approval thereof first shall have been obtained from any governmental
regulatory body having jurisdiction.
(3)
Whenever facilities for preliminary treatment and handling of industrial
wastes shall have been provided by the owner of such improved property,

inspection and testing.
[Amended 9-19-1977 by Ord. No. 1977-3]

to persons or the sewer system or the sewage treatment plant.
(4)
Any noxious or malodorous gas or substance which, either singly or
by interaction with other wastes, shall be capable of creating a public
nuisance or hazard to life or of preventing entry into any sewer or

(6)
Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags,
bones, feathers, tar, plastic, wood, paunch manure, butcher's

(7)
Any water or waste having a pH lower than 9.0 or having any corrosive
property capable of causing damage or hazard to structures or equipment
of the sewer system or the sewage treatment plant or to personnel
engaged in operation and maintenance thereof.
(8)
Any water or waste containing any toxic substance in quantity sufficient
to constitute a hazard to humans or animals or to interfere with the
biochemical processes of the sewage treatment plant or that will pass
through the sewage treatment plant in such condition so that it will

(9)
Any water or waste containing suspended solids of such character
and quantity that unusual attention or expense shall be required to
handle such water or waste at the sewage treatment plant.
(10)
Any toxic radioactive isotopes, except by special permission
of the Borough.
(11)
Any drainage from building construction.
C.
Oil and grease interceptors.
(1)
Gas stations and garages are required to provide oil interceptors
of the types: Series GA, GX, GNC, GRC of Josam Manufacturing Company,
Michigan City, Indiana, or equivalent, in the proper location, where
the dangerous liquids are to be intercepted.
(2)
Restaurants or other commercial establishments, as directed, are
required to provide grease interceptors of the type Series J of the
Josam Manufacturing Company or equivalent.
D.
Nothing contained in this § 355-57 shall be construed as prohibiting any special agreement or arrangement between the Borough and any person whereby industrial wastes of unusual strength or character may be admitted into the sewer system by the Borough either before or after preliminary treatment.
A.
Required survey data. Any person desiring to make a connection to
the sewer system through which industrial wastes shall be discharged
into the sewer system shall file with the Borough an "Industrial Wastes
Questionnaire," to be furnished by the Borough, which shall supply
pertinent data, including estimated quantity of flow, to the Borough
with respect to industrial wastes proposed to be discharged into the
sewer system.
B.
Control manholes.
(1)
Any persons who shall discharge industrial wastes into the sewer
system, when required by the Borough, shall construct and thereafter
properly shall maintain, at his own expense, a suitable control manhole
to facilitate observation, measurement and sampling by the Borough.
(2)
Any such control manhole, when required by the Authority or Borough,
shall be constructed at an accessible, safe, suitable and satisfactory
location in accordance with plans approved by the Borough prior to
commencement of construction.
C.
Sewage sampling. Industrial wastes being discharged into the sewer
system shall be subject to periodic sampling, inspection and determination
of character and concentration. Such sampling, inspection and determination
shall be made by the Borough as frequently as may be deemed necessary.
Representative samples for a full working day shall be obtained by
taking hourly samples and compositing them in accordance with the
flow at the time of sampling. Sewage sampling facilities shall be
accessible to the Borough at all times. Due care shall be exercised
in the collection and preservation of all samples to insure preservation
thereof, in as nearly the natural state as possible, including refrigeration
of all samples which are intended for analysis by biochemical methods.
D.
Analysis.
(1)
The Borough shall be responsible for analysis of samples of industrial
wastes.
(2)
Laboratory methods used in the analysis of samples of industrial
wastes shall be those set forth in the latest edition of "Standard
Methods for the Examination of Water and Sewage" as published by the
American Public Health Association; provided, however, that alternate
methods for the analysis of industrial wastes may be used, subject
to mutual agreement between the Authority and the person discharging
such industrial wastes into the sewer system.
E.
Changes in types of wastes. Any owner of an improved property who
is discharging industrial wastes into the sewer system and who contemplates
change in the method of operation which will alter the type of industrial
wastes at the time being discharged into the sewer system shall notify
the Borough, in writing, at least 10 days prior to consummation of
such change.
No person shall cause the discharge of slugs of water or wastes.
Each person producing a discharge into the public sewer, in excess
of 20,000 gallons in any one day, shall construct and maintain at
his own expense a suitable storage and flow-control facility to insure
equalization of discharge over a twenty-four-hour period. This facility
shall have a capacity of at least 50% of the total normal volume of
a twenty-four-hour production period, and the outlet to the sewer
shall be equipped with a rate-discharge controller or other approved
device, the regulation of which shall be directed by the approving
authority.
The surcharge per person shall be determined as follows:
The excess pounds of biochemical-oxygen-demand (BOD), suspended solids and chlorine requirement will be computed by multiplying the person's sewage-flow volume in million gallons per day by the constant 8.345 and then multiplying this product by the difference between the person's concentrations of biochemical-oxygen-demand (BOD), suspended solids and chlorine requirement and the aforementioned "normal" concentration in parts per million by weight. The surcharge for each constituent will then be determined by multiplying the excess pounds of each constituent by the appropriate rate of surcharge listed in § 355-61. This product will then be multiplied by the number of days in the billing period to determine the surcharge. Concentration figures in the above calculations shall be daily averages in accordance with the provisions of Article VIII, § 355-58.
[Amended 9-19-1977 by Ord. No. 1977-3]
The rates of surcharge for each of the aforementioned constituents
shall be as follows:
The rates of surcharge shall be reviewed annually by the Borough
in order to determine whether or not they are sufficient to defray
the fixed charges, amortization costs, and annual cost of operation,
as determined from the sewage treatment plant records. If the difference
between the revenue derived from the rates of surcharge and the total
annual cost is sufficient to justify an increase in the rates, the
Borough shall make the appropriate change.
