r1 ?�� raw water storage in the former American Store Quarry on NC 54 (site of this request) . The 20 year safe yield of the quarry is estimated at 0.5 mgd, giving OWASA a total current 20-year safe yield of 13.5 mgd (with Cane Creek Reservoir) . Because Orange County is at or near the headwaters of major drainage basins, the sub-basins from which county suppliers can draw are small. This results in potential reservoir yields that are, as best, modest. It is clear that Orange County does not have the sites with a potential to supply large amounts of water over long periods of time. Even with the Cane Creek Reservoir, the County as a whole could face a demand deficit before the year 2010. This proposal if approved, will provide approximately 3 billion gallons of storage capacity - more than five times the capacity of University Lake. In 1979, the orange County Board of Commissioners appointed the Water Resources Task Force, investing in it five charges: 1) defining water quality goals for Orange County; 2) reviewing water resources data and compiling an inventory of existing and potential reservoir sites; 3) developing, reviewing, and ranking watershed protection strategies; 4) preparing the water resources section of the County Land Use Plan; and, 5) recommending a long term water resources management plan for orange County. The Task Force Report recognized the existing quarry reservoir, but did not speak to the suitability of former quarries for water storage. Also, the report did not address the possibility of expanding the existing quarry operation to eventually connect with the quarry reservoir as is now being proposed. The protection of County water supply watersheds from point and non-point source pollutants through regulation and land use controls was a prominent recommendation of the task force and a focal point of the watershed plan which resulted. Non-point source pollution generations is a function of land use. As a watershed becomes increasingly urbanized, the activities which generate pollutants are increasingly present in the watershed. Increased impervious surface area, as seen in more developed areas, alters the relative magnitude of runoff and infiltration. This can negatively affect the water quality of streams flowing through urban areas. The petitioner states that the relocated asphalt plant would be designed and constructed with sophisticated environmental safeguards, as recommended by Camp Dresser McKee, OWASAIS watershed 15
