DFD agrees with the findings and decision document and hereby provides OSM concurrence for the above bond release action in accordance with 30 CFR 740.15 (d) (3), and 30 CFR 906.30, Article IX, Section 24, of the State-Federal Cooperative Agreement. DRMS's Proposed Decision documents the applicant's compliance with the Colorado approved regulatory program at Rule 3.03.2, and DRMS's bond release guidelines dated April, 18, 1995. This Phase I, II, and III bond release applies to 0.2 acres consisting of the two flume sites in North Thompson Creek, the two flume sites in Middle Thompson Creek, and piezometer sites D- 1 A and D-2A. The mine water treatment system in the Developed Water Resources Area at the North Thompson Creek Mines is not currently eligible to be considered for Phase III bond release. Additionally, the underground mine workings are not currently eligible to be considered for Phase I, II, and III bond release because they are the source of the water that is treated in the mine water treatment system in the Developed Water Resources Area. The Colorado Department of Public Health and Environment's Water Quality Division determined that mine water discharging from the No. 3 Mine does not always meet water quality standards without treatment. DRMS Rule 4.05.2(2) requires that a water quality treatment facility be maintained until either the discharge continuously meets the effluent limitations without treatment, or until the discharge has permanently ceased. OSM finds that MINREC, Inc. has met or exceeded the requirements for Phase I, II, and III bond release on the 0.2 acres of land as described above. DRMS currently holds a performance bond in the amount of $100,000. The current liability amount is $42,115.00. This action will release $32,115.00. DRMS has determined that the remaining bond amount of $10,000 is sufficient to
