Biocide Use in Dutch Regulated sector of North Sea (update 6 May 2010)

Cefas, on behalf of the State Supervision of Mines (SSM) in the Netherlands, is currently carrying out enquiries to identify if substances deliberately added to offshore chemicals are biocidal in their primary function or can act as biocides in a secondary function. The deadline to complete the biocide form sent in an Email dated the 12th of April 2010 was set to be 12th of May 2010. These enquiries were recently discussed with the Netherlands competent authories by representatives of the oil and gas operators (NOGEPA) and offshore chemical suppliers (EOSCA) in the Netherlands, who requested an extension to this deadline.

The NL competent authorities agreed with the industry to extend the deadline to 15th of June 2010 and also to resend the amended list of products registered at Cefas which may contain substances with potential biocidal action. In the amended list, these substances are mentioned by name and CAS number (except where the identity of the identified substance is supplied by a third party supplier through a Letter of Access, in which case the name and CAS number are not mentioned but indicated with the abbreviation LoA. In this case the supplier will need to ask the third party supplier to submit the information to Cefas).

Background to the way Cefas generated the lists of products containing substances with a potential biocidal action

In 2009 Cefas conducted some work to abstract the Netherlands Black, Purple, Red, Orange, Yellow and undetermined lists from the document Prioritering risicovolle biociden published (in Dutch only) by the Netherlands Ministry of Housing, Spatial Planning and the Environment. These lists, along with Annex I and Annex II from EC No 1451/2007 on Biocides, were searched against the Cefas database utilising CAS number matching. The lists generated in 2009 were used to produce lists of products by supplier that contain substances with a potential biocidal action. Due to issues of confidentiality concerning Letters of Access, Cefas did not include the names of the substances involved on the lists sent to suppliers in the email that was sent out on April 12th.

Which actions by SSM are foreseen in case the biocide forms are not completed by the 15th of June 2010

In case the biocide forms are not completed, whenever an operator requests for permit to use and discharge the product of concern in the Netherlands, the operator will be informed that the product may contain a substance having a potential biocidal action for which no information has been received by the supplier during this exercise. The operator will also be informed that the permit will not be issued unless the biocide forms have been completed.

During enforcement actions, suppliers must respond to the questions raised in the biocide forms otherwise administrative or criminal penalties will be imposed.
