for these soils in Orange County have been for cropland, pasture or woodland. The soil has a <br /> high potential for corn, soybeans, tobacco, small grain, hay and pasture forage. Principle <br /> limitation for agricultural use are slope surface runoff due to moderate permeability, and erosion <br /> potential. <br /> Tatum soils comprise the remaining 40% of the expansion area. In the past, these soils have <br /> been predominately used as pasture or woodland due to slope, shallow depth of bedrock and <br /> erosion potential once ground cover is removed. Potential for hay and pasture forage is <br /> moderately high. <br /> C. Expansion Alternative <br /> Expansion of the quarry as described in Section 2.0 includes expansion of the quarry operation, <br /> relocating SR 1104 and locating a new asphalt plant. <br /> A new increase of impervious surface of approximately 0.2 acres will occur with this alternative. <br /> Traffic volumes resulting from quarry activities are anticipated to remain consistent with existing <br /> volumes, since no increases in daily mining activities are projected. Benefits from the alternative <br /> include additional tonnages of crushed stone available for manufacturing and construction <br /> activities, expanded reservoir capacity (approximately three billion gallons) for future use, as well <br /> as an additional 100 acres of protected buffer land surrounding the new reservoir to be acquired <br /> by the Orange Water and Sewer Authority. The expanded quarry area will not result in an <br /> increase in impervious surface area. <br /> Since the expansion of the quarry will not increase the rate of stone production but only increase <br /> the life of the site, traffic volumes are expected to remain consistent with existing volumes. <br /> Because the current economy reflects a decrease in building and other construction related <br /> activities, quarry records were examined for the period of 1988 through 1990 to determine <br /> demand for the crushed stone. Resulting traffic volumes revealed that traffic generated by the <br /> facility varied only 7 percent (344 VPD in 1988, 368 VPD in 1989, and 346 VPD in 1990) during <br /> the three year period. <br /> The new asphalt plant will be relocated to an area east of the existing quarry pit on the east side <br /> of relocated SR 1104. The existing plant will be dismantled,and the site stabilized, re-graded and <br /> vegetated. The new asphalt plant site will include approximately the same amount of impervious <br /> surfaces as the existing plant site. The new plant will include state-of-the-art environmental <br /> 2-5 <br />
