EPA Launches Online Tool for EIS Access


The Environmental Protection Agency (EPA) launched an interactive web-based mapping tool that provides the public with access and information on Environmental Impact Statements (EIS) filed with EPA for major projects proposed on federal lands and other proposed federal actions.

When visiting the website, users can click on any state for a list of EISs, including information about the potential environmental, social and economic impacts of these projects.

The National Environmental Policy Act (NEPA) requires federal agencies to consider the impacts of proposed actions, as well as any reasonable alternatives as part of their decision-making process. For proposed projects with potentially significant impacts, federal agencies prepare a detailed EIS that is filed with EPA and made available for public review and comment.

EPA is required to review and comment on Environmental Impact Statements prepared by other federal agencies.

“This interactive tool makes it easier for the public to be informed about the environment around them,” said Cynthia Giles, assistant administrator for EPA’s Office of Enforcement and Compliance Assurance, which oversees NEPA compliance. “Major projects and decisions have the potential to affect the environment where you work and live. I encourage everyone to check out the tool, stay informed and lend your voice.”

The user can click on a state in the map and is provided with comment letters submitted by the EPA on EISs within the last 60 days. The tool also provides users with the information they need to identify projects with open comment periods, including how to submit comments.
