From a Local Area*
- Make full use of the collective knowledge and value of the interagency consultation committee. Routine meetings and frequent open communication is important to the success of a conformity determination.
- Have a clear and agreed-upon regionally significant project (RSP) definition.
- Communicate the RSP definition to all local governments and state agencies involved in road projects in the nonattainment area. It is very important to ensure that all appropriate officials are aware and understand the definition and how it may impact the conformity review.
- Develop a contingency plan to address future projects that may not have been identified during the long range transportation plan (LRTP) conformity review. The in-kind resources of the interagency consultation committee partners must be considered when a conformity review is necessary. Failure to do so may result in delays and added costs for the proposed transportation project.
- Successful transportation conformity planning ensures that Federal funding and approval goes to those transportation activities that are consistent with local and state air quality goals.
