      2. (b) transportation system improvements using intelligent transportation system (ITS) technologies that affect regional travel on a daily or routinely recurring interval;
   5. (v) air quality or emissions impact. Any transportation project that the commissioner of the department identifies, after consultation with NYSDOT and the affected MPO, as having the potential to affect air quality on a regional basis.
2. (2) Affected MPOs and NYSDOT shall, in consultation with the department, determine which minor arterials and transit projects, if any, have the principal purpose of serving regional transportation needs. Such minor arterials and transportation projects shall be included in the regional emissions analysis as required in this Part.
3. (3) The MPO shall, in consultation with the department and NYSDOT, determine which projects, based on information provided by the project sponsor, have undergone a significant change in design concept and scope from the MPO transportation plan and MPO TIP.
4. (4) NYSDOT shall, in consultation with the appropriate affected local transportation and air agencies, make the determinations required under paragraphs (1)-(3) of this subdivision for arterials and projects in nonattainment and maintenance areas outside MPO boundaries.

5. (5) In the event that the department, NYSDOT, and the affected MPOs cannot reach agreement as to which projects are regionally significant, the matter shall be resolved in accordance with the procedures in section 240-2.9 of this Subpart.

   (c) Procedures for the evaluation of certain exempt projects.

6. (1) The affected MPOs and NYSDOT shall, in consultation with the department, determine which exempt projects under 40 CFR 93.126 (see Table 1, section 200.9 of this Title) and 40 CFR 93.127 (see Table 1, section 200.9 of this Title) should be treated as non-exempt due to significant emissions impacts.

7. (2) NYSDOT shall, in consultation with the department and affected local air and transportation agencies, make the determination required under paragraph (1) of this subdivision for projects in nonattainment and maintenance areas outside MPO boundaries.

   (d) Timely TCM implementation.

8. (1) NYSDOT, the department, and the affected MPOs shall cooperatively determine:

   1. (i) whether TCMs specifically identified in the applicable SIP revision are being implemented as scheduled;
   2. (ii) whether State and local agencies with the appropriate authority are giving maximum priority, consistent with 40 CFR 93.113 (see Table 1, section 200.9 of this Title), to approving or funding of TCMs specifically identified in the applicable SIP revision; and

   3. (iii) whether delays in implementing TCMs specifically identified in the applicable SIP necessitate revision of the SIP.

      (e) Procedures for projects in PM₁₀ and/or PM_2.5 nonattainment area.

9. (1) The lead conformity agency shall determine through interagency consultation if projects located in PM₁₀ and/or PM_2.5 nonattainment areas require a quantitative PM₁₀ and/or PM_2.5 hot-spot analysis in accordance with 40 CFR 93.123(b)(1) (see Table 1, section 200.9 of this Title).

(f) Procedures for notification of MPO transportation plan or MPO TIP amendments adding or deleting only exempt projects.

1. (1) Each affected MPO shall determine, in consultation with NYSDOT, whether MPO TIP or MPO transportation plan amendments solely concern the addition or deletion of exempt projects listed in 40 CFR 93.126 (see Table 1, section 200.9 of this Title) and 40 CFR 93.127 (see Table 1, section 200.9 of this Title).
2. (2) NYSDOT shall make the determination required under paragraph (1) of this subdivision for projects outside MPO boundaries in nonattainment or maintenance areas.
3. (3) The department, NYSDOT, USDOT, EPA and, as appropriate, affected local air and transportation agencies, shall be notified in writing of any determinations made pursuant to this subdivision within 30 days of such determination.

(h) Procedures for transportation activities crossing MPO or nonattainment areas boundaries. NYSDOT, in consultation with the department and affected MPOs, shall coordinate emissions analyses where a non-exempt transportation project crosses the border of nonattainment or maintenance areas or MPO boundaries.

1. (1) NYSDOT shall make, in accordance with the provisions of this Part, air quality analyses in nonattainment or maintenance areas that do not include any MPO boundaries.
2. (2) NYSDOT shall make, in accordance with the provisions of this Part, air quality analyses in nonattainment or maintenance areas which are not entirely included in MPO boundaries. The results of any regional emissions analysis outside the MPO boundary shall be coupled with the MPO analysis for the remainder of the nonattainment or maintenance area, as appropriate, to allow a conformity determination based on the entire nonattainment or maintenance area.
3. (3) If more than one MPO is within the same nonattainment or maintenance area, NYSDOT shall coordinate the conformity determinations, in accordance with the provisions of this Subpart.

(i) Nonattainment or maintenance areas not entirely included in a single MPO boundary.

(j) Isolated rural nonattainment or maintenance areas. In isolated rural nonattainment and maintenance areas, NYSDOT shall coordinate, in accordance with the provisions of this section, the preparation of conformity determinations and air quality analysis. As required by 40 CFR 93.109(l) (see Table 1, section 200.9 of this Title), the conformity analysis to be used must be determined through consultation with all involved agencies.

1. (1) The affected MPOs and NYSDOT, as appropriate, shall work with the department to identify regionally significant projects that are not FHWA/FTA projects so that proper project information is included in the regional emissions analysis. The MPO shall solicit the necessary information from agencies that are recipients of Federal funding under title 23 U.S.C. or the Federal Transit Act for any regionally significant projects, regardless of the project funding source, in conjunction with MPO transportation plan and MPO TIP updates. In non-attainment and maintenance areas outside of MPO boundaries, NYSDOT shall solicit such information.

2. (2) If during the public participation process, or interagency consultation process, other regionally significant projects are identified, or there are changes in the design concept and scope of a regionally significant project that would affect the air quality analysis, the NYSDOT or affected MPO shall appropriately refine the conformity analysis in accordance with the provisions of this section.

   (l) Criteria and procedures: Localized CO, PM₁₀, and PM_2.5 violations (hot-spots).

3. (1) The FHWA/FTA or regionally significant project must not cause or contribute to any new localized CO, PM₁₀, and/or PM_2.5 violations, increase the frequency or severity of any existing CO, PM₁₀, and/or PM_2.5 violations, or delay timely attainment of any NAAQS or any required interim emission reductions or other milestones in CO, PM₁₀, and PM_2.5 nonattainment and maintenance areas. This criterion is satisfied without a hot-spot analysis in PM₁₀, and PM_2.5 nonattainment and maintenance areas for FHWA/FTA or regionally significant projects that are not identified in 40 CFR 93.123(b)(1) (see Table 1, section 200.9 of this Title). This criterion is satisfied for all other FHWA/FTA or regionally significant projects in CO, PM₁₀, and PM_2.5 nonattainment and maintenance areas if it is demonstrated that during the time frame of the transportation plan no new local violations will be created and the severity or number of existing violations will not be increased as a result of the project and the project has been included in a regional emissions analysis that meets applicable requirements in 40 CFR sections 93.118 and/or 93.119 (see Table 1, section 200.9 of this Title). The demonstration must be performed according to the consultation requirements in section 242-2.8 of this Part and the methodology requirements of 40 CFR 93.123 (see Table 1, section 200.9 of this Title).
4. (2) This paragraph applies for CO nonattainment areas as described in 40 CFR 93.109(f)(1) (see Table 1, section 200.9 of this Title). Each FHWA/FTA or regionally significant project must eliminate or reduce the severity and number of localized CO violations in the area substantially affected by the project. This criterion is satisfied with respect to existing localized CO violations if it is demonstrated that during the time frame of the transportation plan (or regional emissions analysis) existing localized CO violations will be eliminated or reduced in severity and number as a result of the project. The demonstration must be performed according to the consultation requirements of section 242-2.8 of this Part and the methodology requirements of 40 CFR 93.123 (see Table 1, section 200.9 of this Title).

(k) Consideration of regionally significant projects that are not FHWA/FTA projects.

(n) Research and data collection and transportation model development. The affected MPOs shall consult with NYSDOT, the department, and affected local air and transportation agencies before formally adopting initiatives related to research and data collection efforts in support of regional transportation model development.

1. (1) The affected MPOs shall provide a final copy of the MPO transportation plans, MPO TIPs and associated MPO transportation plan and MPO TIP conformity determinations with pertinent supporting materials to involved agencies.
2. (2) NYSDOT shall provide a final copy of program of transportation projects conformity determinations with pertinent supporting materials for nonattainment or maintenance areas outside MPO boundaries to the involved agencies.
3. (3) The department shall provide a final copy of all applicable SIP revisions and pertinent supporting materials to involved agencies.
4. (4) In the event that the final documents and supporting materials to be provided pursuant to this paragraph are excessively voluminous, the agency providing such documentation may provide a list of pertinent supporting documents necessary to analyze the final materials. Upon request the agency shall make the documents available.

(o) Provision of final documents.
