Legislation (SB 385)

On Sept 4, Governor Edmund Brown Jr. signed into law SB 385, legislation that empowers the State Water Resources Control Board (SWRCB) to grant public water agencies a compliance period for meeting California’s chromium-6 drinking water standard. Agencies must meet stringent requirements to receive the state board’s compliance period. CVWD has been diligently preparing the materials necessary to obtain the compliance period from the SWRCB as SB 385 worked its way through the state Legislature and to the Governor for his signature.
