EPA Prepares to Ban Chlorpyrifos

Written by Tyler R. Etter

On October 30, 2015, the Environmental Protection Agency (EPA) opened for commenting a proposal to revoke all tolerances for the insecticide chlorpyrifos. The proposal is being issued pursuant to a court order from August of 2015.

Originally, the EPA planned to issue the proposed rule by April of 2016, but the 9th Circuit ordered the Agency to deny the petition issued for a safety evaluation, issue a proposal, or issue a final rule by October 31, 2015. Due to the Agency being unable to make a safety finding, and questions in scientific assessment still being open, the EPA has issued the proposal.

The proposal will seek to revoke all food residue tolerances for chlorpyrifos. Under current analysis, there does not appear to be a risk from exposure to chlorpyrifos from food. However, the Agency cannot make a conclusion about the aggregate exposure between food residue and exposure from drinking water in affected watersheds.

The comment period is open until January 5, 2016. The EPA expects to release a final rule by December of 2016. The proposed rule can be read and commented on here.
