| (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.
