Members of the board of directors of the authority hold office for a term of four years, until a successor has been duly elected and qualified. If the office of any director becomes vacant by reason of the failure of any director elected at any election to qualify or for any other reason, the director’s successor must be appointed to fill the vacancy by the board of county commissioners of the county in which the vacancy occurs, or by the governing body of the city of Dickinson or Mandan, as appropriate. A director appointed to fill a vacancy shall hold office for the unexpired term of the director whose office has become vacant, and until a successor has been elected and qualified.

Members of the board of directors elected from a county must be elected at the primary election and assume office on the first Monday in July following their election. Members of the board of directors elected from the city of Dickinson or Mandan must be elected at the municipal election and assume office on the first Monday in July following their election.

In 2002 all directors’ terms are deemed to have expired, and each county shall elect one director to serve on the board of directors and the city of Dickinson shall elect two directors to serve on the board of directors. In 2002 one director from the city of Dickinson and directors from Adams, Billings, Dunn, Grant, Oliver, and Slope Counties must be elected for two-year terms and in 2004 and thereafter must be elected for four-year terms. In 2010 the director from the city of Mandan must be elected to a four-year term. All subsequent directors elected must be elected for four-year terms.

Before assuming the duties of the office of director, each director shall take and subscribe to the oath of office prescribed by law for civil officers. The authority treasurer must be bonded in an amount as the board may prescribe.
