In the third interview session, conducted on November 25, 1998, Sheets continues to discuss his work as special assistant to U.S. Senator Warren Magnuson, and speaks at length about the passage of the Northwest Power Act of 1980. He speaks about the history of public and private power utilities in the Pacific Northwest leading up to the passage of the act, particularly the Bonneville Power Administration and the Washington Public Power Supply System; and describes how the Northwest Power Act led to the creation of the Northwest Power Planning Council. He talks about other members of Magnuson’s staff, and about Magnuson’s unsuccessful 1980 re-election campaign.
