Reservation, the nuclear facility along the Columbia River in Benton County produced plutonium. The site, established in 1943 to provide support for the Manhattan Project, operated from World War II through the Cold War. Decades of production of plutonium resulted in millions of gallons of high-level radioactive waste. In 1989, the Washington State Department of Ecology along with the EPA and the US Department of Energy (DOE) entered into the Tri-Party Agreement, which sets targets, or milestones, for cleanup. Centennial Accord Following the contentious US v Washington case related to Native American fishing rights, commonly known as the “Boldt Decision,” Gardner undertook to build more lasting, friendly relationships with Washington's Native American tribes. The Accord served to bring parties to the table to negotiate their shared interests. Gregoire played a principal role in helping reach agreements about the natural resource distribution between the tribes and the state. Attorney General of Washington Gregoire was elected attorney general in 1992 by 11 percentage points over her opponent, Norm Maleng, an attorney who served and was reelected seven times as King County prosecutor. She was Washington's first and only female attorney general. Gregoire was reelected in 1996 and 2000, both times over Richard Pope, by about 25 and 18 percentage points respectively. As attorney general, Gregoire worked on children's issues, helped reform the juvenile system, passed a new ethics law for state government, strengthened rights for victims of identity theft, and worked to find alternatives to litigation in resolving legal disputes.

Multiple private suits stemming from a 1950s study in the British Medical Journal linked smoking to lung cancer and heart disease. Attorneys General on June 20, 1997, led by Gregoire negotiated a settlement that required tobacco companies to pay more than $206 billion over 25 years in reimbursements to the states for tax dollars spent to treat Medicaid patients for smoking-related illnesses. The companies also agreed to pay $50 million to national attorneys general for enforcement. These payments funded children's health services and programs and a $25 billion trust for health-related issues. For her leading role in the litigation, Gregoire won the state of Washington a $4.5 billion share of the settlement over the next 25 years with the payments continuing
