Lorencito Canyon Mine (C-1996-084) <br />mouth of Jeff Canyon. As a result of an industrial land use bond release (SL -02), all haul roads, access <br />roads, the coal loadout, and the office area have been fully bond released. <br />Surface mining commenced at the eastern side of the ridge between Jeff Canyon and the Purgatoire <br />River. Mining progressed to the west, with development of a highwall and fill construction in the <br />small side drainages. Fills 7, 8, and 9 were constructed as a result of mining operations. Overburden <br />material was moved using a combination of dozers, trucks, and loaders. Overburden material was <br />regraded to a modified ridgeline prior to re-application of subsoil and/or topsoil material. <br />The following production rates can be found in Division records: <br />• In the year 2001, the Lorencito Canyon mine produced 13,098 tons of coal. <br />• In the year 2002, the Lorencito Canyon mine produced 154,824 tons of coal. <br />As previously noted, these were the only years of production at Lorencito Canyon. <br />During the brief period of operation, coal was transported from the pit area by haul trucks and <br />stockpiled at the coal loadout at the mouth of Lorencito Canyon. Coal was then loaded onto a 15 -car <br />shuttle train and railed to the New Elk Mine site (Permit No. C-1981-012) located approximately eight <br />miles to the west. Coal was unloaded and stored at New Elk in existing silos for subsequent loading <br />onto unit trains for transportation to market. There was no coal processing waste material produced <br />on site. <br />The surface mine was reclaimed as mining activities were completed. Reclamation activities were <br />completed in approximately five months in 2003 and 2004 and included salvaging and removal of <br />structures, backfilling and grading, topsoiling, and seeding. <br />The revegetation plan has three main objectives. The first is to assist in controlling excessive erosion <br />and sedimentation. The second is to establish a vegetative cover that is ecologically comparable to <br />the native, pre -mine community. The final objective is to restore wildlife, grazing, watershed, and <br />aesthetic values to meet the post -mining land use. <br />NECC has seeded the mine site disturbed areas with both native and introduced plant species. The <br />seed mix includes a mixture of seasonally adapted species along with introduced species that are <br />both desirable and have a good chance of success. <br />Section II - Revisions to the Permit <br />Since the last permit renewal (RN -03, approved on March 21, 2014) one technical revision has been <br />approved. TR -18, a revision of the permit boundary, was approved on November 21, 2014 and issued <br />on December 6, 2014. <br />Page 8 of 10 <br />
