NR 182.109 NR 182.109 Plan of operation.

NR 182.109(1) (1) No person may establish or construct a mining waste site or expand an existing mining waste site until a plan of operation has been submitted to the department in accordance with this section and approved in writing by the department. No person may establish, construct, operate, maintain, close, provide long-term care for, or terminate a mining waste facility except in accordance with the approved plan of operation. The plan of operation shall be prepared and submitted to the department in accordance with s. NR 182.104. The plan of operation shall be submitted at the same time as the permit application and plans submitted under ch. NR 131 or 132 and shall be consistent with the applications and plans submitted under ch. NR 131 or 132. For new facilities on permitted mining or prospecting sites, a person may submit a plan of operation with the feasibility report or at any time after the feasibility report is submitted. No person may submit a plan of operation for a facility prior to the time the person submits a feasibility report to the department for that facility. If the proposed waste site is a surface mine backfilled with mining waste, a person may satisfy the requirements for submitting the plan of operation under this section by including the information required by this section in the mining permit application submitted to the department under ch. NR 132 and issuance by the department of the mining permit shall constitute approval of the plan of operation requirements.
