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 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 subdivision 1(b) or 1(c) of this definition, 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 user or operator has:
(a) Begun or caused to begin as part of a continuous onsite construction program:
1. Any placement, assembly, or installation of facilities or equipment; or
2. 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 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 subdivision (3).

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 wastewater system. This reduction or alteration can be obtained by physical, chemical, or biological processes, by process changes, or by other means.

(b) Contributes a process wastestream which makes up 5% or more of the average dry weather hydraulic or organic capacity of the wastewater system treatment plant; or
(c) Is designated as such by the town on the basis that it has a reasonable potential for adversely affecting the wastewater system's operation or for violating any pretreatment standard or requirement.
(3) Upon a finding that a user meeting the criteria in division (2) of this definition has no reasonable potential for adversely affecting the wastewater system's operation or for violating any pretreatment standard or requirement, the town 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.
