S.J.Res. 122 is a congressional resolution seeking to overturn an Environmental Protection Agency rule approving Indiana's regional haze plan for the period through 2028. The rule, published in January 2026, establishes air quality standards intended to reduce haze in national parks and wilderness areas across the region. If passed by both chambers of Congress, this resolution would eliminate the EPA's approval and prevent the rule from taking effect, essentially rejecting Indiana's plan for controlling air pollution that contributes to regional haze. The resolution was introduced by Senator Whitehouse and represents an exercise of Congress's authority to disapprove federal agency regulations. No specific funding or implementation timeline beyond the rule's existing effective date is addressed in the resolution.
