Mr. Tom Schreiner Division of Reclamation, Mining, and Safety May 31, 2007 Page 2 of 4 for the site, approved by the Office, and a reclamation plan was formulated. As stated in Exhibit E of the Reclamation Permit Application, the final reclamation plan for this portion of the site was to return the disturbed ground to pastureland and to match the reclaimed grade of the property to the pre-existing grade.- Consistent with Exhibit E, backfilling of the mined pit and grading activities. were concurrent with mining operations. As listed below, reclamation' of the. site has complied with additional subsections of the Reclamation Performance Standards. 3.1.5 Materials Handling To meet requirements, the following activities were performed. • Grading created .a final -topography appropriate for the permitted final land use, pastureland. •: Backfilling was performed with adequate compaction for stability. No structures aze ' planned for the site, so compaction testing was not necessary. • No mining highwalls were left on the site and all slopes were graded to control potential _ erosion and siltation. •. Grading of all slopes was,done as mining progressed. • No refuse, acid-forming, or toxic producing materials were mined or produced on the site. • No drill or auger holes were part of.the mining operations and no adits or shafts were created. • No._significant slopes were left on the site: Slopes aze consistent with the pre-existing topography and appropriate for use as pastureland. ' • The reclamation choice. for pastureland may require that the area be plowed, planted and mowed. The azea is graded so farm machinery can traverse. the, area when needed. s Structural fill was not used to backfill the excavated pit. • Material that could potentially cause unauthorized releases of pollutants to the surface drainage system was not mined or disposed of within the affected azea. • No unauthorized release of pollutants to groundwater occurred from materials mined or = handled within the perniit azea. All baclcfilling and grading was done as mining progressed. Final grading was, completed in ilie summer of 2005 after the completion of mining activities. Revegetation at the site was performed in Fall 2005. 3.1.6 Water -General Requirements Disturbances to the prevailing hydrologic balance of the affected land and surrounding azea were minimized. • The operator has complied with applicable Colorado water laws and regulations governing injury to existing water rights.
