APPROVAL AUTHORITY
The Environmental Protection Agency.
AUTHORIZED REPRESENTATIVE OF INDUSTRIAL USER
An authorized representative of an industrial user may be:
A. 
A principal executive officer of at least the level of Vice President, if the industrial user is a corporation.
B. 
A general partner or proprietor if the industrial user is a partnership or proprietorship, respectively.
C. 
A duly authorized representative, as outlined at 40 CFR 403.12(l)(3), of the individual designated above if such representative is responsible for the overall operation of the facilities from which the indirect discharge originates.
BIOCHEMICAL OXYGEN DEMAND (BOD)
The quantity of oxygen utilized in the biochemical oxidation of organic matter under standard laboratory procedure, five days at 20° C., expressed in terms of weight and concentration [milligrams per liter(mg/l)].

BUILDING DRAIN
That part of the lowest horizontal piping of a drainage system, which receives the discharge from soil, waste and other drain drainage pipes inside the walls of the building and conveys it to the building sewer, beginning 10 feet (3.0 meters) outside the inner face of the building wall.
BUILDING SEWER
The extension from the building drain to the public sewer or other place of disposal.
CATEGORICAL STANDARDS
Any regulation containing pollutant discharge limits promulgated by EPA in accordance with Section 307(b) and (c) of the Act (33 U.S.C. § 1317) which apply to a specific category of users and which appear in 40 CFR Chapter I, Subchapter N, Parts 405 through 471.
COMBINED SEWER
A sewer receiving both surface runoff and sewage.
COMPOSITE SAMPLE
A. 
SIMPLE COMPOSITE SAMPLEA timed, sequential collection of equal-volume grab samples collected in a single reservoir.
B. 
FLOW-PROPORTIONED COMPOSITE SAMPLEThe collection of incremental samples with volumes proportional to flow. Influent and effluent operational data shall be obtained through twenty-four-hour flow-proportional composite samples. Sampling may be done manually or automatically, and discretely or continuously. For discrete sampling, at least 12 aliquots shall be composited. Discrete sampling may be flow-proportioned either by varying the time interval between each aliquot or the volume of each aliquot. All composites must be flow-proportional to each stream flow at time of collection of influent aliquot or to the total influent flow since the previous influent aliquot. Volatile pollutant aliquots must be combined in the laboratory immediately before analysis.
CONTROL AUTHORITY
The Director of Public Works.
COOLING WATER
The water discharged from any use such as air conditioning, cooling or refrigeration, or to which the only pollutant added is heat.
DILUTION
The introduction or increase in use of potable, cooling, or process water into the process waste stream. Except where expressly authorized to do so by an applicable categorical pretreatment standard, no industrial user shall ever increase the use of process water or in any other way attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with a categorical pretreatment standard. The control authority (as defined in this section) may impose mass limitations on industrial users which are using dilution to meet applicable pretreatment standards or in other cases where the imposition of mass limitations is appropriate.

Where composite sampling is to obtain influent and effluent operational data, collection of influent grab samples should precede collection of effluent samples by approximately one detention period. The detention period is be based on a twenty-four-hour average daily flow value. The average daily flow used will be based upon the average of the daily flows during the same month of the previous year. Grab samples will be required, for example, where the parameters being evaluated are those such as cyanide and penology, which may not be held for any extended period because of biological, chemical or physical interactions which take place after sample collection and affect the results.[2]
