“Are there Ohio EPA regulations concerning grease-contaminated stormwater? Grease is considered a pollutant. Under Ohio’s water pollution control laws, a business cannot discharge any pollutant into waters of the state without obtaining a permit from Ohio EPA. Waters of the state include streams, rivers, lakes, ponds, marshes, watercourses, waterways, and springs. The requirement also applies to conveyances, such as ditches and storm sewers that drain to waters of the state. Therefore, unauthorized discharges of grease-contaminated stormwater into storm drains or waters of the state are illegal.”
