Definitions. As used in these regulations, unless a different
meaning clearly appears in the context, the following terms shall have the
meanings indicated:
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 as determined by the procedure described in Standard
Methods.
BUILDING DRAIN
That part of the lowest horizontal piping of a drainage system which
receives the discharge from soil, waste and other drainage pipes inside the
walls of the building and conveys it to the building sewer which begins five
feet outside the inner face of the building wall.
BUILDING LATERAL
The connection from a trunk sewer system of the Village to the street
or curbline of the premises affected.
BUILDING SEWER
The extension from the building drain to the building lateral or
other place of disposal.
COMMISSION

Freeport or its authorized deputy, agent or representative.
COMPOSITE
A combination of individual, or continuously taken, samples 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.
GARBAGE
Solid wastes from the domestic and commercial preparation, cooking
and dispensing of food and from the handling, storage and sale of produce.
GRAB
An individual sample collected in less than 15 minutes.
INDUSTRIAL WASTES
Any liquid, gaseous, solid or other waste substance, or a combination
thereof, resulting from any process of industry, manufacture, trade or business
or from the development or recovery of any natural resources, as distinct
from sewage.
MAJOR CONTRIBUTING INDUSTRY
An industrial user of the Village wastewater facilities that has
a flow of 50,000 gallons or more per average work day, has in its wastewater
a toxic pollutant in toxic amounts as defined in standards issued under Section
307(a) of the Federal Water Pollution Control Act Amendments of 1972 and is
found by the permit issuance authority in connection with the issuance of
a National Pollutant Discharge Elimination System (NPDES) permit to a water
pollution control plant receiving the waste to have significant impact either
singly or in combination with other contributing industries on that water
pollution control plant or upon the quality of the effluent from that 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
(ppm).
NATURAL OUTLET
Any outlet, including storm sewers, into a watercourse, pond, ditch,
lake or other body of surface or ground water.
OBJECTIONABLE WASTE:
(1)
Garbage, refuse, decayed wood, sawdust, shavings, bark, sand, lime,
cinders, ashes, offal, oil, tar, dyestuffs, grit, abrasives, metal filings,
trimmings or any liquid or vapor having a temperature higher than 150°
F.
(2)
Any chemicals or chemical compounds of the following nature or characteristics
or having similarly objectionable characteristics: alcohols; arsenic and arsenicals;
creosols; formaldehydes; iodine; manganese; cyanide and other metal plating
wastes; mercury and mercurials; phenols and their derivatives; silver and
silver compounds; sulfonamides; toxic dyes (organic or mineral); zinc; all
strong oxidizing agents such as chromates, dichromates, permanganates, peroxide
and the like; greases and oils; compounds producing hydrogen sulfide, chlorinated
hydrocarbons or any other toxic material; flammable or explosive gases, either
upon acidification, alkalization, oxidation or reduction; strong reducing
agents, such as nitrites, sulfides, sulfites and the like; nonpesticide organics
or carcinogenic or other potentially harmful materials; flammable or explosive
liquids or solids; or radioactive materials.
(3)
Any matter which contains viable pathogenic bacteria in quantities larger
than normally encountered in raw domestic sewage or any matter which can reasonably
be expected to contain such viable pathogenic bacteria in such quantities.
(4)
Industrial wastes containing solids in solution which will precipitate
greater than 1,000 parts per million upon acidification (pH below 5.5), or
alkalization (pH above 9.5), or oxidation or reduction.
(5)
Industrial wastes having a viscosity exceeding 1.10 poises (absolute
viscosity) upon discharge or after acidification (pH below 5.5) or alkalization
(pH above 9.5).
(6)
Industrial waste having a temperature upon discharge of less than 32°
F. or more than 150°.
(7)
Industrial waste having a color of an intensity in excess of 500 parts
per million. In testing such intensity, samples shall be diluted with distilled
water to bring the range within 10 to 50 parts per million and judged on a
basis of intensity or transmission of light rather than true color (plantinum
cobalt standard).
(8)
Industrial waste having chemical characteristics in excess of the following
limits:
|
