Pipeline Construction Methods by Milepost 

The anticipated primary construction methods that will be used along the KMLP Project 

are listed by milepost in the following tables (minor construction methods, such as road, 

railroad, and pipeline crossings are not listed). The construction method numbers used in 

the table correspond to the construction method descriptions as follows: 

• Typical Submerged Marsh (Push-Pull); 

• Typical HDD Waterbody Crossing; 

• Typical Inland Open Water <8’ Depth; 

• Saturated Wetland Crossing without Topsoil Segregation; 

• Typical Cross Section with 42” Pipe Adjacent to Foreign Pipeline without Topsoil 

Segregation; 

• Upland without Topsoil Segregation; 

• Typical Cross Section with 24” Pipe Adjacent to Foreign Pipeline without Topsoil 

Segregation; 

• Unsaturated Wetland Crossing with Topsoil Segregation; 

• 42” Typical Cross Section with Full Width Topsoil Segregation; 

• Typical Cross Section with 42” Pipe Adjacent to Foreign Pipe with Ditch Plus 

Spoil Side Topsoil Segregation; 

• 42” & 36” Typical Cross Section without Topsoil Segregation; 

• 36” Typical Cross Section without Topsoil Segregation; and 

• Inland Open Water ≥8’ Depth.
