[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.
