(NPR) - Update 7:06 P.M. Eastern: The EPA says it's reversing course and keeping this pesticide on the market.

That's despite the agency's earlier conclusion, reached during the Obama administration, that chlorpyrifos could pose risks to consumers. It's a signal that toxic chemicals will face less restrictive regulation by the Trump Administration.

In its decision, the EPA didn't exactly repudiate its earlier scientific findings. But it did say that there's still a lot of scientific uncertainty about the risks of chlorpyrifos, and it said that because of that uncertainty, the court had no right to set a firm deadline for a decision.

The EPA says it will keep studying the chemical.

Patti Goldman, from the environmental group Earth Justice, calls the decision "unconscionable," and says that her group will fight it in court.
