Iowa's largest ethanol producer – POET, LLC – has agreed to fines totaling $53,000 for hazardous air emissions from its Shell Rock refinery over a two-year period.

The Iowa Department of Natural Resources (IDNR) imposed a $10,000 fine – the most the department is allowed to levy without submitting the case to the Iowa Attorney General's office – and assessed a $43,000 fee – or $70 per ton for the more than 600 tons of volatile organic compounds (VOC's) the plant released during 2021 and 2022.

The ambient air quality standard for ozone was lowered to 70 ppb from 75 ppm last December.
