Facility Insight: Texas Gas Transmission - Calvert City Station

Texas Gas Transmission - Calvert City Station (EPA GHGRP Facility ID 1009463) reported 23K metric tons of CO2-equivalent in 2023, operating in Benton, KY within MARSHALL COUNTY. 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 13 years of reported data on record, covering the 2011–2023 window. Over that period, annual CO2e emissions declined by 51.5%, with the peak observed year showing up to 66K 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 KY should cross-reference with the state-level rollup on our KY 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.
