General Air Quality Definitions

As used in divisions 200 through 268, unless specifically defined otherwise:

(1) "Act" or "FCAA" means the Federal Clean Air Act, 42 U.S.C.A. 7401 to 7671q.

(2) "Activity" means any process, operation, action, or reaction (e.g., chemical) at a source that emits a regulated pollutant.

(3) "Actual emissions" means the mass emissions of a pollutant from an emissions source during a specified time period.

(a) For determining actual emissions as of the baseline period:

(A) Except as provided in paragraphs (B) and (C) of this subsection and subsection (b) of this section, actual emissions equal the average rate at which the source actually emitted the pollutant during an applicable baseline period and that represents normal source operation;

(B) DEQ presumes that the source-specific mass emissions limit included in a source's permit that was effective on September 8, 1981 is equivalent to the source's actual emissions during the applicable baseline period if it is within 10% of the actual emissions calculated under paragraph (A) of this subsection.

(C) Actual emissions equal the potential to emit of the source for the sources listed in paragraphs (i) through (iii) of this paragraph. The actual emissions will be reset if required in accordance with subsection (c) of this section.

(i) Any source or part of a source that had not begun normal operations during the applicable baseline period but was approved to construct and operate before or during the baseline period in accordance with OAR 340 division 210, or

(ii) Any source or part of a source of greenhouse gases that had not begun normal operations prior to January 1, 2010, but was approved to construct and operate prior to January 1, 2011 in accordance with OAR 340 division 210, or

(iii) Any source or part of a source that had not begun normal operations during the applicable baseline period and was not required to obtain approval to construct and operate before or during the applicable baseline period.

(b) For any source or part of a source that had not begun normal operations during the applicable baseline period, but was approved to construct and operate in accordance with OAR 340 division 224, actual emissions on the date the permit is issued equal the potential to emit of the source. The actual emissions will be reset if required in accordance with subsection (c) of this section.

(c) Where actual emissions equal potential to emit under paragraph (a)(C) or subsection (b) of this section, the potential emissions will be reset to actual emissions as follows:

(A) Paragraphs (A) through (D) of this subsection apply to sources whose actual emissions of greenhouse gases were determined pursuant paragraph (3)(a)(C), and to all other sources of all other regulated pollutants that are permitted in accordance with OAR division 224 on or after May 1, 2011.

(B) Except as provided in paragraph (D) of this subsection, ten years from the end of the applicable baseline period under paragraph (a)(C) or ten years from the date the permit is issued under subsection (b), or an earlier time if requested by the source in a permit application involving public notice, DEQ will reset actual emissions to equal the highest actual emission rate during any consecutive 12-month period during the ten year period or any shorter period if requested by the source.

(C) Any emission reductions achieved due to enforceable permit conditions based on OAR 340-226-0110 and 0120 (highest and best practicable treatment and control) are not included in the reset calculation required in paragraph (B) of this subsection.

(D) DEQ may extend the date of resetting by five additional years upon satisfactory demonstration by the source that construction is ongoing or normal operation has not yet been achieved.

(d) For determining actual emissions for Emission Statements under OAR 340-214-0200 through 340-214-0220 and Oregon Title V Operating Permit Fees under OAR 340 division 220, actual emissions include, but are not limited to, routine process emissions, fugitive emissions, excess emissions from maintenance, startups and shutdowns, equipment malfunction, and other activities, except categorically insignificant activities and secondary emissions.

(e) For Oregon Title V Operating Permit Fees under OAR 340 division 220, actual emissions must be directly measured with a continuous monitoring system or calculated using a material balance or verified emission factor determined in accordance with division 220 in combination with the source's actual operating hours, production rates, or types of materials processed, stored, or combusted during the specified time period.

(4) "Adjacent" means interdependent facilities that are nearby to each other.

(b) Any consecutive 12 calendar month period during the calendar years 2000 through 2010 for greenhouse gases.

(15) "Best Available Control Technology" or "BACT" means an emission limitation, including, but not limited to, a visible emission standard, based on the maximum degree of reduction of each air contaminant subject to regulation under the Act which would be emitted from any proposed major source or major modification which, on a case-by-case basis, taking into account energy, environmental, and economic impacts and other costs, is achievable for such source or modification through application of production processes or available methods, systems, and techniques, including fuel cleaning or treatment or innovative fuel combustion techniques for control of such air contaminant. In no event may the application of BACT result in emissions of any air contaminant that would exceed the emissions allowed by any applicable new source performance standard or any standard for hazardous air pollutant. If an emission limitation is not feasible, a design, equipment, work practice, or operational standard, or combination thereof, may be required. Such standard must, to the degree possible, set forth the emission reduction achievable and provide for compliance by prescribing appropriate permit conditions.

(16) "Biomass" means non-fossilized and biodegradable organic material originating from plants, animals, and micro-organisms, including products, byproducts, residues and waste from agriculture, forestry, and related industries as well as the non-fossilized and biodegradable organic fractions of industrial and municipal wastes, including gases and liquids recovered from the decomposition of non-fossilized and biodegradable organic matter.

(A) Subsection (c) of this section does not apply to PM2.5 and greenhouse gases.

(B) Changes to the PSEL solely due to the availability of better emissions information are exempt from being considered an increase.

(d) If a portion of the netting basis or PSEL (or both) was set based on PTE because the source had not begun normal operations but was permitted or approved to construct and operate, that portion of the netting basis or PSEL (or both) must be excluded from the tests in subsections (a) and (b) of this section until the netting basis is reset as specified in the definitions of baseline emission rate and netting basis.

(D) Any source with a netting basis calculation resulting in a negative number.

(e) If a source relocates to an adjacent site, and the time between operation at the old and new sites is less than six months, the source may retain the netting basis from the old site.

(f) Emission reductions required by rule, order, or permit condition affect the netting basis if the source currently has devices or emissions units that are subject to the rules, order, or permit condition. The baseline emission rate is not affected. The netting basis reduction will be effective on the effective date of the rule, order, or permit condition requiring the reduction. The PSEL reduction will be effective on the compliance date of the rule, order, or permit condition.

(g) For permits issued after May 1, 2011 under New Source Review regulations in OAR 340 division 224, and where the netting basis initially equaled the potential to emit for a new or modified source, the netting basis will be reduced in accordance with the definition of actual emissions. Notwithstanding OAR 340-222-0041(2), this adjustment does not require a reduction in the PSEL.

(h) Emission reductions required by rule do not include emissions reductions achieved under OAR 340-226-0110 and 0120.

(i) Netting basis for a pollutant with a revised definition will be adjusted if the source is emitting the pollutant at the time of redefining and the pollutant is included in the permit's netting basis.

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.

(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.

Compliance Schedules

(1) The Department's goal is to encourage voluntary cooperation of all persons responsible for an air contamination source. To facilitate this cooperation and provide for a progressive program of air pollution control, the Department may negotiate with such persons to establish a compliance schedule for meeting the requirements contained in the applicable air quality rules or statutes. The schedule will set forth the conditions with which the responsible person must comply.

(a) The schedule may be accepted in lieu of a hearing. It must be in writing and signed by the Director of the Department or his designated officer and an authorized agent of the responsible person. After the schedule is executed by both parties, it must be confirmed by order of the Department;

(b) Compliance schedules providing for final compliance at a date later than 18 months from the date of execution must contain requirements for periodic reporting and increments of progress toward compliance, at intervals of less than 18 months;

(c) No compliance schedule may allow emissions on a permanent basis in excess of applicable standards and rules.

(2) If a negotiated schedule of compliance cannot be established, the Department may set a show cause hearing as provided by ORS 468.090 at a date and time designated as to why an order implementing a schedule proposed by the Department should not be adopted, or take such other authorized action as may be warranted.
