emissions: the total gas emissions of the plant should be equivalent to those arising from heating a 3,000 square foot residence. In October, 1985 a fatal fire and explosion occurred in the asphalt heating system. More than 95 percent of the approximately 400 gallons of spilled fuel oil was contained behind an earthen berm as firefighters used between 30,000 and 40,000 gallons of water to hose down the flames. This material was subsequently cleaned up and disposed of off site under direction of the North Carolina Division of Environmental Management. No contamination occurred to either Phil's Creek or OWASA's Quarry Reservoir. In February, 1992 an Environmental Site Audit was performed for the entire asphalt plant site by consultants hired by the Nello Teer Company. Twenty-four soil borings were performed and samples were taken for laboratory analysis, All soil samples and borings were screened for volatile organic compounds. Boring readings and analytical results indicate two areas of concern. The first area was at the concrete pad where asphalt truck beds were sprayed with fuel oil (a practice no longer used). The second area was at the spill containment basin. Contaminated soil was removed from these areas and the area resampled. Analytical results confirmed that all contamination had been removed. 3.5.6 Noise Noise in the project area is typical of that attributed to a rural land use. In such a setting, residents experience intermittent increases in noise levels attributed to traffic on nearby roads or the passing of a low flying aircraft. At the project site there are several sources of noise. These include trucks entering and exiting the quarry, stone crushing and screening activities, mining equipment loading and hauling rock out of the quarry pit and blasts which occur on the average 1 1/2 times per week and last less than 1/4 of a second. However, due to the fact that noise travels in a straight line and the site is almost entirely bermed, noise generated at the site is muffled to background levels at which it is experienced by residents of the project area. To demonstrate this, sound level measurements were taken at various locations in the project area on March 3, 1992, Measurements were taken when the quarry was in full operation utilizing a General Radio Type 1565A Sound Level Meter set to read in the A scale or that scale most representative of the human ear. The meter was calibrated prior to use 3-23
