 line renewal projects, adjacent projects by municipalities or other utilities, LCRI compliance monitoring results, and cooperation with its customers with respect to replacing the customer-owned portion of the LSL as necessary. In certain cases, these and other factors may result in a shorter or longer time frame for replacement. Because replacing the external LSL in its entirety is advised by several water industry organizations including the U.S. National Drinking Water Advisory Council, the Lead Service Line Replacement Collaborative, and the American Water Works Association, the Company’s preferred approach is to replace the entire external LSL if lead is found on either the Company or customer portion of the service line; full LSL replacement is also consistent with the LCRR and final LCRI. The Lead Service Line Replacement Collaborative is a diverse group of public health, water utility, environmental, labor, consumer and housing organizations from across the country working together to encourage communities to accelerate the full replacement of LSLs through collaborative efforts at the local level.

As part of its ongoing water main replacement and service line renewal projects, and in accordance with applicable state regulations and anticipation of updated federal regulation, the Company has been replacing LSLs for many years in accordance with current scientific guidance. Also, the Company utilizes appropriate corrosion control techniques as necessary to comply with current water quality regulatory requirements.

National Primary Drinking Water Regulations

On April 10, 2024, the EPA announced a final National Primary Drinking Water Regulation (“NPDWR”) for six PFAS, including perfluorooctanoic acid (“PFOA”), perfluorooctane sulfonic acid (“PFOS”), perfluorononanoic acid (“PFNA”), hexafluoropropylene oxide dimer acid (“HFPO-DA”, commonly known as “GenX Chemicals”), perfluorohexane sulfonic acid (“PFHxS”), and perfluorobutane sulfonic acid (“PFBS”). The NPDWR for PFAS establishes legally enforceable levels, called Maximum Contaminant Levels (“MCLs”), for PFAS in drinking water. Utilities will be required to complete their initial monitoring for PFAS by 2027, followed by ongoing compliance monitoring. Utilities will be required to comply with the new MCLs by April 2029, implementing solutions to reduce PFAS levels where needed. Beginning in April 2029, utilities that exceed any of the PFAS MCLs will be required to provide notification to the public of the violation.
