The title of this article is "Fats, Oil and Grease (FOG) Abatement.'
A.
The discharge of fats, oil, grease, sand, grit or other harmful materials
into the public sewer system poses a threat to the health, welfare
and safety of the residents of the Town of Penfield by reducing system
reliability; and requires additional maintenance efforts which increase
cost. The Town Board, as Commissioners of the Town of Penfield sanitary
sewer district(s), desires to reduce discharge of these substances
to the maximum extent practical and control their introduction to
the district's facilities.
B.
This article provides rules and regulations which set acceptable
discharge limits of FOG to the public sewer system and specifies minimum
controls for the separation and removal of these materials from the
wastewater stream.
As used in this article, the following terms shall have the
meanings indicated:
That individual designated by the Sewer District Commissioners
or the Superintendent to check and verify compliance with this article
or conduct inspections of facilities or GT.
The measure of the amount of oxygen required to oxidize and
stabilize organic material in wastewater.
Includes each plumbing fixture, appliance, apparatus, or
other equipment required to be connected to or discharging into a
grease trap (GT) or interceptor.
The measurement of fats, oils and grease present, measured
in mg/l.
A one-liter sample drawn from the effluent. The amount of
FOG present, in mg/l, shall be determined by using the hexane method.
An appropriately sized receptacle utilized by commercial
or industrial sewer users to intercept, separate and collect fats,
oils, grease or other organic waste commonly found in the handling,
preparation or serving food, approved by the ADR.
Accumulated fats, oils, grease or other organic waste in
a GT, which on some regular basis, determined by separation effectiveness
and material accumulation, is removed for proper disposal.

suspended waste materials, including but not limited to septic and
wastes from grease traps and grit traps.
A person responsible for conducting, supervising, managing
or representing the business activities of a sewer user or transporter.

users are to make their connection to the public sewer system to facilitate
observation, sampling and measurement of the wastewater discharge.

from discharge emanating from floors, floor drains or pits commonly
found in facilitates involved in repair, maintenance or washing of
automobiles, machinery or equipment maintenance.

receiving works of either Monroe County Pure Waters or adjacent municipalities
under contract for such conveyance.
A receptacle used to separate sand, grit or other particulate

(5)
Separate drain lines serve all of the kitchen fixtures. Toilets,
urinals, and other sanitary fixtures shall not drain through the GT.

All waste shall enter the GT through the inlet pipe only.
(8)
In vehicular traffic areas, the GT shall be designed to have a minimum

(10)
Each GT shall serve only one facility.
A.
Any user making application for a building permit to renovate, modify
or upgrade its restaurant or food service facility shall be required
to upgrade its FOG compliance equipment.
(1)
Any new commercial kitchen or modification to an existing commercial
kitchen without appropriate GT provisions shall be required to provide
an appropriately sized GT, in compliance with the sizing rules and
regulations contained herein.
(2)
Any modifications to an existing kitchen having an existing GT, or
modifications to an existing restaurant having an existing kitchen
with a GT installation, shall demonstrate that the existing GT is
appropriately sized, in good working order and functioning properly.
B.
In either of these cases, the user or permittee shall be required
to install a test port on the discharge side of the GT for measurement
of FOG concentrations.
A.
Any GT with a surface FOG cake of six inches in thickness or greater
or a bottom sediment layer of greater than 12 inches is considered
to be out of compliance and shall be immediately cleaned. This requirement
shall be checked by stick test.
B.
All users shall service their GT by pumping, cleaning and backwash
as often as necessary so as to keep the GT in compliance. Such service
shall include complete removal of GT contents, in lieu of skimming
the top of the grease layer only. Thorough cleaning of the GT shall
include the removal of grease and scum from the inner walls and baffles
and complete removal of sediment from the bottom of the GT.
C.
The user/manager of a restaurant facility shall designate an individual/employee
who shall be responsible for checking the function of the GT. This
person will initially establish the regularity of GT maintenance.
The user/manager is responsible for keeping all GT maintenance records
which demonstrate regular pumping and cleaning of the GT.
D.
These records shall indicate dates pumped, amounts pumped, the hauler,
and destination of pumped materials. These records shall be available
for review by the ADR upon inspection. Missing, incomplete or no records
constitute a violation of this article.
Pursuant to this article, the ADR is granted the right to enter
any business, without announcement or appointment, for the express
purpose of reviewing records pertaining to the user's GT maintenance,
to inspect equipment or sample any discharges emanating from the establishment.

C.
Users whose GT is found out of compliance with this article shall
be given written notice by the ADR to correct the violation within
two weeks. If the violation is not corrected by the user within two
weeks of written notice or if this is a repeat violation, the user
may be referred for enforcement action.
D.
No person shall discharge to the public sewer system any nondomestic
waste from holding tanks, sludge or skimmings from the cleaning or
pumping of GT or oil water separator and grease traps to any of the
district(s)-owned collection points.
To ensure that the GT remains in good working order, there are
several best management practices (BMP) that should be followed to
reduce maintenance costs and avoid enforcement.
A.
Prevent the utilization of disposal for food waste that is high in
fat content. These products can be disposed of in approved garbage
bins.
B.
Recycle used cooking oils when possible or place them safely in the
trash.
C.
The total contents of the GT shall be removed on a regular basis
or as needed to prevent problems in the system.
D.
Repairs shall be made promptly.
E.
Keep GT accessible to allow for periodic inspection and maintenance.
F.
It is recommended that a dish-washing machine not be the last fixture
on the line which is connected to the GT.
G.
Waste grease from fryers is considered recyclable oil and grease.
All users shall have waste grease containers to store recyclable oil
and grease. Users are encouraged to contract with licensed renderers
to remove the collected waste oil and grease and haul it to the renderer's
processing plant.
H.
Users are encouraged to become familiar with their GT function, and
promote the above practices within their organization.
Repeat violations may be cause for revocation of special use
permits for operation, monetary penalties or both.
