All five previous board members were recalled during the May election.
The county commissioners will review applications and appoint three new members to the Gardiner Sanitary board. Those three selected will then appoint the final two board members.
To serve on the board, you must own property or be a registered voter living in the district.
Those interested can get an application at the commissioners office at the courthouse or on the county website. Applications must be turned in by Monday July 7 at 5 p.m.
