Interagency Wildland Fire Chemicals Policy and Guidance

Retardant drop over Cove Creek Fire

Aerially applied fire retardant and other fire chemicals reduces wildfire intensity and rate of spread, decreasing risks to firefighters, enabling them to construct fireline safely. In many situations, the use of retardant in concert with firefighters on the ground allows the Forest Service to safely meet its responsibilities to protect landscapes, resources, and people.


Nationwide Aerial Application of Fire Retardant on National Forest System Lands

In 2011 the FS signed a Record of Decision implementing direction for the Nationwide Aerial Application of Fire Retardant. In 2020 the FS reviewed new information, published in the 2020 Supplemental Information Report. That report recommended modification of the proposed action that was selected in 2011 and implemented in 2012, and preparation of a Supplemental Environmental Impact Statement. The draft Supplemental Environmental Impact Statement has been completed and is available below for review.
