The owners of such rejected weights and measures shall cause them to be made correct within 30 days or such longer period as may be authorized by the rejecting authority; or, in lieu of correction, the owners may dispose of the rejected weights and measures, but only in such manner as is specifically authorized by the rejecting authority.
