Farrell Mined Land Reclamation Division 423 Centennial Building 1313 Sherman Street Denver, Colorado 80203 iii iiiiiiiiuiii-ii ~~/~~~~~ JUN 211965 MINED LAND RECLAMATION DIVISION RE: Technical Revisions Fremont Paving and Redi-Mix File, McKenzie Pit, M. L. R.D. File No. M-80-224 Dear Ms. Farrell: In response to your letter of Inspection and Inspection Report dated May 8-9, 1985, a technical revision is hereby being submitted.which addresses allof the items pertaining to this pit. There will be one difference frmn the approved pit permit. After the operator mines Area "A", Phase 1 (5 acres), which has been completed in 1985 according to the mining plan, the next mining area will be Area "C", Phase 3, instead of the previously indicated Area "B", Phase 2. Phase 3 contains 11 acres and will start in 1985 and be completed in 1990. The operator will start at the east face and proceed north and west, with 2. 5 acres (approximately) being mined each year. After this area is mined, the operator then plans to mine area "B", Phase 2, which contains 5 acres and will start in 1990 and be completed in 1992-1993, and will start at the north side of Phase 2, with approximately 2 1/2 acres being mined each year. The affected area will remain the same and the mining and reclamation plan will remain the same per the approved pemit. A mining plan map (1 inch= approximately 200 ft.) is enclosed. The Colorado Mined Land Reclamation Rules and Regulations does not require a contour interval of 5 ft. , and I have furnished a map with an interval of 20 ft. , which is standard and adequate to portray the direction and rate of slope of the affected area. A drainage plan is also enclosed. In response to the recommendation that a qualified professional handle the required reports, Ifeelthatthis issue has already been addressed and qualified maps, data, and other information is hereby being submitted. I trust that the enclosed technical revisions complete the adequacy portions of this permit per your specifications, and as all timelines have been met thus far, con- sideration for possible violations by the Mined Land Reclamation Board are hereby deferred per your letter of May 8-9, 1985.
