NTAA’s PRK for EPA’s Revisions to Prevention of Significant Deterioration (PSD) and Nonattainment New Source Review (NNSR): Regulations Related to Project Emissions Accounting
The U.S. Environmental Protection Agency (EPA) is soliciting input for a proposal that would revise the rules for project emissions accounting used for determining whether a project modification will require a new source review (NSR) permit. Project emissions accounting includes the process and the calculations stationary sources use to determine whether NSR applies at an existing facility due to a physical change or a change in the method of operation there. The project emissions accounting process requires sources to determine whether the modification will result in an emissions increase that triggers NSR. More information, including the importance for Tribes, can be found in the fact sheet below. You can also learn more about the proposed rule on the EPA’s New Source Review Reform website.
Comments on this proposed rule are due to EPA by July 2, 2024 using the Federal Rulemaking Portal or by email to a-r-Docket@epa.gov. The Docket ID is: EPA-HQ-OAR-2022-0381 (note that the Docket ID was changed from a prior ID number).
