r <br />' APPENDIX C (cont.) <br />requesting agency within the time frame specified in the request. Those portions of the referenced <br />documents must be included in the submittal. The SWMP must also be readily available to an on- <br />site inspector. <br />INACTIVE MINES <br />The SWMP shall include the following items, at a minimum: <br />1. Description of Mining Activities <br />The plan shall provide a narrative description of the mining and associated activities that took place <br />at the site. The narrative description shall report the approximate dates of operation, the total <br />acreage within the mine site and an estimate of the number of acres of disturbed area. A general <br />description of the location of the mining site relative to major transportation routes and communities <br />shall also be provided. <br />2. Site Mau <br />Each plan shall provide a generalized site map or maps which indicate any of the following which <br />may be applicable: <br />- mining/milling site boundaries and access and haul roads; <br />- areas used for storage of overburden, materials, soils, tailings or wastes; <br />- areas used for outdoor manufacturing, storage or disposal of materials; <br />- tailings piles and ponds; <br />- an estimate of the direction(s) of surface flow; <br />- existing structural control measures to reduce pollutants in Stormwater runoff; and <br />- springs, streams, wetlands and other surface waters. <br />3. Stormwater Management Controls -Identification of Sources and Best Management Practices <br />The SWMP shall identify potential sources of pollutants at the site and assess the potential of these <br />sources to contribute pollutants to Stormwater discharges associated with mining activities. The <br />SWMP must also describe appropriate Best Management practices (BMPs) to reduce the potential of <br />these sources to contribute pollutants to Stormwater discharges. The appropriateness and priorities of <br />controls in the plan shall reflect identified potential sources of pollutants at the mining site. The <br />description of the BMPs shall include: <br />a. Stormwater diversion: Describe how and where Stormwater will be diverted away from potential <br />pollutant sources to prevent Stormwater contamination. <br />b. Sediment and erosion prevention: Describe practices that will be used to reduce erosion and <br />prevent sediment delivery to State waters. These could include structural (such as silt fences, <br />sediment ponds, drop structures, check dams) and non-structural (such as mulching and <br />revegetation) methods. <br />4. Comprehensive Inspection and Record Keening Procedures <br />The SWMP shall identify qualified personnel that shall inspect designated areas. Inspections required <br />by this part shall be conducted annually. Where annual inspections are impracticable, certification <br />once every three years by a Registered Professional Engineer that the site is in compliance with the <br />SWMP, is required. The SWMP shall also identify procedures for recordkeeping and internal <br />reporting. <br />7/96/Ihm C-4 <br />
