EPA Provides Information About Reducing Pesticide Impacts on Endangered Species

This original announcement was published by the EPA on September 23, 2020. Click here for more!


EPA is providing materials to help the public and pesticide applicators protect endangered species and their critical habitats.

Information on possible risk reduction measures, such as best management practices to reduce exposures and impacts to federally threatened and endangered species, can now be found on our website.

These materials came out of EPA’s consultation with the National Marine Fisheries Service (NMFS) on registrations of pesticide products containing the insecticides chlorpyrifosdiazinon and malathion.

In December 2017, NMFS issued a final biological opinion on these three chemicals as part of a consultation process. Read the biological opinion here. A biological opinion provides a view of whether the pesticide’s registered use is likely to jeopardize a species, and if so, describes alternatives to avoid jeopardy.

EPA re-initiated consultation with NMFS to allow for consideration of additional information. The Agency remains in consultation with NMFS as they revise their biological opinion.

Additional information on the re-initiated consultation is available on with the docket number EPA-HQ-OPP-2018-0141.
