Impacts Reduced air quality due to emissions from construction equipment, trucks, earth moving machinery, asphalt production, and temporary boilers, etc. Increased turbidity in surface waters due to erosion from site clearing, earthwork, and road and building construction. Pollution of surface waters from sanitary sewage, construction waste disposal, and site stormwater runoff. Pollution of surface waters from fuel or other hazardous material spills. Table 8-2 lmpacts and Mitigating Measures Mitigating Measure The chosen location of the construction site is approximately 2 km away from the nearest populated area which effectively elimi.pates the impact of reduced air quality on the local population. All diesel and gasoline powered equipment used on site will be properly maintained to ensure efficient operation. Silt fences and/or hay bales will be erected in the areas of soil disturbing activities. Vegetation will be maintained and/or replaced as necessary. Sanitary sewage will be collected and removed by tank truck until an onsite treatment plant is constructed and operating properly. Construction waste will be disposed according to local regulations. Site stormwater runoff will be directed to an onsite stormwater retention pond intended to reduce siltation and allow for floating oil to be skimmed. Fuel storage tanks will have secondary containment sufficient to hold the volume of the largest tank plus 10%. Hazardous materials will be stored in approved structures providing fire prevention and secondary containment capabilities. An Emergency Response Plan will be prepared detailing the procedures to be followed by the contractors onsite emergency response team to prevent spilled material from reaching surface waters. In the event spilled material reaches a surface water body procedures to minimize the impact by rapid containment prior to cleanup will be implimented. PAGE 8-3 b\$ J
