E. Pollutants, including septage and oxygen-demanding pollutants (BOD,
COD, suspended solids, phenols, etc.), at a rate or concentration
that, either alone or in conjunction with discharges from other sources,
may result in a violation of the Town's NPDES permit;

sewerage system that may cause acute public or worker health and safety
problems;
H. Trucked or hauled pollutants, except as approved by and at discharge
points designated by the Public Works Director;
I. Noxious or malodorous liquids, gases, solids, or other wastewater
that, either alone or by interaction with other substances, may create
a public nuisance or hazard or prevent entry into the sewerage system
for maintenance or repair;
J. Wastewater that imparts color that cannot be removed by the treatment
process;
K. Wastewater containing any radioactive wastes or isotopes except in
compliance with applicable state and federal regulations;
L. Stormwater, surface water, groundwater, artesian well water, roof
runoff, subsoil drainage, swimming pool drainage, condensate, deionized
water and non-contact cooling water;
M. Sludge, screenings, or other residues from the pretreatment of industrial
wastes;
O. Detergents, surfactants, or other substances which may cause excessive
foaming;
P. Fats, wax, oils, greases of animal or vegetable origin, petroleum,
cutting oil or mineral oil, whether emulsified or not, in concentrations
greater than 100 mg/l or in amounts that will cause interference or
pass-through. Floatable oil shall not exceed 20 mg/l or contain substances
which may solidify or become viscous at temperatures between 32°
F. and 150° F.
Q. Overflow from holding tanks or other receptacles storing organic
wastes;
R. Wastewater with a concentration of pollutants in excess of the following
limits in mg/l; All metals are to be measured as total metals:

In accordance with Section 22a-430b of the CGS, dischargers
of industrial waste shall be subject to all registration, processing,
operation, recordkeeping, reporting and other requirements of individual
or general permits issued by the DEEP, including but not limited to:
A. A General Permit for the Miscellaneous Discharges of Sewer Compatible
(MISC) Wastewater (DEEP-WPED-GP-012) applicable to wastewater, including
but not limited to air compressor condensate and blowdown, boiler
blowdown, building maintenance wastewater, commercial laundry wastewater,
contact cooling and heating water, cutting and grinding wastewater,
fire-suppression system testwater, food-processing wastewater, hydrostatic
pressure testing wastewater, non-contact cooling water, non-destruct
testing rinsewater, printing and photographic processing wastewater,
tumbling and cleaning wastewater, water treatment wastewater, fire
suppression testing wastewater, and swimming pool wastewater.
B. A General Permit for Domestic Sewage (DEP-WPED-GP-018) applicable
to discharges of domestic sewage from a community sewerage system
greater than 1% of the average daily design flow of the WWTP. Privately
owned community sewerage systems (such as those at condominiums) are
to be properly managed and have a valid community sewerage system
agreement with the municipality receiving the discharge as required
by Section 7-246f of the General Statutes.
C. A General Permit for Vehicle Maintenance Wastewater (DEP-PERD-GP-010)
applicable to wastewater generated by floor washdown and incidental
drippage from vehicles as a result of routine servicing operations
and washing of vehicle exteriors or steam cleaning of engines. The
maximum daily flow of all discharges of vehicle maintenance wastewater
generated at a single site must not exceed 15,000 gallons per day.
D. A General Permit for the Discharge of Wastewater Associated With
Food Preparation Establishments (DEEP-WATERP&S-GP-001) applicable
to wastewater discharged from restaurants, hotel kitchens, hospital
kitchens, school kitchens, bars, factory cafeterias, retail bakeries
and clubs. At no time shall the pH of the wastewater discharged from
the grease trap/interceptor, AGRU or other approved unit and prior
to mixing with any other wastewater from the facility be less than
5.0 nor greater than 10.0 standard units at any time, nor shall the
concentration of fats, oils, and grease in wastewater from the grease
trap/interceptor, AGRU, or other approved unit and prior to mixing
with any other wastewater from the facility exceed 100 milligrams
per liter.
E. A General Permit for Food Processing Wastewater (DEP-WD-GP-006) applicable
to wastewaters generated by the manufacture and storage of food and
beverage for human and animal consumption, including but not limited
to laboratories associated with or the cleaning and maintenance of
areas associated with storage, processing, packaging, and disposal
of raw materials, products, and by-products, and composting operations.
Total discharges of food-processing wastewater cannot exceed 50,000
gallons per day and must be either discharged directly to a POTW or
hauled there. For those activities having food-processing wastewater
discharges with a maximum daily flow greater than 1,000 gallons per
day, a registration is required to be submitted to the Department.
For discharges which contain any of the substances listed in Attachment
B (Toxic and Hazardous Pollutants and Their Maximum Concentrations)
of the general permit in concentrations exceeding the concentrations
listed therein, registration is required to be submitted and approved
in writing by the Department. No registration is required for those
activities having maximum daily discharges equal to or less than 1,000
gallons per day and which do not contain any of the substances listed
in Attachment B in concentrations exceeding the maximum concentrations
listed therein.
F. A General Permit for Groundwater Remediation Wastewater to a Sanitary
Sewer (DEP-WD-GP-007) applicable to discharges of groundwater remediation
wastewater generated during the process of investigating and remediating
groundwater and soil. The maximum daily flow of all discharges may
not exceed 5% of the POTW's design capacity and must be either
discharged directly to the POTW or hauled there. Registration is required
to be submitted to the department in order for the discharges to be
authorized by this general permit.
G. A General Permit for Categorical Industrial User Wastewater to a
Publicly Owned Treatment Works (DEEP-WPED-GP-008) applicable to wastewaters
discharging from facilities subject to 40 CFR 403.6, National pretreatment
standards: categorical standards. The first categorical wastewater
covered by this general permit is metal finishing wastewater, which
is wastewater subject to the provisions of 40 CFR Part 413 (Electroplating
Point Source Category) or 40 CFR Part 433 (Metal Finishing Point Source
Category).
The Town reserves the right to reject the discharge of any wastewater
and to establish, by regulation or in wastewater discharge permits,
more stringent standards or requirements on discharges to the sewerage
system.
It shall be a violation of these regulations to maliciously,
willfully, or negligently break, damage, destroy, uncover, deface,
or tamper with any structure, appurtenance, or equipment which is
a part of the sewerage system.
