Unless the context specifically indicates otherwise, the meanings
of terms used in these rules and regulations shall be as follows:
BOD (denoting "biochemical oxygen demand")
The quantity of oxygen utilized in the biochemical oxidation
of organic matter under standard laboratory procedure in five days
at 20° C, expressed in milligrams per liter.
BUILDING DRAIN
That part of the lowest horizontal piping of a drainage system
that receives only sanitary waste discharged from pipes inside the
walls of the building and conveys it to the building sewer, beginning
10 feet outside the inner face of the building wall.
BUILDING SEWER
The extension from the building drain to the public sewer
or other place of disposal.
CHLORINE DEMAND
The amount of chlorine which must be added to waters or wastes
to produce a residual chlorine content in such waters or wastes.
COMMISSIONER
The Commissioner of Environmental Protection for the State
of Connecticut.
COOLING WATER
Includes clean wastewater from air-conditioning, industrial
cooling, condensing and similar apparatus and from hydraulically powered
equipment. In general, cooling water will include only water which
is sufficiently clean and unpolluted to admit of being discharged
without treatment or purification (except for removal of excessive
heat) into any natural open stream or watercourse without offense.
DRAIN LAYER
A person who holds an appropriate license issued by the State
of Connecticut covering the installation of building sewers as defined
above.
GARBAGE
Solid wastes from the preparation, cooking and dispensing
of food and from the handling, storage and sale of produce.
INDUSTRIAL WASTES
The liquid wastes from industrial processes, trade or business,
as distinct from sanitary sewage.
NATURAL OUTLET
Any watercourse, pond, ditch, lake or other body of surface
or groundwater.
NPDES
National Pollutant Discharge Elimination System, as administered
by the United States Environmental Protection Agency to set pollutant
limits for point source discharges.
PASS-THROUGH
A discharge that exits the POTW into waters of the United
States in quantities or concentrations that, alone or in conjunction
with a discharge or discharges from other sources, is a cause of a
violation of any requirement of Simsbury's NPDES permit, including
an increase in the magnitude or duration of a violation.
PERSON
Any individual, firm, company, association, society, corporation,
group or any other legal entity; or their legal representatives, agents,
or assigns.
pH
A term that quantifies the intensity of acid or base solutions.
A pH of 7 is considered neutral, with acidity increasing as the pH
decreases.
POLLUTANT
Dredged spoil, solid waste, incinerator residue, filter backwash,
sewage, garbage, sewage sludge, munitions, medical wastes, chemical
wastes, biological materials, radioactive materials, heat, wrecked
or discarded equipment, rock, sand, cellar dirt, municipal, agricultural
and industrial wastes, and certain characteristics of wastewater (e.g.,
pH, temperature, TSS, turbidity, color, BOD, COD, toxicity, or odor).
POTW
Publicly owned treatment works. This includes any devices
or systems used in the collection, storage, treatment, recycling,
and reclamation of sewage or industrial wastes of a liquid nature,
and any conveyances which convey wastewater to a treatment plant.
PRETREATMENT
The reduction of the amount of pollutants, the elimination
of pollutants, or the alteration of the nature of pollutant properties
in wastewater prior to or in lieu of introducing such pollutants into
the POTW. This reduction or alteration can be obtained by physical,
chemical, or biological processes, by process changes, or by other
means, except by diluting the concentration of the pollutants (unless
dilution is allowed by an applicable pretreatment standard).
PRIVATE SEWER SYSTEM
Pipelines or conduits, pumping stations, force mains, and
all other constructions, devices, appurtenances, and facilities used
for collecting or conducting waterborne sewage, industrial waste,
or other wastes to a point of disposal or treatment that is owned
by a nongovernmental entity and which services or is proposed to service
more than one structure.
PROPERLY SHREDDED GARBAGE
The wastes from the preparation, cooking and dispensing of
food which have been shredded to such a degree that all particles
will be carried freely under the flow conditions normally prevailing
in public sewers, with no particle greater than 1/2 inch (1.27 centimeters)
in any dimension.
PUBLIC SEWER
A sewer in which all owners of abutting properties have equal
rights and which is controlled by public authority.
SANITARY SEWAGE
A combination of the water-carried wastes from residences,
business buildings, institutions and industrial establishments.
SANITARY SEWER
A sewer which carries sewage and into which storm, surface
and ground waters are not intentionally admitted.
SEWAGE WORKS
All facilities for collecting, pumping, treating and disposing
of sewage.
SEWER
A pipe or conduit for carrying sewage.
SEWER SERVICE AREA
That area shown on the map entitled "Simsbury Sewer Service
Area," dated November 2008, or current version as may be from time
to time amended.
SLUG
Any discharge of water, sewage or industrial waste which,
in concentration of any given constituent or in quantity of flow,
exceeds for any period of duration longer than 15 minutes, more than
five times the average flow or concentration that is generally experienced
for such an interval of time during the course of 24 hours of normal
operation.
STORM SEWER or STORM DRAIN
A sewer which carries storm and surface waters and drainage,
but excludes sewage and polluted industrial wastes, other than unpolluted
cooling water.
SUBSOIL DRAINAGE
Includes water from the soil percolating into subsoil drains
and through foundation walls or basement floors, or from underground
pipes or similar sources.
SUPERINTENDENT
Refers to the authorized agent or representative of the Water
Pollution Control Authority who is responsible for the operation and
management of the sewer collection system and the associated water
pollution control facility.
SUSPENDED SOLIDS
Solids that either float on the surface of, or are in suspension
in, water, sewage or other liquids, and which are removable by laboratory
filtering.
WASTEWATER
Liquid and water-carried industrial wastes and sewage from
residential dwellings, commercial buildings, industrial and manufacturing
facilities, and institutions, whether treated or untreated, which
are contributed to the POTW.
WATERCOURSE
A channel in which a flow of water occurs either continuously
or intermittently.
WATER POLLUTION CONTROL PLAN
The document that describes where sewers are to be located
and not located within the Town of Simsbury. Included in the Water
Pollution Control Plan is the Sewer Service Area Map.
