The Globe reports Boston will go to court to appeal a recent federal ruling dismissing arguments by the city, several elected officials and West Roxbury residents that the West Roxbury pipeline should be stopped.

Less than a month ago, an aide to the mayor was telling West Roxbury residents the pipeline was a done deal and that the city was confining its efforts to begging Algonquin Gas Transmission to hold a meeting to show depictions of its planned gas transfer station at Grove and Centre streets, where gas from the high-pressure pipeline would be fed into National Grid's system.

In September, a federal judge rejected city efforts to force Algonquin and its contractor, Spectra Energy, to at least delay the project over the issue of city permits for digging trenches along Washington and Grove Streets. Spectra has since installed parts of the pipeline under the streets and cleared the site of the proposed transfer station of trees.

The city appeal will be of a Jan. 28 ruling by the Federal Energy Regulatory Commission that rejected a request by city officials and US Rep. Stephen Walsh, state Rep. Ed Coppinger and state Sen. Michael Rush, several West Roxbury residents, West Roxbury Saves Energy and the Conservation Law Foundation to reconsider its 2015 approval of the pipeline.

The commission rejected their arguments that it had failed to consider that a high-pressure pipeline and transfer station could pose a public-safety risk in a densely populated area, that there wouldn't be a need for the pipeline if local utilities would fix all the leaks in their existing pipes, and that digging a trench for the pipe under Gonzalez Park in Dedham without legislative approval violates the state constitution.

In its rejection, the commission said its staff did too look at safety concerns and found the pipe and station would be safe, that the fact that Algonquin has already signed up both natural-gas producers to pump gas into the pipe and utilities willing to buy it proves there's a need and that even if the utilities fixed all their leaks, that still wouldn't equal the extra capacity the new pipeline will mean.

As for needing the approval of the state legislature, the commission snorted that federal pipeline law was written specifically to preempt local and state jurisdictions.
