EPA Region 7 lauds IDNR, local businesses for improving Muscatine air quality; truth is neither deserves credit for clamping down on primary polluter

on Fri, 11/21/2025 - 02:15   by news

The Region 7 administrator for the EPA sent out a news release recently (11/18) patting the back of the Iowa Department of Natural Resources (IDNR) and "local businesses" for reducing SO2 (sulfur dioxide) pollution, enabling Muscatine to achieve compliance with national air quality standards.

Truth is, legal action by the Iowa Attorney General's office (under Democrat Tom Miller) and a civil lawsuit by local residents led to the significant improvement in local air quality and forced the primary polluter – Grain Processing Corporation (owned by Kent Feeds) – to install millions of dollars in new plant equipment to curb SO2 emissions.

Iowa District Court Judge John Telleen gave preliminary approval of the settlement Monday (October 22), concluding six years of litigation over air pollution from the GPC facility.

The number of exceedances of National Ambient Air Quality Standards declined sharply in 2015 compared with 2014, due in large part to reductions in pollution emitted by Grain Processing Corporation's (GPC) corn-milling operations in Muscatine.

According to the Iowa Department of Natural Resources (IDNR) air quality report for 2015, 17 exceedances of the sulfur dioxide ambient air standards were recorded and 8 exceedances of the PM 2.5 (fine particulate) standard.

All 17 SO2 exceedances and one of the eight PM 2.5 exceedances occurred at Muscatine air monitors.
