If emissions were detected using a screening method, report only the method subsequently used to measure the volumetric emissions.(E) Measured flow rate, in standard cubic feet per hour.(F) If the measurement is for a manifolded group of crankcase vent sources, indicate the number of reciprocating internal compressor engines that were operating during measurement.(ii) Annual CH4 emissions from the reciprocating internal combustion engine crankcase vent, in metric tons CH4.(3) Reciprocating internal combustion engines with crankcase vents that calculate emissions according to § 98.233(ee)(2) must report the information specified in paragraphs (ee)(3)(i) through (iv) of this section.(i) Well-pad ID (for the onshore petroleum and natural gas production industry segment only) or gathering and boosting site ID (for the onshore petroleum and natural gas gathering and boosting industry segment only).(ii) Total number of reciprocating internal combustion engines with crankcase vents that were operational at some point in the calendar year at the well-pad site, gathering and boosting site, or facility, as applicable.(iii) Total time that the reciprocating internal combustion engines with crankcase venting were operational in the calendar year, in hours ("T" in equation W-46 to § 98.233 ).(iv) Annual CH4 emissions, in metric tons CH4, calculated according to § 98.233(ee)(2) . 79 FR 70411 , Nov. 24, 2014, as amended at 80 FR 64291 , Oct. 22, 2015; 81 FR 86515 , Nov. 30, 2016; 89 FR 42289 , May 14, 2024 81 FR 86515 , 1/1/2017; 89 FR 42289 , 7/15/2024; 89 FR 71848 , 10/4/2024; 89 FR 42293 , 1/1/2025; 89 FR 71846 , 1/1/2025
