[Code of Federal Regulations] [Title 40, Volume 17] [Revised as of July 1, 2002] From the U.S. Government Printing Office via GPO Access [CITE: 40CFR93.107] [Page 553] TITLE 40--PROTECTION OF ENVIRONMENT CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED) PART 93--DETERMINING CONFORMITY OF FEDERAL ACTIONS TO STATE OR FEDERAL IMPLEMENTATION PLANS--Table of Contents Subpart A--Conformity to State or Federal Implementation Plans of Transportation Plans, Programs, and Projects Developed, Funded or Approved Under Title 23 U.S.C. or the Federal Transit Laws Sec. 93.107 Relationship of transportation plan and TIP conformity with the NEPA process. 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 must meet the criteria in Secs. 93.109 through 93.119 for projects not from a TIP before NEPA process completion.
