Kinder Morgan, the Texas-based energy company that wants to run a 360-mile petroleum pipeline through Upstate South Carolina and Coastal Georgia, is dealing with a leak of more than 250,000 gallons from one of its existing pipelines in South Carolina, officials said. That leak is in the Plantation Pipeline in Belton, South Carolina, which is where the proposed Palmetto Pipeline would tie in and extend down along the Savannah River and the Georgia coast on its way to Jacksonville, Florida. According to maps Kinder Morgan released during a recent public hearing in Richmond Hill, 11 miles of the pipeline would be in Bryan County.
