par. (a) or
(b):
NR 489.03(7)(a)
(a) The federal agency shall clearly demonstrate using methods consistent with this chapter that the total of direct and indirect emissions from the type of activities which would be presumed to conform would not:
NR 489.03(7)(a)1.
1. Cause or contribute to any new violation of any NAAQS in any area;
NR 489.03(7)(a)2.
2. Interfere with provisions in the applicable implementation plan for maintenance of any NAAQS;

sub. (2), but represents 10% or more of a nonattainment or maintenance area's total emissions of that pollutant, the action is defined as a regionally significant action and the requirements of
ss. NR 489.01 and
489.05 to
489.10 shall apply for the federal action.
NR 489.03(10)
(10) Where an action presumed to be de minimis under

NR 489.07
Frequency of conformity determinations. NR 489.07(1)(1) The conformity status of a federal action automatically lapses 5 years after the date a final conformity determination is reported under
s. NR 489.05, unless the federal action has been completed or a continuous program has been commenced to implement that federal action within a reasonable time.
NR 489.07(2)
(2) Ongoing federal activities at a given site showing continuous progress are not new actions and do not require periodic redeterminations so long as the emissions associated with such activities are within the scope of the final conformity determination reported under
s. NR 489.05.
NR 489.07(3)
(3) If, after the conformity determination is made, the federal action is changed so that there is an increase in the total of direct and indirect emissions above the levels in
s. NR 489.03 (2), a new conformity determination is required.

Criteria for determining conformity of general federal actions. An action required under
s. NR 489.03 to have a conformity determination for a specific pollutant will be determined to conform to the applicable implementation plan if, for each pollutant that exceeds the rates in
s. NR 489.03 (2), or otherwise requires a conformity determination due to the total of direct and indirect emissions from the action, the action meets the requirements of
s. NR 489.085 (2), and meets any of the following requirements:
NR 489.08(1)
(1) For any criteria pollutant, the total of direct and indirect emissions from the action are specifically identified and accounted for in the applicable implementation plan's attainment or maintenance demonstration;
NR 489.08(2)
(2) For ozone or nitrogen dioxide, the total of direct and indirect emissions from the action are fully offset within the same nonattainment or maintenance area through a revision to the applicable implementation plan or a measure similarly enforceable under state and federal law that effects emission reductions so that there is no net increase in emissions of that pollutant;
NR 489.08(3)
(3) For any criteria pollutant, except ozone and nitrogen dioxide, the total of direct and indirect emissions from the action meets:
NR 489.08(3)(a)
(a) The requirements specified in
s. NR 489.085 (1), based on areawide air quality modeling analysis and local air quality modeling analysis; or
NR 489.08(4)(a)
(a) Where the department determines, in accordance with
ss. NR 489.05 and
489.06 and consistent with the applicable implementation plan, that an areawide air quality modeling analysis is not needed, the total of direct and indirect emissions from the action meets the requirements specified in
s. NR 489.085 (1), based on local air quality modeling analysis; or
NR 489.08(4)(b)
(b) Where the department determines, in accordance with
ss. NR 489.05 and
489.06 and consistent with the applicable implementation plan, that an areawide air quality modeling analysis is appropriate and that a local air quality modeling analysis is not needed, the total of direct and indirect emissions from the action meets the requirements specified in
s. NR 489.085 (1), based on areawide modeling, or meets the requirements of
sub. (5); or
NR 489.08(5)
(5) For ozone or nitrogen dioxide, and for purposes of
subs. (3) (b) and
(4) (b), each portion of the action or the action as a whole meets any of the following requirements:
NR 489.08(5)(a)
(a) Where EPA has approved a revision to an area's attainment or maintenance demonstration after 1990 and the state makes a determination as provided in
subd. 1. or where the state makes a commitment as provided in
subd. 2.:
NR 489.08 Note
Note: Any such determination or commitment shall be made in compliance with ss.
NR 489.05 and
489.06.
NR 489.08(5)(a)1.
1. The total of direct and indirect emissions from the action, or portion thereof, is determined and documented by the department to result in a level of emissions which, together with all other emissions in the nonattainment or maintenance area, would not exceed the emissions budgets specified in the applicable implementation plan.
NR 489.08(5)(a)2.
2. The total of direct and indirect emissions from the action, or portion thereof, is determined by the department to result in a level of emissions which, together with all other emissions in the nonattainment or maintenance area, would exceed an emissions budget specified in the applicable implementation plan and the department makes a written commitment to EPA which includes the following:
NR 489.08(5)(a)2.a.

NR 489.08(5)(a)2.b.
b. Identification of specific measures for incorporation into the applicable implementation plan which would result in a level of emissions which, together with all other emissions in the nonattainment or maintenance area, would not exceed any emissions budget specified in the applicable implementation plan;
NR 489.08(5)(a)2.c.
c. A demonstration that all existing applicable implementation plan requirements are being implemented in the area for the pollutants affected by the federal action, and that local authority to implement additional requirements has been fully pursued;

d. A determination that the responsible federal agencies have required all reasonable mitigation measures associated with their action; and
NR 489.08(5)(a)2.e.
e. Written documentation including all air quality analyses supporting the conformity determination.
NR 489.08 Note
Note: When a federal agency makes a conformity determination based on a state commitment under subd. 2.., such a state commitment is automatically deemed a call for an implementation plan revision by EPA under section 110 (k) (5) of the act (
42 USC 7410 (k) (5)), effective on the date of the federal conformity determination and requiring response within 18 months or any shorter time within which the state commits to revise the applicable implementation plan.
NR 489.08(5)(b)
(b) The action, or portion thereof, as determined by the MPO, is specifically included in a current transportation plan and transportation improvement program which has been found to conform to the applicable implementation plan under
40 CFR part 51, subpart T or part 93, subpart A as in effect on July 1, 1998;
NR 489.08(5)(c)
(c) The action, or portion thereof, fully offsets its emissions within the same nonattainment or maintenance area through a revision to the applicable implementation plan or an equally enforceable measure that achieves emission reductions equal to or greater than the total of direct and indirect emissions from the action so that there is no net increase in emissions of that pollutant;
NR 489.08(5)(d)
(d) Where EPA has not approved a revision to the relevant implementation plan attainment or maintenance demonstration since 1990, the total of direct and indirect emissions from the action for the future years, described in
s. NR 489.09 (4), do not increase emissions with respect to the baseline emissions, and:
NR 489.08(5)(d)1.
1. The baseline emissions reflect the historical activity levels that occurred in the geographic area affected by the proposed federal action during:
NR 489.08(5)(d)1.b.
b. The calendar year that is the basis for the classification or, where the classification is based on multiple years, the year that is most representative in terms of the level of activity, if a classification is promulgated in
40 CFR part 81 as in effect on July 1, 1998; or
NR 489.08(5)(d)1.c.
c. The year of the baseline inventory in the PM
10 applicable implementation plan; and
NR 489.08(5)(d)2.
2. The baseline emissions are the total of direct and indirect emissions calculated for the future years, described in
s. NR 489.09 (4), using the historic activity levels, described in
subd. 1., and appropriate emission factors for the future years; or
NR 489.08(5)(e)
(e) Where the action involves regional water or wastewater projects, the projects are sized to meet only the needs of population projections that are in the applicable implementation plan, based on assumptions regarding per capita use that are developed or approved in accordance with

Procedures for conformity determinations of general federal actions. NR 489.09(1)
(1) The analyses required under this chapter shall be based on the latest planning assumptions.
NR 489.09(1)(a)
(a) All planning assumptions, including, but not limited to, per capita water and sewer use, vehicle miles traveled per capita or per household, trip generation per household, vehicle occupancy, household size, vehicle fleet mix, vehicle ownership, wood stoves per household, and the geographic distribution of population growth, shall be derived from the estimates of current and future population, employment, travel and congestion most recently developed by the MPO, or other agency authorized to make such estimates for the area. The conformity determination shall also be based on assumptions and estimates about current and future background concentrations that are included in the current applicable implementation plan and based on the latest assumptions and estimates about other federal actions.
NR 489.09(1)(b)
(b) Any revisions to these estimates used as part of the conformity determination, including projected shifts in geographic location or level of population, employment, travel and congestion, shall be approved by the MPO or other agency authorized to make such estimates for the area.
NR 489.09(2)
(2) The analyses required under this chapter shall be based on the latest and most accurate emission estimation techniques available as described below, unless such techniques are inappropriate. If such techniques are inappropriate and written approval of the EPA regional administrator is obtained for any modification or substitution, they may be modified or another technique substituted on a case-by-case basis or, where appropriate, on a generic basis for a specific federal agency program.
NR 489.09(2)(a)
(a) For motor vehicle emissions, the most current version of the motor vehicle emissions model specified by EPA for use in the preparation or revision of implementation plans in the state or area shall be used for the conformity analysis as specified below in
subds. 1. and
2.:
NR 489.09(2)(a)1.
1. A new motor vehicle emissions model shall be used after EPA publishes in the federal register a notice of its availability.
NR 489.09(2)(a)2.
2. A grace period of 3 months shall apply during which the motor vehicle emissions model previously specified by EPA as the most current version may be used. Conformity analyses for which the analysis was begun during the grace period or no more than 3 years before the federal register notice of availability of the latest emission model may continue to use the previous version of the model specified by EPA, if a final determination as to conformity is made within 3 years of such analysis.
