PART I - Page 7 Permit No. COG-850000 • B. EFFLUENT LIPIITATIONS AND MONITORING REQUIREMENTS 2. Stormwater Management Plan (continued) In the areas of coal mining facilities directly regulated by effluent limitations, it is expected chat, through actions directed at achieving compliance with these limitations, the permittee will effectively control most site stormwacer discharges. However, in ocher areas, this may not be the case. Some of the discharges are outside the coverage of the diversion ditches and sedimentation ponds required under the facility's Colorado Mined Land Reclamation Division (CMLRD) permit. Examples of such areas are roads and railroad lines used for transportation to and from the site, oucslopes of ponds, inactive loadouts, sites used for storage and maintenance of material handling equipment and areas granted small area exemptions. The plan shall describe all areas that have not been previously permitted, but meet the definition of a stormwater discharge in 40 CFR 122.26, and shall include a map (or maps) denoting the affected areas. The map(s) shall show the location of the discharge(s) or drainage areas and indicate the receiving waters. The map(s) shall label each stormwater outfall with a three digit number beginning with the next number after the last numher assigned to surface runoff outfalls. The plan shall describe the controls and/or procedures that • specifically address the goal of minimizing or eliminating the pollution from these scurces. In some cases, this may entail construction of physical facilities. In other cases, it may entail developing new methods of operation or material handling and/or replacement of materials with those that are less polluting. The permittee shall make the appropriate determinations and receive the appropriate approvals from the CMLRD. Where necessary, the plan shall include a schedule of activities and/or construction with a reasonable timetable for implementation of any new operations or construction of new facilities necessary to achieve the required goals. The timetable shall allow for attainment of operational level as expediently as possible, but in no case after June 30, 1995, in conformance with Part 402(p)(4)(A) of the Federal Clean Water Act. The Division will ensure that no proposed timetable is excessively lengthy. Specific Requirements: a) A coov of the olan shall be kept on-site and shall be readily available [o all personnel involved with compliance with the plan. b) The plan shall contain a statement of certification, signed by cop management, supporting compliance with the stated goals. • c) Records pertaining to implementation of the plan shall be kept in a log and made available on request to Division, CMLRD and EPA representatives (see Part I.C.4.).
