Draft National Level Listed Species Biological Evaluation for Glyphosate

In November 2020, EPA released the draft Biological Evaluation (BE) assessing risks to listed species from labeled uses of glyphosate. (Listed species refers to those that are federally listed as endangered or threatened, as well as experimental populations and those species that are proposed and candidates for listing).

The draft BE was conducted according to the Revised Method for National Level Listed Species Biological Evaluations of Conventional Pesticides.   

The Revised Method described in this document incorporates:

  • Recommendations from the National Research Council of the National Academy of Sciences (NAS);
  • EPA’s “lessons learned” during the first three pilot BEs;
  • Public comments provided through
    • Stakeholder meetings,
    • The docket on the draft BEs for chlorpyrifos, diazinon and malathion, and 
    • The docket on the proposed Revised Method;
  • Comments received during consultation with federally recognized tribes; and
  • Input provided by U.S. Fish and Wildlife Service, National Marine Fisheries Service and the U.S. Department of Agriculture.

The Draft BE for glyphosate is provided below. The models and tools used to conduct this BE can be found here.

Commenters are instructed to post comments to the BE docket (see EPA-HQ-OPP-2020-0585 at www.regulations.gov). The docket will be open for comment for 60 days after the Federal Register Notice (FRN) (FRL-10017-03) announcing the availability of the draft BEs. View the prepublication notice of the biological evaluation for glyphosate. Additional information for commenters will be available in the FRN.
