seq.
The Environmental Protection Agency.
An authorized representative of an industrial user may be:
A principal executive officer of at least the level of Vice
President, if the industrial user is a corporation.
A general partner or proprietor if the industrial user is a
partnership or proprietorship, respectively.

agent or representative of said Board.[1]
That part of the lowest horizontal piping of a drainage system,

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.
The extension from the building drain to the public sewer
or other place of disposal.
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.
A sewer receiving both surface runoff and sewage.
SIMPLE COMPOSITE SAMPLEA timed, sequential collection of equal-volume grab samples collected in a single reservoir.
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.
The Director of Public Works.
The water discharged from any use such as air conditioning,
cooling or refrigeration, or to which the only pollutant added is
heat.
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.
The discharge of treated or untreated wastewater directly
to the waters of the State of Massachusetts.
The Director of Public Works of the Town of Greenfield or
his/her authorized deputy, agent or representative.
That department established by vote of the Town on March
4, 1963, which has jurisdiction over sewerage works and sewage disposal.

appropriate, the term may also be used as a designation for the Administrator
or other duly authorized official of said agency.
Solid wastes from the domestic and commercial preparation,
cooking and dispensing of food and from the handling, storage, and
sale of produce.
An individual sample collected over a period of time not
exceeding 15 minutes. 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]
Any waste from holding tanks such as vessels, chemical toilets,
campers, trailers, septic tanks, and vacuum pump tank trucks.
The discharge or the introduction of any pollutants from
any nondomestic source regulated under Section 307(b) or (c) and (d)
of the Act (33 U.S.C. § 1342) into the POTW (including holding
tank waste discharged into the system).

to adversely affect the POTW's operation or to violate a pretreatment
standard or requirement.
