Abstract: The purpose of the Corps action is two-fold. First, the Corps is making provisions for future maintenance dredging at the POA. The Corps maintains navigation depths for the POA and other ports across Alaska as a part of the agency’s mission. The Corps has been maintaining Anchorage Harbor since 1965. Maintaining navigation depths is necessary for commercial and military operations at the Port of Anchorage. The POA serves 90 percent of the population of Alaska, handles 75 percent of goods shipped to Alaska, and is a strategic military and commercial seaport. Maintaining navigation at the port is essential to Alaska. The amount dredged to maintain the POA varies from year to year, with a maximum of about 2.1 million cubic yards dredged in 2004. The sedimentation rate at POA has increased in the last decade for reasons that are not fully understood. Table 1 shows dredging quantities since 1989. The site used for dredged material disposal now has been large enough for all the material dredged each year, but changes in local conditions could reduce capacity of that site. This EA addresses the need for a larger disposal site to allow for that possibility. The second purpose of the Corps of Engineers (Corps) action is to provide dredging support for MARAD's POA expansion in compliance with Section 118 of P.L. 108-447. The MARAD 2005 EA fully describes the purpose and need for POA expansion. This Corps EA addresses MARAD's dredging requirements and addresses, in more detail, alternatives to meet those requirements.
