The Latest on the legal fight over the Dakota Access pipeline (all times local):
The Army Corps of Engineers says it won't yet authorize construction of the four-state Dakota Access pipeline on federal land in southern North Dakota.
The corps also is asking Energy Transfer Partners to respect the government's earlier request that it voluntarily stop construction on private land within 20 miles of Lake Oahe. The company didn't respond to a request from The Associated Press for comment Sunday or Monday.
The corps statement comes after a federal appeals court ruling Sunday allowing construction to resume within 20 miles of the lake. The corps must still give its blessing for work on federal land bordering and under the lake, and officials say they're still reviewing whether there need to be reforms in considering tribal views on infrastructure projects.
The Standing Rock Sioux tribe opposes the pipeline.
North Dakota's congressional delegation and a laborers union are applauding a federal appeals court ruling allowing construction to continue on a small stretch of the four-state Dakota Access pipeline.
The ruling Sunday clears the way for pipeline work to resume within 20 miles of Lake Oahe in North Dakota. The pipeline is otherwise nearly complete.
The Laborers International Union says the ruling affirms that the pipeline is a lawfully permitted project.
Earthjustice attorney Jan Hasselman tells The Bismarck Tribune that continuing construction would be "a tragedy."
The Standing Rock Sioux Tribe is still appealing a court ruling that let work on the entire pipeline go forward. And federal agencies have prohibited construction on a section right at Lake Oahe where land is owned by the Army Corps of Engineers.
