(AP) A company building a natural gas pipeline across southwest Washington's White Salmon River says construction will be completed this month, even as a Native American tribe seeks a halt to the project.

The Yakama Nation claims the pipeline will hurt a culturally significant archaeological site. The tribe has asked the Federal Energy Regulatory Commission to halt the construction.

Williams-Northwest Pipeline says it has been in frequent community with the tribe about the project and believes it has acted in good faith to follow required regulations. The company says it has consulted with the U.S. Fish and Wildlife Service, the Washington Department of Archaeology and Historic Preservation, and two other Indian tribes about the project.

The company is replacing a pipeline that sits upstream of the former Condit Dam.
