Condensate Recovery System, Collection of Trap Organics APÉNDICE A MÉTODO 25C DEL 40 CRF PARTE 60 METHOD 25C- DETERMINATION OF NONMETHANE ORGANIC COMPOUNDS (NMOC) IN MSW LANDFILL GASES 1. Applicability and Principle 1.1 Applicability. This method is applicable to the sampling and measurement of nonmethane organic compounds (NMOC) as carbon in MSW landfill gases. 1.2 Principle. A sample probe that has been perforated at one end is driven or augered to a depth of 1.0 meter below the bottom of the landfill cover. A sample of the landfill gas is extracted with an evacuated cylinder. The NMOC content of the gas is determined by injecting a portion of the gas into a gas chromatographic column to separate the NMOC from carbon monoxide (CO), carbon dioxide (CO₂), and methane (CH4); the NMOC are oxidized to CO₂, reduced to CH₄, and measured by a flame ionization detector (FID). In this manner, the variable response of the FID associated with different types of organics is eliminated. 2. Apparatus 2.1 Sample Probe. Stainless steel, with the bottom third perforated. The sample probe shall be capped at the bottom and shall have a threaded cap with a sampling attachment at the top. The sample probe shall be long enough to go through and extend no less than 1.0 meter below the landfill cover. If the sample probe is to be driven into the landfill, the bottom cap should be designed to facilitate driving the probe into the landfill. 2.2 Sampling Train. 2.2.1 Rotameter with Flow Control Valve. Capable of measuring a sample flow rate of 500 ml/min or less (30.5 + 3.1 m3/min). The control valve shall be made of stainless steel. 2.2.2 Sampling Valve. Stainless steel. I 2.2.3 Pressure Gauge. U-tube mercury manometer, or equivalent, capable of measuring pressure to within 1 mm Hg in the range of 0 to 1,100 mm Hg. 2.2.4 Sample Tank. Stainless steel or aluminum cylinder, with a minimum volume of 4 liters and equipped with a stainless steel sample tank valve. 2.3 Vacuum Pump. Capable of evacuating to an absolute pressure of 10 mm Hg. 2.4 Purging Pump. Portable, explosion proof, and suitable for sampling NMOC. 2.5 Pilot Probe Procedure. The following are needed only if the tester chooses to use the procedure described in section 4.2.1. 2.5.1 Pilot Probe. Tubing of sufficient strength to withstand being driven into the landfill by a post driver and an outside diameter of at least 6.0 millimeters smaller than the sample probe. The pilot probe shall be capped on both ends and long enough to go through the landfill cover and extend no less than 1.0 meter into the landfill. 2.5.2 Post Driver and Compressor. Capable of driving the pilot probe and the sampling probe into the landfill. 2.6 Auger Procedure. The following are needed only if the tester chooses to use the procedure described in section 4.2.2. 2.6.1 Auger. Capable of drilling through the landfill cover and to a depth of no less than 0.9 meters into the landfill. 2.6.2 Pea Gravel. 2.6.3 Bentonite. 2.7 NMOC Analyzer, Barometer, Thermometer, and Syringes. Same as in sections 2.3, 2.4.1, 2.4.2, 2.4.4, respectively, of Method 25. 2 3. Reagents 3.1 NMOC Analysis. Same as in Method 25, section 3.2. 3.2 Calibration. Same as in Method 25, section 3.4, except omit section 3.4.3. 4. Procedure 4.1 Sample Tank Evacuation and Leak Check. Conduct the sample tank evacuation and leak check either in the laboratory or the field. Connect the pressure gauge and sampling valve to the sample tank. Evacuate the sample tank to 10 mm Hg absolute pressure or less. Close the sampling valve, and allow the tank to sit for 60 minutes. The tank is acceptable if no change is noted. Include the results of the leak check in the test report. 4.2 Sample Probe Installation. The tester may use the procedure in sections 4.2.1 or 4.2.2. CAUTION: Since this method is complex, only experienced personnel should perform this test. LFG contains methane, therefore explosive mixtures may exist on or near the landfill. It is advisable to take appropriate safety precautions when testing landfills, such as refraining from smoking and installing explosion-proof equipment. 4.2.1 Pilot Probe Procedure. Use the post driver to drive the pilot probe at least 1.0 meter below the landfill cover. Alternative procedures to drive the probe into the landfill may be used subject to the approval of the Administrator. Remove the pilot probe and drive the sample probe into the hole left by the pilot probe. The sample probe shall extend not less than 1.0 meter below the landfill cover and shall protrude about 0.3 meters above the landfill cover. Seal around the sampling probe with bentonite and cap the sampling probe with the sampling probe cap. 4.2.2 Auger Procedure. Use an auger to drill a hole through the landfill cover and to at 3 Sampling Valve Vent Flow Control Valve Purge Pump Rolameler Sample Probe Cap Sampling Probe 940074DRTP Landfill Cover Surface Figure 1. Schematic of sampling probe purging system. least 1.0 meter below the landfill cover. Place the sample probe in the hole and backfill with pea gravel to a level 0.6 meters from the surface. The sample probe shall protrude at least 0.3 meters above the landfill cover. Seal the remaining area around the probe with bentonite. Allow 24 hours for the landfill gases to equilibrate inside the augered probe before sampling. 4.3 Sample Train Assembly. Prepare the sample by evacuating and filling the sample tank with helium three times. After the third evacuation, charge the sample tank with helium to a pressure of approximately 325 mm Hg. Record the pressure, the ambient temperature, and the barometric pressure. Assemble the sampling probe purging system as shown in figure 1. 4 Sampling Vacuum Gauge Valve - Flow Control X Valve X Quick Disconnect Rolam el er X Sample Tank Valve Sample Probe Cap Sampling Probe Sample Tank Landfill Cover Surface 940075DRTP Figure 2. Schematic of sampling train. 4.4 Sampling Procedure. Open the sampling valve and use the purge pump and the flow control valve to evacuate at least two sample probe volumes from the system at a flow rate of 500 ml/min or less (30.5 + 3.1 m3/min). Close the sampling valve and replace the purge pump with the sample tank apparatus as shown in figure 2. Open the sampling valve and the sample tank valves and, using the flow control valve, sample at a flow rate of 500 ml/min or less (30.5 ± 3.1 m³/min) until the sample tank gauge pressure is zero. Disconnect the sampling tank apparatus and use the carrier gas bypass valve to pressurize the sample cylinder to approximately 1,060 mm Hg absolute pressure with helium and record the final pressure. Alternatively, the sample tank may be pressurized in the lab. If not analyzing for N2, the sample cylinder may be pressurized with zero air. Use Method 3C to determine the percent N₂ in the sample. Presence of N₂ indicates infiltration of ambient air into the gas sample. The landfill sample is 5 acceptable if the concentration of N₂ is less than 20 percent. 4.5 Analysis. The oxidation, reduction, and measurement of NMOC is similar to Method 25. Before putting the NMOC analyzer into routine operation, conduct an initial performance test. Start the analyzer, and perform all the necessary functions to put the analyzer into proper working order. Conduct the performance test according to the procedures established in section 5.1. Once the performance test has been successfully completed and the NMOC calibration response factor has been determined, proceed with sample analysis as follows: 4.5.1 Daily Operations and Calibration Checks. Before and immediately after the analysis of each set of samples or on a daily basis (whichever occurs first), conduct a calibration test according to the procedures established in section 5.2. If the criteria of the daily calibration test cannot be met, repeat the NMOC analyzer performance test (section 5.1) before proceeding. 4.5.2 Operating Conditions. Same as in Method 25, section 4.4.2. 4.5.3 Analysis of Sample Tank. Purge the sample loop with sample, and then inject the sample. Under the specified operating conditions, the CO₂ in the sample will elute in approximately 100 seconds. As soon as the detector response returns to baseline following the CO₂ peak, switch the carrier gas flow to backflush, and raise the column oven temperature to 195 °C as rapidly as possible. A rate of 30 °C/min has been shown to be adequate. Record the value obtained for any measured NMOC. Return the column oven temperature to 85 °C in preparation for the next analysis. Analyze each sample in triplicate, and report the average as Ctm. 4.6 Audit Samples. Same as in Method 25, section 4.5. 4.7 Deactivation of Sample Probe Holes. Once sampling has taken place, either plug the 6 sampling probes with a cap or remove the probes and refill the hole with cover material. 5. Calibration and Operational Checks Maintain a record of performance of each item. 5.1 Initial NMOC Analyzer Performance Test. Same as in Method 25, section 5.2, except omit the linearity checks for CO₂ standards. 5.2 NMOC Analyzer Daily Calibration. NMOC response factors, same as in Method 25, section 5.3.2. 6. Calculations All equations are written using absolute pressure; absolute pressures are determined by adding the measured barometric pressure to the measured gauge of manometer pressure. 6.1 Nomenclature.
