(b) Exceed 40 degrees Celsius or 104 degrees Fahrenheit at the POTW treatment plant unless the Commissioner, upon request of the POTW, approves alternate temperature limits.
(2) Any waters or wastes containing more than 100 milligrams per liter of grease, oils, fats or waxes;
(3) Any gasoline, benzene, naphtha, fuel oil, mineral oil, nonbiodegradable cutting oil or nay other flammable or explosive solid, liquid or gas in an amount that could cause interference or pass through;
(4) Any noxious or malodorous gas or substance which either alone or by interactions with other wastes, is capable of creating a public nuisance or hazard to life or of preventing entry into the sewers for their maintenance or repair;

Specifically excluded are any substances in concentrations or amounts exceeding the limitations, set forth by the Town Council and published herein;
