[R.O. 2009 §13.16.170]
A.
Any pollutant
introduced to a publicly owned treatment works facility by a non-domestic
source, which would create an atmosphere causing the POTW to violate
its NPDES permit, or not meet applicable pretreatment standards, shall
not pass through the POTW or interfere with the operation or performance
of the works. The following materials, substances and wastes shall
not be discharged into the City sewers:
1.
Any
water or waste containing fats, wax, grease or oils, whether emulsified
or not, in excess of one hundred (100) ppm or containing substances
which may solidify or become viscous at temperatures between thirty-two
degrees Fahrenheit (32°F) and one hundred fifty degrees Fahrenheit
(150°F).
2.
Any
garbage that has not been properly shredded. The installation and
operation of any garbage grinder equipped with a motor of three-fourths
(¾) horsepower or greater shall be the subject to the review
and approval of the Director of Utilities.
3.
Any
pollutants which create a fire or explosion hazard in the POTW including,
but not limited to, waste streams with a closed cup flashpoint of
less than one hundred forty degrees Fahrenheit (140°F) or sixty
degrees Celsius (60°C) using the test methods specified in 40
CFR 261.21. Any gasoline, benzene, naphtha, diesel fuel, fuel oil
or other flammable or explosive liquid, solid or gas which creates
an atmosphere within the wastewater system that exceeds the following
limits: At no time shall two (2) successive readings on an explosion
hazard meter, at the point of discharge into the system (or at any
point in the system) be more than five percent (5%) nor any single
reading over ten percent (10%) of the lower explosive limit (LEL)
of the meter.
4.
Any
waters or wastes containing strong acid, iron pickling wastes or concentrated
plating solutions whether neutralized or not.
5.
Petroleum
oil, non-biodegradable cutting oil or products of mineral oil origin
in amounts that will cause interference or pass through. Any solid
or viscous material in quantities capable of causing obstruction to
the flow in sewers or interference with the proper operation of any
portion of the wastewater system such as, but not limited to, the
following substances: ashes, wax, paraffin, cinders, sand, bones,
mud, straw, shavings, scrap metal, glass, rags, lint, feathers, tar,
plastics, wood, sawdust, paunch manure, hair and flesh, entrails,

7.
Pollutants
which result in the presence of toxic gases, vapors or fumes within
the POTW in a quantity that may cause acute worker health and safety
problems. Any noxious or malodorous gas or other substance, such as
detergent foam, which either singly or by interaction with other wastes
is capable of creating a public-nuisance or hazard to life or of preventing
safe entry into sewers for purposes of inspection, maintenance or
repair.
8.
Any
concentrated dye wastes or other wastes which are either highly colored
or could become highly colored by reacting with other wastes.
9.
Any
material or substance not specifically mentioned in this Section which,
in itself or by interaction with other wastes, becomes corrosive,
toxic or noxious, irritating to humans and animals or adversely affects
any treatment process, sewage works or the receiving watercourse.
[R.O. 2009 §13.16.180]
A.
No person
shall discharge or cause to be discharged into any City sewer any
of the following substances in excess of stated quantities or concentrations
without first having obtained prior approval from the Director of
Utilities:
1.
Any
liquid or vapor having a temperature in excess of one hundred fifty
degrees Fahrenheit (150°F) upon entry into the sewerage system
or in excess of one hundred four degrees Fahrenheit (104°F) upon
entering the wastewater treatment plant.
2.
Wastes
having a pH less than six (6.0) or greater than nine and one-half
(9.5) or otherwise having chemical properties which are hazardous
or capable of causing damage to the sewage works or personnel.
3.
Any
waters of wastes containing toxic or poisonous solids, liquids or
gases in sufficient quantity, either singly or by interaction with
other waste, to injure or interfere with any sewage treatment process,
constitute a hazard to humans or animals, create a public nuisance
or create any hazard in the receiving waters of the sewage treatment
plant. The industries for which the Environmental Protection Agency
has published regulations establishing categorical pretreatment standards
shall be subject to those standards, unless more stringent local limits
exist whereby the industry shall be subject to the stricter of the
two (2) standards. Industries or pollutants for which there are no
existing categorical standards shall be subject to the following local
limits:

4.
Any
radioactive wastes or isotopes of such half-life or concentration
which may exceed limits established by the Director of Utilities or
latest State and Federal regulations.
5.
Any wastes which are of unusual volume, concentration of solids or composition, as for example in total suspended solids of inert nature (such as Fuller's earth) and/or in total dissolved solids (such as sodium chloride, calcium chloride or sodium sulfate) or which have a BOD which exceeds the standards of normal sewage (as defined in Article I).
B.
Limits
established in this Section may be modified and the volume and concentration
of contributions from users may be subject to more stringent requirements
by the Director so that the aggregate contributions within the City's
treatment plant do not cause treatment difficulties or produce a wastewater
of treatment facility effluent, air emission or sludge discharge in
violation of the limits and requirements of applicable Federal and
State regulations, NPDES permits or applicable pretreatment standards.
C.
In any
instance in which Federal and/or State requirements or limitations
are more stringent than the limitations set forth in this Article,
said requirements and limitations on discharges shall be met by all
users subject to such requirements or limitations.
[R.O. 2009 §13.16.190]
A.
If any wastewater containing any of the substances or possessing any of the characteristics enumerated in Article IV of this Chapter or which, in the judgment of the Director, may interfere with the wastewater system or have a harmful effect on receiving waters or would cause the POTW to violate its NPDES permit, does not meet applicable pretreatment standards and is discharged or is proposed to be discharged into the wastewater system, the Director may:
1.
Refuse
to allow discharge of the waste into the City's wastewater system;
2.
Require
pretreatment to a condition acceptable for discharge into the wastewater
system;
3.
Require
control over the quantities and rates of discharge;
4.
Require
payment to cover added cost of handling and treating the wastes not
covered by existing taxes or sewer charges;
5.
Require
the development of compliance schedules for meeting any applicable
pretreatment standards;
7.
Carry
out all inspections, surveillance and monitoring necessary to determine
compliance with any applicable pretreatment standards;
8.
Obtain remedies for non-compliance by any user. Such remedies may include injunctive relief, the civil penalties specified in Article VII of this Chapter or appropriate criminal penalties; and/or
9.
Terminate
service.
B.
When
considering the above alternatives, the Director shall ensure that
the City is in compliance with all Federal and State requirements
or limitations. The Director shall also take into consideration the
cost-effectiveness, economic impact of each alternative on the user
and the City and any other factors relevant to the situation. If the
Director permits the pretreatment or equalization of waste flows,
the design and installation of the facilities and equipment shall
be subject to review and approval by the Director. The Director shall
either approve or reject the pretreatment design within ninety (90)
days after its submittal.
[R.O. 2009 §13.16.200]
No user shall increase the use of potable or process water in
any way for the purpose of diluting a discharge as partial or complete
substitute for pretreatment required to comply with the provisions
of this Article.
[R.O. 2009 §13.16.210]
Each user shall provide safeguards against the accidental discharge into the wastewater system of prohibited or restricted substances. Facilities to prevent accidental discharge to the wastewater system of prohibited or restricted substances shall be provided and maintained at the user's expense. In the case of any accidental spill, it shall be the responsibility of the user to report all such accidents to the Director in accordance with the requirements set forth in Article VI, Section 715.290 of this Chapter. Expenses incurred by the City during the abatement of spill events may be charged to the responsible person.
[R.O. 2009 §13.16.220]
At the discretion of the Director, the POTW may accept the discharge
at the treatment works from private domestic waste haulers. This discharge
point shall be the manhole at the headworks of the plant just ahead
of the comminutor at the City's wastewater treatment facility on South
Ingram Road, Sikeston, Missouri. The hauler shall, annually, register
all vehicles with the Director and with each load the hauler shall
sign a form indicating the name(s) and address(es) of points of origin
of the waste. The POTW operator shall retain a sample of each load
for testing at the discretion of the Director. All private waste haulers
shall pay a minimum fee of five dollars ($5.00) per load.
