(2)“Applicable implementation plan” or “applicable SIP” means the portion (or portions) of the applicable SIP or most recent revision thereof, which has been approved under Section 110 of the Act, or promulgated under Section 110(c) of the Act (Federal implementation plan), or promulgated under Section 301(d) of the Act which implements the relevant requirements of the Act.
(3)“Areawide air quality modeling analysis” means an assessment on a scale that includes the entire nonattainment area or maintenance area which uses an air quality dispersion model to determine the effects of emissions on air quality.
(4)“Cause or contribute to any new violation of any standard in any area” means a federal action that:
(a)Causes a new violation of a NAAQS at a location in a nonattainment area or maintenance area which would otherwise not be in violation of the standard during the future period in question if the federal action were not taken; or
(b)Contributes, in conjunction with other reasonably foreseeable actions, to a new violation of a NAAQS at a location in a nonattainment area or maintenance area in a manner that would increase the frequency or severity of the new violation.
(5)“Caused by”, as used in the terms “direct emissions” and “indirect emissions,” means emissions that would not otherwise occur in the absence of the federal action.
(6)“Criteria pollutant” means any pollutant for which there is established a NAAQS at 40 CFR part 50 (July 1, 1994).
(7)“Direct emissions” means those emissions of a criteria pollutant or precursors of a criteria pollutant that are caused or initiated by the federal action and occur at the same time and place as the action.
(8)“Emergency” means a situation where extremely quick action on the part of the Federal agencies involved is needed and where the timing of such federal activities makes it impractical to meet the requirements of this division, such as natural disasters like hurricanes or earthquakes, civil disturbances such as terrorist acts, and military mobilizations.
(9)“Emissions budgets” means those portions of the applicable SIP’s projected emissions inventories that describe levels of emissions (mobile, stationary, area, etc.) that provide for meeting reasonable further progress milestones, attainment, or maintenance for any criteria pollutant or precursors of a criteria pollutant.
(10)“Emissions offsets”, for purposes of OAR 340-250-0080 (Criteria for Determining Conformity of General Federal Actions), means emissions reductions which are quantifiable, consistent with OAR 340 division 268 and 340-224-0090, and the applicable SIP attainment and reasonable further progress demonstrations, surplus to reductions required by, and credited to, other SIP provisions, enforceable at both the state and federal levels, and permanent within the timeframe specified by the program.
(11)“Emissions that a federal agency has a continuing program responsibility for” means emissions that are specifically caused by an agency carrying out its authorities, and does not include emissions that occur due to subsequent activities, unless such activities are required by the federal agency. Where an agency, in performing its normal program responsibilities, takes actions itself or imposes conditions that result in air pollutant emissions by a nonfederal entity taking subsequent actions, such emissions are covered by the meaning of a continuing program responsibility.
(12)“EPA” means the United States Environmental Protection Agency.
(13)“Federal action” means any activity engaged in by a department, agency, or instrumentality of the federal government, or any activity that a department, agency or instrumentality of the federal government supports in any way, provides financial assistance for licenses, permits, or approves under title 23 U.S.C. or the Federal Transit Laws (49 U.S.C. Chapter 53). Where the federal action is a permit, license, or other approval for some aspect of a nonfederal undertaking, the relevant activity is the part, portion, or phase of the nonfederal undertaking that requires the federal permit, license, or approval.
(14)“Federal agency” means a federal department, agency, or instrumentality of the federal government.
(15)“Increase the frequency or severity of any existing violation of any standard in any area” means to cause a nonattainment area to exceed a standard more often or to cause a violation at a greater concentration than previously existed or would otherwise exist during the future period in question, if the project were not implemented.
(16)“Indirect emissions” means those emissions of a criteria pollutant or precursors of a criteria pollutant that:
(a)Are caused by the federal action, but may occur later in time or may be farther removed in distance from the action itself but are still reasonably foreseeable; and
(b)The federal agency can practicably control and will maintain control over due to a continuing program responsibility of the federal agency.
(17)“Local air quality modeling analysis” means an assessment of localized impacts on a scale smaller than the entire nonattainment area or maintenance area, including, for example, congested roadway intersections and highways or transit terminals, which uses an air quality dispersion model to determine the effects of emissions on air quality.
(18)“Maintenance area” means an area with a maintenance plan approved under Section 175A of the Act.
(19)“Maintenance plan” means a revision to the applicable SIP, meeting the requirements of Section 175A of the Act.
(20)“Metropolitan Planning Organization” or “MPO” means that organization designated as being responsible, together with the state, for conducting the continuing, cooperative, and comprehensive planning process under 23 U.S.C. 134 and 49 U.S.C. 1607.
(21)“Milestone” has the meaning given in Sections 182(g)(1) and 189(c)(1) of the Act.
(22)“National ambient air quality standards” or “NAAQS” means those standards established pursuant to Section 109 of the Act and include standards for carbon monoxide (CO), lead (Pb), nitrogen dioxide (NO2), ozone, particulate matter (PM10, PM 2.5), and sulfur dioxide (SO2).
(23)“NEPA” means the National Environmental Policy Act of 1969, as amended (42 U.S.C. 4321 et seq.).
(24)“Nonattainment area” means an area designated as nonattainment under Section 107 of the Act and described in 40 CFR part 81 (July 1, 1994).
(25)“Precursors of a criteria pollutant” means:
(a)For ozone, nitrogen oxides (NOx), unless an area is exempted from NOx requirements under Section 182(f) of the Act, and volatile organic compounds (VOC); and
(b)For PM10, those pollutants described in the PM10 nonattainment area applicable SIP as significant contributors to the PM10 levels.
(26)“Reasonably foreseeable emissions” means projected future indirect emissions that are identified at the time the conformity determination is made; the location of such emissions is known and the emissions are quantifiable, as described and documented by the federal agency based on its own information and after reviewing any information presented to the federal agency.
(27)“Regional water or wastewater projects” include construction, operation, and maintenance of water or wastewater treatment facilities, and water storage reservoirs which affect a large portion of a nonattainment area or maintenance area.
(28)“Regionally significant action” means a federal action for which the direct emissions and indirect emissions of any pollutant represent 10 percent or more of a nonattainment area’s or maintenance area’s emissions inventory for that pollutant.
(29)“Total of direct and indirect emissions” means the sum of direct emissions and indirect emissions increases and decreases caused by the federal action; i.e., the “net” emissions considering all direct emissions and indirect emissions. The portion of emissions which are exempt or presumed to conform under OAR 340-250-0020 (Applicability)(4), (5), (6) or (7) are not included in the “total of direct and indirect emissions.”
