Sen. Tom Carper requested more information from Environmental Protection Agency Administrator Scott Pruitt on the agency’s decision to reverse a ban on the remaining uses of chlorpyrifos, a pesticide used on certain food crops and non-agricultural sites.

Pruitt’s decision goes against the recommendation made by EPA’s scientists in 2015 that called for a total ban on all remaining uses of chlorpyrifos.

“I’m troubled by EPA’s apparent dismissal of the extensive analysis undertaken previously by EPA scientists without providing any new scientific analysis to support this decision,” Carper wrote. “The previous finding to ban chlorpyrifos was based on extensive data, models and research developed by industry, government and academic scientists. Absent such justification, this decision to lift the proposed ban could undermine the trust the public has in the agency to keep its food, water and air safe.”
