Identification of Discharge other than Stormwater <br />The site was evaluated for the presence of discharges other than stormwater (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 performed 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 />stormwater 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 />intermingled with stone 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 Management Plan <br />Page 17 of 21
