This berm must be <br />' constructed along the 6460 contour for approximately 1,000 feet." With the berm in <br /> place and maintained as required by the Eagle County Special Use Permit and the Mined <br /> Land Reclamation Permit, there shou]d be zero surface water dischazge for up to the 100- <br />' year storm event. <br /> Materials Handling aad Spill Prevention... <br />' The amount of fuel stored on-site shall be reasonable to support daily operations. Extra <br />unnecessary tanks shall be removed from the site and used elsewhere or disposed of <br /> properly. Empty tanks and drums shall be refilled or disposed of properly. <br /> Waste oil can be beneficially used as burner fuel at the B&B asphalt plant located near <br /> Edwazds, Colorado. The waste oil will be burned to generate heat for the processing of <br /> asphalt. The use of waste oil for heat energy is performed in compliance with air <br />' pollution emission standards by filtering the exhaust air through an efficient bag house <br /> filtration system. <br /> Section E of the SWMP describes the measures to be employed to reduce the potential <br /> for stormwater contamination. <br /> Uther Pollution Prevention Measures <br />' At this time, other Best Management Practices (SNP's) are not proposed beyond those <br /> described above. The operator of this facility shall review water quality data obtained <br />' from site monitoring and may, at his discretion, implement other control measures. If <br /> additional BMP's or modifications to the stormwater project plan are required, these <br /> changes will be noted in the annual report to the CDOH. <br />
