<br />CHAPTERTWO Proposed Action and Alternatives ' <br /> <br />2.2.6.2 Stormwater Permits and Stormwater Management Plans <br />Stormwater Dischazge Permits and Stormwater Management Plans (SWMP), which aze covered <br />under the Colorado Discharge Permit System, would apply to the construction of facilities for the <br /> <br />Yankee Gulch Project and may apply to the operation of the Yankee Gulch Proj~:ct at both the , <br />Piceance Site and the Pazachute Site. <br />Construction activities with an azeal extent of greater than 5 acres are required to have a ' <br />Stormwater Discharge Permit and an SWMP. The SWMP must be prepazed before construction <br />begins and must identify Best Management Practices (BMPs) for preventing pollution of surface <br />waters. Submittal of the SWMP is not required, but it must be kept onsite at all times. ' <br />Stormwater Dischazge Permit Applications and SWMPs must be prepared for project operations <br />if stormwater is dischazged off-site. A portion of the stormwater runoff from thc: Piceance Site , <br />processing facility azea would be routed to the evaporation pond. A specific surface drainage <br />plan has not been developed for the remainder of the Piceance Site. At the Parachute Site, <br />stormwater would be managed utilizing existing Unocal facility structures to handle stormwater ' <br />wherever possible. If stotmwater would be discharged off-site at either the Piceance Site or the <br />Parachute Site during project operations, Stormwater Discharge Permit Applications and <br />SWMPs would be prepazed. Annual reports would be submitted to the CDPHE that detail ' <br />compliance with the SWMPs. <br />2.2.6.3 Hazardous Waste Contingency Plans ' <br />Operation of the Yankee Gulch Project would not generate hazardous wastes. Therefore, a <br />Hazardous Waste Contingency Plan would not be required. Nonhazardous wastes such as boiler ' <br />blowdown, cooling tower blowdown, particulate filter backwash, and reverse osmosis <br />concentrate would be dischazged to onsite evaporation ponds. , <br />2.2.6.4 Emergency Planning and Community Right•to-Know <br />Under the Emergency Planning and Community Right-to-Know Act of 1986, the federal ' <br />government requires that detailed information about the nature of hazardous substances in or near <br />communities be made available to the public. American Soda would submit Material Safety ' <br />Data Sheets to appropriate agencies prior to commencing operations, and, if required, reporting <br />requirements would be met. <br />2.2.6.5 Other Plans ' <br />American Soda would continually review regulatory requirements throughout the life of the ' <br />Yankee Gulch Project and would add plans and procedures as necessary. All plums and <br />procedures would be developed in coordination with the BLM. <br />2.2.7 Reclamation ' <br />In general, American Soda would reclaim disturbed surfaces at the Yankee Gulch Project in ' <br />accordance with the BLM's Mitigation Measures and Conditions of Approval for the <br />2-24 ' <br />
