This rule protects public health by ensuring timely notification to the public and to public health departments, public drinking water facilities and other potentially affected public entities, including Indian tribes. It provides additional specificity beyond existing public notification requirements to ensure timely and consistent communication to the public regarding CSO discharges to the Great Lakes Basin. Timely notice may allow the public and affected public entities to take steps to reduce the public’s potential exposure to pathogens associated with human sewage, which can cause a wide variety of health effects, including gastrointestinal, skin, ear, respiratory, eye, neurologic, and wound infections.
