      (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 (c) above but otherwise alters, replaces, or adds to existing process or production equipment.
      (3)   Construction of a new source as defined under this subdivision has commenced if the owner or operator has:
         (a)   Begun, or caused to begin, as part of a continuous on-site construction program;
