The demise removes a group of experts that could have probed the air quality impacts of the Trump administration’s deregulatory blitz.

EPA is abolishing a decades-old advisory panel that provided a rare public forum for outside experts to scrutinize the work of the agency’s efforts to address air pollution.

As President Donald Trump continues a wave of regulatory rollbacks, the Clean Air Act Advisory Committee’s demise removes one body that could have probed the impacts on air quality programs.

The committee is among at least four EPA advisory panels scrapped thus far during Trump’s second term following a White House downsizing directive. EPA is also axing a related air pollution panel, the Mobile Sources Technical Review Subcommittee, which provided independent advice and recommendations on tailpipe and motor fuel regulations.
