Bill Summary

An act to add Section 116341 to the Health and Safety Code, relating to drinking water.

AI Summary

This bill adds a new section to California's Health and Safety Code that provides temporary relief for public water systems dealing with hexavalent chromium (a potentially toxic form of chromium) contamination. Specifically, the bill prevents a public water system from being considered in violation of the hexavalent chromium drinking water standard while it is implementing a state board-approved compliance plan or while the state board is reviewing its proposed compliance plan. This protection applies only to water systems that already meet the total chromium maximum contaminant level (MCL), which is an enforceable standard that limits the overall amount of chromium in drinking water. The bill does not change the state's overall requirements for establishing drinking water standards, applies only to hexavalent chromium, and does not limit the state board or Attorney General's ability to enforce drinking water regulations. If the state board rejects a water system's compliance plan, the bill's protections will no longer apply. The legislation aims to provide water systems some flexibility in addressing hexavalent chromium contamination while maintaining public health safeguards.
