DEPARTMENT OF NATURAL RESOURCES <br />DaviO N. Getches. Eaecuiive Director <br />MINED LAND RECLAMATION DIVISION <br />DAVID C. SHELTO N, Dlreetor <br />Richartl D. Lamm <br />Governor <br />DATE: April 25, 1985 <br />T0: Gregg Squire <br />FROM: Jeffrey Deckler /fj' <br />RE: Animas Mid-term Review <br />I have reviewed the Animas Mine permit application and revisions. My comments <br />are outlined in the following paragraphs. <br />A review of the bonding calulations is included below. Rough calculations may <br />be found attached. These calcu]ations inc]ude the assumption that material <br />will have to be imported to the site in order to achieve AOC in the proposed <br />refuse area. The bonding requirements for the Animas Mine are as follows: <br />Item Cost b Est. Source <br />facilities Removal ntmas, D <br />Portal Sealing 2,500 Animas <br />Backfilling & Grading (Helen) 11,089 MLRD <br />Backfilling & Grading (Refuse) 173,458 MLRD <br />Non-toxic coversoil (Refuse) 30,480 Animas <br />Ripping facilities area 5,770 MLRD <br />Topsoiling 11,699 MLRD <br />Revegetation 9,482 Animas <br />Loadout reclamation 15,837 Animas <br />Sub-Total ~7$;3a5 <br />Administration @ 10% 37,830 <br />Total Cost ~5 <br />The bond costs above were estimated using the Rental Rate Blue Book and the <br />1985 Means Construction Cost Data Book. Currently the mine is bonded far <br />b146,634. The items which significantly increased in cost were: prep pT~nt <br />demolition, conveyer demolition, and earthmoving. Earthmoving costs increased <br />as a result of the current need for fill in the north portal area. The <br />present reclamation plan has not considered this. Rather, it considers a <br />situation where the area has been filled with coal refuse. Due to the <br />inactive status of the mine, this refuse does not exist. It should also be <br />noted that the operator has included documented contractor cost estimates for <br />machinery which are lower than the rates used in my estimation. Due to the <br />large discrepancy in calculation's we may wish to revise the above estimate <br />using these rates. <br />423 Centennial Building, 1313 Sherman Street Denver, Colorado 80203 Tel.
