Germany has an air pollution control regulation titled "Technical Instructions on Air Quality Control" (Technische Anleitung zur Reinhaltung der Luft) and commonly referred to as the TA Luft.
In 1974, 10 years after the TA Luft was first established, the German government enacted the "Federal Pollution Control Act" (Bundes-Immissionsschutzgesetz).
The German government created the Federal Ministry for Environment, Nature Conservation and Nuclear Safety (Bundesministerium für Umwelt, Naturschutz und Reaktorsicherheit) in June, 1986[4] and it is now responsible for implementing the TA Luft regulation under the "Federal Air Pollution Control Act".
It was developed by Ingenieurbüro Janicke[6] in Dunum, Germany under contract to the Federal Ministry for Environment, Nature Conservation and Nuclear Safety.
It simulates the dispersion of air pollutants by utilizing a random walk process (Lagrangian simulation model) and it has capabilities for building effects, complex terrain, pollutant plume depletion by wet or dry deposition, and first order chemical reactions.
