There is a <br />Spill Prevention Control and Countermeasure Plan in place. There <br />have been no spills and "no discharge" has been reported to the <br />Colorado Department of Health and the EPA, on a quarterly basis <br />since the mine opened. There are no buildings on site and there no <br />materials stored on site. One small portable coal crusher remains <br />on site but will be removed in the near future. There were 7 acres <br />disturbed by the operation. <br />As indicated on the map the facilities include diversion <br />ditches and a sediment pond. A small area exemption application is <br />in process to include any disturbed area runoff that may not be <br />received by the current sediment pond. The exempt area is <br />indicated on the map as well as the control structures in place at <br />the mine. Once the Technical Revision Application for the small <br />area exemption is approved, all of the disturbed area runoff at the <br />mine will flow through a control structure, except the outslope of <br />the sediment pond. <br />There are no operations, processing activities, stored <br />chemicals, mine drainages, tailings ponds, significant dust or <br />particulate generating activities, any kind of waste disposal, or <br />stockpiles of any kind that may be pollutant sources. <br />9901 South Windermere Street, Littleton, Colorado H0120 <br />Telephone: (303) 795-5130 Fax: (303) 795-3299 <br />
