CA SB466

Public water systems meeting the total chromium maximum contaminant level (MCL) standard cannot be held in violation of the hexavalent chromium drinking water standard while implementing a State Water Resources Control Board-approved compliance plan

Water systems that have submitted a compliance plan for approval are also protected from violation determinations while the state board's decision is pending

The exemption does not apply if the state board rejects the hexavalent chromium MCL compliance plan

The bill does not affect the state's authority to establish drinking water standards or apply to any contaminants other than hexavalent chromium

The State Water Resources Control Board and Attorney General retain authority to enforce applicable laws and regulations regarding hexavalent chromium, including approved compliance plans
