into the atmosphere from any unit subject to NOX emission
specifications in subsection (a) of this section, emissions in excess
of the following, except as provided in §117.425 of this title
(relating to Alternative Case Specific Specifications) or paragraph
(3) or (4) of this subsection.

does not apply to 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).

director for an alternative to the CO or ammonia specifications of
this section in accordance with §117.425 of this title.
(e) Prohibition of circumvention.
(1) The maximum rated capacity used to determine the
applicability of the emission specifications in this section and the
initial compliance demonstration, monitoring, testing requirements,
and final control plan in §§117.435, 117.440, and 117.454
of this title (relating to Initial Demonstration of Compliance; Continuous
Demonstration of Compliance; and Final Control Plan Procedures for
Attainment Demonstration Emission Specifications) must be the greater
of the following:
(A) the maximum rated capacity as of December 31, 2000;
(B) the maximum rated capacity after December 31, 2000;
or
(C) 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) after December
31, 2000.
(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 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.
