Binns subject: Golden Eagl cl ati Cost Estimate date: August 13, 1 lames 5. Lo<hhearl Eaecm rve Director Michael B Long Division Director Kent, after searching for, and not finding Harry's documentation or computer disk from when he updated the estimate in 1996... I basically started from scratch. I removed costs that we have granted Phase I bond release , SL-O1. I included waste pile subsoil costs, But kept all topsoil costs in the estimate, until such time as phase II bond is applied for and released. I removed any costs associated with TR-47 approval. From the public SJ_-02 file I had, it appears that SL-02 has not received approval as of this date. To keep the process "clean". T kept the SL-02 costs in this estimate, and labeled them as such so that they will be easily extracted when SL-02 reaches a decision. One cost 1 could not find depth and diameter detail on in the permit was for sealing of the 5 monitoring wells. I did include a cost for ongoing water monitoring as required by the permit. If there are tasks that should remain in the estimate that weren't readily apparent to me, please send me a memo (or e-mail). On the ditch reclamation, I was unsure on what length of ditches remain out there so I just took Harry's cost for ditch reclamation. Based on your observation of the site, does that cost need refinement? Now we start getting into that weird territory with reclamation cost liability estimates. We have released 60% of the costs of back filling and grading, demolition, etc. (SL-O1). Remaining tasks to be completed (or requested for release) are less than that remaining 40% of the bond that we are required to keep based upon rule 3.03.2(a) So You (lead specialist) may want to keep an understanding of how much we can release based on regulatory limits, vs. what we estimate is actually necessary to reclaim whatever is remaining. I will be back briefly on 8/24, then I expect to back in the office on August 28th. So if you need me to define/refine something with this, you'll have to catch me then. I did not copy the disk, so please keep the disk with the estimate.
