No person shall discharge or cause to be discharged
the following described substances, materials, waters or wastes unless
it appears unlikely, in the opinion of the Director, that such wastes
will harm either the sewers, wastewater treatment process or equipment
or have adverse affect on the receiving stream and the Director provides
his written consent to the person making the discharge. In forming
his opinion as to the acceptability of these wastes, the Director
will give consideration to such factors as the quantities of subject
wastes in relation to flows and velocities in the sewers, materials
of construction of the sewers, the wastewater treatment processes
employed, capacity of the wastewater treatment plant, degree of treatability
of wastes in the wastewater treatment plant and other pertinent factors.
The Director may set limitations lower than the limitations established
below if, in his opinion, such more severe limitations are necessary
to meet the above obligations. The substances that require the approval
of the Director prior to discharge into the sewer system are:
A.
Wastewater having a temperature higher than 150°
F. [65° C.)].
B.
Any water or waste containing fats, grease or oils
of petroleum origin, whether emulsified or not, in excess of 100 milligrams
per liter or containing substances which may solidify or become viscous
at temperatures between 40° F. and 150° F. [4° and 65°
C.)].
C.
Any garbage that has not been properly ground. The
installation and operation of any garbage grinder equipped with a
motor of 3/4 horsepower [0.76 horsepower metric] or greater shall

such quantities that any of the above materials received in the composite
wastewater at the wastewater treatment works exceeds the limits established
in Appendix A of this Chapter or by the Director for such material.
[1]
Editor's Note: Appendix A is included at the end of this chapter.
F.
Any waters or wastes containing phenols or other wastes
or odor-producing substances in such concentrations exceeding limits
which may be established by the Director as necessary after treatment
of the composite wastewater to meet the requirements of the state,
federal or other regulatory agencies or jurisdiction for such discharge
to the receiving waters.
G.
Materials which exert, cause or contain:
(1)
Unusual concentrations of inert suspended solids,
such as but not limited to fuller's earth, lime slurries and lime
residues, or of dissolved solids, such as but not limited to sodium
chloride and sodium sulfate.
(2)
Excessive discoloration, such as but not limited to
dye wastes, vegetable tanning solutions and commercial inks.
(3)
BOD, chemical oxygen demand, nitrogen or chlorine
requirements in such quantities as to constitute a significant load
on the water pollution control plant.
(4)
Unusual volume of flow or concentration of wastes
constituting slugs as defined herein.
H.
Waters or wastes containing substances which are not
amenable to treatment or reduction by the wastewater process employed
or are amenable to treatment only to such degree that the wastewater
treatment agencies having jurisdiction over discharge to the receiving
waters or which would cause the wastewater treatment plant sludge
to become unsuitable for disposal.
I.
Any water or wastes which, by interaction with other
water or wastes in the public sewer system, release obnoxious gasses,
form suspended solids which interfere with the collection system,
or create a condition deleterious to structures and treatment processes.
J.
Pollutants in excess of the allowed limits as determined
by the National Pretreatment Standards developed by the EPA, 40 CFR
403, including all amendments.
If any waters or wastes are discharged or are
proposed to be discharged to the public sanitary sewers which waters
contain the substances or possesses the characteristics enumerated
above and which, in the judgement of the Director, may have a deleterious
effect upon the wastewater facilities, processes, equipment or receiving
waters or which otherwise create a hazard to life or constitute a
public nuisance, the Director may:
A.
Reject the wastes.
B.
Require pretreatment to an acceptable condition for
discharge to the public sewers.
C.
Require control over the quantities and rates of discharges.
D.
Require payment to cover the added cost of handling
and treating the wastes not covered by existing taxes or sewer charges.
If the Director permits the pretreatment or equalization of waste
flows, the design and installation of the plants and equipment shall
be subject to the review and approval of the Director.
E.
Require any user discharging wastes that release or
generate obnoxious gases to provide and install equipment for eliminating
odors wherever they might be generated by such wastes in the wastewater
facilities or POTWs.
Grease, oil and sand interceptors shall be provided
when, in the opinion of the Director, they are necessary for the proper
handling of liquid wastes containing floatable grease in excessive
amounts or any flammable wastes, sand or other harmful ingredients,
except that such interceptors shall not be required for private living
quarters or dwelling units. All interceptors shall be of a type and
capacity approved by the Director and shall be located as to be readily
and easily accessible for cleaning and inspection. In the maintaining
of these interceptors, the owner shall be responsible for the proper
removal and disposal by appropriate means of captured material and
shall maintain records of the dates and means of disposal which are
subject to review by the Director. Any removal and hauling of the
collected materials must be performed by approved waste firms or individuals.
Where pretreatment or flow-equalizing facilities
are provided or required for any waters or wastes, they shall be maintained
continuously in satisfactory and effective operation by the owner
at his expense.
Unless otherwise authorized by the Director,
all persons discharging industrial wastes into a public sewer shall
install a suitable structure, together with such necessary meters
and other appurtenances in the building sewer to facilitate observation,
sampling and measurement of wastes. Such structure, when required,
shall be accessibly and safely located and shall be constructed in
accordance with the plans approved by the Director. The structure
shall be installed by the owner at his expense and shall be maintained
by him so as to be safe and accessible at all times. If measuring
devices are to be permanently installed, they shall be of a type approved
by the Director. A detailed drawing shall be provided to the Director
for his records showing the locations of all such structures.
A.
The Director may require a user of sewer services
to provide information needed to determine compliance with this chapter.
These requirements may include:
(1)
Wastewater discharge peak rate and volume over a specified
time period.
(2)
Chemical analyses of wastewaters.
(3)
Information on raw materials, processes and products
affecting wastewater volume and quality.
(4)
Quality and disposition of septic liquids, sludge,
oil, solvent or other materials important to sewer use control.
(5)
A plot plan of sewers of the user's property showing
sewer and pretreatment facility location.
(6)
Details of wastewater pretreatment facilities.
(7)
Details of systems to prevent and control the losses
of materials through spills to the municipal sewer.
B.
All measurements, tests and analyses of the characteristics
of waters and wastes to which reference is made in this chapter shall
be determined in accordance with the latest edition of Standard Methods
or EPA Guidelines Establishing Procedures for the Analysis of Pollutants.
Sampling methods, location, times, durations and frequencies are to
be determined on an individual basis subject to approval by the Director.
High-strength industrial waste surcharges will be determined during
the billing period after due allowance for values not believed to
be representative. Any person may request the Director to make new
tests, such tests to be at the expense of the person discharging the
waste and such tests to be of a minimum of 24 hours' duration unless
approved. If the Director is satisfied that such test was made when
the plant was operating under normal conditions, the results of these
tests shall be used in computing the subsequent industrial waste surcharges.
No statement contained in this Article shall
be construed as preventing any special agreement, in writing, between
the Director and any industrial concern whereby an industrial waste
of unusual strength or character may be accepted by the Director for
treatment, provided that the treatment plant can accept the waste
and it will not cause the plant to contravene its permit limits.
