(20) Properly shredded garbage means 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 (1.27 centimeters) in any dimension.
(21) Floatable oil means oil, fat or grease in a physical state such that it will separate by gravity from wastewater by treatment in an approved pretreatment facility. Wastewater shall be considered free of floatable fat if it is properly pretreated and the wastewater does not interfere with the collection system.
(22) Population equivalent is a term used to evaluate the impact of industrial or other waste on a treatment works or stream. One population equivalent is 100 gallons of sewage per day, containing .09932 pounds of BOD and 0.1402 pounds of suspended solids.

(24) Industrial waste means 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.
(25) Major contributing industry means an industrial user of the publicly-owned treatment works for which any of the following is true:
A. Has a flow of 50,000 gallons or more per average work day;
B. Has a flow greater than ten percent 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 Federal Act; or
D. Is found by the permit issuing authority, in connection with the issuance of the 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.
