Port Mackenzie Rail Extension Biological Assessment

November 25, 2009

This Biological Assessment addresses potential effects of the Alaska Railroad Corporation’s proposed Port MacKenzie Rail Extension on federally listed threatened and endangered species that are protected under the Endangered Species Act.

After consulting the U.S. Fish and Wildlife Service and NOAA Fisheries on potential threatened or endangered species that could be affected by the proposed project, the Surface Transportation Board Section of Environmental Analysis determined that the proposed project could indirectly affect the endangered Cook Inlet beluga whale (Delphinapterus leucas).

SEA, in consultation with NOAA Fisheries, did not identify any direct impacts from the proposed project to the beluga whale or beluga whale habitats in the waters of Cook Inlet or within the lower reaches of the Susitna River or the Little Susitna River.
