Status of Exceptional Events

Current Policies for Exceptional Events and Natural Events 1996 PM-10 Natural Events Policy 1986 Exceptional Events Policy 1998 Interim Air Quality Policy on Wildland and Prescribed Fires

Current Polices on Exceptional Events and Natural Events Continued The Exceptional Events Policy covers both Exceptional Events and Natural Events issues for all of the criteria pollutants. There is one exception: The PM-10 Natural Events Policy covers Wild fires, high wind events, and emissions from volcanic and seismic activities for PM-10.

Current Polices on Exceptional Events and Natural Events Continued Wildland and Prescribed Fires issues are covered under the 1998 Interim Wildland and Prescribed Fire Policy. Natural Events issues for PM-2.5 will be handled on an interim basis under the PM-10 Natural Events Policy. 8-hour Ozone issues related to fire and natural events issues will be handled under the Exceptional Events Policy the same as the 1 hour Ozone NAAQS.

Next Steps on Exceptional Events and Natural Events Policies OAQPS plans to review the need to update the Exceptional Events and Natural Events Policies. At present, we are just in the beginning stages of reviewing the need to revise the policies. We encourage States to continue to follow the current policies.
