[Amended 3-4-1997]
A.
Grease interceptors required.
(1)
Grease interceptors shall be provided in the following
establishments where food is prepared or dispensed: restaurants, cafes,
lunch counters, cafeterias, bars and clubs, hotels, bed-and-breakfasts,
hospitals, sanitariums, factories, school kitchens, commercial kitchens
and nursing homes.
(2)
The Wastewater Superintendent may authorize annual
waivers in those cases where one of the above commercial establishments
is determined not to be a grease generator. Any establishment that
generates wastewater, or other waste to enter the public sewer, which
contains less than 100 parts per million, by weight, of fat, oil or
grease shall be considered not to be a grease generator. In reaching
his determination, the Wastewater Superintendent may require a test.
Testing fees, if necessary, shall be paid by the applicant. If inspection
of a sewer service indicates grease is entering the system from a
property that has previously obtained a waiver, the Superintendent
may revoke the waiver and require that a grease interceptor be installed.
[Amended 10-21-2008 by Ord. No. 2008-04]
(3)
A grease interceptor is not required for individual
dwelling units or for any private living quarters. Establishments
which are not on the public sewer system are exempt from the requirements
of this chapter.
B.
Oil and sand interceptors required. Oil and sand interceptors
shall be provided when, in the opinion of the Superintendent, they
are necessary for the proper handling of liquid wastes containing
any flammable wastes, sand or other harmful ingredients, except that
such interceptors shall not be required for private living quarters
or dwelling units.
C.
Construction and design of interceptors. All grease
interceptors shall be of a design conforming to Plumbing and Drainage
Institute Standard PDI-G101, December 1985 Edition.[1] Sand and oil interceptors, when in the opinion of the
Superintendent they are necessary, shall conform to the same standards
as grease interceptors. Grease and oil interceptors shall be constructed
of impervious materials capable of withstanding abrupt and extreme
changes in temperature. They shall be of substantial construction,
watertight and equipped with easily removable covers which, when bolted
in place, shall be gastight and watertight. The Superintendent shall
review and approve all sizing requirements prior to application for
the installation permit.
[Amended 10-21-2008 by Ord. No. 2008-04]

Editor's Note: A copy of Standard PDI-G101
is on file at the Town Clerk's office.
D.
Permit required for installation. A permit for installation
of an interceptor shall be obtained from the local plumbing inspector.
E.
Location. Each interceptor and grease trap cleaning
record shall be so located as to be readily and easily accessible
for cleaning and inspection at all times. Grease trap cleaning records
shall be displayed proximal to the location of the grease interceptor.
Grease interceptors shall be of the internal type.
[Amended 10-21-2008 by Ord. No. 2008-04]
F.
Installation and maintenance.
[Amended 10-21-2008 by Ord. No. 2008-04]
(1)
All establishments which are required to install grease
interceptors must have the same installed no later than August 1,
1997.
(2)
Installation and maintenance of any interceptor shall
comply with the Plumbing and Drainage Institute Standard PDI-G101,[2] except that accumulated grease shall be removed as needed
and at the minimum of one time every two weeks during July, August
and September and one time every four weeks at other times of the
year. If inspection indicates minimum cleaning requirements are not
adequate, additional cleanings may be required. Owners of properties
in which grease interceptors are installed must, on grease trap cleaning
records provided by the Town of Bar Harbor, maintain a record of the
dates that such interceptors are cleaned. These records remain the
property of the Town of Bar Harbor and are the only recognized proof
of cleaning. Seasonal businesses are exempt from inspection and cleaning
requirements during the times of year when they are closed.

G.
Inspection and violations. In the application for the installation of an interceptor, the owner or tenant of the premises shall grant to the Town permission to conduct unannounced inspections of such interceptor during normal business hours, which inspections shall not unreasonably interfere with normal operations of the business. Should an inspection show a violation of this § 165-42, the owner and/or tenant of the premises will be advised as to the requirements of this section. Should a second inspection reveal a violation of § 165-42, a written warning shall be issued describing the requirements of this section. In the event that a third violation occurs, the highest dollar value of the following will be charged to the owner, tenant and/or occupant of the premises for each violation: a minimum surcharge of $200 or a ten-percent surcharge to the premises' sewer bill for the current quarter. If further violations continue, these may result in the prosecution of the owner, tenant and/or occupant of the premises pursuant to § 165-50 of this chapter.
[Amended 10-21-2008 by Ord. No. 2008-04]
Where preliminary treatment facilities are installed
they shall be maintained by the owner, at his expense, in continuously
efficient operation at all times and made available to the Superintendent
for periodic inspection.
A.
The admission into the public sewers of any waters or wastes having a five-day biochemical oxygen demand greater than 300 parts per million by weight of suspended solids, or any quantity of substances having the characteristics described in § 165-41, or an average daily flow greater than 2% of the total average daily sewage flow, shall be subject to review and approval of the Town Council. Where necessary in the opinion of the Town Council, the owner shall provide, at his expense, such preliminary treatment as may be necessary to:
(1)
Reduce the biochemical oxygen demand to 300 parts
per million and the suspended solids to 350 parts per million by weight;
(2)
Reduce objectionable characteristics or constituents to within the maximum limits provided for in § 165-41; or
(3)
Control the quantities and rates of discharge of such
water or wastes.
B.
Plans, specifications and any other pertinent information
relating to proposed preliminary treatment facilities shall be submitted
for the approval of the Town Council, and no construction of such
facilities shall be commenced until said approval is obtained in writing.
When required by the Superintendent, the owner
of any property served by a building sewer carrying industrial wastes
shall install a suitable control manhole in the building sewer to
facilitate observation, sampling and measurement of the wastes. Such
manhole shall be accessible and safely located and shall be constructed
in accordance with plans approved by the Superintendent. The manhole
shall be installed by the owner at his expense and shall be maintained
by him.
All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in §§ 165-41 and 165-44 shall be determined in accordance with Standard Methods for the Examination of Water and Sewage and shall be determined at the control manhole provided for in § 165-45 or upon suitable samples taken at said control manhole. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer nearest the point at which the building sewer is connected.
No statement contained in this article shall
be construed as preventing any special agreement or arrangement between
the Town and any industrial concern whereby an industrial waste of
unusual strength or character may be accepted by the Town for treatment;
provided, however, that such industrial concern shall make formal
application to the Town requesting exemption from existing requirements
and this request shall be publicly advertised and a public hearing
held. Any exemption granted shall be subject to payment for such direct
increased costs as well as amortizing any anticipated long-term costs
for damage to the sewer system as a result of granting the exemption,
billing for such costs to be made as an addition to the regular periodic
charges for use of the sewerage system.
