Any operator who registers with the director two or more surface mining sites may elect, at the time the second or any subsequent site is registered, to post a single bond in lieu of separate bonds on each site. The amount of a single bond on two or more surface mining sites may be increased or decreased from time to time in accordance with K.S.A. 49-609, 49-613 and 49-615. When an operator elects to post a single bond in lieu of separate bonds previously posted on individual sites, the separate bonds shall not be released until the new bond has been accepted by the director.
