FEDERAL GRANT: The U.S. government participation in the financing of the construction of treatment works as provided for by Title II - Grants for Construction of Treatment Works of the Act and implementing regulations.
FLOATABLE OIL: Oil, fat, or grease in a physical state such that it will separate by gravity from wastewater by treatment in an approved pretreatment facility. A wastewater shall be considered free of floatable fat if it is properly pretreated and the wastewater does not interfere with the collection system.

INDUSTRIAL WASTE: Any solid, liquid or gaseous substance discharged, permitted to flow, or escaping from any industrial, manufacturing, commercial or business establishment or process or from the development, recovery or processing of any natural resource as distinct from sanitary sewage.
MAJOR CONTRIBUTING INDUSTRY: The industrial user of the publicly owned treatment works that: a) has a flow of fifty thousand (50,000) gallons or more per average work day; b) has a flow greater than five percent (5%) of the flow carried by the Municipal system receiving the waste; c) has in its waste, a toxic pollutant in toxic amounts as defined in standards issued under section 307(a) of the Act; or d) is found by the permit issuance authority, in connection with the issuance of an NPDES permit to the publicly owned treatment works receiving the waste, to have significant impact, either singly or in combination with other contributing industries, on that treatment works or upon the quality of effluent from that treatment works.
MILLIGRAMS PER LITER: A unit of the concentration of water or wastewater constituent. It is one-thousandth (0.001) g of the constituent in one thousand (1,000) ml of water. It has replaced the unit formerly used commonly, parts per million, to which it is approximately equivalent, in reporting the results of water and wastewater analysis.
NPDES PERMIT: Any permit or equivalent document or requirements issued by the Administrator, or, where appropriate by the Director, after enactment of the Federal Water Pollution Control Amendments of 1972, to regulate the discharge of pollutants pursuant to section 402 of the Act.
NATURAL OUTLET: Any outlet into a watercourse, pond, ditch, lake, or other body of surface or ground water.

PPM: Parts per million by weight.
PERSON: Any individual, firm, company, Municipal or private corporation, association, society, institution, enterprise, governmental agency or other entity.
POPULATION EQUIVALENT: A term used to evaluate the impact of industrial or other waste on a treatment works or stream. One population equivalent is one hundred (100) gallons of sewage per day, containing seventeen one-hundredths (0.17) pounds of BOD and twenty one-hundredths (0.20) pounds of suspended solids. The impact on a treatment works is evaluated as the equivalent of the highest of the three (3) parameters. Impact on a stream is the higher of the BOD and suspended solids parameters.
PRETREATMENT: The treatment of wastewaters from sources before introduction into the wastewater treatment works.
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 (1/2") (1.27 cm) in any dimension.
PUBLIC SEWER: A sewer provided by or subject to the jurisdiction of the City of West Liberty. It shall also include sewers within or outside the City boundaries that serve one or more persons and ultimately discharge into the City sanitary or combined sewer system, even though sewers may not have been constructed with City funds.

The term "operation and maintenance" includes replacement.
SANITARY SEWER: A sewer that conveys sewage or industrial wastes or a combination of both, and into which storm, surface, and ground waters or unpolluted industrial wastes are not intentionally admitted.
SEWAGE: A combination of the water-carried wastes from residences, business buildings, institutions, and industrial establishments, together with such ground, surface, and storm waters as may be present.
