4.8 Air Quality The facility will have minimal impact on ambient air quality. The facility shall be fully enclosed and the heating, ventilating, and air- conditioning (HVAC) systems will be provided to maintain indoor air quality and minimize potential air emissions. The building envelope will be constructed from environmentally preferable materials that minimize life -cycle environmental impacts, resource depletion, and human toxicity. The project will generate up to 70 vehicle trips per day. This includes County, Town(s) and commercial haulers and tractor trailers hauling refuse to the landfill. While currently there are no trucks entering the property, there is already established daily traffic on both Millhouse Road and Eubanks Road. The collection vehicles will be restricted to certain County roads to reach the property. The transfer station is located near the waste generation centroid, which will minimize the overall collection truck traffic volumes across the County to the transfer station, also minimizing the overall carbon footprint. Air quality impacts during construction are expected to be minimal. Emissions from construction vehicles will represent a short-term air quality impact from dust and equipment emissions. 4.9 Noise Levels The proposed project will increase noise levels over current conditions. However, this increase will be limited to the noise associated with the collection vehicle and tractor trailers entering and leaving the site. The transfer building will be totally enclosed and constructed with an acoustic building shell (interior insulation and liner panel system) to contain noise within the building. On- site traffic and noise levels will be controlled by maintaining the natural wooded buffers around the site. The transfer station will operate only during daytime hours when the noise produced at the facility will be compatible with other activities in the area. 4.10 Water Resources 4.10.1 Groundwater Resources Although public water and sewer utilities are available in the area, it is uncertain whether these utilities can be made available to the site. Therefore, planning for the facility is proceeding under the assumption that no public water or sewer will be available at the site. A groundwater well already exists on the property, although Orange County ERCD is planning to use that well for its County -wide groundwater monitoring program. If this well is not used for the transfer station, another well will be drilled to provide water for Environmental Assessment — Paydarfar Site 16 September 30, 2009
