1 <br /> Jared Ebert <br /> July 8, 2019 <br /> Page 2 of 18 <br /> Highway 7, the stockpile is in an area that is not anticipated to be flooded during a 100-year <br /> storm. On the south side of Highway 7, the stockpile is in an area that is considered <br /> ineffective flow area due to the contraction effects of the bridge. An ineffective flow area is <br /> an area where ponding will occur but does not convey flows further downstream and is <br /> typically found adjacent to bridges and culverts. Stockpiles placed within and ineffective <br /> flow area are not expected to contribute to increases in water surface elevation. Since <br /> stockpile placement in each of these areas is not expected to increase water surface <br /> elevations, the restrictions on length and width of the stockpile are not pertinent. Exhibit D <br /> has been revised with language describing the justification for differing stockpile <br /> dimensions. <br /> Rule 6.4.4, Exhibit D — Mining Plan <br /> 4. Page D-1 indicates the Applicant is working with the Landowner to obtain a right-of-way easement <br /> for a conveyor on Tract M. According to Exhibit N and Maps C-1, the Applicant owns Tract M. <br /> Please clarify and/or otherwise revise this discrepancy. <br /> The reference in Exhibit D is incorrect. Tract J is owned by the City of Thornton and the <br /> applicant has contacted the City and is working toward an agreement. <br /> 5. Page D-2 indicates the Todd Creek water well and associated United Power electric line on the <br /> west side of the West Area will be removed. Please clarify, are these structures A-5 and A-11 <br /> depicted on the Exhibit C-2 map? If so, does Todd Creek or the applicant own the water well to be <br /> removed? Also, please either provide documentation the Applicant has permission to remove the <br /> United Power electric line, and/or if this information has already been provided, please revise this <br /> page to indicate where in the application materials this documentation has been provided. <br /> Structures A-5 and A-11 are depicted on the Exhibit C-2 map. The applicant owns the well <br /> and associated improvements. The Applicant has contacted United Power regarding <br /> removal of the electric line serving the abandoned well. It is our understanding that United <br /> Power will remove the line. The line will remain undisturbed until the details of how the line <br /> will be removed are confirmed with United Power. We will forward documentation of the <br /> process to the Division upon receipt. <br /> 6. Please specify the depth(s) the topsoil will be stripped. Please revise page D-2 to indicate this <br /> information. <br /> Average depth of topsoil to be removed is 6". Exhibit D has been revised to reflect this <br /> information. <br /> 7. Page D-3 indicated Phase 1 (South area) will be mined wet and may also be actively dewatered. If <br /> this phase is planned to be wet-mined, please explain the purpose of dewatering? <br /> Aggregate Industries has reevaluated the mining process on this portion of the site. Phase 1 <br /> will be dewatered and mined using traditional perimeter dewatering trenches and removal of <br /> the material via excavators and trucks. Dewatering will continue until the area is backfilled <br /> to the pre-mining elevation. <br /> Aggregate Industries—WCR,Inc <br /> 1687 Cole Blvd Suite 300 <br /> Golden,CO 80401 <br />
