## Abstract

The Environmental Protection Agency (EPA) is approving revisions to the Oregon State Implementation Plan (SIP) submitted on December 11, 2018. The revisions update the SIP to allow for electronic public notice of proposed major stationary source permits, add references to stationary source sampling requirements, make use of plain language, and correct errors. The EPA has determined the changes are consistent with Clean Air Act requirements.
