in compliance with any of the following statutory/regulatory provisions
or permits issued hereunder, or any more stringent state or local
regulations: Section 405 of the Act; the Solid Waste Disposal Act,

body of surface water or groundwater.
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 source
if such standards are thereafter promulgated in accordance with that
section, provided that:
(a)
The building, structure, facility or installation is constructed
at a site at which no other source is located; or
(b)
The building, structure, facility or installation totally replaces
the process or production equipment that causes the discharge or pollutants
at an existing source; or
(c)
The production or wastewater-generating process of the building,
structure, facility, or installation is 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 definition
has commenced if the owner or operator has:
(a)
Begun, or caused to begin, as part of a continuous on-site construction
program, any placement, assembly, or installation of facilities or
equipment; or significant site preparation work, including clearing,
excavation, or removal of existing buildings, structures, or facilities
which is necessary for the placement, assembly, or installation of
new source facilities or equipment; or
(b)
Entered into a building 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 definition.
NONCONTACT COOLING WATER
Water used for cooling which does not come into direct contact
with any raw material, intermediate product, waste product, or finishing
product.
PASS-THROUGH
A discharge which exits the POTW into waters of the United
States in quantities or concentrations which, alone or in conjunction
with other discharge or discharges from other sources, is a cause
of a violation of any requirement of the City of Chicopee's NPDES
permit, including an increase in the magnitude or duration of a violation.
PERSON

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

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.

potential for adversely affecting the POTW's operation or for
violating any pretreatment standard or requirement.
(3)
Upon finding that a user meeting the criteria in Subsection
(2) above has no reasonable potential for adversely affecting the POTW's operations or for violating any pretreatment standard or requirement, the City 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(f)(6), determine that such user should not be considered a significant industrial user.
