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) (281) 
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):   Non-road spark-ignition 
engines and equipment  (ICS:  13.020, 13.040) 
5. Title, number of pages and language(s) of the notified document:   Control of Emissions 
from Non-road Spark-Ignition Engines and Equipment; Proposed Rule (297 pages, in 
English). 
6. Description of content:   We are proposing emission standards for new non-road spark-
ignition engines that will substantially reduce emissions from these engines.  The proposed 
exhaust emission standards would apply in 20 09 for new marine spark-ignition engines, 
including first-time EPA standards for stern drive and inboard engines.  The proposed 
exhaust emission standards woul d apply starting in 2011 and 20 12 for different sizes of new 
land-based, spark-ignition engines at or below 19  kilowatts (kW).  These small engines are 
used primarily in lawn and garden appli cations.  We are also proposing evaporative 
emission standards for vessels and equipment us ing any of these engines. In addition, we 
are making other minor amendments to our regul ations.  We estimate that by 2030, the 
proposed standards would result in significant annual reductions of pollutant emissions from 
regulated engine and equipment sources na tionwide, including 631,000 tons of volatile 
organic hydrocarbon emissions, 98,200 tons of  NOX emissions, and 6,300 tons of direct 
particulate matter (PM2.5) emissions.  These re ductions correspond to significant reductions 
in the formation of ground-level ozone.  We also expect to see annual reductions of 
2,690,000 tons of carbon monoxide emissions, w ith the greatest reductions in areas where 
there have been problems with individual exposures.  The requirements in this proposal 
would result in substantial benef its to public health and welf are and the environment.  We 
estimate that by 2030, on an annual basis, these emission reductions would prevent 450 PM-related premature deaths, a pproximately 500 hospitalizations , 52,000 work days lost, and 
other quantifiable benefits every year.  The tota l estimated annual benefits of this rule in 
2030 are approximately $3.4 billion.  Estimate d costs in 2030 are ma ny times less at 
approximately $240 million. G/TBT/N/USA/273
