In October 2015, the Obama administration proposed to revoke all food residue tolerances for chlorpyrifos, an active ingredient in insecticides.
EPA Administrator Scott Pruitt said:
"We need to provide regulatory certainty to the thousands of American farms that rely on chlorpyrifos, while still protecting human health and the environment,"
Pruitt said in a statement. "By reversing the previous administration’s steps to ban one of the most widely used pesticides in the world, we are returning to using sound science in decision-making — rather than predetermined results."
He argued that the "public record lays out serious scientific concerns and substantive process gaps in the proposal".
