<br />April 9, 2002 <br />Page 3 <br />6.4.5 Exhibit E -Reclamation Plan <br /> <br />7) The reference to establishing shoreline vegetation for the site was an error. As <br />indicated on the DMG 112 Application form, the end use of the property will be <br />rangeland (and ultimately water storage). There are no wetlands present on the site, <br />and there are no anticipated reclamation activities that would seek to create a wetlands <br />habitat on the site. As such, we ask that the Division re-evaluate its request for an <br />alternative shoreline vegetation plan. We feel that the using the seed mix as <br />recommended by the Division in its February 7, 2002 letter will be sufficient far <br />establishing vegetative cover along the shorelines of the reservoir. <br />8) Lafarge has no objection to modifying the seed mix to be used on all disturbed areas to <br />the one requested in your letter. A revised Table E-I reflecting this change is attached <br />for your review and consideration. <br />9} There will be a total of approximately 28,000 CY of topsoil salvaged from stripping of <br />the 32.5 acre area to be disturbed by mining. The total surface area to needing re- <br />vegetation during reclamation equals approximately 9.9 acres. Using these figures, <br />Lafarge can place topsoil over all disturbed areas to a depth of 18". This wil] require <br />23,958 CY, leaving approximately 4,000 CY of excess topsoil, which Lafarge will <br />either sell off site or use in backfill efforts. Lafarge will maintain the appropriate <br />volume of topsoil needed for final use in reclamation on site at all times. <br />6.4.7 Exhibit G -Water Information <br />10) Based on our discussions with the State Engineer's Office, it is our understanding that <br />we do not need a gravel well permit since we are placing a slurry wall around the <br />property and therefore will not have free-flow of the groundwater into the open pit, <br />will have no groundwater exposed to evaporation, and will have no beneficial use of <br />any groundwater. (Telephone communication with Mr. Bill McIntyre on March 27, <br />2002) <br />11) Our Substitute Supply Plan was submitted to the State Engineers' Office on December <br />21, 2001. The following information is provided in response to this question. <br />1) Water requirements, flow rates and annual volumes for the development, <br />mining, and reclamation amount to approximately 29.5 acre-feet per year and <br />are broken down as follows: <br />
