[Amended 3-18-2013 by Ord. No. 520]
A. Definitions. As used in this
section, the following terms shall have the meanings indicated:
CONTINUOUS DISCHARGE
The use of any amenity, as described under Subsection
B, which operates for seven continuous days. This category will include seasonal facilities which qualify for seven continuous days of operation. Furthermore, this category includes facilities which operate less than 24 hours per day and operate for at least one day during the weekend.
FIXTURE
Includes each plumbing fixture, appliance, apparatus or other
equipment required to be connected to or discharged into a grease
trap by any provision of this section.
GREASE INTERCEPTOR
An interceptor of at least 750 gallons' (2,839 liters') capacity
to serve one or more fixtures (as defined herein) and which shall
be remotely located.
GREASE TRAP
A device designed to retain grease from one to a maximum
of four fixtures.
INTERMITTENT DISCHARGE
The use of any amenity as described under Subsection
B which operates for five days or less.
B. Installation. When in the judgment
of the Township Code Enforcement Officer or his/her assigned representative
(the "Code Officer"), waste pretreatment is required at a facility
within the Township, a grease trap, complying with the provisions
of this section, shall be installed in the waste line leading from
sinks, drains and other fixtures or equipment in facilities such as
restaurants, cafes, lunch counters, cafeterias, bars and clubs, hotels,
hospitals, sanitariums, factory or school kitchens, or other establishments
where grease may be introduced into the drainage or sewage system
in quantities that can effect line stoppage or hinder sewage treatment
or private sewage disposal. The following condition shall be in effect:
(1) No grease trap shall be installed
which has an approved rate of flow of more than 55 gallons per minute
(3.5 l/s), nor less than instantaneous flow of 20 gallons per minute
(1.3 l/s), without the prior written approval of the Code Officer.
(2) Each plumbing fixture or
piece of equipment connected to a grease trap shall contain an approved
vented flow control installed in a readily accessible and visible
location. Flow-control devices shall be designed that the flow through
such device or devices shall at no time be greater than the rated
capacity of the grease trap. No flow-control device having adjustable
or removable parts shall be approved. The vented flow-control device
shall be located such that no system vent shall be between the flow
control and the grease trap inlet. The vent or air inlet of the flow-control
device shall connect with the sanitary drainage vent system as elsewhere
required by acceptable industry standards or shall terminate through
the roof of the building and shall not terminate to the free atmosphere
inside the building. Exception: listed grease traps with approved-type
flow controls or restricting devices may be installed in an accessible
location in accordance with the manufacturer's instructions.
(3) Each grease trap required by this section shall have an approved rate of flow which is not less than that given in the table in §
288-44D(2)(a)[1] for the total number of connected fixtures. The total capacity in gallons (G) of fixtures discharging into any such grease trap shall not exceed 2 1/2 times the certified gpm (l/s) flow rate of the grease trap as per that table. Not more than four separate fixtures shall be connected to or discharged into any one grease trap.
(4) Each fixture discharging
into a grease trap shall be individually trapped and vented in an
approved manner.
(5) Grease traps shall be maintained
in efficient operating condition by periodic removal of the accumulated
grease, fat or oil. No such collected grease, fat or oil shall be
introduced into any drainage piping or public or private sewer.
(6) No water-jacketed grease
trap or grease interceptor shall be approved or installed.
(7) Required grease interceptors,
installed outdoors, shall comply with the provisions of in-ground
grease interceptors.
(8) Grease traps shall not be
installed in food preparation areas of kitchens.
(9) Grease interceptors shall
be installed outside of the kitchen area in a location affording ease
of maintenance and servicing.
(10) Unless specifically required
or permitted by the Code Officer, no food waste disposal unit or dishwasher
shall be connected to or discharge into any grease trap.
(11) A grease trap is not required
for individual dwelling units or for any private living quarters.
C. Limitations. The owners/operators
shall prohibit the entrance into their sewage system and subsequently
to the City of Reading's sewage treatment plant of sewage containing
more than 100 parts per million by weight of fats, oil or grease,
as measured by Method 1664, Revision A: n-hexane extractable material
(HEM; oil and grease) or more than 25 parts per million by weight
of fat, oil or grease as measured by silica-gel-treated n-hexane extractable
material (SGT-HEM; nonpolar material) by extraction and gravimetry.
D. Interceptor sizing.
(1) Indoor grease trap/grease
interceptor sizing. An indoor grease trap/interceptor can be used
for capturing grease sediments connected to four fixtures or fewer.
This is a mandatory measure for preventing the discharge of fats,
oil or grease into the sanitary sewer system. A grease interceptor
shall be sized based on a flow rate in gallons per minute (GPM). The
owner/operator shall provide necessary calculations completed by a
licensed professional engineer when determining and selecting the
size of the grease interceptor. For basic guidance, the following
steps should be used to determine the appropriate size for new indoor
grease trap/interceptors:
(a) Step 1: Determine
the cubic size of connected fixture(s) or sink(s). To determine the
sink volume, multiply the length, width and depth (L x W x D) of the
sink by the number of sinks. All measurements must be in inches and
not feet.
(b) Step 2: Convert
the cubic inches into gallons using the following conversion: 1 gallon
= 231 cubic inches.
(c) Step 3: Estimate
the capacity of the sink(s) measured in Step 1. Usually, 75% of the
sink(s) will be filled with water; the remaining 25% will be dishes,
utensils, etc. Multiply that factor as a percentage (e.g., 75% = 0.75,
25% = 0.25, etc.) by the number of gallons calculated in Step 2. This
will also serve as the flow rate discharging to the grease trap.
(d) Step 4: Select
a grease trap/interceptor that is the next size higher than the calculated
flow rate. For example: if the calculated flow rate is 78 GPM, available
interceptors are sized for 70 and 80 GPM; the most-appropriate choice
is the latter, an 80-GPM device.
(2) Outdoor grease trap/grease
interceptor sizing. Outdoor in-ground grease interceptors are mandatory
for restaurants and other food service facilities that produce large
amounts of fat, oil and grease during food preparation. There are
two methods when sizing an outdoor grease interceptor. The first is
based on criteria established by proper wastewater analyses defining
the content of fat, oil and grease. The owner/operator shall provide
the necessary calculations completed by a licensed professional engineer
when determining and selecting the size of a grease interceptor to
meet the needs based on this method. The second is the application
of the Manning Formula, which is described as follows:
(a) The Manning Formula: Interceptor Size (in gallons)
= Flow Rate (GPM)/sink or fixture
multiplied by the sum of fixture Ratings plus the Discharge rate
from any mechanical washers (i.e., dishwashers, glass washers, laundry
machines, etc.) multiplied by a twenty-four-minute retention Time.
The summarized version being: I = [(Fr) x (R) + (D)] x (T)
|
[1] Flow rate, measured
in GPM, is determined based on the slope, pipe texture, and pipe diameter.

[2] Fixture ratings of
grease-laden waste streams are predetermined values based on specific
kitchen drainage points, such as sinks, wash basins, and floor drains.
Essentially, these values represent factors by which the flow rate
of a drainage pipe shall be used to determine the potential rate of
water movement out of the fixture. Apply as demonstrated in the examples
below.

[3] The discharge rate
from dishwashers, laundry machines, glass washers, etc., must be added
to the Manning Formula calculation because of their potential for
introducing large quantities of water down the drain in a short amount
of time. The user's manual for these appliances should indicate the
manufacturer's discharge rate in GPMs; contact the manufacturer to
learn about specific equipment discharge.
[4] The twenty-four-minute
retention time is a precalculated amount of time that the licensed
professional engineer has determined to be necessary for grease to
separate from water. The licensed professional engineer shall demonstrate
by calculation that the proposed design of the grease trap based on
the capacity of the holding tank (grease separator) in relation to
the influent shall maintain fat, oil and grease particulate content
in the effluent at less than 100 parts per million (100 PPM).
E. Reporting. Owners and operators
of gas stations, restaurants and other facilities required by this
section to have grease and/or oil traps and/or interceptors shall
be subject to biannual inspection by the Code Officer. Owners/operators
shall submit certified quarterly reports (March 31, June 30, September
30, December 31) each year in a form prescribed by the Code Officer,
certifying that the grease and/or oil traps and/or interceptors have
been cleaned. The report provided shall manifest the name of the person
or contractor responsible for the work, the date of cleaning and the
location where the material is being disposed. The report hereafter
shall be referred to as the "quarterly report."
F. Inspection.
(1) The Code Officer shall, biannually,
inspect all such facilities' grease trap/interceptors and review the
owner/operator's quarterly reports.
(2) All grease trap/interceptors
must be approved by the Code Officer and shall be located such that
they are readily accessible for cleaning and inspection.
(3) If any inspection or quarterly report indicates that prohibited discharges have occurred (§
288-41) or that the grease trap/interceptor is substandard in performance, the Code Officer may, in addition to any other remedies, conduct additional inspections and/or require additional reports or tests as needed to correct the deficiencies.
(4) Costs of all reports and
any necessary additional inspections or tests shall be borne by the
owner/operator of the facility.
G. Fees. The Township's annual fees, adopted by resolution, shall include two inspections per annum. The owner/operator shall pay the annual fees, adopted by resolution, to the Township within 30 days from the date of the notice that the same are due. If the fees are not paid within said thirty-day time period, the amount due shall be increased to be two times the original amount. If the same remains unpaid after 90 days from the date of the notice, the same shall constitute a violation of this section for which the penalties set forth in Subsection
I below shall be enforced. The two inspections shall be considered regular maintenance inspections and shall be conducted on the assumption that the grease trap system is functioning to industry standards. In the event the Code Officer reports a malfunctioning grease trap system at said inspections, the owner/operator of the grease trap system must remedy this malfunction as directed by the Code Officer. Additional inspection charges may be assessed if any additional site inspections are deemed necessary as a result of a failed inspection. Such inspection charges shall be assessed as set forth by the Township in the resolution adopting the fee schedule.
H. Failure to report. The owner/operator
of a facility equipped with a grease trap system shall provide a quarterly
report as set forth hereinabove. Failure to provide any required quarterly
report within 15 days from its due date shall constitute a violation
of this section of the Township Code, and the owner/operator shall
be assessed a fine of $250 for the first such offense and fines of
$500 for each subsequent offense.
I. Violations. Except as otherwise
specifically set forth herein, any person found to be violating the
terms of this section of the Township Code shall be subject to a fine
not to exceed $1,000. Each day of noncompliance with this section
of the Township Code shall be deemed to be a separate violation, and
a fine not to exceed $1,000 may be issued for each day of the noncompliance.
If a judgment is entered against any person for violating this section
of the Township Code, and said person defaults in the payment of the
fine or penalty imposed by said judgment, said person may be sentenced
and committed to the County of Berks prison for a period not to exceed
30 days.
The Township may establish fees to be charged
to the users of facilities requiring oil interceptors and/or grease
traps to cover the administrative and inspection expenses incurred
in the administration and/or enforcement of the provisions of this
Part 5.
Any person, partnership, corporation or entity
who or which has violated or permitted the violation of any provisions
of this Part 5 shall, upon being found liable therefor in a civil
enforcement proceeding commenced by the Township, pay a fine/judgment
of not more than $600 per violation plus all court costs, including
reasonable attorneys' fees incurred by the Township as a result thereof.
Each day that a violation continues shall constitute a separate violation.
All fines, judgments, costs and reasonable attorneys' fees imposed
shall be enforceable and recoverable in the manner at the time provided
by applicable law and shall be payable to the Township. In addition,
the Township may compel the violator to cease using the sewer system
until the condition causing the violation is corrected. The Township
may compel violators to cease using the sewer system by directing
the Authority to terminate water service (on written notice with a
ten-day right to cure), with all usual and customary Authority charges
for service termination and service reinstatement to be the responsibility
of the violator.
The remedies provided herein are not intended
to be exclusive. The Township reserves the right to take any and all
action permitted by law against a person violating this Part 5.
