Where this facility sits in the TRI record
Among the 632 Other facilities in this database, W&t Offshore Inc. reports the 226th-largest volume (13.4K lbs).
Placement is computed from reported TRI pounds in this database. Thresholds are fixed across every facility page: concentrated ≥60% of volume in one chemical, county-dominant ≥25% of the county total, carcinogen-heavy ≥50% of pounds. Share-based statements are shown only for sites reporting at least 1,000 lbs, because a share of a very small total is not a meaningful signal. Reported pounds are self-reported estimates and do not measure toxicity or health risk.
W&t Offshore Inc. files annual Form R disclosures to the EPA Toxics Release Inventory under EPCRA Section 313, classified under NAICS 213111 (Other). Across 2 years of records spanning 2022–2023, the site has disclosed 13.4K lbs in cumulative toxic releases across 7 distinct chemicals, 2 of which (29%) carry a carcinogenic classification. Largest chemicals by pounds: n-Hexane; Hydrogen sulfide; Cyclohexane; Toluene.
The dominant release pathway is air releases at 13.4K lbs (100.0% of total volume). Between 2022 and 2023, reported totals increased by 4% - from 6.6K lbs to 6.8K lbs. Nearest other TRI reporters: Williams Mobile Bay Gas Processing Facility; Mobile Bay Gas Plant; Basf Trilon M; Skw Quab Chemicals. Similar-scale peers outside Alabama: US Naval Air Station Fallon Bravo 19; New Cooperative Inc. - Rowan Mill; US Dod Usaf Malmstrom Afb; US Dod Usaf Academy.
TRI Form R values are self-reported estimates, not measured stack emissions, and treat every pound of reported chemical equally regardless of toxicity. Inclusion in the TRI database does not establish a health risk to nearby residents; it documents the annual reporting record that W&t Offshore Inc. has filed with the EPA under federal community right-to-know requirements - open Williams Mobile Bay Gas Processing Facility for a different chemical mix before treating volume as risk.

About TRI Data
Data as of 2023 reporting year. Source: U.S. Environmental Protection Agency (EPA) Toxic Release Inventory.
Data comes from the EPA Toxic Release Inventory (TRI) program. Facilities that manufacture, process, or otherwise use listed toxic chemicals above threshold amounts are required to report annually to the EPA.
On this page the largest disclosed chemicals include n-Hexane, Hydrogen sulfide, Cyclohexane, Toluene; nearby reporters include Williams Mobile Bay Gas Processing Facility. "Total releases" includes air, water, land, and off-site transfers for disposal, aggregated across available reporting years. Quantities are self-reported estimates, not measured stack emissions.
PlainEnviro presents this data without advocacy framing. The presence of a facility in the TRI database does not by itself indicate a health risk. For site-specific health questions, consult your local environmental or health agency.
