The Oregon Department of Environmental Quality proposes to amend air quality regulations. The changes would ensure that the state's NESHAPs and new source performance standards will be consistent with EPA guidelines. Public hearings will be held on August 18, 19, and 21, 2008. Comments are due August 26, 2008. http://www.deq.state.or.us/aq/rules/nsps/PublicNotice.pdf.
