Spire STL Pipeline is a natural gas pipeline.


The pipeline runs through Scott, Greene and Jersey counties in Illinois, and St. Charles and St. Louis counties in Missouri.[1][2]

Project Details

  • Parent Company: Spire STL Pipeline LLC[3]
  • Proposed capacity: 400 Million cubic feet per day[3]
  • Length: 65 miles / 104.6 km[3]
  • Status: Operating[3]
  • Start Year: 2019[3]


The Spire STL Pipeline is owned and operated by Spire STL Pipeline LLC.[4] The pipeline would interconnect with the existing Rockies Express Pipeline in Scott County, Illinois.[1]

In July of 2016, Spire Energy applied to FERC to build the pipeline.[5] In August of 2018, the Federal Energy Regulatory Commission (FERC) approved an order issuing a Certificate of Public Convenience and Necessity for the Spire STL Pipeline, with this approval, the pipeline can move forward with land acquisition and other pre-construction activities.[6]

In February of 2019, land was being cleared for construction which was expected to be complete by July 2019.[7]

In August of 2019, Spire STL Pipeline filed an amended application with FERC requesting approval of revised recourse rates due to an increase in estimated construction costs. Spire says historic flooding of major rivers along the pipeline route has caused construction delays, which it warned will cause construction costs to exceed $240M, the top end of the range of estimated costs, and that the expected in-service date would shift to later in 2019.[8]

The pipeline was put into service in the first quarter of 2020.[9]

Environmental Impact

FERC issued its Environmental Assessment of the pipeline in September 2017.[10] The EA assesses the pipeline's impact on greenhouse gas emissions (GHG). "The Project would deliver up to 400,000 Dth/d of natural gas volumes, which can produce 7.7 million metric tons of CO2 per year from end-use combustion (USEPA 2017d). However, as described in Section A.2 (Purpose and Need), this Project was not developed to serve new demand. Thus, the majority of the natural gas provided by the Spire STL Pipeline Project would be replacing, not adding to, other fuel sources that are currently contributing GHGs to the atmosphere. Therefore, we do not anticipate that the end-use would represent new GHG emissions."[10]
