## Abstract

The Environmental Protection Agency (EPA) is approving Wisconsin's additions and amendments to chapters NR 400, NR 428, and NR 484 of the Wisconsin Administrative Code (Wis. Adm. Code). These changes clarify existing requirements and ensure clear and consistent implementation of Wisconsin's control requirements for emissions of nitrogen oxide (NO<INF>X</INF>). EPA proposed to approve this action on July 17, 2024, and received no comments.
