•SOP The top of the pipeline shall be placed not less than (desired 

 depth ) meters below the surface of existing canals and water- 

 ways, for a distance of ( desired distance ) meters on each side 

 of said canals and waterways. 



Line placement. 



S-28P Unless site conditions are shown to be totally unsuitable, the 

 "push-ditch" or "shove" method of pipeline installation shall 

 be utilized. 



S-29P To the greatest extent possible, installation of all flowlines, 

 supply lines, and utility lines shall be confined to existing 

 leveed roads or dredged canal rights-of-way. 



S-34P If flowlines must be placed through marsh, they should be laid 

 directly on the mash surface and allowed to sink, and settle 

 naturally. They should not be buried since vehicle movement as 

 well as digging and backfilling would result in further channel- 

 ization and marsh alterations. 



Backfilling. 



S-40P All pipeline ditches shall be completely backfilled with all 



available spoil removed during excavation operations such that 

 final surface contours approach original site conditions as 

 nearly as possible. In the event additional fill material is 

 required to compensate for settlement, it shall be removed from 

 scattered deep holes within the easement, rather than from con- 

 tinual surface cuts. 



Plugs along banks for pipeline ditches. 



S-33P Earthen marsh plugs shall be constructed at intervals of (de- 

 sired length ) meters along the pipeline and at the point of 

 intersection of the pipeline and major watercourses such as 

 lakes, ponds, bayous, canals, ditches, and tidal creeks. These 

 plugs shall extend a minimum of ( desired length ) meters on each 

 side of the pipeline ditch and shall be a minimum of ( desired 

 width ) meters wide and ( desired height ) meters high. They shall 

 be maintained by the permittee to the land manager's specifica- 

 tions.
