My clients in Minnesota are pleased that after years of litigation and the continued reliance upon expired industrial stormwater rules that Minnesota now has new rules. They may not be as pleased to see that the rules include additional regulatory steps, including as a key component the requirement to “shelter” pollutant containing materials from exposure to stormwater. For ethanol plants this generally translates to taking steps to better control dust exiting both the grain receiving areas and DDG storage.
