      (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 which will be applicable to the source if the 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;

         (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 divisions (1)(b) and (c) above but otherwise alters, replaces or adds to existing process or production equipment.
      (3)   Construction of a new source as defined in this division has commenced if the owner or operator has begun or caused to begin, as part of a continuous on-site construction program:
