Public Resources Code section 3403.6

(a)

For the purposes of this section, “gravity-based energy storage well” has the same meaning as set forth in Section 3190.

(b)

To support the regulatory effort of the supervisor, there shall be imposed an annual charge on operators of gravity-based energy storage wells to defray the regulatory costs incurred by the state in maintaining surveillance of these wells, ensuring that testing is conducted properly, and ensuring that no damage occurs to the environment by reason of conversion. Each gravity-based energy storage well operator shall pay a proportionate share of the total regulatory costs for each fiscal year based on the operator’s number of gravity-based energy storage wells. For each gravity-based energy storage well, the portion owed by the operator shall be computed by dividing the statewide sum of reasonably incurred regulatory costs across all gravity-based energy source wells by the number of gravity-based energy storage wells.

(c)

This section shall remain in effect only until January 1, 2035, and as of that date is repealed.
