flow rate or 10 standard cubic feet per minute, whichever is greater.
(3) Ensure the heat-sensing CPMS
indicates the presence of the pilot flame while emissions are routed to the
control device. Heat-sensing CPMS are exempt from the calibration, quality
assurance and quality control requirements in this section.
(4) Ensure the temperature CPMS has a minimum
accuracy of ±1% of the temperature being monitored in °Celsius
(±1.8% in °Fahrenheit) or ±2.5 °Celsius (±4.5
°Fahrenheit), whichever value is greater.
(5) Ensure the organic concentration CPMS
meets the requirements of Performance Specification 8 or 9 of 40 CFR Part 60,
Appendix B (relating to performance specifications).
(6) Establish the operating parameter value
to define the conditions at which the control device must be operated to
continuously achieve the applicable performance requirement as follows:
(i) For a parameter value established while
conducting a performance test under subsection (k) or subsection (l):
(A) Base each minimum operating parameter
value on the value established while conducting the performance test and
supplemented, as necessary, by the design analysis of subsection (g)(6),
subsection (h)(2) or subsection (i)(7), the manufacturer's recommendations, or
both.
(B) Base each maximum
operating parameter value on the value established while conducting the
performance test and supplemented, as necessary, by the design analysis of
subsection (g)(6), subsection (h)(2) or subsection (i)(7), the manufacturer's
recommendations, or both.
(ii) Except as specified in clause (C), for a
parameter value established using a design analysis in subsection (g)(6),
subsection (h)(2) or subsection (i)(7):
(A)
Base each minimum operating parameter value on the value established in the
design analysis and supplemented, as necessary, by the manufacturer's
recommendations.
(B) Base each
maximum operating parameter value on the value established in the design
analysis and supplemented, as necessary, by the manufacturer's
recommendations.
(C) If the owner
or operator and the Department do not agree on a demonstration of control
device performance using a design analysis as specified in clause (A) or (B),
then the owner or operator shall perform a performance test under subsection
(k) or subsection (l) to resolve the disagreement. The Department may choose to
have an authorized representative observe the performance test.
(iii) For a condenser, establish a
condenser performance curve showing the relationship between condenser outlet
temperature and condenser control efficiency that demonstrates the condenser
complies with the applicable performance requirements in subsection (i)(1) as
follows:
(A) Based on the value measured
while conducting a performance test under subsection (k) or subsection (l) and
supplemented, as necessary, by a condenser design analysis performed under
subsection (i)(7), the manufacturer's recommendations, or both.
(B) Based on the value from a condenser
design analysis performed under subsection (i)(7) supplemented, as necessary,
by the manufacturer's recommendations.
(7) Except for the CPMS in paragraphs (2) and
(3), calculate the daily average for each monitored parameter for each
operating day using the data recorded by the CPMS. Valid data points must be
available for 75% of the operating hours in an operating day to compute the
daily average where the operating day is:
(i)
A 24-hour period if the control device operation is continuous.
(ii) The total number of hours of control
device operation per 24-hour period.
(8) Except as specified in subparagraph
(iii), do both of the following:
(i) Ensure
the data recorded by the CPMS is used to assess the operation of the control
device and associated control system.
(ii) Report the failure to collect the
required data in paragraph (1) as a deviation of the monitoring
requirements.
(iii) The
requirements of subparagraphs (i) and (ii) do not apply during:
(A) A monitoring system
malfunction.
(B) A repair
associated with a monitoring system malfunction.
(C) A required monitoring system quality
assurance or quality control activity.
(9) Determine compliance with the established
parameter value by comparing the calculated daily average to the established
operating parameter value as follows:
(i) For
a minimum operating parameter established in paragraph (6)(i)(A) or paragraph
(6)(ii)(A), the control device is in compliance if the calculated value is
equal to or greater than the established value.
(ii) For a maximum operating parameter
established in paragraph (6)(i)(B) or paragraph (6)(ii)(B), the control device
is in compliance if the calculated value is less than or equal to the
established value.
