Preparatory Activities <br />Access to the site will be developed off of Thompson Park Road, which is a Park County public <br />road. The access road to the site is proposed to be approximately 1,050 feet in length by 30 <br />feet wide. An 18" culvert will be installed at the entry point next to the county road. A fence <br />would be constructed around the site area and a gate would be installed at the entry off of <br />Thompson Park Road. <br />In addition to processing equipment and material stockpiles in the site area, an office material <br />storage area and tool shed, will be located in the southwest part of the site. The office <br />trailer /secondary trailer will house the plant manager or night watchman. <br />A septic system will be installed at the request of the Park County Environmental Health <br />Department to handle office trailer water (toilet /shower). A permit through the county will be <br />required. <br />A storm water permit with the State of Colorado will also be pursued as needed, although no <br />runoff is anticipated to leave the site due to grades and perimeter berming. <br />The only hazardous substances proposed for use with this project are petroleum based products. <br />A fuel tank and used oils stored in 55 gallon drums will be placed in a shallow pit lined with <br />heavy plastic that is designed to hold contents released from all of the containers. These <br />substances will be located in the southwest part of the site. If a spill over 25 gallons in size <br />occurs, BLM and the hazards spill hotline would be contacted. Any contaminated soil would <br />be dug up, stored and disposed of offsite, in accordance with State regulations. No smoking <br />signs will be posted within 50 feet of the lined pit. A diesel generator will be used to run the <br />wash plant and equipment pertaining to the use of washing and screening of gravel. No <br />permitting is required for use of these substances onsite. <br />The applicant intends to monitor noise levels at the site during full capacity operation of the <br />mine. Noise level information will also be periodically collected by the Mine Safety Health <br />Administration. The operator provided a Noise Assessment that was completed by an <br />engineering company to adequately quantify the potential output levels, while providing <br />mitigation that would meet the needed requirements. This assessment is provided in Appendix <br />2. It is not anticipated that any permitting will be required for this activity. <br />Air quality will also be monitored in accordance with the Colorado Department of Public <br />Health and Environment regulations. A permit is anticipated to be required for operation of the <br />generator associated with this operation. In addition, a Fugitive Dust Control Plan will be <br />submitted to the State of Colorado. Dust levels will be also be periodically collected by the <br />Mine Safety Health Administration. <br />Mining Operation <br />Material that is excavated would be placed on a grizzly which would separate out the larger <br />material (i.e. >4inch) and the smaller material would be captured on a belt feeder that would <br />run the material over a plate feeder (which evens flow of material) and into a trommel /wash <br />plant. This equipment uses water that is a combination of recycled and other purchased (or <br />possibly well in the future) water to enable washing and separation of finer materials. These <br />finer materials would drop out of the bottom of the trommel and then run through a sluice box <br />5 <br />
