Excerpt:

The Navy has an ongoing cleanup program at sites throughout the former Naval Air Station (NAS) Alameda, also known as Alameda Point, in Alameda, California. This Fact Sheet provides information on one of these cleanup sites, including a description of the actions that will be taken to complete the cleanup.

The Navy is continuing with the cleanup for Installation Restoration (IR) Site 17, also known as Seaplane Lagoon (SPL). The cleanup will consist of removing sediments within the northwest (NW) corner of SPL that contain chemicals that may be harmful to human health or the environment. The sediments will be removed by dredging, which will begin in mid-to-late January 2012. The cleanup is being conducted in accordance with the National Oil and Hazardous Substances Pollution Contingency Plan (NCP) and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The sediment cleanup for SPL consists of the following: 1) dredging sediments in the NW corner of SPL; 2) conducting post-cleanup sampling to confirm the effectiveness of the cleanup; 3) dewatering the dredged sediments; 4) sampling the dewatered sediments to determine their waste characteristics; and 5) properly disposing of the sediments based on their waste characteristics.
