Lauber Executive Summary The purpose of the Contaminant Assessment Process (CAP) is to compile and summarize known past, present, and potential contaminant issues on National Wildlife Refuges. The CAP has gath- ered information to help U.S. Fish & Wildlife Service personnel make informed management deci- sions about contaminant threats to Refuge lands and resources. Because of the extent of the Alaska Maritime National Wildlife Refuge and significant contamination of some areas, CAP reports for this Refuge cover units, subunits, or individual islands within the Refuge. This report documents known and potential contaminant issues on the Bering Sea Unit of the Alaska Maritime National Wildlife Refuge. Most people regard National Wildlife Refuges as pristine areas reserved for wildlife and fish. This unit of the Refuge includes biologically important remote islands whose coastal cliffs provide nesting habitat for millions of seabirds. Although managing these species is a primary manage- ment goal, the Refuge has, and continues to experience, a variety of other uses. These uses of the Alaska Maritime National Wildlife Refuge – Bering Sea Unit have included government agency and military use, commercial fisheries, and limited recreational use. These activities can result in contamination of trust resources and their habitats that require cleanup and remediation. Some former governmental activities left facilities and other remains on-site after operations ceased, often due to costs of materials removal, transport, and cleanup. At some sites, hazardous materials were spilled with no subsequent or inadequate cleanup. These concerns have been identified and highlighted in this CAP report. Cleanup of some of these sites is or has been conducted. Post-closure sampling conducted by others should be reviewed if there are sites that pose a potential continued risk to Refuge lands or resources. This Refuge unit has several contaminant issues that are highlighted in this report. The National Oceanographic and Atmospheric Administration (NOAA) operated numerous facilities on the Pribilof Islands, many of which had petroleum contamination problems. Most of these sites have undergone extensive cleanup actions. St. Matthew Island has Formerly Used Defense Sites (FUDS) that need additional site assessment. In addition, oil spills have had adverse effects on seabirds and their habitats throughout the Bering Sea Unit, and these spill risks are anticipated to likely increase in the future, should shipping and resource development increase as the result of continued climate change. Climate change could also cause unanticipated changes in contami- nant bioavailability. If and when any potentially contaminated lands are considered for conveyance to the Refuge, a full contaminant preacquisition assessment is required by existing Service and Department of the Interior policies. When warranted, preacquisition assessments should include rigorous sampling by (or funded by) the transferring land managers before the Service accepts any of these properties. Because of the potential for future oil spills both from vessels and land-based fuel storage facilities, spill response preparedness through spill contingency planning and participation in spill exercises is one way for the Refuge to prepare for such potentially damaging events. Collection of adequate baseline data prior to spill events is important for damage assessment efforts when spill incidents occur that affect Service trust resources. Baseline data will also be important to document present conditions as climate change progresses with its potential to complicate contaminant effects. ii Alaska Maritime National Wildlife Refuge – Bering Sea Unit Table of Contents 1.
