The facility operates in the Primary Metals sector. The primary release pathway is off-site transfers, accounting for 98% of total releases.

Where this facility sits in the TRI record
Among the 1,603 Primary Metals facilities in this database, Metalor Technologies USA Corp Refining Div reports the 518th-largest volume (44.8K lbs). Its reported volume is concentrated rather than spread: Nitrate compounds (water dissociable; reportable only when in aqueous solution) alone is 98.4% 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.
Metalor Technologies USA Corp Refining Div files annual Form R disclosures to the EPA Toxics Release Inventory under EPCRA Section 313, classified under NAICS 331410 (Primary Metals). Across 6 years of records spanning 2019–2024, the site has disclosed 44.8K lbs in cumulative toxic releases across 9 distinct chemicals.
The dominant release pathway is off-site transfers at 66.4K lbs (98.4% of total volume), followed by air releases at 1.6%. Between 2019 and 2024, reported totals increased by 7987% - from 281 lbs to 22.7K 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 Metalor Technologies USA Corp Refining Div 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.
