If, in the opinion of the Supervisor of Sewage Treatment, or his or her agent, a load of waste material is unfit or unsafe for discharge in the city’s sewage disposal system, the Supervisor of Sewage Treatment or his or her agent may refuse to permit such discharge or dumping. Under no condition shall permission be given to discharge or dispose of the cleanings from grease and oil and similar interceptors. In the event any such permission to discharge or dump is refused, any permit fee paid therefor shall be refunded upon written application therefor made to the Director of Utility Services.
