RACT update
- SFT, Inc., Toledo, OH (United States)
Reasonably Available Control Technology (RACT) is a part of the Clean Air Act Amendments of 1990 (CAAA) Title I, Non-Attainment and in particular Ozone non-attainment. Each state was to have submitted an implementation plan by November 15, 1993 and compliance was scheduled for May 31, 1995. In the early days of the act, states were feverishly writing regulations and deciding on RACT limits. The environmental departments of the states had little information on the ability of existing boiler sources to meet limits and had little information of the application of control technology to existing boilers. The Northeast States Coalition for Air Use Management (NESCAUM) prepared a report with recommended NO{sub x} limits. CIBO recognized that environmental personnel were not getting accurate information concerning the family of industrial and institutional boilers. Because of this lack, CIBO prepared a NO{sub x} RACT GUIDANCE DOCUMENT for the use of environmental regulators and others interested in the application of NO{sub x} control technologies to industrial and institutional boilers. This document explains the difference between industrial boilers and utility boilers. That is important since the regulators had been concentrating on utility boilers and many thought industrial boilers were no different. Test reports from industrial and institutional boilers were solicited and tabled in order to present as much available information as possible concerning NO{sub x} emissions from existing boilers. RACT to meet these limits can be combustion modifications such as low NO{sub x} burners, staged combustion, flue gas recirculation, overfire air, low excess air, burners out of service, or natural gas reburn. Many states considered post combustion processes as RACT such as selective noncatalytic reduction (SNCR) or selective catalytic reduction (SCR). In all cases RACT considered economic impacts.
