Virginia Law

A. The provisions of this chapter shall apply to the following actions:

1. Except as provided for in subsection C of this section or 40 CFR 93.126, conformity determinations are required for:

a. The adoption, acceptance, approval, or support of transportation plans and transportation plan amendments developed pursuant to 23 CFR Part 450 or 49 CFR Part 613 by a MPO or USDOT;

b. The adoption, acceptance, approval, or support of TIPs and TIP amendments developed pursuant to 23 CFR Part 450 or 49 CFR Part 613 by a MPO or USDOT; and

c. The approval, funding, or implementation of FHWA/FTA projects.

2. Conformity determinations are not required under this chapter for individual projects that are not FHWA/FTA projects. However, 40 CFR 93.121 applies to the projects if they are regionally significant.

3. This chapter shall apply to conformity determinations for which the final decision is made on or after the program approval date. For purposes of applying this subdivision, the program approval date of the regulation adopted by the board on March 26, 2007, shall be the date 30 days after the date on which a notice is published in the Virginia Register acknowledging that the administrator has approved the regulation adopted by the board on March 26, 2007.

B. The provisions of this chapter shall apply in all nonattainment and maintenance areas for transportation-related criteria pollutants for which the area is designated nonattainment or has a maintenance plan.

1. The provisions of this chapter apply with respect to emissions of the following criteria pollutants: ozone, carbon monoxide (CO), nitrogen dioxide (NO₂), particles with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM₁₀); and particles with an aerodynamic diameter less than or equal to a nominal 2.5 micrometers (PM_2.5).

2. The provisions of this chapter also apply with respect to emissions of the following precursor pollutants:

a. Volatile organic compounds (VOCs) and nitrogen oxides (NO_X) in ozone areas;

b. NO_X in nitrogen dioxide areas;

c. VOCs or NO_X or both, in PM₁₀ areas:

(1) If the EPA Regional Administrator or the DEQ Director has made a finding that transportation-related emissions of one or both of these precursors within the nonattainment area are a significant contributor to the PM₁₀ nonattainment problem and has so notified the MPO and USDOT; or

(2) If the applicable implementation plan (or implementation plan submission) establishes an approved (or adequate) budget for such emissions as part of the reasonable further progress, attainment or maintenance strategy;

d. NO_X in PM_2.5 areas:

(1) Unless both the EPA Regional Administrator and the DEQ Director have made a finding that transportation-related emissions of NO_X within the nonattainment area are not a significant contributor to the PM_2.5 nonattainment problem and have so notified the MPO and USDOT; or

(2) The applicable implementation plan (or implementation plan submission) does not establish an approved (or adequate) budget for such emissions as part of the reasonable further progress, attainment or maintenance strategy; and

e. VOC, sulfur dioxide (S0₂) and/or ammonia (NH₃) in PM_2.5 areas either:

(1) If the EPA Regional Administrator or the DEQ Director has made a finding that transportation-related emissions of any of these precursors within the nonattainment area are a significant contributor to the PM_2.5 nonattainment problem and has so notified the MPO and USDOT; or

(2) If the applicable implementation plan (or implementation plan submission) establishes an approved (or adequate) budget for such emissions as part of the reasonable further progress, attainment or maintenance strategy.

3. The provisions of this chapter apply to PM_2.5 nonattainment and maintenance areas with respect to PM_2.5 from re-entrained road dust if the EPA Regional Administrator or the DEQ Director has made a finding that re-entrained road dust emissions within the area are a significant contributor to the PM_2.5 nonattainment problem and has so notified the MPO and USDOT, or if the applicable implementation plan (or implementation plan submission) includes re-entrained road dust in the approved (or adequate) budget as part of the reasonable further progress, attainment or maintenance strategy. Re-entrained road dust emissions are produced by travel on paved and unpaved roads (including emissions from anti-skid and deicing materials).

4. The provisions of this chapter apply to maintenance areas through the last year of the area's maintenance plan approved under § 175A(b) of the federal Clean Air Act, unless the applicable implementation plan specifies that the provisions of this chapter shall apply for more than 20 years.

C. In order to receive any FHWA/FTA approved or funding actions, including NEPA approvals, for a project phase subject to this chapter, a currently conforming transportation plan and TIP must be in place at the time of project approval as described in 40 CFR 93.114, except as provided by 40 CFR 93.114(b).

D. For areas or portions of areas that have been continuously designated attainment or not designated for any National Ambient Air Quality Standard for ozone, CO, PM₁₀, PM_2.5 or NO₂ since 1990 and are subsequently redesignated to nonattainment or designated nonattainment for any National Ambient Air Quality Standard for any of these pollutants, the provisions of this chapter shall not apply with respect to that National Ambient Air Quality Standard for 12 months following the effective date of final designation to nonattainment for each National Ambient Air Quality Standard for such pollutant.
