<br /> 1) Any liquids, solids or gases which by reason of their
<br /> nature or their quantity are, or may be, sufficient
<br /> either alone or by interaction with other waste
<br /> substances to cause fire or explosion or be injurious to
<br /> the POTW or the operation of the POT4Y in any other
<br /> way. At no time shall two successive readings on an
<br /> explosion hazard meter, at the point of discharge into
<br /> the system (or at any point in the system) be more
<br /> than five percent (5 0) nor any single reading over ten
<br /> percent (10$) of the lower explosive limit (LEL) of the
<br /> meter. Prohibited materials include, but are not
<br /> limited to, gasoline, kerosene, naphtha, benzene,
<br /> toluene, xylene, ethers, alcohols, ketones, aldehydes,
<br /> peroxides, chlorates, perchlorates, bromates, carbides,
<br /> hydrides and sulfides and any other substances which
<br /> the City, the state and/or the EPA has notified the
<br /> user is a fire hazard or a hazard to the system or
<br /> which the label states to be a flammable substance.
<br /> 2) Solid or viscous substances which may cause
<br /> obstruction to the flow in a sewer or other
<br /> interference with the operation of the wastewater
<br /> treatment facilities such as, but not limited to:
<br /> grease, fat or oil in excess of specific limitations set
<br /> by this ordinance, garbage with particles sized larger
<br /> than one-half inch (Z°) in any dimension, animal guts
<br /> or tissues, paunch manure, bones, hair, hides or
<br /> fleshings, entrails, whole blood, feathers, ashes,

<br /> (3/4 hp) or greater.
<br /> 3) Any wastewater or other substance having a pH lower
<br /> than five point five (5.5) or higher than nine point
<br /> five (9.5) or any other corrosive property capable of
<br /> causing damage or hazard to the structures,
<br /> equipment, and/or personnel at the POTW.
<br /> NOTE: Excursions outside the above established limits
<br /> may be acceptable as follows :
<br /> Maximum Excursion Duration
<br /> .5 pH unit not to exceed 60
<br /> minutes
<br /> 1.0 pH unit not to exceed 30
<br /> minutes
<br /> 1.5 pH units not to exceed 10
<br /> minutes
<br /> such excursions shall be at the discretion of the
<br /> Supervisor; however, in no case shall five or more
<br /> excursions of any type occur within a five day period
<br /> or shall the excursions in any five day period

<br /> wastewater for that period.
<br /> 4) Any wastewater or other substance containing toxic
<br /> pollutants in any sufficient quantity, either singly or
<br /> by interaction with other pollutants, to injure or
