Historical soil analytical results are included as Attachment B. To complete the proposed scope of work, <br />GHD will perform the tasks below. <br /> <br />2.1 Permits <br />GHD will obtain necessary soil boring permits as required from SJCEHD. <br /> <br />2.2 Site Health and Safety Plan <br />GHD will prepare a site safety plan to inform site workers of known hazards and to provide health and <br />safety guidance. The plan will be kept onsite at all times during field activities and signed by all site <br />workers and visitors. <br /> <br />2.3 Underground Utility Location <br />GHD will notify Underground Service Alert (USA) at least 48 hours prior to field activities to clear the soil <br />boring locations with public utility companies. Additionally, GHD will hire a private utility locator to help <br />identify all subsurface lines prior to beginning work activities. Soil boring locations may be modified based <br />on the results of the private utility locate. <br /> <br />2.4 Soil Borings <br />Five borings (B-1 through B-5) will be advanced at the approximate locations shown on Figure 2. The <br />borings will be advanced using a 3-inch diameter hand auger to approximately 6 fbg. Soil encountered in <br />each soil boring will be screened using a photo-ionization detector and logged using American Society for <br />Testing and Materials (ASTM) standard D2488. Soil samples for laboratory analysis will be collected in 6- <br />inch long, 2-inch diameter brass or stainless steel sleeves at approximately 4.5 and 6 fbg using a slide <br />hammer. Only one sample will be collected from boring B-5 at ? fbg. Soil samples submitted for chemical <br />analyses will be capped with Teflon, labeled, entered onto a chain of custody form, packed on ice, and <br />sent to Eurofins Lancaster Laboratories (Lancaster) in Lancaster, Pennsylvania. <br /> <br />2.5 Laboratory Analyses <br />Soil samples from borings B-1 through B-3 will be analyzed for the following analyses: <br />Total petroleum hydrocarbons as gasoline (TPHg) by EPA Method 8015M <br />Benzene and ethylbenzene EPA Method 8260B <br />Naphthalene by EPA Method 8270 (detection limit less than 10 milligrams per kilogram) <br />Soil samples from boring B-4 will be analyzed for the following analyses: <br />Oil and grease (TOG) by EPA Method 1664A <br />TPH as diesel (TPHd), TPHd with 10-gram silica gel cleanup, and TPHg by EPA Method 8015M <br />632277D-RPT 24-WORK PLAN ADDENDUM docx SECOND ADDENDUM 3
