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 § 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;
(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.

(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 division (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 section has commenced if the owner or operator has:
