No unauthorized persons (i.e., persons other than personnel
of MTMSA) shall uncover, make any connections with or opening into,
use, alter, or disturb any public sewer or appurtenance thereof without
first obtaining a written permit from the MTMSA Manager.
There shall be three classes of building sewer permits: for
residential service; for commercial service; and for industrial service.
In all cases, the owner or his agent shall make application on a special
form furnished by MTMSA. The permit application shall be supplemented
by any plans, specifications, or other information considered pertinent
in the judgment of MTMSA. A permit and inspection fee for a residential,
commercial and industrial building sewer permit shall be paid to MTMSA
at the time the application is filed. Permit and inspection fees for
sewer permits shall be in such amounts as may be established from
time to time by MTMSA through resolution. No property, building or
structure or use thereof, other than that described in the building
sewer permit, shall at any time be connected with or attached to a
public sewer.
All costs and expenses incidental to the installation, connection,
and maintenance of the building sewer shall be borne by the owner
or user, who shall indemnify MTMSA and Montgomery Township from any
loss or damage that may directly or indirectly be caused by the installation
of the building sewer.
A separate and independent building sewer shall be provided
for every building or any part of any building as may be determined
by MTMSA.
Old building sewers may be used in connection with new buildings
only when they are found, upon examination and test by MTMSA, to meet
all requirements of this Part 1.

A.
FOOD SERVICE FACILITIES
GREASE
GREASE INTERCEPTOR
OIL/WATER SEPARATOR
Definitions. As used in this section, the following terms shall have
the meanings indicated:
Those establishments 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), grilling, sauteing,
rotisserie cooking, broiling (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. These facilities include restaurants, cafeterias, hotels,
motels, hospitals, nursing homes, schools, grocery stores, churches,
camps, caterers, manufacturing plants, or any other industrial or
commercial establishments which discharge, or are likely to discharge,
grease into the public sewer system.
Material composed primarily of fats, oil, and grease from
animal or vegetable sources. The term "fats, oil and grease" shall
be deemed as grease by definition. Grease does not include petroleum-based
products.
A device for separating and retaining waterborne greases
and grease complexes prior to the wastewater exiting the interceptor
and entering the public sewer system. These devices also serve to
collect settlable solids, generated by and from food preparation activities,
prior to the wastewater exiting the interceptor and entering the public
sewer system.
A device that is specifically designed and manufactured to
separate oil from water and permits the oil to be collected and removed
on a regular basis so as to prevent it from being discharged into
the public sewer system.
B.
Control plan for grease and food waste.
(1)
Any person who constructs, renovates or expands a food service facility
shall be required to submit to MTMSA a grease and food waste control
plan that will effectively control the discharge of undesirable materials
into the public sewer system.
(2)
Any owner of an existing food service facility shall also be required
to submit a grease and food waste control plan that will effectively
control the discharge of undesirable materials into the public sewer
system.
C.
Grease interceptor installation, connection and location requirements.
(1)
Installation requirements. All owners of existing, proposed or newly
renovated or expanded food service facilities within the MTMSA wastewater
service area shall be required to install, at the owner's expense
an approved, properly operated and maintained grease interceptor.
(2)
Sanitary sewer flows. Sanitary sewer flows from toilets, urinals,
lavatories, etc., shall not be discharged into the grease interceptor.
These flows shall be conveyed separately to the sanitary sewer service
lateral.
(3)
Floor drains. Only floor drains which discharge or have the potential
to discharge grease shall be connected to a grease interceptor.
(4)
Garbage grinders/disposers. Solid food waste products shall be disposed
of through normal solid waste/garbage disposal means, and not the
sanitary sewer system.
(5)
Dishwashers. Commercial dishwashers must be connected to the grease
interceptor. Dishwashers discharge soap and hot water which can melt
grease and allow it to pass through an undersized grease interceptor.
Interceptors must be sized accordingly to allow enough detention time
to allow water to cool and grease to solidify and float to the top
of the interceptor.
(6)
Location. The grease interceptor shall be installed outside the building
upstream from the sanitary sewer service lateral connection unless
MTMSA allows an interior installation. This will allow easy access
for inspection, cleaning and removal of the intercepted grease at
any time. A grease interceptor may not be installed inside any part
of a building without written approval by MTMSA.
D.
Design criteria.
(1)
Construction. Grease interceptors shall be constructed in accordance
with the standards of the MTMSA and shall have a minimum of two compartments
with fittings designed for grease retention. All grease-removal devices
or technologies shall be subject to the written approval of MTMSA.
Such approval shall be based on demonstrated removal efficiencies
of the proposed technology.
(2)
Access. Access to grease interceptors shall be available at all times,
to allow for their maintenance and inspection. Access to grease traps
shall be provided by two manholes (one on each compartment) terminating
at finished grade with cast-iron frame and cover.
(3)
Load-bearing capacity. In areas where additional weight loads may
exist, the grease interceptor shall be designed to have adequate load-bearing
capacity.
(4)
Inlet and outlet piping. Wastewater discharging to a grease interceptor
shall enter only through the inlet pipe of the interceptor. Each grease
interceptor shall have only one inlet and one outlet pipe.
(5)
Grease trap sizing. The required size of the grease interceptor shall
be calculated using the EPA-2 model. All grease interceptors shall
have a capacity of not less than 1,000 gallons nor exceed a capacity
of 3,000 gallons. If the calculated required capacity exceeds 3,000
gallon, multiple units plumbed in series shall be installed.
E.
Grease interceptor cleaning/maintenance.
(1)
Cleaning/pumping. The owner of a food service facility shall,. at
such owner's expense, maintain and keep in good repair all grease
interceptors to assure the proper operation and efficiency thereof.
Cleaning of grease interceptors shall include the complete removal
of all contents, including floating materials, wastewater, and bottom
sludge and solids. This work shall be performed by a qualified and
licensed hauler. Decanting or discharging of removed waste back into
the grease interceptor from which it was removed or any other grease
trap, for the purpose of reducing the volume to be disposed, is prohibited.
Cleaning shall also include a thorough inspection of the interceptor
and its components. Any needed repairs shall be noted, and repairs
shall be made at the owner's expense.
(2)
Cleaning/pumping frequency. The grease interceptor must be cleaned/pumped
out completely a minimum of once every four months, or more frequently
as determined by MTMSA, as needed to prevent carryover of grease into
the MTMSA sewer system.
(3)
Disposal. All materials removed from each grease interceptor must
be disposed of at a facility approved to receive such waste in accordance
with the provisions of this program. In no way shall the pumpage be
returned to any private or public portion of the public sewer system.
All pumpage from grease interceptors must be tracked by a manifest,
which confirms pumping, hauling and disposal of the waste. The owner
of the food service facility must obtain and retain a copy of the
original manifest from the hauler.
(4)
Maintenance log. A grease interceptor cleaning/maintenance log, indicating
each cleaning/pumping for the previous 24 months, shall be maintained
for each food service facility by the owner thereof. This log shall
include the date, time, amount pumped, hauler and disposal site and
shall be kept in a conspicuous location for inspection. Said log shall
be made available to MTMSA or its representative, upon request.
(5)
Submittal of records.
(a)
Each owner of a food service facility shall submit all cleaning
and maintenance records to MTMSA. The maintenance records shall include
the following information:
[1]
Facility name, address, contact person and phone number;
[2]
Company name, address, phone number and contact name of person
responsible for performing the maintenance, cleaning, pumping or repair
of grease interceptor;
[3]
Types of maintenance performed;
[4]
Dates maintenance was performed;
[5]
Date of next scheduled maintenance; and
[6]
Copies of manifests.

Montgomery Township Municipal Sewer Authority
| |
|
1001 Stump Road
| |
|
Montgomeryville, PA 18936
|
(6)
The MTMSA will perform periodic inspections of food service facilities
and shall notify the owner thereof any additional required maintenance
or repairs. Upon written notification by the MTMSA, the owner shall
be required to perform the specified maintenance within 14 calendar
days. Upon inspection by the MTMSA, the owner may be required to install,
at his expense, additional controls to provide a complete system which
prevents discharges of undesirable materials into the public sewer
system.
F.
Additives. Any biological additive(s) placed into the grease interceptor
or building discharge line, including but not limited to enzymes,
commercially available bacteria, or other additives designed to absorb,
purge, consume, treat or otherwise eliminate grease, shall require
written approval by the MTMSA prior to use. The use of such additives
shall in no way be considered as a substitution for the maintenance
procedures and/or cleaning procedures required herein.
G.
Chemical treatment. Chemical treatments such as drain cleaners, acid
or other chemical solvents designed to dissolve or remove grease shall
not be allowed to enter the grease interceptor.
H.
Sand, soil and oil separators. All owners of car washes, truck washes,
garages, service stations, car and truck maintenance facilities, fabricators,
utility equipment shops and other facilities (as determined by the
MTMSA) that have sources of sand, soil and oil shall install effective
sand, soil and oil traps, interceptors and/or oil/water separators.
These systems shall be sized to effectively remove sand, soil and
oil at the expected flow rates. These systems shall be designed in
accordance with the criteria established within the latest edition
of the International Plumbing Code. These systems shall be, at the
owner's expense, cleaned or pumped on a regular basis to prevent impact
upon the MTMSA sewer system. Users whose systems are deemed to be
ineffective by the MTMSA shall be asked to change the cleaning frequency
and/or to increase the size of the system. Owners of washing facilities
will be required to prevent the inflow of detergents and rainwater
into the MTMSA sewer system. Oil/water separator installations shall
be required at facilities that accumulate petroleum oils and greases.
I.
Laundries. Owners of commercial laundries shall equip them with an
interceptor with a wire basket or similar device, removable for cleaning,
that prevents passage into the MTMSA sewer system of solids 1/2 inch
or larger in size, such as rags, strings, buttons, or other solids
detrimental to said system.
J.
Bottling establishments. Bottling plants shall discharge wastewater
into an interceptor that will provide for the separation of broken
glass or other solids before discharging into the MTMSA sewer system.
K.
Permit requirement. Every person who is required to install a grease
interceptor or a sand, soil and oil separator shall apply for and
be issued a permit setting forth required specifications for said
interceptor and separator and cleaning, maintenance, disposal and
reporting requirements.
L.
Cost reimbursement. If MTMSA is required to repair and/or clean out
its sewer lines as a result of a stoppage resulting from a poorly
maintained grease interceptor, and/or sand, soil and oil separator,
the owner thereof shall be required to refund the labor, equipment,
materials and overhead costs incurred by MTMSA and any fines incurred
by MTMSA due to any sanitary sewer overflow caused by the stoppage.
Additionally, the owner shall also pay the reasonable costs and fees
incurred by the MTMSA by having to engage the services of its consulting
engineers and solicitor in connection with the administration of the
requirements of this section.
M.
Inspection. MTMSA or its representatives shall have the right at
reasonable times to inspect any grease interceptor or sand, soil and
oil separator.
N.
Alteration of control methods. MTMSA reserves the right to request
additional control measures if existing control equipment is shown
to be insufficient to protect the MTMSA sewer system from interference
due to the discharge of grease, sand, soil, oil or any other undesirable
materials.
Whenever possible, the building sewer shall be brought to the
building at an elevation below the basement floor. In all buildings
in which any building drain is too low to permit gravity flow to the
public sewer, sanitary sewage carried by such building drain shall
be lifted by a method approved by MTMSA and discharged to the building
sewer.
No person shall make connection of sump pumps, roof downspouts,
foundation drains, areaway drains, or other sources of surface runoff
or groundwater to a building sewer or building drain which in turn
is connected directly or indirectly to a POTW unless such connection
is approved in writing by MTMSA for purposes of disposal of polluted
surface drainage.
The connection of the building sewer to the lateral installed
on the POTW collection system shall conform to the requirements of
the building and plumbing codes or other applicable standards set
forth in MTMSA's Standard Specifications for the Construction of Sanitary
Sewers, Force Mains, Pump Stations, and Wastewater Treatment Plants,
latest edition. All such connections shall be made gastight and watertight,
and verified by proper testing. Any deviation from the prescribed
procedures and materials must be approved by MTMSA before installation.
The applicant for the building sewer permit shall notify the
MTMSA Manager when the building sewer is ready for inspection and
connection to the POTW. In the event that the applicant installs the
lateral, he shall notify the MTMSA Manager when the lateral is ready
for inspection before the trench is backfilled. The connection to
the public sewer and testing shall be made under the supervision of
the MTMSA Manager or his representative.
All safety measures during construction or installation of sewer
facilities by an owner shall be the sole responsibility of the owner
and his agents and contractors and shall conform to all federal, state
and local laws and regulations. All excavations for building sewer
installation shall be adequately guarded with barricades and lights,
so as to protect the public from hazard. Streets, sidewalks, parkways,
and other public property disturbed in the course of work shall be
restored in a manner satisfactory to MTMSA and Montgomery Township.
No excavation, construction, or connection work shall be commenced
within the Montgomery Township or MTMSA right-of-way until the owner,
his agents and/or independent contractor shall comply with the regulations
and requirements of the MTMSA, including but not limited to: obtaining
necessary permit or permits applicable to said work, paying all required
tapping fees and connection fees, entering into a tapping fee and
development agreement which shall set forth terms relating but not
limited to indemnification of MTMSA, insurance coverage, and the applicant's
being responsible for any damages to person or property in connection
with any such work.
The term "owner," as used herein, shall be deemed to include
the owner or owners in fee simple, lessees of the premises, occupiers
of the premises, users, and all other parties having a use or interest
in the premises and occupying the same with or without the consent
and permission of the owner of the fee title.
Sanitary sewers installed with unused points of connection for
building sewers shall have said points of connection capped for watertight
integrity prior to connection of the building sewer. The method of
capping shall be one approved by the MTMSA Manager.
