Section III-1410 - Criteria for Determining Conformity of General Federal Actions

A. An action required under LAC 33:III.1405 to have a conformity determination for a specific pollutant will be determined to conform to the applicable SIP if, for each pollutant that equals or exceeds the rates in LAC 33:III.1405.B or otherwise requires a conformity determination due to the total of direct and indirect emissions from the action, the action meets the requirements of Subsection C of this Section and meets any of the following requirements:

1. for any criteria pollutant, the total of direct and indirect emissions from the action are specifically identified and accounted for in the applicable SIP's attainment or maintenance demonstration;

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 SIP or a measure similarly enforceable under state and federal law that effects emission offsets so that there is no net increase in emissions of that pollutant;

3. for any criteria pollutant, except ozone and nitrogen dioxide, the total of direct and indirect emissions from the action meet the requirements:

a. specified in Subsection B of this Section, based on areawide air quality modeling analysis and local air quality modeling analysis; or

b. meet the requirements of Paragraph A.5 of this Section and, for local air quality modeling analysis, the requirement of Subsection B of this Section;

4. for CO or PM₁₀:

a. where the department determines that an areawide air quality modeling analysis is not needed, the total of direct and indirect emissions from the action meet the requirements specified in Subsection B of this Section based on local air quality modeling analysis; or

b. where the department determines 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 meet the requirements specified in Subsection B of this Section based on areawide modeling or meet the requirements of Paragraph A.5 of this Section; or

5. for ozone or nitrogen dioxide and for purposes of Subparagraphs A.3.b and 4.b of this Section, each portion of the action or the action as a whole meets any of the following requirements:

a. where EPA has approved a revision to an area's attainment or maintenance demonstration after 1990 and the department makes a determination as provided in Clause A.5.a.i of this Section or where the state makes a commitment as provided in Clause A.5.a.ii of this Section:

i. 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 that, together with all other emissions in the nonattainment or maintenance area, would not exceed the emissions budgets specified in the applicable SIP. As a matter of policy, should the department make such determination or commitment, the federal agency must provide to the Office of Environmental Assessment information on all known projects or other actions that may affect air quality or emissions in any area to which this rule is applicable, regardless of whether such project or action is determined to be subject to this rule under LAC 33:III.1405. The department may charge the federal agency requesting such determination a reasonable fee based on the number of man-hours required to perform and document the determination; or

ii. 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 SIP and the governor or the governor's designee for SIP actions makes a written commitment to EPA which includes the following:

(a). a specific schedule for adoption and submittal of a SIP revision which provides that the needed emission offsets would be achieved prior to the time emissions from the federal action would occur;

(b). identification of specific measures for incorporation into the SIP 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 SIP;

(c). a demonstration that all existing applicable SIP 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, such as mitigation measures available through the SIP regulating banking of emission credits; and

(e). written documentation including all air quality analyses supporting the conformity determination;

iii. where a federal agency made a conformity determination based on a state commitment under Clause A.5.a.ii of this Section, such a state commitment is automatically deemed a call for a SIP revision by EPA under Section 110(k)(5) of the CAA, 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 SIP;

b. the action (or portion thereof), as determined by the MPO, is specifically included in a current transportation plan and transportation improvement program which have been found to conform to the applicable SIP under LAC 33:III.Chapter 14.Subchapter B, or 40 CFR Part 93, Subpart A;

c. emissions from the action (or portion thereof) are fully offset within the same nonattainment or maintenance area through a revision to the applicable SIP or an equally enforceable measure that effects emission offsets 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;

d. where EPA has not approved a revision to the relevant SIP attainment or maintenance demonstration since 1990, the total of direct and indirect emissions from the action for the future years [described in LAC 33:III.1411.D] do not increase emissions with respect to the baseline emissions and the baseline emissions:

i. reflect the historical activity levels that occurred in the geographic area affected by the proposed federal action during:

(a). calendar year 1990;

(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 associated with emissions), if a classification is promulgated in 40 CFR Part 81 ; or

(c). the year of the baseline inventory in the applicable PM₁₀ SIP;

ii. are the total of direct and indirect emissions calculated for the future years [described in LAC 33:III.1411.D] using the historic activity levels [described in Clause A.5.d.i of this Section] and appropriate emission factors for the future years; or

e. where the action involves regional water and/or wastewater projects, such projects are sized to meet only the needs of population projections that are in the applicable SIP.

B. The areawide and/or local air quality modeling analyses must:

1. meet the requirements in LAC 33:III.1411; and

2. show that the action does not:

a. cause or contribute to any new violation of any standard in any area; or

b. increase the frequency or severity of any existing violation of any standard in any area.

C. Notwithstanding any other requirements of this Section, an action subject to this Subchapter may not be determined to conform to the applicable SIP unless the total of direct and indirect emissions from the action is in compliance or consistent with all relevant requirements and milestones contained in the applicable SIP, such as elements identified as part of the reasonable further progress schedules, assumptions specified in the attainment or maintenance demonstration, prohibitions, numerical emission limits, and work practice requirements.

D. Any analyses required under this Section must be completed and any mitigation requirements necessary for a finding of conformity must be identified and committed to in compliance with LAC 33:III.1412.B and F before the determination of conformity is made.
