5. Title, number of pages and language(s) of the notified document:  National Emission 
Standards for Hazardous Air Pollutants for Major Sources: Industrial, Commercial, and 
Institutional Boilers and Process Heaters (69 pages, English).     
6. Description of content:  On 13 September 2004, under authority of section 112 of the 
Clean Air Act, EPA promulgated national em ission standards for hazardous air pollutants 
for new and existing industrial/commercial/institu tional boilers and process heaters.  On 19 
June 2007, the United States Court of Appeals fo r the District of Columbia Circuit vacated 
and remanded the national emission sta ndards for hazardous air pollutants for 
industrial/commercial/institutional boilers and process heaters.  
In response to the court's vacatur and remand, this action would require all major sources to 
meet hazardous air pollutants emissions st andards reflecting the application of the 
maximum achievable control technology.  Th e proposed rule would protect air quality and 
promote public health by reducing emissions of  the hazardous air pollutants listed in section 
112(b)(1) of the Clean Air Act. 
We are also proposing that existing major s ource facilities with an affected boiler undergo 
an energy assessment on the boiler system to identify cost-effective energy conservation 
measures. We will hold a public hearing concerni ng this proposed rule and the interrelated 
proposed Boiler area source, CISWI, and RCRA  rules, discussed in this proposal and 
published in the proposed rules section of toda y's Federal Register, on 21 June 2010.  
Persons requesting to speak at a public heari ng must contact EPA by 14 June 2010.  Under 
the Paperwork Reduction Act, comments on the information collection provisions are best 
assured of having full effect if the Office of Management and Budget (OMB) receives a copy of your comments on or before 6 July 2010. G/TBT/N/USA/554
