<br /> <br />MINE ID # OR PROSPECTING ID # M-82-147 <br />INSPECTION DATE_December 9, 1997 <br /> <br />INSPECTOR'S INITIALS _TAS <br />RVATIONS <br />1. A site inspection was mzide of the Nyholt/Mann Lake Pit located 4 miles southwest of <br />Brighton, Colorado, <br />2.yholt/Mann Lake Pit is permit <br />$7 in the form of a. Corporate <br />recr~gtation and water storage reservoirs. <br />3. The operator has posted .sn entrance <br />with Rule 3.1.12. <br />(Page 2) <br />ted for ~9E~5 acres with a financial warranty of <br />Surety. Th~e,,~~~d±.esignated post-mining land use is <br />~,tp'"'fsi~„~5~3,'w,~,nfd 3 J2°„~i 1 ~`5Q <br />sign and marked the permit boundary in compliance <br />4. The Nyholt/Mann Lake P_~t is active and contains approximately 46 acres of active <br />disturbance in Phases 1, 2, and 3 of the operation. All disturbance was observed to be well <br />within the permit boundary and in accordance with the mining plan. Mining will occur in 4 <br />phases and will result in tYie creation of 3 lined water storage reservoirs with a total <br />surface area of approximately 158.2 acres. An additional 45 of acres have been partially <br />reclaimed in the Phase 2 area to the extent that the pit slopes have been graded to final <br />contours and sealed with clay. Active mining was occurring in the Phase 3 area at the time <br />of inspection. The processing plant is located in the Phase 1 area. <br />5. Water is currently being pumped from the active pit disturbance in Phase 2 and discharged <br />to the Bratner Ditch under th•= terms of an NPDES Permit issued by the Colorado Department of <br />Health. <br />6. Review of the permit file does not indicate that adequate water rights for water storage <br />and evaporative loss have been attained from the Office of the State Engineer. In order to <br />clarify this concern, the Division requests that the operator provide the Division with an <br />update on the status of the water rights needed for both the mining and reclamation phases <br />of the operation and of the wziter rights already obtained. This information is necessary for <br />the calculation of a current reclamation cost, as mentioned in item 7 below. <br />7. The existing reclamation cost was last calculted in 1988 and was based on a maximum <br />disturbance of approximately 40 acres. The Division will calculate a current reclamation <br />cost, within the next 60 ds+ys, based on the existing disturbance and the terms of the <br />reclamation plan. During the inspection Mr. Pachura agreed to provide the Division with haul <br />distances and volumes of stockpiled overburden and topsoil at the site as well as volumes <br />of concrete and steel for non-portable portions of the processing plant. The Division will <br />keep the operator advised of any necessary changes to the financial warranty amount. <br />I & E Contact Address <br />NAME Julie Goet~~=emoeller <br />OPERATOR Mobile Premix Concrete.
