Reciprocating Compressor Reporting (Onshore Petroleum and Natural Gas Production)
The reporting requirements for Onshore Petroleum and Natural Gas Production differ from the rest of the industry segments for this source type. For Onshore Petroleum and Natural Gas Production, only the following two emission values are required to be reported:
- The total annual CO2 emissions from all compressors combined, in metric tons CO2 [98.236(c)(14)(v)(B)
...
- ]
...
- The

Reciprocating Compressor Reporting (Onshore Natural Gas Processing, Onshore Natural Gas Transmission Compression, Underground Natural Gas Storage, Liquified Natural Gas (LNG) Storage, and LNG Import and Export Equipment)
All applicable industry segments other than Onshore Petroleum and Natural Gas Production must report emissions individually for each reciprocating compressor.
For each compressor, emissions will be reported by mode of operation. Three modes of operation that require emission monitoring are the operating mode, standby, pressurized mode, and the not operating, depressurized mode. Emissions from each mode of operation must be reported if the compressor was ever in that mode at anytime during the year.
For each emission source, there are separate reporting fields for if the emission source was measured during the year or if the emission source was not measured and a default emission factor was applied. If one or more sources for a compressor were measured during the year, the emissions should be filled in for the respective measured fields. For any sources that emissions were not directly measured, the not measured field should be reported in place of the measured fields. If BAMM was used and no emission sources were measured, the compressor specific BAMM field should be reported as “yes”, and only the not measured emission fields should be reported. If BAMM was not used in place of direct measurement of at least one mode, then “no” should be entered for the BAMM field. In no occurrence should the measured and not measured fields both be populated for a given compressor and source type.
