If, on expiry of the time limit referred to in the previous article, the owner of the buildings has not taken the necessary measures to dismantle and restore the site as provided for in article R. 754-2, the prefect may take the following measures against the owner:
1° Require a sum corresponding to the estimated cost of the work or operations to be carried out to be deposited with a public accountant within a period specified by the prefect.
This sum will be recovered in the same way as for government debts not related to taxes or property.
The sum deposited will be returned to the public accountant.
The sum deposited shall be returned, where applicable, as and when the work or operations are carried out, and at least every three months;
2° Carry out the prescribed measures on its own initiative, in the place and at the expense of the person served with the formal notice.
Where 1° is applied, the sum deposited is used to pay the expenses incurred. Any balance remaining shall be returned within three months of completion of the dismantling and restoration operations.
