• (Page 2) • MINE ID # OR PROSPECTING ID # M-78-352 INSPECTION DATE 7-29-96 INSPECTOR'S INITIALS GSC OBSERVATIONS This was a monitoring inspection conducted with Mr. Claude Gerard of Roaring Fork Resources. The permittee is Nottingham Sand & Gravel Co. and the operation is mined by Roaring Fork Resources. The permit totals 51.6 acres. An entrance sign is in place and Mr. Gerard pointed out the permit boundaries which are all fenced. This is a dry operation situated on a terrace south of the Eagle River. The mining plan includes concrete and asphalt batch plants, however, there is no asphalt plant currently on site. Old asphalt is stockpiled for use in recycling in the western side of the pit. The concrete batch facility and a wash plant are located near the central portion of the permit. The average highwall depth is about 22. ' Portions of the southern highwall near the western end of the permit have been graded to 2: 1 and reseeded. This is the approved gradient in the reclamation plan. The permit was amended in 1984 and the reclamation plan altered to include the replacement of 12" of wash plant fines and 4" of topsoil as growth medium during reclamation. There appears to be sufficient material on site to accomplish this. The wash plant is described in the permit file as a no discharge facility, however, the settling pond is discharging into the Stremme and Gates Ditch just north of the facility area. Mr. Gerard thought that the operator had applied for and received a discharge permit for this activity from the Colorado Dept. of Public Health and Environment (CDPHE) . If the operator has not been in contact with the CDPHE, this should be done to determine if a discharge permit is required. A 10,000 gallon steel fuel tank is located by the crusher and a 2,000 gallon fuel tank by the wash plant. These do not have lined spill containment. Another fuel tank near the scale house is bermed and lined however, the lining and berming is in disrepair. The tanks need to be adequately bermed and lined. (See Problem PS-1) There is some refuse in the pit area including miscellaneous wood and metal scrap. As a reminder, Rule 3.1.5(5) requires the operator to handle and dispose all refuse in a manner that will control unsightliness and protect the drainage system from pollution. Mr. Gerard stated that the operator is accumulating scrap and refuse throughout the site for removal around November, 1996. The current bond amount for this permit is $38,000.00 which is sufficient for the operation. No other problems were identified.
