The BLM signed the Record of Decision for the Final Programmatic Environmental Impact Statement National Vegetation Treatments Using Aminopyralid, Fluroxypyr, and Rimsulfuron (Final PEIS) on BLM Lands administered lands on August 15, 2016.  The Final PEIS provides a cumulative impact analysis addressing the use of chemical herbicides in conjunction with other treatment methods, addressing human health and ecological risks for the use of these three active ingredients (herbicides) on public lands. The 2016 Final PEIS includes an updated analysis per the National Environmental Policy Act (NEPA) compliance document on the effects of using herbicides for treating vegetation on public lands in the western U.S., including Alaska.  

The ROD outlines the approval for the use of three additional EPA registered herbicide active ingredients on all 17 states assessed in the Final PEIS: aminopyralid, fluroxypyr, and rimsulfuron.  The Human Health and Ecological Risk Assessment prepared for the Final PEIS can be found on the BLM Web Site under the Weeds and Invasives Heading. Also available are the two new risk assessment documents, for 2, 4-D and clopyralid, that provide the field offices (FOs) updated information to be used in conjunction with their NEPA analysis when including the two active ingredients in their vegetation management plans.  

The Final PEIS considered vegetation treatment activities, including noxious weed and invasive terrestrial plant species management, hazardous fuels reduction treatments, emergency stabilization and rehabilitation efforts. The Final PEIS tiers to the 2007 Final Vegetation Treatments Using Herbicides on the Bureau of Land Management Lands in 17 Western States PEIS (2007 PEIS) and the Programmatic Environmental Report (PER).
