OilSpillTreatmentProductApprovalScheme
• MMO maintain the UK approved list of OSTP• Several kinds of products: Dispersants, Sorbents, Bioremediation,
etc...• All products must pass two toxicity tests – “Rocky shore” & “Sea”
tests• Dispersants must also pass efficacy testing• Bioremediation products must pass additional toxicity testing
Only products manufactured whilst their approval is valid can be considered for use in UK waters

Dispersant Efficacy Testing
Rotating flask test WSL LR 448
Test oils characteristics: 1. Dynamic viscosity @ 10°C: 1800-2200 mPa s 2. Dynamic viscosity @ 10°C: 450 to 550 mPa s
Oil + dispersant in seawater.2 min rotation, 1 min settle.50ml of oily water run out through bottom tap.Remaining volume of oil indicates success of dispersion

Rocky Shore Test
Dispersant vs Oil
Test organism: Patella vulgata, the Common Limpet
Test oil: Kuwait Crude
Oil/OSTP sprayed onto test plate on which limpets are mounted.
Test is passed if dispersant doesn’t cause significantly more mortality (measured by loss of adhesion) than oil.

Sea Test
Dispersant vs oil + dispersant
Test organism: Crangon crangon, the Brown Shrimp
Test oil: Kuwait Crude
Oil/oil & OSTP added to tankcontianing shrimp with, mixing energy added.
Test is passed if dispersant + oil doesn’t cause significantly more mortality than oil alone.

Corexit9500&9572(&ChemkleenOSDAJSA)
•Since 1996 all products must pass BOTH toxicity tests
•Corexit 9500 & 9572 & Chemkleen OSDA JSA were removed from the approved list in 1998.
•Stocks predating the 1998 removal may still be used under certain conditions

2011 Approval Scheme Review
• Regular “fit for purpose” review
• Given switch to MMO, and globally significant incident, is UK scheme still relevant?
• Issues: Dispersants to treat heavy fuel oils, phototoxicity, status of old stocks, fee structure, European harmonisation, etc..
