lgas will be fed to the catalytic incinerator for abatement by an electrically driven pumping unit. The extracted air stream will first enter a pre-heat section that contains a i gas burner. The pre-heated air stream will then enter a I dual catalytic bed where oxidation of the hydrocarbon vapors will occur. Natural gas or propane will be used as fuel for the catalytic incinerator. A 230 volt, single phase electrical power source will be brought onto the site to provide electrical service to the system equipment. The catalytic incinerator, pumping unit and the accumulator/ 1 water knockout device will be enclosed by chain link fencing 1 for security purposes. The specifications for the accumulator/water knockout device and the equipment layout are given in Details A-7 and A-8 , respectively. SOIL VACUUM EXTRACTION PROGRAM The soil vacuum extraction program will proceed in four tasks. The tasks and associated time to complete include: 1) Regulatory Authorization and Permitting, 30 to 60 days; 2) System Installation, 21 days; 3) Equipment Installation, 10 days; and 4) Operation and Maintenance, 6 to 12 months. REGULATORY AUTHORIZATION AND PERMITTING Hydrocarbons will be removed from the soil during the vacuum extraction process. If the concentration of hydrocarbons in the extracted air stream exceeds emission levels established by the county regulatory agency, the hydrocarbons will be abated before the air stream is disbursed to the atmosphere. Although the level of hydrocarbons emitted will be within regulatory standards, authorization from the county regulatory agency is required to ensure public safety. EVAX Technologies, Inc. will obtain the necessary air permits from the San Joaquin Air Pollution Control District. SYSTEM INSTALLATION Field Installation ' Trenches will be dug and pipes laid according to the system design. The temporary vacuum extraction probes will be driven pneumatically into the soil at the locations and to the depths specified in the design. The probes will be connected to the piping and the piping will be connected to the manifold. The groundwater monitoring wells will be connected by pipes to the manifold. The manifold will then be piped to the equipment area.
