Natural Resources Committee

900 Court St. NE, S-407

Salem, Oregon 97301

Dear Chair Dingfelder:

This letter complies with ORS 183.335(15)(b), requiring notice of a proposed Department of Environmental Quality rulemaking.

DEQ is releasing for public review and comment a proposal to adopt new and amended federal air quality regulations that reduce air toxic emissions in Oregon. This rulemaking will update DEQ rules to ensure Oregon regulations are up to date with respect to federal air quality regulations.

The rule proposal would adopt by reference new federal standards regulating air toxic emissions from electric utility steam generating units, gold mine ore processing and production, and polyvinyl chloride and copolymers production, as well as changes to the federal gasoline dispensing facility rules. The rulemaking proposal would also clarify when and if Air Contaminant Discharge Permits are required for sources subject to federal standards.

The public comment period on the proposal runs through September 28, 2012. The Environmental Quality Commission will make a decision on the proposal at its March 2013 meeting.

The rulemaking announcement and documents will be posted on the Internet at http://www.deq.state.or.us/regulations/proposedrules.htm.

If you have questions or comments, please call Jerry Ebersole, Air Quality Program Operations, at 503-229-6974.

Sincerely,

Nicole Vick

DEQ Air Quality
