d/
a/ Stream width at intersection with pipeline; for purposes of this analysis, all stream crossing widths are assumed to be at least 1 foot wide.
b/ Crossing footage varies by method; an additional 40 feet is required for conventional bore (5 feet for the bore pit and 15 -foot wide stream buffer on each side of
stream); HDD crossings lengths are 100 feet per each inch of pipeline diameter due to pipe bending constraints.
c/ See table of Cost Comparison by Method at end of this appendix.
d/ Slope was calculated based on average slope change within 30 feet of stream crossing. WOTUS = Waters of the United States
e/ Identified crossing by agencies for a previously known occurrence federally listed threatened or endangered ('T&E") species based on agency correspondence
to date.
f/ Private wells (known to date) within 150 feet of a resource crossing
g/ Cost effectiveness test: cost greater than 300 percent of open cut crossing method is considered not practicable.
h/ Cost ratio relative to open -cut crossing method.
i/ See practicable logic test for various conditions by crossing method at the end of this appendix for details A method is considered practicable if all variables are
practicable; methods practicable for all variables except for presence of aquatic T&E species are classified as practicable with time of year ('TOY") crossing
restrictions.
j/ If the Project moves forward with alternative crossing method that is not practicable, it is due to the request of a regulatory agency that does not consider
practicability.

a/ Wetland width at intersection with pipeline; for purposes of this analysis
b/ Crossing footage varies by method; an additional 40 feet is required for conventional bore (5 feet for the bore pit and 15 -foot wide stream buffer on each
side of stream); HDD crossings lengths are 100 feet per each inch of pipeline diameter due to pipe bending constraints.
c/ See table of Cost Comparison by Method at end of this appendix.
d/ Slope was calculated based on average slope change within 30 feet of wetland crossing. WOTUS = Waters of the United States
e/ Identified crossing by agencies for a previously known occurrence federally listed threatened or endangered ("T&E") species based on agency
correspondence to date.
f/ Private wells (known to date) within 150 feet of a resource crossing
g/ Cost effectiveness test: cost greater than 300 percent of open cut crossing method is considered not practicable.
h/ Cost ratio relative to open -cut crossing method.
i/ See practicable logic test for various conditions by crossing method at the end of this appendix for details A method is considered practicable if all
variables are practicable; methods practicable for all variables except for presence of aquatic T&E species are classified as practicable with time of year
("TOY') crossing restrictions.
j/ If the Project moves forward with alternative crossing method that is not practicable, it is due to the request of a regulatory agency that does not consider
practicability.
