The Environmental Protection Agency on Friday announced a broad reorganization as part of the Trump administration’s drive to cut costs that some activists worry will harm the agency’s independent scientific research.

Administrator Lee Zeldin announced changes that included creating a new unit within his office “to align research and put science at the forefront of the agency’s rulemakings.” He said the overall reorganization would boost efficiency and save at least $300 million annually, though he didn’t detail how the money would be saved.

Though Zeldin didn’t mention it by name, some scientists and activists saw it as an attack on EPA’s Office of Research and Development, which has long provided the scientific underpinnings for EPA’s mission to protect the environment and human health. The agency said it would shift “its scientific expertise and research efforts to program offices” that focus on major issues like air and water.

Separately on Friday, President Donald Trump unveiled a proposed budget to cut that office’s funding by $235 million.
