(Page 2) MINE ID # OR PROSPECTING ID #: M-7974-not INSPECTION DATE: 5-~a-nt OBSERVATIONS INSPECTOR'S INITIALS: ~iL Completed an inspection of this operation as part of a Mined Land Reclamation Board directive to inspect every mine in the state at least once every four years. This is a 42 acre 112 Regular permit located about Y: mile west of Highway 85 on West Titan Road then about 1 mile south on North Moore Road. A mine ID sign has been placed at the entrance of the permit area pursuant to Rule 3.1.12(1). The permit boundary has been adequately delineated, primarily with barbed wire fences. Mining operations have occurred in the east 35 acres of the permit. The west 7 acres contain a weigh scale and is being used to store construction equipment (as approved in the permit). Mining occurs intermittently primarily in the southern portion of the permit. Mining is progressing to the south. Highwalls are near vertical and about 40 feet high. According to the operator, the highwalls will be sloped to a 3:1 gradient by backfilling and grading washed fines. The material will be dumped over the edge of the highwall, if possible, or dumped at the toe of the highwall. Grading costs are higher if the material has to be graded uphill. Currently, the flat pit floor is being used to store and process concrete and asphalt waste. Stockpiles are located throughout the excavated pit. This activity has not been approved. The operator was required to submit a technical revision in 7996 to incorporate the activity aker the site was inspected by a DMG inspector. The T.R. was supposed to be submitted by September 16, 1996. However, a technical revision was never received by the Division. The operator will be required to submit a technical revision (and the appropriate fee) to address this problem. The importation of material that has been generated outside this permit has not been approved so the operator must submit sufficient information describing how this material will be handled (processed), how much will remain onsite, where the material will be stored, how the material will be used for reclamation (if it will be used for reclamation), whether the material is inert or not, and how much more bond will be needed to reclaim the site. This is noted as a problem on page 3 of this report. The T.R. must be submitted to the Division by the corrective action due date. Construction equipment is allowed to be stored in the west 7 acres of the permit. However, construction equipment is being stored in portions of the east 35 acres. The operator cannot reclaim these lands to the approved post-mining land use (rangeland) if the equipment is not removed. This is noted as a problem on page 3. The operator must remove the construction equipment from areas outside the west permit area by the corrective action due date. Currently, crushed asphalt waste is processed through a wash plant. Water from Plum Creek is pumped into a large pit where it is then pumped to the wash plant. The return flow, and fines, are pumped to a second pit. The fines are cleaned out of the pit frequently and placed near the south highwall. There are no water rights issues since the SEO informed the operator that water was available from Plum Creek during times of "no call". After the product is stockpiled, the excess water percolates out of the pile, runs across the pit floor, flows through a small dam comprised of aggregate material and renters the Plum Creek flow regime. It is not known whether this activity needs a discharge permit so a copy of this report will be sent to WQCD for their review. However, it will be noted as a problem on page 3. The operator will be required to obtain an NPDES permit, if necessary. 1 & E Contact Address NAME: Bill Lawrence OPERATOR: Lawrence Construction Comoanv STREET: 9002 North Moore Road CITY/STATE2IP: Littleton CO 80125 Cerfilfiedl mcu0 ~ ~ o0o I b1 ~ o000 o boa James Stevens cc: ^ CE ^ BL ^ FS ^ HW ^ HMWMD (CH) ^ SE X WQCD (CH} -' l85 ^ OTHER
