainty Program (ENRC Program) as provided in this subsection. The ENRC Program shall consist of the following projects and the following waste load allocation reductions and their respective schedules for compliance.

That the Enhanced Nutrient Removal Certainty Program as established in subdivisions G 1, 2, and 3 of § 62.1-44.19:14 of the Code of Virginia, as amended by this act, shall be deemed to implement through January 1, 2026, the Commonwealth's Chesapeake Bay Phase III Watershed Implementation Plan in lieu of the floating waste load allocation concept proposed in Initiative 52 of the Commonwealth's Chesapeake Bay Phase III Watershed Implementation Plan. However, nothing in this act shall be construed to limit the State Water Control Board's authority to impose (i) additional requirements or modifications to phosphorous waste load allocations necessary to achieve compliance with the numeric chlorophyll-a criteria applicable to the James River; (ii) requirements or modifications to waste load allocations necessary to comply with changes to federal law that become effective after January 1, 2021; or (iii) requirements or modifications to waste load allocations necessary to comply with a court order issued after January 1, 2021.

3. That the State Water Control Board shall modify the Virginia Pollutant Discharge Elimination System (VPDES) permits for the facilities listed in subdivision G 1 of § 62.1-44.19:14 of the Code of Virginia, as amended by this act, to include any requirements and compliance schedules established in this act.

4. That if the Secretary of Natural Resources (the Secretary) determines on or after July 1, 2026, that the Commonwealth has not achieved, or in the event of increased nutrient loads associated with climate change will not be able to maintain, its nitrogen pollution reduction commitments in the Chesapeake Bay Total Maximum Daily Load (TMDL) Phase III Watershed Implementation Plan, the Secretary may develop an additional watershed implementation plan or plans pursuant to § 2.2-218 of the Code of Virginia. Any such plan shall take into consideration the progress made by all point and nonpoint sources toward meeting applicable load and waste load allocations, the best available science and water quality modeling, and any applicable U.S. Environmental Protection Agency guidance for Chesapeake Bay TMDL implementation. In any such plan, the Secretary may include as priority projects upgrades with nutrient removal technology of 4.0 mg/L annual average total nitrogen concentration at municipal wastewater treatment facilities with a design capacity greater than 10.0 MGD discharging to James River Segment JMSTF2 so long as (i) the scheduled date for compliance is January 1, 2036; (ii) notwithstanding the wasteload allocations specified in clause (iii), compliance requires operating the nutrient removal technology to achieve an annual average total nitrogen concentration of less than or equal to 4.0 mg/L or, until such time as the facility is upgraded to achieve such concentration, the option of achieving an equivalent discharged load based on an annual average total nitrogen concentration of 4.0 mg/L and actual annual flow treated, including the use of point source nitrogen credits; and (iii) the facilities have and retain the following total nitrogen waste load allocations: Falling Creek WWTP (182,738 lbs/year), Proctors Creek WWTP (411,151 lbs/year and, in the event that Proctors Creek WWTP is expanded in accordance with 9VAC25-40-70 and Falling Creek WWTP is upgraded to achieve 4.0 mg/L, 493,391 lbs/year), and Henrico County WWTP (1,142,085 lbs/year). If the Secretary opts to include such facilities in the plan, the State Water Control Board shall include the foregoing concentrations limits, waste load allocations, and schedules for compliance in the Water Quality Management Planning Regulation, the Watershed General Virginia Pollutant Discharge Elimination System permit, and individual VPDES permits, as applicable.
