of 20º C. as determined by appropriate procedures described in
the definition of "standard methods."
BOARD
The Board of Commissioners of the Port Washington Water Pollution
Control District.

which receives the discharge from soil, waste and other drainage pipes
inside the walls of the building and conveys it to the building sewer
beginning five feet outside the inner face of the building walls.
BUILDING SEWER
The extension from the building drain to the public sewer
or other place of disposal, also called "house connection."
CHEMICAL OXYGEN DEMAND (COD)
The measure of chemically decomposable material in domestic
or industrial wastewater as represented by the oxygen utilized as
determined by the appropriate procedure described in the definition
of "standard methods."

A sewer intended to receive both wastewater and storm- or
surface water.
COMPOSITE

obtained at regular intervals over the entire discharge day. The volume
of each sample shall be proportional to the discharge flow rate. For
a continuous discharge, a minimum of 24 individual grab samples (at
hourly intervals) shall be collected and combined to constitute a
twenty-four-hour composite sample. For intermittent discharges of
four to eight hours' duration, grab samples shall be taken at a minimum
of thirty-minute intervals. For intermittent discharges of less than
four hours' duration, grab samples shall be taken at a minimum of
fifteen-minute intervals.
DISCHARGER
Any person that discharges or causes a discharge to a public
sewer.
DISTRICT
The Port Washington Water Pollution Control District in the
Town of North Hempstead, Nassau County, New York.
DOMESTIC WASTEWATER
The water-carried wastes produced from noncommercial or nonindustrial
activities and which result from normal living processes.

and dispensing of food and from the handling, storage and sale of
produce.
GRAB
An individual sample collected in less than 15 minutes.
INDUSTRIAL WASTEWATER
All water-carried wastes and wastewater of the district,
excluding domestic wastewater and unpolluted water, and includes all
wastewater from any producing, manufacturing, processing, institutional,
commercial, agricultural or other operation where the wastewater discharged
includes significant quantities of wastes of nonhuman origin.
MAJOR CONTRIBUTING INDUSTRY
An industrial user of the district-owned wastewater facilities
that:
A.
Has a flow of 50,000 gallons or more per average
workday.
B.
Has a flow of greater than 5% of the flow carried
by the district wastewater facilities receiving the waste.
C.
Has in its wastewater a toxic pollutant in toxic
amounts as defined in standards issued under § 307(a) of
the Federal Water Pollution Control Act Amendments of 1972.
D.
Is found by the permit-issuance authority, in
conjunction with the issuance of an NPDES permit to the district wastewater
treatment plant receiving the wastewater, to have significant impact,
either singly or in combination with other contributing industries,
on that wastewater treatment plant or upon the quality of effluent
from that wastewater treatment plant.
MILLIGRAMS PER LITER (mg/l)
A weight-to-volume ratio which, when multiplied by the factor
8.34, shall be equivalent to pounds per million gallons of water;
parts per million parts (ppm).
NATURAL OUTLET
Any outlet, including storm sewers, into a watercourse, pond,
ditch, lake or other body of surface or ground water.
NPDES PERMIT
Any permit or equivalent document or requirement issued to
regulate the discharge of pollutants from point sources into the navigable
waters, the contiguous zone and the ocean by the Administrator of
the United States Environmental Protection Agency pursuant to §§ 402
and 405 of the Federal Water Pollution Control Act Amendments of 1972.
PERSON
Includes any corporation, organization, government or governmental
subdivision or agency, business, trust, partnership, association,
individual or other legal entity.
pH
The logarithm of the reciprocal of the weight of hydrogen
ions in grams per liter of solution.
PRETREATMENT
Treatment of wastewaters from sources before introduction
into the wastewater facilities.
PROPERLY SHREDDED GARBAGE
Garbage that has 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
in any dimension.
PUBLIC SEWER
A sewer in which all owners of abutting properties have equal
rights and which is controlled by the district.
SANITARY SEWER
A sewer which carries wastewater and to which storm-, surface
and groundwaters are not intentionally admitted.
SEWER
A pipe or conduit for carrying wastewater or drainage water.
SLUG
Any discharge of wastewater 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 twenty-four-hour
concentration of flows during normal operation and shall adversely
affect the collection system and/or the performance of the wastewater
treatment plant.
STANDARD METHODS
The examination and analytical procedures set forth in the
latest edition, at the time of analysis, of Standard Methods for the
Examination of Water and Wastewater, as prepared, approved and published
jointly by the American Public Health Association, the American Water
Works Association and the Water Pollution Control Federation.
STORM SEWER (sometimes termed STORM DRAIN)
A sewer for conveying stormwater from street runoff and other
drainage areas, groundwater, subsurface water or unpolluted water
and into which domestic and industrial wastewaters are not intentionally
passed.

of "standard methods."
WASTE
Rejected, unused or superfluous substances in liquid, gaseous
or solid state resulting from domestic, agricultural or industrial
activities.
WASTEWATER
The spent water of the district. From the standpoint of sources,
it may be a combination of the liquid and water-carried wastes from
