Section last changed: 01 January 2020
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 36 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://www.miljodirektoratet.no/ansvarsomrader/forurensning/petroleum/for-naringsliv/soknadsveileder-petroleum/. Chapter 39 of the Pollution Control Regulations (in Norwegian only) gives provisions for fees for work with permits.
By well control events is meant failure of one or more well barriers where the failure results in unintentional flow of formation fluid into the well, cross flow into the well or outflow to the external environment, see the guidelines to Section 86.
The chemicals shall be tested, evaluated and selected as mentioned in Sections 62, 64 and 65.
The overview is not required to be sent to the Norwegian Environment Agency, but it shall be available on request.
