A Texas company reported that its 1,230-mile Appalachia to Texas Pipeline will begin service in December.
Enterprise Products Partners said the ATEX pipeline will carry ethane from the Utica and Marcellus shales to Texas.
The $1.2 billion pipeline was originally slated to begins ervice in early 2014.
It is designed to carry 190,000 barrels per day initially and to carrry 260,000 barrels per day later.
The company also has plans to move propane via the same pipeline, beginning in early 2015.
The news came from a Pittsburgh conference earlier this week.
The line runs 264.61 miles across 13 Ohio counties, entering the state on the east side at Jefferson County, passing through Harrison, Tuscarawas, Coshocton, Muskingum, Licking, Fairfield, Pickaway, Fayette, Greene, Clinton, Warren and exiting at Butler County north of Cincinnati.
In all, the 369-mile, 20-inch diameter pipeline would extend from southwest Pennsylvania's Washington County to Seymour, Ind., where it would connect with an existing Enterprise pipeline that runs 861 miles through Illinois, Missouri, Arkansas, Louisiana and Texas.
The existing 16-inch pipeline, which brings refined product from the Gulf Coast to Indiana, would be reversed to accommodate the new product.
At the Texas end, an additional 55 miles of new pipeline would extend from Beaumont to a natural gas liquid storage complex at Mont Belvieu.
