Pesticide Consultations with EPA

Joint Stakeholder Workshop

The Environmental Protection Agency, U.S. Department of Agriculture, U.S. Fish and Wildlife Service, and NOAA Fisheries held a stakeholder workshop on November 15, 2013 to discuss and take comment on interim scientific approaches to address National Academy of Sciences (NAS) recommendations for assessing risks from pesticides to endangered and threatened species. Materials for the workshop are also available.

Background

The Environmental Protection Agency (EPA) is consulting with NMFS' Office of Protected Resources for re-registering 37 pesticide active ingredients.


ESA-Listed Salmonids Map:
28 Evolutionarily Significant Units

As part of a court settlement with the plaintiff, Northwest Coalition for Alternatives to Pesticides (NCAP) [pdf], we agreed to complete biological opinions for the 37 active ingredients, with final deadlines specified for different batches of pesticides (see schedule).

All opinions for these active ingredients are to be completed on or before June 30, 2013.

Biological Opinions

NMFS has completed six opinions addressing 27 active ingredients. Three opinions (1-3) consider organophosphate (OP) and carbamate insecticides. The fourth opinion (4) considers 4 herbicides and 2 fungicides. The fifth opinion (5) considers 3 herbicides. The sixth (6) opinion considers thiobencarb. A summary of the opinions is available on our website.

  1. EPA posts to their docket NOAA Fisheries' draft Endangered Species Act Section 7 Consultation Conference and Biological Opinion on the registration of three insecticides: Diflubenzuron, Fenbutatin Oxide, and Propargite
  1. Thiobencarb
    On July 2, 2012, NMFS issued a final biological opinion concluding that EPA’s registration of herbicide thiobencarb is not likely to jeopardize the continued existence of three listed Pacific salmonid Evolutionary Significant Units/Distinct Population Segments or adversely modify their designated critical habitat.

    We analyzed EPA’s registration of thiobencarb based on its authorized use on rice. California is the only state within the range of listed Pacific salmonids that has approved the use of thiobencarb, and use is only approved for rice. As a result, this biological opinion focuses on three listed Pacific salmon Evolutionary Significant Units/Distinct Population Segments located in California’s Central Valley where rice is grown. Re-initiation of this consultation will be necessary if thiobencarb is approved for use by other states with listed Pacific salmonids, or if thiobencarb use expands to any other parts of California within the range of listed Pacific salmonids.
  1. Oryzalin, pendimethalin, and Trifluralin
    On May 31, 2012, NMFS issued a final biological Opinion addressing the effects of dinitroanaline herbicides on listed Pacific salmonids.

    NMFS concluded that oryzalin, pendimethalin, and trifluralin are likely to jeopardize the continued existence of some listed Pacific salmonids, and adversely modify designated critical habitat of some listed salmonids.

  1. Captan, chlorothalonil, 2,4-D, diuron, linuron, and triclopyr BEE
    On June 30, 2011, NMFS issued a final biological opinion addressing the effects of four herbicides (2,4-D, triclopyr BEE, diuron, linuron) and two fungicides (captan, chlorothalonil) on listed Pacfic salmonids. NMFS's conclusions are that:
    • pesticide products containing 2,4-D are likely to jeopardize the continued existence of all ESUs/DPSs of listed Pacific salmonids and adversely modify designated critical habitat for some ESUs/DPSs
    • pesticide products containing chlorothalonil or diuron adversely modify designated critical habitat for some some ESUs/DPSs
    • pesticide products containing captan, linuron, or triclopyr BEE do not jeopardize the continued existence of any ESUs/DPSs of listed Pacific salmonids or adversely modify designated critical habitat
  1. Azinphos-methyl, Dimethoate, Disulfoton, Ethoprop, Fenamiphos, Methamidophos, Methidathion, Methyl parathion, Naled, Phorate, Phosmet, Bensulide [pdf]
    (August 2010)
    NMFS concluded that pesticide products containing Azinphos methyl, disulfoton,fenamiphos, methamidophos, or methyl parathion are not likely to jeopardize the continuing existence of any listed Pacific Salmon or destroy or adversely modify designated critical habitat.

    NMFS also concluded that the effects of products containing bensulide, dimethoate, ethoprop, methidathion, naled, phorate, or phosmet are likely to jeopardize the continued existence of some listed Pacific Salmonids and to destroy or adversely modify designated habitat of some listed salmonids.
  1. Carbaryl, Carbofuran, and Methomyl [pdf]
    (April 2009)
    NMFS concluded that pesticide products containing carbaryl, carbofuran, and methomyl are likely to jeopardize many populations of ESA-listed Pacific salmonids and destroy or adversely modify designated critical habitat. Response to the Opinion:
  1. Chlorpyrifos, Diazinon, and Malathion [pdf]
    (November 2008)
    These three chemicals are components of insecticides used in both agricultural and urban settings. The opinion concluded that these chemicals are likely to jeopardize 27 populations of salmon on the West Coast listed under the Endangered Species Act. Response to the Opinion: Litigation:

Status of Efforts to Implement the Recommendations of the NAS Report on Ecological Risk Assessment for Endangered and Threatened Species under FIFRA and ESA

In April 2013, the National Academy of Sciences' National Research Council released their recommendations for assessing risks from pesticides to listed species under the Endangered Species Act and the Federal Insecticide, Fungicide, and Rodenticide Act.

The Environmental Protection Agency, U.S. Department of Agriculture, U.S. Fish and Wildlife Service, and NOAA Fisheries are working collaboratively and expeditiously to review the report and identify improvements in the current scientific procedures used in evaluating the potential impacts of pesticides to endangered and threatened species. The Federal agencies will develop an implementation plan to provide a timeline and approach for responding to the panel's recommendations and implementing the appropriate revisions to these procedures and approaches. The plan will be available to the public.
