A medium combustion plant is any technical device with a rated thermal input of 1 MW or more and less than 50 MW in which combustible products are oxidised in order to use the heat thus produced, such as combustion plants, engines and gas turbines. All medium combustion installations must be registered with the Environmental Administration, which keeps a public register with information on each installation. The operating conditions and the obligations of the operators of these installations are laid down in the Grand-Ducal Regulation of 24 April 2018 on the limitation of emissions from medium combustion installations.

Luxembourg's surface water bodies have been grouped into so-called "study zones", which essentially correspond to the country's major catchment areas. Seven study zones have been designated in total.

The flood risk management directive (directive 2007/60/CE) consider the development of flood risk management plans as an appropriate tool to prevent or reduce the adverse effects of flood events. The focus is particularly on prevention, protection and precautions. The catalog of measures drawn up for Luxembourg corresponds in its structure and basic statements to the German LAWA catalog of measures.

The relatively quiet urban oases include public green areas and open spaces with a high quality of living space and an appropriate design as compensation areas within walking distance of residential and work locations. Due to their inner-city location, they do not, or do not completely, meet the above-mentioned criteria of a quiet area, e. g. by showing an increased noise level or being significantly lower. However, the urban planning context of the areas has noise-reducing properties, which lead to the fact that the urban oases in their core areas are considerably calmer than their surroundings. These areas make it possible, for example, to take short walks for those seeking peace and quietness in the immediate vicinity of their homes or workplaces.

The quiet areas in rural areas include large, cohesive and intact open spaces of supraregional importance with a high recreational function and corresponding development for leisure and recreation. These spacious areas allow for example extensive walks without crossing noisy areas.

The quiet urban landscape areas include relatively large, continuous open spaces of at least regional importance with a high recreational function and corresponding development for leisure and recreation. Its importance lies in the balancing function to the noisy and densely populated areas of the agglomeration of Luxembourg. The quiet urban landscape close to the residential area allows, for example, extensive walks with only occasional crossing of areas with higher noise levels.

The hydromorphological status was determined by a monitoring compliant with the Water Framework Directive (Directive 2000/60/EU). The elaboration of a structural quality mapping is one part of this monitoring. Within the scope of the work on the structural quality mapping, a total of 31 parameters in the area of the river bed, the river bank and the floodplain are assessed so that the structural quality mapping contains detailed information on the river morphology and the river continuity. In this case, the evaluation of the mapped sections is based on five classes. The areas river bed, left river bank, right riverbank, left floodplain and right floodplain are represented in 5 strips.

The chemical status of the surface water bodies is assessed as being good or failing to achieve good chemical status. The assessment of the chemical status for the second river basin management plan is based on the list of substances of directive 2008/105/EC and the environmental quality standards established by the new directive 2013/39/EC. The assessment without the ubiquist substances permita to get a differentiated picture of the actual situation.
