AFFECTED WETLANDS 
[This page intentionally left blank] 
H-1 Appendix H

Table H-1 provides a description of the codes used in the Cowardin Classification System. Wetlands 

crossed by the Project are identified in table H-2 by Cowardin wetland codes and unique wetland ID. 

Table H-2 includes extra workspaces in the areas crossed by the pipelines. Wetlands affected by pipe 

storage yards, access roads, and aboveground facilities are listed at the end of the table.
