Legal basis for diesel particulate filters

Germany

In general Germany, as a member of the European Community (EC), has to fulfil the restrictions coming along the fine dust regulation. In doing so several different concepts were followed: ban of driving for vehicles without particle filter, establishing vehicle free zones in the city centres, city fee, or usage of particle filters on vehicles near construction sites or on municipal vehicles, inside city areas. The usage of particle filters has the advantage of fighting against the emissions were they really arise, it does not limit the mobility of the citizens and is not lowering the attractiveness of the city centres for tourists and consumption oriented citizens.

A lot of cities recognised this and have retro-fit the vehicles for municipal purposes (e.g. garbage collectors) as well as the vehicles for public transportation (e.g. buses) with particulate filters. On construction sites nearby the city centre more and more often construction machines need to be equipped with particulate filters, too.

Older than the EC fine dust regulation is the TRGS-554 (regulation for the treatment of harmful substances) today valid in the version of 2001. This regulation is restricting the emissions of diesel driven equipment in capsuled areas like halls, tunnels and mines. Section 4 of the TRGS-554 is listing a number of security measures against emissions from diesel engines. The diesel particulate filter is named as an effective measure against diesel particles.

The TA-Luft regulation (regulation of air pollution control) is valid today in the version of 2002. This regulation takes care about the air pollution coming from technical objects like power plants, smelting plants or concrete plants. Section 5.2 of this regulation prescribes the reduction of fine dust emissions due to the production process of the particular plant. One effective measure in this sense is the integration of the production processes in capsuled areas like halls. If employees have to work in these areas or diesel driven equipment is used the implication to the usage of diesel particulate filters is given.
