PART I Page 5 of 20 Permit No. COR-040000 A. COVERAGE UNDER THIS PERMIT (cont.) 5. Individual Permit Criteria Aside from the operation type, the Division may use other criteria in evaluating whether an individual permit is required instead of this general permit. This information may come from the application, SWMP, or additional information as requested by the Division, and includes, but is not limited to, the following: a. the quality of the receiving waters (i.e., the presence of downstream drinking water intakes or a high quality fishery, or for preservation of high quality water); b. the type of mining operation, including pollution potential; c. the volume and type of materials handled; d. the size of the facility; e. evidence of noncompliance under a previous permit for the operation; f. the use of chemicals within the stormwater system. In addition, an individual permit may be required when the Division has shown or has reason to suspect that the stormwater discharge is a significant contributor of pollutants to waters of the State. 6. Permit Expiration Date Authorization to discharge under this general permit shall expire on September 30, 2001. The Division must evaluate and reissue this general permit once every five years and must recertify the applicant's authority to discharge under the general permit at such time. Any permittee desiring continued authorization under the general permit must reapply by June 30, 2001. The Division will determine if the applicant may continue to operate under the terms of the general permit. An individual permit will be required for any facility not reauthorized to discharge under the reissued general permit. B. STORMWATER MANAGEMENT PLAN - ACTIVE MINES A Stormwater Management Plan (SWMP) shall be developed for the portion of each facility covered by this permit. The SWMP shall be prepared in accordance with good engineering practices. (The plan need not be completed by a registered engineer.) The plan shall identify potential sources of pollution (including sediment) which may reasonably be expected to affect the quality of stormwater discharges associated with the mining operation. In addition, the plan shall describe and ensure the implementation of best management practices (BMPs) which will be used to reduce the pollutants in stormwater discharges associated with mining activity and to assure compliance with the terms and conditions of this permit. Permittees must implement the provisions of their SWMP as a condition of this permit. The Division reserves the right to review the plan, and to require additional measures to prevent and control pollution as needed. SWMPs which met criteria in the previous version of this permit are acceptable. The SWMP for active mines shall include the following items, at a minimum: 1. Description of Mining Activities The plan shall provide a narrative description of the mining and associated activities taking place at the site which affect or may affect stormwater runoff intended to be covered by this permit. The narrative description shall report the total acreage within the mine site and an estimate of the number of acres of disturbed area. A general description of the location of the mining site relative to major transportation routes and communities shall also be provided.
