The Division has reviewed your Mazch 7, 2003 revised reclamation cost information for the <br />Larimer Pit. The Division is in agreement with a majority of these costs. However, the Division <br />has calculated a total reclamation of cost of $300,000 (see attached costs). This total costs <br />includes an average cost acre for revegetation of $500/acre which includes seedbed preparation, <br />seed cost, fertilizer, and mulch. Also, we have included additional costs for dewatering of pits 6- <br />9, tree & shrub establishment, equipment mobilization & demobilization, and indirect costs. <br />The Division is willing to discuss and adjust these costs, if appropriate. Please respond. <br />12. I have attached a copy of the Division's "Guide to Specification Preparation For Slurry Walls <br />and Clay Liners" in the event that Loveland Read Mix wishes to pursue a regulated construction <br />option (and bonding) for the Pond 2 liner to be installed. Please contact the Division at your <br />eazliest convenience if you wish to pursue the regulated construction option rather than bonding <br />for 100% liner installation. <br />
