A joint resolution providing for congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the Environmental Protection Agency relating to "Air Plan Approval; Indiana; Regional Haze Plan for the Second Implementation Period".

SJRES 122 is a joint resolution seeking to disapprove an Environmental Protection Agency (EPA) rule that approved Indiana's Regional Haze Plan for the second implementation period under federal air quality regulations. If passed, the resolution would block the rule from taking effect, preventing the EPA's approval of Indiana's haze reduction plan from being enforced. This follows a standard congressional disapproval process under federal law that allows Congress to halt agency rules within a specific timeframe. The resolution directly affects the EPA's ability to implement the approved plan in Indiana.
