EPA to Brief NDWAC on Proposed LCRI

Good morning to all,

In the January 11, 2024 Federal Register (NDWAC Meeting_LCRI_2024-01-31) EPA announced that the National Drinking Water Advisory Council (NDWAC) will meet on January 31, 2024, from 10:30 am to 5:30 pm (ET).

As stated in the enclosed Federal Register: “The primary purpose of the meeting is for EPA to consult with the NDWAC as required by the SDWA on a final National Primary Drinking Water Regulation: Lead and Copper Rule Improvements.”

This will be a virtual meeting of the NDWAC. According to the Federal Register notice, information on how to register, and the meeting agenda will be posted at the following location: https://www.epa.gov/ndwac

In the December 6, 2023, Federal Register, EPA published the proposed Lead and Copper Rule Improvements (LCRI) for a 60-day public comment period. Public comments are due by February 5, 2024. EPA will hold a virtual public hearing on January 16, 2024.

Here are a few highlights from the proposed LCRI:

• Eliminates the 10 ppb trigger value in the Lead and Copper Rule Revisions (LCRR), and instead proposes to lower the lead Action Level from 15 ppb to 10 ppb.
• If a public water system has lead service lines (LSLs), or galvanized requiring replacement service lines, they must all be replaced within 10 years, with some exceptions.
• For tap samples collected from a home served by an LSL, the utility must collect five one-liter samples, and test for lead in the first and fifth liter (and the highest result will be used in determining the 90th percentile lead value).
