as described in the Standard Industrial Classification Manual, 1987*. For
purposes of clauses (B) and (C), any stationary source (or group of stationary
sources) that supports another source, where both are under common control of
the same person (or persons under common control) and are located on contiguous
or adjacent properties, shall be considered a support facility and part of the
same source regardless of the two (2) digit SIC code for that support facility.

any HAP that has been listed in Section 112(b) of the CAA ;
(BB) twenty-five (25) tpy or more of any
combination of such HAPs; or

(AA) emissions from any oil or gas
exploration or production well (with its associated equipment) and emissions
from any pipeline compressor or pump station shall not be aggregated with
emissions from other similar units, whether or not the units are in a
contiguous area or under common control, to determine whether the units or
stations are major sources; and
(BB) research and development activities may
be considered separately for purposes of determining whether a major source is
present and need not be aggregated with collocated stationary sources unless
the research and development activities contribute to the product produced or
service rendered by the collocated sources in a more than de minimis
manner.
(iii) For
radionuclides, major source shall have the meaning specified by the U.S. EPA by
rule.
(B) A major
stationary source of air pollutants, as defined in Section 302 of the CAA , that
directly emits or has the potential to emit , one hundred (100) tpy or more of
any air pollutant subject to regulation (including any major source of fugitive
emissions of any such pollutant, as determined by the U.S. EPA by rule). The
fugitive emissions of a stationary source shall not be considered in
determining whether it is a major stationary source for the purposes of Section
302(j) of the CAA unless the source belongs to one (1) of the following
