Providing for congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the Environmental Protection Agency relating to "Reconsideration of the National Ambient Air Quality Standards for Particulate Matter".

H.J. Res. 117 is a joint resolution that would disapprove an Environmental Protection Agency (EPA) rule concerning the reconsideration of National Ambient Air Quality Standards for particulate matter. The EPA rule, published on March 6, 2024, was part of the agency’s process to review these standards, which set limits for harmful air pollutants. This resolution invokes a congressional disapproval procedure under federal law to block the rule from taking effect. If enacted, the rule would have no force or effect, preserving the existing air quality standards for particulate matter.
