(1) The regional board or local agency shall notify the board of the planned corrective action.

The regional board or local agency shall obtain approval of the corrective action and the cost estimate before taking, or contracting for, any corrective action.

(b) If the board approves the request of the regional board or local agency made pursuant to paragraph (2) of subdivision (a), the board shall, after making the determination specified in subdivision (c), pay for the costs of corrective action performed by a regional board, local agency, or qualified contractor.

(c) The board shall not make any payment pursuant to subdivision (b) unless the board determines that the owner, operator, or other responsible party of the tank has failed or refused to comply with a final order for corrective action issued pursuant to Section 25296.10 with respect to the unauthorized release of petroleum from the tank.

(d) Upon making any payment to a regional board or local agency pursuant to subdivision (b), the board shall recover the amount of payment pursuant to Section 25299.70.
