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 of production equipment that causes the discharge of pollutants
at an existing source; or
(c)
The production or wastewater-generating processes or the building,
structure, facility or installation are substantially independent
of an existing source at the same site. In determining if 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 shall 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)
For the purpose of this definition, construction of a "new source"
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 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.
