Proposal to Strengthen Lead and Copper Rule

On November 30, 2023, U.S. EPA announced the proposed Lead and Copper Rule Improvements (LCRI). The proposed LCRI is a major advancement in protection from the significant, and irreversible, health effects that can occur after being exposed to lead in drinking water.
  
Key provisions in the proposal include:

• Achieving 100% Lead Pipe Replacement within 10 years. The proposed LCRI would require the vast majority of water systems to replace lead services lines within 10 years.
• Locating Legacy Lead Pipes. Under the proposed LCRI, all water systems would be required to regularly update their inventories, create a publicly available service line replacement plan, and identify the materials of all service lines of unknown material.
• Improving Tap Sampling. The proposed LCRI would require water systems to collect first liter and fifth liter samples at sites with lead service lines and use the higher of the two values when determining compliance with the rule.
• Lowering the Lead Action Level. EPA is proposing to lower the lead action level from 15 µg/L to 10 µg/L. When a water system’s lead sampling exceeds the action level, the system would be required to inform the public and take action to reduce lead exposure while concurrently working to replace all lead pipes.
• Strengthening Protections to Reduce Exposure. Water systems with multiple lead action level exceedances would be required to conduct additional outreach to consumers and make filters certified to reduce lead available to all consumers.

Taken together, these provisions in the proposed LCRI would strengthen public health protections, reduce complexity, and streamline implementation. EPA anticipates finalizing the LCRI prior to October 16, 2024.
