(11)
A statement as to why the generator believes it qualifies for an exemption; and

The appeal shall be to the city council and shall include any evidence the generator wishes to provide that the required pumping of grease traps or grit traps is not necessary. The decision of the city council shall be final. |

Diversion of wastewater.
No grease generator or grit generator shall divert wastewater around a collection point into the sanitary sewer or into a storm drainage system.
(f)
