"EPA staffers have tentatively concluded that the agency’s ground-level ozone standards do not need to be strengthened, reaffirming a Trump administration decision on one of the agency’s most closely watched pollutant limits.

In a draft assessment released late yesterday, the career air office employees wrote that they had not found enough new scientific evidence to warrant tightening the current 70-parts-per-billion limit, set in 2015.

That preliminary conclusion is far from the last word. An independent review panel that held its first virtual meeting today will eventually chime in with its own recommendation; a final decision by EPA Administrator Michael Regan is likely more than a year away."
