On August 4, 2022, EPA released Guidance for Developing and Maintaining a Service Line Inventory to support water systems with their efforts to develop inventories and to provide states with needed information for oversight and reporting to EPA. The guidance provides essential information to help water systems comply with the Lead and Copper Rule Revisions requirement to prepare and maintain an inventory of service line materials by October 16, 2024. Specifically, EPA’s Lead Service Line Inventory guidance:

• Provides best practices for inventory development and communicating information to the public.
• Includes a template for water systems, states, and Tribes to use or adapt to create their own inventory.
• Contains case studies on developing, reviewing, and communicating about inventories.
• Highlights the importance of prioritizing inventory development in disadvantaged communities and where children live and play.

EPA is harmonizing regulatory requirements with unprecedented funding through President Biden’s Bipartisan Infrastructure Law to make rapid progress on removing harmful lead from America’s drinking water.

**Note from Iowa DNR:  We are currently reviewing the 160 page guidance document  and performing a crosswalk of our draft lead service line inventory template with the example template that EPA has released.  We will need time to ensure that we understand the guidance and make any modifications necessary to our template based upon pilot testing and the EPA guidance.  We encourage you to review the guidance and register for the webinar, but as an agency we have not finalized our template or made decisions on items that EPA has left to the state's discretion.
