1� WAGNIM RECEIVED ROCK LLC. OCT 14 2016 Spec aggregates 1850 E. I". street, Craig, CO 81625 DIVISION OF RECLAMATION MINING AND SAFEfY Phone & Fax (970) 824-2709 WagnerCorpColo@aol.com 2016' Inspection of Wagner Rock Pit M1999-018 Financial Warrantee Increase Objection v 10-05-2016 Upon further review of DRM&S estimates and calculations of backfill quantities, it appears that the division has a different view of post mined land use and the reclamation plan of the pit. Since there has been no change in regulation affecting our reclamation plan, we conclude that the existing mining plan remains in affect. Our reclamation of the pit will include grading the floor area leaving aggregate exposed for the storage of hay. The North slope will be mined leaving the pit open and exposed to the north. A small safety berm will be shaped with a 3 to 1 slope and revegetated. Quantities for this berm are in place at this time. All other side slopes will be pulled down to a 2 to 1 slope and revegetated with top-soil that is piled on the South side of the pit. Adequate quantities currently exist for this effort. Remaining stockpiled material currently stored outside of the excavation are marketable aggregates and will be sold. In conclusion, the fill as estimated by the division far exceeds the required need for the current reclamation plan, the use of a CAT D-9 exceeds the mechanical needs for reclamation, a CAT D-6T is more than enough at less than 40 hours. There is no expectation, according to the mining plan to backfill the pit. The scale house will not be demolished! It is a mobile office trailer and the scales are portable scales requiring little removal effort. No ripping is necessary of stockpile areas as all material is loose and uncompacted. A CAT D-6T is capable of transferring the material. At this time the disturbance does not exceed 4 acres. Revegitation and topsoiling unit cost should be adjusted down. T
