New MACT for Boilers Under Development
A Maximum Achievable Control Technology (MACT) standard will be proposed in November 1999 for industrial combustion sources, including boilers, process heaters, stationary turbines, and stationary internal combustion engines. The standard will be promulgated in November 2000.
Through a coordinating committee of stakeholder representatives and several work groups, the Industrial Combustion Coordinated Rulemaking (ICCR) Committee will develop recommendations for the various combustion source categories and pollutants (hazardous air pollutants and criteria pollutants).
Recently, the Pollution Prevention Subgroup recommended several "Good Combustion Practices" for consideration by the Coordinating Committee. Some of these recommendations include: official documented operating and maintenance procedures; monitor fuel/waste quality; continuous or periodic monitoring to adjust air distribution and fuel/waste dispersion; and procedures in place to ensure adequate atomization and mixing with combustion air. These recommendations identify possible ways the work groups could incorporate requirements for good combustion practices into regulatory recommendations. However, they may not be applicable to all combustion sources and will require evaluation by the different source work groups.

MACT Standards Proposed
The EPAs Office of Air Quality Planning and Standards is continuing to develop new Maximum Achievable Control Technology (MACT) standards for several source categories. MACT is required by Title III of the 1990 Clean Air Act and is based on maximum available control technology for major sources of hazardous air pollutants.
The table to the right is a partial list of affected source categories and their corresponding promulgation dates. For additional information, contact Joelle Burleson, N.C. Division of Air Quality, at (919) 733-1474. For a complete listing of MACTs, consult EPAs web page.
