ethanol plant emissions

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.
