5. Title, number of pages and language(s) of the notified document:   Draft revision of the 
Ordinance on Air Pollution Control (OAPC, Amendment of 1 July 2007.) (13 pages, in German, French and Italian) 
6. Description of content :  Measures to combat particulates: tighter limit values for wood- 
and coal-fired systems and further adaptations in this context:  
• Wood-fired systems with a thermal output up to 350 kW may only be introduced if they 
can be shown to be in conformity with th e corresponding EU product standards and that 
they meet modern air pollution control requirements. 
• Automatic wood-fired systems with a therma l output in excess of 70kW must be fitted 
with effective particulate traps such as elect rostatic dust precipitators or fibre filters. 
The new particulate limit values will be in troduced progressively according to the size 
of the installation (2007 to 2015). 
• The general total particulate emission limit value of 50 mg/m3 will be reduced to 20 
mg/m3 (analogous to the TA Luft in Germany). G/TBT/N/CHE/81

basis. The particulate limit value for various equipment will be adapted to state of the art 
requirements.
