Sherman St. <br /> Denver, CO 80203 <br /> Re: Surety Reduction Request M-1980-183 <br /> Mr. Ebert, <br /> As discussed in the spring of 2019 field meeting and follow-up via email, Brannan has prepared <br /> a surety reduction request for the Brannan Pit 29 facility, with reclamation permit number M- <br /> 1980-183. <br /> While significant reclamation projects remain, many reclamation works have been completed, <br /> including the slurry wall construction and leak test, a majority of the earth work for slopes, and <br /> construction of the French drain. The reclamation items from the most recent reclamation cost <br /> worksheet from AM 2.2 for which surety reduction is requested are as follows: <br /> • Reduce bonding requirement for 474.02 hours of earth work for a fleet of 2 dozers to 50 <br /> hours of earth work for a fleet of 2 dozers <br /> o Reduction from $240,639.00 to $25,383.86 <br /> o Rationale: The majority of slopes on reservoir I and reservoir II have been <br /> completed. There is a section of the south side and the southeast side of <br /> reservoir II that requires banks to be graded, and the slopes to meet 3H:1V, and <br /> is estimated to consist of 50 hours of dozer work at a fleet size of 2 to be <br /> completed. <br /> o It is possible that a specific design or analysis of existing slopes will be submitted <br /> in the future as an alternative to the AM-01 reclamation plan or default slope <br /> standards. <br /> • Removal of bonding requirement for rip rap from banks of reservoirs <br /> o Reduction from $600,000.00 to $0.00 <br /> o Rationale: AM-01 reclamation plans show rip rap on banks above original <br /> ground surface. There are no banks above the original ground surface. This was <br /> agreed by Jared Ebert in the attached letter, dated April 23, 2019. <br /> 2500 East Brannan Way I Denver I CO 80229 1 303.534.1231 Tel 1 303.534.1236 Fax <br /> www.brannanl.com <br />
