Current through Register Vol. 24-14, July 15, 2024
(1)
				The salmon vulnerability ranking is based on seasonal habitat preference of
				juveniles during outmigration, adults as they return to spawn and the presence
				of oil in river mouths during peak occurrence of salmon runs. The salmon
				vulnerability ranking was developed from existing information and
				determinations of the salmon subcommittee of the scientific advisory board. In
				the case of Chinook salmon, habitat preference differs for subyearlings and
				yearlings.
(2) The vulnerability of
				five salmon species in nine habitats are relatively scored for vulnerability to
				oil spills on a 1 to 5 scale for each season, where 5 represents the most
				vulnerable condition, and a score of 1 represents the least vulnerable
				condition, as follows:
