EPA proposes tightening primary ozone standards to range of 65-70 ppb; final rule by October 2015

Green Car Congress

NOVEMBER 26, 2014

Counties where measured ozone is above proposed range of standards, based on 2011-2013 monitoring data. Earlier this year, EPA staff had recommended the further reduction of this primary ozone standard from the current 75 ppb (parts per billion) to a revised level within the range of 70 ppb to 60 ppb—and preferably below 70 ppb.

The proposed Transport Rule sets in place a new approach that can and will be applied again as further pollution reductions are needed to help areas meet air quality health standards, EPA says. This proposal reduces emissions contributing to fine particle (PM 2.5 ) and ozone nonattainment that often travel across state lines.
