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):  Marine engines for 
recreational and for commercial crafts. 
5. Title, number of pages and language(s) of the notified document:  Draft revision of the 
Lake Constance shipping ordinance (BSO) (14 page s, available in German and French).     
6. Description of content:  The proposed revision of the BSO anticipates the on-going revision 
of the European Community Directives on exha ust gases of engines for Recreational Craft 
94/25/EC and 2003/44/EC (RCD). The "Inter national Navigation Commission for Lake 
Constance" (ISKB) has decided to limit the total amount of exhaust gases produced by an 
engine during an hour of operation to an "E missions Ratio" (ER, see BSO appendix C, 
§ 3.4.3) of 58. This ER primarily limits  the maximum power of propulsion engines of 
recreational craft on Lake Constance.  
A diesel particle filter will be mandatory for di esel engines of more than 37 kW used in any 
kind of new build commercial craft. A “Particle Filter List” published by the Swiss Federal Office for the Environment (FOEN) lists particle filter system types and engine types that fulfil the Swiss Federal Ordinance on Air Pollu tion Control (OAPC) and have been certified 
by a recognised certification bur eau. Institutions that carry out tests and certify the conformity 
of particle filter systems must be accredite d by their national accreditation authority and 
officially recognised by the FOEN. In addition to the listed filters, any diesel engine will be 
accepted (without such a filter) if it does not exce ed the level of particle  emissions set out in 
the UNECE Particle Measurement Programme.   G/TBT/N/CHE/150

  7. Objective and rationale, including the na ture of urgent problems where applicable:  
Environmental protection. The application of cu rrent BSO regulations on the exhaust gases of 
recreational craft has become in creasingly complex in recent years. A revision of the BSO 
was considered necessary.  
The limits set on the particulate emissions for commercial craft are necessary to reduce the 
output of respirable dust. The limits set out for the emission of part iculars of commercial 
crafts is necessary in order to redu ce the output of respirable dust. 
8. Relevant documents:   Lake Constance shipping ordina nce (Bodensee-Schi fffahrts-Ordnung, 
SR 747.223.1) available in German, French, Italian.
