§ 162-22. Permits; when
required.
It shall be
unlawful for any person to discharge directly or indirectly into public sewers
or into any private sewer or any combined sewer discharging into a public
sewer, sewage combined with industrial wastes or other wastes, or industrial
wastes or other wastes the characteristics of which combination do not conform
to the concentration limits prescribed for normal sewage under Article II
herein, or to discharge any toxic substances or any other objectionable
material or substances as specified under Articles IV, V, VI and VII herein,
except under the issuance of a permit therefor by the County Commissioner and
Superintendent and upon such terms and conditions as may be established by the
County Commissioner or Superintendent in the issuance of such a permit.
§ 162-23. Applications
for permits.
All
applicants for a permit to discharge sewage combined with industrial wastes or
other wastes into public sewers shall fill out and file with the County
Commissioner an industrial sewer connection application as a prerequisite for
the consideration of such a permit. The following information is to be
furnished by the applicant with a duplicate copy filed with the
Superintendent:
A. Plat
of the property showing accurately all sewers, drains and house
connections.
B. Plans
and specifications covering any work proposed to be performed under the
permit.
C. A
complete schedule of all process waters and industrial wastes produced or
expected to be produced at said property or premises, including a description
of the character of each waste, the daily volume and maximum rates of discharge
and representative analyses.
D. The
name and address of the person or firm who will be responsible for the
performance of the work to be covered by the permit.
E. Such
other information as may be required by the County Commissioner or
Superintendent.
§ 162-24. Terms and
conditions.
Terms and
conditions as may be required and imposed by the County Commissioner or
Superintendent 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 wastes or other wastes discharged from the premises into a public
sewer.
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 County Commissioner or Superintendent.
D. The
installation and maintenance by the permittee, at his own expense, of such
preliminary treatment facilities as may be required by the County Commissioner
or Superintendent.
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 and carrying such sewage.
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 County Commissioner or Superintendent 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 sewer system and
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 preliminary treatment facilities, periodic reports shall be
made by the permittee to the County Commissioner and Superintendent setting
forth adequate data upon which the acceptability of the sewage, industrial
wastes or other wastes, after treatment, may be determined.
J. Where
preliminary treatment or flow-equalizing facilities are provided for any water
or wastes, they shall be maintained continuously in satisfactory and effective
operation by the permittee (or owner) at his expense.
K. A
violation by the permittee of the permit shall be a cause for revocation or
suspension of the permit.
§ 162-25. Sampling and
testing wastes.
A. Whenever
sewage, industrial wastes or other wastes having characteristics other than
prescribed for "normal sewage" as defined in Article II herein, or
containing toxic substances or other material or substances excluded from
public sewers pursuant to these rules and regulations is discharged into public
sewers from any premises, the County Commissioner or Superintendent 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 his
determinations by taking samples and tests at any time or by periodic rechecks
without notice to the person discharging such wastes.
B. Samples
shall be taken and flow measurements made whenever possible at the control
manhole or manholes.
C. In
the event that a control manhole or manholes have not been required, the
samples shall be taken at a point or points to be selected by the County
Commissioner or Superintendent.
§ 162-26. Control
manholes.
When
required by the County Commissioner or Superintendent, the owner of any
property serviced by a building sewer carrying industrial wastes shall install
a suitable control manhole together with such necessary meters and other
appurtenances in the building sewer to facilitate observation, sampling, and
measurement of the wastes. Such manhole, when required, shall be accessibly and
safely located, and shall be constructed in accordance with plans approved by
the County Commissioner and Superintendent. 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.
§ 162-27. Measurement
and analyses of wastes.
All
measurements, tests, and analyses of the characteristics of waters and wastes
to which reference is made in these rules, regulations and ordinances shall be
determined in accordance with "Standard Methods for the Examination of
Water and Waste Water," published by the American Public Health
Association, and shall be determined at the control manhole provided, or upon
suitable samples taken at said control manhole. In the event that no special
manhole has been required, the control manhole shall be considered to be the
nearest suitable one downstream in the public sewer to the point at which the
building sewer is connected. 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. (The
particular analyses involved will determine whether a twenty-four-hour
composite of all discharges of a premise is appropriate or whether a grab sample
or sample should be taken. Normally, but not always, BOD and suspended solids
analyses are obtained from twenty-four-hour composites of all discharges where
pH's are determined from periodic grab samples.)
