Transcript: Ozone standards
Iowa is one step ahead of new national ozone emission standards.
This is the Iowa Environmental Focus.
In November, the U.S. Environmental Protection Agency released a draft proposal to drastically reduce ozone emissions from power plants and other sources by 2025. All 99 of Iowa’s counties are set to meet the new standards, according to data collected by the Iowa Department of Natural Resources.
The EPA’s Clean Air Scientific Advisory Committee earlier this year recommended ozone levels be reduced to between 65 and 70 parts per billion, down from the current practice of 75 parts per billion.
Iowa already meets the EPA standards, with monitoring stations showing average ozone levels between 61 and 69 parts per billion. The Iowa DNR supplies data to the EPA’s Air Quality Index, which provides air quality conditions in real time.
