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.
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.
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.
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.
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.)
