Oily drainage water and other oily water may be discharged to sea subsequent to treatment.
The oil content in water as mentioned in the first subsection and discharged to sea, shall be as low as possible, cf. Chapter II of the Framework Regulations and Sections 7 and 8 of the Management Regulations. In any event, the oil content shall not exceed 30 mg oil per litre of water as a weighted average for one calendar month.
Treatment systems shall be operated such that the environmental strain from discharges to sea will be as low as possible
Chemicals that accompany water as mentioned in the first subsection to sea after cleaning, must be covered by a discharge permit, cf. Section 66, first subsection. Adding chemical residue or other waste to oily water that is discharged to sea pursuant to this section, is not allowed.
Oily drainage water and other oily water that are not handled in accordance with the first to fourth subsections or injected in accordance with the permit, cf. Section 71, shall be collected and sent as waste to a legal waste facility. It is not allowed to add drainage water and other oily water to the production stream ashore.
The operator shall carry out comprehensive assessments to ensure that the best environmental solution for handling drainage water and other oily water is selected.
The Norwegian Environment Agency can set additional requirements regarding discharges of drainage water and other oily water.

The operator must obtain a permit from the Norwegian Environmental Agency for petroleum activities under Chapter 3 of the Pollution Control Act (in Norwegian only). Application for permit under the Pollution Control Act is subject to Chapter 36 of the Pollution Control Regulations (in Norwegian only), and a fee is fixed for the Environmental Agency’s processing relating to applications for permits pursuant to Chapter 39 of the Pollution Control Regulations (in Norwegian only). The regulations’ general requirements for the petroleum activities on the continental shelf apply to all operators.
The permits under the Pollution Control Act will normally contain conditions that are specific and adapted to each activity. Chapter 36 of the Pollution Control Regulations (in Norwegian only) gives further provisions on the processing of permits under the Pollution Control Act. The Norwegian Environment Agency has described further expectations for the content of applications and expected processing time in the Guidelines for applications regarding offshore petroleum activities: https://lovdata.no/dokument/NL/lov/1981-03-13-6?q=forurensingsloven#KAPITTEL_3. Chapter 39 of the Pollution Control Regulations (in Norwegian only) gives provisions for fees for work with permits.
