January 2000 spillGuanabara Bay
On January 18, 2000, a pipeline connecting one of our terminals to a refinery in Guanabara Bay ruptured, causing a release of approximately 341,000 gallons of fuel oil into the bay. We undertook action to control the spill in an effort to prevent the oil from threatening additional areas. We have spent approximately R$104 million in connection with the clean-up efforts and fines imposed by the federal environmental protection agency (IBAMA) in connection with this spill, and are subject to several legal proceedings that remain pending as a result of this spill.
