<br />review of the 1999 AHR for Eckman Park. Natural variation in runoff and snowpack would dwarf <br />an potential increase in runoff due to mining. Storage capacity in Pond A would also further <br />reduce peak flows due to alteration of the hydrologic cover. No significant change in surface <br />water quantity was identified during mining nor is any apparent from data collected over the <br />reclamation liability period. <br />In summary, Area 41 in Eckman Park does not impact the surface or ground water system to any <br />significant degree. With regazd to this azea, the operator has minimized the impact to the <br />hydrologic balance and prevented material damage outside the permit boundary. <br />III. CONCLUSION <br />The original performance bond for the Eckman Park Mine and Energy Mines No. 1 and 2 was <br />$10,585,393.00. The Division released $1,705,393.00 in reclamation liability in 1987 for successful <br />backfill and grading of 2,397.9 acres. All of the facilities located along the base of the dip slope on either <br />side of Foidel Creek have been transferred to the underground Foidel Creek Mine permit (C-82-056). <br />Liability for reclamation of these facilities, the former mine office known as the "brown palace', and <br />sediment ponds B, C, D, E, F, G, and T were transferred to Foidel Creek Mine permit, as well. A Phase II <br />and III bond release for final reclamation success in the Block C azea in Eckman Park in was approved <br />October 1996. The Block C (SL-03) approval released liability in the amount of $34,600.00. CYCC <br />chose not to reduce the bond instrument at the time of the approvals. A Phase I bond release (SL-OS) in <br />the amount of $4,645,843.00 was granted to 610 acres of successful backfill and grading in areas 61 and <br />51 W in Eckman Park in December 1996. CYCC chose to reduce the bond by $4,645,843.00 in April <br />1997. Phase 11 and III bond release on 477.4 acres a[ Eckman Park Energy Mine No. 2 was approved <br />March 30, 1998 (SL-06). SL-06 released $95,480.00 and all remaining reclamation liability on the <br />Energy Mine No. 2 portion of the C-81-071 permit. The remaining reclamation liability bond required for <br />the Eckman Park, Mine 1, and Eckman Park and Energy Mine No. 1 complex to afrer approval of SL-06 <br />was $ 4,104,077.00. In September 1998, CYCC transferred reclamation liability for 1.5 acres, known as <br />"Trudy's comer" or the Equipment Storage Area (MR-88), to the Foidel Creek permit (C-82-056). The <br />active underground operation of the Foidel Creek mine uses the 1.5 acre site for drill rig storage, safety <br />training and equipment storage. Approval of MR-88 reduced the reclamation estimate for Eckman Park <br />and Energy Mine No. I by $2,346.00. <br />The Division currently holds a performance bond of $5,939,550.00. Rule 3.03.1(2) and Rule 3.03.1(3) <br />require the Division to release no more than 85% of [he applicable bond until the permitee has <br />successfully completed all surface coal mining reclamation operations in accordance with the approved <br />reclamation plan. The Division is required to retain a minimum reclamation bond of $1,561,099.00. <br />Colorado Yampa Coal Company: SL07 Findings I I/00 page 13 c:\jhb\C081071\SL07 rnd doc <br />
