Section
203.1090  Building, Structure, Facility, or Installation
a)         "Building, structure, facility, or
installation" mean all of the pollutant-emitting activities which 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
203.1000).
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, incorporated by
reference in Section 203.1000, 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.
