Tug Escort Rulemaking

2019 Legislation - ESHB 1578

The 2019 Legislature enacted new safety requirements to close the safety gap further on the acute risk of a potentially large oil spill in the Salish Sea from tank vessels by passing Engrossed Substitute House Bill 1578 Reducing threats to southern resident killer whales by improving the safety of oil transportation. 


ESHB 1578 requires in Rosario Strait and connected waterways east, as of September 1, 2020, tug escorts on laden oil tankers between 5,000 and 40,000 deadweight tons, and on both laden Articulated Tug Barges (ATBs) and towed waterborne vessels or barges that are 1) designed to transport oil in bulk internal to the hull, and 2) greater than 5,000 deadweight tons.

For the September 1, 2020 implementation of tug escorts in Rosario Strait and connected waters east, the BPC adopted an interpretive statement regarding terms in ESHB 1578. ESHB 1578 also gave the BPC authority to partner with the Department of Ecology on this work.
