EPA TRI Category Code: N100

Copper and Copper Compounds (EPA TRI Category Code N100) is a chemical tracked by the EPA Toxics Release Inventory (TRI) program under Section 313 of the Emergency Planning and Community Right-to-Know Act. The TRI requires industrial facilities above specified threshold quantities to disclose annual manufacturing, processing, and otherwise-used volumes, along with quantities released to air, water, land, and off-site transfers.

Across the United States, 1,089 facilities have filed TRI Form R disclosures for Copper and Copper Compounds, with a cumulative reported release volume of 416.6M lbs. The chemical is not flagged as a carcinogen in the TRI classification set. The largest individual disclosure in the current dataset comes from KENNECOTT UTAH COPPER MINE CONCENTRATORS & POWER PLANT in UT at 94.4M lbs.

TRI volumes are self-reported estimates, not measured stack emissions, and each pound counts equally regardless of chemical toxicity, so total pounds should not be equated with total risk. Inclusion of a chemical or facility in the TRI does not itself establish a health hazard; it documents the public right-to-know record. Consult EPA's IRIS (Integrated Risk Information System) and the Agency for Toxic Substances and Disease Registry for health-effect summaries.

How much Copper and Copper Compounds is released in the U.S.?
U.S. facilities have reported a total of 416.6M lbs of Copper and Copper Compounds releases to the EPA Toxic Release Inventory across 1,089 facilities. Release quantities are self-reported estimates. This includes releases to air, water, land, and off-site transfers.
Is Copper and Copper Compounds harmful to health?
Copper and Copper Compounds is not classified as a carcinogen in the EPA TRI database. Health effects depend on exposure levels, duration, and route. For specific health questions, consult a toxicologist or your local health agency.
Which facilities release the most Copper and Copper Compounds?
The largest reported releasers of Copper and Copper Compounds include facilities across multiple states. Release data is self-reported annually to the EPA under the TRI program. View the full list of 1,089 facilities on this page.
Why is Copper and Copper Compounds listed under code N100 instead of a CAS number?
N100 is an EPA TRI Category Code, not a CAS Registry Number. EPA assigns category codes (N-prefix and K-prefix) to chemical groups that share reporting requirements, for example, "Copper and Copper Compounds" covers many distinct compounds aggregated for TRI reporting. Individual constituents may have their own CAS Registry Numbers (e.g., elemental Lead is CAS 7439-92-1), but the group is reported under the single TRI Category Code.

Health Information

Data comes from the EPA Toxic Release Inventory (TRI) program. Release quantities are self-reported by facilities and may represent estimates. The total shown aggregates reports across all facilities and reporting years.

PlainEnviro presents this data without advocacy framing. The presence of a chemical in the TRI database does not by itself indicate a health risk at current exposure levels. For health-related questions about specific chemical exposures, consult your local health agency or a toxicologist.
