MWCA, Inc. <br />Date: February 8, 2011 <br />Reference: Permit # M-1977-227 <br />Subject: Mesita Hill Pit Annual Report for 2010 <br />The only activity conducted at Mesita Hill in 2010 was monitoring of the <br />success of vegetation growth from the revegetation conducted in November <br />2008 after completion of the 2008 reclamation activities. As of the end of <br />2008, the site had been contoured, smaller pits filled and larger pits <br />contoured to allow use for livestock grazing. The available growth material <br />was spread out as much as possible. Recontouring was also completed <br />outside of the permit boundary, if possible without disturbing mature <br />vegetation. The site was visited once on May 30, 2010 to monitor <br />vegetation success. See attached Bamberg Ecological report dated June 4, <br />2010. This report noted some basal leaf sprouting of Canada thistle. This <br />area, located near the concrete pad, was subsequently sprayed with 2-41) <br />on August 3, 2010. <br />MWCA personnel and contractors were onsite during the DRMS inspection on <br />October 7, 2008. As the inspector noted, there are several Technical <br />Revisions required in order to revise the reclamation plan. These include a <br />weed control plan and a final grading plan. The technical revision request <br />is currently being completed. See attached DRMS Inspection Report dated <br />October 7, 08. <br />20 <br />Paul L.
