Final National Level Listed Species Biological Evaluation for Carbaryl
In March 2021, EPA released the final Biological Evaluation (BE) assessing risks to listed species from labeled uses of carbaryl. 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. EPA used these BEs to initiate formal consultation under the Endangered Species Act (ESA) section 7(a)(2) and its implementing regulation at 50 CFR Part 402.46, Optional Formal Consultation Procedures for FIFRA Actions. The final BE was conducted according to the Revised Method for National Level Listed Species Biological Evaluations of Conventional Pesticides.
The final BE for carbaryl is provided below. The models and tools used to conduct this BE can be found here.
EPA solicited public comments on the draft BE for carbaryl, incorporated public comments where appropriate in the final BE, and prepared a response to comments document. Response to Comments on the Biological Evaluations for carbaryl and methomyl (PDF) (78 pp, 887 K)
