titled "Technical Instructions on Air Quality Control" (''Technische Anleitung zur Reinhaltung der Luft'') 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" (''Bundes-Immissionsschutzgesetz''). 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

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 (or altered existing 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''.
