Facility Insight: Columbia Gulf Transmission - Lake Arthur Compressor Station (Jennings, LA)

Columbia Gulf Transmission - Lake Arthur Compressor Station (Jennings, LA) (EPA GHGRP Facility ID 1014347) reported 33K metric tons of CO2-equivalent in 2023, operating in Jennings, LA within JEFFERSON DAVIS PARISH. The site is classified under Petroleum and Natural Gas Systems with NAICS code 486210, placing it within the group of U.S. facilities that cross the 25,000 MT CO2e annual reporting threshold set by EPA under 40 CFR Part 98. Self-reported emissions are verified by EPA staff, and the reported CO2e total aggregates CO2, methane (CH4), and nitrous oxide (N2O) weighted by their 100-year global warming potentials.

The facility has 3 years of reported data on record, covering the 2021–2023 window. Over that period, annual CO2e emissions rose by 22.9%, with the peak observed year showing up to 33K MT CO2e. Because facility emissions can swing year-to-year based on production volume, fuel mix, outages, or control upgrades, a single year rarely tells the full story — the emissions history table above unpacks CO2, CH4, and N2O contributions separately so readers can see which gas is driving the trend.

For context, this reported total captures Scope 1 direct emissions from on-site combustion, industrial processes, and fugitive sources — it excludes Scope 2 purchased electricity and Scope 3 upstream or downstream emissions. Users comparing this facility to others in LA should cross-reference with the state-level rollup on our LA emissions page and the parent company profile where linked, since facility-level disclosures are most meaningful when placed against the operator's broader portfolio. All underlying data is EPA-published and freely available via the GHGRP envirofacts API.
