Ecuador's state-run oil company plans to spend $70 million cleaning up polluted sites in the Amazon jungle, a move that may include areas that a company owned by Chevron Corp. is accused of polluting. Petroecuador plans "to clean up the environmental pollution from all the petroleum areas currently operated by Petroecuador, which may include areas polluted by private companies, including among them Chevron," Petroecuador's general manager Marco Calvopina told Dow Jones Newswires. "Calvopina said Petroecuador's decision doesn't mean the company accepts any responsibility for the pollution. Instead, the move is in response to the government's plan to improve living conditions in the area, he said. [also refers to Texaco (part of Chevron)]
