Where this facility sits in the TRI record

Among the 3,421 Fabricated Metals facilities in this database, Stockton Steel reports the 2,023rd-largest volume (257 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.

Stockton Steel files annual Form R disclosures to the EPA Toxics Release Inventory under EPCRA Section 313, classified under NAICS 332312 (Fabricated Metals). Across 5 years of records spanning 2019–2023, the site has disclosed 257 lbs in cumulative toxic releases across 4 distinct chemicals, 1 of which (25%) carry a carcinogenic classification.

The dominant release pathway is air releases at 257 lbs (100.0% of total volume), followed by land disposal at 0.0%. Between 2019 and 2023, reported totals decreased by 58% - from 74 lbs to 31 lbs. The facility is operated under parent company The Herrick Corp.

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 Stockton Steel 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.
