Startup procedures willinclude monitoring, <br /> maintenance and sampling within the first 5 days of operation. Operation and maintenance of the <br /> systems typically includes three site inspections:for the first week of operation, and site visits once <br /> every week for the first month. After the first month ofoperation, site visits will be typically performed <br /> once every 2 weeks, or as needed over the operating life of the remediation systems. Modifications to <br /> this typical schedule will be made if additional requirements are specified by the SJVUAPCD in the <br /> Authority to Construct/Permit to Operate for this site. Routine maintenance:of the VES and AS <br /> system will be performed during these site visits and as needed. <br /> Site inspections will typically include monitoring and adjustment of system parameters to optimize VES' <br /> and groundwater AS system efficiency, periodic sampling and field monitoring of influent and effluent <br /> as required by the SJ VUAPCD, and other periodic maintenance to promote continued operation of the <br /> remediation equipment. Parameters to be monitored and adjusted in the field will include vapor <br /> extraction flow rates, air injection flowrates, induced vacuum responses at onsite wells if applicable, <br /> and hydrocarbon vapor concentrations with an organic vapor monitor approved by the SJVUAPCD. <br /> Monitoring and sampling of existing groundwater wells and selected vapor extraction wells will <br /> continue on a quarterly basis. <br /> 6.5.2 Systems Sampling <br /> Typical STVUAPCD guidelines require that during the startup phase of the off-gas abatement unit, <br /> influent and effluent air samples to the VES be collected to evaluate destruction efficiency of the unit. <br /> To demonstrate compliance with SJVCTAPCD regulations,the VES will likely be sampled at least once <br /> during the first week of operation, and once per month for the life of the remediation system, With the <br /> exception of influent and effluent air samples collected and analyzed as detailed above, during the first' <br /> 2 days of operation and later on a;biweekly and monthly basis, all other sampling of the VES will be <br /> Wtt62574.01tCAP repoct.doe 12 <br />
