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.
