On August 5, 2025, Region III issued a Unilateral Administrative Order (UAO) to community water systems in Virginia that failed to comply with the requirements of the Safe Drinking Water Act's ( SDWA ) Lead and Copper Rule Revisions (LCRR). Pursuant to 40 C.F.R. 141.84, community water systems ( CWS ) and non- transient non- community water systems ( NTNCWS ) were required to submit an initial service line inventory to the State by October 16, 2024. EPA issued the UAOs to these facilities because they had not complied with these requirements. EPA directly implements LCRR, but EPA has notified Virginia of the action against these facilities.
