Providing for congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the Environmental Protection Agency relating to "National Primary Drinking Water Regulations for Lead and Copper: Improvements (LCRI)".

HJRES 18 is a resolution to block an Environmental Protection Agency (EPA) rule that would have updated national drinking water standards for lead and copper. The EPA rule, published in October 2024, proposed stricter limits on lead and copper in public water systems to improve safety. If passed, this resolution would prevent the rule from taking effect, maintaining current standards instead of implementing the proposed changes. The resolution does not create new rules but stops the EPA's proposed regulation from being enforced.
