This bill amends RCW 88.16.190 to establish new operational requirements for oil tankers in restricted waters of Washington State. Specifically, it prohibits oil tankers over 125,000 deadweight tons from proceeding beyond a designated point without authorization from the U.S. Coast Guard. Additionally, it sets conditions for oil tankers between 40,000 and 125,000 deadweight tons to operate in certain waters, requiring them to be escorted by tugs with a minimum aggregate shaft horsepower of either 3,000 or five percent of the tanker’s deadweight tons, whichever is greater. The bill also introduces provisions for smaller oil tankers and barges, specifying escort requirements based on their deadweight tonnage.

Furthermore, the bill clarifies definitions related to oil tankers, articulated tug barges, and towed vessels, ensuring that certain vessels, such as those providing bunkering services or those under specific tonnage thresholds, are exempt from the escort requirements. The amendments also adjust the tonnage figures for various categories, including raising the threshold for certain operational requirements and clarifying the definitions of relevant vessels. Overall, the bill aims to enhance safety and environmental protection in Washington's navigable waters by regulating the operation of oil tankers and related vessels.
