Adm. Order No.: DEQ 5-2011

Filed with Sec. of State: 4-29-2011

Certified to be Effective: 5-1-11

Notice Publication Date: 11-1-2010

Rules Amended: 340-200-0020, 340-200-0025, 340-200-0040, 340-202-0010, 340-202-0060, 340-202-0210, 340-215-0060, 340-216-0020, 340-216-0025, 340-216-0040, 340-216-0052, 340-216-0054, 340-216-0056, 340-216-0060, 340-216-0064, 340-216-0066, 340-216-0070, 340-216-0090, 340-222-0042, 340-222-0045, 340-224-0010, 340-224-0050, 340-224-0060, 340-224-0070, 340-225-0020, 340-225-0030, 340-225-0045, 340-225-0050, 340-225-0060, 340-225-0090, 340-228-0300, 340-246-0230

Subject: PM2.5 New Source Review/Prevention of Significant Deterioration: The EQC amended rules to establish PM2.5 New Source Review/Prevention of Significant Deterioration (NSR/PSD) for fine particles (PM2.5 or particulate matter less than 2.5 microns in diameter.) The rules help DEQ and businesses implement NSR/PSD as the U.S. Environmental Protection Agency (EPA) intended.

Greenhouse Gas (GHG) Prevention of Significant Deterioration: The EQC amended Prevention of Significant Deterioration (PSD) rules to include greenhouse gases in response to EPA regulations and clarified NSR/PSD rules to allow DEQ to continue implementing the PSD program in Oregon.

Small Scale Renewable Energy Sources: EPA requires states to have minor source construction approval programs but gives states flexibility in how to do this. Oregon’s minor source construction approval program basically applies major source NSR/PSD requirements to any source with emissions over the significant emission rate (SER) including some areas where the Oregon SER is lower than the federal SER. HB 2952 revised how the minor source construction approval program works for small scale local energy projects. The EQC amended NSR/PSD rules to incorporate changes to ORS 468A.040 for small scale local energy projects.

Permitting Rule Updates: Oregon’s permitting rule incorporates the federal acid rain program rules by reference. The EQC amended the permitting rules to reference the federal acid rain rules updated July 2, 2010.

DEQ will submit these rules to the EPA as a revision to the State Implementation Plan, which is a requirement of the Clean Air Act.

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) The Department 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 pubic notice, the Department 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) The Department 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.

(5) “Affected source” means a source that includes one or more affected units that are subject to emission reduction requirements or limitations under Title IV of the FCAA.

(b) The baseline emission rate for greenhouse gases, on a CO2e basis, will be established with the first permitting action issued after July 1, 2011, provided the permitting action involved a public notice period that began after July 1, 2011.

(c) For a pollutant that becomes a regulated pollutant subject to OAR 340 division 224 after May 1, 2011, the initial baseline emission rate is the actual emissions of that pollutant during any consecutive 12 month period within the 24 months immediately preceding its designation as a regulated pollutant if a baseline period has not been defined for the pollutant.

(d) The baseline emission rate will be recalculated if actual emissions are reset in accordance with the definition of actual emissions.

(e) Once the baseline emission rate has been established or recalculated in accordance with subsection (d) of this section, the production basis for the baseline emission rate may only be changed if a material mistake or an inaccurate statement was made in establishing the production basis for baseline emission rate.

(14) “Baseline Period” means:

(a) Any consecutive 12 calendar month period during the calendar years 1977 or 1978 for any regulated pollutant other than greenhouse gases. The Department may allow the use of a prior time period upon a determination that it is more representative of normal source operation.

(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.

(42) “Emission Estimate Adjustment Factor” or “EEAF” means an adjustment applied to an emission factor to account for the relative inaccuracy of the emission factor.

(43) “Emission Factor” means an estimate of the rate at which a pollutant is released into the atmosphere, as the result of some activity, divided by the rate of that activity (e.g., production or process rate).

(44)(a) Except as provided in subsection (b) of this section, “Emission Limitation” and “Emission Standard” mean a requirement established by a State, local government, or the EPA which limits the quantity, rate, or concentration of emissions of air pollutants on a continuous basis, including any requirements which limit the level of opacity, prescribe equipment, set fuel specifications, or prescribe operation or maintenance procedures for a source to assure continuous emission reduction.

(b) As used in OAR 340-212-0200 through 340-212-0280, “Emission limitation or standard” means any applicable requirement that constitutes an emission limitation, emission standard, standard of performance or means of emission limitation as defined under the Act. An emission limitation or standard may be expressed in terms of the pollutant, expressed either as a specific quantity, rate or concentration of emissions (e.g., pounds of SO2 per hour, pounds of SO2 per million British thermal units of fuel input, kilograms of VOC per liter of applied coating solids, or parts per million by volume of SO2) or as the relationship of uncontrolled to controlled emissions (e.g., percentage capture and destruction efficiency of VOC or percentage reduction of SO2). An emission limitation or standard may also be expressed either as a work practice, process or control device parameter, or other form of specific design, equipment, operational, or operation and maintenance requirement. For purposes of 340-212-0200 through 340-212-0280, an emission limitation or standard does not include general operation requirements that an owner or operator may be required to meet, such as requirements to obtain a permit, to operate and maintain sources in accordance with good air pollution control practices, to develop and maintain a malfunction abatement plan, to keep records, submit reports, or conduct monitoring.

(a) A part of a source is any machine, equipment, raw material, product, or byproduct that produces or emits regulated air pollutants. An activity is any process, operation, action, or reaction (e.g., chemical) at a stationary source that emits regulated air pollutants. Except as described in subsection (d) of this section, parts and activities may be grouped for purposes of defining an emissions unit if the following conditions are met:

(A) The group used to define the emissions unit may not include discrete parts or activities to which a distinct emissions standard applies or for which different compliance demonstration requirements apply; and

(B) The emissions from the emissions unit are quantifiable.

(b) Emissions units may be defined on a pollutant by pollutant basis where applicable.

(c) The term emissions unit is not meant to alter or affect the definition of the term “unit” under Title IV of the FCAA.

(d) Parts and activities cannot be grouped for determining emissions increases from an emissions unit under OAR 340-224-0050 through 340-224-0070, or 340 division 210, or for determining the applicability of any New Source Performance Standard (NSPS).

(48) “EPA” or “Administrator” means the Administrator of the United States Environmental Protection Agency or the Administrator’s designee.

(49) “Equivalent method” means any method of sampling and analyzing for an air pollutant that has been demonstrated to the Department’s satisfaction to have a consistent and quantitatively known relationship to the reference method, under specified conditions. An equivalent method used to meet an applicable federal requirement for which a reference method is specified must be approved by EPA unless EPA has delegated authority for the approval to the Department.

(50) “Event” means excess emissions that arise from the same condition and occur during a single calendar day or continue into subsequent calendar days.

(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.

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 the Department of Environmental Quality 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 April 21, 2011.

(3) Notwithstanding any other requirement contained in the SIP, the Department 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 the Department 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.

Definitions

The definitions in OAR 340-200-0020 and this rule apply to this division. If the same term is defined in this rule and OAR 340-200-0020, the definition in this rule applies to this division.

(1) “Ambient Air” means that portion of the atmosphere external to buildings, to which the general public has access.

(2) “Ambient Air Monitoring Site Criteria” means the general probe siting specifications as set forth in Appendix E of 40 CFR 58.

(3) “Approved Method” means an analytical method for measuring air contaminant concentrations described or referenced in 40 CFR 50 and Appendices. These methods are approved by the Department of Environmental Quality.

(4) “Baseline Concentration” means:

(a) Except as provided in subsection (c), the ambient concentration level for sulfur dioxide and PM10 that existed in an area during the calendar year 1978. Actual emission increases or decreases occurring before January 1, 1978 must be included in the baseline calculation, except that actual emission increases from any source or modification on which construction commenced after January 6, 1975 must not be included in the baseline calculation;

(b) The ambient concentration level for nitrogen oxides that existed in an area during the calendar year 1988.

(c) For the area of northeastern Oregon within the boundaries of the Umatilla, Wallowa-Whitman, Ochoco, and Malheur National Forests, the ambient concentration level for PM10 that existed during the calendar year 1993. The Department allows the use of a prior time period if the Department determines that it is more representative of normal emissions.

(d) For PM10 in the Medford-Ashland AQMA: the ambient PM10 concentration levels that existed during the year that EPA redesignates the AQMA to attainment for PM10.

(e) The ambient concentration level for PM2.5 that existed in an area during the calendar year 2007.

(f) If no ambient air quality data is available in an area, the baseline concentration may be estimated using modeling based on actual emissions for the years specified in subsections (a) through (e) of this section.

(5) “Indian Governing Body” means the governing body of any tribe, band, or group of Indians subject to the jurisdiction of the United States and recognized by the United States as possessing power of self-government.

Applicability

This division applies to all sources referred to in Table 1. This division also applies to Oregon Title V Operating Permit program sources when an ACDP is required by OAR 340-218-0020 or 340-224-0010. Sources referred to in Table 1 are subject to fees as set forth in Table 2.

(1) No person may construct, install, establish, develop or operate any air contaminant source which is referred to in Table 1 without first obtaining an Air Contaminant Discharge Permit (ACDP) from the Department or Regional Authority, unless otherwise deferred from the requirement to obtain an ACDP in subsection (1)(c) or (d) of this rule. No person may continue to operate an air contaminant source if the ACDP expires, or is terminated or revoked; except as provided in OAR 340-216-0082.

(a) For portable sources, a single permit may be issued for operating at any area of the state if the permit includes the requirements from both the Department and Regional Authorities.

(b) The Department or Regional Authority where the portable source’s Corporate offices are located will be responsible for issuing the permit. If the corporate office of a portable source is located outside of the state, the Department will be responsible for issuing the permit.

(c) An air contaminant source required to obtain an ACDP or ACDP Attachment pursuant to a NESHAP or NSPS adopted by the Commission by rule is not required to submit an application for an ACDP or ACDP Attachment until four months after the effective date of the Commission’s adoption of the NESHAP or NSPS, and is not required to obtain an ACDP or ACDP Attachment until six months after the Commission’s adoption of the NESHAP or NSPS. In addition, the Department may defer the requirement to submit an application for, or to obtain an ACDP or ACDP Attachment, or both, for up to an additional twelve months.

(d) Gasoline dispensing facilities are not required to submit an application for an ACDP or ACDP Attachment until May 1, 2010 or obtain an ACDP or ACDP attachment until June 1, 2010. The Department may defer the requirement to submit an application for, or to obtain an ACDP or ACDP Attachment, or both, for up to an additional six months.

(e) Deferrals of Oregon permitting requirements do not relieve an air contaminant source from the responsibility of complying with federal NESHAP or NSPS requirements.

(2) No person may construct, install, establish, or develop any source that will be subject to the Oregon Title V Operating Permit program without first obtaining an ACDP from the Department or Regional Authority.

(3) No person may modify any source that has been issued an ACDP without first complying with the requirements of OAR 340-210-0205 through 340-210-0250.

(4) No person may modify any source required to have an ACDP such that the source becomes subject to the Oregon Title V Operating Permit program without complying with the requirements of OAR 340-210-0205 through 340-210-0250.

(5) No person may increase emissions above the PSEL by more than the de minimis levels specified in OAR 340-200-0020 without first applying for and obtaining a modified ACDP.

(6) Subject to the requirements in this Division, the Lane Regional Air Protection Agency is designated by the Commission as the permitting agency to implement the Air Contaminant Discharge Permit program within its area of jurisdiction. The Regional Agency’s program is subject to Department oversight. The requirements and procedures contained in this Division pertaining to the Air Contaminant Discharge Permit program shall be used by the Regional Agency to implement its permitting program until the Regional Agency adopts superseding rules which are at least as restrictive as state rules.

Construction ACDP

(1) Purpose. A Construction ACDP is a permit for approval of Type 3 construction or modification changes as specified in OAR 340-210-0220. The Construction ACDP includes requirements for the construction or modification of stationary sources or air pollution control equipment and does not by itself provide authorization to operate the new construction or modification. A new or modified Standard ACDP or Oregon Title V Operating Permit is required before operation of the new construction or modification. A Construction ACDP may be used for the following situations:

(a) For complex construction or modification projects that require an extended period of time to construct, the Construction ACDP may provide construction approval faster than issuance of a Standard ACDP or modified Standard ACDP because the operating requirements would not need to be included in the permit.

(b) For Oregon Title V Operating Permit sources, the Construction ACDP may include the requirements of OAR 340-218-0050 and follow the external review procedures in 340-218-0210 and 340-218-0230 so that the requirements may later be incorporated into the Oregon Title V Operating Permit by an administrative amendment. If the applicant elects to incorporate the Construction ACDP by administrative amendment, all of the application submittal, permit content, and permit issuance requirements of OAR 340 division 218 must be met for the Construction ACDP

(2) Application requirements. Any person requesting a Construction ACDP must:

(a) Submit an application in accordance with OAR 340-216-0040 and provide the information specified in 340-216-0040(1) as it relates to the proposed new construction or modification; and

(b) Provide a list of any applicable requirements related to the new construction or modification.

(3) Fees. Applicants for a Construction ACDP must pay the fees set forth in Table 2 of OAR 340-216-0020.

(4) Permit content. A Construction ACDP must include at least the following:

(a) A requirement that construction must commence within 18 months after the permit is issued;

(b) A requirement to construct in accordance with approved plans;

(d) Emission limits for affected stationary sources;

(e) Performance standards for affected stationary sources and air pollution control equipment;

(i) General ACDP conditions for incorporating generally applicable requirements;

(j) A requirement to modify the operating permit before commencing operation of the new construction or modification;

(k) A permit expiration date of no more than 5 years; and

(l) Oregon Title V Permit requirements as specified in OAR 340-218-0050, if the applicant requests the external review procedures in OAR 340-218-0210 and 340-218-0230.

(5) Permit issuance procedures:

(a) A Construction ACDP requires public notice in accordance with OAR 340 division 209 for Category III permit actions.

(b) For sources subject to the Oregon Title V Operating Permit program, the applicant may ask for the external review procedures in OAR 340-218-0210 and 340-218-0230 in addition to the requirements of OAR 340 division 209 to allow the Construction ACDP to be incorporated into the Oregon Title V Operating Permit later by an administrative amendment provided the requirements of (1)(b) are met.

(A) Non-technical modifications and non-NSR Basic and Simple technical modifications require public notice in accordance with OAR 340 division 209 for Category I permit actions.

(B) Non-NSR/PSD Moderate and Complex technical modifications require public notice in accordance with OAR 340 division 209 for Category II permit actions.

Short Term PSEL

(1) For sources located in areas with established short term SER (OAR 340-200-0020 Table 3), PSELs are required on a short term basis for those pollutants that have a short term SER. The short term averaging period is daily, unless emissions cannot be monitored on a daily basis. The averaging period for short term PSELs can never be greater than monthly.

(a) For existing sources, the initial short term PSEL will be set as:

(A) the lesser of the short term capacity or the current permit’s short term PSEL, if each is greater than or equal to the short term SER; or

(B) the generic PSEL, if either the short term capacity or the current short term PSEL is less than the short term SER.

(b) For new sources, the initial short term PSEL will be zero.

(2) If an applicant wants a short term PSEL at a rate greater than the initial short term PSEL, the applicant must:

(a) Demonstrate that the requested increase over the initial short term PSEL is less than the significant emission rate (Note: In this case new sources would get a generic PSEL); or

(b) For increases equal to or greater than the SER over the initial short term PSEL:

(A) Obtain offsets and demonstrate a net air quality benefit in accordance with OAR 340-225-0090;

(B) Obtain an allocation from an available growth allowance in accordance with the applicable maintenance plan; or

(C) For carbon monoxide, demonstrate that the source or modification will not cause or contribute to an air quality impact equal to or greater than 0.5 mg/m3 (8 hour average) and 2 mg/m3 (1 hour average).

(D) For federal major sources, demonstrate compliance with air quality related values (AQRV) protection in accordance with OAR 340-225-0070.

(3) Once the short term PSEL is increased pursuant to section (2) of this rule, the increased level becomes the initial short term PSEL for future evaluations.

Unassigned Emissions

(1) Purpose. The purpose of unassigned emissions is to track and manage the difference in the quantity of emissions between the netting basis and what the source could emit based on the facility’s current physical and operational design.

(2) Establishing unassigned emissions.

(a) Unassigned emissions equal the netting basis minus the source’s current PTE, minus any banked emission reduction credits. Unassigned emissions are zero if this result is negative.

(b) Unused capacity created after the effective date of this rule due to reduced potential to emit that is not banked or expired emission reduction credits (OAR 340-268-0030), increase unassigned emissions on a ton for ton basis.

(3) Maximum unassigned emissions.

(a) Except as provided in paragraph (c) of this section, unassigned emissions will be reduced to not more than the SER (OAR 340-200-0020 Table 2) on July 1, 2007 and at each permit renewal following this date.

(b) The netting basis is reduced by the amount that unassigned emissions are reduced.

(c) In an AQMA where the EPA requires an attainment demonstration based on dispersion modeling, unassigned emissions are not subject to reduction under this rule.

(4) Using unassigned emissions.

(a) Unassigned emissions may be used for internal netting to allow an emission increase at the existing source in accordance with the permit.

(b) Unassigned emissions may not be banked or transferred to another source.

(5) Upon renewal, modification or other reopening of a permit after July 1, 2002 the unassigned emissions will be established with an expiration date of July 1, 2007 for all unassigned emissions in excess of the SER. Each time the permit is renewed after July 1, 2007 the unassigned emissions will be established again and reduced upon the following permit renewal to no more than the SER for each pollutant in OAR 340-200-0020 Table 2.

(1) Lowest Achievable Emission Rate (LAER). The owner or operator must apply LAER for each nonattainment pollutant or precursor(s) emitted at or above the significant emission rate (SER). LAER applies separately to the nonattainment pollutant or precursor(s) if emitted at or above a SER over the netting basis.

(a) For a major modification, the requirement for LAER applies to the following:

(A) Each emissions unit that emits the nonattainment pollutant or precursor(s) and is not included in the most recent netting basis established for that pollutant; and

(B) Each emissions unit that emits the nonattainment pollutant or precursor (s) and is included in the most recent netting basis but has been modified and the modification resulted in an increase in actual emissions above the portion of the most recent netting basis attributable to the emissions unit or the nonattainment pollutant or precursor(s).

(b) For phased construction projects, the LAER determination must be reviewed at the latest reasonable time before commencing construction of each independent phase.

(c) When determining LAER for a change that was made at a source before the current NSR application, the Department will consider technical feasibility of retrofitting required controls provided:

(A) The change was made in compliance with NSR requirements in effect when the change was made, and

(B) No limit will be relaxed that was previously relied on to avoid NSR.

(d) Modifications to individual emissions units that increase the potential to emit less than 10 percent of the SER are exempt from this section unless:

(A) They are not constructed yet;

(B) They are part of a discrete, identifiable, larger project that was constructed within the previous 5 years and is equal to or greater than 10 percent of the SER; or

(2) Offsets and Net Air Quality Benefit. The owner or operator must obtain offsets and demonstrate that a net air quality benefit will be achieved as specified in OAR 340-225-0090.

(3) Additional Requirements:

(a) The owner or operator of a source that emits or has the potential to emit 100 tons per year or more of any regulated pollutant subject to this division must evaluate alternative sites, sizes, production processes, and environmental control techniques for the proposed source or modification and demonstrate that benefits of the proposed source or modification will significantly outweigh the environmental and social costs imposed as a result of its location, construction or modification.

(b) The owner or operator of a source that emits or has the potential to emit 100 tons per year or more of any regulated pollutant subject to this division must demonstrate that all major sources owned or operated by such person (or by an entity controlling, controlled by, or under common control with such person) in the state are in compliance, or are on a schedule for compliance, with all applicable emission limitations and standards under the Act.

Within a designated maintenance area, proposed major sources and major modifications of a maintenance pollutant, including VOC or NOx in a designated ozone maintenance area or SO2 or NOx in a designated PM2.5 maintenance area, must meet the requirements listed below:

(1) Best Available Control Technology (BACT). Except as provided in section (5) and (6) of this rule, the owner or operator must apply BACT for each maintenance pollutant or precursor(s) emitted at or above a significant emission rate (SER). BACT applies separately to the maintenance pollutant or precursor(s) if emitted at or above a SER over the netting basis.

(a) For a major modification, the requirement for BACT applies to the following:

(A) Each emissions unit that emits the maintenance pollutant or precursor(s) and is not included in the most recent netting basis established for that pollutant; and

(B) Each emissions unit that emits the maintenance pollutant or precursor (s) and is included in the most recent netting basis but has been modified and the modification resulted in an increase in actual emissions above the portion of the most recent netting basis attributable to the emissions unit or the maintenance pollutant or precursor(s).

(b) For phased construction projects, the BACT determination must be reviewed at the latest reasonable time before commencement of construction of each independent phase.

(c) When determining BACT for a change that was made at a source before the current NSR application, the technical and economic feasibility of retrofitting required controls may be considered, provided:

(A) The change was made in compliance with NSR requirements in effect when the change was made; and

(B) No limit is being relaxed that was previously relied on to avoid NSR.

(d) Modifications to individual emissions units that increase the potential to emit less than 10 percent of the significant emission rate are exempt from this section unless:

(A) They are not constructed yet;

(B) They are part of a discrete, identifiable larger project that was constructed within the previous 5 years and that is equal to or greater than 10 percent of the significant emission rate; or

(2) Air Quality Protection:

(a) Offsets and Net Air Quality Benefit. Except as provided in subsections (b), (c), (d) and (e) of this section, the owner or operator must obtain offsets and demonstrate that a net air quality benefit will be achieved in the area as specified in OAR 340-225-0090.

(b) Growth Allowance. The requirements of this section may be met in whole or in part in an ozone or carbon monoxide maintenance area with an allocation by the Department from a growth allowance, if available, in accordance with the applicable maintenance plan in the SIP adopted by the Commission and approved by EPA. An allocation from a growth allowance used to meet the requirements of this section is not subject to OAR 340-225-0090. Procedures for allocating the growth allowances for the Oregon portion of the Portland-Vancouver Interstate Maintenance Area for Ozone and the Portland Maintenance Area for Carbon Monoxide are contained in 340-242-0430 and 340-242-0440.

(c) In a carbon monoxide maintenance area, a proposed carbon monoxide major source or major modification is exempt from subsections (a) and (b) of this section if the owner or operator can demonstrate that the source or modification will not cause or contribute to an air quality impact equal to or greater than 0.5 mg/m3 (8 hour average) and 2 mg/m3 (1-hour average). The demonstration must comply with the requirements of OAR 340-225-0045.

(d) In a PM10 maintenance area, a proposed PM10 major source or major modification is exempt from subsection (a) of this section if the owner or operator can demonstrate, pursuant to the requirements of OAR 340-225-0045, that the source or modification will not cause or contribute to an air quality impact in excess of:

(A) 120 ug/m3 (24-hour average) or 40 ug/m3 (annual average) in the Grants Pass PM10 maintenance area;

(B) 140 ug/m3 (24-hour average) or 47 ug/m3 (annual average) in the Klamath Falls PM10 maintenance area; or

(C) 140 ug/m3 (24-hour average) or 45 ug/m3 (annual average) in the Lakeview PM10 maintenance area. In addition, a single source impact is limited to an increase of 5 ug/m3 (24-hour average) in the Lakeview PM10 maintenance area.

(e) Proposed major sources and major modifications located in or that impact the Salem Ozone Maintenance Area are exempt from OAR 340-225-0090 and section (2)(a) of this rule for VOC and NOx emissions with respect to ozone formation in the Salem Ozone Maintenance Area.

Prevention of Significant Deterioration Requirements for Sources in Attainment or Unclassified Areas

Within a designated attainment or unclassified area, proposed federal major sources and major modifications at federal major sources for the pollutant(s) for which the area is designated attainment or unclassified, must meet the requirements listed below:

(1) Best Available Control Technology (BACT). The owner or operator must apply BACT for each pollutant or precursor(s) emitted at or above a significant emission rate (SER). BACT applies separately to the pollutant or precursor(s) if emitted at or above a SER over the netting basis. In the Medford-Ashland AQMA, the owner or operator of any proposed new federal major PM10 source, or proposed major modification of a federal major PM10 source must comply with the LAER emission control technology requirement in 340-224-0050(1), and is exempt from the BACT provision of this section.

(a) For a major modification, the requirement for BACT applies to the following:

(A) Each emissions unit that emits the pollutant or precursor(s) and is not included in the most recent netting basis established for that pollutant; and

(B) Each emissions unit that emits the pollutant or precursor (s) and is included in the most recent netting basis but has been modified and the modification resulted in an increase in actual emissions above the portion of the most recent netting basis attributable to the emissions unit or the nonattainment pollutant or precursor(s).

(b) For phased construction projects, the BACT determination must be reviewed at the latest reasonable time before commencement of construction of each independent phase.

(c) When determining BACT for a change that was made at a source before the current NSR application, any additional cost of retrofitting required controls may be considered provided:

(A) The change was made in compliance with NSR requirements in effect at the time the change was made, and

(B) No limit is being relaxed that was previously relied on to avoid NSR.

(d) Modifications to individual emissions units that increase the potential to emit less than 10 percent of the significant emission rate are exempt from this section unless:

Definitions

The definitions in OAR 340-200-0020 and this rule apply to this division. If the same term is defined in this rule and 340-200-0020, the definition in this rule applies to this division.

(1) “Allowable Emissions” means the emissions rate of a stationary source calculated using the maximum rated capacity of the source (unless the source is subject to federally enforceable limits which restrict the operating rate, or hours of operation, or both) and the most stringent of the following:

(a) The applicable standards as set forth in 40 CFR Parts 60, 61 and 63;

(b) The applicable State Implementation Plan emissions limitation, including those with a future compliance date; or

(2) “Background Light Extinction” means the reference levels (Mm-1) shown in the estimates of natural conditions as referenced in the FLAG to be representative of the PSD Class I or Class II area being evaluated.

(3) “Baseline Concentration” means:

(b) The ambient concentration level for nitrogen oxides that existed in an area during the calendar year 1988.

(c) For the area of northeastern Oregon within the boundaries of the Umatilla, Wallowa-Whitman, Ochoco, and Malheur National Forests, the ambient concentration level for PM10 that existed during the calendar year 1993. The Department may allow the source to use an earlier time period if the Department determines that it is more representative of normal emissions.

(d) For PM10 in the Medford-Ashland AQMA: the ambient PM10 concentration levels that existed during the year that EPA redesignates the AQMA to attainment for PM10.

(e) The ambient concentration level for PM2.5 that existed in an area during the calendar year 2007.

(4) “Competing PSD Increment Consuming Source Impacts” means the total modeled concentration above the modeled Baseline Concentration resulting from increased emissions of all other sources since the baseline concentration year that are within the Range of Influence of the source in question. Allowable Emissions may be used as a conservative estimate, in lieu of Actual Emissions, in this analysis.

(5) “Competing NAAQS Source Impacts” means total modeled concentration resulting from allowable emissions of all other sources that are within the Range of Influence of the source in question.

(6) “FLAG” refers to the Federal Land Managers’ Air Quality Related Values Work Group Phase I Report — REVISED. See 75 Federal Register 66125, October 27, 2010.

(7) “General Background Concentration” means impacts from natural sources and unidentified sources that were not explicitly modeled. The Department may determine this as site-specific ambient monitoring or representative ambient monitoring from another location.

(8) “Predicted Maintenance Area Concentration” means the future year ambient concentration predicted by the Department in the applicable maintenance plan as follows:

(a) The future year (2015) concentrations for the Grants Pass UGB are 89 μg/m3 (24-hour average) and 21 μg/m3 (annual average).

(b) The future year (2015) concentrations for the Klamath Falls UGB are 114 μg/m3 (24-hour average) and 25 μg/m3 (annual average).

(c) The future year (2025) concentrations for the Lakeview UGB are 126 μg/m3 (24-hour average) and 27 μg/m3 (annual average).

(9) “Nitrogen Deposition” means the sum of anion and cation nitrogen deposition expressed in terms of the mass of total elemental nitrogen being deposited. As an example, Nitrogen Deposition for NH4NO3 is 0.3500 times the weight of NH4NO3 being deposited.

(10) “Ozone Precursor Distance” means the distance in kilometers from the nearest boundary of a designated ozone nonattainment or maintenance area within which a major new or modified source of VOC or NOx is considered to significantly affect that designated area. The determination of significance is made by either the formula method or the demonstration method.

(a) The Formula Method.

(A) For sources with complete permit applications submitted before January 1, 2003: D = 30 km

(B) For sources with complete permit applications submitted on or after January 1, 2003: D = (Q/40) x 30 km

(C) D is the Ozone Precursor Distance in kilometers. The value for D is 100 kilometers when D is calculated to exceed 100 kilometers. Q is the larger of the NOx or VOC emissions increase from the source being evaluated in tons/year, and is quantified relative to the netting basis.

(D) If a source is located at a distance less than D from the designated area, the source is considered to have a significant effect on the designated area. If the source is located at a distance equal to or greater than D, it is not considered to have a significant effect.

(b) The Demonstration Method. An applicant may demonstrate to the Department that the source or proposed source would not significantly impact a nonattainment area or maintenance area. This demonstration may be based on an analysis of major topographic features, dispersion modeling, meteorological conditions, or other factors. If the Department determines that the source or proposed source would not significantly impact the nonattainment area or maintenance area under high ozone conditions, the Ozone Precursor Distance is zero kilometers.

(11) “Ozone Precursor Offsets” means the emission reductions required to offset emission increases from a major new or modified source located inside the designated nonattainment or maintenance area or within the Ozone Precursor Distance. Emission reductions must come from within the designated area or from within the Ozone Precursor Distance of the offsetting source as described in OAR 340-225-0090. The offsets determination is made by either the formula method or the demonstration method.

(a) The Formula Method.

(A) Required offsets (RO) for new or modified sources are determined as follows:

(i) For sources with complete permit applications submitted before January 1, 2003: RO = SQ

(ii) For sources with complete permit applications submitted on or after January 1, 2003: RO = (SQ minus (40/30 * SD))

(B) Contributing sources may provide offsets (PO) calculated as follows: PO = CQ minus (40/30 * CD)

(C) Multiple sources may contribute to the required offsets of a new source. For the formula method to be satisfied, total provided offsets (PO) must equal or exceed the required offset (RO).

(D) Definitions of factors used in paragraphs (A) (B) and (C) of this subsection:

(i) RO is the required offset of NOx or VOC in tons per year as a result of the source emissions increase. If RO is calculated to be negative, RO is set to zero;

(ii) SQ is the source emissions increase of NOx or VOC in tons per year above the netting basis;

(iii) SD is the source distance in kilometers to the nonattainment or maintenance area. SD is zero for sources located within the nonattainment or maintenance area.

(iv) PO is the provided offset from a contributing source and must be equal to or greater than zero;

(v) CQ is the contributing emissions reduction in tons per year quantified relative to contemporaneous pre-reduction actual emissions (OAR 340-268-0030(1)(b)).

(vi) CD is the contributing source distance in kilometers to the nonattainment or maintenance area. For a contributing source located within the nonattainment or maintenance area, CD equals zero.

(b) The Demonstration Method. An applicant may demonstrate to the Department using dispersion modeling or other analyses the level and location of offsets that would be sufficient to provide actual reductions in concentrations of VOC or NOx in the designated area during high ozone conditions. The modeled reductions of ambient VOC or NOx concentrations resulting from the emissions offset must be demonstrated over a greater area and over a greater period of time within the designated area as compared to the modeled ambient VOC or NOx concentrations resulting from the emissions increase from the source subject to this rule. If the Department determines that the demonstration is acceptable, then the Department will approve the offsets proposed by the applicant. The demonstration method does not apply to sources located inside an ozone nonattainment area.

(12) “Range of Influence (ROI)” means:

(a) For PSD Class II and Class III areas, the Range of Influence of a competing source (in kilometers) is defined by:

(A) ROI (km) = Q (tons/year) / K (tons/year km).

(B) Definition of factors used in paragraph (A) of this subsection:

(i) ROI is the distance a source has an effect on an area and is compared to the distance from a potential competing source to the Significant Impact Area of a proposed new source. Maximum ROI is 50 km, however the Department may request that sources at a distance greater than 50 km be included in a competing source analysis.

(ii) Q is the emission rate of the potential competing source in tons per year.

(iii) K (tons/year km) is a pollutant specific constant as defined in the table below:

(b) For PSD Class I areas, the Range of Influence of a competing source includes emissions from all sources that occur within the modeling domain of the source being evaluated. The Department determines the modeling domain on a case-by-case basis.

(13) “Source Impact Area” means a circular area with a radius extending from the source to the largest distance to where predicted impacts from the source or modification equal or exceed the Class II Significant Air Quality Impact levels set out in OAR 340-200-0020 Table 1. This definition only applies to PSD Class II areas and is not intended to limit the distance for PSD Class I modeling.

(14) “Sulfur Deposition” means the sum of anion and cation sulfur deposition expressed in terms of the total mass of elemental sulfur being deposited. As an example, sulfur deposition for (NH4)2SO4 is 0.2427 times the weight of (NH4)2SO4 being deposited.

Requirements for Analysis in PSD Class II and Class III Areas

Modeling: For determining compliance with the NAAQS and PSD Increments in PSD Class II and Class III areas, the following methods must be used:

(1) For each pollutant and its precursors, a single source impact analysis is sufficient to show compliance with standards and PSD increments if modeled impacts from emission increases equal to or greater than a significant emission rate above the netting basis due to the proposed source or modification being evaluated are less than the Class II Significant Air Quality Impact Levels specified in OAR 340-200-0020, Table 1.

(2) If the requirement in section (1) of this rule is not satisfied, the owner or operator of a proposed source or modification being evaluated must perform competing source modeling as follows:

(a) For demonstrating compliance with the PSD Increments (as defined in OAR 340-202-0210, Table 1), the owner or operator of a proposed source or modification must show that modeled impacts from the proposed increased emissions (above the modeled Baseline Concentration) plus Competing PSD Increment Consuming Source Impacts (above the modeled Baseline Concentration) are less than the PSD increments for all averaging times.

(b) For demonstrating compliance with the NAAQS, the owner or operator of a proposed source must show that the total modeled impacts plus total Competing NAAQS Source Impacts plus General Background Concentrations are less than the NAAQS for all averaging times.

(3) Additional Impact Modeling:

(a) When referred to this rule by divisions 222 or 224, the owner or operator of a source must provide an analysis of the impairment to visibility, soils and vegetation that would occur as a result of the source or modification, and general commercial, residential, industrial and other growth associated with the source or modification. As a part of this analysis, deposition modeling analysis is required for sources emitting heavy metals above the significant emission rates as defined in OAR 340-200-0020, Table 2. Concentration and deposition modeling may also be required for sources emitting other compounds on a case-by-case basis;

(b) The owner or operator must provide an analysis of the air quality concentration projected for the area as a result of general commercial, residential, industrial and other growth associated with the source or modification.

(4) Air Quality Monitoring:

(a)(A) When referred to this rule by division 224, the owner or operator of a source must submit with the application an analysis of ambient air quality in the area impacted by the proposed project. This analysis, which is subject to the Department’s approval, must be conducted for each pollutant potentially emitted at a significant emission rate by the proposed source or modification. The analysis must include continuous air quality monitoring data for any pollutant that may be emitted by the source or modification, except for volatile organic compounds. The data must relate to the year preceding receipt of the complete application and must have been gathered over the same time period. The Department may allow the owner or operator to demonstrate that data gathered over some other time period would be adequate to determine that the source or modification would not cause or contribute to a violation of an ambient air quality standard or any applicable pollutant increment. Pursuant to the requirements of these rules, the owner or operator must submit for the Department’s approval, a preconstruction air quality monitoring plan. This plan must be submitted in writing at least 60 days prior to the planned beginning of monitoring and approved in writing by the Department before monitoring begins.

(B) Required air quality monitoring must be conducted in accordance with 40 CFR 58 Appendix B, “Quality Assurance Requirements for Prevention of Significant Deterioration (PSD) Air Monitoring” (July 1, 2000) and with other methods on file with the Department.

(C) The Department may exempt the owner or operator of a proposed source or modification from preconstruction monitoring for a specific pollutant if the owner or operator demonstrates that the air quality impact from the emissions increase would be less than the amounts listed below or that modeled competing source concentration (plus General Background Concentration) of the pollutant within the Source Impact Area are less than the following significant monitoring concentrations:

(i) Carbon monoxide; 575 ug/m3, 8 hour average;

(ii) Nitrogen dioxide; 14 ug/m3, annual average;

(iii) PM10; 10 ug/m3, 24 hour average;

(iv) PM2.5; 4 ug/m3, 24-hour average;

(v) Sulfur dioxide; 13 ug/m3, 24 hour average;

(vi) Ozone; Any net increase of 100 tons/year or more of VOCs from a source or modification subject to PSD requires an ambient impact analysis, including the gathering of ambient air quality data. However, requirement for ambient air monitoring may be exempted if existing representative monitoring data shows maximum ozone concentrations are less than 50% of the ozone NAAQS based on a full season of monitoring;

(vii) Lead; 0.1 ug/m3, 24 hour average;

(viii) Fluorides; 0.25 ug/m3, 24 hour average;

(ix) Total reduced sulfur; 10 ug/m3, 1 hour average;

(x) Hydrogen sulfide; 0.04 ug/m3, 1 hour average;

(xi) Reduced sulfur compounds; 10 ug/m3, 1 hour average.

(D) The Department may allow the owner or operator of a source (where required by divisions 222 or 224) to substitute post construction monitoring for the requirements of (4)(a)(A) for a specific pollutant if the owner or operator demonstrates that the air quality impact from the emissions increase would not cause or contribute to an exceedance of any air quality standard. This analysis must meet the requirements of 340-225-0050(2)(b) and must use representative or conservative General Background Concentration data.

(E) When PM10 preconstruction monitoring is required by this section, at least four months of data must be collected, including the season(s) the Department judges to have the highest PM10 levels. PM10 must be measured in accordance with 40 CFR part 50, Appendix J (July 1, 1999). In some cases, a full year of data will be required.

(b) After construction has been completed, the Department may require ambient air quality monitoring as a permit condition to establish the effect of emissions, other than volatile organic compounds, on the air quality of any area that such emissions could affect.

Requirements for Demonstrating Compliance with Standards and Increments in PSD Class I Areas

For determining compliance with standards and increments in PSD Class I areas, the following methods must be used:

(1) Before January 1, 2003, the owner or operator of a source (where required by divisions 222 or 224) must model impacts and demonstrate compliance with standards and increments on all PSD Class I areas that may be affected by the source or modification.

(2) On or after January 1, 2003, the owner or operator of a source (where required by divisions 222 or 224) must meet the following requirements:

(a) For each pollutant and its precursors, a single source impact analysis will be sufficient to show compliance with increments if modeled impacts from emission increases equal to or greater than a significant emission rate above the netting basis due to the proposed source or modification being evaluated are demonstrated to be less than the Class I impact levels specified in OAR 340-200-0020, Table 1.

(b) If the requirement in subsection (a) of this section is not satisfied, the owner or operator must also show that the increased source impacts (above Baseline Concentration) plus Competing PSD Increment Consuming Source Impacts are less than the PSD increments for all averaging times.

(c) For each pollutant and its precursors, a single source impact analysis will be sufficient to show compliance with standards if modeled impacts from emission increases equal to or greater than a significant emission rate above the netting basis due to the proposed source or modification being evaluated are demonstrated to be less than the Class II impact levels specified in OAR 340-200-0020, Table 1.

(d) If the requirement of subsection (2)(a) of this section is not satisfied, and background monitoring data for each PSD Class I area shows that the NAAQS is more controlling than the PSD increment then the source must also demonstrate compliance with the NAAQS by showing that their total modeled impacts plus total modeled Competing NAAQS Source Impacts plus General Background Concentrations are less than the NAAQS for all averaging times.

Requirements for Demonstrating a Net Air Quality Benefit

Demonstrations of net air quality benefit for offsets must include the following:

(1) Ozone areas (VOC and NOx emissions). For sources capable of impacting a designated ozone nonattainment or maintenance area;

(a) Offsets for VOC and NOx are required if the source will be located within the designated area or within the Ozone Precursor Distance.

(b) The amount and location of offsets must be determined in accordance with this subsection:

(A)For new or modified sources locating within a designated nonattainment area, the offset ratio is 1.1:1. These offsets must come from within either the same designated nonattainment area as the new or modified source or another ozone nonattainment area (with equal or higher nonattainment classification) that contributes to a violation of the NAAQS in the same designated nonattainment area as the new or modified source.

(B) For new or modified sources locating within a designated maintenance area, the offset ratio is 1.1:1. These offsets may come from within either the designated area or the ozone precursor distance.

(C) For new or modified sources locating outside the designated area, but within the ozone precursor distance, the offset ratio is 1:1. These offsets may come from within either the designated area or the ozone precursor distance.

(D) Offsets from outside the designated area but within the Ozone Precursor Distance must be from sources affecting the designated area in a comparable manner to the proposed emissions increase. Methods for determining offsets are described in the Ozone Precursor Offsets definition (OAR 340-225-0020(11)).

(c) In lieu of obtaining offsets, the owner or operator may obtain an allocation at the rate of 1:1 from a growth allowance, if available, in an applicable maintenance plan.

(d) Sources within or affecting the Medford Ozone Maintenance Area are exempt from the requirement for NOx offsets relating to ozone formation.

(e) Sources within or affecting the Salem Ozone Maintenance Area are exempt from the requirement for VOC and NOx offsets relating to ozone formation.

(2) Non-Ozone areas (PM2.5, PM10, SO2, CO, NOx, and Lead emissions):

(a) For a source locating within a designated nonattainment area, the owner or operator must comply with paragraphs (A) through (E) of this subsection:

(A) Obtain offsets from within the same designated nonattainment area for the nonattainment pollutant(s);

(B) Except as provided in paragraph (C) of this subsection, provide a minimum of 1:1 offsets for each nonattainment pollutant and precursor with emission increases over the Netting Basis;

(i) 1 ton of direct PM2.5 may be used to offset 40 tons of SO2;

(ii) 1 ton of direct PM2.5 may be used to offset 100 tons of NOx;

(iii) 40 tons of SO2 may be used to offset 1 ton of direct PM2.5;

(iv) 100 tons of NOx may be used to offset 1 ton of direct PM2.5.

(D) Provide a net air quality benefit within the designated nonattainment area. “Net Air Quality Benefit” means:

(i) Offsets obtained result in a reduction in concentration at a majority of the modeled receptors and the emission increases from the proposed source or modification will result in less than a significant impact level increase at all modeled receptors; or

(ii) For a small scale local energy project and any infrastructure related to that project located in the same area, a reduction of the nonattainment pollutant emissions equal to the ratio specified in this subsection, provided that the proposed major source or major modification would not cause or contribute to a violation of the national ambient air quality standard or otherwise pose a material threat to compliance with air quality standards in the nonattainment area.

(E) Provide offsets sufficient to demonstrate reasonable further progress toward achieving the NAAQS.

(b) For a source locating outside a designated nonattainment area but causing a significant air quality impact on the area, the owner or operator must provide offsets sufficient to reduce the modeled impacts below the significant air quality impact level (OAR 340-200-0020) at all receptors within the designated nonattainment area. These offsets may come from within or outside the designated nonattainment area.

(c) For a source locating inside or causing a significant air quality impact on a designated maintenance area, the owner or operator must either provide offsets sufficient to reduce modeled impacts below the significant air quality impact level (OAR 340-200-0020) at all receptors within the designated maintenance area or obtain an allocation from an available growth allowance as allowed by an applicable maintenance plan. These offsets may come from within or outside the designated maintenance area.

(A) Medford-Ashland AQMA: Proposed new major PM10 sources or major PM10 modifications locating within the AQMA that are required to provide emission offsets under OAR 340-224-0060(2)(a) must provide reductions in PM10 emissions equal to 1.2 times the emissions increase over the netting basis from the new or modified source, and must provide a net air quality benefit within the AQMA. “Net Air Quality Benefit” means:

(i) A reduction in concentration at a majority of the modeled receptors and less than a significant impact level increase at all modeled receptors; or

(ii) For a small scale local energy project and any infrastructure related to that project located in the same area, a reduction of the maintenance pollutant emissions equal to the ratio specified in this paragraph, provided that the proposed major source or major modification would not cause or contribute to a violation of the national ambient air quality standard or otherwise pose a material threat to compliance with air quality standards in the maintenance area.

(B) Medford-Ashland AQMA: Proposed new major PM10 sources or major PM10 modifications located outside the Medford-Ashland AQMA that cause a significant air quality impact on the AQMA must provide reductions in PM10 emissions sufficient to reduce modeled impacts below the significant air quality impact level (OAR 340-200-0020) at all receptors within the AQMA.

(3) Except as provided in paragraph (2)(a)(C) of this rule, the emission reductions used as offsets must be of the same type of pollutant as the emissions from the new source or modification. Sources of PM10 must be offset with particulate in the same size range.

(4) The emission reductions used as offsets must be contemporaneous, that is, the reductions must take effect before the time of startup but not more than two years before the submittal of a complete permit application for the new source or modification. This time limitation may be extended through banking, as provided for in OAR 340 division 268, Emission Reduction Credit Banking. In the case of replacement facilities, the Department may allow simultaneous operation of the old and new facilities during the startup period of the new facility, if net emissions are not increased during that time period. Any emission reductions must be federally enforceable at the time of the issuance of the permit.

(5) Offsets required under this rule must meet the requirements of Emissions Reduction Credits in OAR 340 division 268.

(6) Emission reductions used as offsets must be equivalent in terms of short term, seasonal, and yearly time periods to mitigate the effects of the proposed emissions.

NOTE: This rule is included in the State of Oregon Clean Air Act Implementation Plan as adopted by the EQC under OAR 340-200-0040.
