The U.S. Environmental Protection Agency (EPA) today announced its Lead and Copper Rule revisions . Once the final rule is published in the Federal Register , the rulemaking is officially complete. AWWA is analyzing the materials released today by EPA, but on first review, the final rule reflects many of the core elements of the November 2019 proposal including: A requirement that utilities develop lead service line (LSL) inventories regardless of service line ownership, a necessary first step to eventually create a LSL removal program. Utilities must always pursue full lead service line replacement when disturbing a lead service line and are required to replace the utility-owned portion of a lead service when a customer elects to replace the customer-owned portion of the line. Utilities will be required to test elementary schools and childcare facilities. The 15 µg/L lead action level (90th percentile lead level) remains unchanged, but there is a requirement for public notification within 24 hours when a system exceeds the lead action level. Corrosion control treatment requirements include a new “trigger level” (a 90th percentile lead level of 10 µg/L), that when exceeded a system that currently employs corrosion control would be required to re-optimize existing treatment. Systems that do not currently treat for corrosion control would be required to conduct a corrosion control study. Important differences in the final rule from the proposal include: Requirement that LCR compliance monitoring samples at a home with a lead service line be a fifth liter sample rather than a first liter sample. Revision of the proposed “find and fix” requirements triggered based on individual lead values above 15 µg/L. Clarification of how galvanized iron pipe should be treated in developing inventories and sample plans. AWWA President Melissa Elliott issued a public statement regarding the revisions. As AWWA evaluates the final rule, systems are advised to: Begin now to take steps to meet compliance deadlines. In order to meet rule requirements that take effect in 3 – 4 years (e.g., compliance sample pool and protocol, lead service line replacement and lead education) water systems need to organize available information and develop a plan to assure compliance when the rule provisions take effect. Talk about lead with your customers. Every water system has a story to tell. Customers want to know about the likely sources of lead present in your community, what the system is doing to control corrosivity, and options for customers concerned about lead to take additional actions. Suggestions on how to communicate effectively are available in AWWA’s Lead Communications Toolkit . Review and refine current corrosion control practice. All systems serving more than 50,000 persons have a formal corrosion control treatment program. All other systems are managing their supplies, perhaps with active treatment measures, to reliably comply with the current LCR action levels. Understanding and modifying corrosion control take careful study and evaluation. Develop a lead service line inventory and strategy to remove lead service lines. Lead service lines are a large potential source of lead in drinking water. The Lead Service Line Replacement Collaborative provides an introduction to building a community-based approach to lead service replacement. Replacing lead service lines completely will require a shared effort with customers, local government leaders, and numerous other local agencies. AWWA has resources available to help utilities communicate about lead in drinking water, including: AWWA Lead Resource page , which includes a printable brochure on lead Lead whiteboard animation available on YouTube Lead Communications Toolkit DrinkTap’s Lead in Water page Questions about EPA’s latest LCR action can be directed to Steve Via , director of federal relations, or Greg Kail , director of communications.
