6-11-1999 11:27AM FROM ADCO/BAY'ER/CHEROKEE 303 452 d515 P.3 <br />• • <br />6. As we discussed in the field on June 1, 1999 this will be a phased operation with <br />the maximum disturbance being while the last half of Phase 2 (25± aces) is being <br />reclaimed and the first half of Phase 3 (40f acres) is being mined. At no other <br />time during the entire operation will there be even close to this amount of <br />disturbance. We will add the above clarification to the text in Exhibit D -Mining <br />Plan, where appropriate, and I will calculate the bond amount based on the total <br />acreage of both phases (132 acres) needing total reclamation, which should be <br />more than enough to cover any eventuality. <br />7. In response the Allen Sorenson's comments in his 05/15/99 memo, CAMAS <br />agrees to revise the maps, text, reclamation, etc. costs as follows: <br />(A) The Regulated Construction Option for bonding will be utilized in Exhibit <br />L -Reclamation Costs with the 20% bonding option. At the end of this fax <br />is one proposal CAMAS has received to date, which is considerably less <br />than the $4.00/sq.ft. the DMG has asked us to utilize for reclamation cost <br />purposes. CAMAS is solidting further proposals, but for reclamation cost <br />purposes, CAMAS would propose to utilize a figure of $3.00/sq.ft. and <br />utilize the 20%. At such time as CAMAS actually selects a contractor, <br />DMG personnel will be consulted further on the format and details of the <br />quality assuranceJquality control plan. <br />(B) An affirmative statement will be made in Exhibit D -Mining Plan, that the <br />reservoir is being condemned by the City of Thornton to water storage as <br />the proposed source of water to fill the reservoir. <br />(C) The 35' depth and $3.00/sq. ft. will be utilized for bonding costs in Exhibit <br />L -Reclamation Costs. If CAMAS hasn't received permission from PSCo. <br />to install the slum> wall across PSCo.'s right-of-~vay before the permit is <br />ready for issuance, then 20,055' length will be utilized for bond <br />calculations. If PSCo.'s permission is obtained, then 14,168' length will <br />be utilized for bond calculations. In the first case, the 20% performance <br />bond required for the slurry wall construction will be $42I,I55; in the <br />second case, the 20% performance bond required for the slurry wall <br />construction will be $297,528. <br />3 <br />
