Minor Revision No. 265 <br />August 31, 1999 <br />Page 2 <br /> casing, and open <br /> hole <br />GGG 195 6-in. steel casing, Existing road 50' x 50' <br /> 4-in. PVC <br /> casing, and open <br /> hole <br />A culvert will be placed at the East Sylvester Gulch drill road to allow the drill rig to access FFF <br />and GGG. A stream crossing will also be required to access EEE. There is currently no flow in <br />the upper reaches of the East Fork of Sylvester Gulch. Topsoil will be windrowed along the road <br />to be constructed to access EEE, as has been done with other drill roads. Cut and fill to establish <br />the road to EEE will be kept to a minimum. Silt fence will be placed below the road, and <br />drainage will be established on the road by using road ditches and water bazs. <br />It is expected that water may be used for this drilling project. MCC plans to utilize our water <br />right in Sylvester Gulch and either pump or haul the needed water to the drill site. <br />Once the drilling has been completed, both of the culverts will be removed and low water <br />crossings established at both stream crossings to facilitate access for future monitoring. Once <br />monitoring is completed, MCC will seal the holes according to Rule 4.07.3 depending on <br />conditions encountered, and the casing will be cut down below grade. The road created to access <br />EEE will be backfilled and the windrowed topsoil replaced. The site will be hand seeded with <br />MCC's approved permanent seed mix. <br />MCC plans to begin the earthwork construction on September 13'". Drilling is expected to begin <br />later that week. The entire project should be completed by October 8ih. <br />Please call if you have any questions. <br />Clvistine E.
