NAC445A.429. Procedures required to prevent release of contaminants; requirements concerning impoundments.

     1. The holder of the permit must institute appropriate procedures to ensure that all mined areas do not release contaminants that have the potential to degrade the waters of the State.

     2. Open pit mines must, to the extent practicable, be free-draining or left in a manner which minimizes the impoundment of surface drainage and the potential for contaminants to be transported and degrade the waters of the State.

     3. Bodies of water which are a result of mine pits penetrating the water table must not create an impoundment which:

     (a) Has the potential to degrade the groundwaters of the State; or

     (b) Has the potential to affect adversely the health of human, terrestrial or avian life.

     4. The holder of a permit may apply to the Commission to establish a beneficial use with a level of protection less than that required by paragraph (b) of subsection 3 for water impounded in a specific mine pit.
