Action 3522
General Information
Action Summary [EPA Approved January 6, 2020. Effective date notice filed with the Virginia Register of Regulation on January 9, 2020.] The purpose of this rulemaking is to consider amending site specific numeric chlorophyll criteria for the tidal James River. The intent of this rulemaking is to protect designated and beneficial uses of the tidal James River by amending or adopting regulations that are technically correct, reasonable, and necessary. These standards will be used in setting Virginia Pollutant Discharge Elimination System Permit limits and for evaluating the waters of the Commonwealth for inclusion in the Clean Water Act 305(b) report and on the 303(d) list. Amending the chlorophyll criteria for the tidal James River may result in amending that portion of the December 2010 Chesapeake Bay Total Maximum Daily Load allocations for nitrogen, phosphorus, and sediment in the James River basin. This rulemaking is warranted given the addition of new information related to algal communities and their relationship to designated and beneficial use. The goals of the new or amended regulation will be to ensure protection of designated and beneficial uses of the tidal James River through the best science and regulatory approaches.
