In the Arctic, Increased Vessel Traffic Brings Concerns Over Pollution
Pew recommends ways to limit discharge of garbage, sewage, other waste into sensitive ecosystem
While some of the vessels, which are led by large cargo ships, tugboats, and research ships, provide important services for people, science, and commerce, they also present serious and growing challenges, especially given that the traffic is forecast to continue increasing.
The health of this marine environment is inextricably connected to the way of life and cultural well-being of the region’s Indigenous peoples. The Bering Sea area has been an ecological, cultural, and economic center for Yup’ik, Cup’ik, St. Lawrence Island Yupik, and Inupiaq peoples for millennia. The northern Bering Sea also supports local commercial fisheries for herring, crab, halibut, and salmon.
Unfortunately, the rules that govern vessel waste management in the region are complex and vary greatly depending on ship type, size, place of origin, destination, and distance from shore.
A new analysis from The Pew Charitable Trusts, “Vessel Waste a Growing Challenge in the Northern Bering Sea and Bering Strait,” examines four major sources of waste discharged into the sea and provides the following recommendations for international, U.S., and Alaskan authorities to improve regulation, monitoring, and enforcement:
- Increase accountability for onboard trash record-keeping and enforce rules that limit garbage, particularly plastics, entering the water.
- Require that all vessels treat sewage to a high, consistent standard before discharging; prohibit releases of untreated sewage into the marine environment; and mandate more frequent monitoring, testing, and discharge reporting.
- Regulate grey water as a pollutant, similar to sewage, that must be treated on board before discharge.
- Prohibit oil and oily water discharges from ships in all northern Bering Sea waters.
This analysis provides valuable information and a resource for Alaskan coastal communities concerned with the health of the marine environment. The recommendations provide a starting point for Alaskans and international, federal, and state policymakers to work together to limit marine pollution in the vulnerable Arctic ecosystem.
