(e) Beginning June 1, 2015 the maximum monthly total extra strength surcharge to be paid shall not exceed five hundred dollars ($500.00) for any wastewater discharge not located in an I-1, I-2, or I-O zoning district as set forth in the fee schedule located in Part Two - Title Twelve, Chapter 298 of these Codified Ordinances.
