9th Circuit Orders EPA to Reconsider Petition to Ban Dangerous Pesticide Flea Killer

The Ninth Circuit has ordered the Environmental Protection Agency to revisit a petition submitted by the Natural Resource Defense Council asking the agency to ban the use of tetrachlorvinphos in flea collars for companion animals. A unanimous panel found the agency failed to provide a “reasoned explanation” for its denial of the petition and ordered the agency to respond again within 120 days.
