(a)Â
The purpose of this article is to facilitate the maximum beneficial
public use of the City's sewer services and facilities while preventing
blockages of the sewer lines resulting from discharges of fats, oils,
and grease (FOG) to the sewer facilities, and to specify appropriate
FOG discharge requirements for food service establishments (FSEs).
(b)Â
This article establishes quantity and quality standards on all wastewater
and/or waste discharges containing FOG, which may alone or collectively
cause or contribute to FOG accumulation in the sewer facilities causing
or potentially causing or contributing to the occurrence of sewer
backups and/or sanitary sewer overflows (SSOs) or combined sewer overflows
(CSOs).
(c)Â
The specific objectives of this article are to:
(1)Â
Prevent the introduction of wastewaters containing fats, oils
and grease (FOG) in amounts which may cause excessive maintenance
of sewer lines, stoppages or obstruction of flow, or in any other
way prevent or inhibit operation of the publicly owned treatment works
(POTW), including the sanitary sewer collection system and/or treatment
plant;
(2)Â
Prevent the introduction of pollutants that may be incompatible
with the POTW;
(3)Â
Enable the City of Biddeford (City) to comply with its National
Pollutant Discharge Elimination System (NPDES) permit conditions,
sludge disposal conditions, sludge use and disposal requirements,
and any other federal or state laws to which the POTW is subject;
and
(4)Â
Protect the environment and the health, safety and welfare of
the public and the POTW workers by regulating the pretreatment, transport
and disposal of FOG-related wastes.
(d)Â
This article enables the City to protect public health in conformity with all applicable local, state, and federal laws relating thereto, including but not limited to the Clean Water Act (33 U.S.C. § 1251 et seq.) and the General Pretreatment Regulations (40 CFR 403). This article shall be interpreted in accordance with the definitions set forth in Sec. 70-241. The provisions of this article shall apply to the direct or indirect discharge of wastewater or waste containing FOG carried to the sewer facilities of the City.
(e)Â
This rule shall apply to all food service establishment (FSE) users
and to persons or entities outside the City's political boundary who
are, by permit, contract, or agreement with the City, users of the
Biddeford POTW wastewater facilities or collection system.
(a)Â
Unless otherwise defined herein, terms related to water quality shall
be as adopted in the latest edition of Standard Methods for Examination
of Water and Wastewater, published by the American Public Health Association,
the American Water Works Association and the Water Environment Federation.
The testing procedures for waste constituents and characteristics
shall be as provided in 40 CFR 136 (Code of Federal Regulations).
(b)Â
Unless a provision explicitly states otherwise, terms and phrases as defined in Chapter 70, Sewer Use Rule of the City of Biddeford, Maine (most recent version), shall apply.

discharged by food service establishments in an amount that, alone
or collectively, causes or creates a potential for sewer backups and/or

Local public codes office responsible for, among other things,
implementation and enforcement of the International Plumbing Code.
Municipal division charged with operating the City's sewage
