EPA Lead and Copper Rule Comments Due April 12 by ACWA Staff Apr 7, 2021 Water News A 30-day public comment period on the U.S. Environmental Protection Agency’s revised Lead and Copper Rule (LCR) ends April 12. ACWA members wanting to submit comments can do so online. The EPA announced March 10 that it is extending the effective date for the revised LCR to allow time for more public input. To achieve this goal, EPA issued two notices regarding the LCR. The first notice extends the LCR effective date from March 16, 2021 to June 17, 2021. The second notice proposes to extend the effective date an additional six months to Dec. 16, and extend the compliance deadline from January 16, 2024 to September 16, 2024. This longer extension is designed to give EPA more time to review the rule consistent with recent Biden Administration directives and to further consult with affected stakeholders to determine how, or if, the LCR will be changed. ACWA is tracking this issue closely and plans to weigh in during the public comment period. The recently revised LCR maintains the federal action level for lead in drinking water at 15 parts per billion (ppb), the point at which water systems must begin replacing lead service lines. It adds a trigger level of 10 ppb that requires water systems to reassess their water treatment processes and potentially add corrosion-control measures. The rule also requires water utilities to notify customers within 24 hours of system-wide lead concentrations exceeding action levels, requires utilities to replace 3% of lead service lines (previously 7%) in communities where high lead levels are discovered, and mandates testing in elementary schools and child care facilities for the first time at the national level. For questions regarding the LCR, please contact Federal Relations Representative Madeline Voitier.
