  "definition": "1. Any apparatus that reduces the quantity of a pollutant emitted to the air. [40 CFR 60.711 (CFR 2013)] [40 CFR 60.741 (CFR 2013)]This is a basic definition. Other more specific definitions for devices removing particulate matter are at [40 CFR 60.731 (CFR 2013)][40 CFR 60.261 (CFR 2013)][40 CFR 60.271 (CFR 2013)][40 CFR 60.381 (CFR 2013)] [40 CFR 63.10692 (CFR 2013)][40 CFR 60.271a (CFR 2013)][40 CFR 60.671 (CFR 2013)][40 CFR 63.11532 (CFR 2013)][40 CFR 63.10906 (CFR 2013)][40 CFR 63.11151 (CFR 2013)]\n\n2. Equipment, other than inherent process equipment, that is used to destroy or remove air pollutant(s) prior to discharge to the atmosphere.\n\n3. Device such as a carbon adsorber or oxidizer which reduces the organic HAP in an exhaust gas by recovery or by destruction. [40 CFR 63.822 (CFR 2013)] This is a basic definition. Other more specific definitions for devices which reduce exhausted organic HAP are here. [40 CFR 63.3310 (CFR 2013)][40 CFR 63.1251 (CFR 2013)][40 CFR 63.1361 (CFR 2013)] [40 CFR 63.1271 (CFR 2013)][40 CFR 63.761 (CFR 2013)]\n\n4. Any combustion device, recovery device, or recapture device. Such equipment includes, but is not limited to, absorbers, carbon adsorbers, condensers, incinerators, flares, boilers, and process heaters. For continuous process vents, recapture devices are considered control devices but recovery devices are not considered control devices. Condensers operating as process condensers are not considered control devices. For a condenser that sometimes operates as a process condenser to be considered a control device, it shall not be operating as a process condenser for a given batch emission episode, and it shall recycle of the recovered material within the process.\n\n5. Destruction and/or recovery equipment used to destroy or recover HAP or VOC emissions generated by a regulated operation. [40 CFR 63.742 (CFR 2013)]]\n\n6. Enclosed combustion device, vapor recovery system, or flare. [40 CFR 60.481 (CFR 2013)] [40 CFR 60.481a (CFR 2013)] [40 CFR 60.561 (CFR 2013)] [40 CFR 60.691 (CFR 2013)]\n\n7. Any combustion device, recovery device, recapture device, or any combination of these devices used to comply with this subpart. Such equipment or devices include, but are not limited to, absorbers, adsorbers, condensers, and combustion devices. Primary condensers, steam strippers, and fuel gas systems are not considered control devices. [40 CFR 63.2406 (CFR 2013)]\n\n8. Any equipment that reduces the quantity of a pollutant that is emitted to the air. The device may destroy or secure the pollutant for subsequent recovery. Includes, but is not limited to, incinerators, carbon adsorbers, and condensers.\n\n9. For purposes of this § 63.1255, means any equipment used for recovering or oxidizing organic hazardous air pollutant vapors. Such equipment includes, but is not limited to, absorbers, carbon adsorbers, condensers, flares, boilers, and process heaters.\n\n10. With the exceptions noted below, a combustion device, recovery device, recapture device, or any combination of these devices used to comply with this subpart or a referencing subpart. For process vents from continuous unit operations at affected sources in source categories where the applicability criteria includes a TRE index value, recovery devices are not considered to be control devices. Primary condensers on steam strippers or fuel gas systems are not considered to be control devices. [40 CFR 63.1082 (CFR 2013)][40 CFR 63.1101 (CFR 2013)]\n\n11. Any equipment used for recovering, removing, or oxidizing HAP in either gaseous or solid form. Such equipment includes, but is not limited to, condensers, scrubbers, electrostatic precipitators, incinerators, flares, boilers, and process heaters.\n\n12. Defined in § 63.111, except that the term “continuous process vents subject to § 63.1315” shall apply instead of the term “process vents,” for the purpose of this subpart.\n\n13. With the exceptions noted in this definition, a combustion device, recovery device, recapture device or any combination of these devices used to comply with this subpart. Process condensers are not control devices.\n\n14. Equipment, other than inherent process equipment, that is used to destroy or remove air pollutant(s) prior to discharge to the atmosphere. The types of equipment that may commonly be used as control devices include, but are not limited to, fabric filters, mechanical collectors, electrostatic precipitators, inertial separators, afterburners, thermal or catalytic incinerators, adsorption devices (such as carbon beds), condensers, scrubbers (such as wet collection and gas absorption devices), selective catalytic or non-catalytic reduction systems, flue gas recirculation systems, spray dryers, spray towers, mist eliminators, acid plants, sulfur recovery plants, injection systems (such as water, steam, ammonia, sorbent or limestone injection), and combustion devices independent of the particular process being conducted at an emissions unit (e.g., the destruction of emissions achieved by venting process emission streams to flares, boilers or process heaters). For purposes of this part, a control device does not include passive control measures that act to prevent pollutants from forming, such as the use of seals, lids, or roofs to prevent the release of pollutants, use of low-polluting fuel or feedstocks, or the use of combustion or other process design features or characteristics. If an applicable requirement establishes that particular equipment which otherwise meets this definition of a control device does not constitute a control device as applied to a particular pollutant-specific emissions unit, then that definition shall be binding for purposes of this part.\n\n15. Defined in § 63.111, except that the term “continuous front-end process vent” shall apply instead of the term “process vent,” for the purpose of this subpart.",
