Informational Webinar on Identifying Additional Areas Subject to Mitigation Plan Requirements Under the 2016 Exceptional Events Rule

On April 27, 2022, EPA notified air agencies in four states that under the 2016 Exceptional Events Rule, they will need to develop mitigation plans for certain areas within their states. These areas are experiencing recurring exceptional events that impact air quality and public health. At the same time, EPA issued a Notice of Availability (NOA) making the public aware of this notification. The states will have two years to complete and submit these plans to EPA.

EPA ensures these plans are complete and that the submitting air agency followed the public comment process. If EPA deems the mitigation plans to be complete, air agencies, can submit, and EPA can approve, future demonstrations for the area for the same event type and National Ambient Air Quality Standard combination.

On May 19, 2022, EPA held an informational webinar offering an overview of the process the Agency followed to identify additional areas subject to mitigation plan requirements and a discussion of the required mitigation plan components.
