Environmental permits and the TUA

Portugal’s Single Environmental Permit (TUA) brings together decisions applicable to an installation. An alleged breach must be assessed against the specific regime, condition and version in force at the time.

What to check in your case

We compare changes to the industrial process with applications on SILiAmb and licensing decisions. Filing an application alone requires legal assessment before deciding whether the change could start.

Documents for your defence
