,5. .,nv noxious or malodorous liquids, gases, or solids which
<br />c~ner ~n~i7 or b? interaction with other wastes are capable of
<br />cre.~t~n~ a ouslic nuisance or hazard to life or are sufficient to
<br />prev~,n5 enzr'.' into the sewers for 5heir maintenance and repair.
<br />
<br /> o. Any substance which may cause the wastewater disposal system's
<br />effluent or any other product of the wastewater treatment process such as
<br />residues, slud~es, or scums, to be unsuitable for reclamation and reuse
<br />or to interfere with the reclamation process. In no case. shall a sub-
<br />stance discharged to the wastewater disposal system cause the system
<br />to be in noncompliance with sludge use or disposal criteria, guidelines
<br />or regulations developed under Section 405 of the Act; any criteria,
<br />gui~c~n-L,' ~J r~6u~afions affecting sludge use or disposal developed
<br />pursuan~ to ~he Solid Wastes Disposal A~t, the Clean Air Act, the Toxic
<br />Substances Control Act, or State standards applicable to the sludge
<br />management method being used.
<br /> 7. .~ny substance which will cause the wastewater disposal system
<br /> :o violate i:s NPDES Permit or the receiving water quality standards.
<br /> 8. 7~ny wastewater which creates conditions at or near the waste-
<br /> water disposal system which violates any statute or any rule, regulation
<br /> or ordinance of any public agency or state or federal regulatory body.
<br /> (a) ::o person shall discharge or cause to be discharged the following
<br /> described substances, materials, waters or wastes if it appears likely
<br /> in the opinicn of the City Engineer that such wastes can harm either the
<br /> sewers, wastewater treatment process, or equipment, have an adverse effect
<br /> on ~he receivzng stream, or can otherwise endanger life, l%mb, public
<br /> proper~y, or constitu'te a nuisance. In forming his opinion as to the
<br /> acceptabili~? of the wastes, the City Engineer will give consideration
<br /> ~o such factors as the quantities of subject wastes in relation to flows
<br /> and velocities in the sewers, materials of construction of the sewers,
<br /> nature of the wastewater treatment process, capacity of the wasgewater
<br /> treatment plant~ degree of treatability of wastes in the wastewater
<br /> treatment plant, and other pertinent factors. The substances prohibited
<br />
<br />arc:
<br />
<br />~% .:.ny liquid or vapor having a temperature .higher than
<br /> one hundred fifty (150°F) (65°C), or causing, indi-
<br /> vidually or in combination with other wastewater, the
<br /> influent at the wastewa~er treatment plant to have a
<br /> temperature exceeding 104°F (40°C) -
<br />(2) ;uny ~ater or waste containing fats, wax, grease, or
<br /> oils, whether emulsified or not, in excess of twenty-
<br /> five (25) mg/1 or containing substances which may
<br /> solidify or become viscous at temperatures between
<br /> thirty-two (32°c) and one hundred fifty (150°F)
<br /> (0 and 65°C).
<br /> .~ny wa~ers or wastes containing strong acid iron
<br /> pickling wastes, or concentrated plating solutions
<br /> whether neutralized or not.
<br /> .-'.ny waters or wastes containing iron, chromium, copper,
<br /> zinc, and similar objectionable or toxic substances;
<br /> or wastes exerting an excessive chlorine requirement,
<br /> to such degree.' that any such material received in the
<br /> composite wastewater at the wastewater treatment works
<br /> exceeds reasonable limits.
<br /> (5) Any waters or wastes containing phenols or other taste-
<br /> or-odor producing substances, in such concentrations
<br /> exceeding limits after treatment of the composite
<br /> wastewater, to meet the requirements of the State,
<br /> Federal, or other public agencies of jurisdiction
<br /> for such discharge to the receiving waters.
<br /> (6) Any radioactive wastes or isotopes of such half-life
<br /> or concentration as may exceed limits in compliance
<br /> with applicable State or Federal regulations.
<br /> (7) Any waters or wastes having a pH in excess of 10.0.
<br /> (8) ?!aterials which exert or cause:
<br /> (1) Unusual concentrations of inert suspended solids
<br /> such as but not limited to, Fullers earth, lime slurries,
<br /> and lime ~esidues) or of dissolved solids (such as, but no~
<br /> limited to, sodium chloride and sodium sulfate).
<br /> (2) Excessive discoloration (such as, hut not limited to,
<br /> dye wastes and vegetable '.tanning solutions).
<br /> (~) Unusual gOD, chemical oxygen de,~and, or chlorine
<br />
