Air Pollution Control Commission
The Clean Air Commission (KRdL) is a professional society that has existed since 1957 and was founded by the Association of German Engineers (VDI). Since 1990, it has also been an external standards committee of the German Institute for Standardization (DIN) with a focus on air quality and has been called the VDI / DIN Commission for Air Quality Control since 2016 . The seat of the Air Pollution Control Commission is the VDI building in Düsseldorf .
The VDI technical committee for dust technology was founded on February 13, 1928 with the main focus on dust removal, dust generation, hygienic dust issues, dust technology, dust fires / explosions as well as testing and measuring. As early as 1927, the Berlin district association of the VDI had founded a corresponding technical committee, which was included in the overall association in the following year. With the dissolution of the association on November 22, 1945 on the basis of the Control Council Act No. 2 of October 10, 1945, enacted by the Allied Control Council , the technical work of the association also ended when the VDI became a member of the NS-Bund Deutscher Technik . After approval by the military government, the VDI was re-established on September 12, 1946 in the British Zone and finally in September 1949 for the entire area of the Federal Republic of Germany and West Berlin . The technical committee for dust technology was newly established in 1947 and renamed the VDI specialist group for dust technology in 1955.
In Germany , as in other industrialized countries , it was not until the 1950s that people reacted more intensely to air pollution , which had deteriorated dramatically, especially in urban areas , with the reconstruction after the Second World War . In June 1955, the VDI, which at that time had already been intensively concerned with the topic of air quality for more than 20 years, made the Interparliamentary Working Group (IPA) aware that legal regulations could only be successful if there was a well-founded set of technical rules beforehand Foundations would be created.
The German Bundestag dealt with the issue of air pollution control for the first time on the basis of a motion by the SPD parliamentary group on July 4, 1956 with the title "Air pollution by industrial companies". In the plenary session of the German Bundestag on January 11, 1957, an application was made to set up an independent commission to work out a defense plan against air pollution. The resolution of the German Bundestag of January 11, 1957 also includes a response from the Federal Government, including a proposal to set up modern technical rules in the personal responsibility of those involved.
At the beginning of 1957, the IPA then recommended the transformation of the interdisciplinary committee, founded on November 7, 1955, of the VDI dust technology specialist group into an independent and autonomously working committee for air pollution control. Since the federal government had not yet dealt with the problems of environmental protection in more detail at this point in time , it was urgently dependent on the preparatory work of expert committees and agreed to the establishment of the Air Quality Commission.
On March 15, 1957, the advisory board of the VDI dust technology specialist group decided to raise the air pollution control committee belonging to it into an independent commission ( spin-off ), which met on May 2nd of the same year for its constituent meeting and acted as the air pollution control commission Luft was founded with the task of developing technical rules that should serve the legislature as a basis for legal regulations. The tasks of the Clean Air Committee of the VDI dust technology specialist group were transferred to the newly established Air Cleanliness Commission. The first VDI guideline issued by the KRdL with the title "VDI 2091 dust ejection from steam generators over 10 t / h output" appeared in January 1958. By 1960, 15 VDI guidelines, including a catalog of sources for air pollution ( VDI 2090) and a collection of definitions (VDI 2104). The focus of the content-related work at that time, however, was on the creation of VDI guidelines on the subject of dust and gas ejection from various industrial areas (VDI 2091 to VDI 2103). The VDI manual for keeping the air clean summarized the VDI guidelines. This manual was merged with the dust manual and then reorganized. The VDI manual dust technology was no longer continued in line with technical developments. The publication of draft guidelines by the Air Pollution Control Commission has been announced in the Federal Gazette since 1964 in order to offer all interested parties an opportunity to comment.
The merger of the Air Cleanliness Commission with the DIN Air Quality Standards Committee (NLuft) in March 1990 to form the Air Cleanliness Commission (KRdL) in the VDI and DIN ended the parallel work that had been going on until then and led to the necessary harmonization of the domestic regulations with the Aim of a strategically stronger participation of Germany in the European ( CEN ) and international ( ISO ) standardization work secured by the uniform national consensus . The manual was given the new title VDI / DIN-Handbuch clean air and was expanded to include the topic of meteorology.
The mandate of the Air Quality Commission is:
“The Air Pollution Control Commission in the VDI and DIN supports the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety in carrying out its tasks in the field of air pollution control within the meaning of Section 1 of the Federal Immission Control Act. The commission determines the state of science and technology in voluntary self-responsibility and together with all parties involved (authorities, science and industry) and implements them in guidelines and technical standards. These flow into the legislation and the activities of the executive and are introduced into European and international standardization work as DIN draft standards. "
To fulfill this mandate, the work of the Air Pollution Control Commission has received state funding since it was founded. The funding amount is currently 1,423,000 € per year. The advantages and disadvantages as well as regulatory difficulties of this solution are discussed in detail elsewhere.
The Air Quality Commission is subdivided into the four specialist areas of environmental protection technology, environmental meteorology, environmental quality and environmental measurement technology. The standards and VDI guidelines developed by these departments are part of the VDI / DIN manual for keeping the air clean. Accordingly, the manual is divided into six volumes:
- Volume 1 deals with general questions, maximum permissible immission values in the air and with environmental meteorology
- Volumes 2 and 3 deal with emission reduction
- Volumes 4 and 5 deal with analysis and measurement methods
- Volume 6 deals with exhaust gas cleaning and dust technology
Environmental protection technology
The technical regulation is focused on the description of the state of the art of processes, facilities and operating modes for emission reduction and energy conversion in industry and trade, production and services as well as on the separation of solid and liquid particles , but also of gases and odorous substances.
Environmental meteorology is both fundamental and application-related, has a pronounced interdisciplinary character and comprises the disciplines of meteorology and climatology in general and the physics of the atmospheric boundary layer , atmospheric chemistry , numerical modeling , urban climatology , human biometeorology and air pollution control in particular. The technical regulation is focused on the spread and transport of gaseous and particulate emissions in the lower atmosphere. The work area begins with the transfer of substances into the atmosphere and ends with the transfer of these substances into other media.
This topic deals with the effects of air pollution on humans, animals, plants, soil, the atmosphere as well as on materials and cultural assets . The technical regulation is focused on effect-related measurement and survey methods ( biomonitoring ), maximum immission values, environmental simulation , odor-intensive substances and bioaerosols .
Environmental measurement technology
In the area of environmental measurement technology, all relevant measurement techniques in air pollution control and requirements for sampling , analysis and evaluation as well as the establishment of definitions and criteria that describe the quality of measurement methods are dealt with. The technical regulation is focused on measurement technology for individual components or substance groups of air pollutants as well as for climate-relevant gases.
