Keystone Pipeline leak thousands of gallons worse than first reported
But we need more pipelines, right?
Nearly a week after pipeline operator TransCanada shut down a section of its Keystone line over an oil leak, the company reported Thursday thousands of gallons of oil were spilled, not less than 200 as it first said.
Based on soil excavations, TransCanada said about 16,800 gallons of oil leaked onto a field in South Dakota, the Associated Press reported. After the leak was discovered Saturday and the line was shut, TransCanada said about 187 gallons of crude oil had spilled, an accident that environmental groups said shows the dangers of shipping oil by pipeline. Though the spill is larger than first thought, it poses no significant environmental effects or threats to public safety, the AP said. However, Keystone transports Canadian tar sands oil, which is more difficult to clean than conventional oil.
