Letter to Bryce Romig 3 February 22 2001 4. Mayflower Tailings Area The DMG, through approval of Revision SR-03 releases CMC from reclamation liability for capping a portion of the Mayflower Tailings Area. Capping of all but approximately 218 acres of the Mayflower Tailings Area was completed in 1990. The remaining 218 acres is the water pool area of the Mayflower Pond currently used for water treatment. Capping costs for the Mayflower Tailings outside the water pool area were not included in the DMG's 1998 cost estimate and are not included in the year 2001 re- estimate. The geogrid costs for Mayflower Pond have been adjusted in the year 2001 cost re-estimate assuming that 218 acres of geogrid will be required to support the Mayflower water pool fill required under the approved reclamation plan. Limitations to the release of reclamation responsibility for the 3- Dam capping project are as follows: • Revegetation responsibility release was not requested by CMC and is not included. • Area C-19 illustrated on the permit amendment AM-02 map is not released (see 9/26/00 inspection report). • The Mayflower borrow area east of the tailing impoundment is not released (see 9/26/00 inspection report). 5. Robinson Tailings Area The DMG, through approval of Revision SR-03 releases CMC from reclamation liability for capping a portion of the Robinson Tailings Area. Capping of all but approximately 219 acres of the Robinson water pool was completed in 1994. The cost to geogrid and cap the 219 acre water pool in Robinson Pond is included in the year 2001 re-estimate under tasks 74, 75, and 107c. The cost included in task #73 of the DMG 1998 estimate, to finish construction of the haul road to 2-Dam, has been eliminated from the year 2001 re-estimate. The only limitation to the Robinson capping project release is that revegetation responsibility release was not requested by CMC and is not included. 6. Eagle Valley Borrow Areas The DMG, through approval of Revision SR-03 releases CMC from reclamation liability for grading area C-14 illustrated on the permit amendment AM-02 map. The costs associated with reclamation task #92 from the DMG's original 1998 estimate and in the Year 2001 re-estimate have been eliminated from the amount of required bond. Limitations to the release of reclamation responsibility for the grading of area C-14 are as follows: • On-going maintenance of storm water controls and repair of rills and gullies may be required in area C-14. • A small zone of black shale exposed in area C-14 may require placement of viable growth media to establish adequate vegetation (see 9/26/00 inspection report). • Revegetation responsibility release was not requested by CMC and is not included.
