Tentative Interim Amendments

Tentative Interim Amendments (TIAs) are proposals to add or delete text immediately from the Code. To accomplish this, any interested party must submit a proposal indicating the proposed change along with their substantiation divided into two parts; the first part indicating the technical merits of the proposed changed followed be a statement as to the emergency nature of the proposal.
