Mr.Joel Renfro <br /> RE: 5JPit M-2024-032 <br /> October 7, 2024 <br /> In addition to the facilities described above, the portable scale house has approximate <br /> dimensions of 30 feet by 10 feet and the associated truck scale is 72 feet by 12 feet. Although <br /> the truck scale is fully portable, it includes four (4) concrete beams, each 16'x3.5'x2'. <br /> Following mining, the beams can be relocated with the scale or demolished and left on-site. <br /> 3. Mining is expected to occur in one phase, but only 5 to 10 acres will be involved in active <br /> mining at any one time.It is anticipated that at maximum operation,approximately 3 to 5 acres <br /> will be mined annually. The area actively being mined will also have limited reclamation <br /> activities occurring simultaneously. Active reclamation that includes grading, addition of <br /> topsoil, and seeding will also be taking place on an additional 5 to 10 acres where mining <br /> activities were recently completed. The area containing the processing, recycling, and asphalt <br /> facilities will have been previously mined and mostly reclaimed. However, the facilities area <br /> will require final grading, addition of topsoil, and seeding following completion of the <br /> operation. <br /> 4. The employee parking lot will not be paved,but will be maintained with pit-run sand and <br /> gravel material. <br /> 5. No internal roads are expected to be paved,but internal haul roads with consistent,high <br /> traffic volumes will be maintained with pit-run sand and gravel material. <br /> 6.4.5 Exhibit E—Reclamation Plan <br /> 6. Yes, although the earth moving equipment will likely include dozers, loaders, scrapers, and <br /> excavators, any additional equipment necessary for mining and reclamation operations will <br /> also be used.Other equipment may include,but may not be limited to,water trucks,haul trucks, <br /> motor graders, compactors, and various sizes of dozers. <br /> 6.4.11 Exhibit K-Climate <br /> 7. Average monthly wind speeds (based on daily cumulative wind speed) were calculated from <br /> National Weather Service data collected at the Northern Colorado Regional Airport (NCRA) <br /> for the period July 2020 — August 2024. The NCRA is approximately 20 miles south of the <br /> project site. Additionally, average monthly wind speeds were obtained from the Western <br /> Regional Climate Center(period 1961 — 1990) for Denver, Colorado and Cheyene, Wyoming. <br /> Wind speeds from these locations are presented in the table below. <br /> (blue earth Page2of4 <br /> SOLUTIONS <br />
