j) It is anticipated that sand and gravel excavation, crushing, and stockpiling at the Ashbaugh Expansion <br />site will not disturb surface water or ground water quality. Erosion control measures (Best Management Practices) will <br />be installed along the perimeter of disturbed areas and at the south margin of the site to protect the adjacent area from <br />mined area runoff and sediment. <br />k) Any onsite generated trash will be collected in an on -site dumpster and disposed at the County landfill. <br />No chemicals are anticipated to be utilized at the site. <br />1) Best Management Practices, including berms, silt fencing, and straw bales erosion control measures will <br />be installed along the perimeter of the Ashbaugh Expansion site to prevent release of mined area runoff and sediment. <br />Open excavations are not anticipated to be over 40 feet deep, MSHA approved open excavation and fall protection safety <br />measures including fencing and berms will be installed as needed. During and following mining, side slopes to the pit <br />will be graded to 3H:1 V or flatter and re- vegetated for stability. <br />m) On -site rock crusher machinery will be installed in the "gravel processing" location shown on the <br />enclosed Mining Plan map (Exhibit D) during intermittent crushing operations. It is anticipated that the crusher and <br />other equipment will be re- located to other County - operated gravel processing sites for the majority of any year. <br />n) No secondary commodities are anticipated to be extracted or produced at the Ashbaugh Expansion site. <br />No asphalt plant or concrete batch plant is planned for the Ashbaugh Expansion site. <br />o) Gravel and sand extracted from the Ashbaugh Expansion site will be utilized by Weld County Public <br />Works Department for repair and maintenance of local County roads and other County construction projects. Soils and <br />mined materials unsuitable for road construction may be stockpiled at the site. These soil stockpiles may be utilized for <br />excavation backfill and site reclamation on County- operated projects. This is a County - operated gravel pit; no <br />commercial gravel and sand sales will occur. <br />MADAVE MAshbaughORMS permit\AmendedApplication & Exhibits.doe <br />4/14/2011 <br />
