It shall be unlawful for any person to place, deposit or permit
to be deposited in any unsanitary manner on public or private property
within the Borough or in any area under the jurisdiction of the Borough
any sanitary sewage or industrial waste except as provided in this
chapter.
It shall be unlawful to discharge into any natural outlet within
the municipality any wastewater or other polluted waters, except where
suitable treatment has been provided and where a National Pollutant
Discharge Elimination System permit has been obtained from the appropriate
governmental authority, where required.
No person shall discharge or cause to be discharged any stormwater,
surface water, groundwater, roof runoff, subsurface drainage, swimming
pool water, uncontaminated cooling water or unpolluted industrial
process waters to any sanitary sewer, except with the prior written
consent of both the municipality and the PVSC. Stormwater and all
other unpolluted drainage shall be discharged to such sewers as are
specifically designated as storm drains or to a natural outlet approved
by the Engineer. Industrial cooling water or unpolluted process water
may be discharged, on approval of the Engineer, to a storm drain or
natural outlet.
A.
No person shall discharge or cause to be discharged the following
described substances, materials, waters or wastes if it appears likely,
in the opinion of the Engineer with consultation of the governing
body, that such wastes can harm either the sewers, sewage treatment
process or equipment, have an adverse effect on the receiving stream
or can otherwise endanger life, limb, public property or constitute
a nuisance. In forming his opinion as to the acceptability of these
wastes, the Engineer will give consideration to such factors as the
quantities of subject wastes in relation to flows and velocities in
the sewers, materials of construction of the sewers, nature of the
sewage treatment process, capacity of the sewage treatment plant,
degree of treatability of wastes in the sewage treatment plant and
other pertinent factors.
B.
The following wastes are prohibited and may never be discharged into
wastewater facilities of the municipality and PVSC:

Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive
liquid, solid or gas.
(2)
Any waters or wastes containing toxic or poisonous solids, liquids
or gases in sufficient quantity, either singly or by interaction with
other wastes, to injure or interfere with any sewage treatment process,
constitute a hazard to humans or animals, create a public nuisance
or create any hazard in the receiving waters of the sewage treatment
plant, including but not limited to cyanides in excess of two milligrams
per liter as CN in the wastes as discharges to the public sewer.
(3)
Solid or viscous substances in quantities or of such size capable
of causing obstruction to the flow in sewers or other interference
with the proper operation of the sewerage systems, such as but not
limited to ashes, cinders, sand, mud, straw, shavings, metal, glass,
rags, feathers, tar, plastics, wood, unground garbage, whole blood,
paunch manure, hair and fleshings, entrails and paper dishes, cups,
milk containers, etc., either whole or ground by garbage grinders.
C.
The following wastes may not be discharged without special permission
from the PVSC, upon a determination by the PVSC that the discharge
would not be detrimental to the system:
(1)
Any liquid or vapor having a temperature higher than 150° F.
or 65° C.
(2)
Any water or waste containing fats, wax, grease or oils, whether
emulsified or not, in excess of 100 milligrams per liter or containing
substances which may solidify or become viscous at temperatures between
32° F. and 150° F. 0° C. and 65° C.

Any waters or wastes containing strong acid from pickling wastes
or concentrated plating solutions, whether neutralized or not.
(5)
Any waters or wastes containing iron, chromium, copper, zinc and
similar objectionable or toxic substances or wastes exerting an excessive
chlorine requirement to such degree that any such material received
in the composite sewage at the sewage treatment works exceeds the
limits established by the Engineer for such materials.
(6)
Any waters or wastes containing phenols or other taste- or odor-producing
substances in such concentrations exceeding limits which may be established
by the Engineer as necessary after treatment of the composite sewage
to meet the requirements of the state, federal or other public agencies
of jurisdiction for such discharge to the receiving waters.
(7)
Any radioactive wastes or isotopes of such half-life or concentration
as may exceed limits established by the Engineer in compliance with
applicable state or federal regulations.
(8)
Any waters or wastes having a pH in excess of 9.5.
(9)
Materials which exert or cause:
(a)
Unusual concentration of inert suspended solids, such as but
not limited to fuller's earth, lime slurries and lime residues, or
of dissolved solids, such as but not limited to sodium chloride and
sodium sulfate.
(b)
Excessive discoloration, such as but not limited to dye wastes
and vegetable tanning solutions.
(c)
Unusual BOD, chemical oxygen demand or chlorine requirements
in such quantities as to constitute a significant load on the sewage
treatment works.
(d)
Unusual volume of flow or concentration of wastes constituting
slug or sludge as defined herein.
(10)
Waters or wastes containing substances which are not amenable
to treatment or reduction by the sewage treatment processes employed
or are amenable to treatment only to such degree that the sewage treatment
plant effluent cannot meet the requirements of other agencies having
jurisdiction over discharge to the receiving waters.
(11)
Any waters or wastes having a pH lower than 5.5 or having any
other corrosive property capable of causing damage or hazard to structures,
equipment and personnel of the sewerage system.
If any waters or wastes are discharged or are proposed to be discharged to the public sewers, which waters contain the substances or possess the characteristics enumerated in § 399-47 and which, in the judgment of the Engineer, may have a deleterious effect upon sewerage works, processes, equipment or receiving waters or which otherwise create a hazard to life or constitute a public nuisance, the Engineer may:
A.
Reject the wastes.
B.
Require pretreatment to an acceptable condition for discharge to
the public sewers.
C.
Require control over the quantities and rates of discharge.
D.
Require payment to cover the added cost of handling and treating
the wastes not covered by existing taxes or sewer charges under the
provisions of this chapter. If the Engineer permits the pretreatment
or equalization of waste flows, the design and installation of the
plants and equipment shall be subject to the review and approval of
the Engineer and subject to the requirements of all applicable codes,
ordinances and laws.
A.
Grease oil and sand interceptors shall be provided when, in the opinion
of the Plumbing Inspector, they are necessary for the proper handling
of liquid wastes containing grease in excessive amounts or any flammable
wastes, sand or other harmful ingredients, except that such interceptors
shall not be required for private living quarters or dwelling units.
All interceptors shall be of a type and capacity as defined in the
Uniform Construction Code approved by the Plumbing Inspector and shall
be located so as to be readily and easily accessible for cleaning
and inspection.
B.
Grease and oil interceptors shall be constructed of impervious materials
capable of withstanding abrupt and extreme changes in temperature.
They shall be of a substantial construction, watertight and equipped
with easily removable covers which, when bolted in place, shall be
gastight and watertight.
C.
Where installed, all grease, oil and sand interceptors shall be maintained
by the owner, at his expense, in continuously efficient operation
at all times.
D.
Grease traps are required for all waste outlets from all grease-producing
establishments. The type and manufacture of grease traps must be approved
by the Plumbing Inspector and the Sewer Department before installation.
E.
Each grease-producing establishment shall be required to control
oil and grease discharges, as follows:
(1)
Where outside space permits, an exterior grease trap shall be located
and installed subject to the approval of the Plumbing Inspector.
(2)
Where outside space does not permit the installation of an exterior
grease trap, an interior grease trap shall be installed subject to
the approval of the Plumbing Inspector.
(3)
The sizing of the grease trap shall be as determined by the user's
professional engineer licensed in the State of New Jersey. The data
showing the sizing of the grease trap shall be submitted for approval
of the Plumbing Inspector.
(4)
A bacterial pretreatment program shall be developed and implemented
by the user of the grease-producing establishment so as to ensure
that the grease-producing establishment's effluent will not exceed
the grease and oil limitations as established in this chapter. The
bacterial treatment program shall be subject to review and approval
by the Sewer Department.
F.
No new grease trap shall be installed adjacent to, or immediately
downstream from, a hot water source.
G.
Each new grease-producing establishment shall furnish the following
information to the Sewer Department prior to obtaining a building
permit and before discharging any effluent to the municipal sewer
system:
(1)
Description of the establishment, including number of employees,
number of patrons, number of seats, frequency of seating and type
of grease-producing facility;
(2)
Listing of fixtures, including but not limited to dishwashers and
other grease-producing units, describing their function and volume;
(3)
Listing of drain outlets, sizes or trap sizes at each fixture;
(4)
Total annual water use and daily minimum and maximum use; and
(5)
Expected concentrations of grease and oil (as estimated from similar
establishments.)
H.
Each existing grease-producing facility shall also be subject to the terms and conditions of Subsection G above, except that said facility shall have 90 days from the date of adoption of this chapter and notice by the Plumbing Inspector to bring such facility into compliance.
I.
All exterior grease trap chambers shall be constructed of noncorrosive
materials, such as reinforced concrete or fiberglass. The chamber
shall be capable of sustaining ten-ton truck loading and shall have
baffles and fittings made of noncorrosive materials. Access shall
be available to twenty-four-inch manhole frames and covers located
at the end of the chamber.
J.
Each grease-producing establishment shall provide a grease trap maintenance
program to the Sewer Department for approval, prior to initial operation
and/or prior to issuance of a certificate of occupancy. The frequency
of grease removal is dependent upon the capacity of the interceptor
and the quantity of grease in the wastewater. Maintenance intervals
may vary from once a week to once in several weeks, but in no event
more than once monthly. When the grease-removal interval has been
determined for a specific installation, regular cleaning at the interval
is necessary to maintain the rates efficiency of the interceptor.
After the accumulated grease and waste material has been removed,
the interceptor shall be checked to make sure that the inlet, outlet
and air relief ports are clear of obstructions such as solidified
grease. When deemed necessary, there shall be a visual inspection
of grease traps by the Sewer Inspector on a quarterly basis at grease-producing
establishments.
K.
Records must be kept of all maintenance on grease traps. The record
must be made available for inspection by Borough representatives,
upon request, during normal business hours. The record shall include
the following information: date, time, description of work done, comments
on the results of the work done, comments on the additional work needed,
quantity of grease removed, and the names of personnel performing
the work. Any establishment that fails to provide such records or
provides inadequate records shall be subject to a penalty and/or termination
of service.
Prior to issuance of a certificate of occupancy for a grease-producing
establishment in which a grease interceptor is required, the applicant
shall pay an initial fee of $150 to the Borough Clerk. An annual fee
of $150 shall thenceforth be payable to the Borough Clerk to cover
the Borough's costs for inspecting grease interceptors, for enforcement
of the requirements of this chapter. Existing grease-producing establishments
having a grease trap shall also pay an annual fee of $150.
The Plumbing Inspector, Health Officer or other designated person
shall administer the provisions of this article.
Violations of any of the provisions of the within article or
any permit issued under the authority of the within article may result
in the termination of the permit and/or the termination of the authority
to discharge into the system.
