BENEFICIAL USER. Users of the waters of the state that may be protected against quality degradation including domestic, municipal, agricultural and industrial supply, power generation, recreation, aesthetic enjoyment, navigation and the preservation and enhancement of fish, wildlife and other aquatic resource and reserves, and other uses, both tangible and intangible as specified by federal or state law.
BIOCHEMICAL OXYGEN DEMAND or BOD. The empirical test run in accordance with latest edition of Standard Method for Analysis of Water and Wastewater, published by American Public Health Association and Water Pollution Control Federation or Methods for the Analysis of Water and Wastes published by EPA to determine the relative oxygen requirements of wastewaters’ effluents and polluted waters. BOD is a measure of the oxygen required to oxidize the organic matter in a sample through the action of microorganisms in that sample.
BUILDING SEWER. A sewer conveying wastewater from the premises of a user to a county sewer for treatment.
CHEMICAL OXYGEN DEMAND or COD. The quantity of oxygen used in the chemical oxidation or decomposition of organic substances in a sample.
COMPATIBLE POLLUTANT. Pollutants such as BOD, TSS, pH, oil and grease, ammonia nitrogen (NHj) and fecal coliform bacteria, plus any additional pollutants identified by the county’s National Pollutant Discharge Elimination System (NPDES) permit, or any pollutants that the county’s treatment works are designed to treat. The pollutants shall be amenable to the county’s biological waste treatment process; shall not cause the county to use additional chemicals, extra personnel or cause undue wear or operating expenses; shall not cause the county’s wastewater treatment plant to exceed effluent limitations as set forth in NPDES permit.
DOMESTIC WASTES. The liquid wastes from bathrooms, toilet rooms, home kitchens and home laundries.
EPA. The Federal Agency named the Environmental Protection Agency.
EXCESSIVE RADIATION DOSE. A dose of radiation in excess of the maximum permissible dose. MAXIMUM PERMISSIBLE DOSE shall mean a dose of radiation to any part of the body, internal and external or both, that, in the light of current knowledge, is not expected to cause appreciable bodily injury to a person at any time during his or her lifetime. Application of this section will conform to all federal and state regulations concerning the use of radioactive materials.
FEDERAL ACT. Pub. L. No. 92.500, the Federal Water Pollution Control Act, as amended, being 33 U.S.C. §§ 1251 et seq.
GARBAGE. Solid wastes from the domestic and commercial preparation, cooking and dispensing of food, and from the handling, storage and sale of produce.
GREASE AND OILS. A group of substances with similar physical characteristics, including hydrocarbons, fatty acids, soaps, waxes, oils and any other material that is extracted with a stated solvent from an acidified sample and that is not volitized during the test.
HOLDING TANK WASTES. Any waste from holding tanks such as vessels, chemical toilets, campers, trailers, septic tanks and vacuum pump tank trucks.
INCOMPATIBLE POLLUTANT. Any pollutant which is not a “compatible pollutant” as defined in this section.
INDUSTRIAL WASTE SURCHARGE. A charge placed on all users who discharge wastewaters having characteristics in excess of the limits set by this chapter on compatible pollutants.
INDUSTRIAL WASTES. Liquid or water-carried wastes from industrial, commercial and industrial processes and operations, as distinguished from domestic wastes.
MASS EMISSION RATE. The weight of material discharged to the county sewer system during a given time interval. Unless otherwise specified, the MASS EMISSION RATE shall mean pounds per day of a particular constituent or combination of constituents.
pH. The logarithm of the reciprocal of the weight of hydrogen ions in grams per liter of solution.
POLLUTION. An alteration of the quality of the waters of the state by waste to a degree which unreasonably affects the waters for beneficial use or affects the facilities which serve the beneficial uses. POLLUTION may include contamination.
PREMISES. A parcel of real estate or portion thereof including any improvements thereon which is determined by the county to be a single user for purposes of receiving, using and paying for service.
SIGNIFICANT INDUSTRIAL USER. An industry that will contribute greater than 5% of the design flow or designed pollutant loading to the treatment works.
STORM DRAIN or STORM SEWER. A sewer which carries storm or surface waters, but not sewage or industrial wastes.
TOTAL SUSPENDED SOLIDS. The measure of the solids that either float on the surface or are held in suspension in wastes and which are removable from the liquid by laboratory filtering.
TOWN. The Town of Polkton, North Carolina, or any authorized official(s) acting on behalf of the town.
TOWN MAYOR. The Mayor of the Town of Polkton, North Carolina.
TOWN SEWER. A sewer owned and operated by the town, tributary to a treatment facility operated by the county.
TREATMENT WORKS OR PLANT. Any devices and systems used in the storage, treatment, recycling and reclamation of municipal wastewater or industrial wastes of a liquid nature, including interceptor sewers, outfall sewers, wastewater collection systems, pumping, power and other equipment and appurtenances, extensions, improvements, remodeling, additions and alterations thereof; elements essential to provide a reliable recycled supply such as standby treatment units, and clear well storage facilities and any works, including site acquisition of land that will be an integral part of the treatment process or is used for ultimate disposal of residues resulting from the treatment; or any other method or system for preventing, abating, reducing, storing, treating, separating or disposing of municipal wastes, including storm water run-off, or industrial and sanitary sewer systems.
USER CHARGE SYSTEMS. The system developed by EPA that establishes a method for the grant receiving county to recover the costs incurred during planning and construction of a treatment works. USER CHARGE is the charge that users are required to pay for the right to discharge into the sewage system.

WASTEWATER. Wastes and water, whether treated or untreated, discharged into a county sewer.
WASTEWATER CONSTITUENTSAND CHARACTERISTICS. The individual chemical, physical, bacteriological and radiological parameters, including volume and flow rate and other parameters that serve to define, classify or measure the contents, quality and strength of wastewater.
(B) Other terms used in this chapter, but not defined hereinabove, shall have the meanings set forth in the latest edition of Standard Methods for the Examination of Water and Wastewater, published by the American Public Health Association (APHA), the American Waterworks Association (AWWA) and the Water Pollution Control Federation, (WPCF). Unless otherwise expressly stated in this chapter, waste constituents and characteristics shall be measured by methods set forth in the latest edition of Standard Methods for the Examination of Water and Wastewater and/or Methods for Chemical Analysis of Waters and Wastes, published by the Environmental Protection Agency (EPA).
