Tonight presents an opportunity for the elected officials to enter into a direct dialogue with the members of the LSSC and the LOG. ~: '~~III. INTi20DIICTION OF LANDFILL SITE SEARCH COMMITTEE MEMBERS AND THE CONSIILTANTS Eddie Mann, Chair of the LSSC, introduced the committee members. Members present: Chris Derby, Walter Fairbault, Jr., Leigh Peek, Daniel Textoris, Thomas Warren, Susan Doverbarger and Dan VanderMeer. Mr. Mann also introduced consultants Leonard Joyce from Joyce Engineering and Geophysicist E. W. (Wes) Scarlett, Jr. from Bain, Palmer and Associates. IV. BRIEF DESCRIPTION OF PROCESS TO DATE Mr. Mann described the landfill search process to date. They began their process in April, 1990. The group first became familiar with the concept of a landfill and the process they would need to follow. A screening criteria, including those mandated by law, was developed. One of the criteria was that they would find a minimum of 300 acres. The consultants were then asked to apply this criteria to Orange County. From this information maps showing the potential landfill sites were developed. As a way of rating these sites a list of ranking criteria was developed where percentage values were assigned to certain criteria. This was the basis for comparing the sites. They had visited each site and held many meetings. In November, 1991 the LSSC selected four sites for further testing. In March of 1992 they selected two sites for geotechnical testing, OC3 and OC17. Site OC3 was deleted because they were told that it would not be permitted by the State. They then added OC2, OC9 and OC11 for geotechnical testing. QIIESTION: What alternatives are there for less intrusive site examination methods, such as seismic refraction. Were these considered in the process? If so, why were they not chosen? What are the advantages and disadvantages of the testing proposed by Joyce Engineering versus any alternatives? What are the advantages and disadvantages of simultaneous versus sequential testing of multiple sites? ANSWER: Mr. Joyce talked first about the purpose of the geotechnical testing. When locating a landfill there are certain site features that are absolutely essential. This includes subsurface features of the land such as depth and quantity and types of soils on a site, the depth of rock, the geology characteristics in the area, and information regarding the ground water underneath the site. These factors greatly influence the design, permitting, construction and operation of a landfill site. This would provide the necessary information to enable Joyce Engineering to do preliminary engineering evaluations as to how much life each site had and the limitations the land had in developing a landfill. This would provide the LOG the technical quantitative information so they could do a relative comparison of each site.
