RE: Permanent rule updates to Ambient Air Quality Standards for nitrogen dioxide, sulfur dioxide and lead, and adoption of 1-hour Significant Impact Levels for nitrogen dioxide and sulfur dioxide.

Greetings permit holder,

This letter is to inform you about proposed rule amendments that may affect your activities. DEQ is developing a rulemaking proposal to update the Oregon Administrative Rules as required by the Clean Air Act.

The proposed rule changes are necessary to align state rules with Section 110 requirements of the Clean Air Act by revising the rule language for the lead ambient air quality standards for consistency with the federal national ambient air quality standards, adopting the 1-hour ambient air quality standards for nitrogen dioxide and sulfur dioxide, and adopting 1-hour significant impact levels for nitrogen dioxide and sulfur dioxide. If approved, these amendments will be submitted to the U.S. Environmental Protection Agency for approval as revisions to the Oregon State Clean Air Act Implementation Plan.

What this means to you

If the above proposed rule amendments are approved by the Environmental Quality Commission, DEQ will require a demonstration by permit holders that significant increases of nitrogen dioxide and sulfur dioxide emissions do not cause or contribute to a violation of the 1-hour standards when an air quality impact analysis is required by either the Plant Site Emission Limit or Prevention of Significant Deterioration) programs. If an analysis is required, the analysis must be conducted in accordance with a modeling protocol approved by DEQ and the results must be included in the application for a new or modified permit.

DEQ will propose the permanent rule amendments to the commission for adoption in October 2013. You may submit comments in writing to Carrie Capp by mail, fax, or e-mail, or you may attend the public hearing and submit written comments or provide testimony. It is not necessary to attend the hearing in order to comment. Written comments received prior to the deadline are treated equally with oral comments. To be considered, your comments must be received prior to the comment deadline of 5 p.m. on Aug. 19, 2013. Receipt of e-mail comments will be acknowledged immediately. Written comments may be mailed to Carrie Capp, Oregon DEQ, Air Quality Division, 811 SW Sixth Avenue, Portland, OR 97204. Comments may be e-mailed to: comment-SIP.SO2.NO2.Lead@deq.state.or.us or faxed to Carrie Capp at 503-229-5675.
