The degree of specificity required in the transportation plan and the specific travel network assumed for air quality modeling do not preclude the consideration of alternatives in the NEPA process or other project development studies. Should the NEPA process result in a project with design concept and scope significantly different from that in the transportation plan or TIP, the project shall meet the criteria in 20.11.3.109 NMAC through 20.11.3.119 NMAC for projects not from a TIP before NEPA process completion.
