American President Lines Ltd Harbour Facility, Seattle, Washington | Marine Utilities

American President Lines Ltd is a harbour facility located at 3443 W Marginal Way SW in Seattle, Washington, within King County. The facility is operational and serves as a key node in the maritime logistics chain, primarily handling containerized cargo for international trade. Its location on the Duwamish Waterway provides direct access to the Port of Seattle, one of the busiest container ports on the U.S. West Coast. As a container terminal, the facility operates under the regulatory framework of the U.S. Environmental Protection Agency's Vessel General Permit (VGP) and the Clean Water Act, which govern stormwater discharge and ballast water management. The facility's NAICS codes (483212 for Inland Water Freight Transportation and 488310 for Port and Harbor Operations) indicate its role in both waterborne freight and port services. Typical operations include container handling, storage, and intermodal transfer, with equipment such as ship-to-shore cranes and yard tractors. The facility's environmental significance lies in its proximity to the Duwamish River, a Superfund site, and the adjacent coastal habitat of Puget Sound. Stormwater runoff from container yards and potential oil-water separation from vessel operations are key environmental management concerns. The facility contributes to the regional economy by facilitating trade and supporting jobs in the maritime sector.

The facility is located on the Duwamish Waterway, which flows into Puget Sound, a sensitive coastal ecosystem. Container handling operations generate stormwater runoff that may contain pollutants such as heavy metals and hydrocarbons. The facility must comply with the EPA's Vessel General Permit and local stormwater permits to manage discharges. Proximity to urban Seattle also requires careful management of noise and air emissions from cargo handling equipment.
