Endangered Species Effects Determinations, Consultations, and Biological Opinions

Consistent with EPA’s mission to present science in an open and transparent manner, the Agency makes available on this site, litigation-related assessments and effects determinations for listed species. In the event that future actions are taken by the courts, and as EPA completes additional litigation-related assessments and effects determinations, these documents will be posted to this site as well. The science documents below show litigation-related pesticide assessments and effects determinations for listed species. Supporting documents cited in the assessments and effects determinations are listed below the assessment or effects determination. Other supporting documents, such as reregistration eligibility decisions (REDs), may be found in the regulatory action tab for the specific chemical.

EPA's primary priority-setting approach continues to be its registration and registration review programs. Assessments and effects determinations made consistent with the registration and registration review programs can be found in the regulatory action tab for the specific chemical.
