2020 SESSION
20105450DBe it enacted by the General Assembly of Virginia:
1. That § 62.1-44.19:21 of the Code of Virginia is amended and reenacted as follows:
§ 62.1-44.19:21. Nutrient credit use by regulated entities.
A. An MS4 permittee may acquire, use, and transfer nutrient
credits for purposes of compliance with any waste load allocations established
as effluent limitations in an MS4 permit issued pursuant to § 62.1-44.15:25.
Such method of compliance may be approved by the Department following review of
a compliance plan submitted by the permittee that includes the use of nutrient
credits. The permittee may use such credits for compliance purposes only if (i) the credits,
(i) whether annual, term, or perpetual, are generated and
applied for purposes of compliance for the same calendar year; (ii) the credits are acquired no later
than a date following the calendar year in which the credits are applied as
specified by the Department consistent with the permittee's Virginia Stormwater
Management Program (VSMP) permit annual report deadline under such permit;
(iii) the credits are generated in
the same locality or tributary, except that permittees in the Eastern Coastal
Basin may also acquire credits from the Potomac and Rappahannock tributaries;
and (iv) the credits either
are either (a) point source
nitrogen or point source phosphorus credits generated by point sources covered
by the general permit issued pursuant to § 62.1-44.19:14,
or are
(b) certified pursuant to § 62.1-44.19:20. An MS4 permittee
may enter into an agreement with one or more other MS4 permittees within the
same locality or within the same or adjacent eight-digit hydrologic unit code
to collectively meet the sum of any waste load allocations in their permits.
Such permittees shall submit to the Department for approval a compliance plan
to achieve their aggregate permit waste load allocations.
B. Those applicants An applicant required to
comply with water quality requirements for land-disturbing activities operating
under a General VSMP Permit for Discharges of Stormwater from Construction
Activities or a Construction Individual Permit may acquire and use perpetual
nutrient credits certified and registered on the Virginia Nutrient Credit
Registry in accordance with § 62.1-44.15:35. If
the applicant is the owner or operator of a publicly owned treatment works that
is a permitted facility under the Watershed General Virginia
Pollutant Discharge Elimination System (VPDES) Permit
issued pursuant to § 62.1-44.19:14 and the applicant's land-disturbing activity
is for the purpose of constructing or expanding the treatment works, wastewater
collection system, or
other facility used for public wastewater utility operations, the applicant may
also generate and use point source nutrient credits by operation of its own
permitted facilities, so long as (i)
notice is given to the Department and (ii) a ratio of 10
point source nitrogen credits for each point source phosphorus credit used is
also transferred and applied toward the land-disturbing project.
C. Confined A combined animal feeding operations
operation issued permits a permit pursuant to this
chapter may acquire, use, and transfer credits for compliance with any waste
load allocations contained in the provisions of a
Virginia Pollutant Discharge Elimination System (VPDES) VPDES permit. Such method of
compliance may be approved by the Department following review of a compliance
plan submitted by the permittee that includes the use of nutrient credits.
D. Facilities A facility registered under
the Industrial Stormwater General Permit issued pursuant to this chapter may acquire,
use, and transfer credits for compliance with any waste load allocations
established as effluent limitations in a VPDES permit. Such method of
compliance may be approved by the Department following review of a compliance
plan submitted by the permittee that includes the use of nutrient credits.
E. Public notice of each compliance plan submitted for approval pursuant to this section shall be given by the Department.
F. This section shall not be construed to limit or otherwise affect the authority of the Board to establish and enforce more stringent water quality-based effluent limitations for total nitrogen or total phosphorus in 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.
