- Fish receptions and slaughterhouses are covered by the Industrial Emissions Directive, which gives authority to set emission requirements. Approximately every six years, one looks at what new technology is available, which means that one normally sets lower limit values ​​for emissions. In December, the new values ​​come into force, says Henrik Stenwig. He is director of environment and health at Sjømat Norge. The requirements for salmon slaughterhouses and fish reception are the same, and mean that the process water must be cleaned before it is discharged. According to Stenwig, there are requirements for maximum concentrations in the water that is discharged.

- One does not assess the recipients' tolerance either, but sets requirements for maximum concentrations, says Stenwig.

In practice, this does not mean that small facilities that release relatively little water have easier cleaning requirements than large facilities.

In practice, there is also no distinction between whether the water is discharged into a narrow fjord, or into open waters, or whether you live alone or have many neighbors who also discharge process water.
