[District NSR Rule] 8. operation of the soil remediation system shall not exceed five years without prior District approval. [District Rule 4102.] 9. The total VOC emission rate from the soil remediation system served by the thermal/catalytic oxidizer shall not exceed 20.4 pounds in any one day. [District NSR Rule] 10, When VOC emissions are controlled by the thermal oxidizer, the operating temperature for the combustion chamber shall be maintained at or above 1,400 degrees F. [District NSR Rule] 11. All records shall be retained for a minimum of 2 years, and shall be made available for Astrid itspection upon request. [District Rule 10701 12. Records of the cumulative running time and the measured influent and effluent VOC concentrations Shall be tnaitltained. [District Rule 10'10] 13. sampling to demonstrate mgoing compliance shall be performed at least once per month. [District Rule 108 1] 14, Ongoing compliance with VOC emission rate and control efficiency requirements shall be demonstrated by sampling both the influent and the effluent gas streams with an FID, PID, or other District-approved VOC detection device. [District Rule 10811 15. Initial compliance with VOC emission rate and control efficiency shall be demonstrated for each mode of operation by the results of the laboratory analysis. The results shall be submitted to the Distxiot within 60 dsys of the test. [District Rule 10811 6. Measurements to determine the influent and the effluent gas flow rates shall be taken at the initial inspection. Flow rate calculations shall be submitted to the District with the laboratory sample analysis results. [District Rule 10811 17. Laboratory samples shall be analyzed for TPH and BTEX. [District Rule 10811 18. Sampling ports adequate for extraction of grab samples, measurement of gas flow rate, and use of an FID, PID or other District-approved VOC detection device shall be provided for both the influent and effluent gas streams. [District Rale 108 11 19. Laboratory samples shall be taken at the initial inspection, under the supervision of the APCD Inspector. Samples shall be taken from both the influent and the effluent gas stream sampling ports. [District Ririe 10811 20. Either the VOC control efficiency shall not be less than 95%, or the total VOC emissions rate shall not exceed 2 pounds in any one day. [District NSR Rule] 21. Tkze soil remediation system shill be maintained in proper operafing condition at all tides. [District NSR Rine] 22. No air contaminant shall be released into the atmosphere which causes a public nuisance. (District Rule 41021 23, No air contaminant shall be discharged into the atmosphere for a period or periods aggregating more than three minutes in any one hour which is as dark as, or darker than, Ringelmann 1 or 20% opacity.
