The California Safe Drinking Water Act provides for the operation of public water systems and imposes on the State Water Resources Control Board various duties and responsibilities for the regulation and control of drinking water in the State of California. The act requires the state board to adopt primary drinking water standards for contaminants in drinking water based upon specified criteria, and requires a primary drinking water standard to be established for hexavalent chromium. Existing law authorizes the state board to grant a variance from primary drinking water standards to a public water system.
This bill would prohibit a public water system that meets the total chromium maximum containment level (MCL) enforceable standard for drinking water in California from being determined, held, considered, or otherwise deemed in violation of the primary drinking water standard for hexavalent chromium while implementing a state board approved compliance plan or while state board action on the proposed and submitted compliance plan is pending, as provided.
