Carbaryl, Carbofuran, and Methomyl - National Marine Fisheries ...

Evidence Available for the Consultation
We search, compile and use a variety of resources to conduct our analyses including:
• EPA’s BEs, REDs, IREDS, other documents developed by EPA
• Peer-reviewed literature
• Gray literature
• Books
• Available pesticide labels
• Any correspondence (with EPA or others)
• Available monitoring data and other local, county, and state information
• Pesticide registrant generated data
• Online toxicity databases (PAN, EXTOXNET, ECOTOX, USGS, NPIC)
• Pesticide exposure models run by NMFS
• Population models run by NMFS
• Information and data provided by the registrants identified as applicants
• Comments on the draft Opinion from EPA and any applicants
• Incident reports
Collectively, this information provided the basis for our determination as to whether and
to what degree listed resources under our jurisdiction are likely to be exposed to EPA’s
action and whether and to what degree the EPA can ensure that its authorization of
pesticides is not likely to jeopardize the continued existence of threatened and
endangered species or is not likely to result in the destruction or adverse modification of
designated critical habitat.
Application of Approach in this Consultation
The EPA proposes to authorize the use of over 100 pesticide formulations (pesticide
products) containing the a.i.s carbaryl, carbofuran, and methomyl through its authority to
register pesticides under FIFRA. Registration by EPA authorizes the use of these
formulations in the U.S. and its territories, documented by EPA’s approval of registrantderived
pesticide labels. Pursuant to the court’s 2002 order in Washington Toxics
Coalition v. EPA, EPA initiated consultation on registration of carbaryl, carbofuran, and
methomyl for 26 listed ESUs of Pacific salmonids. Since EPA initiated consultation,
NMFS has listed one additional Pacific coho ESU and one additional Pacific steelhead
DPS. This Opinion represents NMFS’ evaluation of whether EPA’s authorization of
