If any waters or wastes are discharged or are proposed to be discharged into the public sewers which are objectionable wastes, as defined in § 208-8, or which, in the judgment of the Commissioner, may have a deleterious effect upon the sewage treatment works processes, equipment or receiving waters or which otherwise create a hazard to life or constitute a public nuisance, the Commissioner may:
Grease, oil, hair and sand interceptors shall
be provided when the Commissioner determines that they are necessary
for the proper handling of liquid wastes containing grease in excessive
amounts or any flammable wastes, sand or other harmful ingredients;
except that such interceptors shall not be required for private dwellings.
All the interceptors shall be located as to be readily and easily
accessible for cleaning and inspection. No dishwasher discharge will
be allowed to pass through any of the aforementioned interceptors.
Where preliminary treatment, including interceptors and traps or flow-equalizing
facilities, are provided for any waters or wastes, they shall be maintained
continuously satisfactory and in effective operation by the owner
at his or her expense. There shall be no bypass of the pretreatment
facilities which would allow the entry of untreated or partially treated
wastes to the public sewer.
[Added 6-12-2000 by L.L. No. 4-2000]
All food preparation establishments and facilities,
including but not limited to restaurants, delicatessens, fast-food
and take-out establishments and institutional kitchens, shall install
on their premises and use automatic grease recovery systems of a description,
type and size as approved by the Building Department, in accordance
with the following:
A.
All such new establishments, new operators of existing
food preparation establishments and those existing establishments
located within the Village that move to a new location within the
Village shall be in compliance with this section no later than the
commencement of operation.
B.
All such establishments in existence and operation
prior to the enactment of this section, which undergo renovations
or which make repairs and/or install replacements affecting existing
grease recovery devices, plumbing lines and/or plumbing fixtures,
shall be in compliance with this section no later than the date of
completion of said renovations, repairs and/or installation of replacements,
or two years from the date of the enactment hereof, whichever is earlier.
C.
All such establishments in existence and operation
prior to the enactment of this section shall be in compliance therewith
no later than two years after the enactment date hereof.
When required by the Commissioner, the owner
of any property serviced by a house connection carrying industrial
wastes shall install a suitable control manhole, together with such
necessary meters and other appurtenances, including but not limited
to Parshall flumes, venturi meters and weirs, in the building sewer
to facilitate observation, sampling and measurement of the wastes.
Such manhole, when required, shall be constructed in accordance with
plans approved by the Commissioner. The manhole shall be installed
by the owner at his or her expense and shall be maintained by him
or her so as to be safe and accessible at all times. When required
by the Commissioner, discharges shall install and maintain in proper
order automatic flow proportional sampling equipment and/or automatic
analysis and recording equipment. Sampling and flow measurement facilities
shall be such as to provide safe access to authorized personnel. The
industrial wastewater discharger shall identify the effluent sampling
point used for each discharge pipe by providing a sketch or flow diagram,
as appropriate, showing the location.
All measurements, tests and analyses of the
characteristics of waters and wastes to which reference is made in
the law shall be determined in accordance with the latest edition
of Standard Methods for the Examination of Water and Wastewater and
shall be determined at the control manhole. In the event that no special
manhole has been required, the control manhole shall be considered
to be the nearest downstream manhole in the public sewer to the point
at which the building sewer is connected. Sampling shall be carried
out by customarily accepted methods and to reflect the effect of constituents
upon the sewage treatment works and to determine the existence of
hazards to life, limb and property. Sampling shall be representative
of the volume and quality of wastewater effluent discharged over the
sampling and reporting period. (The particular analyses involved will
determine whether a twenty-four-hour composite of all outfalls of
a premise is appropriate or whether a grab sample or samples should
be taken. Normally, but not always, BOD and suspended solids analyses
are obtained from twenty-four-hour composite of all outfalls, whereas
pH is determined from periodic grab samples). All sampling, analyses
and flow measurement procedures, equipment and results shall be subject
at any time to inspection by the Commissioner. Adequate care shall
be maintained in obtaining, recording and reporting the required data
on wastewater effluent quality and quantity, so that the precision
and accuracy of the data will be equal or better than that achieved
by the prescribed standard analytical procedures. The industrial wastewater
discharger shall calibrate and perform maintenance procedures on all
monitoring and analytical instrumentation at sufficiently frequent
intervals to ensure accuracy of measurements. Care shall be exercised
when collecting a composite sample to assure that the proper preservative
is present in the sample container during sample collection. Depending
on the analysis to be conducted, several different containers and
preservation techniques may be required. Samples shall be analyzed
as quickly as possible after collection. The industrial wastewater
discharger shall ascertain that the methodology used is reliable for
his or her specific wastes in his or her laboratory. Such discharger
must be able to demonstrate to the Commissioner that he or she has
a viable quality-control program.
Those industrial wastewater discharges required
to make periodic measurements of their wastewater flow and its constituents
shall annually make the minimum number of such measurements required.
Composite samples of the industrial wastewater shall be obtained for
the required analyses. Dischargers required to sample on only a few
days per year shall sample during the period of highest wastewater
flow and wastewater constituent discharge. Samples should be taken
during normal operating conditions.
The industrial wastewater discharger shall maintain
and record the results of all required analyses and measurements and
shall record, for all samples, the date and time of sampling, the
sample method used, the dates analyses were performed, who performed
the sampling and analyses and the results of such analyses. All records
shall retained for a minimum of three years, such a period to be extended
during the course of an unresolved litigation or when so requested
by the Commissioner. The industrial wastewater discharger also shall
retain all original strip-chart recordings from any continous monitoring
instrumentation and any calibration and maintenance records for a
minimum of three years, such period to be extended during the course
of any unresolved litigation or when so requested by the Commissioner.
The industrial wastewater discharger shall provide the above records
and shall demonstrate the adequacy of the flow measuring and sampling
methods upon the request of the Commissioner.
No statement contained in this article shall
be construed as preventing any special agreement or arrangement between
the Village and any industrial concern whereby an industrial waste
of unusual strength or character may be accepted by the Village for
treatment, subject to payment therefor, by the industrial concern.
No special agreements shall circumvent Federal Categroical Pretreatment
Standards.
