"In a new draft document, the Environmental Protection Agency’s (EPA) science advisers recommended that the agency tighten its air quality standards for soot pollution after the Trump administration declined to make such a move.

The new draft that was released Friday by the EPA’s Clean Air Scientific Advisory Committee (CASAC) says “all CASAC members agree that the current level of the annual standard is not sufficiently protective of public health and should be lowered.”

In late 2020, the Trump administration declined to tighten the standard for soot pollution, leaving it at the level finalized under the Obama administration."
