[Added 9-4-2007 by Ord. No. 31-2007]
[Amended 12-21-2021 by Ord. No. 33-2021; 2-1-2022 by Ord. No. 3-2022]
The City of Millville is the owner and NJDEP
permittee of the municipal wastewater treatment facility and sanitary
sewage collection system. The City has established regulations for
sanitary sewage dischargers within the municipal service area. The
following regulations are hereby established to protect the public
health, safety and welfare. These regulations are established to aid
in the prevention of sanitary sewer blockages, odors, and obstructions
from contributions and accumulations of fats, oils, and greases into
the municipal sewer system from commercial or industrial establishments,
particularly food preparation and serving facilities. Such clogs can
result in sewer backups into homes or local waterways and result in
increased maintenance costs of the collection system and treatment
facility.
As used in this article, the following terms
shall have the meanings indicated unless the context clearly indicates
that a different meaning is intended.
Those establishments primarily engaged in activities of preparing,
serving, or otherwise making available for consumption, foodstuffs
and that use one or more of the following preparation activities:
cooking by frying (all methods), baking (all methods), boiling, blanching,
roasting, toasting, or poaching. Also included are infrared heating,
searing, barbecuing and any other food preparation activity that produces
a hot, nondrinkable food product in or on a receptacle that requires
washing. Users are including, but not limited to, cafeterias, hospitals,
hotels, restaurants (including fast food establishments), church halls,
school kitchen operations, supermarket food processing areas, or other
nonresidential establishments.
Organic polar compounds derived from animal and/or plant
sources that contain multiple carbon chain triglyceride molecules.
These substances are detectable and measurable using analytical test
procedures established in 40 CFR 136, as may be amended from time
to time. All are sometimes referred to herein as F.O.G. (fats, oils,
greases).
A device for separating and retaining waterborne F.O.G. complexes
prior to the wastewater exiting the trap and entering the sanitary
sewer collection and treatment facility. These devices also serve
to collect settable solids, generated by and from food preparation
activities, prior to the water exiting the trap and entering the sanitary
sewer collection and treatment system. Grease traps and interceptors
are sometimes referred to as "grease interceptors."
The design features of a grease interceptor and its ability
or volume required to effectively intercept and retain F.O.G. from
grease-laden wastewaters discharged to the public sanitary sewer.
Those establishments primarily engaged in the preparation
of precooked foodstuffs that do not include any form of cooling. These
include cold dairy and frozen foodstuffs preparation and serving establishments.
Any person, including those located outside the jurisdictional
limits of the municipality, who contributes, causes or permits the
contribution or discharge of wastewater into the POTW. This includes
persons who contribute such wastewater from mobile sources such as
those who discharge hauled wastewater.
A.
Grease interceptors shall be installed by users as
required by the City Engineer, Superintendent of the Sewer Utility
or their designee. Grease interceptors shall be installed at the user's
expense, when such user operates a cooking establishment. Grease interceptors
may also be required in noncooking or cold dairy and frozen foodstuffs
establishments and other industrial or commercial establishments when
they are deemed necessary by the City Engineer, Superintendent of
the Sewer Utility, or their designee for the proper handling of liquid
wastes containing F.O.G. No user shall allow wastewater discharge
concentration from subject grease interceptor to exceed 30 milligrams
per liter. All grease interceptors shall be of a type, design, and
capacity easily accessible for user cleaning and City inspection.
All such grease interceptors shall be inspected and serviced as required
in order to maintain minimum design capacity or effective volume of
the grease interceptor, or not less often than every 30 days.
[Amended 12-21-2021 by Ord. No. 33-2021; 2-1-2022 by Ord. No. 3-2022]
B.
Users who are required to pass water through a grease
interceptor shall:
(1)
Provide for a minimum hydraulic retention time at
actual peak flow and at the calculated theoretical peak flow rate
as predicted by the Uniform Plumbing Code fixture criteria, between
the influent and effluent baffles with 20% of the total volume of
the grease interceptor being allowed for sludge to settle and accumulate,
identified hereafter as a "sludge blanket."
(2)
Remove any accumulated grease cap and sludge blanket
as required, but at intervals of not longer than 90 days at the user's
expense. Grease interceptors shall be kept free of inorganic solid
materials such as grit, rocks, gravel, sand, eating utensils, cigarettes,
shells, towels, rags, etc., which could settle and thereby reduce
the effective volume of the grease interceptor.
(4)
Operate the grease interceptor in a manner so as to maintain said device such that attainment of the grease limit is consistently achieved. "Consistently" shall mean any wastewater sample taken from said grease interceptor shall be subject to terms of numerical attainment described in Subsection A above. If an establishment desires, because of documented space constraints, an alternate to an out-of-building grease interceptor, the request for an alternative location shall contain the following information:
(5)
Understand and agree that: The use of biological additives
as an F.O.G. degradation agent is conditionally permissible, upon
prior written approval by the City Engineer and the Sewer Utility
Superintendent. Any establishment using this method of F.O.G. abatement
shall maintain the trap or interceptor in such a manner that attainment
of the F.O.G. wastewater discharge limit as measured from the trap's
outlet is consistently achieved.
(6)
Understand and agree that: The use of automatic F.O.G.
removal systems is conditionally permissible upon prior written approval
by the City Engineer and the Sewer Utility Superintendent, the Lead
Plumbing Inspector of the City of Millville, the County Department
of Health, and the NJDEP. Any establishment using this equipment shall
operate the system in such a manner that the attainment of the F.O.G.
wastewater discharge limit, as measured from the unit's outlet, is
consistently achieved.
(7)
Understand and agree that: F.O.G. recovered on site
for off-site disposal shall meet the following minimum requirements:
(a)
All solid wastes shall be stored in appropriate
containers.
(b)
Users and disposers shall comply with all applicable
hazardous waste regulations of the NJDEP and the NJDOT.
(c)
Users shall maintain records of types and volumes
of all waste generated. These records must be maintained for a period
of five years.
(8)
Understand and agree that: The City Engineer and the
Sewer Utility Superintendent reserve the right to make determinations
of grease interceptor adequacy and need, based on review of all relevant
information regarding grease interceptor performance, facility site
and building plan review and to require repairs to or modifications
or replacement of such traps.
C.
The user shall maintain a written record of grease
interceptor maintenance for five years. All such records will be available
for inspection by the City at all times.
D.
Non-F.O.G.-laden sources are not allowed to be connected
to sewer lines intended for grease interceptor service.
E.
No wastewater in excess of 140° F. (60° C.)
shall be discharged into a grease interceptor.
F.
Grease interceptors shall be installed as required by these regulations. Except as provided herein, for a period of one year following the adoption of these regulations, no enforcement actions will be taken under these regulations for failure to achieve limits on F.O.G. discharges from grease interceptors. If, during this one-year period, an obstruction of a City sewer main(s) occurs that causes a sewer overflow to the extent that an impact on the environment is realized and that said overflow or failure of the sanitary sewer collection system to convey sewage can be attributed in part or in whole to an accumulation of F.O.G. in the City's sewer main(s), the City will take appropriate enforcement actions as stipulated in § 56-76, Violations and penalties, against the generator or contributor of such F.O.G.
G.
Access manholes, with a minimum diameter of 24 inches,
shall be provided over each chamber and sanitary tee. The access manholes
shall extend at least to finished grade and be designed and maintained
to prevent water inflow or infiltration. The manhole shall also have
readily removable covers to facilitate inspection, residuals removal,
and wastewater sampling activities.
A person violating any of the provisions of
these regulations, any provision of the pretreatment standards for
sewerage, N.J.S.A. 58:11-49 et seq., N.J.A.C. 7:14 et seq., or any
regulations promulgated thereunder, shall be liable for a penalty
of not more than $50,000 per day (N.J.S.A. 58:11-49). If the violation
is of a continuing nature, each day shall constitute a separate and
distinct violation. The City shall seek penalties as referenced in
the City's Emergency Response Plan. In accordance with N.J.A.C. 7:14-8.1(f),
the City shall assess the following civil administrative penalty assessments:
A.
The City shall assess a mandatory minimum penalty
of not less than $1,000 for each serious violation as defined in N.J.A.C.
7:14-8.16.
B.
The City shall assess a mandatory minimum penalty
of not less than $5,000 for each violation that causes a violator
to be, or continue to be, a significant noncomplier as defined in
N.J.A.C. 7:14-8.16.
C.
Each violation, including each parameter that is required
to be monitored, sampled and reported and that is not monitored, sampled
and reported, is an additional, separate and distinct violation. Each
day during which a violation continues shall constitute an additional,
separate distinct violation.
D.
The requirement that the City assess penalties pursuant
to the City's Enforcement Response Plan shall in no way be construed
to limit the ability of the City to assess a penalty, bring an action
for a penalty for a violation at any time after a violation occurred,
or to assess a more stringent penalty against a person pursuant to
the City's Enforcement Response Plan.
E.
The City Engineer; Sewer Utility Superintendent or
their designee shall issue a notice of violation. The notice of violation
shall be sent by certified mail, return receipt requested, to the
offending party. The offending party will be directed to show why
service should not be terminated or penalties imposed. Notice shall
be served on the offending party to show why enforcement action should
not be taken.
The City is providing the following information
to assist the user in meeting the requirements set forth in these
rules and regulations. The City is not making any representations
or warranties concerning the information being provided.
A.
A sample copy of a grease system cleaning log is attached.
Users should begin utilizing the sample form or one that suits their
own requirements as long as the form used contains all of the information
which is on the sample form. These records shall be maintained on
file for review by inspectors and for later submission to the Municipal
Sewer Utility as provided in these rules and regulations.
B.
A list of oil and grease haulers and recyclers who
are available to assist users in cleaning and/or removing accumulated
grease is set forth below. The City is not recommending any particular
