Lead Service Line Inventory
On December 16, 2021, after a public comment period, the US Environmental Protection Agency (EPA) announced new revisions to the Lead and Copper Rule (LCR), the first significant changes in over 30 years. The EPA's new rule, referred to as the Lead and Copper Rule Improvements (LCRI), aims to strengthen the LCR to better protect children and communities from the risk of lead exposure.
The EPA identified priority improvements from the LCRI:
- Proactive and equitable lead service line replacement (LSLR);
- Strengthening compliance to tap sampling to better identify communities most at risk of lead in drinking water and to compel reduction actions; and
- Reducing the complexity of the regulation through improvement of the action and trigger level construct.
All community and non-transient non-community (NTNC) water systems were required to develop an initial inventory of service lines that meets LCRR requirements, including service line materials classification and information sources, for both the public and private portions of every service line, and submit their lead service line inventories to the state.
Service Line Material Identification – Project Update (2026)
Throughout 2024 and 2025, the PUD conducted service line inventories for each of the five largest community water systems within the District (Riverview, Sandy Shores, Sunvale, Riverbend, and Metaline Falls). The PUD contacted customers through phone calls, emails, letters, and in‑person conversations with Water System Operators to assist with pipe material identification. Thank you to everyone who participated, your support has been greatly appreciated.
As required, the PUD submitted its initial inventory reports to the state by October 16, 2024, and has continued refining the inventory since then.
In summary:
- The majority of service lines inventoried have been classified as lead‑free, with the remaining lines classified as unknown material.
- The PUD has not identified any service lines containing lead. We will continue reaching out to customers as needed to complete identification for the remaining unknown lines.
- Annual reporting is required by the EPA and the Washington State Department of Health Office of Drinking Water.
- Customers with an unknown material service line will receive a required notification letter and/or email from the PUD as part of ongoing compliance and verification efforts.
