[Ord. No. 763, 5/7/2020]
1.
No user shall contribute or cause to be contributed, directly or
indirectly, any pollutant or wastewater which will cause pass-through
or interference with the operation or performance of the POTW. These
general prohibitions apply to all such users of a POTW whether or
not the user is subject to categorical pretreatment standards or any
other national, state, or local pretreatment standards or requirements.
A user shall not contribute the following substances to the POTW:
A.
Any liquids, solids, or gases which by reason of their nature or
quantity are, or may be, sufficient either alone or by interaction
with other substances to cause fire or explosion or be injurious in
any other way to the POTW or to the operation of the POTW. 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, perchlorates,
bromides, carbides, hydrides, and sulfides. Waste streams with a closed-cup
flash point of less than 140° F. or 60° C. using the test
methods specified in 40 CFR 261.21 are also prohibited.
B.
Solid or viscous substances which may cause obstruction to the flow
in a sewer or other interference with the operation of the wastewater
treatment facilities such, as, but not limited to, grease, garbage
with particles greater than 1/2 inch in any dimension, animal guts,
animal tissues or wastes, paunch manure, bones, hair, hides or fleshings,
entrails, whole blood, feathers, ashes, cinders, sand, spent lime,
stone or marble dust, metal, glass, straw, shavings, grass clippings,
rags, spent grains, spent hops, waste paper, wood, plastics, tar,
asphalt residues, residues from glass grinding or polishing wastes.
C.
Any wastewater having a pH less than 5.5 S.U. or more than 9.0 S.U.,
or wastewater having any other corrosive property capable of causing
damage or hazard to structures, equipment, and/or personnel of the
POTW.
D.
Any wastewater:
(1)
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, pass-through the POTW and degrade the receiving stream; or
E.
Any noxious or malodorous liquids, gases, or solids which either
singly or by interaction with other wastes are sufficient to create
a public nuisance or hazard to life 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 Section 405 of the Act;[1] 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,[2] or state criteria applicable to the sludge management
method being used.
G.
Any substance which will cause the POTW to violate its NPDES and/or
Pennsylvania DEP stream discharge permit or cause a violation of the
water quality standards of the receiving stream.
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 as it enters the Authority's sewer with a temperature
greater than 50° C. (122° F.) or, when in combination with
other wastewaters, will, increase the temperature of the influent
to the POTW treatment plant above 40° C. (104° F.); or which
heat will inhibit biological activity in the POTW resulting in interference.
J.
Any pollutants, including oxygen-demanding pollutants (BOD, etc.)
released at a flow rate and/or pollutant concentration which will
cause interference to the POTW. In no case shall a slug load have
a flow rate five times the average operating flow rate nor contain
concentrations or quantities of pollutants that exceed at any moment
in time four times the average operating values.
K.
Any wastewater containing any radioactive wastes or isotopes.
L.
Any wastewater which causes a hazard to human life or creates a public
nuisance.
M.
Any wastewater containing any organic chemical from the list hereafter
in any amount whatsoever:

and safety problems.
[Ord. No. 763, 5/7/2020]
1.
Clean water discharges into the POTW unnecessarily consume sewer
and treatment plant capacities as well as reduce the effectiveness
of the wastewater treatment processes and, therefore, the discharge
of clean water is unacceptable to the Authority.
2.
Specifically, no person shall discharge or cause to be discharged
any unpolluted waters such as water from sump pumps, floor drains,
stormwater, groundwater, roof runoff, subsurface drainage, foundation
drainage, or cooling water into the POTW. Storm water and all other
unpolluted drainage shall be discharged to such sewers that are specifically
designed as storm sewer or to a natural outlet. Industrial cooling
water or unpolluted process waters may be discharged to a storm sewer
or natural outlet upon the issuance of a permit to do so from the
U.S. EPA or the Pennsylvania Department of Environmental Protection.
[Ord. No. 763, 5/7/2020]
1.
Upon the promulgation of the categorical pretreatment standards for a particular industrial subcategory, the national standard (located in 40 CPR Chapter I, Subchapter N, Parts 405 through 471), if more stringent than limitations imposed under this Part 1, Articles A through F, for sources in the subcategory, shall immediately supersede the limitations imposed under this Part 1, Articles A through F, and shall be incorporated herein by reference. The Authority Manager shall notify all affected users of the applicable reporting requirements under 40 CFR 403.12.
2.
The Authority may also require, if deemed necessary by the Authority
Manager, that the pollutants discharged by the user be segregated
from sanitary sewage. This will require the installation of a separate
drainage system sewer line exclusively for such pollutants and that
system shall remain segregated until passage through a sampling and/or
monitoring facility, at which time it may join the building's
sanitary drain for continuation and connection to the Authority's
sewer lateral.
[Ord. No. 763, 5/7/2020]
1.
The following limits of concentration are given for guidance to all
existing and proposed users to the POTW. The tabulation represents
the maximum permissible concentration of each specific parameter acceptable
in a discharge when averaged over any twenty-four-hour operating period.
The acceptable peak concentration of any substance at any given moment
shall not exceed the concentration limits listed herein. Lower concentrations
may be required of a pollutant if, in the judgment of the Authority,
it is necessary to do so in order to protect the POTW processes, its
sludge quality, and its effluent quality.
2.
The Authority may take, at its sole discretion, materials that are
generally considered compatible with the sewage treatment plant and
its processes, that is, materials that are commonly associated with
domestic waste, at concentrations greater than those listed under
the daily maximum limit; however, a surcharge will be applied for
the treatment and/or handling of the unusually strong pollutants in
accordance with the formula and rate schedule on file at the Administration
Office of the Warminster Township Municipal Authority. Pollutants
having all characteristics at or below the twenty-four-hour limits
will not be subject to a surcharge.
3.
Pollutants having any characteristic beyond any limit value, as shown
in the following table, shall be rejected.
4.
Extra strong pollutants, with surcharge, shall be applicable to BOD,
COD, total dissolved solids, total suspended solids, phosphates, chlorides,
sulfates, ammonia nitrogen, nitrate nitrogen, organic nitrogen, iron,
aluminum, and oil and grease. Additional and more specific limitations
may be contained within the user's wastewater discharge permit, which
shall be binding control values.
5.
The following list is subject to additions and modifications as required
of the Authority by regulatory agencies or as technical revelations
may dictate to the Authority that it is prudent to revise the values
tabulated. As tens of thousands of various pollutants exist, the list
is not a tabulation of all substances that are or may be restricted
by the Authority.

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 waste treatment or waste control to achieve compliance with the limitations contained in this Part 1, Articles A through F, or in any categorical pretreatment standard, or in any other pollutant-specific limitation developed by the Township or state.
[Ord. No. 763, 5/7/2020]
1.
The user shall provide protection from accidental discharge to the sewer of prohibited or controlled materials or other substances regulated by this Part 1, Articles A through F. In the application for a wastewater discharge permit, the applicant shall provide a narrative detailing what facilities and/or operating procedures are, or shall be, employed to preclude an accidental discharge. The issuance of a wastewater discharge permit shall be contingent upon the submission of an acceptable spill control plan.
2.
In case of an accidental discharge, the user shall immediately telephone
and notify the Authority of the incident. During normal working hours
the user shall notify the Authority Manager, or his assistant at 215-675-3301
and during non-office hours notify the Chief Operator at the sewage
treatment plant, telephone number 215-675-6113.
3.
When requested by the Authority, a user shall develop a slug control
plan which outlines discharge practices (including nonroutine batch
discharges), describes stored chemicals and which contains procedures
both to notify the POTW immediately of slug discharges or if any changes
at its facility affecting the potential for a slug discharge and to
prevent, adverse impacts from accidental spills. The plan must be
posted within the building in such a manner that all employees can
see the plan. Furthermore, the plan must list the following information:
A.
Names and telephone numbers of people to be contacted within the
company;
B.
Names and addresses of people outside the company who may need to
be contacted;
C.
All emergency equipment on hand, the location of such emergency equipment
and the names and telephone numbers of people who can handle such
emergency equipment;
D.
Procedures to follow in case of a chemical spill; and
E.
The location of the material safety data sheets (SDS) which must
be on site for all chemicals and products used in the company's
business.
4.
Written Notice. Within five days following an accidental discharge,
the user shall submit to the Authority Manager a detailed written
report describing the cause of the discharge and the measures to be
taken by the user to prevent similar future occurrences. Such notification
shall not relieve the user of any expense, loss, damage, or 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 article or other applicable
law.
5.
Notice to Employees. A notice shall be permanently posted on the
user's bulletin board or at the place of operations or other
prominent place, advising employees whom to call in the event of a
dangerous discharge. Employers shall ensure that all employees who
are aware of or may cause such a dangerous discharge to occur are
advised of the emergency notification procedures.
