In most cases, new investments and extensions to existing facilities can only be started with the consent of the Environment and Nature Protection Authority. For small projects, it is sufficient to prepare a Preliminary Assessment Document (PAD), while for larger projects an Environmental Impact Assessment (EIA) or an Integrated Pollution Prevention and Control (IPPC or EIA) permit may be required.
An environmental permit is also required to start a number of other activities (e.g. waste transport, air pollutant emissions, etc.), to excavate contaminated sites, to remediate.
