• (Page 3) • <br />MINE ID ~ OR PROSPECTING ID ~ M-82-015 <br />INSPECTION DATE 7/31/95 INSPECTOR'S INITIALS ACS <br />approved revegetation plan for this site consists of seeding with the following mixture of <br />grasses: <br />Species Variety Rate/Broadcast (in pounds <br />per acre) <br />Western Wheatgrase Arriba 12.8 PLS <br />Yellow Sweet Clover 2.8 PLS <br />Smooth Brome 10.4 PLS <br />The approved plan also calls for planting of the following trees and ehrube: <br />Trees <br />Siberian Elm <br />Plains Cottonwood <br />Hackberry <br />Boxelder <br />Russian Olive <br />Shrubs <br />Skunkbrueh Sumac <br />American Plum <br />Siberian Peaehrub <br />Chokecherry <br />Hanson Hedgeroee <br />western Sandcherry <br />Willow <br />The trees are to be planted on 20-30 foot spacings and the ehrube to be clumped 6-8 feet <br />apart with 6-10 of the same species per clump, and clumps spaced 50 to 75 feet apart. This <br />works out to about 64 trees per acre, for a total (minimum) of 5952 trees to be planted, and <br />128 shrubs per acre for a total (minimum) of 11,904 ehrube to be planted. The Division <br />recommends that Russian Olive be eliminated from the list of trees to be planted, ae these <br />trees have been found to be undesirable from a wildlife habitat standpoint. The Division <br />further recommends that 2 tone per acre hay or straw mulch be spread over seeded areas and <br />crimped into the soil. Since it is the Division's view that acceptable grass establishment <br />will require that the site be mulched, a coat for mulch application will be included in the <br />reclamation coat estimate. <br />In the worst case, from a reclamation coat standpoint, the de-watering pump would have been <br />removed, and the pits flooded. In this situation, at least partial de-watering would be <br />required to facilitate grading and topsoil replacement. With 134 acres of water surface, and <br />a 15 foot average water depth (from approved Reclamation Plan Map), there would be a total <br />of 655 million gallons of water in the lakes. Dewatering costa from 1994 CDOT Coet Data are <br />$230.00 per million gallons. If 25 percent of the water in the lakes had to be pumped out <br />to facilitate reclamation, the resulting cost would be $38,000.00. <br />In general, this site ie found to be in compliance with the approved mining and reclamation <br />plane. Problems noted during this inspection that require corrective actions to be completed <br />by specific dates are listed on the last page of this report. The operator should complete <br />reclamation of the east (97 acre) pit to the extent practicable, taking into consideration <br />the need to load out remaining stockpiled product. <br />cc: Carl Mount, DMG <br />Dick Wolfe <br />Divia ion of Water Resources <br />1313 Sherman St. Room 818 <br />Denver, CO 80203 <br />I & E Contact Address <br /> ^ CE <br />NAME Bob Sieoriet ^ BL <br />OPERATOR Sieoriet Construction Comoanv ^ FS <br />STREET 6999 North York Street ^ HW <br />CITY/STATE/ZIP Denver, CO 80229 ^ HMWMD (CH) <br /> ^ SE <br /> ^ WQCD (CH) <br /> ^ OTHER <br />
