A.
The discharge of excessive amounts of unpolluted water or waste to
the public sanitary sewerage system is expressly prohibited. However,
such discharges to combined sewers or storm sewers will be permitted
wherever such sewers have adequate capacity. The Borough reserves
the right to define the amount it deems excessive in each particular
situation.
B.
The discharge of any garbage to the public sanitary sewerage system
is expressly prohibited unless the garbage has first been properly
shredded by a garbage grinder or garbage disposal device.
C.
No person or user shall contribute or cause to be contributed, directly
or indirectly, any pollutants that will pass through the POTW or interfere
with the operation or performance of the POTW. These general prohibitions
apply to all such users of the POTW, whether or not the user is subject
to federal categorical pretreatment standards or any other federal,
state or local pretreatment standards or requirements. A user may
not discharge any sanitary sewage or industrial wastes which will
contribute the following substances to the POTW:
(1)
Any liquids, solids or gases which by reason of their nature or quantity
are or may be sufficient, either alone or by interaction with any
other substances, to create a fire or explosion hazard in the POTW,
including, but not necessarily limited to, any waste streams with
a closed-cup flashpoint of less than 140° F. or 60° C., using
the test methods specified in 40 CFR 261.21. At no time shall two
successive readings on an explosion hazard meter at the point of discharge
into the public sewer system (or at any point in the system) be more
than 5%, nor any single reading over 10% of the lower explosive limit
(LEL) of the meter. Restricted materials include, but are not limited
to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers,
alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates,
bromates, carbides, hydrides and sulfides and any other substances
which the Borough, the DEP or the EPA deems to pose a fire or explosion
hazard.
(2)
Any solid or viscous substances which may cause obstruction to the
flow in a sewer, cause mechanical action which will destroy the sewer
structures or in the opinion of the Borough may cause other interference
with the operation of the POTW, including but not limited to grease,
wax, garbage with particles greater than 1/2 inch in any dimension,
animal guts or tissues, paunch manure, bones, hair, hides or fleshings,
entrails, whole blood, feathers, construction materials or debris,
ashes, cinders, sand, spent lime, stone or marble dust, metal, glass,
straw, shavings, grass clippings, rags, spent grains, spent hops,
wastepaper, wood, plastics, gas, tar, asphalt residues, residues from
refining or processing of fuel or lubricating oil, mud or glass grinding
or polishing wastes.
(3)
Any wastewater containing toxic pollutants in sufficient quantity,
either singly or by interaction with other pollutants, to injure or
interfere with any wastewater treatment process, constitute a hazard
to humans or animals, create a toxic effect in the receiving waters
of the POTW or exceed the limitation set forth in a categorical pretreatment
standard. A toxic pollutant shall include but not be limited to any
pollutant identified pursuant to Section 307(a) of the Act.
(4)
Any noxious or malodorous liquid, gas or solid which, either singly
or by interaction with other wastes, is, in the opinion of the Borough,
sufficient to create a public nuisance or hazard to life or is sufficient
to prevent entry into the sewers for their maintenance and repair.
(5)
Any substance which may cause the POTW's effluent or any other
product of the POTW, such as residues, sludges or scums, to be unsuitable
for reclamation and reuse or to interfere with the reclamation process
where the POTW is pursuing a reuse and reclamation program. In no
case shall a substance discharged to the POTW cause the POTW to be
in noncompliance with sludge use or disposal criteria, guidelines
or regulations developed under Section 405 of the Act, any criteria,
guidelines or regulations affecting sludge use or disposal developed
pursuant to the Solid Waste Disposal Act, the Clean Air Act, the Toxic
Substances Control Act or state criteria applicable to the sludge
management method being used.
(6)
Any substance which will cause the POTW to violate its NPDES and/or
state disposal system permit or the receiving water quality standards
for the Allegheny River.
(7)
Any wastewater containing dyes, paints, pigments, ink or other coloring
agents which are not removed by the treatment process and which, in
the opinion of the Borough, will result in a discoloration or other
undesirable physical change in the appearance of the receiving stream.
(8)
Any wastewater having a temperature in excess of 65° C. (150°
F.) or which will inhibit biological activity in the POTW treatment
plant resulting in interference, but in no case wastewater that causes
the temperature of the wastewater at the point of introduction into
the POTW treatment plant to exceed 40° C. (104° F.).
(9)
Any pollutant, including oxygen-demanding pollutants (BOD, etc.)
released in a discharge at a flow rate and/or pollutant concentration
which will cause interference to the POTW. Where the Borough deems
it advisable, it may require any person discharging industrial wastes
to utilize flow equalization or restricted discharge rates to prevent
potential slug loading problems, such as in the case of batch discharges.
(10)
Any wastewater containing any radioactive wastes or isotopes
of such half-life or concentration as may exceed limits established
by the Borough in compliance with applicable state or federal regulations.
(11)
Any liquids or wastes containing suspended solids of such quality
and/or quantity that there is interference with the POTW operation
or that become burdensome to the operation and maintenance of the
wastewater treatment plant facilities.
(12)
Any wastewater having a pH lower than 5.5 or higher than 9.5
or having any other corrosive property which may cause damage or hazard
to structures, equipment or personnel of the POTW. Where the Borough
deems it advisable, it may require any person discharging industrial
wastes to install and maintain, at his own expense, in a manner approved
by the Borough, a suitable device to continuously measure and record
the pH of the wastes so discharged.
(13)
Any wastewater containing petroleum oil, nonbiodegradable cutting
oil or products of mineral oil origin in amounts that will cause interference
or pass-through or wastewater containing more than 100 mg/l of fat,
oil or grease (hexane extractable) of animal or vegetable origin.
(14)
Any wastewater containing insoluble, nonflocculent substances
having a specific gravity in excess of 2.65 or soluble substances
in such concentration as to cause the specific gravity of the waste
to be greater than 1.1.
(15)
Any wastewater or pollutants which result in the presence of
toxic gases, vapors or fumes within the POTW in a quantity that may
cause acute or chronic worker health and safety problems.
(16)
Any wastewater containing more than 10.0 parts per million of
any of the following gases: hydrogen sulfide, sulfur dioxide, nitrous
oxide or any of the halogens.
(17)
Any trucked or hauled wastewater or pollutants, except at a
discharge point(s) designated by the Borough.
D.
When the Borough determines that a user is contributing any of the above-enumerated substances to the POTW in such amounts that will pass through or interfere with the operation of the POTW, the Borough shall advise the user of the impact of the contribution on the POTW; develop specific effluent limitation(s) for such user to correct the interference with the POTW; and/or initiate appropriate enforcement action against the user pursuant to the provisions of Article X of this chapter.
A.
No person shall discharge any wastewaters containing any of the following
substances in solution in concentrations exceeding the following maximum
permissible concentrations:

B.
The limits set forth above may be amended from time to time as deemed
necessary by the Borough to protect the facilities and ensure the
POTW's compliance with applicable NPDES permit conditions and
water quality standards.
No statement contained in this chapter shall be construed as
prohibiting any special agreement or arrangement between the Borough
and any person or industrial user whereby an industrial waste of unusual
strength or character may be discharged to the POTW by the user, provided
the objectives of the general pretreatment regulations and the provisions
of this chapter are fulfilled. Similar to any other requirements imposed
under this chapter, the provisions of any such special agreement will
be superseded by any more stringent requirements of any applicable
federal categorical pretreatment standard.
Upon the promulgation of the federal categorical pretreatment
standard for a particular industrial subcategory, the federal standard,
if more stringent than limitations imposed by the Borough under this
chapter for sources in that subcategory, shall immediately supersede
the limitations imposed by the Borough under this chapter. The Borough
shall notify all affected users of the applicable federal standards
and the applicable reporting requirements under 40 CFR 403.12, such
as the baseline monitoring report.
A.
Where the Borough's wastewater treatment system achieves consistent
removal of pollutants limited by federal pretreatment standards, the
Borough may apply to the approval authority for modification of specific
limits in the federal pretreatment standards. "Removal" shall mean
a reduction in the amount of a pollutant or an alteration of the nature
of a pollutant in the influent to the POTW to a less toxic or harmless
state in the effluent.
B.
Consistent removal shall mean the average of the lowest 50% of the
removals measured according to the procedures set forth in Section
403.7(b)(2) of Title 40 of the Code of Federal Regulations, Part 403,
General Pretreatment Regulations for Existing and New Sources of Pollution,
promulgated pursuant to the Act. The Borough may modify pollutant
discharge limits in the federal pretreatment standards if the requirements
contained in 40 CFR 403.7 are fulfilled and prior approval from the
approval authority is obtained.
State requirements and limitations on discharges shall apply
in any case where they are more stringent than federal requirements
and limitations or those imposed by the Borough under this chapter.
The Borough reserves the right to establish by supplemental
ordinances more stringent limitations or requirements on discharges
to the POTW if deemed necessary.
No user shall ever increase the use of process water or cooling
water or in any way attempt to dilute a discharge as a partial or
complete substitute for adequate treatment to achieve compliance with
the limitations contained in the federal categorical pretreatment
standards or in any other specific pollutant limitation developed
by the Borough or state. The Borough may impose mass limitations on
industrial users who are using dilution to meet federal categorical
pretreatment standards or any other specific pollutant limitation
developed by the Borough or state or when the imposition of mass limitations
are appropriate.
A.
The Borough shall evaluate whether each SIU needs an accidental discharge/slug
discharge control plan or other action to control slug discharges.
The Borough may require any industrial user to develop, submit for
approval, and implement such a plan or take such other action that
may be necessary to control slug discharges. Review and approval of
such plans and operating procedures shall not relieve the industrial
user from the responsibility to modify the user's facility as
necessary to meet the requirements of this chapter. Alternatively,
the Borough may develop such a plan for any industrial user. An accidental
discharge/slug discharge control plan shall address, at a minimum,
the following:
(1)
Description of discharge practices, including nonroutine batch discharges;
(2)
Description of stored chemicals;
(3)
Procedures for immediately notifying the Superintendent of any accidental or slug discharge, as required by § 157-16 of this chapter; and
(4)
Procedures to prevent adverse impact from any accidental or slug
discharge. Such procedures include, but are not limited to, inspection
and maintenance of storage areas, handling and transfer of materials,
loading and unloading operations, control of plant site runoff, worker
training, building of containment structures or equipment, measures
for containing toxic organic pollutants.
B.
Notification.
(1)
All industrial users, whether permitted or not, shall immediately
telephone and notify the Borough of all accidental spills, slug discharges
or other discharges that could cause potential problems for the POTW.
This notification shall include the location of the discharge, type
of waste, concentration and volume of waste and any mitigating and/or
corrective actions taken.
(2)
Upon request by the Borough, the industrial user shall also prepare
and submit to the Borough within five days after such notice a detailed
written report describing the cause of the discharge and the measures
to be taken by the user to prevent any similar occurrences in the
future.
(3)
Such notification shall not relieve the user of any expense, loss,
damage, nor other liability which may be incurred as a result of damage
to the POTW, fish kills or any other damage to person or property;
nor shall such notification relieve the user of any fines, civil penalties
or other liability which may be imposed by this chapter or other applicable
law.
C.
A notice shall be permanently posted on the user's bulletin
board or other prominent place advising employees whom to call in
the event of a dangerous discharge. Employers shall ensure that all
employees who may cause or suffer such a dangerous discharge to occur
are advised of the emergency notification procedure.
