Yesterday, EDF submitted comments to the Environmental Protection Agency (EPA) on their proposed revisions to the Lead and Copper Rule (LCR), focusing on changes that EPA should to make to the:
- Definition of a lead service line (LSL);
- Requirements for water systems to develop LSL inventories; and
- Notification of individual consumers who drink water that passes through an LSL.
We highlighted strengths and weaknesses of the LCR in a blog earlier this week, and we encourage states and communities to consider adopting the positive provisions now in addition to the changes we ask EPA to adopt in these comments. Below is a summary of our comments on these three issues. We plan to address other issues on the proposed revisions to the LCR in later comments.
Lead Service Line Definition
EPA’s proposed change to the current definition of an LSL at 40 CFR § 141.2 is flawed because it continues to exempt goosenecks, pigtails, or other connectors made of lead. These connectors are a major source of lead in drinking water not just because they are made of lead, but because they can release significant amounts of lead particulate into water as they flex with temperature, are scoured by turbulent water flow, and as other conditions change.
The exemption of these connectors from the definition of an LSL would render a water system’s LSL inventory and periodic notices to customers misleading because service lines described as “non-lead” may actually have some lead pipe in them. This will give residents a false sense of security. We recommend that the agency modify the proposed definition by deleting the exemption and explicitly stating that goosenecks, pigtails and connectors made of lead are LSLs.
