Reference excerpt

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. 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 Nuclear Safety (Bundesministerium für Umwelt, Naturschutz und Reaktorsicherheit) 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 (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. Air pollutant emission limits for dust, sulfur dioxide, nitrogen oxides, hydrofluoric acid and other gaseous inorganic fluorine compounds, arsenic and inorganic arsenic compounds, lead and inorganic lead compounds, cadmium and inorganic cadmium compounds, nickel and inorganic nickel compounds, mercury and inorganic mercury compounds, thallium and inorganic thallium compounds, ammonia from farming and livestock breeding operations, inorganic gases and particulates, organic substances and others. Emission limits may also be set for hazardous, toxic, carcinogenic or mutagenic substances as part of the TA Luft review procedures. Other limits or requirements related to stack heights (for flue gases or other process vents) and for storing, loading or working with liquid or solid substances. Various requirements for sampling measuring and monitoring emissions. Listing of the industries subject to the requirements of the TA Luft, such as mining, electric power generation, glass and ceramics, steel, aluminum and other metals, chemical plants, oil refining, plastics, food, and others. 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. The full text of the TA Luft is available on the Internet.

AUSTAL2000 AUSTAL2000 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 (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. 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.

Worked examples

Example 1 — a first encounter with TA Luft

Start with the simplest possible case. Write down what TA Luft claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to TA Luft before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about TA Luft ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of TA Luft

In research: TA Luft appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses TA Luft in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: TA Luft is common in secondary-school and first-year university syllabi. It links to neighbouring topics Air pollution, Atmospheric dispersion modeling, Environmentalism in Germany, so understanding it makes those chapters shorter.
In everyday life: Look for TA Luft outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is TA Luft in simple terms?

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. The first version of the TA Luft was established in 1964.

Why does TA Luft matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study TA Luft?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
