Acting EPA Administrator James Payne sent an email to members of the agency's Science Advisory Board and the Clean Air Scientific Advisory Committee informing them that both are being "reset."

The Trump administration dismissed members of the Environmental Protection Agency’s (EPA) Clean Air Scientific Advisory Committee and Science Advisory Board on Tuesday, a day before the confirmation of new EPA Administrator Lee Zeldin,

Left hanging are EPA reviews of lead, nitrogen oxides and ozone, three pollutants associated with serious health and environmental effects.

Acting EPA Administrator James Payne has ousted all members of two of the agency's most influential science advisory panels, giving President Donald Trump's administration the opportunity to reshape them with its own appointees.

Critics fear the unusual clean sweep of panels is meant to ease the planned rollback of climate and environmental policy.
