This joint resolution aims to exercise congressional authority under chapter 8 of title 5, United States Code, to disapprove a specific rule issued by the Environmental Protection Agency (EPA). The rule in question is titled "Air Plan Approval; Indiana; Regional Haze Plan for the Second Implementation Period" and was published in the Federal Register on January 26, 2026. Should this resolution be enacted by Congress, it would formally reject the EPA's approval of Indiana's regional haze plan. As a direct consequence, the disapproved rule would be rendered without any force or effect , preventing its implementation and impact on air quality regulations in Indiana.
