The state has a year and a half to put together a plan to address air quality issues in Muscatine. The U.S. Environmental Protection Agency announced on Friday that the Muscatine area is not meeting air quality standards for sulfur dioxide. Iowa has 18 months to submit a State Implementation Plan that shows how they’ll meet standards over the next 5 years.

Emissions from a MidAmerican Energy facility in Louisa County was among eight sources cited by the EPA as contributors to the high sulfur dioxide levels.

Air containing high levels of the pollutant can cause breathing difficulties and an increase to asthma symptoms.
