Thousands of gallons of oil have been recovered from the pipeline leak in Colerain Township, and repair efforts can start because the break in the pipe has been found.
Crews continued their efforts to clean up the mess and minimize the environmental effects Thursday.
The work reached a milestone Monday night, as crews discovered the site of the leak. A 5-inch crack on the underside of the pipe caused approximately 10,000 gallons of oil to leak.
Officials said they cannot tell how long the leak had been going on, but residents said that they had been smelling oil since late February.
With the exact break site located, crews are working to make repairs, but that could take some time.
