Ord. 15-2003, 12/12/2003]
1. No user shall contribute or cause to be contributed, directly or
indirectly, any pollutant or wastewater which will cause pass through
or interference in the Authority's wastewater collection and
treatment system, will create a hazard to the environment, the general
public or Authority personnel, or will cause the Authority to violate
any General Pretreatment Regulation, NPDES permit or biosolids requirement.
These general prohibitions, apply to all such users of the POTW, whether
or not the user is subject to National categorical pretreatment standards
or any other National, State or local pretreatment standards or requirements.
A user may not contribute the following substances to the POTW;
A. Explosive Matter.
(1)
Any liquids, solids or gases which by reason of their nature
or quantity are, or may, by sufficient either alone or my interaction
with other substances to create fire or an explosive hazard or be
injurious in any other way to the POTW or to the operation of the
POTW including, but not limited to, waste streams with a closed-cup
flash point of less than 140° F. (60° C.) using the test methods
specified in 40 CFR 261.21.
(2)
At no time shall two successive readings on an explosion hazard
meter at the point of discharge into the 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. Prohibited materials include,
but are not limited to, gasoline, kerosene, naphtha, benzene, toluene,
xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates,
per chlorates, bromates, carbides, hydrides and sulfides.
B. Solid or viscous substances which may cause obstruction to the flow
in a sewer, or pass through or cause other interference with the operation
of the wastewater treatment facilities or collection system, such
as, but not limited to, grease, garbage with particles greater than
1/2 inch in any dimension, animal guts or tissues, paunch manure,
bones, hair, hides, fleshings, entrails, whole blood, feathers, ashes,
cinders, sand, mud, 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 of lubricating oil, and residues from
grinding or polishing processes.
C. Any wastewater having a pH less than — 6.0 or greater than
— 9.0, or wastewater having any other corrosive property capable
of causing damage or hazard to structures, equipment, and/or personnel
of the POTW or the wastewater collection system. At the Borough of
Conshohocken Authority's discretion, an industrial user may be
permitted for a minimum pH of 5.0 and a maximum pH of 10.
D. Any wastewater containing toxic pollutants in sufficient quantity,
either singly or by interaction with other pollutants, to injure or
to cause interference with any wastewater treatment process, to constitute
a hazard to the environment, humans or animals, to create a toxic
effect in the POTW or the receiving waters, or to 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 § 307(a) of the Act.
E. Any noxious or malodorous liquids, gases or solids which either singly
or by interaction with other wastes, are present in sufficient concentrations
to create a public nuisance or hazard to life, cause health and safety
problems, or are sufficient to prevent entry into the sewers for maintenance
and repair.
F. 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.
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 § 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
Substance Control Act, or State criteria applicable to the sludge
management method being used.
G. Any substance which alone or in conjunction with other discharges
will cause a pass through at the POTW or cause the POTW to violate
its NPDES permit or the receiving water quality standards.
H. Any wastewater with objectionable color not removed in the treatment
process such as, but not limited to, dye wastes and vegetable tanning
solutions.
I. Any wastewater having a temperature which will inhibit biological
activity in the POTW treatment plant or collection system resulting
in interference. In no case shall wastewater have a temperature at
the introduction into the POTW which exceeds 40° C. (104°
F.).
J. Any wastewater containing pollutants, including oxygen demanding pollutants (CBOD, BOD, etc.) released in a discharge at a flow rate and/or pollutant concentration which either singly or by interaction with other pollutants will cause interference to the POTW or any wastewater treatment or sludge process, or which will constitute a hazard to humans or animals. In no case shall a slug load have a flow rate or contain concentrations or quantities or pollutants that exceed for any time period longer than 15 minutes more than five times the average twenty-four-hour concentration, quantities or flow during normal operation. This slug load provision does not relieve the user from meeting the specific pollutant concentrations as identified in
Table 1.
K. Any wastewater containing any radioactive wastes or isotopes of such
half life or concentration as may exceed limits established by the
Superintendent in compliance with applicable State or Federal regulations.
L. Any wastewater which causes a hazard to human life or creates a public
nuisance.
M. Stormwater, surface water, ground water, artisan well water, roof
runoff, subsurface drainage, swimming pool drainage, condensate, deionized
water, noncontact cooling water and unpolluted industrial wastewater,
unless specifically authorized by the Superintendent.
N. Petroleum oil, nonbiodegradable cutting oil or products of mineral
oil origin in amounts that will cause interference or pass through.
O. Any pollutants which result in the presence of toxic gases, vapors
or fumes within the POTW in a quantity that may cause acute worker
health and safety problems.
P. Any trucked or hauled waste, except at discharge points designated
by the Authority.
Q. Any sludges, screenings or other residues from the pretreatment of
industrial wastes.
R. Any medical wastes, except as specifically authorized by the Authority
in a permit.
2. Grease, oil and sand interceptors (traps) shall be provided when,
in the opinion of the Superintendent and/or the Authority, they are
necessary for the proper handling of liquid wastes containing floatable
grease in such amounts as to cause obstruction to the flow in a sewer
or other interference with the operation of the wastewater treatment
facilities, or any flammable wastes, sand or other harmful ingredients,
except such interceptors shall not be required for private living
quarters or dwelling units. All interceptors shall be of a type and
capacity approved by the Superintendent and the Authority and shall
be located as to be readily and easily accessible for cleaning and
inspection. In the maintaining of these interceptors, the owner(s)
shall be responsible for the proper removal and disposal by appropriate
means of the captured material and shall maintain records of the dates
and means of disposal which are subject to review by the Superintendent
and the Authority. Any removal and hauling of the collected materials
not performed by owner's (owners') personnel must be performed
by currently licensed waste disposal firms.
3. Whenever the Superintendent determines that a user is contributing
to the POTW any of the above enumerated substances in such amounts
as to cause interference with the operation of the POTW, the Authority
shall advise the user of the impact of his contribution on the POTW
and develop effluent limitations for such user to correct the interference
or pass through to the POTW.

Upon the promulgation of the Federal categorical pretreatment
standard under § 307 of the Clean Water Act for a particular
industrial subcategory, the Federal standard, if more stringent than
limitations imposed under this Chapter for sources in that subcategory,
shall be enforceable under this Chapter, per 40 CFR § 403.12.
Each user shall be responsible to notify the Authority of changes
to their status under the Federal, State, or local regulations.
[Ord. 12-1992, 5/13/1992, § 2.5; as amended by
Ord. 15-2003, 12/12/2003]
Where the Authority's wastewater treatment system achieves
consistent removal of pollutants limited by Federal pretreatment standards,
the Authority may apply to the approval authority for modifications
of specific limits in the Federal pretreatment standards. "Consistent
removal — the reduction in the amount of a pollutant
or alteration of the nature of the pollutant by the wastewater treatment
system to a less toxic of harmless state in the effluent which is
achieved by the system in 95% of the samples taken when measured according
to the procedures set forth in § 403.7(c)(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 Authority may then modify pollutant
discharge limits in the Federal pretreatment standards if the requirements
contained in 40 CFR Part 403, § 403.7 are fulfilled and
prior approval from the Approval Authority is obtained.
[Ord. 12-1992, 5/13/1992, § 2.6; as amended by

limitations may be imposed.
[Ord. 12-1992, 5/13/1992, § 2.7; as amended by
Ord. 15-2003, 12/12/2003]
State requirements and limitations on discharges shall apply
in any case where they are more stringent than either Federal requirements
and limitations or those in this Chapter.
[Ord. 12-1992, 5/13/1992, § 2.8; as amended by
Ord. 15-2003, 12/12/2003]
1. The Authority reserves the right to require each of the contributing
municipalities to establish by ordinance and/or Rules and Regulations,
limitations or requirements as least as stringent as the Authority's
wastewater treatment plant, in order to comply with the objectives
presented in (§ 101 of these Pretreatment Regulations).
2. The Borough reserves the right to establish by ordinance or in permits more stringent limitations or requirements on discharges to the wastewater system if deemed necessary to comply with the objectives presented in §
18-101 of this Part or the general and specific prohibitions in Part 1B of this Chapter.
[Ord. 12-1992, 5/13/1992, § 2.9; as amended by
Ord. 15-2003, 12/12/2003]
No user shall ever increase the use of process 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 with
any other pollutant-specific limitation developed by the Authority,
State or Federal agencies.
[Ord. 12-1992, 5/13/1992, § 2.10; as amended by
Ord. 15-2003, 12/12/2003]
Each user designated by the Authority shall provide protection
from accidental or slug discharges of prohibited materials or other
substances that have the potential to cause interference or pass through
at the POTW and are regulated by this Chapter. Slug discharges include
any discharge of a nonroutine, episodic nature including, but not
limited to, and accidental spill or a noncustomary batch discharge.
Facilities to prevent accidental discharges or slug discharges of
prohibited materials shall be provided and maintained at the user's
own cost and expense. Detailed plans showing facilities and operating
procedures to provide this protection shall be submitted to the Authority
and shall be approved by the Authority before construction of the
facility. All existing users shall complete such a plan within 90
days of notification to do so by the Authority. No user who commences
contribution to the POTW after the effective date of this Chapter
shall be permitted to introduce pollutants into the system until the
accidental discharge and slug discharge procedures have been approved
by the Authority. Review and approval of such plans and operating
procedures shall not relieve the user from the responsibility to modify
its facility, as necessary, to meet the requirements of this Chapter.
In the case of an accidental discharge or slug discharge, it is the
responsibility of the user to immediately notify the Superintendent
by telephone of the incident. The notification shall include location
of discharge, type of waste, concentration, volume and corrective
actions.
[Ord. 12-1992, 5/13/1992, § 2.11; as amended by
Ord. 15-2003, 12/12/2003]
1. Within five days following an accidental discharge, the user shall
submit to the Superintendent a detailed written report describing
the cause of the discharge, time and duration of the discharge, steps
taken to reduce and minimize the impact of accidental discharge, and
the measures to be taken to prevent similar future occurrences, to
mitigate any expense, loss, damage or other liability which may be
incurred as a result of damage to the POTW or aquatic life or any
other damage to person or property.
2. Written reports will be deemed to have been submitted on the date
postmarked. For reports which are not mailed, postage prepaid, into
a mail facility serviced by the U.S. Postal Service, the date of receipt
of the report by the Authority shall govern.
[Ord. 12-1992, 5/13/1992, § 2.12; as amended by
Ord. 15-2003, 12/12/2003]
Unless otherwise approved by the Authority, no materials considered
a hazardous waste under 40 CFR, Part 261 shall be mixed with wastewater
that will ultimately enter the Authority wastewater collection system.
[Ord. 12-1992, 5/13/1992, § 2.13; as amended by
Ord. 15-2003, 12/12/2003]
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 an accidental or slug discharge. Employers shall ensure
that all employees who may suffer from, or cause such a discharge
to occur are advised of the emergency notification procedures.
