NEW SOURCE
A.
Any building, structure, facility or installation from which
there is 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:
(1)
The building, structure, facility or installation is constructed
at a site at which no other source is located;
(2)
The building, structure, facility or installation totally replaces
the process or production equipment that causes the discharge of pollutants
at an existing source; or
(3)
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.
B.
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 A(2) or (3) above but otherwise
alters, replaces or adds to existing process or production equipment.
C.
Construction of a new source as defined under this section has
commenced if the owner or operator has:
(1)
Begun, or caused to begin, as part of a continuous on-site construction
program:
(a)

or
(b)

or removal of existing buildings, structures or facilities which is
necessary for the placement, assembly or installation of new source
facilities or equipment; or
(2)
Entered into a binding contractual obligation for the purchase
of facilities or equipment which is 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.

with any raw material, intermediate product, waste product or finished
product.
PASS-THROUGH
A discharge which exits the POTW into waters of the United

with a discharge or discharges from other sources, are a cause of
a violation of any requirement of the City's NPDES permit, including
an increase in the magnitude or duration of a violation.

of pollutants, or the alteration of the nature of pollutant properties
in wastewater prior to, or in lieu of, introducing such pollutants

of the average dry weather hydraulic or organic capacity of the POTW
treatment plant; or
