Industry Organization Challenges EPA Cross State Air Pollution Rule

As the saying goes, "no good neighbor rule goes unpunished." Thus, the latest attempt by the U.S. Environmental Protection Agency ("EPA") to promulgate a Revised Cross-State Air Pollution Rule ("CSAPR") Update under the "good neighbor provision" of the Clean Air Act and in response to the D.C. Circuit's remand of the previous version of the CSAPR Update has been challenged in court. On June 25, 2021, Midwest Ozone Group—an affiliation of companies, trade organizations, and associations created to advance its members interests regarding national ambient air quality programs—filed a  petition for review of the final rule of EPA published in the Federal Register at 86 Fed. Reg. 23,054 (April 30, 2021) entitled the "Revised Cross-State Air Pollution Rule Update for the 2008 Ozone NAAQS." The petition does not provide any details at this point regarding the basis for the group's challenge to the Revised CSAPR Update.
