(MMO) are again able to facilitate the commissioning of toxicity testing assessments in support of applications for oil spill treatment product approval under the UK national scheme. The refurbishment and reconfiguration of the Cefas laboratory facilities in Lowestoft, are now complete. To ensure compliance with the Governments COVID-19 guidance, toxicity testing in support of new product applications may take longer than usual

ToAdministration reportof the UK scheme, including approval renewals for existing products, and maintenance of the UK approved list of products will continue as normal during this time.

    Standing approvals

    A standing approval is an agreement between MMO andbetween MMO and a port or harbour authority, allowingthat approvedspecific OSTPsoil tospill treatment products may be used under certain conditions and in specific areas, without seekingapproval. further authorisation from MMO. This enablesmeans a faster response to oil spills. Standing approvals may also be given to operators of oil and gas installations in coastal waters, or fixed locations such as terminals. All decisions relating to granting standing approvals will be based on scientific advice provided by Cefas. The relevant SNCBs will also be consulted to ensure it is an appropriate response within the specified port or harbour taking in to account environmental factors.

    Port or harbour authorities,authorities and oil and gas installations must report to MMO thatto MMO that they have used a standing approval at the earliest possible opportunity.

    Standing approvals for England exist at the locations below. You can view the extent of each standing approval on the the Coastal and Marine Resource Atlas interactive interactive map, by selecting the standing approvals layer on the list of layers.
