- Confusion on the return postage for the Carbon County Detention Center Election: The instructions state that a first-class stamp (.55 cents) is required for the return postage (requirement from the MT Secretary of State’s Office). Carbon county is paying for the return postage on the detention center ballots! The county uses a postage machine – which means we receive a discount from the postal service! The post mark will be for .51 cents. The county had some return envelopes already stamped from last year that were not used – we added .01 cent stamp on these to comply with the current postage rates.
