Section 203.1230  Major Stationary Source

a)         The

following constitute a major stationary source:

1)         For an area designated as nonattainment for

ozone, a major stationary source for ozone is a stationary source which emits

or has the potential to emit VOM in an amount equal to or greater than the

following:

A)        100

tpy in an area classified as marginal or moderate nonattainment for ozone;

B)        50 tpy

in an area classified as serious nonattainment for ozone;

C)        25 tpy

in an area classified as severe nonattainment for ozone; and

D)        10 tpy

in an area classified as extreme nonattainment for ozone.

2)         For

an area designated as nonattainment for ozone, a major stationary source for

ozone is a stationary source which emits or has the potential to emit NO

X

in an amount equal to or greater than the following, unless the USEPA has made

a finding under sections 110 and 182(f) of the CAA (42 U.S.C. 7410, 7511a(f))

that controlling of emissions of NO

X

from such source shall not be

required:

A)        100

tpy in an area classified as marginal or moderate nonattainment for ozone;

B)        50 tpy

in an area classified as serious nonattainment for ozone;

C)        25 tpy

in an area classified as severe nonattainment for ozone; and

D)        10 tpy

in an area classified as extreme nonattainment for ozone.

3)         For

an area designated nonattainment for PM

10

, a major stationary source

is a stationary source which emits or has the potential to emit:

A)        100

tpy or more of PM

10

in an area classified as moderate nonattainment

for PM

10

; and

B)        70 tpy

or more of PM

10

in an area classified as serious nonattainment for

PM

10

area classified as extreme nonattainment for ozone.

3)         For

an area designated nonattainment for PM

10

, a major stationary source

is a stationary source which emits or has the potential to emit:

A)        100

tpy or more of PM

10

in an area classified as moderate nonattainment

for PM

10

; and

B)        70 tpy

or more of PM

10

in an area classified as serious nonattainment for

PM

10

.

4)         For

an area designated nonattainment for PM

2.5

, a major stationary

source is a stationary source which emits or has the potential to emit:

A)        100

tpy or more of direct PM

2.5

emissions in an area classified as

moderate nonattainment for PM

2.5

;

B)        100

tpy or more of any individual precursor for PM

2.5

(as required in Section

203.1340) in an area classified as moderate nonattainment for PM

2.5

;

C)        70 tpy

or more of direct PM

2.5

emissions in an area classified as serious

nonattainment for PM

2.5

; and

D)        70 tpy

or more of any individual precursor for PM

2.5

(as required in Section

203.1340), in an area classified as serious nonattainment for PM

2.5

.

5)         For an area designated nonattainment for CO, a

major stationary source is a stationary source which emits or has the potential

to emit:

A)        100

tpy or more in an area classified as moderate nonattainment for CO, except as

provided in subsection (a)(5)(B);

B)        50 tpy

or more in an area classified as serious nonattainment for CO where stationary

sources significantly contribute to ambient CO levels, as determined under

rules issued by the USEPA, under the CAA.

6)         For an area designated as nonattainment for NO

2

,

a major stationary source is a stationary source which emits or has the

potential to emit 100 tpy or more of NO

X

)(B);

B)        50 tpy

or more in an area classified as serious nonattainment for CO where stationary

sources significantly contribute to ambient CO levels, as determined under

rules issued by the USEPA, under the CAA.

6)         For an area designated as nonattainment for NO

2

,

a major stationary source is a stationary source which emits or has the

potential to emit 100 tpy or more of NO

X

.

7)         For

an area designated nonattainment for a pollutant other than those pollutants

addressed in subsections (a)(1) through (a)(6) above, a major stationary source

is a stationary source which emits or has the potential to emit 100 tpy or more

of the pollutant.

8)         For

stationary sources locating outside designated nonattainment areas for purposes

of Subpart R, a major stationary source is a stationary source which emits or

has the potential to emit 100 tpy or more of a regulated NSR pollutant.

b)         Any

physical change that occurs at a stationary source which does not qualify under

subsection (a) as a major stationary source will be considered a major

stationary source, if the change would constitute a major stationary source by

itself.

c)         The fugitive emissions of a stationary source shall

not be included in determining for any purposes of this Section whether it is a

major stationary source, unless the source belongs to one of the following

categories of stationary sources:

1)         Coal

cleaning plants (with thermal dryers);
