Terms and conditions as may be required and imposed by the Department
of Public Works or its duly authorized agent in the issuance of the
permit are as follows:
A. A limitation upon the volume of sewage and the rate of flow permitted
from the premises;
B. The installation and maintenance by the permittee, at his own expense,
of facilities or equipment for intermittent or continuous measurement
of sewage, industrial wastewater or other wastes discharged from the
premises into a public sewer and maintenance of appropriate records
of all measurements;
C. The installation and maintenance by the permittee, at his own expense,
of detention tanks or other facilities or equipment for reducing the
maximum rates of discharge of sewage to such a percentage of the twenty-four-hour
rate as may be required by the Department of Public Works or its duly
authorized agent;
D. The installation and maintenance by the permittee, at his own expense,
of such pretreatment facilities as may be required by the Department
of Public Works or its duly authorized agent;
E. The installation and maintenance by the permittee, at his own expense,
of a suitable control or sampling manhole or manholes in any sewer
discharging to a public sewer for which a permit is issued;
F. The installation and maintenance by the permittee, at his own expense,
of grease, oil and sand interceptors, separators or traps that are
necessary for the proper handling of liquid wastes containing such
substances in excessive quantities or any flammable waste or other
harmful ingredients;
G. The submission to and approval by the Department of Public Works
or its duly authorized agent of the plans for any of the facilities
or equipment required to be installed and maintained by the permittee;
H. Such other terms and conditions as may be necessary to protect the
sewerage system and the public sewer tributary to it and to carry
out the intent and provisions of these rules and regulations;
I. Such terms and conditions may also provide that subsequent to the
commencement of operation of any pretreatment facilities, periodic
reports with certified test results shall be made by the permittee
to the Department of Public Works or its duly authorized agent, setting
forth adequate data upon which the acceptability of the sewage, industrial
wastewater or other wastes, after treatment, may be determined;
J. Where pretreatment of flow-equalizing facilities are provided for
any water or wastes, they shall be maintained continuously in satisfactory
and effective operation by the permittee at his expense;
K. A violation by the permittee of the permit shall be a cause for revocation
or suspension of the permit.
Whenever sewage, industrial wastewater or other wastes having characteristics other than prescribed for normal sewage as defined in §
231-1 herein, or falling within the categories of waste prohibited or restricted from public sewers pursuant to these rules and regulations, is discharged into public sewers from any premises, the Department of Public Works or its duly authorized agent shall have the right to take samples and tests as may be necessary to determine the nature and concentration of such wastes, and shall have the right to reassess its determinations by taking samples and test at any time or by periodic rechecks without notice to the person discharging such wastes.
A. Samples shall be taken and flow measurements made normally at the
control manhole or manholes.
B. In the event that the requirement for a control manhole or manholes
has been specifically waived, the samples shall be taken at a point
or points to be selected by the Department of Public Works or its
duly authorized agent.
C. When required by the Department of Public Works or its duly authorized
agent, the owner of any property served by a building sewer carrying
industrial wastewater and classified as a significant industrial user
shall install a suitable control manhole, together with such meters
and other appurtenances in the building sewers as are necessary, to
facilitate observation, sampling and measurement of the wastes. Such
manholes, when required, shall be accessibly and safely located, and
shall be constructed in accordance with plans approved by the Department
of Public Works or its duly authorized agent. The manhole 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.
D. Measurement and analyses of wastes. All measurements, tests and analyses
of the characteristics of water and wastes to which reference is made
in these rules and regulations shall be determined in accordance with
the latest edition of "Standard Methods for Examination of Water and
Waste Water," published by the American Public Health Association,
and shall be determined at the sampling part, or upon suitable samples
taken at said sampling part. Sampling shall be carried out by customarily
accepted methods to reflect the effect of constituents upon the sewage
works and to determine the existence of hazards to life, limb and
property.
In compliance with Public Laws 84-660 and 92-500 of the Water
Pollution Control Acts and amendments thereto, these regulations adopt
and use as a guide the national pretreatment standards and the Environmental
Protection Agency's (EPA) pretreatment guidelines. The Department
of Public Works recognizes that, in some cases, these pretreatment
standards may not be sufficient to protect the operation of the County
Sewer District's POTW treatment plant and enable it to comply with
the terms of the County Sewer District's SPDES permit. In such cases,
the Department of Public Works and County Sewer District reserve the
right to impose more stringent pretreatment standards than those specified
in the EPA regulations.
