SB 1433: Gravity-Based Energy Storage Well Pilot Program.

Existing law requires the State Oil and Gas Supervisor to supervise the drilling, operation, maintenance, and abandonment of wells so as to prevent damage to life, health, property, and natural resources, damage to underground oil and gas deposits from infiltrating water and other causes, loss of oil, gas, or reservoir of energy, and damage to underground and surface waters suitable for irrigation or domestic purposes by the infiltration of, or the addition of, detrimental substances. Existing law defines wells to mean oil or gas wells or other wells related to oil or gas production.

Under existing law, a person who fails to comply with the requirements relating to the regulation of wells is guilty of a misdemeanor.

This bill would, until January 1, 2034, establish the Gravity-Based Energy Storage Well Pilot Program and would authorize the supervisor to authorize the conversion of not more than 1,000 wells for use as gravity-based energy storage wells, as defined, to evaluate their use, including the establishment of appropriate operating conditions and physical parameters to safely generate energy. The bill would require idle wells that are authorized for use as gravity-based energy storage wells to be identified as gravity-based energy storage wells in a plan or updates to the plan required to be filed with the supervisor. The bill would require the mechanical integrity of gravity-based energy storage wells to be assessed by the Geologic Energy Management Division not less than annually. The bill would require an operator of a gravity-based energy storage well, in the event of a loss of mechanical integrity of the well or a leak to the environment, to notify the division, the State Air Resources Board, the appropriate regional water quality control board, and schools and community members within 3,200 feet of the well. The bill would require gravity-based energy storage wells to be continuously monitored for fluid leaks. The bill would specify that the authorization for wells to be used as gravity-based energy storage wells end at the termination of the pilot program. The bill would, by January 1, 2032, require the Secretary for Environmental Protection, in consultation with certain entities, to evaluate the pilot program and make recommendations to the Legislature for a framework to implement an ongoing Gravity-Based Energy Storage Well Program to regulate the operation of gravity-based energy storage wells.

Because a violation of the requirements of the Gravity-Based Energy Storage Well Pilot Program would be a crime, this bill would impose a state-mandated local program.

This bill would prohibit the supervisor from authorizing or allowing the use of a well or hydrocarbon reservoir for any purpose other than provided for in law.

The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.

This bill would provide that no reimbursement is required by this act for a specified reason.
