§ 922. Water quality implementation planning and targets
(a) After listing a water as impaired on the list of waters required by 33 U.S.C. § 1313(d), the Secretary shall include in the implementation plan for the water a strategy for returning the water to compliance with the Vermont Water Quality Standards. With respect to a water that is impaired due to sources outside the State or if there is insufficient data or no data available to quantify reductions required by this subchapter, the Secretary shall not be required to implement the requirements of this subchapter; however, the Secretary shall provide an alternate strategy for attaining water quality standards in the implementation plan for the water. For waters determined to be subject to this subchapter, the Secretary shall include the following in an implementation plan:
(1) An evaluation of whether implementation of existing regulatory programs will achieve water quality standards in the impaired water. If the Secretary determines that existing regulatory programs will not achieve water quality standards, the Secretary shall determine the amount of additional pollutant reduction necessary to achieve water quality standards in that water. When making this determination, the Secretary may express the pollutant reduction in a numeric reduction or through defining a clean water project that must be implemented to achieve water quality standards.
(2) An allocation of the pollutant reduction identified under subdivision (a)(1) of this section to each basin and the clean water service provider assigned to that basin pursuant to subsection 924(a) of this title. When making this allocation, the Secretary shall consider the sectors contributing to the water quality impairment in the impaired water’s boundaries and the contribution of the pollutant from regulated and nonregulated sources within the basin. Those allocations shall be expressed in annual pollution reduction goals and five-year pollution reduction targets as checkpoints to gauge progress and adapt or modify as necessary.
(3) A determination of the standard cost per unit of pollutant reduction. The Secretary shall publish a methodology for determining standard cost pollutant reductions. The standard cost shall include the costs of project identification, project design, and project construction.
(b)(1) The Secretary shall conduct the analysis required by subsection (a) of this section for previously listed waters as follows:
(A) For phosphorous in the Lake Champlain watershed, not later than November 1, 2021.
(B) For phosphorous in the Lake Memphremagog watershed, not later than November 1, 2022.
(2) By not later than November 1, 2023, the Secretary shall adopt a schedule for implementing the requirements of this subchapter in all other previously listed impaired waters, including Lake Carmi, not set forth in subdivision (1) of this subsection.
(c) When implementing the requirements of this section, the Secretary shall follow the type 3 notice process established in section 7714 of this title. (Added 2019, No. 76, § 1.)
