If applicable, name of local government involved (Article 3.2 and 7.2):     
2. Agency responsible:  Environmental Protection Agency (574) 
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):  Stationary compression 
ignition and spark ignition internal combustion engines (HS 8407.10-90, 8408.10-90; 
ICS 13.040, 27.020) 
5. Title, number of pages and langu age(s) of the notified document:  Standards of 
Performance for Stationary Compression Ign ition and Spark Ignition Internal Combustion 
Engines (24 pages, English)     
6. Description of content:  EPA is proposing revisions to the standards of performance for 
new stationary compression ignition internal combustion engines under section 111(b) of the Clean Air Act. The proposed rule would implement more stringent standards for stationary compression ignition engines with di splacement greater than or equal to 10 litres 
per cylinder and less than 30 litres per cylinder, c onsistent with recent revisions to standards 
for similar mobile source marine engines.  The action also proposes to provide additional 
flexibility to owners and operators of affected engines, and would correct minor mistakes in 
the initial standards of performance.  In a ddition, the action proposes revisions to the 
requirements for engines with displacement at or above 30 litres per cylinder to align more 
closely with recent standards for similar mobile  source marine engines, and for engines in 
rural portions of Alaska that are not accessible by the Federal Aid Highway System.  
Finally, the proposal would make minor revisions to the standards of performance for new stationary spark ignition internal combustion engines to mirror certain revisions proposed 
for compression ignition engines, which woul d provide consistency where appropriate for 
the regulation of stationary internal combus tion engines.  The proposed standards would 
reduce nitrogen oxides by an estimated 1,1 00 tons per year, particulate matter by an 
estimated 38 tons per year, and hydrocarbons by an estimated 18 tons per year by the year 
2030.
