CA '94520 <br /> EQUIPMENT DESCRIPTION: <br /> SOIL VAPOR EXTRACTION AND REMEDIATION SYSTEM SERVED BY AN ALTON r'ROSCIENCE (MODEL#V0150) <br /> CATALYTIC OXIDATION SYSTEM FOLLOWED BY AN AQUATEC(MODEL#MX500-Y).CARD01N ADSORPTION SYSTEM. <br /> CONDITIONS <br /> 1. No air Ggtl �nir�F .�.�. <br /> to alit shall be released into the atmosphere which causes a public nuisance. <br /> 2. No air contarnin�nt shall be discharged into the atmosphere for a period or periods aggregatin� more than <br /> three minutes in,l,any one hour which is dark or darker than R.ingelmann.1 car equivalent to 20% opacity. <br /> I' <br /> 3. The soil remediation project shall lac mainudned in proper operating condition at all times. <br /> 4, Either the VOC control efficiency shall not be less than 95 7b, or the total VOC emission rate shall not <br /> exceed 2 pounds'in any one day. <br /> 5. Sampling parts aduate for extraction of grab samples, measurement of gas flaw rate, and use of an FID, <br /> PID, or other District-approved VOC detection device shall be providc+d for both the influent and the <br /> effluent gas streams. <br /> 1 <br /> 6. Laboratory samples shall be taken at the initial inspection, under the supervision of the APCD <br /> inspector. Samples shall be taken from }cath the influent and the effluent gas stream sampling ports. <br /> h <br /> 7. Laboratory sarnl les shall be analy2ed for TPH and RTEX. <br /> 8- Measurements too determine the influent and the effluent gas flow rates shall be taken at the initial <br /> inspection. Flow rate calculations shall be submitted to the District along with the laboratory sample <br /> analysis results. <br /> 9. initial compliance with VOC emission rate and control efficiency requirements shall be- demonstrated by <br /> the results of the'laboratory sample analysis. The results shall be submitted to the District within <br /> 60 days of the test. <br /> �k <br /> 10. Ongoing euroliaise with VOC emission rate and control efficiency requirements shall be demonstrated by <br /> h <br /> sampling botthe influent and the effluent gas streams with a FID, PID, or other District-approved <br /> VOC detection(device. <br /> 11. SaEnpl.ing to demonstrate ongoing compliance shall be performed at lust once per month when utilizing <br /> the catalytic oxidizer unit. <br /> 12, Records of the cumulative running time and the measured influent. and effluent VOC concentrations shall <br /> be maintained. ,I <br /> 13. All records shall be retained for a minimum of 2 years, and shall be made available for District <br /> inspeotiun upon'request. <br /> I <br /> CONDITIONS C:ONITIN f.-l`E ON NEXT PAGE <br />
