AB 794: California Safe Drinking Water Act: emergency regulations.

The bill aims to improve California's safe drinking water act by expanding the state's authority to adopt emergency regulations. This expansion allows the state to adopt requirements from a specified federal regulation, even if it's less stringent than the federal regulation. The emergency regulations cannot implement less stringent drinking water standards and can include more stringent monitoring requirements. Maximum contaminant levels and compliance dates for these regulations cannot be more stringent than those set by the federal act. The state water resources control board must adopt an emergency regulation by December 31, 2026, and initiate a primary drinking water standard for perfluoroalkyl and polyfluoroalkyl substances by the same deadline.
