Section 20.11.3.111 - CRITERIA AND PROCEDURES: LATEST EMISSIONS MODEL

A. The conformity determination shall be based on the latest emission estimation model available. This criterion is satisfied if the most current version of the motor vehicle emissions model specified by EPA for use in the preparation or revision of implementation plans for Bernalillo county is used for the conformity analysis. When options are allowed by EPA, the TCTC, as part of the interagency consultation described in Paragraph (1) of Subsection D of 20.11.3.105 NMAC, shall be responsible for determining the most appropriate emission estimation model to be used.

B. EPA shall consult with DOT to establish a grace period following the specification of any new model.

(1) The grace period shall be no less than three months and no more than 24 months after notice of availability is published in the federal register.

(2) The length of the grace period shall depend on the degree of change in the model and the scope of re-planning likely to be necessary by MPOs in order to assure conformity. If the grace period shall be longer than three months, EPA shall announce the appropriate grace period in the federal register.

C. Transportation plan and TIP conformity analyses for which the emissions analysis was begun during the grace period or before the federal register notice of availability of the latest emission model may continue to use the previous version of the model. Conformity determinations for projects may also be based on the previous model if the analyses were begun during the grace period or before the federal register notice of availability, and if the final environmental document for the project is issued no more than three years after the issuance of the draft environmental document.
