Colors correspond to the year in which the area was seeded (per the 2008 <br />Annual Reclamation Report). <br />Surface mining commenced at the eastern side of the ridge between Jeff Canyon and the <br />Purgatoire River. Mining progressed to the west, with development of a highwall and fill <br />construction in the small side drainages. Fills 7, 8, and 9 were constructed as a result of mining <br />operations. Overburden material was moved using a combination of dozers, trucks and loaders. <br />Sediment control structures were constructed in advance of the disturbance in each small, <br />ephemeral watershed. Ponds 5, 6, 7, 8, 9, and 9A were constructed and still exist at the time of <br />RN -04. Pond l0A was released under SL -02 as part of the coal loadout. Overburden material <br />was regraded to a modified ridgeline prior to re-application of subsoil and/or topsoil material. <br />Surface mine facilities were portable and were located at two areas: the office area and the <br />service area (Map 2.05.3-2, 5 -Year Mine Plan). Two rail cars for storage and an office trailer <br />were located at the Office Area. The office trailer was removed shortly after the cessation of <br />mining activities. The rail cars were requested to remain by the landowner and were released <br />under SL -02 in July 2008. During the brief period of operation, coal was transported from the <br />pit area by haul trucks and stockpiled at the coal loadout at the mouth of Lorencito Canyon. <br />
