Melanie Bolden and Holly Young, EPA Office of Water

Developing a lead service line (LSL) inventory and identifying the location of LSLs is the first step for beginning LSL replacement and protecting public health. The purpose of this presentation is to walk through the EPA’s Guidance for Developing and Maintaining a Lead Service Line Inventory. The guidance provides support for the service line inventory requirements according to the 2021 Lead & Copper Rule Revisions, referred to as LCRR.

2: Colorado Lead Service Line Inventory Guidance

Melanie Criswell and Haley Orahood, Colorado Department of Public Health and Environment

This presentation will cover Colorado’s initial service line inventory guidance policy, which builds on EPA’s LSL inventories guidance document. Colorado water systems requested a policy to formalize requirements and expectations related to issues such as calling galvanized lines non-lead, statistical modeling, and non-lead cutoff dates. Colorado will discuss some of state specific policy decisions on the initial service line inventory and potential Lead and Copper Rule Improvements impacts.
