Water Quality Standards [9 VAC 25 ‑ 260]
Amending the Water Quality Standards regulation to designate four waters as Public Water Supply (PWS) (Eff. Date 11/24/21)
Action 5670
General Information
Action Summary NOTE: EPA has approved the amendments and the effective date in Virginia is 11/24/21. Notice of the effective date will be published in the Virginia Register of Regulations on December 20, 2021. The proposed substantive amendments to sections 9VAC25-260-400; 420; 440; and 510 of the State’s Water Quality Standards would place a public water supply (PWS) notation in the Special Standards column next to the appropriate section of the river basin where the water supply intake is located. Typically, more stringent criteria apply to numerous pollutant parameters to protect the designated use of public water supply for human consumption. Three of the four water supplies are proposed and withdrawal structures are either currently in construction or are planned to be in the immediate future. One is active and all withdrawal structures and appurtenances have been constructed and are currently in use.
