TABLE 1 <br /> Soil Vapor Extraction = Operational Data <br /> Chevron Facility #92033 = Stockton Charter Way Commingled Plume Site <br /> 508 W Dr. Martin Luther King Jr. Blvd , Stockton , California <br /> SVE System Status Hour Period Cumulative Applied Dilution Air Well Field Flow Rate Oxidizer FID Reading (Hexane) <br /> (On/OM Total Uptime Uptime Vacuum Valve <br /> Date Notes ( ffJ Meter Runtime p OZ COZ Influent Combustion Effluent Temp Influent Effluent <br /> Arrival Depart Reading (%) (%) (" Hg ) (% Open) I (scfm) (scfm) (scfm ) (°F) (ppm) (ppm) <br /> Notes (continued): <br /> a = SVE System operated for initial source test vapor sampling with SJVAPCD personnel . Air sparge system not operational during source test. <br /> b = SVE System found shut down on 4/5 due to low temperature alarm and was restarted . Total Runtime was back-calculated from 4/9 Hour Meter Reading. <br /> c = Hour meter on SVE System was reset. Period and Cumulative Uptimes were calculated using the last SVE actual hour meter reading of 147 and AS reading of 141 . <br /> d = Based on remote monitoring data log , the system shutdown due to high oxidizer temperature alarm . Hour meter reading was back calculated. <br /> e = Based on remote monitoring data log, the system shutdown due to low vacuum alarm . Hour meter reading was back calculated. <br /> f = Based on remote monitoring data log, the system shutdown due to low oxidizer temperature alarm . System was kept shut down for troubleshooting . <br /> Equation : <br /> Effluent Flow Rate = Influent Flow Rate + Combustion Flow Rate [max 92 cfm] <br /> Influent Flow Rate = Main Blower Flow Rate <br /> SJVAPCD Authority-to-Construct/Permit-to-Operate Requirements (N-8790-1 -0): <br /> 1 . Minimum operating temperature at or above 1 ,400°F in thermal mode <br /> Period Uptime Equation: <br /> % = If Period Uptime < 100% AND System On , then 100.0% . If Period Uptime > 100% , then 100% . Everything else is as it is. <br /> 92033 Remediation Workbook.xlsx 2 of 2 Stantec <br />
