• Savage and Savage <br />Memorandum <br />To: Donald W. MacDonald, Coors Energy Company <br />From: Michael Savage, Savage and Savage, Inc. <br />Date: November 23, 2004 <br />Subject: Fourtb Quarter 2004 Pest and Disease Inspection; Keenesburg Mine <br />File#: C-81-028 <br />On November 23, 2004, in conjunction with the Phase I bond release inspection, I <br />conducted an inspection of the reclaimed and revegetated azeas at the Keenesburg Mine <br />for evidence of plant pests or diseases that could affect the re-established vegetation at the <br />Keenesburg Mine in conjunction with the Phase I bond release inspection. <br />Reclaimed and revegetated azeas of the mine, including the 1985, 1986, 1987, 1995, 1998 <br />interseedings, 1999, 2000, 2002, and 2003 seedings were inspected by pedestrian and <br />vehicle means. The dugout azea, the small cottonwood grove, and the B Pit areas were <br />• also inspected for any potential weedy invasive species. I did not identify any disease <br />conditions at any of the reclaimed and revegetated azeas or within the mine site. Nor did I <br />identify any plant pests which had affected the growth of the vegetation during the past <br />growing season. No areas which experienced any infestation or blight were found during <br />the inspection. <br />Weed control activities at the mine this yeaz have included spraying and mowing. <br />Spraying occurred in the spring when weeds were actively growing. Mowing activities <br />took place in November 2004 in Areas 9, 14, 15, and 29, effectively reduced standing <br />biomass of annuals and thatch buildup. <br />C: Keenesburg Pest and Disease Inspection File <br />Danny Kipp, Keenesburg Mine <br /> <br />Page 45 <br />
