30 C.F.R. § 905.700
(e) The following provisions of California law generally provide for more stringent land use and environmental control and regulation of some aspects of surface coal mining operations than do the provisions of the Surface Mining Control and Reclamation Act of 1977, and the regulations in this chapter. Therefore, pursuant to section 505(b) of SMCRA, these provisions shall not generally be considered to be inconsistent with SMCRA unless, in a particular instance, the Federal program regulations establish more stringent environmental or land use controls:
(f) The following are the California laws that generally interfere with the achievement of the purposes and requirements of SMCRA and are, in accordance with section 504(g) of SMCRA, preempted and superseded. Other California laws may in an individual situation interfere with the purposes and achievements of SMCRA and may be preempted and superseded with respect to the performance standards of §§ 905.815 through 905.828 as they affect a particular coal exploration or surface mining operation by publication of a notice to that effect in the Federal Register.
