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 that 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 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 Section (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:

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 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 definition.

term POTW-TP shall, as the circumstances require, refer to the facility
treating the wastewater and/or the entity responsible for its operation.
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

reasonable potential for adversely affecting the POTW's operation
or for violating any pretreatment standard or requirement.
(3)
The POTW-TP may determine that an industrial user subject to
categorical pretreatment standards is a nonsignificant categorical
industrial user rather than a significant industrial user on a finding
that the industrial user never discharges more than 100 gallons per
day (gpd) of total categorical wastewater (excluding sanitary, noncontact
cooling and boiler blowdown wastewater, unless specifically included
in the pretreatment standard) and the following conditions are met:
(a)
The industrial user, prior to POTW-TP's finding, has consistently
complied with all applicable categorical pretreatment standards and
requirements;
(b)
The industrial user annually submits the certification statement required in §
187-43B of this Part
1 [see 40 CFR 403.12(q)], together with any additional information necessary to support the certification statement; and
(c)
The industrial user never discharges any untreated concentrated
wastewater.
(4)
Upon a finding that a user meeting the criteria in Subsection
(2) of this part has no reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement, the POTW-TP may at any time, on its own initiative or in response to a petition received from an industrial 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.
