Lead and Copper Rule Revisions and Lead and Copper Improvements

Lead and Copper Rule Revisions (LCRR) and Lead and Copper Rule Improvements (LCRI)

The federal Lead and Copper Rule (LCR), Lead and Copper Rule Revisions (LCRR) and the Lead and Copper Rule Improvements (LCRI) apply to all community (C) and non-transient non-community (NTNC) public water systems. The U.S. Environmental Protection Agency (EPA) issued the final LCRR in 2021 requiring public water suppliers to evaluate their service lines and submit initial service line inventories by October 16, 2024, which included making the inventory accessible to customers. The intent of the service line inventory is to schedule removal and replacement of service lines identified as having lead.

The EPA issued the final LCRI in October 2024 requiring identification and replacement of lead pipes within 10 years (by 2034) at C and NTNC water systems. Lead connectors (also called pigtails or goosenecks) were added to the service line inventory requirements, along with continued efforts to resolve unknown service lines from the initial inventory. Public water suppliers must add information to their annual consumer confidence reports describing the service line inventory. All elements of the LCRI will take effect on November 1, 2027.

Drinking Water Services intends to adopt the LCRI and receive primacy for the federal LCRI before November 1, 2027.
