EPA Proposes Changes in Chlorpyrifos Regulation

The Environmental Protection Agency (EPA) is extending the use of the pesticide Chlorpyrifos for some purposes in a proposed interim decision and associated risk assessments, which are open to public comment for 60 days.
Specifically, EPA is proposing: label amendments limiting application to address potential drinking water risks of concern; additional personal protection equipment and application restrictions to address potential occupational handler risks of concern; and spray drift mitigation, in combination with the use limitations and application restrictions identified to address drinking water and occupational risks, to reduce exposure to non-target organisms.
EPA will also consider the input and recommendations from the September 2020 FIFRA Scientific Advisory Panel (SAP) meeting once it releases its report in December 2020. Depending on the SAP’s conclusions, EPA may further revise the human health risk assessment. After a thorough review of the best available science and carefully considering scientific peer review and public comments, EPA will then determine next steps in the registration review process for chlorpyrifos.
