RE: Opportunity to comment on updates to permitted activities and air quality standards in Oregon

You hold an air quality permit with DEQ. This email is to inform you about proposed rule amendments that may affect your permitted activities. DEQ is developing a rulemaking proposal to update Oregon Administrative Rules as required by the Clean Air Act.

DEQ is accepting public comment on proposed permanent rule revisions to update ambient air quality standards to match federally-revised National Ambient Air Quality Standards for nitrogen dioxide, sulfur dioxide and lead and to adopt new, 1-hour Significant Air Quality Impact Levels for nitrogen dioxide and sulfur dioxide. The amendments, if adopted, will be submitted to the US Environmental Protection Agency for approval as revisions to the Oregon State Implementation Plan, as required by the Clean Air Act.

The propose affects new or existing modified industrial sources that emit nitrogen dioxide, sulfur dioxide or lead. If the above proposed rule amendments are approved by the Oregon Environmental Quality Commission, DEQ will require a demonstration by permit holders that significant increases of NO₂ and SO₂ 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.

A public hearing will be held:

August 15, 2013 at 6:00 p.m.

Department of Environmental Quality, Conference Room EQC B
