I was not accompanied by an operator contact,but checked in at the mine office and spoke to Dennis <br /> Jones, SCC Hydrologist,prior to the inspection. Weather was cloudy,with intermittent rain showers that began <br /> shortly prior to the inspection. The inspection focus was on grading and drainage repairs recently implemented in <br /> the vicinity of the reclaimed solid waste disposal site(reclaimed in 2008), in the upper SIIPM-10 watershed. I <br /> also drove Road El to the South Road junction, drove the length of the South Road, and inspected Sediment Ponds <br /> 004, 008,and adjacent areas. The permit for the new Sage Creek permit area was recently approved by DRMS. <br /> The Seneca II permit area now overlaps with much of the new Sage Creek permit area. Permit Revision No.2 <br /> (PR-2), currently under review,would reduce the Seneca II permit area by 3011.9 acres. The much smaller <br /> Seneca II permit would be limited to the Pond 008 watershed in the East Wadge area,upon approval of PR-2. The <br /> remainder of the current Seneca II permit area has been included in the Sage Creek permit area. <br /> BACKFILL and GRADING—Rule 4.14 <br /> Contemporaneous Reclamation 4.14.1; Approximate Original Contour 4.14.2; Highwall Elimination 4.14.1(2)(f); <br /> Steep Slopes 4.14.2, 4.27;Handling of Acid and Toxic Materials 4.14.3; Stabilization of Rills and Gullies 4.14.6: <br /> The eroded segment of TRM lined channel at the upper end of SIIPM-10 (lower end of the regraded solid waste <br /> disposal site)had been recently graded and prepared for installation of replacement TRM liner. A short tributary <br /> gully that enters PM-10 in the close vicinity had also been graded to a channel configuration, and prepared for <br /> TRM installation. These channel segments will need to be seeded,and TRM will need to be installed. The <br /> operator indicated that the work would be completed shortly. <br /> Number of Partial Inspection this Fiscal Year: 1 <br /> Number of Complete Inspections this Fiscal Year: 0 <br /> Page 2 of 7 <br />
