BILL NUMBER: AB 358INTRODUCED BILL TEXT INTRODUCED BY Assembly Member Smyth FEBRUARY 10, 2011 An act to amend Section 25296.30 of the Health and Safety Code, relating to hazardous substances. LEGISLATIVE COUNSEL'S DIGEST AB 358, as introduced, Smyth. Hazardous substances: underground storage tanks. Existing law generally regulates the storage of hazardous substances in underground storage tanks, including requiring underground storage tanks that are used to store hazardous substances to meet certain requirements. Existing law requires the State Water Resources Control, in consultation with the former State Department of Health Services, to develop guidelines for the investigation and cleanup of methyl tertiary-butyl ether (MTBE) and other ether-based oxygenates in groundwater, with regard to these tanks. This bill would update an obsolete reference and instead require consultation with the State Department of Public Health. Vote: majority. Appropriation: no. Fiscal committee: no. State-mandated local program: no. THE PEOPLE OF THE STATE OF CALIFORNIA DO ENACT AS FOLLOWS: SECTION 1. Section 25296.30 of the Health and Safety Code is amended to read: 25296.30. (a) The board, in consultation with the State Department of Public HealthServices, shall develop guidelines for the investigation and cleanup of methyl tertiary-butyl ether (MTBE) and other ether-based oxygenates in groundwater.
