(C) rated at less than 1.0 MW, 0.26 lb/MMBtu;
(11) duct burners used in turbine exhaust ducts, the
corresponding gas turbine emission specification of paragraph (10)
of this subsection;
(12) pulping liquor recovery furnaces, either:
(A) 0.050 lb/MMBtu; or
(B) 1.08 pounds per air-dried ton of pulp;
(13) kilns:
(A) lime kilns, 0.66 pounds per ton of calcium oxide;
and
(B) lightweight aggregate kilns, 1.25 pounds per ton
of product;
(14) metallurgical furnaces:
(A) heat treating furnaces, 0.087 lb/MMBtu; and
(B) reheat furnaces, 0.062 lb/MMBtu;
(15) magnesium chloride fluidized bed dryers, a 90%
reduction from the emission factor used to calculate the 1997 ozone
season daily NOX emissions;
(16) incinerators, either of the following:
(A) an 80% reduction from the emission factor used
to calculate the June - August 1997 daily NOX emissions.
To ensure that this emission specification will result in a real 80%
reduction in actual emissions, a consistent methodology must be used
to calculate the 80% reduction; or
(B) 0.030 lb/MMBtu; and
(17) as an alternative to the emission specifications
in paragraphs (1) - (16) of this subsection for units with an annual
capacity factor of 0.0383 or less, 0.060 lb/MMBtu. For units placed
into service on or before January 1, 1997, the 1997 - 1999 average
annual capacity factor must be used to determine whether the unit
is eligible for the emission specification of this paragraph. For
units placed into service after January 1, 1997, the annual capacity
factor must be calculated from two consecutive years in the first
five years of operation to determine whether the unit is eligible
for the emission specification of this paragraph, using the same two
consecutive years chosen for the activity level baseline. The five-year
period begins at the end of the adjustment period as defined in §101.350
of this title (relating to Definitions).
(b) NOX averaging time.
The averaging time for the emission specifications of subsection (a)
of this section must be as specified in Chapter 101, Subchapter H,
Division 3 of this title, except that electric generating facilities
(EGFs) must also comply with the daily and 30-day system cap emission
limitations of §117.320 of this title (relating to System Cap).
(c) Related emissions. No person shall allow the discharge
into the atmosphere from any unit subject to subsection (a) of this
section, emissions in excess of the following, except as provided
in §117.325 of this title (relating to Alternative Case Specific
Specifications) or paragraph (3) or (4) of this subsection.
(1) CO emissions must not exceed 400 ppmv at 3.0% O2 , dry basis (or alternatively, 3.0 g/hp-hr
for stationary internal combustion engines; or 775 ppmv at 7.0% O2 , dry basis for wood fuel-fired boilers or
process heaters):
(A) on a rolling 24-hour averaging period, for units
equipped with CEMS or PEMS for CO; and
(B) on a one-hour average, for units not equipped with
CEMS or PEMS for CO.
(2) For units that inject urea or ammonia into the
exhaust stream for NOX control, ammonia
emissions must not exceed 10 ppmv at 3.0% O2 ,
dry, for boilers and process heaters; 15% O2 ,
dry, for stationary gas turbines (including duct burners used in turbine
exhaust ducts), gas-fired lean-burn engines, lightweight aggregate
kilns, and diesel engines; 0.0% O2 , dry,
for fluid catalytic cracking units (including CO boilers, CO furnaces,
and catalyst regenerator vents); 7.0% O2 ,
dry, for BIF units that were regulated as existing facilities in 40
CFR Part 266, Subpart H (as was in effect on June 9, 1993), wood-fired
boilers, and incinerators; and 3.0% O2 ,
dry, for all other units, based on:
(A) a block one-hour averaging period for units not
equipped with a CEMS or PEMS for ammonia; or
(B) a rolling 24-hour averaging period for units equipped
with CEMS or PEMS for ammonia.
(3) The correction of CO emissions to 3.0% O2 , dry basis, in paragraph (1) of this subsection
does not apply to the following units:
(A) lightweight aggregate kilns; and
(B) boilers and process heaters operating at less than
10% of maximum load and with stack O2 in
excess of 15% (i.e., hot-standby mode).
(4) The CO limits in paragraph (1) of this subsection
do not apply to the following units:
(A) BIF units that were regulated as existing facilities
in 40 CFR Part 266, Subpart H (as was in effect on June 9, 1993) and
that are subject to subsection (a)(3) of this section; and
(B) incinerators subject to the CO limits of one of
the following:
(i) §111.121 of this title (relating to Single-,
Dual-, and Multiple-Chamber Incinerators);
(ii) §113.2072 of this title (relating to Emission
Limits) for hospital/medical/infectious waste incinerators; or
(iii) 40 CFR Part 264 or 265, Subpart O, for hazardous
waste incinerators.
(d) Compliance flexibility.
(1) Section 117.325 of this title is not an applicable
method of compliance with the NOX emission
specifications of this section.
(2) An owner or operator may petition the executive
director for an alternative to the CO or ammonia specifications of
this section in accordance with §117.325 of this title.
(3) An owner or operator may not use the alternative
methods specified in §§117.315, 117.323, and 117.9800 of
this title (relating to Alternative Plant-Wide Emission Specifications;
Source Cap; and Use of Emission Credits for Compliance) to comply
with the NOX emission specifications
of this section. The owner or operator shall use the mass emissions
cap and trade program in Chapter 101, Subchapter H, Division 3 of
this title to comply with the NOX emission
specifications of this section, except that electric generating facilities
must also comply with the daily and 30-day system cap emission limitations
of §117.320 of this title. An owner or operator may use the alternative
methods specified in §117.9800 of this title for purposes of
complying with §117.320 of this title.
(e) Prohibition of circumvention:
(1) the maximum rated capacity used to determine the
applicability of the emission specifications in subsection (a) of
this section and the initial control plan, compliance demonstration,
monitoring, testing requirements, and final control plan in §§117.335,
117.340, 117.350, and 117.354 of this title (relating to Initial Demonstration
of Compliance; Continuous Demonstration of Compliance; Initial Control
Plan Procedures; and Final Control Plan Procedures for Attainment
Demonstration Emission Specifications) must be:
(A) the greater of the following:
(i) the maximum rated capacity as of December 31, 2000;
or
(ii) the maximum rated capacity after December 31,
2000; or
(B) alternatively, the maximum rated capacity authorized
by a permit issued under Chapter 116 of this title (relating to Control
of Air Pollution by Permits for New Construction or Modification)
on or after January 2, 2001, that the owner or operator submitted
an application determined to be administratively complete by the executive
director before January 2, 2001, provided that the maximum rated capacity
authorized by the permit issued on or after January 2, 2001, is no
less than the maximum rated capacity represented in the permit application
as of January 2, 2001;
(2) a unit's classification is determined by the most
specific classification applicable to the unit as of December 31,
2000. For example, a unit that is classified as a boiler as of December
31, 2000, but subsequently is authorized to operate as a BIF unit,
is classified as a boiler for the purposes of this chapter. In another
example, a unit that is classified as a stationary gas-fired engine
as of December 31, 2000, but subsequently is authorized to operate
as a dual-fuel engine, is classified as a stationary gas-fired engine
for the purposes of this chapter;
(3) changes after December 31, 2000, to a unit subject
to subsection (a) of this section (ESAD unit) that result in increased
NOX emissions from a unit not subject
to subsection (a) of this section (non-ESAD unit), such as redirecting
one or more fuel or waste streams containing chemical-bound nitrogen
to an incinerator with a maximum rated capacity of less than 40 MMBtu/hr
or a flare, is only allowed if:
