Five-Year Reviews

Purpose and Process

Five-Year Reviews are conducted in accordance with the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), which is more commonly known as Superfund. The U.S. Army conducts each review and prepares each Five-Year Review Report in cooperation with the EPA, Colorado Department of Public Health and Environment and Adams County Health Department.

The purpose of the review is to assess the ongoing protectiveness of the remedy for human health and the environment. A multiagency team also evaluates whether any changes to environmental standards that affect the site have occurred within the past five years. To learn more about the Five-Year Review process and what it involves, read this fact sheet.

Community Input Sought for 2025 Five-Year Review

The U.S. Army has started the 2025 Five-Year Review (FYR) process for the Rocky Mountain Arsenal (RMA) environmental cleanup and is seeking public input. Community members are encouraged to submit, in writing, any concerns or issues they would like to see addressed during the FYR. Once the FYR is complete, a draft document summarizing the findings will be made available for public review. All public comments received during this process will be reviewed and considered in the final report.
