Sec. 60.44  Standard for nitrogen oxides (NOX).

    (a) Except as provided under paragraph (e) of this section, on and 
after the date on which the performance test required to be conducted by 
Sec. 60.8 is

[[Page 140]]

completed, no owner or operator subject to the provisions of this 
subpart shall cause to be discharged into the atmosphere from any 
affected facility any gases that contain NOX, expressed as 
NO2 in excess of:
    (1) 86 ng/J heat input (0.20 lb/MMBtu) derived from gaseous fossil 
fuel.
    (2) 129 ng/J heat input (0.30 lb/MMBtu) derived from liquid fossil 
fuel, liquid fossil fuel and wood residue, or gaseous fossil fuel and 
wood residue.
    (3) 300 ng/J heat input (0.70 lb/MMBtu) derived from solid fossil 
fuel or solid fossil fuel and wood residue (except lignite or a solid 
fossil fuel containing 25 percent, by weight, or more of coal refuse).
    (4) 260 ng/J heat input (0.60 lb MMBtu) derived from lignite or 
lignite and wood residue (except as provided under paragraph (a)(5) of 
this section).
    (5) 340 ng/J heat input (0.80 lb MMBtu) derived from lignite which 
is mined in North Dakota, South Dakota, or Montana and which is burned 
in a cyclone-fired unit.
    (b) Except as provided under paragraphs (c), (d), and (e) of this 
section, when different fossil fuels are burned simultaneously in any 
combination, the applicable standard (in ng/J) is determined by 
proration using the following formula:
[GRAPHIC] [TIFF OMITTED] TR13JN07.001

Where:

PSNOX = Prorated standard for NOX when 
burning different fuels simultaneously, in ng/J heat input derived from 
all fossil fuels fired or from all fossil fuels and wood residue fired;
w = Percentage of total heat input derived from lignite;
x = Percentage of total heat input derived from gaseous fossil fuel;
y = Percentage of total heat input derived from liquid fossil fuel; and
z = Percentage of total heat input derived from solid fossil fuel 
(except lignite).

    (c) When a fossil fuel containing at least 25 percent, by weight, of 
coal refuse is burned in combination with gaseous, liquid, or other 
solid fossil fuel or wood residue, the standard for NOX does 
not apply.
    (d) Except as provided under paragraph (e) of this section, cyclone-
fired units which burn fuels containing at least 25 percent of lignite 
that is mined in North Dakota, South Dakota, or Montana remain subject 
to paragraph (a)(5) of this section regardless of the types of fuel 
combusted in combination with that lignite.
    (e) As an alternate to meeting the requirements of paragraphs (a), 
(b), and (d) of this section, an owner or operator can petition the 
Administrator (in writing) to comply with Sec. 60.44Da(e)(3) of subpart 
Da of this part. If the Administrator grants the petition, the source 
will from then on (unless the unit is modified or reconstructed in the 
future) have to comply with the requirements in Sec. 60.44Da(e)(3) of 
subpart Da of this part.
