Matson Navigation Company Maunaloa - Container Harbour in Honolulu, Hawaii

Matson Navigation Company Maunaloa is an operational harbour facility situated at Pier 51 on Sand Island Access Road in Honolulu, Hawaii. As part of the Matson Navigation Company, it plays a critical role in containerized cargo shipping between the U.S. West Coast and Hawaii, supporting the state's supply chain and economy. The facility operates under U.S. federal regulations including the Clean Water Act and the Vessel General Permit (VGP) for discharges incidental to vessel operations. As a container terminal, it handles a high volume of TEUs annually, with typical throughput for a major Hawaiian port ranging from 100,000 to 300,000 TEUs per year. The facility likely employs modern cargo handling equipment and stormwater management systems to mitigate environmental impacts. Located on Sand Island in Honolulu Harbor, the facility is adjacent to sensitive coastal ecosystems. Its operations are significant for Hawaii's import-dependent economy, handling essential goods such as food, construction materials, and consumer products. The facility's proximity to urban Honolulu necessitates careful management of noise, air emissions, and water quality to minimize impacts on the surrounding community and marine environment.

The facility is located on Sand Island within Honolulu Harbor, an area with sensitive coastal habitats including coral reefs and seagrass beds. Container shipping operations generate potential risks from stormwater runoff, oil spills, and invasive species introduction via ballast water. The facility must comply with the Vessel General Permit (VGP) and state water quality standards to manage these risks.
