Reclamation Plan Map. <br />We have enclosed two large copies of each (24"x36") for the acreage release request. <br />As we recently discussed, L. G. Everist, Inc. will submit a Technical Revision at a later date to update the <br />reclamation plan for any slight changes to slurry wall, pipeline, and topsoil pile placement. <br />During the site inspection on January 3, 2008, concrete piles were noted on site. I mentioned that the <br />concrete is collected, recycled and sold to off-site buyers. I also mentioned that it may be used as backfill <br />material for French Drains or slopes. 1 was incorrect about the backfill use. I have spoken with the site <br />superintendent, and a division manager, and found out that the concrete will only be recycled and sold. It <br />will not be used as backfill - we actually have more than enough natural material on site to use for our <br />backfill and sloping needs. In the future, if we change our minds and want to begin using concrete as <br />backfill material, we will submit the information required in Rule 3.1.5 (9) of the Construction Materials <br />Rules and Regulations for the Division's review and approval. <br />If you have questions, please feel free to contact me directly at 303-286-2247 or via email at <br />Imshults@lgeverist.com.
