SB 1259: Refineries: decommissioning and remediation: cost estimates.

<p>The proposed legislation requires refineries in California to submit draft reports detailing decommissioning and site remediation costs by December 31, 2028. The State Water Resources Control Board must initiate a public comment period and may hold hearings on these reports. Unless trade secrets are claimed, all submitted information must be made publicly available. Refiners planning permanent shutdowns or reconfigurations must also submit draft reports within specified timeframes. By December 31, 2027, the board is tasked with developing guidelines for estimating remediation costs and timelines. The State Energy Resources Conservation and Development Commission will use this information to assess total decommissioning and remediation liabilities for California's refineries.</p>
