I would recommend [ha[ disposal costs for these canisters at $350.00 <br />each be applied to the reclamation cost estimate used [o establish [he bond amount. The disposal costs <br />for the rest of these chemicals can be estimated using [he unit cost tables in the demolition spreadsheet <br />of the CIRCES cost estimating software. <br />cc: Carl Mount, DMG <br />m:Unin~acsUeadville m&m msds.doc <br />
