## Abstract

The Environmental Protection Agency (EPA) is taking final action to approve revisions to the State Implementation Plan (SIP), and Operating Permits Program for the State of Nebraska as submitted on August 22, 2018. This action adopts the 2015 primary and secondary National Ambient Air Quality Standards for Ozone, published in the Federal Register on October 26, 2015. The EPA is also taking final action to approve revisions which are administrative in nature. These revisions include updating a reference to EPA's regulation used in the definition of "Global Warming Potentials", removing "Greenhouse Gases" from the definition of "Regulated Air Pollutant", and updating a reference to EPA's regulations used in the definition of "Volatile Organic Compound". Other typographical and reformatting revisions are also being made. Approval of these revisions will not impact air quality, ensures consistency between the State and Federally-approved rules, and ensures Federal enforceability of the State's rules.
