<br /> inAnt concontrationa will be recorded for each veal to pe:nit
<br /> :e040r;;mont of the affectivenean of the system and the decay of
<br /> contaminant concentrations over timo, It is anticipated that
<br /> emission dischargo u,lmplo analynin for airborne lead will be
<br /> required by SdCAPCD. Such e:ampinc, as required, will be col-
<br /> lected and delivered to a certified .laboratory for analyesiv..
<br /> After the VETS is brought on line, the aysto n will be nsonitored
<br /> and sampled to determine the eysterj'a effectiveness and overall
<br /> efficiency. The propocad monitoring and sampling schadule is an
<br /> _ followa (schedule and sampling requirement* may be modified by
<br /> SJCAPCD requiramenttr):
<br /> Week 1 daily monitoring with vapor sample collaction
<br /> and analysis (5 days)
<br /> Weeks 2-4 system adjustment and sample collection on
<br /> Monday, Wednesday, and Fr#day
<br /> Weeks 5-26 one day per week of system adjustment and
<br /> sample collection.
<br /> As part of the monitoring and sample schedule, total and indi-
<br /> vidual yell discharges, individual well and total discharge of
<br /> eontaminante to the VCP and CAR for treatment, and total emi.aion
<br /> concentrations from the VETS (expected to be sego) will be
<br /> logged.
<br /> 3.4 TASK IV - SYSTEM OPERATION AND MAINTENANCE
<br /> As part of the VETS operation EA will maintain and operate the
<br /> vapor treatment equipment, the plumbing system and all monitoring
<br /> x equipment. Additionally, the logo of vapor flow raters, vapor
