The <br />inspection was conducted to determine the adequacy of the bond held by the operator. The site is located <br />on the Rocky Flats Piedmont, about'/, mile east of State Highway 93, about 12 miles south of Boulder. The mine <br />is a sand and gravel operations utilizing standard excavating and haulage methods. Multiple crushing and <br />grinding circuits produce aggregate of various sizes. No blasting is necessary. <br />Observations: <br />' No erosion problems observed. <br />A minor amount of water was standing in the pit floor, derived from recent precipitation. <br />No ground-water inflow to the pit occurs, and from our vantage pit on the rim, no highwall seeps were seen. <br />the mine experiences frequent temporary shut-downs due to high winds. <br />The mine has a large stockpile consisting of an estimated 400,000 cubic yards of material. <br />The operator has inherited a few problems from the previous owner. Most notable are a weed issue and pit <br />benches/highwalis that are not OSHA/MSHA compliant. The benches need to be widened and the highwalls <br />need to be shortened. Operator indicated this will be addressed soon. <br />There is a minor weed problem. The Division inquired about a weed control plan, and the operator said that it <br />was in place and administered by a crew that rotated among all of the operator's various facilities. <br />The reclamation liability was reviewed as required during a permit transfer and Succession of Operator. The <br />existing Financial Warranty is $89,000. DRMS calculations indicate that backfilling the reclaiming the stockpile <br />would cost considerably more than is available in the current financial warranty. Since the original Financial <br />Warranty appears to have contained minimal provisions for backfilling stockpiled material, the newly <br />calculated backfilling cost is in addition to the existing Financial Warranty amount of $89,000. Since it has been <br />over four years since the bond was prepared, the entire site was re-calculated resulting in a new financial <br />warranty amoun#-of $550,93T,-wifha-balance due of.$461..431..---- --- ---- --- - - - ----_-- <br />In accordance with Rule 4,2.1 ~2~, the Permittee shall post the additional Financial Warranty of $461,931 within 60 <br />days from the date of posting of this inspection report. This is being cited as a problem on page 3 of this <br />inspection report along with the corrective action dotes. <br />18.
