Current through Register Vol. 35, No. 21, November 5, 2024

Section 20.2.99.137 - CRITERIA AND PROCEDURES - MOTOR VEHICLE EMISSIONS BUDGET

A. The transportation plan, TIP, and project not from a conforming transportation plan and TIP must be consistent with the motor vehicle emissions budget(s) in the applicable control strategy implementation plan (or implementation plan submission). This criterion applies as described in Subsections C through N of 20.2.99.128 NMAC. This criterion is satisfied if it is demonstrated that emissions of the pollutants or pollutant precursors described in Subsection C of 20.2.99.137 NMAC are less than or equal to the motor vehicle emissions budget(s) established in the applicable implementation plan or implementation plan submission.

B. Consistency with the motor vehicle emissions budget(s) must be demonstrated for each year for which the applicable (and/or submitted) implementation plan specifically establishes motor vehicle emissions budget(s), for the attainment year (if it is within the time frame of the transportation plan and conformity determination), for the last year of the timeframe of the conformity determination (as described under Subsection D of 20.2.99.125 NMAC), and for any intermediate years within the timeframe of the conformity determination as necessary so that the years for which consistency is demonstrated are no more than ten years apart, as follows.

(1) Until a maintenance plan is submitted:

(a) emissions in each year (such as milestone years and the attainment year) for which the control strategy implementation plan revision establishes motor vehicle emissions budget(s) must be less than or equal to that year's motor vehicle emissions budget(s); and

(b) emissions in years for which no motor vehicle emissions budget(s) are specifically established must be less than or equal to the motor vehicle emissions budget(s) established for the most recent prior year; for example, emissions in years after the attainment year for which the implementation plan does not establish a budget must be less than or equal to the motor vehicle emissions budget(s) for the attainment year.

(2) When a maintenance plan has been submitted:

(a) emissions must be less than or equal to the motor vehicle emissions budget(s) established for the last year of the maintenance plan, and for any other years for which the maintenance plan establishes motor vehicle emissions budgets; if the maintenance plan does not establish motor vehicle emissions budgets for any years other than the last year of the maintenance plan, the demonstration of consistency with the motor vehicle emissions budget(s) must be accompanied by a qualitative finding that there are no factors which would cause or contribute to a new violation or exacerbate an existing violation in the years before the last year of the maintenance plan; the interagency consultation process required by 20.2.99.116 NMAC through 20.2.99.124 NMAC shall determine what must be considered in order to make such a finding;

(b) for years after the last year of the maintenance plan, emissions must be less than or equal to the maintenance plan's motor vehicle emissions budget(s) for the last year of the maintenance plan;

(c) if an approved and/or submitted control strategy implementation plan has established motor vehicle emissions budgets for years in the timeframe of the transportation plan, emissions in these years must be less than or equal to the control strategy implementation plan's motor vehicle emissions budget(s) for these years: and

(d) for any analysis years before the last year of the maintenance plan, emissions must be less than or equal to the motor vehicle emissions budget(s) established for the most recent prior year.

C. Consistency with the motor vehicle emissions budget(s) must be demonstrated for each pollutant or pollutant precursor in Subsection B of 20.2.99.109 NMAC (or 20.2.99.101 NMAC) for which the area is in nonattainment or maintenance and for which the applicable implementation plan (or implementation plan submission) establishes a motor vehicle emissions budget.

D. Consistency with the motor vehicle emissions budget(s) must be demonstrated by including emissions from the entire transportation system, including all regionally significant projects contained in the transportation plan and all other regionally significant highway and transit projects expected in the nonattainment or maintenance area in the timeframe of the transportation plan.

(1) Consistency with the motor vehicle emissions budget(s) must be demonstrated with a regional emissions analysis that meets the requirements of 20.2.99.141 NMAC through 20.2.99.147 NMAC and 20.2.99.120 NMAC.

(2) The regional emissions analysis may be performed for any years in the timeframe of the conformity determination (as described under Subsection D of 20.2.99.125 NMAC) provided they are not more than ten years apart and provided the analysis is performed for the attainment year (if it is in the timeframe of the transportation plan and conformity determination) and the last year of the timeframe for the conformity determination. Emissions in years for which consistency with motor vehicle emissions budgets must be demonstrated, as required in Subsection B of 20.2.99.137 NMAC, may be determined by interpolating between the years for which the regional emissions analysis is performed.

(3) When the timeframe of the conformity determination is shortened under Paragraph (2) of Subsection D of 20.2.99.125 NMAC, the conformity determination must be accompanied by a regional emissions analysis (for informational purposed only) for the last year of the transportation plan, and for any year shown to exceed motor vehicle emissions budgets in a prior regional emissions analysis (if such a year extends beyond the timeframe of the conformity determination).

E. Motor vehicle emissions budgets in submitted control strategy implementation plan revisions and submitted maintenance plans.

(1) Consistency with the motor vehicle emissions budgets in submitted control strategy implementation plan revisions or maintenance plans must be demonstrated if US EPA has declared the motor vehicle emissions budget(s) adequate for transportation conformity purposes, and the adequacy finding is effective. However, motor vehicle emissions budgets in submitted implementation plans do not supersede the motor vehicle emissions budgets in approved implementation plans for the same Clean Air Act requirement and the period of years addressed by the previously approved implementation plan, unless US EPA specifies otherwise in its approval of a SIP.

(2) If US EPA has not declared an implementation plan submission's motor vehicle emissions budget(s) adequate for transportation conformity purposes, the budget(s) shall not be used to satisfy the requirements of this section. Consistency with the previously established motor vehicle emissions budget(s) must be demonstrated. If there are no previously approved implementation plans or implementation plan submissions with adequate motor vehicle emissions budgets, the interim emissions tests required by 20.2.99.138 NMAC must be satisfied.

(3) If US EPA declares an implementation plan submission's motor vehicle emissions budget(s) inadequate for transportation conformity purposes and conformity of a transportation plan or TIP has already been determined by US DOT using the budget(s), the conformity determination will remain valid. Projects included in that transportation plan or TIP could still satisfy 20.2.99.133 NMAC and 20.2.99.134 NMAC, which require a currently conforming transportation plan and TIP to be in place at the time of a project's conformity determination and that projects come from a conforming transportation plan and TIP.

(4) US EPA will not find a motor vehicle emissions budget in a submitted control strategy implementation plan revision or maintenance plan to be adequate for transportation conformity purposes unless the following minimum criteria are satisfied:

(a) the submitted control strategy implementation plan revision or maintenance plan was endorsed by the governor (or his or her designee) and was subject to a state public hearing;

(b) before the control strategy implementation plan or maintenance plan was submitted to US EPA, consultation among federal, state, and local agencies occurred; full implementation plan documentation was provided to US EPA; and US EPA's stated concerns, if any, were addressed;

(c) the motor vehicle emissions budget(s) is clearly identified and precisely quantified;

(d) the motor vehicle emissions budget(s), when considered together with all other emissions sources, is consistent with applicable requirements for reasonable further progress, attainment, or maintenance (whichever is relevant to the given implementation plan submission);

(e) the motor vehicle emissions budget(s) is consistent with and clearly related to the emissions inventory and the control measures in the submitted control strategy implementation plan revision or maintenance plan; and

(f) revisions to previously submitted control strategy implementation plans or maintenance plans explain and document any changes to previously submitted budgets and control measures; impacts on point and area source emissions; any changes to established safety margins (see Subsection AM of 20.2.99.7 NMAC for definition); and reasons for the changes (including the basis for any changes related to emission factors or estimates of vehicle miles traveled).

(5) Before determining the adequacy of a submitted motor vehicle emissions budget, US EPA will review the department's compilation of public comments and response to comments that are required to be submitted with any implementation plan. US EPA will document its consideration of such comments and responses in a letter to the department indicating the adequacy of the submitted motor vehicle emissions budget.

(6) When the motor vehicle emissions budget(s) used to satisfy the requirements of this section are established by an implementation plan submittal that has not yet been approved or disapproved by US EPA, the MPO and US DOT's conformity determinations will be deemed to be a statement that the MPO and US DOT are not aware of any information that would indicate that emissions consistent with the motor vehicle emissions budget will cause or contribute to any new violation of any standard; increase the frequency or severity of any existing violation of any standard; or delay timely attainment of any standard or any required interim emission reductions or other milestones.

F. Adequacy review process for implementation plan submissions. US EPA will use the procedure listing in Paragraph (1) of Subsection F of this section (20.2.99.137 NMAC) to review the adequacy of an implementation plan.

(1) When US EPA reviews the adequacy of an implementation plan submission prior to EPA's final action on the implementation plan:

(a) US EPA will notify the public through US EPA's website when US EPA receives an implementation plan submission that will be reviewed for adequacy;

(b) the public will have a minimum of 30 days to comment on the adequacy of the implementation plan submission; if the complete implementation plan is not accessible electronically through the internet and a copy is requested within fifteen (15) days of the date of the website notice, the comment period will be extended 30 days from the date that a copy of the implementation plan is mailed;

(c) after the public comment period closes, US EPA will inform the department in writing whether US EPA has found the submission adequate or inadequate for use in transportation conformity, including response to any comments submitted directly and review of comments submitted through the department process, or US EPA will include the determination of adequacy or inadequacy in a proposed or final action approving or disapproving the implementation plan under Subparagraph (c) of Paragraph (2) of Subsection F of this section (20.2.99.137 NMAC);

(d) US EPA will publish a federal register notice to inform the public of US EPA's finding; if EPA finds the submission adequate, the effective date of this finding will be fifteen (15) days from the date the notice is published as established in the federal register notice, unless US EPA is taking a final approval action on the SIP as described in Subparagraph (c) of Paragraph (2) for Subsection F for this section (20.2.99.137 NMAC);

(e) US EPA will announce whether the implementation plan submission is adequate or inadequate for use in transportation conformity on US EPA's website; the website will also include US EPA's response to comments of any comments were received during the public comments period;

(f) if after US EPA has found a submission adequate, US EPA has cause to reconsider this finding, US EPA will repeat actions described in Subparagraphs (a) through (e) of Paragraph (1) of Subsection F or Paragraph (2) of Subsection F of 20.2.99.137 NMAC unless US EPA determines that there is no need for additional public comment given the deficiencies of the implementation plan submission; in all cases where US EPA reverses its previous finding to a finding of inadequacy under Paragraph (1) of Subsection F of 20.2.99.137 NMAC, such a finding will become effective immediately upon the date of US EPA's letter to the department;

(g) if after EPA has found a submission inadequate, US EPA has cause to reconsider the adequacy of that budget, US EPA will repeat actions described in Subparagraphs (a) through (e) of Paragraph (1) of this section (20.2.99.137 NMAC).

(2) When US EPA reviews the adequacy of an implementation plan submission simultaneously with US EPA's approval or disapproval of the implementation plan:

(a) US EPA's federal register notice of proposed or direct final rulemaking will serve to notify the public that US EPA will be reviewing the implementation plan submission for adequacy;

(b) the publication of the notice of proposed rulemaking will start a public comment period of at least thirty (30) days;

(c) US EPA will indicate whether the implementation plan submission is adequate and thus can be used for conformity either in US EPA's final rulemaking or through the process described in Subparagraphs (c) through (e) of Paragraph (1) of Subsection F of this section (20.2.99.137 NMAC); if US EPA makes an adequacy finding through a final rulemaking that approves the implementation plan submission, such a finding will become effective upon the publication date of US EPA's approval in the federal register, or upon the effective date of US EPA's approval if such action is conducted through direct final rulemaking; US EPA will respond to comments received directly and review comments submitted through the department process and include the response to comments in the applicable docket.
