98.150—Definition of the source category.
The HCFC-22 production and HFC-23 destruction source category consists of HCFC-22 production processes and HFC-23 destruction processes.
(a)
An HCFC-22 production process produces HCFC-22 (chlorodifluoromethane, or CHClF2) from chloroform (CHCl3) and hydrogen fluoride (HF).
(b)
An HFC-23 destruction process is any process in which HFC-23 undergoes destruction. An HFC-23 destruction process may or may not be co-located with an HCFC-22 production process at the same facility.
