• Savage and Savage Memorandum To: Donald W. MacDonald, Coors Energy Company From: Michael Savage, Savage and Savage, Inc. Date: March 9, 2009 Subject: First Quarter 2009 Pest and Disease Inspection; Keenesburg Mine File #: C-1981-028 On March 4, 2009, Edith and I conducted an inspection of the reclaimed and revegetated areas, as well as adjacent operational areas at the Keenesburg Mine for evidence of plant pests, noxious weeds, and plant diseases that could affect the re-established vegetation at the Keenesburg Mine. Conditions at the mine site are very dry due to a lack of winter precitpitation. This winter season has also been windy, and conditions during the inspection were representative, with gusts to 30 miles per hour. All reclaimed and revegetated areas of the mine, including the 1985, 1986, 1987, 1995, • 1998 interseedings, 1999, 2000, 2002, and 2003 seedings were inspected by pedestrian and vehicle means. The dugout area, the small cottonwood grove, the sediment pond bottom and embankments, topsand piles, B Pit, and long-term overburden storage area were also inspected for any potential problem areas. Areas around the fenced oil and gas drill pads and roads were also inspected for potential encroachment of weeds or plant pests from those enclosures. We did not identify any disease conditions at any of the reclaimed and revegetated areas or within the mine site. Nor did we identify any plant pests which had affected the growth of the vegetation during the past growing season. No areas which experienced any infestation or blight were found during the inspection. No patches of noxious weed species were observed, nor were any areas observed where weeds, plant pests, or disease showed a deleterious effect to the live vegetation.
