This joint resolution proposes to nullify a specific rule promulgated by the Environmental Protection Agency (EPA) through the mechanism of the Congressional Review Act. The resolution explicitly states Congress's disapproval of the EPA's action, which would prevent the rule from taking effect. The EPA rule targeted by this resolution is titled "Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category--Deadline Extensions." By passing this resolution, Congress intends to revoke any deadline extensions that the EPA had established for environmental compliance within the steam electric power generating sector, ensuring the original compliance timelines remain in force.
