"Part 70 major source or major stationary source" means any
stationary source or group of stationary sources as described in paragraphs
(A), (B) or (C) of this definition. For purposes of paragraphs (B) and (C),
major stationary source includes any group of stationary sources belonging to a
single major industrial grouping that is located on one or more contiguous or
adjacent properties, and that are under common control of the same person (or
persons under common control). For the purposes of defining "major source" in
paragraphs (B) or (C) of this definition, a stationary source or group of
stationary sources shall be considered part of a single industrial grouping if
all of the air pollutant-emitting activities at such source or group of sources
on contiguous or adjacent properties are under common control and belong to the
same Major Group (i. e. , all have the same two-digit code) as described in the
Standard Industrial Classification Manual, 1987. In addition, for purposes of
paragraphs (B) and (C) of this definition, 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 on contiguous
or adjacent properties, shall be considered a support facility and part of the
same source regardless of the 2-digit SIC code for that support facility. A
stationary source (or group of stationary sources) is considered a support
facility to a source if at least fifty percent (50%) of the output of the
support facility is dedicated to the source.
A.
Any major source under Section
112 of the CAA (relating to
hazardous air pollutants), which is defined as follows:
(1) For air pollutants other than
radionuclides, any stationary source or group of stationary sources located
within a contiguous area and under common control that emits or has the
potential to emit considering controls in the aggregate, ten (10) tons per year
(tpy) or more of any single hazardous air pollutant (HAP), (including any
fugitive emissions of such pollutant) which was listed pursuant to Section
112(b) of the CAA,
25 tpy or more of any combination of such HAP (including any fugitive emissions
of such pollutants), or such lesser quantity as the EPA may establish by rule.
Notwithstanding the preceding sentence, 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 such units are in a
contiguous area or under common control, to determine whether such emissions
units or sources are major sources; or
(2) For radionuclides, Part 70 major source
shall have the meaning specified in rules promulgated by the EPA.
B. Any major stationary
source of air pollutants as defined in Section 302 of the CAA that directly
emits or has the potential to emit 100 tpy or more of any single regulated
pollutant excluding GHGs (including any fugitive emissions of any such air
pollutant, as determined by rule by the EPA). 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 or for the
purposes of paragraph (C) of this definition, unless the stationary source
belongs to one of the following categories of stationary sources:
(1) Coal cleaning plants (with thermal
dryers);
(2) Kraft pulp
mills;
(3) Portland cement
plants;
(4) Primary zinc
smelters;
(5) Iron and steel
mills;
(6) Primary aluminum ore
reduction plants;
(7) Primary copper
smelters;
(8) Municipal incinerators
capable of charging more than 50 tons of refuse/day;
(9) Hydrofluoric, sulfuric, or nitric acid
plants;
(10) Petroleum
refineries;
(11) Lime
plants;
(12) Phosphate rock
processing plants;
(13) Coke oven
batteries;
(14) Sulfur recovery
plants;
(15) Carbon black plants
(furnace process);
(16) Primary lead
smelters;
(17) Fuel conversion
plants;
(18) Sintering
plants;
(19) Secondary metal
production plants;
(20) Chemical
process plants;
(21) Fossil-fuel
boilers (or combinations thereof) totaling more than 250 million British
thermal units per hour heat input;
(22) Petroleum storage and transfer units
with a total storage capacity exceeding 300,000 barrels;
(23) Taconite ore processing
plants;
(24) Glass fiber processing
plants;
(25) Charcoal production
plants;
(26) Fossil-fuel-fired steam
electric plants of more than 250 million British thermal units per hour heat
input; or
(27) Any other stationary
source category, which as of August 7, 1980, is being regulated under Section
111 or
112 of the CAA.
C. Any major stationary source as defined in
Part D of Title I of the CAA, including, but not limited to:
(1) For federal ozone nonattainment areas,
except sources for which the EPA has made a finding under Section 182(f)(1) or
(2) of the CAA that requirements under Section 182(f) of the CAA do not apply,
the following sources with the potential to emit:
(a) one hundred (100) tpy or more of nitrogen
oxides (NOx) in areas classified as "marginal" or
"moderate" or in the ozone transport region.
(b) fifty (50) tpy or more of
NOx in areas classified as "serious,"
(c) twenty-five (25) tpy or more of
NOx in areas classified as "severe," and
(d) ten (10) tpy or more of
NOx in areas classified as
"extreme";
(2) For federal
ozone nonattainment areas, the following sources with the potential to emit:
(a) one hundred (100) tpy or more of volatile
organic compounds (VOC) in areas classified as "marginal" or
"moderate,"
(b) fifty (50) tpy or
more of VOC in areas classified as "serious" or in the ozone transport region.
(c) twenty-five (25) tpy or more of
VOC in areas classified as "severe," and
(d) ten (10) tpy or more of VOC in areas
classified as "extreme";
(3) For particulate matter of less than ten
(10) microns (PM10) nonattainment areas, sources with
the potential to emit seventy (70) tpy or more of PM10
in areas that are classified as "serious".
