DEQ proposes to streamline, reorganize and update Oregon’s air quality permit rules and proposes changes to statewide particulate matter emission standards and the preconstruction permitting program. The changes would help Oregon comply with the U.S. Environmental Protection Agency’s ambient air quality standard for fine particulates, commonly called PM2.5 and protect air quality through Oregon’s permitting programs.
