EPA Extends Comment Period for the National Marine Fisheries Service’s Biological Opinion on Chlorpyrifos, Diazinon, and Malathion

In response to numerous requests, EPA is extending the public comment period on the National Marine Fisheries Service’s Biological Opinion on chlorpyrifos, diazinon, and malathion. Please submit comments by July 23, 2018, to the docket EPA-HQ-OPP-2018-0141 at regulations.gov. EPA will share all public comments received on this Biological Opinion with NMFS, and EPA will evaluate them before determining how to proceed.

EPA is seeking comment on the NMFS’s Biological Opinion for chlorpyrifos, diazinon and malathion in accordance with EPA’s public stakeholder process for ESA consultations – an open and transparent process supported by the Services, EPA, and USDA. Stakeholder input is critical to the development of any measures EPA may implement to address risks to listed species and designated critical habitat.  Continue reading

EPA Releases Final Biological Evaluations of Three Chemicals’ Impacts on Endangered Species

The Environmental Protection Agency has released its final biological evaluations (BEs) for effects of chlorpyrifos, diazinon, and malathion on threatened and endangered species and their designated critical habitat. We have also released a separate document that addresses the comments submitted during the public comment period.

Under the Endangered Species Act, for those species and designated critical habitats where registered uses of the three pesticides are “likely to adversely affect” the species and/or their habitat, U.S. Fish and Wildlife Service and the National Marine Fisheries Service will incorporate the analyses and data from EPA’s biological evaluations into their final Biological Opinions for each of the three chemicals.  Continue reading

EPA Extends Comment Period for Malathion Assessment

The Environmental Protection Agency is extending the public comment period for the draft malathion human health risk assessment.  The availability of the draft assessment for this organophosphate pesticide was originally announced on September 15, 2016.  The comment period will now close on December 21, 2016.

Read the September 15 announcement.

EPA holds 2-day workshop on biological evaluations

On June 29 and 30, 2016, the Environmental Protection Agency and its federal partners, Fish and Wildlife Service, National Marine Fisheries Service, and U.S. Department of Agriculture, will hold a two-day workshop. This workshop will offer a forum for stakeholder suggestions for refining some of the interim scientific methods used in the recently released draft Biological Evaluations (BEs) for three pilot chemicals: chlorpyrifos, diazinon, and malathion. These BEs are the first nationwide endangered species risk assessments. They were developed by EPA, FWS, and NMFS (with collaboration from USDA on crop production, use, and geospatial data on agricultural use patterns) in response to the 2013 National Academy of Sciences (NAS) report entitled, “Assessing Risks to Endangered and Threatened Species from Pesticides.”   Continue reading

Save the Date & Register for Technical Webinar on Recently Released Endangered Species Assessments

On May 5, 2016, from 1:00 to 3:00 PM Eastern Time, EPA will hold an online technical briefing on the first-ever draft biological evaluations analyzing the nationwide effects of chlorpyrifos, diazinon and malathion on endangered and threatened species and designated critical habitat. Register for the webinar at https://epawebconferencing.acms.com/esapilotbioevals/event/registration.html. Continue reading

Supporting Documents for Endangered Species Biological Evaluations Now Available

Background documents for the first round of draft biological evaluations are now available for three pilot chemicals: chlorpyrifos, diazinon, and malathion. The Environmental Protection Agency has been collaborating with the U.S. Fish & Wildlife Service and the National Marine Fisheries Service to develop interim scientific approaches to fulfill our responsibility under the Endangered Species Act to assess the impact of pesticides on threatened and endangered species and their designated critical habitat. These interim scientific approaches are based on recommendations from the National Academy of Sciences report, “Assessing Risks to Endangered and Threatened Species from Pesticides.” As part of this effort, the United States Department of Agriculture has provided expertise on crop production and pesticide uses and assistance with the use of the National Agricultural Statistics Service Cropland Data Layer to help define the footprint of agricultural use patterns.

Organophosphate and ADHD Study: More Questions than Answers

For years, scientists have looked for causes for a childhood disorder that is becoming more common among young children: attention deficit hyperactivity disorder (ADHD). Medical studies have cited several possible causes, from diet to environmental factors. A new study released in May adds organophosphate pesticide exposure to the list.
