The Latest on developments in legal and state disputes involving the Dakota Access oil pipeline (all times local):
The company that built the four-state Dakota Access pipeline is negotiating with North Dakota regulators to try to resolve all investigations into potential wrongdoing.
The state Public Service Commission two weeks ago offered a settlement of allegations that Texas-based Energy Transfer Partners improperly reported the discovery of American Indian artifacts during construction.
Commission attorney Zachary Pelham says the company has responded to the offer with a counterproposal that includes potentially also resolving a state investigation into whether crews removed too many trees and improperly handled some removed soil while laying pipe in the state.
The commission met privately with attorneys Monday on the counterproposal and took no public action afterward. Attorneys for the two sides will continue to negotiate. The company could face fines in both cases.
A federal judge deciding whether to shut down the Dakota Access pipeline while more environmental review is done is allowing national energy trade groups to have a say.
Judge James Boasberg, in Washington, D.C., granted the request Friday, just days before Monday's final deadline for all parties involved in the legal dispute to submit arguments.
The $3.8 billion pipeline began moving North Dakota oil to Illinois June 1. But Boasberg later that month ordered federal officials to further review the pipeline's impact on the Standing Rock Sioux, one of four tribes continuing to fight in court.
The trade groups maintain that ceasing pipeline operations would seriously impact the oil industry.
Boasberg earlier approved a schedule for arguments that set Monday as the final deadline. His ruling could come any time after that.
