Brazil has fined U.S. oil giant Chevron US$5.4 million for breaching its environmental license when it tackled an oil spill in November, the BBC reported.

Brazil's Ibama environmental agency said Chevron lacked the necessary equipment and was slow to respond.

Ibama had already fined Chevron US$28 million for causing the spill off the coast of Rio de Janeiro.

Chevron is also facing an US$11 billion lawsuit over the spill of crude oil at the Frade Field.
