ively emit landfill gas to the atmosphere via vent pipes. ( évacuation ) zone-average surface methane concentration means the average of all methane concentrations recorded within a specified zone of 4500 m 2 . ( concentration moyenne de méthane en surface par zone ) EPA Method 21 adaptations — paragraph 13 (1)(a) (2) For the purposes of paragraph 13 (1)(a), with regards to EPA Method 21, (a) section 8.3.1 is to be read without regard to the fifth sentence of that section; and (b) the reference to “an increased meter reading” in that section is to be read as a reference to “a reading of 200 ppmv of methane or more”. EPA Method 21 adaptations — paragraph 19 (1)(a) (3) For the purposes of paragraph 19 (1)(a), with regards to EPA Method 21, (a) the instrument detector referred to in section 6.1 must respond to methane; (b) the instrument referred to in section 6.2 must be capable of measuring 500 ppmv of methane; (c) the scale of the instrument meter referred to in section 6.3 must be readable to ±2.5 % of 500 ppmv of methane; (d) the reference to “VOC” in section 7.1.1 is to be read as a reference to “methane”; (e) the references to “calibration gas” and “the applicable leak definition specified in the regulation” in section 7.1.2 are to be read as references to “500 ppmv of methane”; (f) in section 7.2, the requirement to have cylinder calibration gas mixtures analyzed and certified is to be read as a requirement to analyze and certify 500 ppmv of methane; (g) the reference to “calibration gases” in section 7.3 is to be read as a reference to “500 ppmv of methane”; (h) in section 8.1.1.1, the reference compound is methane and the references to the “the calibration gas mixture” and “the calibration gas” are to be read as references to “500 ppmv of methane”; (i) section 8.1.1.2 is to be read only with reference to the first sentence of that section and the instrument response factor referred to in that sentence must be in relation to 500 ppmv of methane and be less than 10; (j) the calibration precision test referred to in section 8.1.2 must be performed before the instrument is first used on any day; (k) the reference to “the specified calibration gas” in section 8.1.2.1 is to be read as a reference to “500 ppmv of methane”; (l) the reference to “the calibration gas value” in section 8.1.2.2 is to be read as a reference to “500 ppmv of methane”; (m) the response time test referred to in section 8.1.3 must be performed before the instrument is first used on any day; (n) the reference to “the specified calibration gas” in section 8.1.3.1 is to be read as a reference to “500 ppmv of methane”; and (o) the references to “the calibration gas” and “the calibration gas value” in section 10.1 are to be read as reference to “500 ppmv of methane”. EPA OTM 51 adaptations — paragraph 19 (1)(b) (4) For the purposes of paragraph 19 (1)(b), with regards to EPA OTM 51, (a) the reference in Section 6.1.2 to “the operational limit of 500 ppm specified in the regulation” is to be read as a reference to “500 ppmv of methane”; and (b) the reference in Section 7.1.2 to “the 500 ppm above background operational limit specified in the regulation” is to be read as a reference to “500 ppmv of methane”.
