§ 1220 Criteria and procedures: Motor vehicle emissions budget (TIP).

(a) The TIP must be consistent with the motor vehicle emissions budget(s) in the applicable implementation plan (or implementation plan submission). This criterion applies during the transitional period and the control strategy and maintenance periods, except as provided in § 1237. This criterion may be satisfied if the requirements in paragraphs (b) and (c) of this section are met.

(b) For areas with a conforming transportation plan that fully meets the content requirements of § 1207(a), this criterion may be satisfied without additional regional emissions analysis if:

(1) Each program year of the TIP is consistent with the Federal funding which may be reasonably expected for that year, and required State/local matching funds and funds for State/local funding-only projects are consistent with the revenue sources expected over the same period; and

(2) The TIP is consistent with the conforming transportation plan such that the regional emissions analysis already performed for the plan applies to the TIP also. This requires a demonstration that:

(i) The TIP contains all projects which must be started in the TIP's timeframe in order to achieve the highway and transit system envisioned by the transportation plan in each of its horizon years;

(ii) All TIP projects which are regionally significant are part of the specific highway or transit system envisioned in the transportation plan's horizon years; and

(iii) The design concept and scope of each regionally significant project in the TIP is not significantly different from that described in the transportation plan.

(3) If the requirements in paragraphs (b)(1) and (b)(2) of this section are not met, then:

(i) The TIP may be modified to meet those requirements; or

(ii) The transportation plan must be revised so that the requirements in paragraphs (b)(1) and (b)(2) of this section are met. Once the revised plan has been found to conform, this criterion is met for the TIP with no additional analysis except a demonstration that the TIP meets the requirements of paragraphs (b)(1) and (b)(2) of this section.

(c) For areas with a transportation plan that does not meet the content requirements of § 1207(a), a regional emissions analysis must meet all of the following requirements:

(1) The regional emissions analysis shall estimate emissions from the entire transportation system, including all projects contained in the proposed TIP, 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;

(2) The analysis methodology shall meet the requirements of § 1231(c); and

(3) The regional emissions analysis shall satisfy the requirements of § 1219(b)(1), § 1219(b)(5), and § 1219(c).
