Environmental Impact Statement (EIS) Database

The Environmental Impact Statement (EIS) Database provides information about EISs prepared by federal agencies, as well as EPA's comments concerning the EISs.

All EISs are filed with EPA, and EPA publishes a "Notice of Availability" each week in the Federal Register. The "Notice of Availability" is the start of the 45-day public comment period for Draft EISs. This notice is also the start of the 30-day "wait period" for Final EISs, in which agencies are generally required to wait 30 days before making a decision on a proposed action.

This database contains:

  • Records of all EISs received by EPA since 1987
  • EPA comment letters on EISs since 2001
  • Electronic (PDF) versions of EISs received by EPA since October 2012

For questions regarding the project, the EIS, or the list of cooperating agencies (where applicable), please contact the lead agency directly.
