Germany has an air pollution controlregulation titled "Technical Instructions on Air Quality Control" and commonly referred to as the TA Luft. The first version of the TA Luft was established in 1964. It has subsequently been revised in 1974, 1983, 1988 and 2002. Parts of the TA Luft have been adopted by other countries as well. In 1974, 10 years after the TA Luft was first established, the German government enacted the "Federal Pollution Control Act". It also has subsequently been amended a number of times, the last of which was in 2002. Although the first version of the TA Luft existed 10 years before the enactment of the "Federal Pollution Control Act", it is often called the "First General Administrative Regulation" pertaining to the "Federal Pollution Control Act". The German government created the Federal Ministry for Environment, Nature Conservation and Nuclear Safety in June, 1986 and it is now responsible for implementing the TA Luft regulation under the "Federal Air Pollution Control Act".
Overview
The TA Luft is a comprehensive air pollution control regulation that includes:
A discussion of the scope of the TA Luft application, which is to review applications for licenses to construct and operate new industrial facilities and to determine whether the proposed new or altered facilities will comply with the requirements of the TA Luft and the requirements of other air pollutant emission regulations promulgated under the Federal Pollution Control Act.
Annex 3 is devoted to guidelines on: how the atmospheric dispersion modeling required during the TA Luft review is to be performed, and the acceptable type of dispersion model to be used. In essence, the modeling must be in accordance with the VDI Guidelines 3782 Parts 1 and 2, 3783 Part 8, 3784 Part 2, and 3945 Part 3.
is an atmospheric dispersion model for simulating the dispersion of air pollutants in the ambient atmosphere. It was developed by Ingenieurbüro Janicke in Dunum, Germany under contract to the Federal Ministry for Environment, Nature Conservation and Nuclear Safety. Although not named in the TA Luft, it is the reference dispersion model accepted as being in compliance with the requirements of Annex 3 of the TA Luft and the pertinent VDI Guidelines. It simulates the dispersion of air pollutants by utilizing a random walk process and it has capabilities for building effects, complex terrain, pollutant plume depletion by wet or dry deposition, and first order chemical reactions. It is available for download on the Internet free of cost. Austal2000G is a similar model for simulating the dispersion of odours and it was also developed by Ingenieurbüro Janicke. The development of Austal 2000G was financed by three German states: Niedersachsen, Nordrhein-Westfalen and Baden-Württemberg.
