Navigating Cleaner Air Oregon (CAO)

To track emissions at the national level, the United States Environmental Protection Agency (EPA) requires Oregon (and other states) to conduct statewide inventories from all sources of air pollution. These data collected from across the country are used for making new rules and modeling air pollution.

A few years in the making, Cleaner Air Oregon (CAO) addresses this need and is already affecting many companies in the state. As of November 2018, all permitted facilities should have already submitted emissions inventories for their sources to the Oregon Department of Environmental Quality (DEQ).

In addition to closing previous loopholes, CAO evaluates potential air toxics health risks (for cancer and non-cancer health effects) to people living, working or going to school near industrial and commercial facilities, and reduces those risks to below action levels adopted in law or rules.

Air Toxics: Designing an Affordable Monitoring Network

The state of Oregon has proposed a new set of rules, currently in the draft state, for a risk-based air toxics permitting program; the program is named “Cleaner Air Oregon.” The stated goal of Cleaner Air Oregon is to reduce health risks from existing industrial facilities to below 100 in 1 million by 2030. To accomplish this goal, the state of Oregon will require emissions reductions from facilities for which the aggregate health risk, based on predicted health risk from 260 chemicals with known health-protective levels, is above the 100 in 1 million threshold.
