Where this facility sits in the TRI record
Among the 1,603 Transportation Equipment facilities in this database, Gm Truck Group Flint Assembly Plant reports the 10th-largest volume, placing it in the top 0.6% of its sector. This one site accounts for 96.8% of every pound reported in Genesee. Its reported volume is concentrated rather than spread: Certain glycol ethers alone is 72.6% of the total.
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.
Gm Truck Group Flint Assembly Plant files annual Form R disclosures to the EPA Toxics Release Inventory under EPCRA Section 313, classified under NAICS 336112 (Transportation Equipment). Across 5 years of records spanning 2019–2023, the site has disclosed 2.2M lbs in cumulative toxic releases across 23 distinct chemicals, 7 of which (30%) carry a carcinogenic classification.
The dominant release pathway is air releases at 2.1M lbs (97.7% of total volume), followed by off-site transfers at 2.3%. Between 2019 and 2023, reported totals increased by 81% - from 304.2K lbs to 550.5K lbs. The facility is operated under parent company General Motors LLC.
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 Gm Truck Group Flint Assembly Plant has filed with the EPA under federal community right-to-know requirements.

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.
Release quantities are self-reported by the facility and may represent estimates rather than exact measurements. "Total releases" includes releases to air, water, land, and off-site transfers for disposal. Quantities shown here are aggregated across all available reporting years.
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.
