New source.
(1)
Any building, structure, facility, or installation from which
there is (or may be) a discharge of pollutants, the construction of
which commenced after the publication of proposed pretreatment standards
under section 307(c) of the act, which will be applicable to such

with that section, provided that:
(A)
The building, structure, facility, or installation is constructed
at a site at which no other source is located;
(B)
The building, structure, facility, or installation totally replaces
the process or production equipment that causes the discharge of pollutants
at an existing source; or
(C)
The production or wastewater generating processes of the building,
structure, facility, or installation are substantially independent
of an existing source at the same site. In determining whether these
are substantially independent, factors such as the extent to which
the new facility is integrated with the existing plant, and the extent
to which the new facility is engaged in the same general type of activity
as the existing source, should be considered.
(2)
Construction on a site at which an existing source is located results in a modification rather than a new source if the construction does not create a new building, structure, facility, or installation meeting the criteria of subsection
(1)(B) or
(C) above but otherwise alters, replaces, or adds to existing process or production equipment.
(3)
Construction of a new source as defined under this subsection
has commenced if the owner or operator has:

Entered into a binding contractual obligation for the purchase
of facilities or equipment which are intended to be used in its operation
within a reasonable time. Options to purchase or contracts which can
be terminated or modified without substantial loss, and contracts
for feasibility, engineering, and design studies, do not constitute
a contractual obligation under this subsection.

Water used for cooling which does not come into direct contact
with any raw material, intermediate product, waste product, or finished
product.
Pass-through.
A discharge of pollutants through the Town’s wastewater
system into waters of the United States in quantities or concentrations

any discharge requirement of the Town, including an increase in the
magnitude or duration of a violation.

Pretreatment.
The reduction of the amount of pollutants, the elimination
of pollutants, or the alteration of the nature of pollutant properties
in wastewater prior to, or in lieu of, introducing such pollutants
into the POTW. This reduction or alteration can be obtained by physical,
chemical, or biological processes, by process changes, or by other
means, except by diluting the concentration of the pollutants unless
allowed by an applicable pretreatment standard.

imposed on a user, other than a pretreatment standard.

A “treatment works,” as defined by section 212
of the act (33 USC section 1292), which is owned by the Town and/or
the Control Authority. This definition includes any devices or systems

on the basis that it has a reasonable potential for adversely affecting
the POTW’s operation or for violating any pretreatment standard
or requirement; or
(D)
Is defined as subject to National categorical pretreatment standards
by the United States EPA.
(3)
Upon a finding that a user meeting the criteria in subsection
(2) has no reasonable potential for adversely affecting the POTW’s operation or for violating any pretreatment standard or requirement, the Town and/or the Control Authority may at any time, on its own initiative or in response to a petition received from a user, and in accordance with procedures in 40 CFR 403.8(0(6), determine that such user should not be considered a significant industrial user.
