Current through Register Vol. 46, No. 28, July 10, 2024
(a) For
					 emission sources that do not utilize a CEM for compliance monitoring,
					 compliance with the emission limits of section
					 227-2.4  of
					 this Subpart must be determined with a one-hour average except for simple cycle
					 combustion turbines utilized during the non-ozone season. Simple cycle
					 combustion turbines utilized during the non-ozone season may use a 30-day
					 average to determine compliance with the emission limits of section
					 227-2.4  of
					 this Subpart. The owner or operator of each emission source must verify
					 NOx emissions by performing the applicable testing or
					 monitoring procedure detailed below:
(1) For
					 any very large boiler, NOx emissions must be measured
					 with a CEMS as described in subdivision (b) of this section or with an
					 equivalent monitoring system approved by the department.
(2) For any large boiler,
					 NOx emissions must be:
(i) measured in accordance with emission test
					 requirements described in subdivision (c) of this section; or
(ii) monitored with a CEMS as described in
					 subdivision (b) of this section or with an equivalent monitoring system
					 approved by the department.
(3) For any mid-size boiler,
					 NOx emissions must be:
(i) measured in accordance with the emission
					 test requirements described in subdivision (c) of this section; or
(ii) monitored with a CEMS as described in
					 subdivision (b) of this section or with an equivalent monitoring system
					 approved by the department.
(4) For any combined cycle combustion turbine
					 having a maximum heat input rate greater than 250 million Btu per hour,
					 NOx emissions must be measured with a CEMS as described
					 in subdivision (b) of this section.
(5) For any simple cycle, regenerative
					 combustion turbine and any combined cycle combustion turbine having a maximum
					 heat input rate of 250 million Btu per hour or less, NOx
					 emissions must be:
(i) measured in accordance
					 with the emission test requirements described in subdivision (c) of this
					 section; or
(ii) monitored with a
					 CEMS as described in subdivision (b) of this section or with an equivalent
					 monitoring system approved by the department.
(6) For any stationary internal combustion
					 engine, NOx emissions must be:
(i) measured in accordance with the emission
					 test requirements as described in subdivision (c) of this section; or
(ii) monitored with a CEMS as described in
					 subdivision (b) of this section or with an equivalent monitoring system
					 approved by the department.
(7) For any emission source subject to
					 section
					 227-2.4(g) 
					 of this Subpart, NOx emissions must be measured pursuant
					 to a testing, monitoring, and reporting protocol that the department has
					 determined is consistent with the applicable requirements for emission sources
					 regulated under this Subpart that have comparable heat input
					 ratings.
