These general prohibitions apply to all 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 contribute the following substances to the POTW:
A.
Any substance which will pass through and as a result cause the POTW
treatment plant to violate its NPDES permit or the receiving stream's
water quality standards.
B.
Any wastewater containing pollutants in sufficient quantity which,
either singly or by interaction with other pollutants, injures or
interferes with the POTW treatment plant, constitutes a hazard to
humans or animals, creates a toxic effect in the receiving waters
of the POTW treatment plant, or exceeds the limitations set forth
in a federal categorical pretreatment standard.
C.
Any pollutants, including oxygen demanding pollutants (BOD, etc.)
released at a flow rate and/or pollutant concentration which cause
interference to the POTW treatment plant.
D.
Any substance which may cause the POTW treatment plant effluent or
any other product of the POTW treatment plant such as residues, sludges
or scums, to be unsuitable for reclamation or reuse, or to interfere
with the reclamation process. In no case shall a substance discharged
to the POTW cause the POTW treatment plant to be in noncompliance
with sludge use or disposal criteria, guidelines or regulations developed
under Section 405 of the Act; or 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.
E.
Any wastewater having a temperature which may inhibit biological
activity in the POTW treatment plant resulting in interference. Any
wastewater with a temperature at the introduction into the POTW treatment
plant which exceeds 40° C. or 104° F. is prohibited.
F.
Any wastewater with objectionable color not removed in the POTW treatment
process, such as, but not limited to, dye wastes and vegetable tanning
solutions.
G.
Detergents, surface-active agents or other substances which may cause
excessive foaming in the POTW treatment plant.
H.
Any stormwater, surface water, groundwater, roof runoff, subsurface
drainage, swimming pool drainage, noncontact cooling water, unpolluted
industrial or nonresidential process water. The discharge of cooling
water from air-conditioning units with cooling towers or recirculating
systems or from air-conditioning units using flow-through or unrecirculating
systems is prohibited.
I.
Any wastewater having a pH less than 5.0 or more than 11.0, or otherwise
causing corrosive structural damage to the POTW or equipment.
J.
Oils and greases, including petroleum oil, nonbiodegradable cutting
oil, products of mineral oil origin, in amounts greater than 100 mg/L,
and/or fats, oils and greases of animal and vegetable origin, in amounts
greater than 200 mg/L; or contain substances that may solidify or
become viscous at temperatures between 32° F. or 0° C. and
150° F. or 65° C.; or in quantities that may cause operational
or other problems in the sewer collection system or wastewater treatment
plant. In no case shall fats, oils and greases of animal and vegetable
origin, or oils and greases of petroleum and mineral oil origin, be
discharged at a level that, alone or in conjunction with discharges
from other sources, will cause interference or pass through at the
POTW treatment plant.
K.
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 create a hazard of fire or explosion, or
to be injurious in any other way to the POTW, or to the operation
of the POTW, including, but not limited to, wastestreams 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 sewer system (or at any point in the sewer system) be more than
5%, nor any single reading over 10% of the lower explosive limit (LEL)
of the meter. Except as otherwise provided by the VJSA, prohibited
materials include, but are not limited to, gasoline, fuel oil, kerosene,
naphtha, benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes,
peroxides, chlorates, perchlorates, bromates, carbides, hydrides and
sulfides, and any other substance which is a fire hazard or a hazard
to the POTW.
L.
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 or 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 or repair.
M.
Solid or viscous substances which may cause obstruction to the flow
in the sewer system or interfere with the operation of the POTW treatment
plant, including, 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 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, gas, tar, asphalt residues, residues
from refining or processing of fuel or lubricating oil, mud, glass
grinding or polishing wastes.
N.
Any wastewater containing any radioactive wastes or isotopes of such
half-life or concentration as may exceed limits established by the
VJSA in compliance with applicable state or federal regulations. Any
wastewater which causes a hazard to human life or creates a public
nuisance.
Nothing contained in this Part 3 shall be construed as prohibiting
special agreements between the VJSA and an industrial user, or for
the VJSA to otherwise waive requirements hereunder, when conditions
and circumstances making such special agreements or waivers advisable
and/or necessary, in the opinion of the VJSA, are present, provided,
however:
A.
Federal categorical pretreatment standards and prohibitive discharge
standards, including the general and specific prohibited discharge
standards set forth in 40 CFR 403.5(a) and (b), and any other pretreatment
requirements established in 40 CFR 403 shall not be waived, unless
such waiver is granted by mechanisms established under the federal
pretreatment regulations.
B.
In no case shall a special agreement or waiver of local limits allow
for an industrial user to discharge any pollutant which, alone or
in combination with other industrial user regulated discharges, would
reasonably be expected to exceed the mass loadings determined by the
VJSA as acceptable to the POTW treatment plant based upon considerations
of, among other things, interference, pass-through and sludge contamination.
The VJSA may consider other factors (e.g., effect of the discharge
on the POTW treatment plant, future expansion, etc.) as it deems appropriate.
In no event shall any special agreement or waiver allow the total
loading allocated to all industrial users for any pollutant to exceed
the maximum allowable industrial loading set forth in the most recent
local limits technical evaluation.
C.
The VJSA may require an industrial user requesting a special agreement
or waiver adjusting effluent limitations to submit supporting documentation
indicating why the industrial user cannot reasonably expect to meet
effluent limitations contained in its wastewater discharge permit,
setting forth an expeditious schedule for attaining compliance with
such limitations, and including such other information as the VJSA
may require.
D.
In granting any special agreement or waiver, the VJSA may impose
time limitations upon any reduced requirements and a compliance schedule
for achieving full compliance. In granting any special agreement,
the VJSA may impose any other conditions deemed necessary to implement
the purposes of this Part 3 (e.g., treatment or sludge disposal costs).
The VJSA may condition the special agreement or waiver upon the agreement
of the industrial user to pay those costs and to provide security
adequate in the judgment of the VJSA to assure payment of said costs.
E.
All special agreements or waivers shall be requested and granted
in writing.
The federal categorical pretreatment standards found at 40 CFR Chapter 1, Subchapter N, §§ 405 through 471 are hereby incorporated by reference.
A.
When regulated wastestreams, subject to a federal categorical pretreatment
standard, are mixed with unregulated wastestreams, the VJSA may impose
alternate limits using the combined wastestream formula found in 40
CFR 403.6(e).
B.
Where a federal categorical pretreatment standard is expressed only
in terms of either mass or concentration for a pollutant, the VJSA
may impose equivalent concentration or mass limits in accordance with
40 CFR 403.6(c).
C.
When the limits in a federal categorical pretreatment standard are
expressed only in terms of pollutant concentrations, an industrial
user may request that the VJSA convert the limits to equivalent mass
limits. The determination to convert concentration limits to mass
limits is within the discretion of the VJSA. The VJSA may establish
equivalent mass limits only if the industrial user meets all of the
conditions outlined in 40 CFR 403.6(c)(5) as set forth below:
(1)
To be eligible for equivalent mass limits, the industrial user must:
(a)
Employ, or demonstrate that it will employ, water conservation
methods and technologies that substantially reduce water use during
the term of its individual wastewater discharge permit.
(b)
Currently use control and treatment technologies adequate to
achieve compliance with the applicable federal categorical pretreatment
standard and not use dilution as a substitute for treatment.
(c)
Provide sufficient information to establish the facility's actual
average daily flow rate for all wastestreams, based on data from a
continuous effluent flow monitoring device, as well as the facility's
long-term average production rate. Both the actual average daily flow
rate and the long-term average production rate must be representative
of current operating conditions.
(d)
Not have daily flow rates, production levels, or pollutant levels
that vary so significantly that equivalent mass limits are not appropriate
to control the discharge.
(e)
Have consistently complied with all applicable federal categorical
pretreatment standards during the period prior to the industrial user's
request for equivalent mass limits.
(2)
An industrial user subject to equivalent mass limits must:
(a)
Maintain and effectively operate control and treatment technologies
adequate to achieve compliance with the equivalent mass limits.
(b)
Continue to record the facility's flow rates through the use
of a continuous effluent flow monitoring device.
(c)
Continue to record the facility's production rates and notify
the VJSA whenever production rates are expected to be more than 20%
from its baseline production rates determined in paragraph (a)(3)
of this section. Upon notification of a revised production rate, the
VJSA will reassess the equivalent mass limit and revise the limit
as necessary to reflect changed conditions at the facility.
(d)
Continue to employ the same or comparable water conservation
methods and technologies as those implemented pursuant to paragraphs
(a)(1) and (a)(2) of this section so long as it discharges under an
equivalent mass limit.
(3)
When developing equivalent mass limits, the VJSA:
(a)
Will calculate the equivalent mass limit by multiplying the
actual average daily flow rate of the regulated process(es) of the
industrial user by the concentration-based daily maximum and monthly
average standard for the applicable federal categorical pretreatment
standard and the appropriate unit conversion factor.
(b)
Upon notification of a revised production rate, will reassess
the equivalent mass limit and recalculate the limit as necessary to
reflect changed conditions at the facility.
(c)
May retain the same equivalent mass limit in subsequent individual wastewater discharger permits if the industrial user's actual average daily flow rate is reduced solely as a result of the implementation of water conservation methods and technologies, and the actual average daily flow rates used in the original calculation of the equivalent mass limit are not based on the use of dilution as a substitute for treatment pursuant to § 137-71 of this Part 3. The industrial user must also be in compliance with § 137-93.6B of this Part 3 regarding prohibition of bypass.
(d)
The VJSA may not express limits in terms of mass for pollutants
such as pH, temperature, radiation, or other pollutants which cannot
appropriately be expressed as mass.
D.
The VJSA may convert the mass limits of federal categorical pretreatment standards at 40 CFR 414, 419 and 455 to concentration limits for purposes of calculating limitations applicable to individual industrial users. When converting such limits to concentration limits, the VJSA will use the concentrations listed in the applicable subparts of 40 CFR 414, 419 and 455 and document that dilution is not being substituted for treatment as stated in § 137-71 of this Part 3.
E.
An industrial user may obtain a variance from a federal categorical
pretreatment standard if the industrial user proves, pursuant to 40
CFR 403.13, that factors relating to its discharge are fundamentally
different from the factors considered by EPA when developing the federal
categorical pretreatment standard.
F.
An industrial user may obtain a net gross adjustment to a federal
categorical pretreatment standard in accordance with 40 CFR 403.15.
Federal categorical pretreatment standards may be adjusted to reflect
the presence of pollutants in the industrial user's intake water.
G.
Where there is a conflict between federal, state or local pretreatment
standards, the more stringent pretreatment standard shall apply.
H.
Where the POTW treatment plant achieves consistent removal of pollutants
limited by federal categorical pretreatment standards, the VJSA may
apply to the approval authority for modifications of specific limits
in the federal categorical pretreatment standards. Appendices G-I
and G-II contained in 40 CFR 403.7 list those pollutants that are
eligible for removal credits. Removal credits are only available for
the various use and disposal practices regulated under the 40 CFR
503 sludge regulations. "Consistent removal" shall mean the reduction
in the amount of a pollutant or alteration of the nature of the pollutant
by the POTW treatment plant to a less toxic or harmless state in the
effluent in 95% of the samples taken when measured according to the
procedures set forth in 40 CFR 403.7(c). The VJSA may then modify
pollutant discharge limits in the federal categorical pretreatment
standards if the requirements contained in 40 CFR 403.7 are fulfilled
and prior approval from the approval authority is obtained.
Local limits for pollutants of concern, as set forth in the
attached Schedule A,[1] shall be amended by ordinance of the Borough Council to protect against Pass Through and interference, and to protect the sludge quality at the POTW treatment plant. Local limits may be allocated on an individual basis to the industrial users and defined through wastewater discharge permits issued pursuant to § 137-84 of this Part 3. The VJSA may continue to develop these limits as necessary and effectively enforce such limits through this Part 3. Best management practices (BMPs) developed by the VJSA are attached hereto as Schedule B,[2] the same being incorporated herein by reference, and the same may be amended after ordinance approval. Local limits, as set forth in the attached Schedule A; BMPs, as set forth in the attached Schedule B; and the Prohibited Discharge Standards in § 137-66 of this Part 3 may be set forth in individual wastewater discharge permits to allow implementation thereof.
The VJSA reserves the right to establish through wastewater
discharge permits more stringent limitations or requirements on discharges
to the POTW treatment plant if deemed necessary and appropriate to
comply with the objectives presented in this Part 3.
No industrial 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 a discharge
limitation unless expressly authorized by an applicable pretreatment
standard or requirement. The VJSA may impose mass limitations on industrial
users who are using dilution to meet applicable pretreatment standards
or requirements or in other cases when the imposition of mass limits
is appropriate.
Industrial users shall provide necessary wastewater pretreatment as required to comply with this Part 3 and shall achieve compliance with all federal categorical pretreatment standards, local limits and the prohibitions set out in § 137-66 of this Part 3. Any facilities required to pretreat wastewater to a level acceptable to the VJSA shall be provided, operated and maintained at the industrial user's expense.
A.
Detailed plans showing the pretreatment facilities and operating
procedures shall be submitted to the VJSA for review, and shall be
acceptable of the VJSA before construction of the facility. The VJSA
does not by its acceptance of any of the designs or installations
of the plans and equipment, or of any other information or plans submitted
by the industrial user, warrant or aver in any manner that the industrial
user's implementation of such measures will result in compliance with
applicable pretreatment standards and requirements. Notwithstanding
any acceptance of such plans by the VJSA, the industrial user remains
solely responsible for compliance with applicable pretreatment standards
and requirements and all other federal, state and local requirements.
The review of such plans and operating procedures in no way relieves
the industrial user from the responsibility of modifying the facility
as necessary to produce an acceptable discharge to the POTW treatment
plant under the provisions of this Part 3.
B.
Any subsequent changes in the pretreatment facilities or method of operation shall be reported to and be accepted by the VJSA prior to the industrial user's initiation of the changes. The industrial user shall at all times properly operate and maintain all pretreatment facilities and systems of treatment and control (and related appurtenances) which are installed or used by the industrial user to achieve compliance with pretreatment standards and requirements. This includes adequate laboratory controls and appropriate quality assurance procedures, the operation of backup or auxiliary facilities, or similar systems which are installed by the industrial user only when the operation is necessary to achieve compliance. Except as provided by § 137-93.6B of this Part 3, the intentional diversion of wastestreams from any portion of the industrial user's treatment facility is prohibited.
C.
An industrial user, when required by the VJSA, shall construct and
properly maintain at his own expense a suitable control manhole and
other devices to facilitate observation, measurement and sampling
of industrial wastewater. Such control manhole shall be constructed
at an accessible, safe, suitable and satisfactory location in accordance
with plans reviewed and deemed acceptable to the VJSA prior to construction
of such control manhole.
Whenever the VJSA deems it necessary, the VJSA may require an
industrial user to restrict its discharge during peak flow periods;
to discharge at a consistent flow rate; to discharge certain industrial
wastewaters only into specific sewers; to relocate and/or consolidate
points of discharge; to separate domestic wastewater from industrial
wastewater; and to perform and maintain such other conditions as may
be necessary to protect the POTW treatment plant and to determine
the industrial user's compliance with the requirements of this Part
3.
The Borough may require any existing food service establishment
and shall require all new food service establishments to install grease
traps or grease interceptors subject to such terms and conditions
as deemed necessary by the Borough to protect the sewer system and
the POTW treatment plant from excessive amounts of fats, oils and
grease (FOG). Among the factors to be considered by the Borough is
whether the user's discharge has the potential to obstruct the flow
in the sewer system or to interfere with the operation of the POTW
treatment plant.
A.
Sizing of grease interceptors is based on wastewater flow and grease
retention capacity. Indoor grease traps shall be designed in accordance
with the Plumbing and Drainage Institute Standard, PDI-G101.
B.
If feasible, a grease interceptor shall be placed outside the building
instead of an inside grease trap. The minimum size grease interceptor
required is 1,000 gallons. Interceptors can be installed in series
if greater capacity is needed.
C.
Grease interceptors shall be constructed of impervious materials
capable of withstanding abrupt or extreme changes of temperature.
They shall be of substantial construction, watertight and equipped
with easily removable covers which, when bolted in place shall be
gastight and watertight. Other design considerations shall include,
but are not limited to, the following: minimum of two compartments,
each with its own manhole, and a center baffle to allow floating of
FOG and settling of solids; inlet and outlet on grease interceptor
shall be properly baffled; flow control devices; manholes finished
to grade to allow easy access for proper maintenance; cleanout on
outlet side of interceptor; inaccessibility to insects and vermin;
and installation of sample vault with hydraulic jump on discharge
side of interceptor.
D.
Grease traps and grease interceptors shall be located in the service
lateral line between all fixtures that may introduce FOG into the
sewer system and the service connection to the sewer system. Such
fixtures include, but are not limited to, sinks, dishwashers, garbage
disposals, automatic hood wash units, floor drains in food preparation
and storage areas, and any other fixture that may be a potential source
of FOG.
E.
Indoor grease traps will not be approved for food service establishments
that are equipped with dishwashers or garbage disposals.
F.
The trap/interceptor size, type of construction, and the location
of the installation shall be acceptable to the Borough prior to installation.
G.
Grease traps and grease interceptors shall be inspected, cleaned
and repaired regularly, as needed, by the owner at his expense. To
maintain grease traps and grease interceptors in a continuously efficient
operation at all times, the owner shall be responsible for the proper
removal and disposal of the captured material, and shall maintain
records, which include dates of maintenance, person performing maintenance,
estimated volume of FOG removed, hauler receipts or manifests, disposal
locations and facility manager's verification. The frequency of cleaning
shall be as specified by the trap/interceptor manufacturer, based
on the size of the food service establishment and the type of food
served, whichever is more stringent. Such records are subject to review
by the Borough. Borough personnel may make periodic inspections of
the installed facilities and associated records to assure proper operation,
maintenance and disposal procedures are being practiced.
Oil/water separators shall be installed at existing automotive
repair facilities and car washes if the potential exists for petroleum
oils to be discharged to the sewer system via floor drains. New facilities
of this type are prohibited from installing floor drains that are
connected to the sewer system. The type and size of oil/water separator
shall be determined by the owner and shall be acceptable to the Borough
prior to installation. Oil/water separators shall be inspected, cleaned
and repaired regularly, as needed, by the owner at his expense. The
owner shall be responsible for the proper removal and disposal of
the captured material from oil/water separators, and shall maintain
records of the dates and means of disposal. Such records are subject
to review by the Borough. Borough personnel may make periodic inspections
of the installed facilities and associated records to assure proper
operation, maintenance and disposal procedures are being practiced.
Hauled waste may be introduced into the POTW treatment plant
only at locations designated by the VJSA, and at such times as are
established by the VJSA. Such waste shall not violate this Part 3
or any other requirements established by the VJSA.
A.
Waste haulers may be required to obtain a waste hauler permit. In
such cases, the application may, at a minimum, contain the following
information:
(1)
Name, address, location and telephone number.
(2)
Vehicle information.
(3)
Description of wastes to be discharged.
(4)
List of permits held by the applicant for generation, transport and
disposal.
(5)
Estimate of total volume of waste to be discharged at the POTW treatment
plant.
(6)
Name of the authorized representative of the waste hauler.
B.
Waste hauler permits may include, but not be limited to, the following
conditions:
