Colowyo's estimate does not appeaz to include a cost for removal of equipment and <br />debris (bone yazds). Please revise the estimate to include these disposal costs. <br />8. CDMG was unable to verify Colowyo's estimated seed costs. Our estimate is $170.60 per <br />acre, Colowyo used $94.00. Please provide documentation in support of Colowyo's costs or <br />revise the cost estimate. <br />9. Road maintenance costs estimated by Colowyo for truck and loader operations were <br />compazable to CDMG estimates. Based on observations at mining and reclamation operations <br />similaz to Colowyo, CDMG believes that the road maintenance needs during scraper operations <br />should be increased to 50%. Please revise the estimate to include the cost of additional road <br />maintenance. <br />10. The volume figures provided on page D-23 for facilities azea regrading aze not consistent <br />with those on page A-16. Please revise or remove page A-16. <br />11.

Please include grading <br />costs for all facilities areas. <br />12. Map 12, Hydrology, shows a ditch at the Prospect pond, extending in a northeasterly <br />direction.

The as-built map indicates a height of 20'. Please verify the height. <br />b. CDMG could not verify Colowyo's estimated embankment width for the West Pit <br />pond. The as-built drawing indicates a top width of 20'; Colowyo's estimate is based on <br />17'. Please verify the width. <br />c. CDMG could not verify the Gossazd Loop pond embankment. What is Colowyo's <br />source (map, permit page, etc.) for the length? <br />d. It does not appear that Colowyo applied a spoil pile factor to the pond regrading tasks. <br />This factor beazs on productivity estimates. Please provide a copy of Colowyo's <br />
