Below is an excerpt from an article at the Rural County Representatives of California website.
“The U.S. Environmental Protection Agency has released its draft amendments to the Exceptional Events Rule, and have included as a companion a draft Guidance on Preparing Exceptional Events Demonstrations for Wildfire Events that May Influence Ozone Concentrations (Guidance). The Guidance provides methodology for air agencies to differentiate wildfire events from other planned fire events, such as prescribed burns, and to make the preparation and demonstration for these events more efficient.
The Guidance has been released in response to concerns by stakeholders, including RCRC, that the National Ambient Air Quality Standards for ozone finalized earlier this year will essentially eliminate the use of prescribed burning as a method of fuels treatment in forest management projects. The Exceptional Events Rule (Rule) allows for local and state air agencies to demonstrate events that they feel should be excluded from air quality data in their regulatory decisions. Comments on the Rule amendments and draft Guidance are due by January 19, 2016, and can be accessed here.”
