• Savage and Savage <br />Memorandum <br />To: Donald W. MacDonald, Coors Energy Company <br />From: Michael Savage, Savage and Savage, Inc. <br />Date: May 12, 2003 <br />Subject: Second Quarter 2003 Pest and Disease Inspection; Keenesburg Mine <br />File #: C-81-028 <br />On May 1, 2003 I conducted an inspection of the reclanned and revegetated areas at the <br />Keenesburg Mine for evidence of plant pests or diseases that could affect the re- <br />established vegetation at the Keenesburg Mine. <br />All reclaimed and revegetated areas of the min, including the 1985, 1986, 1987, 1995, <br />1998 interseedings, 1999, 2000, and 2002 seediags were inspected by pedestrian and <br />vehicle means. The dugout area, the small cottonwood grove, and the B Pit areas were <br />also inspected for any poternial weedy invasive species. I did not identify any disease <br />conditions at any of the reclaimed and revegetated areas 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 />The mine site has received significantly more precipitation during the winter and early <br />spring than during the same period last year. As a result, early growth of cool season <br />perennial grasses was observed throughout the mine site. Danny Kipp and I identified <br />several small areas (within Areas 6, 7, and 10) where light burns could be employed to <br />m;nim;~~ cheatgrass regeneration later this spring, given suitable bum conditions. <br />In the spirit of extending Executive Order D 002 03 (Eradication of Tamarisk on State <br />Lands) to the private lands at the mine, Danny will remove the few tamarisk shrubs on the <br />mine site this spring through mechanical means. <br />C: Keenesburg Pest and Disease Inspection File <br />Damry Kipp, Keenesburg Mine <br /> <br />AHR-2003 -46- <br />
