Chapter 1: Understanding the Regulatory Landscape
Overview of LCRI and Key Deadlines
The Lead and Copper Rule Improvements (LCRI) require that every community water system (CWS) and every non-transient non-community water system (NTNCWS) in the U.S. inventory and fully replace all lead, galvanized requiring replacement (GRR), and unknown service lines on both public and private property. Transient non-community systems are excluded from the LCRI.
Key compliance milestones:
- Service Line Replacement Plan and Inventory: Due by November 1, 2027
- Full Line Replacement Deadline: Within 10 years (by 2037), unless a documented, state-approved deferment applies
- Average Annual Replacement Rate: Cumulative 10% average annual rate, assessed after program year 3 (i.e., by 2029), not specifically starting in calendar year 2028
- Partial replacements are generally prohibited (emergency exceptions apply)

Why it matters:
Substantial penalties apply for non-compliance. Funding, eligibility, and bid opportunities are tied to these regulatory timelines.
