Ordinance No. 92 - 133 Page 6
<br />In the event that a storm sewer is not readily available, as
<br />determined by the City Engineer, to serve storm sewer piping for roof
<br />runoff, then such roof runoff may be discharged by underground storm
<br />sewer piping to a ditch or stream or to a leaching bed designed and
<br />constructed in accordance with standards set by the City Engineer.
<br />Splash blocks may only be used when authorized under the provisions
<br />of Section 911.19, or for small roof areas such as sheds or garages
<br />accessory to existing single family residences when approved by the
<br />City Engineer, and no water is allowed to drain onto adjacent
<br />property, accumulate in depressions, or otherwise become apublic
<br />hazard or nuisance.
<br />(c) No person shall discharge or ca.use to be discharged any of the following
<br />described waters or wastes into any public sewers:
<br />1. Any wastewater having a temperature which will inhibit biological
<br />activity in the POTW treatment plant resulting in interference; but
<br />in no case, wastewater with a temperature at the introduction into
<br />POTW which exceeds forty degrees Centigrade, 104 degrees Fahrenheit.
<br />2. Any ga.soline, benzene, na.phtha, fuel oil, or other flanunable or
<br />explosive liquids, solicls or gases which by reason of their nature or
<br />quantity are or may be sufficient, either alone or by interaction, to
<br />cause fire or explosion or be injurious in any other way to the
<br />operation of the POTW. Under no circumstances shall the flashpoint of
<br />any discharge be less than 140 degrees Fahrenheit or 60 degrees
<br />Centigrade as measured using the closed cup test method specified in
<br />40 CFR 261.21.
<br />3. Any discharge of petroleum oil, nonbiodegrada.ble cutting oil or
<br />products of mineral oil origin in amounts that can cause interference
<br />or pass through; lut in no case, water or wastes containing free
<br />oils, emulsified oils and grease exceeding an average of one hundred
<br />parts per million or 833 pounds per million ga.llons, of ether soluble
<br />matter.
<br />4. Any waters or wastes containing toxic or poisonous solids, liquids or
<br />gases in sufficient quantity, either singly or by interaction with
<br />other wastes, to injure or interfere with any sewage treatment
<br />process, constitute a hazard to humans or animals, create a public
<br />nuisance or cxeate any hazard in the receiving waters of the sewage
<br />treatment plant, including cyanides.
<br />5. Any garbage that has not been properly shredded. The installation
<br />and operation of any garbage grinder equipped with a motor of

<br />residues, cannery waste, bulk solids or any other solid or viscous
<br />substance capable of causing obstruction to the flow in sewers or
<br />other interference with proper operation of the sewage works.
<br />7. Any water or wastes containing TSS of such character and quantity
<br />that unusual attention or expense is required to handle such
<br />materials at the sewage treatment plant, or any substance which may
<br />cause the POTW's effluent or treatment residues, sludges or scums, to
<br />be unsuitable for reclamation and reuse or to interfere with the
<br />reclamation process.
