Conde dual-stage 46 sparge blower <br /> Sparge well and blower controller/timer(7-channel) <br /> ' AQMD permit no. N-341.3-1-0 <br /> Status for reporting period: i <br /> The King-Buck 100 cfrn catalytic oxidizer was installed at the site in November 1995 and and began operation in January of <br /> 1996. The system currently operates without air sparging due to high influent concentrations from the vapor well field. The <br /> system operated 50%of the reporting period and removed 776 pounds of hydrocarbons at an average extraction rate of 69 cfm <br /> with dilution air. <br /> A The oxidizer influent and effluent VOC concentrations are monitored on monthly site visits using a photo ionionization detector - <br /> (PID)only per requirements. The PID readings measured this period indicate the effluent concentrations were in compliance with <br /> SJVUAPCD requirements. The influent concentrations to the oxidizer averaged 557 ppm. The system will operate on a continual <br /> schedule for the third quarter of 1996. �! <br /> I; <br /> V <br /> Operating mode: Catalytic oxidation: <br /> i <br /> TPH conc.end of period(PID,ppmv): 533 <br /> Flowrate end of period: 70 ; <br /> I <br /> HC destroyed this period(PID,lbs): 776 <br /> Soil vapor extraction system <br /> Operating hours this period: 1268 <br /> 1 <br /> Percent up time: 50% <br /> Operating hours to date: 1,852 <br /> q <br /> Air sparge-system (Not operating, influent concentrations are high) <br /> Operating hours to date: 0 <br /> S <br /> Attachments: <br /> Table 1.Soil Vapor Extraction and Treatment System Influent Data <br /> Table 2.
