CHARLOTTESVILLE, Va. (WVIR) - An environmental nonprofit in Charlottesville has filed a lawsuit against the National Park Service about how it handled records related to its decisions on the Atlantic Coast Pipeline.

The Southern Environmental Law Center filed the lawsuit after it says the National Park Service has had an “unreasonable delay in responding to record requests.”

The law center says it requested the documents through the Freedom of Information Act back in December of 2017.

More than a year later, attorneys with the center say they do not have the documents and have had very little communication with the park service.

They say the records would help them understand how and why the park service decided to approve the Atlantic Coast Pipeline crossing spots like the Blue Ridge Parkway and the Appalachian Trail.

“So we filed this lawsuit trying to finally get those documents that we need, that everyone needs to understand how the decision was made, how the park service decided that it would be OK to let the pipeline cross these treasures,” Kristin Davis, an attorney with the SELC, said.

The group filed the suit in Charlottesville's federal court on Thursday, February 21.

Attorneys with the Southern Environmental Law Center believe they should be hearing from a judge in the next couple of weeks.
