and dated October 20, 1995 . 2. 1. 1 Health and Safety Plan Prior to initiating any field work, a site specific health and safety plan was prepared in accordance with 29 CFR 1910. 120 . The health and safety plan provides a summary of physical - and chemical hazards at the site, names and telephone numbers of responsible individuals working on the project, and emergency instructions and directions to receive medical attention. An abbreviated version of the health and safety plan without its attachments is included as Appendix A. 2. 1. 2 Permits and Utility Clearance To perform the soil and groundwater investigation, a Well/Pump Permit was obtained from PHS/BHD . A copy of the permit is included in Appendix B . Since all drilling locations were located within the airport property boundary and off of any public road right-of-way, neither offsite access agreements nor encroachment permits were necessary, At least 48 hours prior to drilling operations, Underground Service Alert (USA) was notified to perform a routine utility clearance inspection. As an added precaution, each sampling location was dug by hand to a depth of approximately 4 feet bgs to prevent any damage to underground utilities. 2. 2 Soil and Groundwater Investigation On January 3 and 4, 1996, IT Corporation conducted an investigation of subsurface soil and groundwater using a Geoprobe Direct Penetration Technology (DPT) rig. Soil and groundwater samples were collected from two locations indicated as SB-3 and SB-4 on the Site Plan (Figure 2) . Two additional sample locations (SB- I and SB-2) were discontinued at a depth of 16 feet bgs i due to rig refusal resulting from contact with a subsurface concrete stab used to anchor the i former USTs. The sample locations and approximate extent of this underground concrete slab are shown on Figure 2. One Geoprobe sample location-(SB=3) was positionedtu investigate the-southwestern end of the SAC/2-22-96/ENG/765436 6 I
