The Environmental Protection Agency (EPA or Agency) is issuing a short delay of the March 16, 2021, effective date of the National Primary Drinking Water Regulations: Lead and Copper Rule Revisions (LCRR), published in the Federal Register on January 15, 2021. The LCRR will now become effective on June 17, 2021. This final rule does not change the compliance date of January 16, 2024. This delay in the effective date is consistent with Presidential directives issued on January 20, 2021, to heads of Federal agencies to review certain regulations, including the LCRR. The sole purpose of this delay is to enable EPA to take public comment on a longer extension of the effective date for EPA to undertake its review of the rule in a deliberate and thorough manner consistent with the public health purposes of the Safe Drinking Water Act and the terms and objectives of recent Presidential directives and in consultation with affected stakeholders.
