RULE §111.127Monitoring and Recordkeeping Requirements

(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.
