Spire to Expand Natural Gas Pipeline Footprint in Missouri

Determining whether to approve plans for interstate natural gas pipeline projects has never been an easy task for the Federal Energy Regulatory Commission. There are so many things to consider, chief among them the need for the pipeline, impacts on the environment and landowners along the route, and what it all means for gas customers. But as complicated as the decision-making process may be, at least pipeline developers, gas producers, and customers knew that once a new pipeline was approved by FERC, permitted, built, and put into service that the matter was closed — that is, the pipeline was here to stay. Now, in the wake of a groundbreaking court ruling on a new gas pipeline near St. Louis, things are not so certain. As it turns out, we’re intimately familiar with the matter, having just made the case that the 65-mile Spire STL Pipeline is an important addition to the regional pipeline network that provides supply diversity, improved reliability, and access to lower-cost gas. In today’s RBN blog, we consider the evolution of FERC regulation of gas pipelines and the new uncertainty that all affected parties face.

On December 15, the Federal Energy Regulatory Commission (FERC) issued a permanent certificate authorizing the Spire STL natural gas pipeline serving the St. Louis area to continue operations. Spire STL had been on a treacherous legal roller-coaster, wherein its owner got a FERC certificate in 2018, built and started operation of the 65-mile pipeline in 2019, then in 2021 saw its certificate “vacated” — wiped out — by a U.S. Court of Appeals. Then, during the white-knuckled tail end of the ride, with the winter of 2021-22 looming, Spire STL got emergency/temporary authorization from FERC to keep operating while a brand-new application for a certificate was being considered. In today's RBN blog, we discuss the case — in which RBN played a part — and what it means for upcoming midstream projects.

This summer, like the spring, winter and fall that preceded it, has seen a lot of dealmaking among midstreamers. And not just M&A and divestitures by the folks who gather, transport and process hydrocarbons but a major acquisition — and a rare IPO! — in the produced water slice of the midstream pie. Apples and oranges, maybe, but there are two common themes, namely that bigger is better and that zeroing in on core areas is key. In today’s RBN blog, we discuss some of the most significant midstream deals of Q3 2025.
