Section 326IAC8-19-6. Monitoring requirements

   (a) Every owner or operator using an incinerator to comply with section 3 of this rule shall install, calibrate, maintain, and operate, according to manufacturer's specifications, temperature monitoring devices with an accuracy of plus or minus one percent (1%) of the temperature being measured expressed in degrees Celsius or plus or minus one and eight-tenths percent (1.8%) of the temperature being measured expressed in degrees Fahrenheit, each equipped with a continuous recorder as follows:

(1) Where a catalytic incinerator is used, temperature monitoring devices shall be installed in the gas stream immediately before and after the catalyst bed.

(2) Where an incinerator other than a catalytic incinerator is used, a temperature monitoring device shall be installed in the combustion chamber.

  (b) The owner or operator using a flare to comply with section 3 of this rule shall install, calibrate, maintain, and operate, according to manufacturer's specifications, a heat sensing device, such as an ultraviolet beam sensor or thermocouple, at the pilot light to indicate continuous presence of a flame.

  (c) Every owner or operator using a scrubber to comply with section 3 of this rule shall install, calibrate, maintain, and operate, according to manufacturer's specifications:

(1) a temperature monitoring device for scrubbant liquid having an accuracy of plus or minus one percent (1%) of the temperature being monitored expressed in degrees Celsius or plus or minus one and eight-tenths percent (1.8%) of the temperature being measured expressed in degrees Fahrenheit and a specific gravity device for scrubbant liquid, each equipped with a continuous recorder; or

(2) a VOC monitoring device used to indicate the concentration of VOC exiting the control device based on a detection principle, such as infrared, photoionization, or thermal conductivity, equipped with a continuous recorder.

  (d) Every owner or operator using a condenser to comply with section 3 of this rule shall install, calibrate, maintain, and operate, according to manufacturer's specifications:

(1) a condenser exit temperature monitoring device equipped with a continuous recorder and having an accuracy of plus or minus one percent (1%) of the temperature being monitored expressed in degrees Celsius or plus or minus one and eight-tenths percent (1.8%) of the temperature being measured expressed in degrees Fahrenheit, equipped with a continuous recorder; or

(2) a VOC monitoring device used to indicate the concentration of VOC, such as infrared, photoionization, or thermal conductivity, each equipped with a continuous recorder.

  (e) Every owner or operator using a carbon adsorber to comply with section 3 of this rule shall install, calibrate, maintain, and operate, according to the manufacturer's specifications:

(1) an integrating regeneration steam flow monitoring device having an accuracy of plus or minus ten percent (10%), and a carbon bed temperature monitoring device having an accuracy of plus or minus one percent (1%) of the temperature being monitored expressed in degrees Celsius or plus or minus one and eight-tenths percent (1.8%) of the temperature being measured expressed in degrees Fahrenheit, both equipped with a continuous recorder; or

(2) a VOC monitoring device used to indicate the concentration level of VOC exiting the device based on a detection principle, such as infrared, photoionization, or thermal conductivity, equipped with a continuous recorder.

  (f) Every owner or operator using a boiler or process heater with a design heat input capacity less than one hundred fifty million (150,000,000) Btu per hour that is to comply with section 3 of this rule shall install, calibrate, maintain, and operate, according to the manufacturer's specifications, a temperature monitoring device in the firebox with an accuracy of plus or minus one percent (1%) of the temperature being measured expressed in degrees Celsius or plus or minus one and eight-tenths percent (1.8%) of the temperature being measured expressed in degrees Fahrenheit, equipped with a continuous recorder. Any boiler or process heater in which all process vent streams are introduced with primary fuel is exempt from this requirement.

  (g) Every owner or operator of a process vent shall be permitted to monitor by an alternative method or may monitor parameters other than those listed in subsections (a) through (f), if approved by the commissioner and U.S. EPA in writing. The alternative method or parameters shall be contained in a permit pertaining to the process vent as federally enforceable permit conditions.
