The Environmental Protection Agency and Army Corps of Engineers are formally repealing the 2015 “waters of the U.S.” rule in advance of publishing a new WOTUS rule around the end of the year.

The 9th Circuit Court of Appeals has given the Environmental Protection Agency 60 days to revoke all food tolerances and cancel all registrations for the widely used insecticide chlorpyrifos.

The Senate has unanimously passed a bill to reauthorize the Pesticide Registration Improvement Act, which allows the Environmental Protection Agency to charge fees for pesticide registration that fund about one-third of the operations of the Office of Pesticide Programs.

Forest biomass is carbon neutral, EPA Administrator Scott Pruitt said today, announcing a decision that cheered private forest owners but inflamed environmentalists.

Once again, a budget deadline is approaching with serious implications for EPA's fee-based pesticide registration program, which has been kept alive with stopgap funding bills since the federal fiscal year ended Sept. 30.

Democratic senators led by New Mexico's Tom Udall want answers from EPA on chlorpyrifos and farmworker protections from pesticides before they'll agree to let a bill move forward reauthorizing the fee-based pesticide registration system that provides about a third of the funding for EPA’s Office of Pesticide Programs.
