The current renewal of the Eckman Park and Mines 1, 2 and 3 South CDPS permit (No. CO-0027154) will contain stormwater provisions. When this renewal becomes effective, certification COR-040076 will be inactivated. Under the terms of the combined individual permit (CO-0027154), the Cyprus Yampa Valley Coal Corporation will be authorized to discharge stormwater associated with industrial activity into waters of the State of Colorado.

A SWMP shall be developed for the portions of Eckman Park and Mines 1 and 2 and 3 South which do not drain to numbered outfalls to which effluent limitations are applied. The plan shall identify potential sources of pollution which may reasonably be expected to affect the quality of stormwater discharges associated with industrial activity. In addition, the plan shall describe and ensure the implementation of practices which are to be used to reduce the pollutants in stormwater discharges associated with industrial activity at the facility and to assure compliance with the terms and conditions of this permit. The Cyprus Yampa Valley Coal Corporation must implement the provisions of the SWMP as a condition of this permit. Contents and requirements of the SWMP are discussed in the Permit at Part I.C.2. c) Compliance Datea: The Eckman Park and Mines 1, 2 and 3 South SWMP shall be submitted to the Division, as soon as possible but no later than .Iuly 1, 1993.
