ATC Associates Inc, <br /> 1117 Lone PellaAvenue, Sante 201 <br /> Modesto, California 95351 <br /> 209-579-2221 <br /> A S S 0 C I A T E S INC , <br /> Fax: 209-579-2225 <br /> be installed over each vapor extraction well (Figure 9). For the sake of efficiency and to mirnimize <br /> disruption to the site tenant, trenching activities will not be initiated until the planned ozone pilot <br /> testing has been completed and a determination regarding installation of an ozone injection system <br /> for groundwater remediation has been made. ATC expects that ozone related piping and control <br /> equipment can be collocated in the soil vapor extraction trench and compound, respectively. An <br /> above ground wellhead manifold will be constructed within the compound for airflow control from <br /> the vapor extraction wells and will include a sampling port for monitoring purposes (Figures 10 <br /> and 11). <br /> Equipment operation will require the installation of an electrical power source and meter base. Site <br /> system requirements will likely include a 230V, three-phase 100-amp power source. The thermal <br /> unit will also be supplied with either propane or natural gas as the supplemental fuel source. A <br /> NEMA 4, UL Listed Control Panel will be located at the compound (Figures 12 and 13). <br /> 9.2.3 I2enrediation System Construction <br /> Upon review and approval of the remediation system design plans and specifications by the <br /> SJCEHD, ATC will complete the following tasks. <br /> 9.2A Permits and Inspections <br /> An Authority to Construct and Permit to Operate application will be completed and submitted to <br /> the SJVAPCD to allow for construction and installation of the proposed system . The application <br /> will include site-specific historical information, vapor extraction specifications, and analytical <br /> results. A complete set of plans will be submitted to the City of Stockton Building, Planning, and <br /> Fire Departments for review, comment, and approval prior to construction and installation of the <br /> system. <br /> Following approval of the design plans and specifications, obtaining City Building, Planning, and <br /> Fite Department permits, and SJVAPCD air permit to construct, the remediation system will be <br /> installed in accordance with the approved Plans and Specifications. Construction will include <br /> completion of wellhead piping connections; pressure testing of lines; installation of remediation <br /> compounding fencing; connection of electrical service and installation; and plumbing of all process <br /> equipment related to the extraction system. <br /> 9.2.5 System Startup and Operation <br /> After completion of installation, operation of the proposed system will be initiated in compliance <br /> with applicable regulatory agencies. Startup procedures will include monitoring, maintenance, and <br /> sampling within the first five clays of operation, Operation and maintenance of the system typically <br /> includes three site inspections for the first week of operation , and site visits once every week for the <br /> first month. After the first month of operation, site visits will be typically performed once every <br /> two to four weeks, or as needed over the operating life of the remediation system.
