As a result of the immission measurement, sampling and analysis, an immission report is prepared in accordance with the report format specified in the Regulation on the Control of Industrial Air Pollution. As stated in Annex-2 of the Regulation on Control of Industrial Air Pollution; Measurement, Calculation and Measurement Time of Air Quality in the Facility Influence Area:

​

• In existing facilities; Within the scope of the internationally accepted and widely used distribution models, methods and principles in Annex-2, in the facility impact area, a station in each study area in different study areas where the air pollution contribution values (HKKK) calculated for the peaks of the study areas are the highest. Air quality measurements are made continuously for one month by establishing at least two stations. In regions where the pollution changes and increases depending on the months, the competent authority determines the measurement time.

• In the new facilities to be established, there is a contribution value to air pollution within the framework of the principles in Annex-2 in the facility impact area. In addition, the long-term value (UVD) is found by calculation or measurement, taking into account all the important pollutants present in the plant impact area. For new facilities to be established; Total pollution value (TKD) is calculated from the sum of the air pollution contribution value (HKD) calculated within the facility's impact area and the long-term value (UVD) found by measurement or calculation. Competent authority; Depending on the pollutant source density in the area of influence of the facility to be established, air quality measurements can be made at a station for 1 (one) month, if necessary.

• If Passive Sampling Method is used in air quality measurements; At least 4 passive sampling points are selected for a period of 2 (two) months in the study area with the highest Contribution to Air Quality calculated according to the modeling results. In other study areas where air pollution is intense, 2 passive sampling points are selected for each study area, provided that there are at least two study areas. In the study areas where air pollution is intense, the number and place of passive sampling are determined depending on the capacity of the enterprise and the pollutant emission load (taking into account the height of the chimneys in the enterprise, mass flow rates, distribution directions of the pollutants and the residential areas in the region). The sampling location, number and/or duration may be increased by the competent authority.

• During the precipitated dust measurement; at least 2 (two) measurement points within the facility inspection area, taking into account the prevailing wind direction. If there are other sources of dust emission in the same area, the number of measurement points can be increased to determine the contributions of other sources outside the facility. The measurement period is 2 (two) one-month measurements and a total of 2 (two) months. The values to be found on a monthly basis are divided by the number of days and the average amount of dust settled in a day is calculated.

• As a rule, air quality measurements are made at heights between 1.5 and 4.0 meters above ground level, keeping a side distance of at least 1.5 meters from the building (or cultivated area). Measurements made in the forest should be made higher than the tree height.

• The acceptability of the Measurement Methods is registered after they are standardized by TSE and notified by the Ministry. If the relevant TSE Standard is not available, method standards in accordance with DIN and EPA norms, whose reliability is accepted by the Ministry, are applied. The methods are announced with the communiqué.

• Air quality and emission measurements in the facility's impact area are made by private or public institutions/organizations that have laboratories that are accredited or approved by the Ministry.
