a � <br /> ' w <br /> Iftw/ <br /> CONDITIONS FOR N-3868-1-0 page. 2 <br /> 8. Measurements to 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. Imtial compliance with VOC emission rate and control efficiency requirem <br /> days of the test. ents shall be demonstrated by <br /> the <br /> results <br /> of the laboratory sample analysis. The results shall be submitted to the District within 60 <br /> 10. Ongoing com liance with VOC emission rate and control efficiency requirements shall be demonstrated by <br /> sampling both the influent and the effluent gas streams with a PID, PID, or other District-approved <br /> VOC detection device. <br /> I1. Samplin to demonstrate ongoing compliance shall be performed at least once per month when utilizing <br /> the rata€ytic oxidizer unit. <br /> 12. Records of the cumulative running time and the measured influent and effluent VOC concentrations shall <br /> be maintained. <br /> 13. All records shall be retained for a minimum of 2 years, and shall be made available for District <br /> inspection upon request. <br /> 14. Operation of the remediation system shall not exceed 2 years without prior District approval. <br /> 15. The oxidizer shall be equipped and operated with a gauge which indicates the temperature of the <br /> combustion chamber. A continuous recording device shall be utilized to document the combustion <br /> chamber temperature during system operation. <br /> 16. The remediation system shall not be operated unless the combustion chamber is at or above the minimum <br /> operating temperature. The system shall automatically terminate operation if the temperature drops <br /> below the minimum operating temperature. <br /> 17. The minimum operating temperature for the combustion chamber of the catalytic oxidizer shall be 600 <br /> degrees F. <br /> 18. The total VOC emission rate from the remediation system served by the catalytic oxidizer shall not <br /> exceed 14.3 pounds in any one day. <br /> 19. A minimum of two carbon canisters which are connecter) in series shall be utilized. ` <br /> 20. The carbon canisters removed from the system shall be sealed vapor tight. <br /> 21. Neither the soil ventilation rate or the effluent gas flow rate shall dxceed 250 scfm when utilizing <br /> carbon canisters. <br /> 22. The VOC concentration of the effluent gas from the remediation system served by carbon canisters shall <br /> not exceed 25 ppmv (as hexane). <br /> 23. Sampling to demonstrate ongoing compliance shall be performed at least once per week when utilizing <br /> carbon canisters. <br /> 24. The District shall be notified in writing at least 30 days prior to a change from one type of control <br /> Uuip <br /> ument to another. Only the control equipment specifically identified in this permit shall be <br /> 9/Z'd dnoa5 831UM U3-13 WdZT:TO 86, T2 130 <br />
