Description This technical review and report contributes to a collaborative effort to characterize concentrations of sulfur dioxide (SO2)in the ambient air in Washington State. This characterization effort, which is mandatory for all states, began in 2010, when the U.S. Environmental Protection Agency (EPA) established a new National Ambient Air Quality Standard (NAAQS) for sulfur oxides (SOx). Ecology is joined by the Northwest Clean Air Agency (NWCAA) in collecting data and developing this technical analysis.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
