R647-2-114. Revised Notice

1. Minor additions or changes in the location of exploration operations do not require the submittal of a revised notice of intention. A new or revised Notice of Intention to Conduct Exploration (FORM MR-EXP) letter must be submitted when:

1.1. The proposed additions or changes will occur outside the originally designated legal subdivision; or

1.2. For exploration operations under 5 acres the proposed additions will cause the total unreclaimed surface disturbance to increase by more than 1 acre or exceed 5 acres; or

1.3. For exploration operations over 5 acres, the proposed additions or changes will cause an increase in the area of disturbance previously approved.

2. In the event the Division or the operator determine at the time a revision is submitted that the amount of the current surety does not accurately reflect the potential cost to complete reclamation at any particular point in time during the revised exploration operations, the Division may undertake a recalculation of the surety amount as provided in R647-2-111.3. If the recalculated amount is greater than the amount of the existing surety, the revised operations may not be implemented until a revised surety is filed with the Division.
