The amendment to the Air Protection Act introduces a minimum distance requirement for selected stationary sources that may significantly affect the surroundings through dust or odour. The new rules are important especially when siting new sources, when making changes in spatial planning, and when preparing expert reports and operating rules.

The unified environmental opinion, abbreviated JES, consolidates multiple environmental statements, binding opinions, and decisions into a single basis for permitting a project. For projects subject to EIA, it is important to decide correctly whether JES should be addressed together with the EIA process, or only subsequently after the EIA opinion is issued.

A noise study and noise measurement are not the same thing. A noise study usually assesses in advance by calculation what noise a project, technology, facility, transport, heat pump, or HVAC unit will produce after implementation.

Complaints about noise from an industrial facility should be addressed substantively and in good time. First, it is necessary to establish where the noise actually comes from, what operating regime the facility runs under, and whether the problem may occur during the day or at night.

An expert opinion under the Air Protection Act is an important document when permitting new stationary sources, changing operation, and communicating with the regional authority. It is typically addressed for sources listed in Annex No.

A dispersion study assesses how emissions from a stationary source, traffic, or other project will manifest in surrounding air quality. In practice it is addressed especially when permitting new sources, operational changes, capacity increases, significant related traffic, or in proceedings where the regional authority needs to assess immission contributions of the project.

The amendment to the Air Protection Act carried out by Act No. 42/2025 Coll.

Operators of boiler plants, paint shops, technological lines, and other stationary sources often face the question of whether they must commission authorised emission measurement, or whether another expert supporting document is sufficient for the given situation. What matters most is the type of source, operating permit conditions, technology change, and the purpose for which the output is to be documented.
