On March 21, 2011, the EPA promulgated national emission standards for the control of hazardous air pollutants from two area source categories: industrial boilers, and commercial and institutional boilers. On that same date, the EPA announced that it was convening a proceeding for reconsideration of certain portions of those final emission standards. After promulgation, the Administrator received petitions for reconsideration of certain provisions in the final rule. In this action, the EPA is proposing for reconsideration specific elements and accepting public comment on those elements. We are not requesting comment on any other provisions of the final rule. In this action, the EPA is proposing a limited number of amendments to the final rule. In addition, the EPA is proposing amendments and technical corrections to the final rule to clarify some applicability and implementation issues raised by stakeholders subject to the final rule.

This is a proposed regulation. Comments were due on February 21, 2012.
EPA is proposing national emission standards for control of hazardous air pollutants from two area source categories: Industrial boilers and commercial and institutional boilers. The proposed emission standards for control of mercury emissions from coalfired area source boilers and the proposed emission standards for control of polycyclic organic matter emissions from all area source boilers are based on the maximum achievable control technology. The proposed emission standards for control of mercury emissions from biomass-fired and oilfired area source boilers and for other hazardous air pollutants are based on EPA’s proposed determination as to what constitutes the generally available control technology or management practices.
EPA is also clarifying that gas-fired area source boilers are not needed to meet the 90 percent requirement of section 112(c)(3) of the Clean Air Act. Finally, we are also proposing that existing area source facilities with an affected boiler with a designed heat input capacity of 10 million Btu per hour or greater undergo an energy assessment on the boiler system to identify cost-effective energy conservation measures.
