Line 19, Colonial Pipeline Co.’s gasoline line between Atlanta and Nashville, TN, remained shut Monday after officials closed it Saturday after a possible spill, a company spokeswoman said.
The line initially shut down after gasoline odors ended up reported to the Chattanooga Fire Department, the pipeline said in a notice to shippers on Sunday.
Colonial officials were still looking for the source of a “very small leak” on Monday.
The leak caused gasoline to release into Shoal Creek, which in turn empties into the Tennessee River, a spokesman for the Chattanooga Fire Department said.
Colonial said it was a “very small” leak, and there was no danger to the public, he said.
Colonial has since restarted Line 20, a distillates line, which they also shut down as a precaution.
On Sunday, crews began excavating portions of Line 19 to identify the suspected leak source and assess repair options. The area is surrounded by hilly, rocky terrain, and the excavating process has been slow. Colonial’s top priority is to ensure the safety of the public and the responders, officials said.
Local, state and federal authorities, including the Environmental Protection Agency, are providing oversight and assistance within a collaborative Unified Command structure. Colonial, along with its federal, state and local government partners, continues to monitor the air and water in Shoal Creek and the Tennessee River. The Chattanooga Fire Department remains on site to provide safety support, and continues to find no risk to public safety.
Colonial Pipeline, the largest refined products system in the U.S., can carry more than 3 million barrels of gasoline, diesel and jet fuel between the U.S. Gulf Coast and the New York Harbor area.
