Lead and Copper Rule Revisions (LCRR)

The EPA published the Lead and Copper Rule Revisions (LCRR) in December 2021, which include significant changes to the current Lead and Copper Rule (LCR). The LCRR aims to protect communities from lead exposure in drinking water. The EPA has also announced its intention to further strengthen regulatory requirements through the Lead and Copper Rule Improvements (LCRI), which they plan to finalize in late 2024. The department began a stakeholder process for the LCRR in July 2022, hosting 26 stakeholder events through Summer 2023.

On August 14, 2023, the Water Quality Control Commission voted unanimously to take final action on the proposal to adopt the LCRR into Regulation 11. The new rule will become effective in September or October 2023 (as determined by the Secretary of State's office), with a compliance date of October 16, 2024.
