Current through Reg. 49, No. 28; July 12, 2024
(a) Except for incinerators which can qualify
					 for a permit by rule found in §
											106.491
					 of this title (relating to Dual Chamber Incinerators), or §
											106.494
					 of this title (relating to Pathological Waste Incinerators), incinerators
					 burning more than 100 pounds per hour of waste as specified in §
											111.121
					 of this title (relating to Single-, Dual-, and Multiple-Chamber Incinerators)
					 shall install, calibrate, maintain, and operate a monitoring device that
					 continuously measures and records the oxygen (O2) content and temperature of
					 the exhaust gas of the incinerator. Incinerators which qualify for a permit by
					 rule in §
											106.491
					 or §
											106.494
					 of this title, and which burn more than 100 pounds per hour, shall install,
					 calibrate, maintain, and operate a monitoring device that continuously measures
					 and records the temperature of the exhaust gas of the incinerator. The
					 monitoring device for incinerators equipped with a wet scrubbing device shall
					 continuously measure and record the pressure drop of the gas flow through the
					 wet scrubbing device. Except for incinerators which can qualify for a permit by
					 rule found in §
											106.491
					 or §
											106.494
					 of this title, incinerators burning more than 225 pounds per hour of domestic,
					 municipal, commercial, or industrial solid waste shall be equipped with
					 continuous emissions monitors which measure and record in-stack carbon monoxide
					 (CO) in addition to the other requirements of this section. A total hydrocarbon
					 (THC) monitor may be substituted for the CO monitor if a THC standard is
					 established in accordance with §
											111.121(3)
					 of this title. For municipal incinerators built prior to 1990 and burning less
					 than 2,000 pounds per hour of municipal solid waste, a stack test for CO may be
					 performed to establish O2 and temperature requirements necessary to maintain
					 minimum CO emissions, and monitoring of these parameters may be substituted for
					 the CO monitoring device. The O 2, THC, and CO monitoring devices described in
					 this section must be certified for use following procedures outlined in 40 Code
					 of Federal Regulations (CFR) 60, Appendix B, Performance Specifications 3 and
					 4, respectively. Such certification must be approved by the executive director
					 or a designated representative of the Texas Natural Resource Conservation
					 Commission (TNRCC). Compliance determinations may be made based on results of
					 monitoring with a certified monitor. Compliance with the CO and/or THC
					 requirements specified in §
											111.121(3)
					 of this title and §
											111.124(4)
					 of this title (relating to Burning Hazardous Waste Fuels in Commercial
					 Combustion Facilities) may be demonstrated using a rolling hourly average. The
					 rolling hourly average shall be defined as the arithmetic mean of the 60 most
					 recent one-minute concentrations measured by the continuous monitoring
					 system.
(b) The owner or operator
					 of an incinerator or commercial combustion facility subject to the requirements
					 of §§
											111.121,
					 111.124,
					 and
					 111.125 of
					 this title (relating to Single-, Dual-, and Multiple-Chamber Incinerators;
					 Burning Hazardous Waste Fuels in Commercial Combustion Facilities; and Testing
					 Requirements), respectively, shall maintain written records of all monitoring
					 and testing results, hours of operation, and quantity of waste burned. Such
					 records shall be retained for a period of not less than two years before being
					 destroyed. Such records shall be made available upon request by authorized
					 representatives of the TNRCC, United States Environmental Protection Agency
					 (EPA), or local air pollution control agencies. Alternately, for facilities
					 other than commercial combustion facilities, in the absence of records
					 verifying waste quantities burned, the design capacity of the unit will be used
					 to determine applicable controls.
(c) The owner or operator of a commercial
					 combustion facility subject to the requirements of §
											111.124
					 of this title shall install, calibrate, maintain, and operate a monitoring
					 device that continuously measures and records the waste feed rate, combustion
					 gas velocity, opacity, O2 content, CO content, THC content, and temperature of
					 the exhaust gas of the combustion device. CO and THC shall be corrected to 7.0%
					 O2, reported on a dry basis, and measured in the same location. The O2, THC,
					 CO, combustion gas velocity, and opacity devices must be certified for use
					 following procedures outlined in 40 CFR Part 60. Such certification must be
					 approved by the executive director or his designated representative of the
					 TNRCC. Compliance determinations may be made based on results of monitoring
					 with a certified monitor.
(d) Upon
					 the request of the executive director or a designated representative of the
					 TNRCC, EPA, or local air pollution control agency, the owner or operator of an
					 incinerator which is exempt from the requirements specified in §
											111.121
					 of this title and whose incinerator has the capacity to burn more than 100
					 pounds per hour shall maintain written records of the amount of waste burned.
					 Such records shall be retained for a period of not less than two years before
					 being destroyed.
