Legislative work

Our Spills Program is currently conducting studies, rulemaking, and engaging with partners under legislation from 2018 and 2019. This work focuses on reducing threats to southern resident killer whales and improving data analysis, safety of vessel traffic in the Salish Sea, and readiness to respond to spills of heavy oils.

Tug escort rulemaking

We will work with the Board of Pilotage Commissioners (BPC) to adopt rules requiring tug escorts for certain oil-laden vessels in Puget Sound.

Vessel risk modeling

We will develop and maintain a vessel traffic risk model to evaluate current and potential future oil spill risk.


Salish Sea Shared Waters Forum

The goal of these meetings is to work with our Canadian partners to address common issues in the Salish Sea related to oil spill prevention, preparedness, and response.


Synopsis of Vessel Activities

In 2019, the Legislature passed ESHB 1109, which directs Ecology’s Spill Prevention Program to produce a synopsis of current maritime vessel activity, navigation lanes, and anchorages.


Reporting requirements for crude oil movement by rail and pipeline

ESHB 1578 and ESSB 5579 expanded reporting requirements for regulated facilities, pipelines, and Ecology, and placed statutory limits on the vapor pressure of crude oil that can be loaded or unloaded into or from a rail tank car by facilities.


Vessel advance notice of transfer (ANT) updates

We require transfers of oil over water to be reported to our advance notice of transfer (ANT) IT system. Legislation requires new information be added on crude oil type, gravity, and region.

Contingency plan updates

In January 2019, we initiated rulemaking to update oil spill contingency plan standards in order to implement requirements for oils that may submerge or sink in water


Geographic response plan (GRP) updates

We've begun to update geographic response plans (GRPs) to identify water column and subsurface resources that could be harmed by oils that submerge or sink.


Spills Program Activity and Funding Report

We submitted the Activity and Funding Report to the Legislature on July 1, 2020. This report is published and can be found here: https://fortress.wa.gov/ecy/publications/summarypages/2008009.html
