Where this facility sits in the TRI record
Among the 3,421 Fabricated Metals facilities in this database, Carpenter Technology Corp reports the 962nd-largest volume (20.4K lbs). Carcinogen-classified chemicals make up 63.8% of the reported pounds, not just of the chemical count.
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.
Carpenter Technology Corp files annual Form R disclosures to the EPA Toxics Release Inventory under EPCRA Section 313, classified under NAICS 332111 (Fabricated Metals). Across 5 years of records spanning 2019–2023, the site has disclosed 20.4K lbs in cumulative toxic releases across 7 distinct chemicals, 2 of which (29%) carry a carcinogenic classification. Largest chemicals by pounds: Nickel; Chromium; Copper; Cobalt.
