On August 8, 2025, the Federal Energy Regulatory Commission (FERC) issued an enforcement order in Skye MS, LLC (Skye) and levied a $45,000 civil penalty on an intrastate pipeline operator in Mississippi, resolving an investigation into the operator’s violations of section 311 (Section 311) of the Natural Gas Policy Act (NGPA). FERC faulted the operator for providing a Section 311 transportation service without timely filing a Statement of Operating Conditions (SOC) and obtaining FERC’s approval for the transportation rates. Section 311 permits intrastate pipelines to transport interstate gas “on behalf of” interstate pipelines without becoming subject to FERC’s more extensive Natural Gas Act (NGA) jurisdiction, but requires the intrastate pipeline to have an SOC stating the rates and terms and conditions of service on file with FERC within 30 days of providing the interstate service. Under the NGPA, Section 311 rates must be “fair and equitable” and approved by FERC. In Skye, FERC stated that the operator began providing Section 311 service on certain pipeline segments in Mississippi in May 2023, following their acquisition from another Section 311 operator, but did not file an SOC with FERC until April 2025. The order ties the penalty to the approximately two-year delay between commencement of the Section 311 service and the SOC filing date. The pipeline operator was also ordered to provide an annual compliance report and to abide by additional verification requirements related to the filing of its FERC Form No. 549D, the Quarterly Transportation & Storage Report for Intrastate Natural Gas and Hinshaw Pipelines.
