Des Moines Register: Over the past three years, two Iowa companies have repeatedly told the state and federal governments they’ve exceeded the amount of pollution they can discharge into the Mississippi and Missouri rivers, a national environmental group says. Yet amid cuts to environmental agencies, it says, no action has been taken against them. In a report released Wednesday, the Environmental Law & Policy Center blames the lack of enforcement on President Donald Trump, who has slashed the spending and staffing needed to enforce the federal Clean Water Act. That’s left companies such as ADM Bioprocessing in Clinton and Gelita USA in Sergeant Bluff to rack up dozens of violations since 2017 without facing any formal enforcement action, the Chicago-based group’s report says.
