Reevaluations of NEPA documents
[ NCHRP 25-25 (Research for the AASHTO Standing Committee on the Environment) ]

  Project Data
Funds: $55,000
Research Agency: ICF Consulting, Inc.
Principal Investigator: John Hansel
Effective Date: 2/22/2007
Completion Date: 4/1/2008

At times, delays project development process force the project to wait years before proceeding to construction. All the while, the environmental studies that were conducted early have a shelf life and may need a refreshing prior to the project moving forward. Not only do the NEPA documents have a shelf life, but so do the specific environmental studies to go into it. Every state conducts reevaluations of their NEPA documents and specific studies, but recently several states have had problems with the detail necessary, the processing of these reevaluations and knowing exactly what studies need refreshed, to what degree and how often. This task developed a guide for NEPA professionals on when reevaluations are needed, to what degree of detail and how often they require to be produced.
