11 <br />'°"' Chair Carey indicated that the next issue for the Board of County <br />`Commissioners to decide is the type of testing and approval of that testing. <br />He asked if they would do fewer borings if they did the geophysical work <br />first. Mr. Joyce noted that they proposed bore holes and test pits, not the <br />geophysical work. Mr. Scarlett stated that plans to test these four sites is <br />the minimum level of effort that will give sufficient information to use in <br />a decision-making process. All the test pits and bore holes will be spread <br />widely on the acreage. The holes per acre is a big ratio of acreage per <br />single bore hole. The bore holes are so spread out and all in specific areas <br />which are targeted to soil changes and things like that from maps that already <br />exist. This level of effort is nowhere near what happens when a site is being <br />characterized as a site to engineer for a landfill. A tremendous amount of <br />work must be done at that time. At that point they can significantly reduce <br />the bore holes and trenches by using geophysical techniques. Geophysics are <br />brought in when characterizing a single site to engineer it for a landfill. <br />Chair Carey asked if bore holes and geophysical testing would <br />increase the reliability of the information enough to preclude the necessity <br />of the trenches. Mr. Joyce stated that geophysical work in combination with <br />bore hole testing would increase the reliability of the data but would not <br />eliminate the need for test pits. They would not use. any less holes because <br />they are already using the minimum amount of holes now to characterize a site. <br />One of the reasons for the test pits is to remove soil materials in sufficient <br />quantities to take to a laboratory and do an analysis on the soil so they <br />could determine the properties of the soil. <br />Mr. Fairbault stated that they have worked very hard on the process <br />of siting a landfill. He noted that he will be glad to give them a report on <br />his reasons for the selection of these four potential sites. <br />With no further comments, Chair Carey adjourned the meeting at <br />10:30. The next regular meeting will be held on October 5, 1992 at 7:30 in <br />the Courtroom at the Old Courthouse in Hillsborough, North Carolina. <br />Moses Carey, Jr., Chair <br />Beverly A.
