The National Petroleum Reserve in Alaska (NPRA) is an area of land on the Alaska North Slope owned by the United States federal government and managed by the Department of the Interior, Bureau of Land Management (BLM).[1] It lies to the west of the Arctic National Wildlife Refuge, which, as a U.S. Fish and Wildlife Service managed National Wildlife Refuge, is also federal land.
At a size of 23,599,999 acres (95,506 square kilometres; 36,875 square miles), the NPRA is the largest tract of undisturbed public land in the United States.[2] Iñupiat live in several villages around its perimeter, the largest of which is Utqiaġvik, the seat of the North Slope Borough. Due to the proximity of Inuit communities, drilling on the NPRA has sparked controversy revolving around the economic, ecological, and cultural importance of the land.[3]
The NPRA is an ecologically very important area for arctic wildlife; For birds, it has been called "Heathrow at the top of the world" with more birds in the NPRA than in the Arctic Wildlife Refuge.[4]
The NPRA is an ecologically very important area, and human settlements are small and rare.[5] For birds, it has been called "Heathrow at the top of the world" with more birds in the NPRA than in the Arctic Wildlife Refuge. [6] It contains Teshekpuk Lake, an important nesting ground for many species of migratory birds, including shorebirds and waterfowl. The NPRA supports the greatest population of aquatic birds out of any major Arctic wetland. The NPRA is a more populated habitat for aquatic bird populations than the Alaska National Wildlife Reserve, with a population of 5.4 million compared to 0.4 million.[7] The NPRA supports more than a half million caribou of the Western Arctic and Teshekpuk Caribou Herds. The Western Arctic Herd calves in the Utukok, Kokolik and Colville uplands, while the Teshekpuk Herd calves in the areas surrounding Teshekpuk Lake. The highest concentration of grizzly bears in Alaska's Arctic, as well as wolverines, and wolves prey on the abundant caribou.[8] The caribou are utilized for subsistence hunting by local hunters.[9] The area is also a habitat for maternal denning of polar bears in the winter. Denning and the associated habitat is essential for newborn cub development.[10]
NPRA contains the headwaters and much of the Colville River, Alaska's largest river north of the Arctic Circle. The region's geology is unique in Alaska and most of the area remained glacier free throughout the last ice age.[5]
The NPRA was created by President Warren G. Harding in 1923 as Naval Petroleum Reserve Number 4 during a time when the United States was converting its Navy to run on oil rather than coal.[1][5] In 1976 the Naval Petroleum Reserves Production Act (NPRPA) renamed the reserve the "National Petroleum Reserve in Alaska" and transferred it from the Navy to the Department of the Interior.[1][11]: 36 The 1980 Interior Department Appropriations Act directed the Bureau of Land Management (BLM) within the Department of Interior to conduct oil and gas leasing. Nevertheless, the area was left essentially as a wilderness until the late 1990s.[2]
The NPRPA also contains provisions that apply to any exploration or production activities within areas "designated by the Secretary of the Interior containing any significant subsistence, recreational, fish and wildlife, or historical or scenic value".[12]: 5–6 Based on this authority, the Secretary in 1977 designated three Special Areas within the NPRA in which all activities were to "be conducted in a manner which will assure the maximum protection of such surface values to the extent consistent with the requirements of this Act for the exploration of the reserve." The Teshekpuk Lake Special Area was created to protect migratory waterfowl and shorebirds. The Colville River Special Area was created to protect the arctic peregrine falcon, which at that time was an endangered species. The Utukok River Uplands Special Area was created to protect critical habitat for caribou of the Western Arctic Herd. The Secretary of the Interior enlarged the Teshekpuk Lake and Colville River Special Areas in the Northeast NPRA Record of Decision of 1998.[12][13] In 2003, a committee of the National Research Council published a report that urged caution in granted oil and gas leases, in that that oil and gas extraction in the reserve may cause permanent and irreversible environmental damage.[8] In 2004, the Secretary created the Kasegaluk Lagoon Special Area.[12]
Between 1944 and 1981, the US government drilled and then abandoned about 137 wells in the reserve as part of an exploratory oil and gas program in order to obtain estimates and locations of reservoirs. BLM operates the abandoned wells.[14]: 3–4 [15] In 1998, after BLM had gone through a planning process to create an "Integrated Activity Plan/Environmental Impact Statement" for the Northeast area, the Secretary of Interior signed a Record of Decision (ROD), which opened 87 percent of this area to oil and gas leasing[2] and the first leases were signed in 1999.[16] A ROD for the Northwest area was signed in 2004.[2] BLM began the planning process for the South in 2005.[2] The 2003 USGS survey had indicated the best prospects for large reserves were just east of Teshekpuk Lake - a Special Area in the Northeast[5] and in 2006 the Bush administration attempted to lease land in the habitat around Teshekpuk Lake. Six conservation groups sued to prevent the leases and won.[17] The litigation forced BLM to create a new plan for the entire reserve. The final ROD for the entire region, including the South, was signed by the Secretary in February 2013.[2]
As of October 2012, a total of 1,374,583 acres (556,274 ha) have been leased; 872,125 acres (352,936 ha) in the Northeast region, and 502,458 acres (203,338 ha) in the Northwest region.[18]
In March 2012, the Alaska House and Senate passed legislation urging the Bureau of Land Management to plug the abandoned wells from the US government exploratory program; the resolution said just seven wells have been properly plugged and reclaimed and that the wells are an eyesore and are harming the environment.[15]
An assessment by the United States Geological Survey (USGS) in 2008[19] estimated that the amount of oil yet to be discovered in the NPRA is only one-tenth of what was believed to be there in the previous assessment, completed in 2002.[20] The 2008 USGS estimate says the NPRA contains approximately "896 million barrels of conventional, undiscovered oil".[20] The reason for the decrease is because of new exploratory drilling, which showed that many areas that were believed to hold oil actually hold natural gas.
The estimates of the amount of undiscovered natural gas in the region also fell, from "61 trillion cubic feet of undiscovered, conventional, non-associated gas" in the 2002 estimate, to 53 trillion cubic feet (1,500 km3) in the 2010 estimate.[20]
Oil and gas leases are authorized under the National Petroleum Reserves Production Act of 1976. ConocoPhillips was issued leases in 1999.[3]
On March 13, 2023 the Biden Administration approved the Willow Project, allowing leases for oil company ConocoPhillips to drill on the NPR-A.[9] The project approval came after Biden established he would not allow more drilling on federal lands, making some supporters angry, while others had been pushing for the project’s approval.[9] Willow Project development will include the construction of a gravel mine, hundreds of miles of roads, pipelines, and a facility for processing the oil. This development will occur in the Arctic tundra and wetlands.[9] Due to the disruption to the North Slope environment, it has incited a legal battle from environmental groups opposing drilling.[3]
Alaskan communities also heavily rely on the oil industry for local economies. Debates over whether to welcome oil development into the community or not have caused divide.[21] Numerous Iñupiat members have voiced support for the Willow Project because, it creates many jobs and a source of revenue. Doreen Leavitt, Director of Natural Resources for Iñupiat Community of the Arctic Slope describes the Willow Project as an economic “lifeline” for North Slope communities.[22] Opponents counter argue that the economic benefits will only be viable in the short-term while the environmental consequences will be long-term.[3]
Native Alaskan communities reside on the North Slope and are impacted by both the effects of past drilling projects and the threat of future projects.[3] The community of Nuiqsut, which is majority Iñupiat, has found oil extraction hinders their subsistence practices. This threatens their cultural ties to the land.[23] Oil extraction also results in degradation of the region’s air quality.[9] Local communities including the Utqiagvik have faced impacts from petroleum spills such as polycyclic aromatic hydrocarbon (PAH) contamination.[24] In 2012 the Repsol blowout from an exploration well left residual pollution impacting the local Nuiqsut residents.[23] Nuiqsut mayor Rosemary Ahtuangaruak expresses concern with oil extraction in the North Slope and how “communities in the Arctic are left to contend with the health impacts of pollution as well as the devastation that comes from dramatic changes to the land like sea ice melt, permafrost thaw, and coastal erosion.”[22]
Drilling has also sparked controversy from environmental groups due to its ecological impacts. Research has shown a number of impacts drilling has on the North Slope environment. These include:
