30 CFR Part 817 - PERMANENT PROGRAM PERFORMANCE STANDARDS—UNDERGROUND MINING ACTIVITIES

We, the Office of Surface Mining Reclamation and Enforcement (OSMRE or OSM), are proposing to revise our regulations, based on, among other things, advances in science, to improve the balance between environmental protection and the Nation's need for coal as a source of energy. This proposed rule would better protect streams, fish, wildlife, and related environmental values from the adverse impacts of surface coal mining operations and provide mine operators with a regulatory framework to avoid water pollution and the long-term costs associated with water treatment. We propose to revise our regulations to clearly define “material damage to the hydrologic balance outside the permit area” and require that each permit specify the point at which adverse mining-related impacts on groundwater and surface water would reach that level of damage; collect adequate premining data about the site of the proposed mining operation and adjacent areas to establish an adequate baseline for evaluation of the impacts of mining and the effectiveness of reclamation; adjust monitoring requirements to enable timely detection and correction of any adverse trends in the quality or quantity of surface water and groundwater or the biological condition of streams; ensure protection or restoration of perennial and intermittent streams and related resources; ensure that permittees and regulatory authorities make use of advances in science and technology; ensure that land disturbed by mining operations is restored to a condition capable of supporting the uses that it was capable of supporting before mining; and update and codify the requirements and procedures for protection of threatened or endangered species and designated critical habitat. The proposed changes would apply to both surface mines and the surface effects of underground mines. The majority of the proposed revisions update our regulations to incorporate or reflect the best available science and experience gained over the last 30 years. Approximately thirty percent of the proposed rule consists of editorial revisions and organizational changes intended to improve consistency, clarity, accuracy, and ease of use.
