Definition of terms. As used in this section, the following terms
shall have the meanings indicated:
BIOCHEMICAL OXYGEN DEMAND (BOD)
The quantity of oxygen, expressed in parts per million by
weight, utilized in the biochemical oxidation of organic matter under
standard laboratory conditions for five days at a temperature of 20°
C. The laboratory determinations shall be made in accordance with
procedures set forth in Standard Methods.
CLEAR WATER
All water which conforms to the natural analytical quality
of water and not having been polluted or contaminated by use.
GBMSD
The Green Bay Metropolitan Sewerage District.
INDUSTRIAL WASTE
Any solid, liquid or gaseous substance discharged, permitted
to flow or escaping from any industrial, manufacturing, commercial
or business establishment or process or from the development, recovery
or processing of any natural resources.
NORMAL CONCENTRATION
(1)
A five-day, 20° C., BOD of not more than 200 parts per million.
(2)
A suspended solid content of not more than 200 parts per million.
(3)
Phosphorus content of not more than 12 parts per million.
NORMAL WASTEWATER
Sanitary wastewater or other wastes in which BOD or suspended
solids concentrations do not exceed normal concentrations.
PARTS PER MILLION
A weight-to-weight ratio; the parts per million value multiplied
by the factor 8.345 shall be equivalent to pounds per million gallons
of water.
PERSON
Any person, natural or artificial, including any individual,
firm, company, municipal or private corporation, association, society,
institution, enterprise, governmental agency or other entity.
pH
The logarithm (Base 10) of the reciprocal of the hydrogen
ion concentration expressed in moles per liter. It shall be determined
by one of the procedures outlined in Standard Methods.
PHOSPHORUS
Elemental phosphorus determined by and in accordance with
the procedures set forth in Standard Methods.
PUBLIC SEWER
A sewer provided by or subject to the jurisdiction of the
Village of Allouez or Green Bay Metropolitan Sewerage District.
SANITARY SEWER
A sewer that conveys wastewater and into which stormwater,
surface water, and groundwater or unpolluted industrial wastes are
not admitted.
SANITARY WASTEWATER
The waste from water closets, urinals, lavatories, sinks,
bathtubs, showers, household laundries, cellar floor drains, garage
floor drains, bars, soda fountains, refrigerator drips and drinking
fountains.
SLUG
A sudden increase in wastewater discharge that may tend to
overload the receiving sewer.
STANDARD METHODS
The examination and analytical procedures set forth in the
most recent edition of Standard Methods for the Examination of Water
and Wastewater published jointly by the American Public Health Association,
the American Water Works Association, and the Water Environment Federation.
SUSPENDED SOLIDS
Solids that either float on the surface of or are in suspension
in water, wastewater, or industrial waste and which are removable
by a laboratory filtration device. Quantitative determination of suspended
solids shall be made in accordance with procedures set forth in Standard
Methods.
TOTAL KIELDAHL NITROGEN (TKN)
The sum of free ammonia and organic nitrogen compounds as
determined by standard laboratory procedures in accordance with Standard
Methods. TKN is a measurable quantity which is used as a basis for
determining ammonia treatment costs.
