An oil leak at the Tufts Cove power plant in Dartmouth, N.S., that spilled thousands of litres into Halifax harbour was much bigger than previously disclosed.
Nova Scotia Power has said the leak on Aug. 2 spilled about 5,000 litres into the harbour. But on Tuesday, the company said an additional 9,900 litres leaked into a containment trench and another 9,400 litres entered the cooling water system of one of its generators. #nspoli
