(4) effects on and service to adjacent communities and potential intermodal transportation connections;
(5) environmental concerns;
(6) use of public land to the maximum degree possible;
(7) minimization of probable construction costs;
(8) the location of and the opportunity to obtain access to identified natural resources that could contribute significantly to the economic development of the state and Canada;
(9) avoidance of possibly unstable ground due to thawing of frozen soils; and
(10) prior and established traditional uses.
