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), revisions to the SIP will be made pursuant to the Commission’s rulemaking procedures in division 11 of this chapter and any other requirements contained in the SIP and will be submitted to the United States Environmental Protection Agency for approval. The State Implementation Plan was last modified by the Commission on [INSERT EQC ADOPTION DATE].
(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.

Sulfur Dioxide
Concentrations of sulfur dioxide in ambient air as measured by an approved method must not exceed:
(1) 0.02 ppm as an annual arithmetic mean for any calendar year at any site as measured by the reference method described in appendix A of 40 CFR part 50 (effective upon EQC adoption [INSERT EQC ADOPTION DATE]) or by an equivalent method designated in accordance with 40 CFR part 53 (effective upon EQC adoption [INSERT EQC ADOPTION DATE]).
(2) 0.10 ppm as a 24-hour average concentration more than once per calendar year at any site as measured by the reference method described in appendix A of 40 CFR part 50 (effective upon EQC adoption [INSERT EQC ADOPTION DATE]) or by an equivalent method designated in accordance with 40 CFR part 53 (effective upon EQC adoption [INSERT EQC ADOPTION DATE]).
(3) 0.50 ppm as a three-hour average concentration more than once per calendar year at any site as measured by the reference method described in appendix A of 40 CFR part 50 (effective upon EQC adoption [INSERT EQC ADOPTION DATE]).
(4) 0.075 ppm as a three-year average of the annual 99th percentile of the daily maximum 1-hour average concentration recorded at any monitoring site as determined by appendix T of 40 CFR part 50 (effective upon EQC adoption [INSERT EQC ADOPTION DATE]) as measured by a reference method based on appendix A or A-1 of 40 CFR part 50 (as of (effective upon EQC adoption [INSERT EQC ADOPTION DATE]), or by a Federal Equivalent Method (FEM) designated in accordance with 40 CFR part 53 (effective upon EQC adoption [INSERT EQC ADOPTION DATE]).

Nitrogen Dioxide
Concentrations of nitrogen dioxide in ambient air as measured by a reference method based on appendix F to 40 CFR part 50 (effective upon EQC adoption [INSERT EQC ADOPTION DATE]) or by a Federal equivalent method (FEM) designated in accordance with 40 CFR part 53 (effective upon EQC adoption [INSERT EQC ADOPTION DATE]) must not exceed:
(1) 0.053 ppm as an annual average concentration for any calendar year at any site. The standard is met when the annual average concentration in a calendar year is less than or equal to 0.053 ppm, as determined in accordance with appendix S of 40 CFR part 50 (effective upon EQC adoption [INSERT EQC ADOPTION DATE]) for the annual standard.
(2) 0.100 ppm as a 3-year average of the annual 98th percentile of the 1-hour daily maximum concentrations recorded at any monitoring site. The standards is met when the three-year average of the annual 98th percentile of the daily maximum 1-hour average concentration is less than or equal to 0.100 ppm, as determined in accordance with appendix S of 40 CFR Part 50 (effective upon EQC adoption [INSERT EQC ADOPTION DATE]) for the 1-hour standard.
(3) 0.053 ppm as an annual arithmetic mean concentration as determined in accordance with Appendix S of 40 CFR Part 50 (effective upon EQC adoption [INSERT EQC ADOPTION DATE]). The secondary standard is attained when the annual arithmetic mean concentration in a calendar year is less than or equal to 0.053 ppm, rounded to three decimal places (fractional parts equal to or greater than 0.0005 ppm must be rounded up). To demonstrate attainment, an annual mean must be based upon hourly data that are at least 75 percent complete or upon data derived from manual methods that are at least 75 percent complete for the scheduled sampling days in each calendar quarter.

Ambient Air Quality Standard for Lead
The concentration of lead and its compounds in ambient air must not exceed:
(1) 0.15 micrograms per cubic meter as a maximum arithmetic mean averaged over a calendar quarter, as measured by a reference method based on appendix G of 40 CFR Part 53 (effective upon EQC adoption [INSERT EQC ADOPTION DATE]) or an equivalent method designated in accordance with 40 CFR Part 53 (effective upon EQC adoption [INSERT EQC ADOPTION DATE]).
(2) The standard is met when the maximum arithmetic 3-month mean concentration for a 3-year period, as determined in accordance with appendix R of 40 CFR Part (effective upon EQC adoption [INSERT EQC ADOPTION DATE]), is less than or equal to 0.15 micrograms per cubic meter.
