• Savage and Savage <br />Memorandum <br />To: Donald W. MacDonald, Coors Energy Company <br />From: Michael Savage, Savage and Savage, Inc. <br />Date: May 18, 2009 <br />Subject: Second Quarter 2009 Pest and Disease Inspection; Keenesburg Mine <br />File #: C-81-028 <br />On May 14, 2009, as an adjunct to the Phase III bond release inspection, I conducted an <br />inspection of the operational, reclaimed, and revegetated areas at the Keenesburg Mine <br />for evidence of plant pests, noxious weeds, and plant diseases that could affect the re- <br />established vegetation at the Keenesburg Mine. April precipitation from one significant <br />event has yielded significant growth in the cool season graminoid and forb components at <br />the mine. Mountain brome, Indian ricegrass, western wheatgrass, cheatgrass, and ragweed <br />showed early season growth. <br />• The 1985, 1986, 1987, 1995, and 1997 reclamation areas were inspected by pedestrian <br />and vehicle means. Additionally, surrounding areas; including the small cottonwood <br />grove, topsand piles, B Pit and adjacent area, the periphery of the long-term overburden <br />storage area, boundaries of the fenced oil and gas pads and roads, and several areas <br />outside the former mine disturbance area were also inspected for any potential problems. <br />We did not identify any disease conditions at any of the operational, reclaimed, or <br />revegetated areas of the mine site. We did not identify any plant pests which had affected <br />the growth of the vegetation during the past growing season or over the winter. No areas <br />which experienced any infestation or blight were found during the inspection. No patches <br />of noxious weed species were observed, nor were any areas observed where weeds, plant <br />pests, or disease showed a deleterious effect to the live vegetation. <br />C: Keenesburg Pest and Disease Inspection File <br />Danny Kipp, Keenesburg Mine <br />• <br />AHR-2009 -29-
