If there is any change in the original Notice of Intention, or if the operator plans to deepen, redrill, plug, or perform any operation that will permanently alter the well casing, a Rework/Supplementary Notice must be filed with the Division. A fee and/or bond may be required if, for example, the proposal concerns entering a plugged and abandoned or suspended well.

If the drilling operations the Division approved on a Rework/Supplementary Notice have not commenced one year from the date the notice is approved, the Division shall cancel the notice unless, prior to the expiration date, the operator requests a time extension on a Rework/Supplementary Notice. The Division may extend this time limit at its discretion.
