St. Louis-area Spire STL gas pipeline can move to construction phase

A Spire Inc. subsidiary was approved to begin work on the 400,000-Dth/d Spire STL natural gas pipeline project between the Rockies Express Pipeline LLC system and the St. Louis metropolitan area.

Federal Energy Regulatory Commission staff told Spire STL Pipeline LLC in a Nov. 5 letter that the company could begin construction in Scott, Greene and Jersey counties in Illinois and St. Charles and St. Louis counties in Missouri. The staff said the company met the commission's environmental conditions.

A split FERC approved the approximately $220 million pipeline project in an Aug. 3 certificate order. Commissioners Cheryl LaFleur and Richard Glick dissented. Among other things, the commissioners agreed with a rival pipeline company, Enable Midstream Partners' Enable Mississippi River Transmission LLC, and an environmental group that the commission majority should have asked for more evidence of public need for the project than an agreement for gas transportation service between Spire STL and its utility affiliate Spire Missouri Inc. The two challenging parties have since asked FERC to reconsider its certificate order.

The project will consist of about 65 miles of greenfield interstate pipeline. It will run from an interconnection with the Rockies Express pipeline in Illinois to St. Louis. In St. Louis County, the project will connect with the Spire Missouri utility and the Enable system. Spire applied for the project in January 2017. (FERC docket CP17-40)
