United States Attorney Michael Mosman announced today the settlement of a criminal investigation into illegal ocean pollution by the cargo ship M/V GRUMANT. Under the settlement, the operators of the GRUMANT will plead guilty to a single felony count for violations of the Act to Prevent Pollution From Ships, a federal law that implements an international treaty forbidding oil pollution of the oceans by commercial ships. Grid Odessa, Ltd., of Odessa, Ukraine, will pay a fine of $275,000 and be placed on probation. Large commercial ships use a heavy fuel oil that must be treated on board ship to remove impurities and water before it can be burned in the ship’s engine. This process creates substantial amounts of oily waste.
