Permissons Langøya

NOAH abides by the regulatory permits for the treatment plant for inorganic hazardous waste on Langøya. It is the Environment Directorate and the Norwegian Radiation Protection Authority that are the responsible authorities for these permits.


Permits and authorisations

The permit from the Environment Directorate is dated 08.07.2014 and sets the requirements and terms for the operation in Langøya.
NOAH can receive the following annually:

  • 500,000 tonnes of inorganic hazardous waste
  • 500,000 tonnes of polluted mass

This means that NOAH can receive an annual amount of 1000,000 tonnes, calculated as an average over 5 years.

Changes in relation to former permits are increased fill height for hazardous waste and a depot for ordinary waste in Sydbruddet. Permission is granted to increase the filling heights for landfill for hazardous waste in Sydbruddet from -5 to 0. Moreover, permission has been granted to use non-hazardous waste for the construction of roads, dams and the like in the landfill for hazardous waste Sydbruddet.

NOAH has also been granted permission to dispose of alun metal in the landfill for hazardous waste on Langøya.

The amended permit includes special permission for specific emissions for PFOS, PFOA and 6:2 FTS for water.


The permit covers naturally occurring (in nature) radionuclides from petroleum and mining. The largest tonnage received is alun metal, which is dug up during construction activity primarily in the Oslo Fjord area.
