Description

BOEMRE has entered into an Interagency Agreement with the U.S. Environmental Protection Agency (EPA) to conduct laboratory dispersant effectiveness tests (DE) using the Baffled Flask Test (BFT) on twenty crude and fuel oils using the dispersant Corexit 9500.

BOEMRE funded and conducted a research project at Ohmsett - The National Oil Spill Response Research and Renewable Energy Test Facility located in Leonardo, NJ to provide large-scale test tank DE data on twenty crude and fuel oils using Corexit 9500 dispersant. Laboratory-scale DE tests will be conducted using the same dispersant and oil combinations, and results will be compared to determine if the bench-scale test results can be used to provide reasonable estimates of field performance.

BOEMRE has sent the required samples of crude and fuel oils as well as the dispersant (Corexit 9500) to the EPA. The EPA will conduct the BFT tests on twenty crude and fuel oils using Corexit 9500 dispersant at a fixed temperature of 15 ℃. At the conclusion of the testing, EPA will prepare a report that presents the results of the BFT tests.

Latest progress update

Twenty samples of crude and fuel oils were sent from the Ohmsett facility to the U.S. Environmental Protection Agency for Baffled Flask Test (BFT) dispersant effectiveness testing using the dispersant Corexit 9500. Analyses of the oil are complete. EPA has prepared the final data report and is undergoing internal QA/QC evaluation. BOEMRE has reviewed and accepted the final report for the project.
