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 (Articles 3.2 and 7.2):         
2. Agency responsible:   Environmental Protection Agency (EPA) (260) 
Name and address (including telephone and fax numbers, e-mail and web-site 
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 applicable, otherwise national tariff heading. 
ICS numbers may be provided in  addition, where applicable):   Locomotive and marine 
engines (HS:  8601, 8602, 8407; ICS:  47.020, 27.020, 13.030). 
5. Title, number of pages and language(s) of the notified document:   Control of Emissions 
of Air Pollution From Locomotive Engines a nd Marine Compression-Ignition Engines Less 
Than 30 Liters per Cylinder; Proposed Rule (215 pages, in English) 
6. Description of content:   The EPA is proposing a comprehensive program to dramatically 
reduce emissions from locomotives and marine di esel engines.  It would apply new exhaust 
emission standards and idle reduction requirements to diesel locomotives of all types -line-haul, switch, and passenger.  It would also set new exhaust emission standards for all types of marine diesel engines below 30 liters per cylinder displacement.  These include marine 
propulsion engines used on vessels from recr eational and small fishing boats to super-
yachts, tugs and Great Lakes freighters, a nd marine auxiliary engines ranging from small 
gensets to large generators on ocean-going v essels.  The proposed program includes near-
term emission standards for newly-built engi nes.  These would phase in starting in 2009. 
The near-term program also contains more stringent emissions standards for existing locomotives.  These would apply when the lo comotive is remanufactured and would take 
effect as soon as certified remanufacture systems are available (as early as 2008), but no 
later than 2010 (2013 for Tier 2 locomotives).  EPA is requesting comments on an alternative under consideration that would apply a similar requirement to existing marine 
diesel engines when they are remanufactured .  EPA is proposing long-term emissions 
standards for newly-built locomotives and marine diesel engines based on the application of 
high-efficiency catalytic after treatment technology.
