B. Necessary Mitigation: Back up devices on haul trucks, excavators, loaders, etc. should <br />be equipped with backup sounds of birds, frogs, or other acceptable animals. These <br />back up devices with the sounds of animals can be purchased and installed on the <br />equipment and are OSHA approved. We request that the Applicant be required to <br />purchase these backup signals to minimize the noise. In addition, this land owners <br />property is elevated 14 feet above the proposed mine and is Flanked by the mine for a <br />quarter of a mile. The applicant must be required to install a visual, sound and dust <br />control walls. Typically these walls range in height from 16 to 32 feet and can be <br />installed on all four sides of a Mining Processing Plant Area as an associated visual <br />fugitive dust, sound and visual control support system. The ENC's STC -25 modular <br />acoustical and fugitive particulate and visual confinement wall panel systems. They are <br />specially designed to effectively block related noise, fugitive particulate propagating into <br />the surrounding environment and visual impacts. <br />C. To further mitigate noisy conditions this land owner requires an earthen berm be <br />construct along this property owner's northern border. The berm would be <br />constructed of pit run topped with 18 inches of top soil. The height of the berm would <br />be 16 feet in elevation on the northwest corner and progress to 32 feet in elevation to <br />the east where an existing driveway exists the property. East of the drive the berm <br />would be 16 feet tall and progress to the east and end at the intersection of Weld <br />County Road 22 % and Weld County Road 25. The north face of the berm would be <br />terraced and benched at a 2:1 slope while the South facing slope would be 3:1. Seeding <br />with chewing fescue would be necessary and 90% coverage required. Reseeding shall <br />occur until non erosive slopes area created. We ask that the applicant purchase, spade <br />6"and 8" diameter Blue Spruce trees, transport and plant 35 trees to the south face of <br />the berm. The trees shall be planted primarily on the southern facing slope of the berm <br />on a "to -be -determined" spacing. <br />VL Objections to "Weed Control" and Proposed Reclamation Impacts: <br />A. Background: Sand and gravel mining reclamation contemplated by the applicant is weak <br />on substance and timing. Each gravel mine in the area is cover cropped with weeds for <br />years and decades. Typically, the weeds are not controlled by the operating mine. <br />Most mines in the region utilize a dozer, maintainer or loader to perform weed control <br />by leveling and pulverizing the weeds within the mine perimeter, spoil pile or <br />overburden pile. This method assures an annual weedy cover crop exposed aggregates <br />and a weedy seed distribution in close proximity of the mine. The prevailing winds will <br />cause dispersion of the weed seed and without an improved application interrupts this <br />land owner and their 25 years of farming. The applicant proposes a boiler plate <br />application response, top soiling and seeding at an exceedingly low rate when the mine <br />is complete and demonstrates a carelessness that requires revision. The applicant must <br />as a condition of the permit before mining starts develop a smart track reclamation plan <br />with specific dates, specifications and standards and fewer generalities. Given the <br />reclamation of the applicants mine is exceedingly important to the health, wellness and <br />safety of these adjacent landowners, further review, requirements and restrictions and <br />protections are required by the Windell's land owners downwind from the pit. <br />B. Necessary Mitigation: The applicant must be required to develop a living fence and <br />wind block. Weed barrier cloth 16' wide must be affixed to the soil around the <br />perimeter of the South Cell. The applicant as a condition of the mine before mining <br />
