The majority of Ohio counties face “an urgent threat” from the U.S. Environmental Protection Agency (EPA)’s plan to tighten ozone limits, says an advocacy group’s recently released study, Gongwer reports. The report, “Powering Down: How Washington’s Ozone Plan Will Snuff Out Ohio’s Economic Recovery,” commissioned by the Center for Regulatory Solutions, says that “85% of Ohio’s economy along with thousands of jobs will be negatively impacted by the plan.” The proposed EPA rule calls for “the lowering of National Ambient Air Quality Standards from 75 parts per billion to between 65 and 70 ppb.” This would put 34 Ohio counties, including counties in the Cleveland and Cincinnati areas, out of compliance and necessitate air quality improvements. The American Lung Association director of advocacy Shelly Kiser called the findings “scare tactics,” saying, “[t]he science is clear: the current limit, or standard, on ground-level ozone protection is too out-of-date and too weak to protect our families’ health.” Kiser said the updated standard will decrease asthma attacks and hospitalizations for Ohio’s 257,000 children and 867,000 adults with asthma, and may even save lives.
