To encourage advances in mining and reclamation practices or to allow post-mining land use for industrial, commercial, residential or public use, including recreational facilities, the director may, with the approval by the secretary of the United States department of the interior, authorize departures in individual cases on an experimental basis from the environmental protection standards established under Sections 19 and 20 [69-25A-19 and 69-25A-20 NMSA 1978] of the Surface Mining Act. Such departures may be authorized if :
A. the experimental practices are potentially at least as environmentally protective, during and after mining operations, as the performance standards of Sections 19 and 20 of the Surface Mining Act;B. the mining operations approved for particular land use or other purposes are not larger or more numerous than necessary to determine the effectiveness and economic feasibility of the experimental practices; andC. the experimental practices do not reduce the protection afforded public health and safety below that provided by the performance standards of Sections 19 and 20 of the Surface Mining Act.Laws 1979, ch. 291, § 33.
