III IIIIIIIIIIIIIIII 999 C DATE: Augusl3l, 1999 TO: Larry Rout[en FROM: Dan Mathews + RE: Roadside Mine RN-03 Cost Estimate Review Permit C-81-041 As I had mentioned to you, in conjunction with the special focus "land disturbance" inspection at Roadside, I have taken a look at the January, 1998 cost estimate which Erica Crosby did for the permit renewal. I wanted to confirrrt that all disturbed areas subject to reclamation were addressed in the estimate. As you know, the renewal has not yet been finalized. There have been a few reclamation plan changes made during the renewal process which have not been incorporated into the cost estimate, and I believe there may be a few disturbed areas/tasks which were not covered in the original estimate. Before we finalize the renewal decision, the wst estimate will need to updated as necessary. Listed below are the apparent discrepancies I noted in reviewing the cost estimate and the reclamation plan. Some of these discrepancies may not be "real". For example, sewage lagoon reclamation may not have been listed as a separate item for backfilling and grading, as it might have been included vvitl»n the backfilling and grading of the entire rail loadout area I don't know if this was the case, but I would imagine that Erica does. Before I ask Jim Stark to update the estimate, can you have Erica take a look al tite list of"apparent discrepancies" and provide her input? Reclamation Items not delineated in 1998 RN-03 cost estimate 1) Reclamation of Haul Road 2. Haul Road 2 is at the North Portal Area, extends from the Coal Creek crossing to the wck loadout at the North Portal Coal Handling area. As a result of the sp. Focus inspection, an additiona1400 feet of the road from the creek crossing to the public access road near the PSC dozer shed will need to be permitted (and addressed in reclamation plan). 2) Reclamation of Haul Road 6. HR~i is a short segment from HR-4 to the base of CRDA-2, where it connects to the "temporary refuse pile road". 3) "Reclamation of "temporary refuse pile road", which extends up the (ace of CRDA-2 refuse area from HR-0 to the refuse working bench. 4) Various disturbed areas from Table 12-1 "Distutlxd Surface Areas" total approximately 326 acres (excluding CRDA-3 proposed disturbance). Table 14-1 "Reclamation Soils Balances and Areas" specifies reclamation acreage of approximately 220 acres (excluding CRDA-3 aaeage). Total acreage specified for revegelation in RN-03 cost estimate (excluding CRDA-3 future disturbance) is approximately 189 acres. What is the explanation for the apparent acreage discrepancies, and how was the 189 acre figure derived? 5) Minewater Treatment Pond 12 was created in 1998 by building a dike through existing Pond 5, creating two ponds from one oversized preexisting pond. However there was excavation associated with completion of Pond 12, and this material was stored, along with ditch and culvert cleanoul material within a previously disturbed location nearby. Cost estimate was not adjusted to account for Pond l2 conswction, and adjacent conjwction dirt stockpile.
