IPPC treatment plants – Control and updating of the authorisation

General information

The permit for an IPPC Treatment Plant must be regularly controlled and updated. The owner of the plant shall make regularly the necessary adaptations  to the state-of-the-art. These adaptions have to be taken within a period of four years after the publication of the BAT conclusions (= conclusions on the best available technologies, which are published in the Official Journal of the EU) on the main activity of an IPPC plant.

Please note

The BAT conclusions are available on edm.gv.at.

The permit must, within a period of 4 years after the publication of BAT conclusions on the main activities of an IPPC plant, check and update the permit. Moreover, the authority orders, if required, measures by decree, if

  • the environmental pollution caused by the IPPC plant is so significant that the emission threshold values laid down in the authorisation have to be reviewed or revised,
  • operating safety requires the use of other technologies,
  • a legal provision which is to be applied (among others) in the authorisation procedure, which is new or has been amended, requires adaptation,
  • no BAT conclusions apply to the IPPC plant; however, developments of the state-of-the-art render a considerable reduction of emissions possible.


The owner of the plant shall review herself/himself regularly the permit.

In any case the owner of the plant must, within a period of one year after the publication of the BAT conclusions on the main activity of an IPPC plant, inform the authority whether for the adaptation to the state-of-the-art or to these BAT conclusions a change or an updating of the authorisation which is subject to approval or notification, is required.

Furthermore the owner must regularly make the necessary adaptations to the state-of–the-art. The owner must do this at least within a period of four years after the publication of the BAT conclusions on the main activity of an IPPC plant.


If the owner of the treatment plant has, after the expiry of the deadlines, after repeated reminder indicating the legal consequences, failed to carry out adaptations to the state-of-the-art, the competent authority shall mandate the closure of the plant or the parts of it causing environmental pollution.

Competent authority

The waste management authority which is locally in charge of the site:


Changes concerning the adaptation to the state-of-the art can be changes subject to authorisation, which have to be authorised by the competent authority in advance. In this case an authorisation procedure will be carried out.If no change subject to authorisation (e.g. decisive change) for the adaptation to the state-of the-art is required, the competent authority must, as a rule, only be notified thereof. Please ask the competent body in advance.

Required documents

Application for authorisation and documents to be enclosed can be found in the chapter "IPPC Treatment Plants – Approval Procedures".

Costs and fees

Costs depend on various ordinances on levies and fees. It is recommendable to gather more detailed information from the competent authority beforehand.
