Of the chemicals reported, 8 are classified as carcinogens, representing 27% of the facility's chemical profile. The facility operates in the Metal Mining sector. The primary release pathway is land disposal, accounting for 96% of total releases. All release data shown below is self-reported to the EPA under the Emergency Planning and Community Right-to-Know Act (EPCRA) Section 313.

#53 of 25,902 TRI facilities nationwide by total reported releases - among the top 0.2% of reporting sites by volume. Ranking reflects reported pounds, not toxicity or health risk.

Pogo Mine files annual Form R disclosures to the EPA Toxics Release Inventory under EPCRA Section 313, classified under NAICS 212221 (Metal Mining). Across 5 years of records spanning 2019–2023, the site has disclosed 34.9M lbs in cumulative toxic releases across 30 distinct chemicals, 8 of which (27%) carry a carcinogenic classification.

The dominant release pathway is land disposal at 33.7M lbs (96.3% of total volume), followed by water discharges at 3.6%. Between 2019 and 2023, reported totals increased by 38% - from 6.1M lbs to 8.4M 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 Pogo Mine 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.
