All food service establishments shall be required to install a grease trap unless an exemption is granted pursuant to this Part 1. All other residential, commercial and/or industrial establishments shall be required to install a grease trap/interceptor when, in the opinion of the Borough Plumbing Subcode Official, grease, flammable waste, oil and sand interceptors or oil reclaimers are necessary due to the type of activity/use of the property. All grease traps shall be maintained at the expense of the owner and kept in a continuously efficient operating condition. Grease, oil and sand separators shall not be required for residential-type uses unless such use services more than five families or 15 individual residents. The following regulations and requirements shall apply to the requirement of utilizing grease traps:
A. 
Grease and oil interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be watertight and substantially constructed and equipped with readily removable access covers. The design and pertinent data shall be submitted to the Borough Plumbing Subcode Official for review and approval prior to construction or installation. Separators must be constructed entirely on the property of the owner.
B. 
Restaurants, cafeterias, institutional kitchens and other installations discharging grease shall use a grease trap. A garbage grinder shall not be used when a grease trap is required.
C. 
The grease trap shall be installed in a separate line serving that part of the plumbing system into which the grease will be discharged. The grease trap shall be located close to the source of wastewater, where the wastewater is still hot, to facilitate separation. Grease traps shall be located, designed and constructed in a manner that will permit easy access and cleaning.
D. 
Grease traps shall have the grease retention capacity as indicated in the following table for the flow-through rates indicated:

Grease traps shall be equipped with devices to control the rate of water flow so that the water flow does not exceed the rated flow.
F. 
In all cases, grease traps shall conform to the Plumbing and Drainage Institute G101-8 Standards.
G. 
Oil separators shall be designed as provided below.
(1) 
Overall requirements. Oil separators shall have a depth of not less than two feet (610 mm) below the invert of the discharge drain. The outlet opening of the interceptor shall have not less than an eighteen-inch (457 mm) water seal.
(2) 
Garages and service stations. Where automobiles are serviced, greased, repaired, washed or where gasoline is dispensed, interceptors shall have a minimum capacity of six cubic feet (0.168 cubic meters) for the first 100 square feet (9.3 square meters) of area to be drained, plus one cubic foot (0.028 cubic meters) for each additional 100 square feet (9.3 square meters) of area to be drained, plus one cubic foot (0.028 cubic meters) for each additional 100 square feet (9.3 square meters) of area to be drained into the interceptor. Parking garages in which servicing, repairing or washing is not done, and in which gasoline is not dispensed, shall not require a separator. Areas of commercial garages used only for storage of automobiles are not required to be drained through an interceptor.
H. 
Sand interceptors for commercial establishments. Sand and similar interceptors for heavy solids shall be designed and located so as to be readily accessible for cleaning and shall have a water seal of not less than six inches (152 mm).
I. 
Laundries. Commercial laundries shall be equipped with a solid interceptor with a wire basket or similar device, removable for cleaning, that will prevent passage into the drainage system of solids 1/2 inch (13 mm) or larger in size, string, rags, buttons or other materials detrimental to the public sewerage system.
J. 
Bottling establishments. Bottling plants shall discharge their process wastes into an interceptor, which will provide for the separation of broken glass or other solids before discharging waste into the drainage system.
K. 
Venting of interceptors and separators. Interceptors and separators shall be designed so as not to become airbound, if tight covers are used. Each interceptor or separator shall be vented when subject to loss of trap seal.
L. 
Accessibility and maintenance of interceptors and separators. Each interceptor and separator shall be installed so as to be readily accessible for service and maintenance. Interceptors and separators shall be maintained by periodic removal of accumulated grease, scum, oil or other floating substances and solids deposited in the interceptor or separator.
M. 
All grease, oil and sand interceptors shall be maintained by the owner, at his expense, in continuous, efficient operation at all times.
N. 
It is the responsibility of the establishment owner, lessee or assignee to carry out all proceedings necessary to have any and all grease interceptors opened and ready for inspection and to see that the equipment is put back in proper operation after the inspection. All inspections will be conducted by the Plumbing Subcode Official.
O. 
Forms for periodic inspections will be furnished by the owner, lessee or assignee and posted as close as possible to the interceptor to which it applies. The form shall be protected from soiling. In those instances where the interceptor is chemically treated, the method and chemical of such treatment shall be approved by the Plumbing Subcode Official. Any proposed chemical changes shall be furnished to the Plumbing Subcode Official for approval. Copies of maintenance and removal records shall be provided to the Plumbing Subcode Official within seven days of such occurrence.
