We're committed to protecting the environment and an open process that provides the opportunity for all voices to be heard.

As an interstate project, the Spire STL Pipeline will be reviewed for siting and permitting by the Federal Energy Regulatory Commission (FERC). The FERC will be the lead agency for other federal and state, and local permitting authorities. The pipeline will be wholly owned and operated by Spire STL Pipeline LLC. Information regarding our regulatory filings is available under Docket No. CP17-40 in FERC's eLibrary website here
