* Conditions for N-8569-2-0 (continued) Page 2 of 4 9. The engine exhaust stack shall have a minimum height of'40 feet above the ground, and a maximum inside diameter of 20 inches at the point where the exhaust gas is emitted to the atmosphere. [District Rules 2201 and 4 102 10. The concentration of sulfur compounds in the landfill gas entering this stationary source shall not exceed 150 ppmvd as H2S. [District Rule 22011 11, The landfill gas now rate to this stationary source shall not exceed 2,084 scf/min. [District Rule 22011 12. This engine shall be fired exclusively with landfill gas. [District Rule 22011 13. Emissions from this landfill gas-fired engine shall not exceed 0.15 g-NOx/bhp-hr, 0.05 g-PMfO/bhp-hr, I.8 g-CO/bhp- hr, 0.20 g-VOC/bhp-hr, and IS ppmvd NI 13 at 15% 02. [District Rules 2201 and 4102 14, Either the non -methane organic compound (NMOC) emissions from this landfill gas-fired engine shall not exceed 20 ppmvd (as hexane) at 3% 02 or the NMOC destruction efficiency shall be at least 98%. [District Rule 2201 and 40 CFR 60.752(b)(2)(iii)(13)] 15. CO emissions from this stationary source shall not exceed 199,999 pounds in any rolling 12 -consecutive -month period [District Rule 2201] 16. VOC emissions from this stationary source shall not exceed 19,999 pounds in any rolling 12 -consecutive -month period. [District Rule 22011 17, The permittee shall monitor and record the stack concentration of NOx, CO, and 02 concurrently at least once every calendar month (in which a source test is not performed) using a portable emission monitor that meets District specifications. [In -stack 02 monitors may be allowed il'approved by the APCO.] Monitoring shall not be required if the engine is not in operation, i.e. the engine need not be started solely to perform monitoring. Monitoring shall be performed within five days of restarting the engine unless monitoring has been performed within the last month. AML Records must be maintained of the dates of non -operation to validate extended monitoring frequencies. [District Rules 4 70 1 and 4702] 18. The permittee shall monitor and record the stack concentration of NH3 at least once every calendar quarter (in which a source test is not performed). NH3 monitoring shall be conducted utilizing Draeger tubes or a District approved equivalent method. Monitoring shall not be required if the engine is not in operation, i.e. the engine need not be started solely to perform monitoring. Monitoring shall be performed within five days of restarting the engine unless monitoring has been performed within the last month. Records must be maintained of the dates of non -operation to validate extended monitoring frequencies. [District Rule 22011 I9. If either the NOx or CO concentrations corrected to 15% 02, as measured by the portable analyzer, exceed the allowable emission concentration, the permittee shall retuni the emissions to within the acceptable range as soon as possible, but no longer than 24 hours after detection. If the portable analyzer readings continue to exceed the allowable emissions concentration after 8 hours, the permittee shall notify the District within the following l hour, and conduct a certified source test within 60 days of the first exceedance In lieu of conducting a source test, the permittee may stipulate a violation has occurred, subject to enforcement action. The permittee must then correct the violation, show compliance has been re-established, and resume monitoring procedures If the deviations are the result of a qualifying breakdown condition pursuant to Rule 1100, the permittee may fully comply with Rule 1 100 in lieu of performing the notification and testing required by this condition. [District Rules 4701 and 4702] 20. All alternate monitoring parameter emission readings shall be taken with the unit operating either at conditions representative of normal operations or conditions specified in the permit -to -operate, The analyzer shall be calibrated, maintained, and operated in accordance with the manufacturer's specifications and recommendations or a protocol approved by the APCO. Emission readings taken shall be averaged over a 15 consecutive -minute period by either taking a cumulative 15 consecutive -minute sample reading or by taking at least five (5) readings, evenly spaced out over the 15 consecutive -minute period. [District Rules 4701 and 4702] 21 . The permittee shall maintain records of. (I) the date and time of NOx, CO, and 02 measurements, (2) the 02 concentration in percent and the measured NOx and CO concentrations corrected to 15% 02, (3) make and model of exhaust gas analyzer, (4) exhaust gas analyzer calibration records, and (5) a description of any corrective action taken to maintain the ern issions within the acceptable range.
