of which commenced after the publication of proposed pretreatment
standards under 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

is engaged in the same general type of activity as the existing source,
should be considered; or
