35 Ill. Adm. Code 204.290
Building, Structure, Facility, or Installation
Section 204.290 Building, Structure, Facility, or
Installation
a) "Building,
structure, facility, or installation" means all of the pollutant-emitting
activities that belong to the same industrial grouping, are located on one or
more contiguous or adjacent properties, and are under the control of the same
person (or persons under common control). Pollutant-emitting activities shall
be considered as part of the same industrial grouping if they belong to the
same "Major Group" (i.e., have the same first two-digit code) as
described in the Standard Industrial Classification Manual (incorporated by
reference in Section 204.100).
b) Notwithstanding
the provisions of subsection (a), building, structure, facility, or
installation means, for onshore activities under Standard Industrial
Classification (SIC) Major Group 13: Oil and Gas Extraction, all of the
pollutant-emitting activities included in Major Group 13 that are located on
one or more contiguous or adjacent properties, and are under the control of the
same person (or persons under common control). Pollutant emitting activities shall
be considered adjacent if they are located on the same surface site, or if they
are located on surface sites that are located within ¼ mile of one another
(measured from the center of the equipment on the surface site) and they share
equipment. Shared equipment includes, but is not limited to, produced fluids
storage tanks, phase separators, natural gas dehydrators or emissions control
devices. Surface site, as used in this subsection, has the same meaning as in
40 CFR 63.761.
