1.0 - INTRODUCTION <br />This construction stormwater management plan (SWMP) is intended to provide <br />the information and guidance necessary to support the State of Colorado general Permit <br />for Storrnwatcr discharges associated with gravel and surface mining activities at the <br />Sheehan Pit, Moffat County, Colorado. 'The pritnary objective of this SWMP is to <br />identify Best Management Practices (I3MPs) which, when implemented, will meet the <br />terms and conditions of the general permit. 'The overall goal of the SWMP is to maintain <br />surface -water quality by reducing pollutants in stormwater discharges. The intent of a <br />fully implemented SWMP is to achieve compliance with Best Available Technology <br />(BAT) and Best Convention Technology (BCT), as mandated by the Federal Clean Water <br />Act. This SWMP identifies potential sources of stormwater discharges associated with <br />the mining activities and describes the methods of implementing I3MPs. All I3MPs at the <br />site will be temporary and will be moved in conjunction with the advance of mining <br />activities (except for road ditches). <br />This SWMP contains the following sections: Site description in Section 2; BMPs <br />for Stormwater Pollution Prevention including structural and non-structural controls in <br />Section 3; Final Stabilization and Long -Term Stormwater Management in Section 4; <br />Other Controls at the site in Section 5; and Inspection and Maintenance procedures in <br />section 6. <br />WestWater Engineering APPENDIX C - 25 July 2012 <br />
