,• 2.05.4 (2) RECLAMATION TIIvIETABLE CEC is intent on the discontinuation of coal mining operations at the Keenesburg Mine, and the planned progression ofthis site to serve instead as an ash and mine waste rock (A/MWR) disposal facility, as an integral part of the reclamation process. At this time A-Pit is fully reclaimed. Other areas, including portions of the access roads (formerly haul roads) to A-Pit and the south end of B-Pit, are in various stages of reclamation. The Evaporation Ponds, which were situated in the northwest corner of the permit azea and the Tipple facility, formerly located in the northeast part of the permit area were removed and reclaimed during 1994 and 1995. CEC continues to work towards total reclamation of all areas not related to the ongoing A/MWR disposal operations. At the present annual A/MWR. disposal rates, about two (2) acres per year can be backfilled and graded in the pit disposal areas. However, the placement of topsand on such small areas often restricts normal heavy equipment movement. CEC believes that when an azea of approximately 10 to 20 acres has been backfilled and is readily available for topsanding, fertilizing and final revegetation, it should then be done. CEC estimates that this opportunity may only occur once or twice before the next permit renewal and during each 5-year period, thereafter. The largest acreage parcel to be seeded will likely be linked to the last year of A/MWR disposal, which is now estimated to be 2010. The stockpiled-soils and facilities areas will also be ready for final reclamation at or about this same time. CEC has been granted a variance in the requirement for contemporaneous reclamation for the B-Pit area until March, 2004. This variance may need to be extended for additional time periods, depending on the continued rates of A/MWR disposal, and the extent of"air space volumes" requiring further disposal activity to achieve final reclamation contour configurations for the site. Based on agreement between CEC, CDMG, Weld County Department of Health and Colorado Department of Public Health and Environment, memorialized in Technical Revision 32, the East Perimeter Ditch, the West Perimeter Ditch and Sediment Pond 2 join the previously approved Dugout Pond as permanently retained surface features following mine closure. CDMG is formally appraised of the reclamation activities at the Keenesburg Mine through the Annual Hydrology and Reclamation Report (AHR report) which is prepazed and submitted by CEC at the end of February of each year, unless otherwise agreed. This report addresses the previous calendar year's reclamation activities. 117 7/99
