“Applicable implementation plan" means the portion, or portions, of the state implementation plan, or most recent revision thereof, which has been approved under section 110 of the act (42 USC 7410
), a federal implementation plan promulgated under section 110 (c) of the act (42 USC 7410 (c)
), or a tribal implementation plan promulgated or approved pursuant to regulations promulgated under section 301 (d) of the act (42 USC 7601 (d)
) and which implements the relevant requirements of the act.
“Areawide air quality modeling analysis" means an assessment on a scale that includes the entire nonattainment or maintenance area which uses an air quality dispersion model to determine the effects of emissions on air quality.
“Cause or contribute to a new violation" means a federal action that:
Causes a new violation of a national ambient air quality standard (NAAQS) at a location in a nonattainment 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
Contributes, in conjunction with other reasonably foreseeable actions, to a new violation of a NAAQS at a location in a nonattainment or maintenance area in a manner that would increase the frequency or severity of the new violation.
“Caused by", as used in conjunction with the terms “direct emissions" and “indirect emissions", means emissions that would not otherwise occur in the absence of the federal action.
“Criteria pollutant" means any pollutant for which there is established a NAAQS under 40 CFR part 50
as in effect on July 1, 1998.
“Direct emissions" means those emissions of a criteria pollutant or its precursors that are caused or initiated by the federal action and occur at the same time and place as the action.
“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 chapter, such as natural disasters like hurricanes or earthquakes, civil disturbances such as terrorist acts, and military mobilizations.
“Emissions budgets" are those portions of the total allowable emissions defined in an EPA-approved revision to the applicable implementation plan for a certain date for the purpose of meeting reasonable further progress milestones or attainment or maintenance demonstrations, for any criteria pollutant or its precursors, specifically allocated by the applicable implementation plan to mobile sources, to any stationary source or class of stationary sources, to any federal action or class of action, to any class of area sources, or to any subcategory of the emissions inventory. The allocation system shall be specific enough to assure meeting the criteria of section 176 (c) (1) (B) of the act (42 USC 7506 (c) (1) (B)
). An emissions budget may be expressed in terms of an annual period, a daily period, or other period established in the applicable implementation plan.
“Emissions offsets", for purposes of s. NR 489.08
, are emission reductions which are quantifiable, consistent with the attainment and reasonable further progress demonstrations of the applicable implementation plan, surplus to reductions required by, and credited to, other applicable implementation plan provisions, enforceable under both state and federal law, and permanent within the time frame specified by the program. Emissions reductions intended to be achieved as emissions offsets under this chapter shall be monitored and enforced in a manner equivalent to that under EPA's new source review requirements.
“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 non-federal entity taking subsequent actions, such emissions are covered by the meaning of a continuing program responsibility.
“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, other than activities related to transportation plans, programs and projects developed, funded or approved under title 23 USC
or the federal transit act (49 USC 1601

“Federal agency" means, for purposes of this chapter, a federal department, agency or instrumentality of the federal government.
“Increase the frequency or severity of any existing violation of any standard in any area" means to cause a nonattainment area to exceed a NAAQS 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.
“Indirect emissions" means those emissions of a criteria pollutant or its precursors that:
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
The federal agency can practicably control and will maintain control over due to a continuing program responsibility of the federal agency, including, but not limited to:
Traffic on or to, or stimulated or accommodated by, a proposed facility which is related to increases or other changes in the scale or timing of operations of the facility;
Emissions related to the activities of employes of contractors or federal employes;
Emissions related to employe commuting and similar programs to increase average vehicle occupancy imposed on all employers of a certain size in the locality;
Emissions related to the use of federal facilities under lease or temporary permit;
Emissions related to the activities of contractors or leaseholders that may be addressed by provisions that are usual and customary for contracts or leases or within the scope of contractual protection of the interests of the United States.

“Reasonably foreseeable emissions" are projected future indirect emissions that are identified at the time the conformity determination is made, where the location of such emissions is known to the extent adequate to determine the impact of such emissions, 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.
“Regionally significant action" means a federal action for which the direct and indirect emissions of any pollutant represent 10% or more of a nonattainment or maintenance area's emissions inventory for that pollutant.
“Regional water or wastewater projects" include construction, operation and maintenance of water or wastewater conveyances, water or wastewater treatment facilities, and water storage reservoirs which affect a large portion of a nonattainment or maintenance area.
“Total of direct and indirect emissions" means the sum of direct and indirect emissions increases and decreases caused by the federal action, i.e., the net emissions considering all direct and indirect emissions. Any emissions decreases used to reduce the total shall be enforceable under federal law. The portion of emissions which are exempt or presumed to conform under s. NR 489.03 (3)
are not included in the total of direct and indirect emissions, except as provided in s. NR 489.03 (10)
. The total of direct and indirect emissions includes emissions of criteria pollutants and emissions of precursors of criteria pollutants. The segmentation of projects for conformity analyses when emissions are reasonably foreseeable is not permitted by this chapter.
