NAC445A.914. Placement of wells for monitoring Class III wells.

For Class III wells the Director may require that monitoring wells be completed in the zone for injection and in any underground source of drinking water above the zone for injection which could be affected by the operation of the mine. The wells must be located to detect any movement of injected fluids, by-products of the mining process or fluids in the formation outside the mining area. If the operation may be affected by subsidence or catastrophic collapse, the monitoring wells must be located so that they will not be physically affected by those events.
