North Slope GRS Public Information Homepage
This website describes the process used to develop Geographic Response Strategies (GRS) to protect sensitive coastal environments in the North Slope Subarea.
GRS’ are oil spill response plans tailored to protect a specific sensitive area from oil impacts following a spill. These response plans are map-based strategies that can save time during the critical first few hours of an oil spill response. They show responders where sensitive areas are located and where to place oil spill protection resources. These plans have been developed in other regions of Alaska and they can be reviewed here.
These oil spill response strategies will be part of the North Slope Subarea Contingency Plan. Alaska is divided into 10 regions and each region has a Subarea Contingency Plan that directs the state and federal actions in a response to the release of hazardous substances and oil spills. More information on these plans is available here.
The North Slope Subarea consists of the lands encompassed by the North Slope Borough extending from the Canadian boarder to Point Thompson. For the purpose of developing these geographic response strategies the subarea has been further divided into 2 zones, which are shown on the following map. Text links to the zones are listed below the map.

On each map sensitive areas have been identified and listed. A Site Selection Matrix has been developed that describes the resources at each of these candidate sites. This is available for review here and the key for the symbols is here. This is the first draft of the list of sites and other may be added to allow for additional input and reflect local concern. The areas that will receive a GRS may be selected from this list of candidate sites or other sites may be nominated.
The North Slope GRS Site Selection Process
A workgroup has been formed to develop GRS for the North Slope Subarea. Participants include Local, State and Federal agencies, spill response experts, oil spill contingency plan holders. The workgroup will select the sensitive sites that will have these strategies developed to protect in the event of an oil spill and review and approve the plans after they completed.
The first step in the GRS site selection process will be to identify candidate sites. Candidate sites are identified based on a set of three major site selection criteria.
risk of being impacted from a water borne spill; and
feasibility of successfully protecting the site with existing technology.
Public comments are also considered during site selection and the sites selected by the workgroup will consider this input. Once GRS site selection is finalized, the workgroup will develop strategies for each site.
The potential GRS locations identified in the site selection matrix were selected based on the following criteria of environmental sensitivity, which are set forth in the North Slope Subarea Plan:
Threatened and Endangered Species/Habitats
Subsistence Harvest Areas
Eel grass beds
Sheltered Tidal Flats
Sheltered Rocky Shores
Sea Lion Rookeries and Haulouts
Walrus Rookeries and haulouts
Large Seabird Colonies
Waterfowl and Shorebird Spring,Fall or Winter Concentration Areas
Large Anadromous Fish Streams
Intertidal Salmon Spawning Areas
Herring Spawning Areas
Federal Wilderness Areas, Wild and Scenic Rivers, and National Natural Landmarks
State Refuges, Sanctuaries, and Critical Habitat Areas
Cultural Resources/Archaeological Sites
High Use Commercial Fishing Areas
High Use Recreational Areas
Public involvement is essential to ensure that the sites selected and the strategies developed reflected the environmental protection priorities of local communities, stakeholders, and resource users. The workgroup welcomes public input to ensure that everyone with a stake in the North Slope Area is made aware of Geographic Response Strategies and their importance during an oil spill response.

Alaska Clean Seas Technical Manual (external link)
Alaska Clean Seas (ACS) is an Oil Spill Response Organization (OSRO) that provides ACS member companies with a unified response plan for spills in the North Slope oil fields. The Technical Manual grew out of the work of the Industry/Agency North Slope Spill Response Project Team, which consists of government and industry personnel representing the following organizations: Alaska Clean Seas, Alaska Department of Environmental Conservation, Alyeska Pipeline Service Company, ARCO Alaska, Inc. (now ConocoPhillips Alaska, Inc.), BP Exploration (Alaska) Inc., North Slope Borough, U.S. Coast Guard, U.S. Environmental Protection Agency, and U.S. Minerals Management Service.
As part of this effort, 212 priority protection sites were identified, and protective strategies were developed. The ACS Technical Manual describes these sites and protective tactics for each site. It is comprised of three documents:
Note: Due to the size of each manual it may take several minutes to open.
Please note that this is an external link and the response plans within were developed outside of ADEC's GRS development program.
