The main purpose of this legislative text is to allow Congress to disapprove a specific rule set by the Environmental Protection Agency (EPA) regarding air pollution control in Indiana. This rule is part of a broader effort to manage emissions that cross state lines, which can impact air quality in multiple states. The key provision of this resolution states that Congress officially disapproves the EPA's rule on "Emissions Budget and Allowance Allocations for Indiana." By passing this resolution, the rule will not be enforced, meaning the regulations it established will have no legal effect.
