This report was prepared to determine whether the Trans-Alaska Gas System (TAGS) is compatible with other pipelines, such as Trans-Alaska Pipeline System and the Alaska Natural Gas Transportation System. Compatibility implies that construction, operation, and maintenance of TAGS will not interrupt or impair the operation and maintenance of these other pipelines in an unreasonable manner. The report is in response to Yukon Pacific Corporation's filing on December 5, 1986 for an amended right-of-way application for the construction of a pipeline from Prudhoe Bay to Port Valdez.

An environmental impact statement for the proposal by Yukon Pacific Corporation to build a 796.5 mile long buried, chilled, high pressure natural gas pipeline from Prudhoe Bay to Anderson Bay, Alaska. The project is called Trans-Alaska Gas System (TAGS).
