Sec. 60.73  Emission monitoring.

    (a) The source owner or operator shall install, calibrate, maintain, 
and operate a continuous monitoring system for measuring nitrogen oxides 
(NOX). The pollutant gas mixtures under Performance 
Specification 2 and for calibration checks under Sec. 60.13(d) of this 
part shall be nitrogen dioxide (NO2). The span value shall be 
500 ppm of NO2. Method 7 shall be used for the performance 
evaluations under Sec. 60.13(c). Acceptable alternative methods to 
Method 7 are given in Sec. 60.74(c).
    (b) The owner or operator shall establish a conversion factor for 
the purpose of converting monitoring data into units of the applicable 
standard (kg/metric ton, lb/ton). The conversion factor shall be 
established by measuring emissions with the continuous monitoring system 
concurrent with measuring emissions with the applicable reference method 
tests. Using only that portion of the continuous monitoring emission 
data that represents emission measurements concurrent with the reference 
method test periods, the conversion factor shall be determined by 
dividing the reference method test data averages by the monitoring data 
averages to obtain a ratio expressed in units of the applicable standard 
to units of the monitoring data, i.e., kg/metric ton per ppm (lb/ton per 
ppm). The conversion factor shall be reestablished during any 
performance test under Sec. 60.8 or any continuous monitoring system 
performance evaluation under Sec. 60.13(c).
    (c) The owner or operator shall record the daily production rate and 
hours of operation.
    (d) [Reserved]
    (e) For the purpose of reports required under Sec. 60.7(c), periods 
of excess emissions that shall be reported are defined as any 3-hour 
period during which the average nitrogen oxides emissions (arithmetic 
average of three contiguous 1-hour periods) as measured by a continuous 
monitoring system exceed the standard under Sec. 60.72(a).
