Perfluorododecanoic Acid (CAS 307-55-1) 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.

A carcinogen flag, when present on other chemicals in this database, reflects an assessment from EPA, IARC, or the National Toxicology Program rather than a TRI-specific determination. The largest individual disclosure in the current dataset comes from US ECOLOGY NEVADA INC. in NV at 669 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 Perfluorododecanoic Acid is disclosed in U.S. TRI filings? ▼
U.S. facilities have reported a total of 1.4K lbs of Perfluorododecanoic Acid releases to the EPA Toxic Release Inventory across 7 facilities. Release quantities are self-reported estimates covering air, water, land, and off-site transfers. They are disclosure totals, not toxicity-weighted harm scores.
How does EPA TRI classify Perfluorododecanoic Acid? ▼
Perfluorododecanoic Acid is not marked as a carcinogen in the TRI classification set. TRI classification flags document inventory listing status; they are not a site-specific exposure or health diagnosis. For health-effect summaries see EPA IRIS and ATSDR toxicological profiles.
Which facilities disclose the most Perfluorododecanoic Acid? ▼
US Ecology Nevada Inc. in NV reports the largest disclosed release of Perfluorododecanoic Acid in this dataset, at 669 lbs. Most reporting facilities for this chemical fall under hazardous waste. Release data is self-reported annually to the EPA under the TRI program. View the full list of 7 facilities on this page.
What is the CAS number for Perfluorododecanoic Acid? ▼
The CAS (Chemical Abstracts Service) Registry Number for Perfluorododecanoic Acid is 307-55-1. CAS numbers are unique numerical identifiers assigned to every chemical substance described in the open scientific literature. This identifier is used to search scientific databases and regulatory filings.

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.
