Aleutian Subarea - Places of Refuge
This website was used to assist the Aleutian Subarea Potential Places of Refuge Workgroup in the development of a document describing Potential Places of Refuge (PPOR) in the Aleutian Subarea. The initial project was completed in September of 2007 and was included in the Subarea Contingency Plan by the Aleutian Subarea Committee in 2009. In 2014, the Subarea Contingency Plan was updated and strengthened as a result of recommendations included in the findings from the Aleutian Islands Risk Assessment. At that time, additional information and changes to the PPOR were included in the documents to reflect new information in the subarea.
The Aleutian Subarea is depicted in the map shown below. Similar projects have taken place for the Prince William Sound, Kodiak and Cook Inlet Subareas. The workgroup record and products from those projects are available on the PPOR home page.
The objective of this project has been to identify docking, anchoring, mooring and grounding locations that may be selected as Potential Places of Refuge in order to enhance the overall response process.
The first map below depicts some of the risk factors the workgroup used in selecting potential places of refuge. Additional information on risks and vessel traffic in the Subarea has been developed by ADEC and the USCG and is available for viewing on the Aleutian Island Risk Assessment webpage. The workgroup identified candidate sites for potential places of refuge. These sites were researched and the resources and attributes of each were placed in a site assessment key. This summary of the resources at risk for each site aided in the selection potential places of refuge. The following links will download a copy of the site assessment matrix (PDF 81K) and the key (PDF 23K).
Download (PDF 5.4M) a printable copy of this map, which includes separate pages for each layer.
The large size of the Aleutian Subarea made it necessary to further divide it into smaller zones. These are illustrated in the Index Map shown above. Download (PDF 796K) a copy of this map.
Each zone then had an individual Potential Place of Refuge Plan developed. These 10 plans contain a map page that depicts the sites selected and informational page that contains important resource and operational information. These plans have been reviewed and approved by the workgroup and forwarded to the Subarea Contingency Plan Committee for inclusion in the Subarea Contingency Plan.

PPOR Introduction Section
Once these plans are included as a section to the Places of Refuge portion of the Subarea Contingency Plan, they will have an introductory section that will explain the context and use of the plans. You can download a copy of the introduction section (PDF 1.2M) to the Places of Refuge portion of the Subarea Contingency Plan. An associated project is the Aleutian Subarea Geographic Response Strategy (GRS) Project.

Invasive Species Considerations
Alien or invasive species include seeds, eggs, spores, or other biological material capable of propagating that species that is not native to an ecosystem. Invasive species commonly are transported in ballast waters and cargo associated oil transport and shipping. During operations any species that are encountered that are suspected to be non-native should be collected and presented to wildlife managers. Additional information on invasive species can be found in the “Useful Websites” section below.
