Unless the context specifically indicates otherwise, the following
words and terms used in these rules and regulations shall have the
following meanings:
ABNORMAL INDUSTRIAL WASTE
Any industrial waste having a suspended solid content or
BOD appreciably in excess of that normally found in municipal sewage.
For the purposes of these regulations, any industrial waste containing
more than 275 milligrams per liter of suspended solids, or having
a BOD in excess of 300 milligrams per liter, shall be considered an
abnormal industrial waste regardless of whether or not it contains
other substances in concentrations differing appreciably from those
normally found in municipal sewage.
AUTHORITY
The Collier Township Municipal Authority, Allegheny County,
Pennsylvania, situated in Collier Township, Allegheny County, Pennsylvania.
BIOCHEMICAL OXYGEN DEMAND (BOD) OF SEWAGE OR INDUSTRIAL WASTE
The quantity of oxygen utilized in the biochemical oxidation
of the organic matter in said sewage or industrial waste under standard
laboratory procedure in five days at 20° C. (under aerobic conditions),
expressed in milligrams per liter by weight. It shall be determined
by one of the acceptable methods described in the latest edition of
Standard Methods for the Examination of Water and Wastewater.
BOARD
The elected and appointed members of the Board of the Collier
Township Municipal Authority, Allegheny County, Pennsylvania, as now
or hereafter constituted, and its duly authorized agents or representatives.
COMBINED SEWER
A sewer designed to receive both sewage and stormwater runoff
which has been approved for such purpose.
GARBAGE
Solid wastes from the preparation, cooking and dispensing
of food and from the handling, storage and sale of produce.
INDUSTRIAL WASTES
Any liquid, gaseous or waterborne wastes from industrial
processes or commercial establishments, as distinct from sanitary
sewage.
OCCUPIED BUILDING
Any structure erected and intended for continuous or periodic
habitation, occupancy or use by human beings or animals, and from
which structure sanitary sewage and industrial wastes, or either thereof,
is or may be discharged.
PERSON
Includes natural persons, partnerships, associations and
corporations, public or private.
pH
The logarithm to the base 10 of the reciprocal of the hydrogen
ion concentration expressed in moles per liter. It shall be determined
by one of the acceptable methods described in the latest 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.
PROPERLY SHREDDED GARBAGE
The wastes from the preparation, cooking and dispensing of
food and from the handling, storage and sale of produce that have
been shredded to such 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 SANITARY SEWAGE SYSTEM or SEWER SYSTEM
All sanitary or combined sewers, all pumping stations, inverted
siphon, all force mains, all sewage treatment works, and all other
sewerage facilities owned or leased and operated by the Authority
for the collection, transportation and treatment of sanitary sewage
and industrial wastes, together with their appurtenances, and any
additions, extensions or improvements thereto. It shall also include
sewers within the Authority's service area which serve one or more
persons and discharge into the public sanitary sewerage system even
though those sewers may not have been constructed by the Authority
and are not owned or maintained by the Authority. It does not include
separate storm sewers or culverts which have been constructed for
the sole purpose of carrying storm and surface runoff, the discharge
from which is not and does not become tributary to the sewage treatment

SANITARY SEWER
A sewer which carries sewage and to which stormwater, surface
water and groundwaters are not intentionally admitted.

buildings, institutions, and industrial and commercial establishments,
together with such groundwater, surface water or stormwater as may
be present.
SEWER
A pipe or conduit for carrying sewage.
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 twenty-four-hour concentration or flows during
normal operation.
STORM SEWER
A sewer which is intended to carry stormwater runoff, surface
waters, groundwater drainage, etc., but which is not intended to carry
any sanitary sewage or polluted industrial waste.
STORMWATER RUNOFF
That portion of the rainfall which reaches a channel, trench,
sewer or sink.
SUSPENDED SOLIDS
Solids that either float on the surface or are in suspension
in water, sewage, industrial waste or other liquids, and which are
removable by laboratory filtration. The quantity of suspended solids
shall be determined by one of the acceptable methods described in
the latest edition of Standard Methods for the Examination of Water
and Wastewater.
UNPOLLUTED WATER OR WASTE
Any water or waste containing none of the following: free
or emulsified grease or oil; pH less than 6.0 or greater than 8.5;
phenols or other substances imparting taste and odor to receiving
waters; toxic or poisonous substances in suspension, colloidal state
or solution; obnoxious or odorous gases. It shall contain not more
than 500 milligrams per liter by weight of dissolved solids of which
not more than 250 milligrams per liter shall be as chloride and not
more than 10 milligrams per liter each of suspended solids and BOD.
The color shall not exceed five color units. Analyses for any of the
above-mentioned substances shall be made in accordance with the latest
edition of Standard Methods for the Examination of Water and Wastewater.
WATER AUTHORITY
Any publicly or privately owned duly authorized agency, corporation
or organization which is the approved purveyor of the public water
