COMPATIBLE POLLUTANT. Biochemical oxygen demand, suspended solids, pH, and fecal coliform bacteria, plus pollutants identified in the NPDES Permit if the treatment works was designed to treat such pollutants, and in fact does remove such pollutants to a substantial degree. The term SUBSTANTIAL DEGREE is not subject to precise definition, but generally contemplates removals in the order of 80% or greater. Minor incidental removals in the order of 10% to 30% are not considered substantial. Examples of the additional pollutants which may be considered compatible include chemical oxygen demand; total organic carbon; phosphorus and phosphorus compounds; nitrogen and nitrogen compounds; and fats, oils, and greases of animal or vegetable origin (except as prohibited where these materials would interfere with operation of the treatment works.)
EASEMENT. An acquired legal right for the specific use of land owned by others.
FECAL COLIFORM. Any of a number of organisms common to the intestinal tract of man and animals, whose presence in sanitary sewage is an indicator of pollution.

chemical products as well as oil of animal or vegetable origin such that will separate by gravity from wastewater by treatment in a pretreatment facility approved by the town.
GARBAGE. Solid wastes from the domestic and commercial preparation, cooking, and dispensing of food, and from the handling, storage and sale of produce.
IDEM. Indiana Department of Environmental Management.
INCOMPATIBLE POLLUTANT. Any pollutant that is not defined as a compatible pollutant, including nonbiodegradable dissolved solids, and further defined in Regulation 40 C.F.R. Part 403.
INDUSTRIAL WASTES. The liquid wastes from industrial manufacturing processes, trade, or business as distinct from sanitary sewage.
INFILTRATION/INFLOW. The total quantity of water from both infiltration and inflow without distinguishing the source.
INFILTRATION. The water entering a sewer system, including building drains and sewers, from the ground, through such means as, but not limited to, defective pipes, pipe joints, connections or manhole walls. (INFILTRATION does not include and is distinguished from inflow.)
INFLOW. The water discharged into a sewer system, including building drains and sewers, from such sources as, but not limited to, roof leader, cellar, yard and area drains, foundation drains, unpolluted cooling water discharges, drains from springs and swampy areas, manhole covers, cross connections from storm sewers, catch basins, storm waters, surface runoff, street wash waters or drainage. (INFLOW does not include and is distinguishable from infiltration.)
INSPECTOR. The person or persons duly authorized by the town, through its Town Council , to inspect and approve the installation of building sewers and their connection to the public sewer system.
MAINTENANCE. To keep the building sewer in good operational condition - open and free flowing.
MAJOR CONTRIBUTOR. A contributor that:
(1) Has a flow of more than 25,000 gallons per average workday;
(2) Has in its waste a toxic pollutant in toxic amounts as defined in Section 307(a) of the Federal Act or state statutes and rules;
(3) Has a flow greater than 5% of flow carried by the municipal system receiving the waste;
(4) Is found by the town, state control agency or the U.S. Environmental Protection Agency (USEPA) to have significant impact, either singly or in connection with other contributing industries, on the wastewater treatment system, the quality of sludge, the system's effluent quality, or air emissions generated by the system.
NATURAL OUTLET. Any outlet into a watercourse, pond, ditch, lake or other body of surface or ground water.
NPDES PERMIT. National Pollutant Discharge Elimination System Permit setting forth conditions for the discharge of any pollutants to the navigable water of the United States pursuant to Pub. L. 95-217, § 402, being 33 USC 1342.
PERSON. Any individual, firm, company, association, society, corporation or group.
pH. The logarithm of the reciprocal of the weight of hydrogen ions in grams per liter of solution.
PHOSPHORUS (or P). The chemical element phosphorus, total. The laboratory determinations shall be made in accordance with procedures set forth in the "Standards Methods," as defined herein.
PRETREATMENT. The reduction of the amount of pollutants, the elimination of pollutants, or the alteration of the nature of pollutant properties in wastewater to a less harmful state prior to or in lieu of
discharging or otherwise introducing such pollutants into the town's sanitary sewer system. The reduction or alteration can be obtained by physical, chemical or biological processes, process changes or by other means, except as prohibited by 40 C.F.R. § 403.6(d); and shall include all applicable rules and regulations contained in the Code of Federal Regulations, as published in the Federal Register, under Pub. L. 95-217, § 307, 33 USC 1317, under regulation 40 C.F.R. Part 403, pursuant to the Act, and amendments.
PROPERLY SHREDDED GARBAGE. The wastes from the preparation, cooking and dispensing of food 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 one-half inch in any diameter.
PROPERLY SHREDDED GARBAGE. The wastes from the preparation, cooking, and dispensing of food that have 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 one-half inch in any dimension.
