Identification of Discharge other than Stormwater <br /> The site was evaluated for the presence of discharges other than stonnwater(except for those <br /> that are permitted)on September 19, 2005 by Steve Compton of Lafarge. The method used was <br /> a visual site inspection. During this inspection, there were no unpermitted non-stormwater <br /> discharges identified. Further, we have reviewed subsequent stormwater inspections at this site <br /> and the results of subsequent inspections were consistent with the inspection perfonned on <br /> September 19, 2005 unless otherwise noted and addressed on subsequent inspections. <br /> Water associated with portable wash plants for processing aggregate, mine dewatering as <br /> necessary, and water used in the production of concrete are the primary sources of'non- <br /> stonnwater on site. Mine dewatering is monitored as outlined above to ensure no compliance <br /> with our permit restrictions. All other sources are contained within the site and are not <br /> discharged with stormwater. Water stored and applied on site for dust abatement is periodically <br /> utilized on the yard site and the access road to suppress fugitive dust. Applied dust control is not <br /> applied in excess amounts that would result in an off-site discharge of liquids. Dust abatement <br /> is not necessary during precipitation events; therefore, no non-storm water at the site is <br /> intenningled with storm water runoff. Water and other liquids utilized in other peripheral uses <br /> and in the production of aggregate are contained within the plant. Any mechanical failure with <br /> the potential to allow a surfaces release would be addressed through the site's spill response or <br /> emergency response protocols, free liquids would be isolated and adsorbed, and adsorbents <br /> properly disposed. <br /> Currently, no stormwater or commingled process water are in sufficient quantities to discharge <br /> from the site. Should subsequent water uses be initiated on site, these water sources will be <br /> identified in the table below: <br /> Permitted <br /> No Process <br /> Types of Discharge Discharge Water Unpermitted Exempt Control Measures <br /> Mine Dewatering X <br /> 35"Avenue Pit,Concrete,&Asphalt Facilities <br /> Storm Water IVlanagemmt Plan <br /> Page 17 or21 <br />
