(5) the name, profession and functions of the persons who prepared or revised the plan;
(6) a description and photographs of the condition of the site before the drilling;
(7) the method used to demonstrate that, prior to the permanent closure of the well or reservoir, no emanation at the surface vent has been observed over a period of 24 hours and no gas migration;
