Exceptional Events Rule Resources


The Exceptional Event Rule (EER) provides a way for states to flag air quality data for possible exclusion when NAAQS compliance is determined, provided the EPA concurs with the supporting documentation, and the event contributing to the data meets certain criteria. Exceptional Events are those events that impact air quality but are not reasonably controllable, and not likely to reoccur. Wildland fires are among the exceptional events states flag under this rule.

On September 16, 2016 the EPA finalized its revisions to the 2007 Exceptional Events Rule. EPA's webpages and documents outlining the new rule, guidance, and other resources are listed below.

Ozone


 

In October 2015 the EPA strengthened the National Ambient Air Quality Standards for ozone to 70 parts per billion. This new standard will have implications for the wildland fire community. This page highlights regulatory information from the EPA, maps of potential non-attainment areas, testimonies, and the latest reports and research collected by the NWCG Smoke Committee.

EPA Materials

The EPA ozone standards page contains the final rule, memo for implementing the new standard, regulatory impact analysis, maps and tables, fact sheets, and technical documents. These are individually listed below:

Front cover of the proposed revised regional haze ruleProposed Revisions to the Regional Haze Rule

On April 25, 2016 , the U.S. Environmental Protection Agency (EPA) proposed revisions to the Regional Haze Rule, which describes actions that states must take when submitting regional haze state implementation plans SIPs) and progress reports.

On June 30th the document 'Draft Guidance on Progress Tracking Metrics, Long-term Strategies, Reasonable Progress Goals and Other Requirements for Regional Haze State Implementation Plans for the Second Implementation Period was released for comment. When final, the document is expected to complement the revision of the Regional Haze Rule.
