14 September 2004 <br /> AGE-NC Project No 03-1100 <br /> Page 2 of 9 <br /> in accordance with Occupational Safety and Health Guidance Manual for Hazardous Waste Site <br /> Activities (National Institute for Occupational Safety and Health Administration, U S Coast Guard <br /> and U S Environmental Protection Agency, 1985) is on file <br /> 2 2 SOIL VAPOR EXTRACTION/OZONE SPARGE PIPING NETWORK <br /> The above-ground SVE and IOS piping network was installed on 17 August 2004 Two-inch <br /> diameter, schedule 40 PVC piping was routed from the SVE well heads to the vapor extraction unit, <br /> 3/8-inch diameter PVC tubing in appropriately sized conduits was routed from the IOS well heads <br /> to the ozone generator location The SVE and IOS piping system are illustrated on Figure 3 <br /> 23 PROPOSED SOIL VAPOR EXTRACTION AND OZONE SYSTEMS DESIGN <br /> A catalytic destruction process is proposed for the recovered hydrocarbon vapor by utilizing a direct <br /> electric heated catalytic-oxidizer soil vapor extraction system (VES), the SVE unit is somewhat <br /> portable to allow for relocation on the site as necessary Specifications of the system are illustrated <br /> in Appendix A Cost justification for a catalytic-oxidizer VES versus vapor-phase carbon and <br /> thermal oxidizer, as requested by the SJCEHD by letter dated 02 September 2004, is provided in <br /> Appendix B The aforementioned letter is provided in Appendix C <br /> An EnviroSparge ozone system is proposed to produce the gaseous ozone to be infected into the <br /> subsurface via microsparge points The"microbubbles"(approximately 50 micrometers)are forced <br /> out into the surrounding saturated soil and react with the target analytes, producing carbon dioxide <br /> and water <br /> The SVE piping network will connect the SVE wells to an electric heated catalytic oxidizer vapor <br /> extraction system (VES) via a manifold box, and the ozone-spargmg piping network will connect <br /> IOS wells directly to the ozone generator, a typical diagram of the VES system is illustrated in <br /> Appendix A The VES and IOS systems will be placed in a chain-linked, gated enclosure that <br /> encompasses the site (Figure 3) - <br /> 24 IN-SITU OZONE SPARGING PILOT TEST <br /> Following installation of the IOS system, a 24-week (6 months) IOS pilot study is proposed at the <br /> site,the results of the IOS pilot test will provide data to calculate an effective radius of influence and <br /> determine the feasibility of IOS as a remediation alternative Procedures for the IOS pilot test are <br /> presented in Section 4 3 <br /> Advanced GeoEnvironmental,Inc <br />
