Offshore Chemical Notification Scheme
The Offshore Chemical Notification Scheme (OCNS) applies to chemicals that are intended for use and discharge in the exploration, exploitation and associated offshore processing of petroleum in the UK and Netherlands. The scheme is regulated in the UK by the Department for Business, Energy & Industrial Strategy (BEIS) using scientific and environmental advice from Cefas and Marine Scotland. In the Netherlands, the scheme is regulated by the State Supervision of Mines (SSM) with scientific and environmental advice from Cefas and the Netherlands Oil and Gas Exploration and Production Association (NOGEPA).
OCNS Bulletin Board
Protocols for the Netherlands OCNS are available by following the links below.
The OCNS uses the OSPAR Harmonised Mandatory Control Scheme (HMCS) developed through the OSPAR Decision 2000/2 on a Harmonised Mandatory Control System for the Use and Discharge of Offshore Chemicals (as amended by OSPAR Decision 2005/1) and its supporting Recommendations. This ranks chemical products according to Hazard Quotient (HQ), calculated using the Chemical Hazard and Risk Management (CHARM) model.
Within this OCNS section, further information may be found on the background and relevant details including the updated Ranked Product Listing and documents required for chemical certification.
