WASHINGTON (AP) — Chief Justice John Roberts has rejected a Supreme Court appeal by the St. Louis-based natural gas company Spire Inc. to allow it to keep operating a pipeline through Illinois and Missouri.

Roberts did not comment Friday in refusing to temporarily pause a lower court order affecting the operation of the Spire STL Pipeline. The company could be forced to stop operating the pipeline on Dec. 13 unless the Federal Energy Regulatory Commission extends an emergency order granted in September.

Spire's court filing said shutting down the pipeline "in the middle of winter could result in the loss of natural-gas service to hundreds of thousands of homes and businesses" in the St. Louis region.

The environmental group opposing Spire has said the company's concerns are overblown because FERC is likely to allow the pipeline to continue to operate through the winter.

The pipeline runs for 65 miles (105 kilometers), from Scott County, Illinois, to near St. Louis, where it connects with a national network. FERC granted approval in 2018.

Spire has called it vital for providing "reliable and critical energy access to 650,000 homes and businesses throughout the St. Louis region." But the Environmental Defense Fund contended in a lawsuit that the pipeline harms land in its path, and that taxpayers will foot the bill for decades to come.

In June, a three-judge panel of the U.S. Court of Appeals for the District of Columbia Circuit ruled that FERC "failed to adequately balance public benefits and adverse impacts" in approving the pipeline. The panel also wrote that evidence showed the pipeline "is not being built to serve increasing load demand and that there is no indication the new pipeline will lead to cost savings."

The ruling vacated approval of the pipeline, prompting FERC's 90-day order allowing its continued operation.
