Cessation Order No.: C-88-017 Nature of Condition, Practice, or Violation: Failure to adhere to the conditions of the permit thus violating the permit and causing or being reasonably expected to cause significant environmental harm to land, air, or water resources. Failure to maintain a support facility to prevent damage to fish, wildlife, and related environmental values, Failure to conduct surface coal mining operations to minimize disturbances and adverse impacts of the operations on fish, wildlife, and related environmental values. Specifically, a flocculant or coagulant not described in the permit application nor approved in the permit was used by the operator as part of the treatment of mine water prior to its discharge into the natural surface water drainage system. This flocculant or coagulant or other additive to the mine water in the treatment facility was then directly discharged in company with the mine water in quantities lethal to fish resident in that natural surface water drainage system. Act or Permit Provision(s) Violated: Act Section(s): 34-33 subsections 108(1), 114 (2 )(e)(I)(B), 120(1), 120(2)(j) and (X ), 121 (2)(i) and (k ), and 123(1).

Findings - The condition, practice or violation is causing or can reasonably be expected to cause significant imminent environmental harm to land, air, or water resources. Operation(s) to be Ceased Immediately: The use of any unapproved additive, including flocculant or coagulant, by unapproved means in the treatment of mine water before its discharge. Steps Necessary to Abate Cessation Order No. C-88-017 Step 1: Institute a water quality monitoring program for the mine water discharge, Ciruela Canyon, and the Purgatorie River. For comparative purposes and in order to establish the current and future character of the aquatic environment within and adjacent to the permit area, samples are to be taken immediately and at 14-day or shorter intervals thereafter of 1), the mine water being discharged from the treatment ponds at sampling point MDGE-1; 2), tlne water in the Ciruela Canyon drainage at established sampling points CCS-1 and CCS-2, and 3). the water in the Purgatorie River at established sampling points PRS-2 and PRS-3. The samples are to be promptly submitted for immediate analysis by whatever laboratory or facility ' approved by the Division as competent to do so to determine the presence and concentrations of any additives previously employed in the mine water treatment
