A. Continuous emission monitors (CEM)s shall be installed, calibrated, maintained, and operated, and shall continuously record data for the following:

(1) For PWDs with a total charging rate of 1000 pounds per hour or greater: (a) carbon monoxide (CO); (b) oxygen (O2); (c) opacity.

(2) If an opacity monitor cannot be applied satisfactorily, alternate apparatus may be employed, on a case by case basis, with the written approval of the department to demonstrate acceptable operation of the particulate removal device.

(3) For PWDs with a total charging capacity of less than 1000 pounds per hour (a) oxygen (O2); (b) carbon monoxide (CO).

B. The owner or operator of any unit shall install, calibrate, maintain and operate equipment to continuously record the temperature of gases leaving the primary and secondary combustion chambers and the outlet of the final air pollution control device, if present. Such equipment shall have an accuracy of plus or minus 0.75 percent of the temperature being measured expressed in degrees Celsius or plus or minus 2.5 degrees C, whichever represents greater accuracy. Sensors shall be located so that flames from the burners do not impinge on the sensors.

C. At least ninety days prior to initial startup, the owner or operator shall submit a report the department which describes, for each monitor, the location, specifications, calibration procedures, operation, maintenance, data evaluation, and reporting. Monitoring equipment shall not be installed prior to department approval of the report.

D. The continuous emission monitors for oxygen (O2) and carbon monoxide (CO) shall complete a minimum of one operation cycle for each successive 15-minute period. One-hour averages shall be calculated from four (4) or more data points equally spaced over each one-hour period.

E. The continuous opacity monitor shall complete a minimum of one operational cycle for each successive ten-second period. Six-minute averages shall be calculated from thirty-six or more data points equally spaced over each six-minute period.

F. Data recorded during periods of continuous emission monitor breakdown; repairs, calibration checks, and zero and span adjustments shall...
