AI Analysis
This bill tightens escort requirements for oil tankers and oil-carrying barges in Puget Sound and adjacent waters, especially east of the Discovery Island–New Dungeness line. It lowers the size threshold for mandatory escort from 125,000 to 40,000 deadweight tons and specifies minimum tug power based on tanker size.
- Prohibits oil tankers over 125,000 deadweight tons from sailing east of a line from Discovery Island light to New Dungeness light, unless authorized by the U.S. Coast Guard.
- Requires oil tankers between 40,000 and 125,000 deadweight tons to be escorted by tugboats with at least 3,000 shaft horsepower or 5% of the tanker’s deadweight tons (whichever is greater) when operating east of the Discovery–New Dungeness line and in Puget Sound.
- Requires smaller oil tankers (5,000–40,000 deadweight tons) and certain oil-carrying barges to be escorted by tugs with at least 2,000 shaft horsepower (equal to 5% of a 40,000-deadweight-ton tanker) when operating in Rosario Strait and connected waterways east of the main Puget Sound area.
- Exempts tankers in ballast or unladen, vessels providing bunkering/refueling services, and towed general cargo deck barges from escort requirements.
- Allows the Board of Pilotage Commissioners to adjust or suspend escort requirements by rule, consistent with existing law.
Who is affected
- Large oil tankers (over 125,000 deadweight tons) — Oil tankers over 125,000 deadweight tons are banned from sailing east of a line between Discovery Island and New Dungeness unless authorized by the U.S. Coast Guard.
- Medium-sized oil tankers (40,000–125,000 deadweight tons) — Oil tankers between 40,000 and 125,000 deadweight tons must be escorted by tugboats with sufficient power (at least 3,000 shaft horsepower or 5% of the tanker’s deadweight tons, whichever is greater) to operate east of the Discovery–New Dungeness line and in Puget Sound.
- Smaller oil tankers and certain oil-carrying barges (5,000–40,000 deadweight tons) — Smaller oil tankers (5,000–40,000 deadweight tons) and certain oil-carrying barges must be escorted by tugs with power equal to at least 5% of a 40,000-deadweight-ton tanker (i.e., 2,000 shaft horsepower) when operating in Rosario Strait and connected waterways east of the main Puget Sound area.
- Regulators and federal authorities (Board of Pilotage Commissioners, U.S. Coast Guard) — The Board of Pilotage Commissioners may adjust or suspend escort requirements by rule, and the U.S. Coast Guard retains authority to authorize exceptions for large tankers.
Pro/Con Analysis
Potential Benefits (5)
Banning large oil tankers (>125,000 DWT) from sensitive eastern Puget Sound waters directly protects communities in the San Juan Islands, Bellingham, and Tacoma from the most severe spill risks — including loss of life, displacement, and long-term environmental damage.
Public SafetyPeopleRef: Sec. 1(2)(a)(i)Lowering the escort threshold from 125,000 to 40,000 DWT and requiring minimum 2,000 SHP tugs in Rosario Strait significantly expands coverage to smaller but still hazardous vessels — protecting critical salmon migration routes, shellfish beds, and tribal treaty rights to natural resources.
EnvironmentPeopleRef: Sec. 1(2)(a)(ii)(A)-(B)Authorizing the Board of Pilotage Commissioners to adjust escort rules by rule (not legislation) allows responsive, science-based updates to tug requirements as new vessel designs, traffic patterns, or spill response capabilities emerge — supporting adaptive management for local port and coastal agencies.
Local GovernmentPeopleRef: Sec. 1(2)(a)(ii)(C)While increasing operational costs for tanker operators, the bill may create new jobs in tugboat services and maritime support industries in ports like Anacortes, Tacoma, and Everett — though these gains may be offset by reduced tanker traffic.
Business & EmploymentPeopleRef: Sec. 1(2)(b)Exempting bunkering/refueling vessels from escort requirements avoids unnecessary disruption to essential marine fuel supply chains — but this exception carries some spill risk if not carefully monitored by Coast Guard oversight.

Potential Concerns (5)
Mandatory escort for medium and large oil tankers (40,000–125,000 DWT) east of Discovery Island–New Dungeness line increases tug availability and response capacity in case of grounding or collision, reducing risk of oil spills that could contaminate drinking water, fisheries, and shorelines used by communities.
Public SafetyPeopleRef: Sec. 1(2)(a)(i)Extending escort requirements to smaller tankers (5,000–40,000 DWT) and oil-carrying barges in Rosario Strait — a high-traffic, ecologically sensitive corridor — reduces spill risk in areas where emergency response is logistically challenging and where many small communities rely on subsistence fishing and clean water.
Public SafetyPeopleRef: Sec. 1(2)(a)(ii)(A)-(B)Prohibiting tankers over 125,000 DWT east of the Discovery–New Dungeness line eliminates the highest-risk vessels from the most congested and ecologically sensitive parts of Puget Sound, significantly lowering the probability of a catastrophic spill affecting salmon habitats, orcas, and coastal ecosystems.
EnvironmentPeopleRef: Sec. 1(2)(a)(i)Exempting vessels in ballast or unladen from escort requirements weakens safety protections, as empty tankers are still vulnerable to wind, current, and mechanical failure — and a collision or grounding in ballast can still cause structural damage that leads to future spills when reloaded.
Public SafetyPeopleRef: Sec. 1(2)(b)Excluding towed general cargo deck barges from escort requirements may create a loophole, as some such barges carry non-oil hazardous materials or may be used to transport petroleum products in bulk despite the narrow definition — potentially undermining the bill’s spill-prevention goals.

Who Is Most Affected
Indigenous tribes with treaty-reserved fishing and cultural rights in Puget Sound (e.g., Suquamish, Tulalip, Muckleshoot) benefit strongly: reduced spill risk protects salmon, shellfish, and cultural resources vital to their economy and identity.
Small commercial fishing and tourism operators (e.g., charter boats, oyster farms) benefit from reduced spill risk and protection of marine habitats — but may face higher fuel or shipping costs if tankers reroute or reduce frequency.
Large oil shipping companies (e.g., tanker operators, terminal owners) will face higher operational costs due to mandatory tugs and potential route restrictions — though some may pass costs to shippers or customers.
Coastal communities (e.g., San Juan County, Island County, Tacoma) benefit from reduced environmental and public health risks — especially those dependent on tourism, fisheries, and drinking water from Puget Sound.
Tugboat operators and maritime service providers may see increased demand for escort services — but may also face higher compliance costs (e.g., vessel upgrades, staffing) and possible consolidation of the industry.
