State of Oregon Clean Air Act Implementation Plan

(1) This implementation plan, consisting of Volumes 2 and 3 of the State of Oregon Air Quality 

Control Program, contains control strategies, rules and standards prepared by DEQ and is 

adopted as the state implementation plan (SIP) of the State of Oregon pursuant to the federal 

Clean Air Act, 42 U.S.C.A 7401 to 7671q. 

(2) Except as provided in section (3), the Commission will revise the SIP pursuant to the 

rulemaking procedures in division 11 of this chapter and any other requirements contained in the 

SIP and will direct DEQ to submit such revisions to the United States Environmental Protection 

Agency for approval. The Commission last adopted revisions to the State Implementation Plan 

on June 19, 2014[April 16, 2015]. 

(3) Notwithstanding any other requirement contained in the SIP, DEQ may: 

(a) Submit to the Environmental Protection Agency any permit condition implementing a rule 

that is part of the federally-approved SIP as a source-specific SIP revision after DEQ has 

complied with the public hearings provisions of 40 CFR 51.102 (July 1, 2002); and 

(b) Approve the standards submitted by a regional authority if the regional authority adopts 

verbatim any standard that the Commission has adopted, and submit the standards to EPA for 

approval as a SIP revision. 

NOTE: Revisions to the State of Oregon Clean Air Act Implementation Plan become federally 

enforceable upon approval by the United States Environmental Protection Agency. If any 

provision of the federally approved Implementation Plan conflicts with any provision adopted by 

the Commission, DEQ shall enforce the more stringent provision.
