Section 74:29:11:58 - Ground water contamination during the postclosure period
Current through Register Vol. 50, page 114, March 25, 2024
Ground water contamination detected during the postclosure period shall be confirmed by additional sampling conducted by the operator as required by the department and shall be evaluated to determine whether remedial action is required. The remedial action required by the operator depends upon the extent of the impact, based upon the following:
(1) Whether the impact is a result of the mining operation;
(2) The impacts to the health and well being of the people, animals, wildlife, aquatic life, and plant life affected;
(3) The social and economic value of the impacted aquifer;
(4) The technical practicability and economic reasonableness of reducing or eliminating the source of pollution;
(5) The effect upon the environment; and
(6) The potential impacts to other waters of the state.
Based upon the evaluation, the department shall determine whether remedial action is required. If the department determines remedial action is required, the operator shall submit a remedial action plan. Depending upon the severity of the impact, the remedial actions may range from additional monitoring to a resumption of ground water restoration activity. The postclosure financial assurance shall be recalculated to account for the cost of remedial actions.
