(a)The supervisor, after consulting with the State Water Resources Control Board and an appropriate regional water quality control board, may authorize the conversion of not more than 250 wells for use as gravity-based energy storage wells pursuant to this article to evaluate their use, including the establishment of appropriate operating conditions and physical parameters to safely store and generate energy.

(b)Before authorizing the use of a well as a gravity-based energy storage well, the supervisor, the State Water Resources Control Board, or an appropriate regional water quality control board may require the operator to provide additional information demonstrating the suitability of the well for use as a gravity-based energy storage well, including, but not limited to, providing an analysis of the chemical composition of the fluid in the wellbore, and may require testing for, among other indicators of suitability, total dissolved solids, total petroleum hydrocarbon as crude oil, major cations, including, but not limited to, calcium, magnesium, sodium, potassium, iron, manganese, strontium, and boron, major anions, including, but not limited to, chloride, sulfate, bicarbonate, carbonate, bromide, and iodide, total alkalinity and hydroxide, electrical conductance, potential of hydrogen or pH, and temperature. Liquid analysis required pursuant to this section shall be performed by a laboratory that is certified by the State Water Resources Control Board’s Environmental Laboratory Accreditation Program. The performing laboratory shall submit the data and analysis directly to the supervisor or the appropriate regional water quality control board, as appropriate, using a digital format, and also to the State Water Resources Control Board, in an electronic format uploaded to their online GeoTracker information system following the applicable regulations adopted pursuant to Section 13197.5 of the Water Code.

(c)The operator, before conversion of a well to a gravity-based energy storage well, shall file with the supervisor a written notice of intention to convert the well to a gravity-based energy storage well. The notice shall contain the pertinent data the supervisor requires in a format acceptable to the supervisor. The supervisor may require other pertinent information to supplement the notice. If conversion has not commenced within 24 months from the approval of the notice, the notice shall be deemed canceled. The notice shall not be extended and the cancellation shall be noted in the division’s records.
