The goal of the
Cleaner Air Oregon program is to evaluate the potential health risks to people who live, work, or play in areas impacted by
regulated toxic air contaminants emitted from permitted industrial facilities, and ensure those risks meet
health-based standards. DEQ has compiled technical resources to assist
regulated sources and their consultants in the CAO health-risk assessment

Proposed Noncancer Hazard Index Rules: Lists the 156
chemicals with developmental or other severe human health effects and the 26
chemicals not expected to have developmental or other severe health effects.
There is also a detailed table of the 156 chemicals,
which shows the lines of evidence used to identify that a chemical is expected
to have developmental and/or other severe health effects.

- EPA Integrated Risk Information
EPA’s IRIS Program supports this mission by identifying and
characterizing the health hazards of chemicals found in the environment.
Each IRIS assessment can cover a chemical, a group of related chemicals,
or a complex mixture.
Provisional Peer-Reviewed Toxicity Values:
EPA’s PPRTV Program supports the Agency’s mission to protect human
health and the environment by identifying and characterizing the health
hazards of, and providing an important source of toxicity information and
toxicity values for, chemicals of concern to the Superfund Program.

Environmental Health Hazard Assessment: OEHHA is the lead state agency for the assessment of health risks
posed by environmental contaminants.
