EPA Study On Particulate Matter Controls Finds Substantial Benefits

A major new EPA study of the benefits of particulate matter (PM) controls suggests that costly air quality regulations -- like the Clean Air Interstate Rule and diesel rules -- surpass by three times the threshold for being considered cost-effective.

The finding could give agency officials leeway to argue for strict regulatory requirements because they can justify the high costs the regulations may impose on regulated entities.

An EPA science policy group is putting the finishing touches on two guidance documents that will standardize the age-range groups the agency uses to study exposure to environmental toxins and outline cancer susceptibility from early-life exposures.
