The City of Grand Island may adopt requirements identifying Best Management Practices for any activity, operation, or facility which may cause or contribute to pollution or contamination of storm water, the storm drainage system, or waters of the United States of America. The owner or operator of a commercial or industrial establishment shall provide, at the owner or operator’s expense, reasonable protection from discharge of prohibited materials or other wastes into the municipal storm drainage system or watercourses through the use of these structural and nonstructural Best Management Practices. Further, any person responsible for a property or premise, which is, or may be, the source of an illicit discharge, may be required to implement, at said person’s expense, additional structural and non-structural Best Management Practices to prevent the further discharge of pollutants to the municipal separate storm sewer system. These Best Management Practices shall be part of a storm water pollution prevention plan as necessary for compliance with requirements of any National Pollutant Discharge Elimination System permit.
