USDOT Alpine Pipelines Spectacled Eider Survey, June 2011

The U.S. Department of Transportation, Office of Pipeline Safety (USDOT), has designated much of the Arctic Coastal Plain of Alaska that is currently occupied by oil and gas infrastructure as an Unusually Sensitive Area (USA) for Spectacled Eiders (Somateria fischeri), a threatened species under the Endangered Species Act (ESA). The USA designation affects the USDOT-regulated pipelines in the region including Badami, Endicott, North Star, Prudhoe Bay NGL, Milne Point, Kuparuk, Oliktok, Alpine, and the Trans-Alaska Pipeline. Four DOT-regulated lines are operated by ConocoPhillips Alaska, Inc. (CPAI), in the Kuparuk River and Colville River units (Figure 1). These consist of the Oliktok Pipeline, Kuparuk Pipeline (including the Kuparuk Extension), Alpine Oil Pipeline, and the portion of the Alpine Arctic Heating Fuel Pipeline under the Colville River. As part of the Pipeline Integrity Management Plan, CPAI instituted surveys in 2004 for threatened eiders within a corridor along the USDOT Alpine Oil and the Arctic Heating Fuel pipelines (hereafter, the Alpine Pipelines) between the Alpine facilities on the Colville River delta and Central Processing Facility 2 (CPF-2) in the Kuparuk Oilfield; the other USDOT pipelines in the Kuparuk Oilfield area have been covered by annual aerial surveys for pre-nesting eiders since 1993 (Stickney et al. 2011). CPAI contracted with ABR, Inc., to conduct an aerial survey for pre-nesting eiders along the Alpine Pipelines during June 2011 and to conduct ground surveys for nests if any Spectacled Eiders were seen during the aerial survey, as directed by the U.S. Fish and Wildlife Service.
