The U.S. Environmental Protection Agency (EPA) is responsible for receiving and reviewing environmental impact statements (EISs) prepared by the Federal agencies. EPA's NEPA website provides resources on the NEPA process, EPA's role, EIS filing guidance, geographic contacts and information, and environmental justice.
EPA publishes a weekly notice of availability in the Federal Register that lists each draft or final EIS received ("filed") during the previous week. Publication of this notice starts the official counting of a required time period, generally a minimum 45-day public comment period for a draft EIS and 30-day "wait period" before making a decision after issuing a final EIS. (See EISs with open comment periods.)
