## Abstract

The U.S. Environmental Protection Agency (EPA) is making minor, non-substantive changes to a final rule, "Revisions to the Unregulated Contaminant Monitoring Rule (UCMR 5) for Public Water Systems and Announcement of Public Meetings," that appeared in the Federal Register on December 27, 2021. These corrections do not change any final action taken by EPA on December 27, 2021; rather, they simply clarify the amendatory instructions.
