Deep Cut LLC - 22 West Pit Page 8 <br /> Adequacy response 01 Permit # M-2017-032 <br /> but while its quality is unknown we believe that it would serve as growth medium if used <br /> on the above water areas on the new lake shore as shown on Map Exhibit F-1 - <br /> Reclamation Map Exhibit (Option 1) . <br /> 16) The applicant submitted a proposed seed mixture on page 15 of the application which includes yellow <br /> sweetclover. This species is now considered to be invasive (possibly a noxious weed) in Colorado. <br /> Therefore,please remove or replace this species from the proposed seed mixture. <br /> I have revised the seed mix on Page 15 by removing the Yellow Sweet Clover as you <br /> suggest and adding White Prairie Clover so the seed mix will have approximately 47 <br /> seeds per square foot. <br /> 17) On page 16 of the application, the applicant states that if needed, materials existing on site in the Plant <br /> Site may be used to armor the lake slopes or as fish habitat in the lake. This material may consist of <br /> broken concrete or other materials suitable for that purpose. Please be advised, if these materials are to <br /> be used for reclamation (slope armoring or pond backfill), costs for completing this task(s) must be <br /> included in the reclamation bond estimate. Otherwise, the Division must include bond costs for <br /> hauling these materials off site for proper disposal. Please be sure to include costs in Exhibit L for <br /> handling the existing materials on site, whether for reclamation use or removal from the site. <br /> This is existing material (refuse) on site and the Division is not responsible for cleaning up <br /> the site from activities done prior to permitting. It is not considered waste until it is <br /> disturbed by mining at which time it can be disposed on site since it was on the mine area <br /> pre permitting. The key is MAY USE, and was added to give the operator flexibility to <br /> improve the reclamation without being required to do so. If the plan had been a firm plan <br /> then the location of the armoring or fish habitat would have been shown on the <br /> Reclamation Map. As I recall in the law, anything found on or generated on the site can <br /> be buried on site as long as it is not detrimental to the environment (34-32.5-(116)(4)e). <br /> The material in question is well aged inert material (concrete) that if disturbed it would be <br /> easier and cheaper to dig a hole and burry it then haul it off site for disposal. The new <br /> landowner may not want it wasted and will choose to keep it for use on the lake areas he <br /> owns not in the permit area. <br /> Please be aware that if any material existing outside of the permit area is used for reclamation of the <br /> permitted area,the Division would consider this to be offsite damage. <br /> Thank you for the information. <br /> 18) On page 18 of the application,the temporary grass species proposed for topsoil stabilization is Crested <br /> Wheatgrass. Although this grass species can be helpful for quick stabilization, it is not compatible <br /> with native grasses. If used for topsoil stabilization, this species would become part of the topsoil <br /> seedbase and potentially interfere with the growth of desired native grasses when the topsoil is used <br /> for reclamation. Please replace this species with one that is more compatible with native grasses. <br /> Deep Cut will commit to using 40.0 #'s-PLS of Western Wheatgrass, per acre of surface <br /> area of soil stockpiles. This works out to about 80 seeds/sq-ft. I made the revisions to <br /> page 18 and supplied a copy for the file. <br />
