(expressed as NO2) in excess of the following emission
limits, based on a 30-day rolling average basis, except as provided

(b) The emission limitations under paragraph (a) of this section do
not apply to any affected facility which is combusting coal-derived
liquid fuel and is operating under a commercial demonstration permit
issued by the Administrator in accordance with the provisions of Sec.
60.47Da.
(c) Except as provided under paragraphs (d), (e), and (f) of this
section, when two or more fuels are combusted simultaneously, the
applicable standard is determined by proration using the following
formula:

Where:
[[Page 158]]
En = Applicable standard for NOX when multiple
fuels are combusted simultaneously (ng/J heat input);
w = Percentage of total heat input derived from the combustion of fuels
subject to the 86 ng/J heat input standard;
x = Percentage of total heat input derived from the combustion of fuels
subject to the 130 ng/J heat input standard;
y = Percentage of total heat input derived from the combustion of fuels
subject to the 210 ng/J heat input standard;
z = Percentage of total heat input derived from the combustion of fuels
subject to the 260 ng/J heat input standard; and
v = Percentage of total heat input delivered from the combustion of
fuels subject to the 340 ng/J heat input standard.
(d)(1) On and after the date on which the initial performance test
is completed or required to be completed under Sec. 60.8, whichever
date comes first, no owner or operator of an affected facility that
commenced construction after July 9, 1997, but before or on February 28,
2005 shall cause to be discharged into the atmosphere any gases that
contain NOX (expressed as NO2) in excess of 200
ng/J (1.6 lb/MWh) gross energy output, based on a 30-day rolling average
basis, except as provided under Sec. 60.48Da(k).
(2) On and after the date on which the initial performance test is
completed or required to be completed under Sec. 60.8, whichever date
comes first, no owner or operator of affected facility for which
reconstruction commenced after July 9, 1997, but before or on February
28, 2005 shall cause to be discharged into the atmosphere any gases that
contain NOX (expressed as NO2) in excess of 65 ng/
J (0.15 lb/MMBtu) heat input, based on a 30-day rolling average basis.
(e) Except for an IGCC electric utility steam generating unit
meeting the requirements of paragraph (f) of this section, on and after
the date on which the initial performance test is completed or required
to be completed under Sec. 60.8, whichever date comes first, no owner
or operator of an affected facility that commenced construction,
reconstruction, or modification after February 28, 2005 shall cause to
be discharged into the atmosphere from that affected facility any gases
that contain NOX (expressed as NO2) in excess of
the applicable emission limitation specified in paragraphs (e)(1)
through (3) of this section.
(1) For an affected facility for which construction commenced after
February 28, 2005, the owner or operator shall not cause to be
discharged into the atmosphere any gases that contain NOX
(expressed as NO2) in excess of 130 ng/J (1.0 lb/MWh) gross
energy output on a 30-day rolling average basis, except as provided
under Sec. 60.48Da(k).
(2) For an affected facility for which reconstruction commenced
after February 28, 2005, the owner or operator shall not cause to be
discharged into the atmosphere any gases that contain NOX
(expressed as NO2) in excess of either:
(i) 130 ng/J (1.0 lb/MWh) gross energy output on a 30-day rolling
average basis; or
(ii) 47 ng/J (0.11 lb/MMBtu) heat input on a 30-day rolling average

28, 2005, shall meet the requirements specified in paragraphs (f)(1)
through (3) of this section.
(1) Except as provided for in paragraphs (f)(2) and (3) of this
section, the owner or operator shall not cause to be discharged into the
atmosphere any gases that contain NOX (expressed as
NO2) in excess of 130 ng/J (1.0 lb/MWh) gross energy output
on a 30-day rolling average basis.
(2) When burning liquid fuel exclusively or in combination with

[[Page 159]]
heat input to the combined cycle combustion turbine, the owner or

(3) In cases when during a 30-day rolling average compliance period
liquid fuel is burned in such a manner to meet the conditions in
paragraph (f)(2) of this section for only a portion of the clock hours
in the 30-day period, the owner or operator shall not cause to be
discharged into the atmosphere any gases that contain NOX
(expressed as NO2) in excess of the computed weighted-average
emissions limit based on the proportion of gross energy output (in MWh)
generated during the compliance period for each of emissions limits in
paragraphs (f)(1) and (2) of this section.
