(5) For units equipped with CEMS or PEMS, the CEMS
or PEMS must be installed and operational before testing under this
subsection. Verification of operational status must, at a minimum,
include completion of the initial monitor certification and the manufacturer's
written requirements or recommendations for installation, operation,
and calibration of the device.
(6) Initial compliance with §117.2010 of this
title for units operating with CEMS or PEMS must be demonstrated after
monitor certification testing using the NOX CEMS or PEMS.
(7) For units not operating with CEMS or PEMS, the
following apply.
(A) Retesting as specified in paragraphs (1) - (4)
of this subsection is required within 60 days after any modification
that could reasonably be expected to increase the NOX emission rate.
(B) Retesting as specified in paragraphs (1) - (4)
of this subsection may be conducted at the discretion of the owner
or operator after any modification that could reasonably be expected
to decrease the NOX emission rate, including,
but not limited to, installation of post-combustion controls, low-NOX burners, low excess air operation, staged
combustion (for example, overfire air), flue gas recirculation, and
fuel-lean and conventional (fuel-rich) reburn.
(C) The NOX emission rate
determined by the retesting must establish a new emission factor to
be used to calculate actual emissions from the date of the retesting
forward. Until the date of the retesting, the previously determined
emission factor must be used to calculate actual emissions for compliance
with Chapter 101, Subchapter H, Division 3 of this title.
(8) Testing must be performed in accordance with the
schedule specified in §117.9200 of this title.
(9) All test reports must be submitted to the executive
director for review and approval within 60 days after completion of
the testing.
(f) Emission allowances.
(1) For sources that are subject to Chapter 101, Subchapter
H, Division 3 of this title, the NOX testing
and monitoring data of subsections (a) - (e) of this section, together
with the level of activity, as defined in §101.350 of this title
(relating to Definitions), must be used to establish the emission
factor calculating actual emissions for compliance with Chapter 101,
Subchapter H, Division 3 of this title.
(2) The emission factor in subsection (e)(7) of this
section or paragraph (1) of this subsection is multiplied by the unit's
level of activity to determine the unit's actual emissions for compliance
with Chapter 101, Subchapter H, Division 3 of this title.
(g) Run time meters. The owner or operator of any stationary
diesel engine claimed exempt using the exemption of §117.2003(a)(2)(E),
(H), or (I) of this title shall record the operating time with an
elapsed run time meter. Any run time meter installed on or after October
1, 2001, must be non-resettable.
