If the industrial user is a corporation, authorized representative
shall mean the president, secretary, treasurer, or a vice president
of the corporation in charge of a principal business function, or
any other person who performs policy or decision-making functions
for the corporation;
2.
If the industrial user is a partnership or sole proprietorship,
authorized representative shall mean a general partner or proprietor,
respectively;

If the industrial user is a Federal, State or local governmental
facility, authorized representative shall mean a Director or the highest
official appointed or designated to oversee the operation and performance
of the activities of the governmental facility, or his designee;
4.
The individuals described in paragraphs (1) through (3) above
may designate another authorized representative if the authorization
is submitted in writing to the Director and the authorization specifies
the individual or position responsible for the overall operation of
the facility from which the discharge originates or who has overall
responsibility for environmental matters for the industrial user.
BATCH
A quantity of wastewater, physically separated from all other
quantities of wastewater, for the purpose of treatment and/or discharge.
BIOCHEMICAL OXYGEN DEMAND (BOD)

of matter under standard laboratory conditions in five (5) days at
twenty degrees Centigrade (20°C), expressed in milligrams per

other place of disposal.
CATEGORICAL PRETREATMENT STANDARD OR CATEGORICAL STANDARD
Any regulation containing pollutant discharge limits promulgated by EPA in accordance with Sections 307(b) and (c) of the Act which apply to a specific category of industrial users and which appear in 40 C.F.R. Chapter
I, Subchapter N, Parts 405-471.

NPDES PERMIT
National Pollutant Discharge Elimination System Permit issued
by the Missouri Department of Natural Resources or EPA.
OIL AND GREASE
Any material recovered as a substance soluble in an organic
extracting solvent as specified by Standard Method 5520 of Standard
Methods of the Examination of Water and Wastewater, 18th Edition,
1992 or the latest revision thereto. Oil and grease is composed primarily
of fatty matter from animal and vegetable sources and from hydrocarbons
of petroleum origin. The concentration of oil and grease of petroleum
hydrocarbon origin can be determined using Standard Method 5520F.
The concentration of oil and grease of animal and vegetable origin
is hereby defined as the difference between the total and the petroleum
hydrocarbon oil and grease concentrations.
