The Oregon Department of Environmental Quality proposed to adopt standards in Chapter 340 that implement or exceed amended federal air quality regulations. The expected result of this rule is the maintenance of Oregon's delegation of the federal standards, the use of low mercury coal and/or mercury controls in Oregon, and the reduction of benzene emissions in Oregon. http://arcweb.sos.state.or.us/rules/0808_Bulletin/0808_rulemaking_bulletin.html.
