(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 § 307(c) of the Act, being 33 U.S.C. § 1317(c), 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;
(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, 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 subsections (1)(b) or (1)(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:
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.
(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 subsection (3)(b).

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 POTW. This reduction of alternation can be obtained by physical, chemical or biological precesses; by process changes; or by other means, except by diluting the concentration of the pollutants unless allowed by an applicable pretreatment standard.

(3) Upon finding that a user meeting the criteria in subsection (2) above has no reasonable potential for adversely affecting the POTW’s operation 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 C.F.R. § 403.8(f)(6), determine that such user should not be considered a significant industrial user.
