The Bureau of Safety and Environmental Enforcement (BSEE) is conducting comparative dispersant testing in warm water at the Ohmsett Facility test basin.  This work builds off of the cold water test conducted in 2014 (Project OSRR 1016). Five dispersants were selected from the Environmental Protection Agency's (EPA) National Contingency Plan (NCP) Product Schedule and were tested on a Gulf of Mexico crude at Ohmsett. They include Corexit® EC9500A, Finasol® OSR 52, Accell® Clean DWD, Marine D-Blue Clean, and ZI 400.
