Exceptional Events
Overview
The purpose of the exceptional events rule is to ensure that regulatory decisions under the Clean Air Act are not biased by monitored air quality data over which a state has little or no control.
EPA September 2016 Final Rule and Guidance
App for Creating Exceptional Event Demonstrations
WESTAR/WRAP is coordinating an effort lead by staff at the South Coast Air Quality Management District (SCAQMD) to develop an online app to assist air agencies in preparing an Exceptional Events (EE) Demonstration for submission to the EPA. This interactive app lays the ground work for automating much of the technical data collection required in Exceptional Event Demonstrations. The online tool is a collaborative project among air quality regulatory agencies across the Nation. It is, and will continue to be, a work in progress. If you are interested in contributing to this project, please contact Rhonda Payne at WESTAR or Jay Baker at WESTAR.
To see a demonstration of the app, you can view this recording from a recent MARAMA meeting.
While use of this app in no way guarantees EPA concurrence for any EE demo submitted to the EPA, we are working with them to make sure the outputs meet the requirements of the EE rule. EE demos created using this app will be subject to the same review process as EE demos that do not use this app.
