Pre -Mining — Slope 2: 0.107 tons/acre/year <br />The 2019 sedimentology evaluation data shows post -mining condition sediment loss to be <br />less than pre -mining conditions. <br />Post -Mining — Slope 3: 0.055 tons/acre/year <br />Pre -Mining — Slope 3: 0.094 tons/acre/year <br />The 2019 sedimentology evaluation data shows post -mining condition sediment loss to be <br />less than pre -mining conditions. <br />Summary and Conclusions <br />The Division has completed its review and evaluation of the SL-19 partial Phase II Bond Release <br />application submitted by Colowyo for the Colowyo Mine. The Division proposes to approve this <br />Partial Phase II Bond Release on 238.2 acres for portion of the East and West Pits and GFO1. Based <br />upon a review of the mine permit, the applicant's bond release application, and site inspections, the <br />Division finds that Colowyo has completed topsoil replacement and vegetation cover requirements <br />per Rule 3.03.1 and Coloywo's PAP. The Division finds that Colowyo has achieved the <br />requirements for partial Phase II Bond Release at the Colowyo Mine. <br />V. PROPOSED DECISION <br />Based on the observations in Section IV above, the Colorado Division of Reclamation, Mining, and <br />Safety proposes to approve Colowyo's request for a partial Phase II bond release for the Colowyo <br />Mine. This proposed decision will release the applicant of Phase 11 reclamation liability on 238.2 <br />acres for portion of the East and West Pits and GFO1, as shown on Figure 1 at the end of this <br />document. <br />The Division holds a performance bond in the amount of $115,000,000.00 for the Colowyo Mine. <br />The Division has calculated the amount associated with the partial phase II bond release area and it <br />totals $477,276.00. The Division estimates its cost to complete remaining reclamation work at the <br />Colowyo Mine to be $114,085,312.00. This amount is sufficient to assure completion of the <br />remaining reclamation work to the Colowyo Mine if the work had to be performed by the Division, <br />including the cost of reestablishing vegetation on any revegetated areas, should those areas fail. <br />With the releasable amount of $477,276.00, the Division will still hold a bond in the amount of <br />$115,000,000.00 which is $914,688.00 more than the minimum required liability to fully reclaim <br />the remaining disturbed areas at the Colowyo Mine. <br />Any person with a valid legal interest which might be adversely affected by this proposed decision <br />may request a formal public hearing before the Mined Land Reclamation Board in accordance with <br />Rule 3.03.2(6). Public notice of this proposed decision will be published twice in the Craig Daily <br />Press as soon as possible. Requests for public hearing must be submitted to the Division in writing <br />within thirty days of the first publication in the Craig Daily Press. If no hearing is requested within <br />those thirty days, the Division's decision will become final. <br />Proposed Decision and Findings of Compliance October 26, 2020 <br />Partial Phase II Bond Release SL-19 Page 8 <br />
