<br /> (1) Oils and Grease. Total fat, wax, grease or oil concentration
<br />of more than 100 mg/1, whether emulsified or not, or containing substances
<br />which may solidify or become viscous at temperatures between 32° and
<br />150°F (0° and 65°C) at the point of discharge into the system.
<br /> (2) Explosive Mixtures. Liquids, solids or gases which by reasons
<br />of their nature or quantity are, or may be, sufficient either alone or
<br />by interaction with other substances to cause fire or explosion or be
<br />injurious in any other way to the sewerage facilities or to the operation
<br />of the system. At no time shall two successive readings on an explosion
<br />hazard meter, at the point of discharge into the sewer system, be more
<br />than five percent (5%) nor any single reading over ten percent (10%) of
<br />the Lower Explosive Limit (LEL) of the meter. Prohibited materials
<br />include, but are not limited to, gasoline, kerosene, naptha, benzene,
