A. 
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.

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.
PREMISES ACCESSIBLE TO THE PUBLIC SANITARY SEWAGE SYSTEM
Any real estate abutting on or adjoining or having access to any street, alley or right-of-way in which a sewer is located which ultimately connects to the public sanitary sewage system.
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 facilities.

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

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 supply within the limits of the Authority's service area.
