Within the scope of the environmental impact analysis stipulated by the law, aspects of how the Zwentendorf/Dürnrohr incinerator could impact on the environment were studied. The process was based on an environmental impact statement drawn up by the future operator.

As a result of the analysis, the responsible government authorities set up stringent criteria which EVN Abfallverwertung NÖ has undertaken to observe. These criteria affect all areas of environmental protection, from clean air to noise abatement, traffic, agriculture, forestry, hunting, fishing, etc.

Issuance of the licence under the nature conservation act was similarly dependent on extremely strict criteria which even stipulate employing a separate ecological construction site supervisor.
