LAC 56:V.513. Plugging and Sealing

A. The well or hold shall be filled or plugged upward from the bottom of the hole or well with neat cement or fill material, preferably in one continuous operation. Fill and/or plugging material shall not be poured into the hole or well. The commission may require under certain conditions, that the casing be perforated and cement forced under pressure into the surrounding formation to prevent movement of water in the annular space from one aquifer to another. Where the top of the casing is cut off below ground surface the excavation above the top of the casing shall be filled, after the surface plug is set, with enough soil or clay to compensate for compaction. All plugs shall be placed by the circulation or pump down method.
