Environmental Protection Agency Registration of Pesticides Containing Chlorpyrifos, Diazinon, and Malathion: Biological Opinion

摘要

This Opinion is based on NMFS review of the package of information the EPA submitted with its 2002, 2003, and 2004 requests for formal consultation on the proposed authorization of the active ingredients. It also includes our review of recovery plans for listed Pacific salmonids, past and current research and population dynamics modeling efforts, monitoring reports from prior research, biological opinions on similar research, published and unpublished scientific information on the biology and ecology of threatened and endangered salmonids in the action area, and other sources of information gathered and evaluated during the consultation on the proposed authorization of active ingredients for chlorpyrifos, diazinon, and malathion. NMFS also considered information and comments provided by EPA and by the registrants identified as applicants by EPA.
