proposed permit area from mining and reclamation activities will be obtained. The permit <br /> includes the continued updating and implementation of a site Stormwater Management <br /> Plan designed to prevent the contact and transport of potential contaminants to surface <br /> waters by stormwater flows. <br /> The depth to groundwater fluctuates by a couple of feet depending on the season, but <br /> averages about 10 feet below ground surface. Due to the absence of large quantities of <br /> potential pollutants on site (no on-site processing or concrete or asphalt production), the <br /> mining and reclamation operations are not likely to affect groundwater quality on <br /> or off the site. As stated above, mining and reclamation activities shall operate under a <br /> CDPS permit and Stormwater Management Plan. The plan provides for regular <br /> inspections of potential contaminant areas such as mobile equipment and fuel or <br /> lubricant storage locations. Inspections and best management practices are <br /> incorporated into the plan to protect both surface and groundwater quality. <br /> Aggregate Industries—Tucson South Amendment—MLRB 112 Permit Application <br /> Exhibit G- 10 <br />
