Final Error Corrections Rule

EPA is finalizing a rule to correct minor errors that have accumulated over time in four NSR regulations. While these minor errors, including outdated cross references and typographical errors, have not materially impeded the effective operation of the NSR program, EPA believes that it is important to remove such errors from the regulations in order to provide regulatory certainty and clarity.  The corrections are all considered to be non-substantive and are intended to provide clarity and precision to the NSR regulations without altering any NSR policy or changing the NSR program as a whole. EPA is also removing from the NSR regulations various provisions, such as certain “grandfathering” provisions, that, with the passage of time, no longer serve any practical function or purpose.

    On June 22, 2021, the U.S. Environmental Protection Agency (EPA) finalized a rule to correct non-substantive errors, and make conforming changes to address the 1990 Clean Air Act (CAA) Amendments (e.g., revisions to sections 112 and 169) in the New Source Review (NSR) rules. The NSR regulations in 40 CFR 51 and 52 have undergone restructuring and revisions over the years and a number of inadvertent errors have accumulated during that time.
