Texas Administrative Code › Title 30 - ENVIRONMENTAL QUALITY › Part 1 - TEXAS COMMISSION ON ENVIRONMENTAL QUALITY › Chapter 115 - CONTROL OF AIR POLLUTION FROM VOLATILE ORGANIC › Subchapter B - GENERAL VOLATILE ORGANIC COMPOUND SOURCES › Division 6 - BATCH PROCESSES › Section 115.166 - Monitoring and Recordkeeping Requirements

Current through Reg. 49, No. 28; July 12, 2024
The owner or operator of each batch process operation in
						the Beaumont/Port Arthur and Houston/ Galveston areas shall maintain the
						following information for at least five years at the plant, as defined by its
						air quality account number, except that the five-year record retention
						requirement does not apply to records generated before December 31, 2000. The
						owner or operator shall make the information available upon request to
						representatives of the executive director, EPA, or any local air pollution
						control agency having jurisdiction in the area:
(1) Vapor control systems. For vapor control
					 systems used to control emissions from batch process operations, records of
					 appropriate parameters to demonstrate compliance, including:
(A) continuous monitoring and recording of:
(i) for a direct-flame incinerator, the
					 exhaust gas temperature in the firebox or in the ductwork immediately
					 downstream of the firebox before any substantial heat exchange. The temperature
					 monitoring device shall have an accuracy of ±0.5 degrees Celsius, or
					 alternatively, ±1.0%;
(ii)
					 for a catalytic incinerator, the exhaust gas temperature immediately before and
					 after the catalyst bed. The temperature monitoring device shall have an
					 accuracy of ±0.5 degrees Celsius, or alternatively,
					 ±1.0%;
(iii) for an
					 absorber, either:
(I) the scrubbing liquid
					 temperature. The temperature monitoring device shall have an accuracy of
					 ±1.0% of the temperature being monitored in degrees Celsius, or
					 alternatively, ±0.02 specific gravity unit; or
(II) the concentration level of volatile
					 organic compounds (VOC) exiting the recovery device based on a detection
					 principle such as infrared, photoionization, or thermal conductivity;
(iv) for a condenser or
					 refrigeration system, either:
(I) the
					 condenser exit temperature. The temperature monitoring device shall have an
					 accuracy of ±1.0% of the temperature being monitored in degrees Celsius,
					 or alternatively, ±0.5 degrees Celsius; or
(II) the concentration level of VOC exiting
					 the recovery device based on a detection principle such as infrared,
					 photoionization, or thermal conductivity;
(v) for a carbon adsorption system, as
					 defined in §
													101.1 of
					 this title (relating to Definitions), either:
(I) steam flow (using an integrating steam
					 flow monitoring device) and the carbon bed temperature. The steam flow monitor
					 shall have an accuracy of ±10%. The temperature monitor shall have an
					 accuracy of ±1.0% of the temperature being monitored in degrees Celsius,
					 or ±0.5 degrees Celsius, whichever is greater; or
(II) the concentration level of VOC exiting
					 the recovery device based on a detection principle such as infrared,
					 photoionization, or thermal conductivity;
(vi) for a pressure swing adsorption unit
					 that is the final recovery device, the temperature of the bed near the inlet
					 and near the outlet. The temperature monitoring device shall have an accuracy
					 of ±1.0% of the temperature being monitored in degrees Celsius, or
					 ±0.5 degrees Celsius; and
(vii) for a vapor combustor, the exhaust gas
					 temperature in the firebox or in the ductwork immediately downstream of the
					 firebox before any substantial heat exchange. The temperature monitoring device
					 shall have an accuracy of ±0.5 degrees Celsius, or alternatively,
					 ±1.0%. Alternatively, the owner or operator of a vapor combustor may
					 consider the unit to be a flare and meet the requirements of subparagraph (B)
					 of this paragraph;
