conditions for N-8569-2-0 (continued) Page 3 of 4
<br />22, The sulfur compound content of the landfill gas entering this stationary source shall be monitored and recorded
<br />monthly, After four consecutive monthly tests show compliance, the monitoring frequency may be reduced to once
<br />every calendar quarter, If quarterly monitoring shows an exceedance of the limit, then monthly monitoring shall
<br />resume and continue until four consecutive months of monitoring show compliance with the limit. Once compliance
<br />with the limit is shown for four consecutive months, then the monitoring frequency may return to quarterly.
<br />Monitoring shall not be required in any month during which neither the engines nor the flare operate. Records of
<br />monitoring results shall he maintained as required elsewhere in this permit. [District Rule 2201 ]
<br />23. Monitoring of the landfill gas sulfur compound content shall be performed using Draeger tubes or an alternative
<br />method approved in writing by the District, [District Rule 22011
<br />24. Source testing to measure landfill gas-eorlibustion NOx, CO, NH3, and VOC emissions, and NMOC emissions and
<br />destruction efficiency, from this unit shall be conducted within 90 days of initial start-up, [District Rules 4701 and
<br />4702 and 40 CFR 60.752(b)(2)(iii)(B)]
<br />25. Source testing to measure landfill gas -combustion NOx, CO, NH3, and VOC emissions from this unit shall be
<br />conducted at least once every 12 months. After demonstrating compliance on two consecutive annual source tests, the
<br />unit shall be tested not less than once every 24 months. If the result of the 24 -month source test demonstrates that the
<br />unit does not meet the applicable emission limits, the source testing frequency, shall revert to at least once every 12
<br />months. [District Rules 2201, 4701, and 47021
<br />26_ Emissions source testing shall be conducted with the engine operating either at conditions representative of' normal
<br />operations or conditions specified in the Permit to Operate. [District Rules 4701 and 4702]
<br />27. Source testing shall be conducted using the methods and procedures approved by the District. The District must he
<br />notified at least 30 days prior to any compliance source test, and a source test plan must be submitted for approval at
<br />least 15 days prior to testing. [District Rule 108 1]
<br />8 The results of each source test shall be submitted to the District within 60 days thereafter. [District Rule 108 11
<br />29. For emissions source testing, the arithmetic average of three 30 -consecutive -minute test runs shall apply. If two of
<br />three runs are above an applicable limit, the test cannot be used to demonstrate compliance with an applicable lirnit.
<br />VOC emissions shall be reported both as methane and as hexane. NOx and CO concentrations shall be reported in
<br />ppmv, corrected to 15% oxygen. VOC concentrations shall be reported in ppmv, corrected to 15% oxygen as methane
<br />and corrected to 3% oxygen as hexane. [District Rules 4701 and 4702 and 40 CFR 60.752(b)(2)(iii)(B)]
<br />30. The following test methods shall be used: NOx (ppmv) - EPA Method 7E or ARB Method 100, CO (ppmv) - EPA
<br />Method 10 or ARB Method 100, stack gas oxygen - EPA Method 3 or 3A or ARB Method 100, VOC (ppmv) - EPA
<br />'.Method 18, 25A or 25B, or ARB Method 100, and WOC (ppmv) - EPA Method 18, 25, 25A, or 25C. [District Rules
<br />1081, 470': , and 4702, and 40 CFR 60.754(d)]
<br />31, The permittee shall maintain an engine operating log to demonstrate compliance. The engine operating log shall
<br />include, on a monthly basis, the following information: total hours of operation, type of fuel used, maintenance or
<br />modifications performed, monitoring data, compliance source test results, and any other information necessary to
<br />demonstrate compliance, [District Rules 4701 and 4702]
<br />32 The permittee shall update the I&M plan for this engine prior to any planned change in operation. The permittee must
<br />notify the District no later than seven days after changing the T&M plan and must submit an updated I&M plan to the
<br />APCO for approval no later than 14 days after the change. The date and time of the change to the 1&M plan shall be
<br />recorded in the engine's operating log. For modifications, the revised I&M plan shall be submitted to and approved by
<br />the APCO prior to issuance of the Permit to Operate. The permittee may request a change to the I&M plan at any
<br />time, [District Rule 4702]
<br />33. Permittee shall maintain records of actual gross electrical output from this engine, in kW -hr. [District Rule 2201 ]
<br />34. Permittee shall maintain records of actual VOC and CO emissions from this LFG-fired engine. Emissions shall be
<br />calculated as follows: (actual gross electrical output, in kW -hr) x (1.341 bhp/kW) x (emission factor calculated from
<br />10 most recent source test data for that pollutant, g/bhp-hr) = (453.6 g/lb) _ (0.96). [District Rule 2201 ]
<br />35. Permittee shall maintain records of actual VOC and CO emissions from this stationary source. Records for comparison
<br />with the annual VOC and CO emission limit shall be updated at least once each calendar month. [District Rule 22011
