field season. MCC also completed testing and removal of petroleum products, emulsion fluids, and other <br />chemicals and chemicals wastes from the Shop /Warehouse and Multi- Services Building using a licensed <br />waste contractor. <br />Ongoing maintenance activities included inspection and clean -out of drainage structures (as needed), and <br />focused weed control activities under our Noxious Weed Management Program. Limited rodent - control <br />activities occurred during 2011. The 2005 -2007 control efforts were effective in significantly reducing <br />the ground squirrel population, and while rodents are still observed on the property, population numbers <br />seem to have stabilized. Spot and area spraying efforts were expanded for noxious weeds in 2011 to <br />address an increase in weed occurrences due to climatic factors. Spraying was completed by Peabody <br />Environmental Staff, and Reclamation Personnel, and was supplemented by contractor weed spraying. <br />Primary targeted weed species included Russian knapweed, hoary cress (white -top), Canadian thistle, <br />hound's- tongue, and tamarisk. Selective herbicide applications utilized 2,4 -D, Tordon, Escort, Milestone, <br />Sahara, Throttle, and triclopyr (tamarisk). Spraying was conducted from June through October, and <br />covered a total of approximately 85 acres. <br />Areas treated included, but were not limited to: <br />- Roadsides (main entry road, roads on the plateau area north and west of the road leading to the <br />7 -North Angle Well, and portions of the main entry roads in both the east and west mine <br />facilities areas) <br />- Refuse Pile area <br />- No. 9 Mine Shop area <br />- Areas in and surrounding the west Mine Facilities area (i.e. Water Treatment Ponds, <br />Office /Warehouse, Bathhouse, Coal Handling Facilities, Railroad Spur, Wastewater Treatment <br />areas, and yard areas) <br />- The open meadow to the north of the reclaimed Mine No. 4 portals <br />- Recently reclaimed areas <br />- The southern portion of the reclaimed Williams Fork Strip Pit <br />- Mine substations (Glystar) <br />- Peabody lands to the west of the Yampa River <br />Limited tamarisk control efforts (spot treatment — not shown on map) focused on isolated occurrences <br />along the main access road and in areas adjacent to the Williams Fork River. MCC contracted with a <br />local rancher (John Raftopoulis) to hay several areas including the Williams Fork bottom, the plateau area <br />south of the 7 -North Angle Well, and the hillside to the east and south of the old highway. <br />Attached are copies of the standard form (CDRMS) Annual Reclamation Report for 2011, and 2011 <br />Annual Reclamation Report Map.
