Conductor pipe or conductor casing shall be used for the purpose of supporting unconsolidated surface deposits. The use and removal of less than 40 feet of conductor pipe during the drilling of any oil or gas well shall be at the option of the operator. If such conductor pipe is to be pulled it shall be pulled prior to the cementing of the surface casing. All conductor casing shall have a cement seal at the surface preventing the possibility of any groundwater contamination and shall remain in the well if not pulled prior to the surface casing cement job. If more than 40 feet of conductor pipe was installed, the conductor pipe may not be pulled.
