and purpose.
To aid in the prevention of sanitary sewer
blockages and adverse impacts to the wastewater treatment facility
and receiving stream from discharges and accumulation of fats, oils
and grease into the sewer system from industrial or commercial establishments,
particularly food preparation and serving facilities.
2.
Description.
The purpose of a grease trap is to remove fats, oil and grease
from sewage prior to discharge to the public sewer. These interceptors
serve as small flotation chambers where fat, grease and oil rise to
the water surface and are retained, while the clear water underneath
is discharged. The use of the word “interceptor” is interchangeable
with the word “trap”.
3.
Applicability.
The following types of facilities will be required to have grease
traps: restaurants, food cooking or food preparation businesses using
any baking, frying, grilling, sauteing, rotisserie, barbecuing, broiling,
boiling, blanching, roasting, toasting or poaching operations, cafeterias,
institutional kitchens, schools, hospitals, nursing homes, service
stations, car washes, vehicle repair and lubrication businesses and
any other facility that handles fats, oils and grease and which discharges
wastewater containing grease into the public sewer system. All such
establishments are required to have a properly sized, functioning
and maintained grease trap.
4.
New
facilities.
Upon the effective date hereof, food service
facilities which are newly proposed or constructed, or existing facilities
which will be expanded or renovated to include a food service facility,
where such facility did not previously exist, or any food service
facility which changes ownership or lease which does not have properly
sized or operational grease trap, shall be required to install, operate
and maintain a grease trap meeting the requirements of this chapter.
Grease traps shall be permitted and installed prior to the issuance
of certificate of occupancy.
5.
Existing
facilities.
For the purposes of sizing and installation
of grease traps, all food service facilities existing within the town
prior to the effective date hereof will be permitted to operate and
maintain existing grease traps provided its grease traps are in efficient
operating condition. After the effective date hereof the town may
require an existing food service facility to install, operate and
maintain a new grease trap that complies with the requirements of
this chapter or to modify or repair any noncompliant plumbing or existing
trap within ninety (90) days of written notification by the town when
any of the following conditions exist:
a.
The facility is found to be contributing fats, oils and grease in
quantities sufficient to cause line stoppages or necessitate increased
maintenance on the public sewer system.
b.
The facility does not have a grease trap.
c.
The facility has an undersized, irreparable or defective grease trap.
d.
Remodeling of the food preparation or kitchen waste plumbing is performed
which requires a plumbing permit to be issued by the town.
e.
The existing facility is sold or leased or undergoes a change of
ownership.
f.
The existing facility does not have plumbing connections to a grease
trap in compliance with the requirements of this chapter.
6.
Grease
trap requirements.
a.
Plumbing connections.
Grease traps, generally, shall
be designed for exterior installation and shall be located in the
food service facility’s lateral sewer line between all fixtures
which may introduce grease into the sewer system and the connection
to the public sewer. Such fixtures shall include, but not be limited
to, sinks, dishwashers, except that only the pre-rinse cycles may
be discharged to the grease trap and all other dishwasher wastewater
must bypass the grease trap, garbage disposals, automatic hood wash
units, floor drains in food preparation and storage areas and any
other fixture determined to be a potential source of grease. Wastewater
from sanitary facilities and other similar fixtures shall not be introduced
into the grease trap under any circumstances. Grease traps shall be
designed, located and constructed to facilitate easy access and maintenance
by the owner and inspection by the town.
b.
Interior or under-sink traps.
Interior grease traps
shall be prohibited for new or remodeled food service facilities,
except where, in the determination of the public utilities director,
inadequate space is available for installation of an exterior grease
trap. If the public utilities director grants approval for installation
of an interior or under-sink grease trap unit, then such approval
shall require written agreement of the owner or lessee to inspect,
clean and maintain the unit at least weekly and to skim the grease
out of such grease trap and place in a holding container of at least
fifty-five (55) gallons for pickup by a commercial grease hauler.
Grease traps approved for interior installation shall be equipped
with a flow control device to limit flow through the unit so as not
to exceed the manufacturer’s rated capacity in gallons per minute
for the unit. The flow control device and the grease trap shall be
vented at least six inches (6") above the flood rim level.
c.
Grease trap design.
(1)
Access manholes.
Grease traps will be equipped with
an access manhole with a minimum diameter of twenty-four inches (24")
and shall be provided over each chamber and sanitary tee. Access manholes
shall extend at least to finished grade and be designed and installed
to prevent inflow or infiltration.
(2)
Capacity.
Grease traps shall have sufficient capacity
to perform the service for which it is provided. Traps shall be designed
for a minimum hydraulic detention time of twenty-four (24) minutes
at actual peak flow rate or twelve (12) minutes of calculated peak
flow rate as predicted by the Uniform Plumbing Code fixture criteria,
between the influent and effluent baffles, with twenty percent (20%)
of the total volume of the trap allowed for sludge to settle and accumulate.
Both the inlet and outlet of the grease trap shall have adequate baffles
to prevent short circuiting of waste through the trap. The minimum
passive capacity for any grease trap regardless of projected discharge
shall be no less than five hundred (500) gallons.
(3)
Flow through rate.
Because it is necessary for fats,
oils and grease to cool down to solidify, grease traps shall be designed
with a horizontal flow through rate not to exceed 0.25 inch per second.
The flow through rate is to be calculated for a given tank with its
maximum grease storage and sludge storage volume factored into the
calculation.
(4)
Approval of plans.
The owner or permittee of any business
required to install a grease trap shall submit a site plan showing
the location of the trap, sewer lines and cleanouts, details of the
grease trap, lines, manhole and cleanouts, and the formula and calculations
used to determine the grease trap capacity.
7.
Grease
traps installed by the users.
The food service or other
facility covered by this chapter is responsible for the costs of installing,
operating, cleaning and maintaining its grease trap.
8.
Inspection,
servicing and record keeping.
Inspection, servicing and
maintenance is essential for the efficient operation of grease traps.
Grease traps shall be inspected by the user, serviced and emptied
of accumulated waste contents as is required at or before the trap
capacity reaches seventy-five percent (75%) of its design capacity.
Servicing frequency is site specific and is dependent on the amount
of oil and grease and suspended solids generated at each facility
and the size of the grease trap. In no case shall the frequency of
cleaning be less than once every sixty (60) days, except for interior
or under-sink traps which shall be inspected, cleaned and emptied
of grease at least weekly. The user of a grease trap shall maintain
a log book of all maintenance and cleaning along with evidence, such
as billing and manifests with owner’s signature confirming work
was done, of grease removal and disposal done in accordance with town,
state and federal regulations. The user shall maintain written records
of grease trap maintenance and cleaning for a period of three (3)
years. All such records will be available on-site for inspection by
the town at all times.
9.
Grease
trap pumping and cleaning.
All grease traps shall be
cleaned by a properly licensed cleaning and disposal operation. Cleaning
shall include the initial complete removal of all contents, including
floating materials, wastewater and bottom sludge and scraping solids
from the sides, top and baffles and pipes of the trap. No on-site
aboveground grease storage containers or on-site storage of grease
outside of the approved grease trap shall be allowed under this chapter.
a.
Recycling of gray water.
The return of gray water back
into the grease trap from which the wastes were removed is allowable,
provided that grease and solids are not returned to the trap and provided
the grease hauler has written permission from the facility to return
gray water. The grease hauler shall wait a minimum of twenty (20)
minutes to allow the trap waste to separate in the truck tank before
attempting to reintroduce the gray water to the interceptor. It shall
be the responsibility of each facility to inspect its grease trap
during the pumping procedure to ensure that the grease trap is properly
cleaned out and that all fittings and fixtures inside the trap are
in working order.
b.
Commercial additives, enzymes, emulsifiers and bacteria.
The introduction of bleach, emulsifiers, enzymes or any other chemical
to the grease trap to reduce, thin or break down grease so that it
is flushed or washed out into the public sewer is strictly prohibited.
The addition of live bacteria available from commercial sources is
conditionally permissible, provided the user first obtains written
approval from the public utilities director prior to its use. The
user shall submit MSDS sheets and any other applicable information
concerning the composition, frequency of use and mode of action of
the bacterial additive for the director’s consideration.
10.
Alternative grease removal devices or technologies.
Alternative grease removal devices and technologies such as automatic
grease removal systems shall be subject to written approval by the
public utilities director prior to receiving a permit and installation.
Approval of the device shall be based on demonstrated, proven removal
efficiencies and reliability of operation. The town may approve these
types of devices depending on manufacturers’ specifications
on a case-by-case basis.
11.
Inspection by town.
Grease traps will be inspected by
representatives of the public utilities director or the building inspector
as often as necessary to assure compliance with town ordinances, to
determine if proper cleaning and maintenance schedules are being adhered
to or to perform sampling of facility’s wastewater.
G.
Maintenance
of preliminary treatment and flow equalizing facilities.
Where preliminary treatment or flow equalizing facilities are provided
for any industrial liquid wastes, they shall be maintained continuously
in satisfactory and effective operation by the owner at his expense.
H.
Waste
meters; manholes.
When required by the public utilities
director, the owner of any property serviced by a building sewer carrying
industrial liquid wastes shall install a suitable control manhole
together with such necessary meters and other appurtenances in the
building sewer to facilitate observation, sampling and measurement
of the wastes. Such manhole, when required, shall be accessibly and
safely located, constructed in such a manner as to prevent infiltration
of ground and surface waters and constructed in accordance with plans
approved by the public utilities director. The manhole shall be installed
by the owner at his expense and shall be maintained by him so as to
be safe and accessible at all times.
I.
Methods
of testing; location of test site.
All measurements,
tests and analyses of the characteristics of waters and wastes shall
be determined in accordance with the latest edition of Standard Methods
and shall be determined at the control manhole provided or upon suitable
samples taken at such manhole. The control manhole shall be located
so that sampling of the industrial waste will be performed before
discharge into the public sewer system.
J.
Sampling
and analysis methods.
Sampling shall be carried out by
customarily accepted methods to reflect the effect of constituents
upon the wastewater treatment works and to determine the existence
of hazards to life, limb and property. The particular analyses involved
will determine whether a twenty-four (24) hour composite of all outfalls
of a premises is appropriate or whether a grab sample or samples should
be taken. Normally, but not always, COD, BOD and settleable solids
analyses are obtained from twenty-four (24) hour composites of all
outfalls whereas pHs are determined from periodic grab samples.
K.
Access
for sampling.
The public utilities director shall be
allowed access to the properties of all sewer users to sample, test
and measure all wastewater discharges. Failure to allow such access
may, at the town’s discretion, be the basis for discontinuance
of sewer and/or water service to the property to which access is denied.
(Ordinance 03-15 adopted 2003)
The governing body of the town shall take the necessary steps
to establish an equitable system of user fees. The purpose hereof
is that such individual user shall pay an equitable portion of the
town’s cost of owning the wastewater facilities plus an equitable
portion of the total operation and maintenance costs.
(Ordinance 03-15 adopted 2003)

of any person for a violation shall not excuse or exempt such person
from the payment of any fee due or unpaid at the time of such conviction

cumulative; liens.
All remedies prescribed or liens created
hereunder or under the provisions of the law for collection and enforcement
of the fees shall be cumulative and the use of one or more remedies
