Draft National Level Listed Species Biological Evaluation for Methomyl
In March 2020, EPA released the draft Biological Evaluation (BE) assessing risks to listed species from labeled uses of methomyl. 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 endangered species risk assessment process. 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, through the docket on the draft BEs for chlorpyrifos, diazinon and malathion, and through the docket on the proposed Revised Method; comments received during consultation with federally recognized tribes; and comments provided by U.S. Fish and Wildlife Service, National Marine Fisheries Service and the US Department of Agriculture. The draft BE for methomyl is provided below.
Commenters are instructed to post comments to the BE docket (see EPA-HQ-OPP-2020-0090 at www.regulations.gov). The docket will be open for comment for 60 days after the Federal Register Notice (FRN) (FRL-10006-38) announcing the availability of the draft BEs. View the prepublication notice of the biological evaluation for carbaryl and methomyl. Additional information for commenters, including specific aspects of the draft BEs for which the EPA is seeking comment, will be available in the FRN.
