Occupational Safety and Health Administration (OSHA) Carcinogens
Some chemicals that are reportable to the TRI Program are included on OSHA’s list of carcinogens. EPA refers to these chemicals as TRI OSHA carcinogens. These chemicals are either known or believed to cause cancer in humans. A list of the TRI carcinogens can be found in the TRI basis of OSHA carcinogens technical document (pdf).
This map shows the locations of the facilities that reported carcinogens to TRI for 2022, sized by their relative release quantities to air. Zoom in to view demographic data for communities around these facilities. Click on a facility for more details on its reporting.

This graph shows the 10-year trend in air releases of TRI OSHA carcinogens.
From 2013 to 2022:
- Air releases of TRI OSHA carcinogens increased by 4% since 2013.
- While most sectors reduced their air releases of many of these carcinogens, these decreases were offset by increased releases of styrene by the plastics and rubber products manufacturing sector and the transportation equipment manufacturing sector.
- In 2022, the TRI OSHA carcinogens released into air in the highest quantities were styrene, acetaldehyde, and formaldehyde.
- EPA recently added natural gas processing facilities to the scope of facilities required to report to TRI. These facilities reported for the first time for 2022, contributing to the increase in reported air releases of TRI OSHA carcinogens.
