NOTIFICATION 
 
The following notification is being circ ulated in accordance with Article 10.6 
 
1. Member to Agreement notifying:  UNITED STATES
  
If applicable, name of local government involved (Article 3.2 and 7.2):     
2. Agency responsible:  Environmental Protection Agency (573) 
Name and address (including telephone and fax numbers, email and website 
addresses, if available) of agency or authority designated to handle comments 
regarding the notification shall be  indicated if different from above :    
3. Notified under Article 2.9.2 [X], 2.10.1 [   ], 5.6.2 [   ], 5.7.1 [   ], other:   
4. Products covered (HS or CCCN where applicab le, otherwise national tariff heading. 
ICS numbers may be provided in  addition, where applicable):  Industrial, commercial, 
and institutional boilers (HS 8402.11-19, 8403.10, 8404.10; ICS 13.040, 27.060)  
5. Title, number of pages and language(s) of the notified document:  National Emission 
Standards for Hazardous Air Pollutants for Area Sources: Industrial, Commercial, and 
Institutional Boilers (41 pages, English).     
6. Description of content:  EPA is proposing national emissi on standards for control of 
hazardous air pollutants from two area source cat egories: Industrial boilers and commercial 
and institutional boilers.  The proposed emission standards for control of mercury emissions 
from coal-fired area source boilers and the pr oposed 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 oil-fired ar ea source boilers and for other hazardous air 
pollutants are based on EPA's proposed determ ination as to what constitutes the generally 
available control technology or management practices.  
EPA is also clarifying that gas-fired area s ource 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. 
We will hold a public hearing concerning this proposed rule and the interrelated proposed 
Boiler major source, CISWI, and RCRA rules, discussed in this proposal and published in 
the proposed rules section of today's Federal Register, on 21 June 2010 .  Persons requesting 
to speak at a public hearing must contact EPA by 14 June 2010. 
Under the Paperwork Reduction Act, comment s 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/555
