The facility operates in the Primary Metals sector. The primary release pathway is air releases, accounting for 100% of total releases. All release data shown below is self-reported to the EPA under the Emergency Planning and Community Right-to-Know Act (EPCRA) Section 313.
Where this facility sits in the TRI record
Among the 1,603 Primary Metals facilities in this database, Wolverine Bronze Co reports the 1,008th-largest volume (1.3K lbs). Its reported volume is concentrated rather than spread: Copper alone is 100% 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.
Wolverine Bronze Co files annual Form R disclosures to the EPA Toxics Release Inventory under EPCRA Section 313, classified under NAICS 331524 (Primary Metals). Across 5 years of records spanning 2019–2023, the site has disclosed 1.3K lbs in cumulative toxic releases across 2 distinct chemicals.
The dominant release pathway is air releases at 1.3K lbs (99.8% of total volume), followed by off-site transfers at 0.2%. Between 2019 and 2023, reported totals decreased by 41% - from 340 lbs to 200 lbs.
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 Wolverine Bronze Co 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.
