Unless the context specifically indicates otherwise, the meanings
of terms used in this Part 1 shall be as follows:
APPLICANT
Any person requesting approval to discharge wastewaters into
municipal facilities or for a new connection to the public system.
AVERAGE DAILY FLOW
The total volume of sewage in gallons measured at a metering
station or other point during a continuous period of 365 days divided
by 365.
BIOCHEMICAL OXYGEN DEMAND (BOD)
The quantity of dissolved oxygen, expressed in milligrams
per liter, used in the biochemical oxidation of wastewater in five
days at 20° C. (68° F.) under standard laboratory procedures.
BUILDING DRAIN
That part of the lowest horizontal piping of a drainage system
which receives the discharge from soil, waste, and/or other stacks
inside the building and terminates 10 feet outside the inner face
of the building wall.

the inner face of the building wall and extends to a public sewer,
private sewer or other place of wastewater disposal.

Pollutant discharge limitations for specific industrial user
categories promulgated under federal law by the U.S. Environmental
Protection Agency.
CHEMICAL OXYGEN DEMAND (COD)
The measure of the oxygen-consuming capacity of inorganic
and organic matter present in water or wastewater. It is expressed
as the amount of oxygen consumed from a chemical oxidant in a specific
test. It does not differentiate between stable and unstable organic
matter and thus does not necessarily correlate with biochemical oxygen
demand.

to be added to water, wastewater, or other liquids to achieve a combined
chlorine residual of one milligram per liter after 15 minutes of contact.

A sewer receiving and conveying both sanitary wastewater
and surface runoff from storms.
DIRECTOR
The Director of Public Works of the City or his authorized
deputy or representative.
DOMESTIC WASTEWATER

sanitary conveniences such as toilets, washrooms, urinals, sinks,
showers, drinking fountains, laundry rooms, kitchens, cafeterias and
floor drains, essentially free of industrial wastes or toxic materials.
EXCESSIVE

which, in the judgment of the municipality:
A.
Will cause damage to any facility;
B.
Will be harmful to a wastewater treatment process;
C.
Cannot be removed in the treatment works to the degree required
in the limiting stream classification standards of the Connecticut
River and/or its tributaries;
D.
Can otherwise endanger life or property; or
E.
Can constitute a nuisance.
FACILITIES
Includes structures, conduits, pumping stations, treatment
and disposal works, and other appurtenances for the purpose of collecting,
treating and disposing of domestic and/or industrial wastewater.
GARBAGE
The wastes resulting from the handling, preparation, cooking
and serving of food. It is composed largely of putrescible organic
matter, usually with a high natural moisture content.
INDUSTRIAL USER
An industry discharging industrial wastewater to a public
sewer.
INDUSTRIAL WASTEWATER
The liquid wastes from industrial manufacturing processes,
laboratories, trades or businesses which predominate, as distinct
from domestic wastewaters.
INDUSTRY
An establishment with facilities for mechanical, testing,
trade, or manufacturing purposes.
INTERCEPTOR SEWER
A sewer, located in public and/or private property, which
collects the entire flow from a number of public and/or private sewers,
conveys the flow to a suitable collection point for final discharge
to a place of wastewater treatment and is entirely controlled by the
municipality.
INTERFERE
A discharge by an industrial user which, alone or in conjunction
with discharges by other sources, inhibits or disrupts the City's
wastewater works, its treatment processes or operations, or its sludge
processes, use or disposal and which is a cause of a violation of
any requirement of the City's NPDES permit (including an increase
in the magnitude or duration of a violation) or of the prevention
of sewage sludge use or disposal by the City in accordance with the
following statutory provisions and regulations or permits issued thereunder
(or more stringent state or local regulations): Section 405 of the
Clean Water Act, the Solid Waste Disposal Act (SWDA) [including Title
II, more commonly referred to as the "Resource Conservation and Recovery
Act (RCRA)," including state regulations contained in any state sludge
management plan prepared pursuant to Subtitle D of the SWDA], the
Clean Water Act, the Toxic Substances Control Act, and the Marine
Protection Research and Sanctuaries Act.
LICENSED CONTRACTOR
Any contractor licensed by the Director of Public Works to
install building sewers, private sewers and public sewers in the City.
MAXIMUM DAILY FLOW
The highest volume, in gallons, measured at a metering station
or other point during any continuous twenty-four-hour period.
NATURAL OUTLET
Any outlet into a watercourse, pond, ditch, lake or other
body of surface water or groundwater.
PASS-THROUGH
The discharge of pollutants through the City's wastewater
works into navigable waters in quantities or concentrations which,
alone or in conjunction with discharges from other sources, are a
cause of a violation of any requirement of the City's NPDES permit
(including an increase in the magnitude or duration of a violation).
PERSON
Any individual, firm, company, association, society, corporation,

concentration in grams per liter of solution.
PRIVATE DRAIN
Any drain located on private property and not under the full

PRIVATE SEWER
Any sewer located on private property that collects and conveys
wastewater from two or more building sewers, discharges into a public

of Public Works.
PROPERLY SHREDDED GARBAGE
