• Savage and Savage <br />Memorandum <br />To: Donald W. MacDonald, Coors Energy Company <br />From: Michael Savage, Savage and Savage, Inc. <br />Date: December 19, 2002 <br />Subject: Fourth Quarter 2002 Pest and Disease Inspection; Keenesburg Mine <br />File #: C-81-028 <br />On December 19, 2002 I conducted an inspection of the reclaimed and revegetated azeas <br />at the Keenesbwg Mine for evidence of plant pests or diseases that could affect the re- <br />established vegetation at the Keenesburg Mine. <br />Vegetation at the mine was in good condition given the drought conditions during the <br />2002 growing season Nearly all revegetated azeas showed growth and flowering by <br />native cool and warm season grasses, though overall stature was much reduced from <br />normal precipitation years. Few annual weeds were observed throughout the revegetated <br />azeas. All reclaimed and revegetated areas of the mine, including the 1985, 1986, 1987, <br />• 1995, 1998, 1999, 2000, and 2001 seedings, and azeas seeded to sorghum were inspected <br />by pedestrian and vehicle means. The sediment pond bottom and sides were also <br />inspected for arty potential weedy invasive species. No disease conditions at any of the <br />reclaimed and revegetated areas were observed: Nor were any plant pests, which had <br />affected the growth of the vegetation during the past growing season, found. No bare <br />areas, areas evidencing wind or water erosion, or azeas which experienced any infestation <br />or blight were identified during the inspection. <br />C: Keenesburg Pest and Disease Inspection File <br />r1 <br />L_J <br />AHR-2002 _qq_ <br />
