• (Page 2) • t MINE ID # OR PROSPECTING ID # M-77-443 INSPECTION DATE 12/16/99 INSPECTOR'S INITIALS TAS OBSERVATIONS 1. A site inspection was made of the Moon Pit as part of the Division's 9-Year Inspection Program. Present during the inspection was Mr. Pat Weber of Hardrock Sand and Gravel. The pit is located in Moffat County 17 miles west of Craig along County Road `. 2. The Moon Pit is permitted for a total of 5 acres. The operator has posted a financial warranty of $2,500 in the form of a Certificate of Deposit. The post-mining land use is rangeland/grazing. Disturbed slopes will be graded to no steeper than 3H:1'/, topsoiled, and seeded with a rangeland mix. 3. Virtually all of the 4.99 acres shown on the mine plan map are disturbed. All disturbance appears to be within the permit boundary. Disturbances include pit highwalls, overburden and topsoil stockpiles, and product stockpiles in the floor of the pit. Reclamation [asks to be completed include the following: 1)reduce approximately 1900 linear feet of pit wall averaging 14' high from a 1:1 to 3:1 slope, 2) finish grading of approximately 1.0 acre-feet of pit floor, 3) backfill and grade approximately 8000 cubic yards of over~.~urden stockpiled around the periphery of the pit, 4) replace approximately 4000 cubic yards of topsoil stockpiled around the periphery of the pit, and 5) revegetate approximately 5 acres. The Division has calculated a total cost of $9,800 to complete these tasks. (See attached COSCS). 4. Since the estimated reclamation liability at the site is $9,800, the existing financial warranty is not adequate to complete the reclamation plan. The Division considers this matter to be a problem that will require corrective measures. The Division requests that the operator submit either a replacement warranty of $9,800 or a supplemental warranty of $7,300 within 60 days. As an alternative, the operator may perform reclamation aeasures to reduce the current liability to an amount equal to or less than $2,500. If this alternative is chosen, the operator must provide photographs and a written description of reclamation tasks completed. Please see page 4 for details. Attached are warranty forms for your use. 5. There was no entrance sign present at the time of inspection. Mr. Heber noted it is likely that cattle grazing in the area have knocked down the sign noted during previous inspections. This concern is noted as a problem and the operator was directed to replace the sign. See page 4 for details. The permit boundary markers were still iri place. 6. Mr. Weber expressed an interest in mining an additional 5 acres to tt~e south. The mine plan map submitted in 1992 shows a proposed permit area of 4.98 acres immediately to the south. The Construction Material Rules & Regulations allow for disturba~ices of up to 9.99 acres for Limited Impact 110c Permits. Therefore, in order to disturb +idditional acreage under the terms of Permit No. M-90-134, the operator will need to submit -sn application for a permit amendment with $575 application fee. The Division estimates Che reclamation cost for the additional 4.98 acres to be $10,500 assuming the same mining and reclamation plan is used. Attached are application and warranty forms as well as reclamation cost estimate.
