"A group of scientists assembled by the EPA to advise it on air pollution standards couldn’t reach agreement on whether the standards should be tightened or remain the same, a development that may complicate ongoing effort to update them.
The Environmental Protection Agency’s Clean Air Scientific Advisory Committee was looking at the current environmental rules for fine particulate matter, also known as PM2.5, during a two-day meeting that ended Oct. 25. Four of the committee’s six members believed the current rules are acceptable, while two others believed they should be lowered to better protect public health.
“We don’t have consensus,” Mark W. Frampton, an emeritus medical professor specializing in pulmonary diseases and critical care at the University of Rochester, said Oct. 25 at the meeting in Cary, N.C. He was one of the two who called for lowering the level allowed in the standard."
