The U.S. Library of Congress announced Senate Joint Resolution 188 (S.J.Res.188), a measure introduced to disapprove a rule from the Environmental Protection Agency (EPA). This resolution specifically targets the EPA's "Final Repeal" of "National Emission Standards for Hazardous Air Pollutants: Coal- and Oil-Fired Electric Utility Steam Generating Units.

The joint resolution, filed under chapter 8 of title 5, United States Code, seeks to block the EPA's action. If passed, S.J.Res.188 would prevent the repeal of these emission standards, thereby maintaining regulations on hazardous air pollutants from coal- and oil-fired power plants.
