LAC 43:XV.5303. Casing and Sealing of Drilled Holes: General Requirements

A. Each exploration hole, other drill or borehole, well or other exposed underground opening shall be cased, sealed or otherwise managed, as approved by the office, to prevent acid or other toxic drainage from entering the ground water or surface water, to minimize disturbance to the prevailing hydrologic balance and to ensure the safety of people, livestock, fish and wildlife, and machinery in the mine plan and adjacent area. If these openings are uncovered or exposed by surface mining activities within the permit area, they shall be permanently closed, unless approved for water monitoring, or otherwise managed in a manner approved by the office. Use of a drilled hole, borehole or monitoring well as a water well must meet the provisions of §5341. This Section does not apply to holes solely drilled and used for blasting.
