<br />NOTICE <br />OF <br />PROPOSED BACKFILL ACTIVITY <br />Pursuant to the Construction Materials Rules and Regulations, 3.1.5(9) of <br />the Colorado Mined Land Reclamation Board, the Town of Crested Butte, <br />owner of the Mountain View Pit, Permit No. M-81-002, requests <br />permission to backfill at its pit site with off-site inert material: <br />(a) The Town of Crested Butte is planning to excavate material from its <br />ice rink site within town and transport the excavated material to our <br />pit site. The ice rink is located on coke ash remains from previous <br />coal mining and coke manufacturing processes. The coke ash and <br />some brick and rock from the old coke ovens must be removed prior <br />to construction of a new concrete ice rink. <br />The Town's engineers are concerned about the structural capacity of <br />the coke ash material. However, many of the Town's paved streets <br />are constructed upon the same material. <br />(b) Approximately 1200 cubic yards will be backFilled at the south end <br />of the pit and covered with material from the pit. <br />(c) Affidavit certifying material as clean and inert is attached. <br />(d) The time frame for the backfill project is June 19 to July 1, 2001. <br />(e) The backfill project will not alter the post-mining configuration of <br />the site. <br />(f) The Town does not have a general engineering plan regarding <br />settling and voids. However, the material has been in its current <br />location for approximately 70 years. Although it does not lend itself <br />to compaction for structural purposes, it does not seem to settle <br />significantly after placement. <br />Respe tfully sub fitted, <br />VJ V ~ <br />Town of Cr ted Butte, Colorado <br />William V. rank, Town Manager <br />- S <br />. ~~\ <br />~~~'_ <br />
