<br />(2) Solid or viscous substances. Solid or viscous substances in
<br />amounts which will cause obstruction of the POTW resulting in
<br />interference but in no case solids greater than one half inch in
<br />any dimension. Prohibited materials include but are not limited to:
<br />grease, uncomminuted garbage, animal guts or tissues, paunch
<br />manure, bones, hair, hides or fleshings, entrails, whole blood,
<br />feathers, ashes, cinders, sand, spent lime, stone or marble dust,

<br />residues from refining or processing of fuel or lubricating oil,
<br />ground paper products, and material from grinders, residues or
<br />solids from a pretreatment facility, and similar substances.
<br />(3) Petroleum, cutting or mineral oils. Petroleum oil, non-
<br />biodegradable cutting oil, or products of mineral oil origin, in
<br />amounts that will cause interference or pass through.
<br />(9) Corrosive Wastes. Any wastewater having a pH less than 5.0 or more
<br />than 9.0 or wastewater having any other corrosive property capable
<br />of causing damage to the POTW(s) or equipment.
<br />(5) E*c~es i'~--a~'i se :a~y~~^` -^'~^° POTW interferenae.
<br />Any wastewater containing pollutants, including oxygen-demanding
<br />pollutants, (BOD, etc.) , iR strf€tetetr~~ae~-}+-, ~f' ^~,~e~
<br />,=,} released in a discharge at a flow volume, flow rate
<br />and/or pollutant concentration which, either singly or by
<br />interaction with other pollutants, to cause interference with the
<br />POTW.
<br />(6) Temperature limit. Any wastewater having a temperature greater than
<br />one hundred fifty (150) degrees Fahrenheit (sixty-six (66) degrees
<br />Celsius), or which will inhibit biological activity in the POTW
<br />treatment plant resulting in interference, but in no case
<br />wastewater. which causes the temperature at the introduction into
<br />the treatment plant to exceed one hundred four (104) degrees
<br />Fahrenheit (forty (90) degrees Celsius).
<br />(7) Toxic gases. Any pollutants which result in the presence of toxic
<br />gases, vapors or fumes within the POTW in a quantity that may cause
<br />acute worker health and safety problems.
<br />(8) Truck or hauled pollutants. Any truck or hauled pollutants, except
<br />at discharge points designated by the Executive Director in
<br />accordance with Section 2.9 of this ordinance.
<br />(9) Oile and grease. Fats, oils, or greases of animal or vegetable
<br />origin in concentrations greater than 100 mg/l.
<br />(10) Noxious materials. Any noxious or malodorous solids, liquids or
<br />gases, or .other wastewater which either singly or by interaction
<br />with other wastes are sufficient to create a public nuisance or
<br />hazard to :life or are sufficient to prevent entry into the sewers
<br />for maintenance and repair.
<br />(11) Improperly shredded garbage. Garbage that has not been ground or
<br />comminuted to such a degree that all particles will be carried
<br />freely in suspension under flow conditions normally prevailing in
<br />the public sewers, with no particle greater than one-half inch in
<br />any dimension.
<br />(12) RadioaativO wastes. Any wastewater containing any radioactive
<br />wastes or isotopes except as specifically approved by the Executive
<br />Director in compliance with applicable State and or Federal
<br />regulations.
<br />(13) Toxic subitanaea. Any wastewater discharge which alone or in
<br />combination with other wastewater causes sag the treatment
<br />plant effluent to violate State Water Quality Standards for toxic
<br />substancesas described in 15A NCAC 2B .0200.
<br />
<br />
<br />
<br />(19) Unpolluted waters. Storm water, surface water, ground water,
