DISPOSAL ACTIVITIES Ash Disposal During the calendar year 2002, a total of 41,492 tons of mixed fly and bottom ash were transported to and disposed of at the Keenesburg Mine site. Since A-Pit reclamation is complete, the entire 41,492 tons of ash was placed in South B-Pit. This brings the total B-Pit ash volume to 315,835 tons (5,667 tons in North B-Pit and 310,168 tons in South B-Pit). The total amount of ash disposed of at the Keenesburg site through the end of 2002 is 560,183 tons. Consistent with its permits, the Keenesburg facility continues to accept only ash that is the byproduct of the coal combustion process at the power plant located on Coors Brewing Company property in Golden, Colorado. Since September, 1995 this power plant has been owned and operated by Trigen- Colorado Energy Corporation (Trigen). Agreements between Trigen and CEC, dictate that this ash will continue to be transported to the Keenesburg site until reclamation activities are complete. • All of the steam and stoker coal used for fuel at the Trigen Power Plant during the calendar year 2002, was mined and shipped from the Bowie Resources, Ltd., Bowie #2 Mine, located near Paonia, Colorado. Permit documentation and initial ash testing for the coal supply was completed, and is reconfirmed annually, thus qualifying the ash for disposal at the Keenesburg site. Annual ash "grab" samples were taken at the Trigen Power Plant at the end of 2002. Samples of both fly ash and bottom ash were collected and submitted for testing. The samples were analyzed using the Toxicity Characteristic Leaching Procedure (TCLP), and for radioactivity. Copies of the analysis reports are included in this section of the report. The ash disposal reports, which detail the monthly disposal activities at the Keenesburg Site, are found at the end of this section. AHR-2002 _82_
