Additionally, Elam has developed Imported Soil Acceptance Protocol and Soil Sampling <br />Protocol documents (revised September 1, 2006 and included in Appendices B and C, <br />respectively). The Imported Soil Acceptance Protocol details which types of soil materials <br />are specifically excluded from acceptance at the Pit; for example, mining waste, asbestos <br />materials, solid wastes, hydrocarbon-impacted soils, etc. The Soil Sampling Protocol <br />provides internal guidance for Elam's routine sampling procedure for the imported soil <br />stockpile(s). Elam shall collect soil samples, one for every 20,000 cubic yards of imported <br />material, with a minimum of one soil sample on a quarterly basis to monitor stockpile <br />conditions in order to minimize the chance of future environmental contamination at the Pit. <br />2.5 EROSION AND SEDIMENT CONTROL <br />Elam will implement and maintain erosion prevention and sediment control systems to <br />minimize the transport of soil particles into surface waters at/near the Pit. Berms, ditches, <br />and/or silt fencing may be utilized to accomplish this goal. <br />Stormwater discharges from Pit operations (including sand & gravel mining and asphalt & <br />concrete batch plants) comply with the Colorado Discharge Permit System regulations. Elam <br />has the required general permits and Stormwater Management Plans (SWMPs) in place for <br />the Pit and asphalt plant. Annual reports are submitted to CDPHE, and bi-annual inspections <br />are performed at the Pit. All stormwater runoff is contained onsite and no process water or <br />mine water is discharged at the Pit; therefore, no discharge monitoring is required for the <br />site. <br />2.6 OTHER ENVIRONMENTAL ISSUES <br />Air Quality - Air emissions from pit operations (aggregate crushing, asphalt & concrete <br />production, and fugitive dust from haul roads) comply with CDPHE Air Quality Control <br />Division (APCD) regulations. Elam has the necessary APCD permits and control plans in <br />place for the Pit, crusher, and asphalt plant. <br />Landfills - Elam does not perform any on-site landfilling of solid waste at the Pit. <br />Hazardous Waste - No hazardous waste is generated or stored at the Pit. <br />Vagneur Pit- WRPP 8 September 1, 2006
