PORT OF LONG BEACH - "Pier A West / Source Removal Action"
This project was a $73-million environmental cleanup of a 123-acre Port of Long Beach property known as Pier A West, which had been severely impacted by decades of oil production and use as a permitted disposal area for oil field-related waste before the site was acquired by the port. The key focus of the project (click here for the full report) was to protect the surrounding community, groundwater and adjacent harbor waters. The project met the goals of the port's Green Port Policy by employing sustainable design and construction practices, responding to community needs and reducing environmental impacts.
The project resulted in the excavation, treatment and disposal of more than 400,000 tons of solid waste and nearly three million gallons of contaminated groundwater. Numerous challenges were successfully addressed, including the site's below-sea-level elevation, the toxic and hazardous nature of the wastes, on-going oil field operations at the site, and the need for rigorous attention to the health and safety of workers and the surrounding community.
MARYLAND PORT ADMINISTRATION - "Masonville Dredged Material Containment Facility"
The Maryland Port Administration's Masonville Dredged Material Containment Facility is a 141-acre area within Baltimore Harbor, constructed to confine an estimated 15.4 million cubic yards of material from new navigation deepening work and maintenance dredging over the period 2010 to 2030. The project (click here for the full report) provided environmental enhancements, additional acreage for a future marine terminal facility and the foundation structures for a future Ro-Ro vessel-handing berth.
This $123 million project will allow MPA to provide dredged material placement capacity at Masonville beginning this year, 2010. The project is a key component of meeting MPA's need to place 1.5 million cubic yards of dredged material from its harbor deepening and maintenance activities. The project is notable for eliminating the port's need to purchase offsite burrow and the cost of hydraulic unloading of sand and gravel at its previous dredged materials containment facility.
