ing of water from the pit. The CDPHE has revised the Waste Management Contingency Plan which <br />covers all aspects of the monitoring of soil materials and water as related to the mining operation. <br />This revised plan, to account for the revised mining operation plan of May 2003, is also included in <br />Appendix D. The Plan calls for detailed testing procedures in addition to specific procedures if any <br />contamination is found. If any solid waste in soil is encountered during testing or operation, the fol- <br />lowing procedures will be implemented: <br />1. All excavation activities will cease in the azea of the discovered waste. <br />2. Site personnel will notify Elam Construction, Ines. Health and Safety Officer and Elam's certi- <br />fied Hazardous Materials Manager (HMM). CDPHE Hazardous Waste Division, DMG and Mesa <br />County Health Department will be immediately contacted. <br />3. Upon investigation of the solid waste, vazious options will be considered such as: a) Cover the <br />solid waste and continue extraction activities outside of the azea or b) Remove and dispose of the <br />waste at an approved solid waste land fill site. <br />If water contamination is encountered and water tested at the sediment pond could discharge above <br />levels of contamination prescribed in the Combined Process Water and Storm Water Discharge Per- <br />mit aswell as the Waste Management Contingency Plan, pumping from the pit will stop and treat- <br />ment options for the water will be discussed with input from the agencies listed above. <br />Since any free product or other petroleum contamination produces a sheen on the water surface, the <br />monitoring of water in the operation can now easily distinguish between contamination from the <br />plume to the north of the permit area and any contamination from equipment operation in the pit <br />itself. If any contamination enters the site from the plume to the north, it will be seen in the <br />trenches. If fuel spills etc. originate from the mining operation, it will be seen in the water pumped <br />to the sediment pond. If the trenches show a sheen while the sediment pond does not, this indicates <br />that contamination is migrating from the north into the trench. In this case, all parties will be noti- <br />fied and an appropriate course of action will be taken, although this case is highly unlikely. If a <br />sheen is seen in the sediment pond, an inspection of the pit pumping area and trenches will be made <br />to see if any leak from mining equipment is the cause. The inspection log will note such an occur- <br />Gilsonite Fit 9/03 23 <br />
