Pub. Resources Code, § 2770.6

(a) Whenever surface mining operations are proposed within the boundaries of the San Gabriel Basin Water Quality Authority that may penetrate the groundwater, and whenever proposed reclamation activities may impact groundwater quality, the lead agency reviewing an application to conduct surface mining operations, or reviewing an application for the approval of a reclamation plan, shall notify and provide copies of the subject application to the appropriate California regional water quality control board, and any watermaster for the groundwater recharge basin. Notwithstanding any other provision of law, the appropriate California regional water quality control board may impose an administrative fee on the applicant to cover its costs associated with the review of, and preparation of, comments on the subject application, as required pursuant to this section.

(b) Each agency shall have 60 days to review and comment on the proposed surface mining operation described in subdivision (a) and the adoption of any reclamation plan therefor. Each agency shall comment on the existing groundwater quality and the potential impacts to water quality that may result from the mining operations and the proposed reclamation plan, and shall recommend methods and procedures to protect groundwater quality and prevent groundwater degradation. Each agency shall also comment on the proposed mining activities, including the conduct of excavation and backfilling operations in contact with groundwater, and the impact of any proposed alternative land uses on groundwater quality. When the proposed surface mining operations or reclamation plan will impact the groundwater, the lead agency shall not approve the reclamation plan without requiring actions to ensure the reasonable protection of the beneficial uses of groundwater and the prevention of nuisance. Each agency shall have 60 days to review and comment or until 60 days from the date of application, whichever occurs first.

(c) This section applies to activities otherwise subject to this chapter conducted within the boundaries of the San Gabriel Basin Water Quality Authority. To the extent of any conflict between this section and any other provision of this chapter, this section shall prevail.
