consumption, washdown, and fire protection. A storage tank will be built on site and <br />sized appropriately to ensure adequate water for fire protection. Daily water usage for <br />operation of the transfer station is expected to be in the range of 650 to 900 gallons per <br />day. Based on the size of the property and the previously discussed recharge rate of <br />about 150 gallons /day /acre, infiltration into the site and associated buffer surfaces will <br />exceed expected usage. With the additional infiltration of a large area of County -owned <br />land at the existing landfill and future park area, the water usage at the site is not <br />expected to have an impact on the quantity of water available to the neighboring <br />residences or farms. <br />A separate septic tank and drainfield system will be designed to handle the minimal <br />sanitary wastes generated at the facility. A site evaluation by the Orange County <br />Environmental Health Services has found that some suitable soils exist on the property <br />that should be adequate for the septic drainfield. The concept of a pump and haul system <br />for the wash -down water has been approved by the North Carolina Department of <br />Environment, Health, and Natural Resources (NCDENR) Division of Waste Management <br />and Division of Water Quality. <br />No solvents or similar type cleaning fluids will be used in wash -down operations of the <br />transfer. No long -term outdoor storage of waste or other materials will be allowed. <br />4.10.2 Surface Water Resources <br />To improve stormwater runoff quality, BMPs will be implemented in the development of <br />storm -water management and control measures for those areas outside of the building <br />envelope. <br />Wastewater will originate during normal facility operations primarily from equipment <br />and tipping floor cleaning and sanitary wastes. The wash -down system will be designed <br />with storage and containment for the capture of all wash waters resulting from station <br />operation. The wastewater will be recycled on site, and the residue will be hauled off site <br />for disposal. No wash -down water will be discharged on site. <br />As referenced in Section 3.10.2, the Orange County Erosion Control Division determined <br />that there are no streams on the Paydarfar property, and the tract will not be subject to <br />stream buffer rules. <br />Environmental Assessment — Paydarfar Site <br />17 September 30, 2009 <br />
