Arctic National Wildlife Refuge (ANWR):
New Directions in the 110th Congress
Summary
One part of the ongoing energy debate has been whether to approve energy
development in the Arctic National Wildlife Refuge (ANWR) in northeastern Alaska
— and if so, under what conditions — or whether to continue to prohibit
development to protect the area’s biological, recreational, and subsistence values.
ANWR is rich in fauna, flora, and oil potential. Its development has been debated for
over 40 years, but sharp increases in energy prices from late 2000 to early 2001,
terrorist attacks, more price increases in 2004-2008, and energy infrastructure damage
from hurricanes have intensified debate. Few onshore U.S. areas stir as much industry
interest as ANWR. At the same time, few areas are considered more worthy of
protection in the eyes of conservation and some Native groups. Current law explicitly
prohibits oil and gas leasing in the Refuge.
Changes in party control in the 110th Congress encouraged those who seek
wilderness protection for this portion of ANWR. However, any change from the
status quo appears just as difficult for proponents of wilderness designation who seek
to provide additional statutory protection as it did for development advocates in the
109th Congress.
As gasoline prices increased, those Members who advocate increasing supplies
as a method of lowering energy prices have renewed their focus on ANWR
development as one response to the increase. However, opponents of opening the
Refuge have succeeded in stopping these attempts. In the first session of the 110th
Congress, the House rejected a motion to recommit H.R. 3221 to the Energy and
Commerce Committee with instructions that it be reported back with language
authorizing ANWR development. In the second session, the House rejected a motion
to adjust budget levels to assume increased revenues from opening ANWR to
development. Also in the second session, the Senate rejected an amendment (S.Amdt.
4720) to S. 2284 to open ANWR to energy development.
Development advocates argue that ANWR oil would reduce U.S. energy
markets’ exposure to Middle East crises; lower oil prices; extend the economic life
of the Trans Alaska Pipeline; and create jobs in Alaska and elsewhere in the United
States. They maintain that ANWR oil could be developed with minimal
environmental harm, and that the footprint of development could be limited to a total
of 2,000 acres. Opponents argue that intrusion on such a remarkable ecosystem
cannot be justified on any terms; that economically recoverable oil found (if any)
would provide little energy security and could be replaced by cost-effective
alternatives, including conservation; and that job claims are exaggerated. They
maintain that development’s footprints would have a greater impact than is implied
by a limit on total acreage. They also argue that limits on footprints have not been
worded to apply to extensive Native lands in the Refuge, which could be developed
if the Refuge were opened.

Arctic National Wildlife Refuge (ANWR):
New Directions in the 110th Congress
Most Recent Developments
On May 13, 2008, the Senate rejected the McConnell amendment (S.Amdt.
4720) to S. 2284 to open ANWR to energy development (42-56, Roll Call #123). On
May 14, 2008, the House rejected a motion to adjust budget levels to assume
increased revenues from opening ANWR to leasing and exploration (185-229, Roll
Call #321). The President’s FY2009 budget assumed legislation to open ANWR to
development, and that the recoverable oil would be between 5.7 and 16 billion barrels.
It assumed that the first sale would be held in FY2009, and would generate $7 billion
in new revenues, to be shared equally with the state of Alaska. Rising gasoline prices
during 2008 intensified interest in opening ANWR to development.
Background and Analysis
The Arctic National Wildlife Refuge (ANWR) consists of 19 million acres in
northeast Alaska. It is administered by the Fish and Wildlife Service (FWS) in the
Department of the Interior (DOI). Its 1.5-million-acre coastal plain is viewed by
development proponents as one of the most promising U.S. onshore oil and gas
prospects. According to the U.S. Geological Survey (USGS), the mean estimate of
technically recoverable oil on the federally owned land in the Refuge is 7.7 billion
barrels (billion bbl), and there is a small chance that over 11.8 billion bbl could be
recovered on the federal lands. The mean estimate of economically recoverable oil
(at $55/bbl in 2003 dollars)1 on the federal lands is 7.14 billion bbl and there is a small
chance that the federal lands could have over 10.7 billion bbl of economically
recoverable oil. That amount would be nearly as much as the single giant field at
Prudhoe Bay, found in 1967 on the state-owned portion of the coastal plain west of
ANWR, now estimated to have held almost 14 billion bbl of economically recoverable
oil.
Moreover, if Congress opens federal lands in ANWR to development, current
law would also open Native lands. In addition, nearby onshore development would
also make state lands (already legally open to development) along the coast more
economically attractive, and as a result, these state lands might also become more
attractive to industry. While only the federal lands would produce income from bonus
bids, rents, and royalties, USGS figures show that when state and Native lands are
considered, the mean estimate of economically recoverable oil rises to 9.7 billion bbl,
and there is a small chance that economically recoverable oil in the three ownerships
might total over 14.6 billion bbl. (See “Oil,” below, for further discussion.)

CRS-2
The Refuge, especially the nearly undisturbed coastal plain, also is home to a
wide variety of plants and animals. The presence of caribou, threatened polar bears,
grizzly bears, wolves, migratory birds, and other species in this wild area has led some
to call the area “America’s Serengeti.” Some advocates have proposed that the
Refuge and two neighboring parks in Canada become an international park, and
several species found in the area (including polar bears, caribou, migratory birds, and
whales) are protected by international treaties or agreements. The analysis below
covers, first, the economic and geological factors that have triggered interest in
development, then the philosophical, biological, and environmental quality factors that
have generated opposition to it.
The conflict between high oil potential and nearly pristine nature in the Refuge
creates a dilemma: should Congress open the area for energy development or should
the area’s ecosystem continue to be protected from development, perhaps
permanently? What factors should determine whether, or when, to open the area? If
the area is opened, to what extent can damages be avoided, minimized, or mitigated?
To what extent should Congress legislate special management to guide the manner of
any development, and to what extent should federal agencies be allowed to manage
the area under existing law?

National Wildlife Refuge: Background and Issues, coordinated by M. Lynne Corn
(hereafter cited as CRS Report RL31278). For legal background, see CRS Report

Legislative History of the Refuge
The energy and biological resources of northern Alaska have been controversial
for decades, from legislation in the 1970s, to a 1989 oil spill, to more recent efforts
to use ANWR resources to address energy needs or to help balance the federal budget.
In November 1957, an application was filed to withdraw lands in northeastern Alaska
to create an “Arctic National Wildlife Range.” On December 6, 1960, after statehood,
the Secretary of the Interior issued Public Land Order 2214, reserving the area as the
Arctic National Wildlife Range. The potential for oil and gas leasing was expressly
preserved at that time.
In 1971, Congress enacted the Alaska Native Claims Settlement Act (ANCSA,
P.L. 92-203) to resolve all Native aboriginal land claims against the United States.
ANCSA provided for monetary payments and created village corporations that
received the surface estate to roughly 22 million acres of lands in Alaska, including
some in the National Wildlife Refuge System. Under §22(g) of ANCSA, these lands
in refuges were to remain subject to the laws and regulations governing use and

CRS-3
development of the particular refuge. Kaktovik Inupiat Corporation (KIC, the Native
village corporation in the ANWR area) received rights to three townships in the
geographic coastal plain of ANWR (and a fourth was added later). ANCSA also
created regional corporations that could select subsurface rights to some lands and full
title to others. Subsurface rights in refuges were not available.
The Alaska National Interest Lands Conservation Act of 1980 (ANILCA, P.L.
96-487) renamed the range as the Arctic National Wildlife Refuge, and expanded the
Refuge, mostly south and west, to include another 9.2 million acres. Section 702(3)
designated much of the original Refuge as a wilderness area, but not the coastal plain,
nor the newer portions of the Refuge. Instead, Congress postponed decisions on the
development or further protection of the coastal plain. Section 1002 directed a study
of ANWR’s “coastal plain” (therefore often referred to as the 1002 area) and its
resources. The resulting 1987 report (by FWS, USGS, and the Bureau of Land
Management (BLM)) was called the 1002 report or the Final Legislative
Environmental Impact Statement (FLEIS). ANILCA defined the “coastal plain” as
the lands specified on an August 1980 map — language that was later administratively
interpreted as excluding many Native lands, even though these lands are
geographically part of the coastal plain.2
Section 1003 of ANILCA prohibited oil and gas development in the entire
Refuge, or “leasing or other development leading to production of oil and gas from
the range” unless authorized by an act of Congress.3 (For more history of legislation
on ANWR and related developments, see CRS Report RL31278; for legal issues, see
CRS Report RL31115. For specific actions, including key votes, see CRS Report
RL32838, Arctic National Wildlife Refuge: Legislative Actions Through the 109th
Congress, First Session
, by Anne Gillis, M. Lynne Corn, Bernard A. Gelb, and
Pamela Baldwin.)
Actions in the 109th Congress. The ANWR debate took two basic routes
in the 109th Congress: (a) reconciliation bills (S. 1932 and H.R. 4241) under the
budget process, which cannot be filibustered; and (b) other bills (H.R. 6, an energy
bill; H.R. 2863, Defense appropriations; and H.R. 5429, a bill to open the Refuge to
development), which can be.4 These bills all provided for an expedited opening of
the Refuge to development to address national energy needs. For details of these bills,
and of House and Senate actions on them, see CRS Report RL33523, Arctic National
Wildlife Refuge (ANWR): Controversies for the 109th Congress
. In the end, Congress
did not send any of these bills to the President.

Actions in the 110th Congress. As in the 109th Congress, there was an effort
in the second session to assume ANWR revenues in the budget resolution (S.Con.Res.
70), through a motion to adjust budget levels to assume increased revenues from
opening ANWR to leasing and exploration. However, on May 14, 2008, the House
rejected the motion (185-229, Roll Call #321). In the Senate, during debate on S.
2284 (a bill originally concerning flood insurance) on May 13, 2008, the Senate
rejected the McConnell amendment (S.Amdt. 4720) to open ANWR to energy
development (42-56, Roll Call #123). In addition, rising gasoline prices during 2008
intensified interest in opening ANWR to development, and a number of bills to open
the coastal plain to development have been introduced during the second session.
The Energy Resource
The developed parts of Alaska’s North Slope suggest promise for ANWR’s
energy prospects. Oil-bearing strata extend eastward from structures in the National
Petroleum Reserve-Alaska through the Prudhoe Bay field, and may continue into and
through ANWR’s 1002 area. Both the recent oil price increases and changing costs
affect oil prospects.
The Current Market. Higher oil prices may increase interest in oil
development in ANWR and increase the hope of higher oil production, particularly
since higher prices might support more expensive oil recovery techniques. In
addition, the smaller fields thought to be present in the 1002 area might be more
attractive in a booming oil market, particularly if they are near any larger, more
promising fields that would be developed first. According the Energy Information
Administration (EIA), “the main impact of such approaches on the amount of oil
actually recovered from ANWR is likely to occur after 2030, the current time horizon
for EIA analyses.”5 In addition, drilling costs have increased in recent years,
particularly in northern Alaska, where costs increased 564% between 2000 and 2005
to $1,880 per foot drilled, compared to a 165% increase to $294 per foot in the lower
48 states.6 EIA further states:
The basic intuition that higher crude oil prices would likely result in higher
ultimate recovery from whatever resource exists in place is sound. However,
given the timing and cost considerations outlined above, EIA does not expect the
recent increase in oil prices to affect the projected profile of ANWR development
and production activities prior to 2030.... Therefore, this current analysis of
projected production from ANWR through 2030 parallels our prior recent
analyses ... that have used similar or identical information on ANWR resources
notwithstanding the recent run-up in world crude oil prices.7

CRS-5
Oil. Estimates of ANWR’s oil potential, both old and new, are based on limited
data and numerous assumptions about geology and economics. Recent interest has
centered especially on parts of the 1002 area west and north of the Marsh Creek
anticline, roughly a third of the 1002 area. (See Figure 5 in CRS Report RL31278.)
The most recent government geologic study of oil and natural gas prospects in
ANWR, completed in 1998 by the USGS,8 found an excellent chance (95%) that at
least 11.6 billion bbl of oil are present on federal lands in the 1002 area. (For
comparison, annual U.S. oil consumption from all sources is about 7.6 billion bbl.)
But the amount that would be economically recoverable depends in part on the
price of oil, and crude oil prices have increased substantially in the last three years,
bringing about $130/bbl in the futures market in late June 2008. In its latest economic
assessment, USGS estimated that, at $55/bbl in 2003 dollars,9 there is a 95% chance
that 3.9 billion bbl or more could be economically recovered and a 5% chance of 10.7
billion bbl or more on the federal lands.10 These estimates reflect new field
development practices, and cost and price changes since USGS’s 1998 assessment.
Moreover, as noted earlier, about one-third more oil may be under adjacent state
waters and Native lands.11 The state waters adjacent to the 1002 area are far from any
support system or land-based development and any oil under them is not presently
economic. If onshore development were to occur, allowing leases in state waters to
benefit from onshore transportation systems (airstrips, haul roads, pipelines, etc.) and
supply bases (gravel mines, water treatment plants, staging areas, etc.), these areas
might become more attractive to industry. In addition, a lifting of the statutory
prohibition on oil and gas development in the Refuge would not only lift the ban on
Native lands but might make smaller fields on Native lands more attractive, if they
were able to share facilities with nearby development, or if they became preferred
locations for support facilities, due to fewer restrictions on surface development.12
EIA estimated that if development began in 2008, production would begin in
about 2018, and grow to a peak in about 2028.13 The peak would range from about
510,000 bbl/day to 1,450,000 bbl/day, depending on the size of the resource.14 If so,
in 2030 ANWR production would range from 0.4% to 1.2% of world oil consumption,

11 According to the same USGS report, if state and Native lands are included, there is a 95%
chance that 5.4 billion bbl or more could be economically recovered and a 5% chance that
14.6 billion bbl or more could be economically recovered at this price.

and would reduce the world price of low-sulfur crude by $0.41/barrel to $1.44/barrel
in 2026. (EIA further notes that these reductions could be neutralized by a
corresponding decrease in production among other oil producers.) ANWR production
at these levels would help to hold fuel imports steady at about 51% between 2018 and
2025, by causing a corresponding reduction in crude oil imports. It would also help
to spread the costs of operating the Trans Alaska Pipeline System (TAPS) over a
larger number of barrels. EIA reported that the operation of TAPS is considered
uneconomic if flows fall below 200,000 bbl/day.
Natural Gas. Large quantities of natural gas are also estimated to be in the
1002 area. Being able to sell this gas probably would enhance development prospects
of the 1002 area and the rest of the North Slope — oil as well as gas. However, there
currently is no way to deliver the gas to market. Higher gas prices in the last few years
increased interest in the construction of a pipeline to transport natural gas from the
North Slope to North American markets — directly and/or via shipment in liquified
form in tankers. The 108th Congress acted to facilitate such a pipeline through loan
guarantees (P.L. 108-324). (See CRS Report RL33716, Alaska Natural Gas
Pipelines: Interaction of the Natural Gas and Steel Markets
, by Steven Cooney and
Robert Pirog, for more information.)
Advanced Technologies. As North Slope development proceeded after the
initial discovery at Prudhoe Bay, oil field operators developed less environmentally
intrusive ways to develop arctic oil, primarily through innovations in technology.
New drilling bits and fluids and advanced forms of drilling — such as extended reach,
horizontal, and “designer” wells — permit drilling to reach laterally far beyond a drill
platform, with the current record being 7 miles at one site in China. (See CRS Report
RL31022, Arctic Petroleum Technology Developments, by Bernard A. Gelb, M. Lynne
Corn, and Terry R. Twyman, for more information.)
Reducing the footprints of development has been a major goal of development.
Improved ice-based transportation infrastructure can serve remote areas during the
exploratory drilling phase on insulated ice pads. However, for safety reasons, use of
ice roads and pads may be limited in the more hilly terrain of the 1002 area: on a
slope, gravel structures provide greater traction than ice structures, and have been
permitted for exploration on state lands south of Prudhoe Bay. In addition to ice
technology, industry has been experimenting with essentially modified offshore
platforms mounted on supporting legs to hold exploration rigs above the tundra.
These rigs may offer access for exploration in areas lacking sufficient water or too
hilly to permit ice technology.
At the same time, warming trends in arctic latitudes have already shortened
winter access across the tundra by over 50% over the last 30 years and led to changes
in the standards for use of ice roads. If these trends continue, heavy reliance on ice
technology could be infeasible and might force greater reliance on gravel structures,
with inherently longer-lasting impacts. Rigid adherence to ice technology (instead of
gravel construction) might put some marginal fields out of reach due to the high cost
of exploration, development, or operation. Moreover, fields that begin with few roads
may expand their gravel road network as the field expands.

CRS-7
Because it is held as a model of modern development, the history of the Alpine
field, located along the border of the National Petroleum Reserve-Alaska (NPRA)
west of Prudhoe Bay, is relevant. Run by ConocoPhillips, it was considered
innovative because of the short road connecting the two initial pads, and the lack of
a road connection with the remainder of North Slope development, except in winter
via ice road. However, with the approval of five additional pads, the expansion of the
field will add roughly 27.5 miles of gravel roads to the existing 3 miles of roads, and
create 1,845 acres of disturbed soils, including 316 acres of gravel mines or gravel
structures.15 Approximately 150 miles of roads would be constructed if the field is
fully developed. If ANWR development follows a similar pattern, it is unclear
whether energy development could be held to a stringent limit on road or other gravel
construction and still allow producers to have access to otherwise economic fields.
Proponents of opening ANWR note that these technologies would mitigate the
environmental impact of petroleum operations, but not eliminate it. Opponents
maintain that facilities of any size would still be industrial sites and would change the
character of the coastal plain, in part because the sites would be spread out in the 1002
area and connected by pipelines and (probably) roads.
The Biological Resources
The FLEIS rated the Refuge’s biological resources highly: “The Arctic Refuge
is the only conservation system unit that protects, in an undisturbed condition, a
complete spectrum of the arctic ecosystems in North America” (p. 46). It also said:
“The 1002 area is the most biologically productive part of the Arctic Refuge for
wildlife and is the center of wildlife activity” (p. 46). The biological value of the 1002
area rests on intense productivity in the short arctic summer; many species arrive or
awake from dormancy to take advantage of this richness, and leave or become
dormant during the remainder of the year. Caribou have long been the center of the
debate over the biological impacts of Refuge development, but other species have also
been at issue. Among the other species most frequently mentioned are polar bears,
musk oxen, and the 135 species of migratory birds that breed or feed there. (For more
information on biological resources of the 1002 area, see CRS Report RL31278.)
An updated assessment of the array of biological resources in the coastal plain
was published in 2002 by the Biological Research Division of USGS.16 The report
analyzed new information about caribou, musk oxen, snow geese and other species
in the Arctic Refuge, and concluded that development impacts would be significant.

of USGS clarified that if development were restricted to the western portion of the
refuge (an option that was being considered by the Administration), the Porcupine
Caribou Herd (PCH) would not be affected during the early calving period, since the
herd is not normally found in the area at that time. Any impacts that might occur
when the herd subsequently moves into the area were not discussed in the memo.
A March 2003 report by the National Academy of Sciences (NAS) highlighted
impacts of existing development at Prudhoe Bay on arctic ecosystems.18 Among the
harmful environmental impacts noted were changes in the migration of bowhead
whales, in distribution and reproduction of caribou, and in populations of predators
and scavengers that prey on birds. NAS noted beneficial economic and social effects
of oil development in northern Alaska and credited industry for its strides in
decreasing or mitigating environmental impacts. It also said that some social and
economic impacts have not been beneficial. The NAS report specifically avoided
determining whether any beneficial effects were outweighed by harmful effects.
FWS recently listed polar bears as threatened under the Endangered Species
Act.19 (See CRS Report RL33941, by Eugene H. Buck, M. Lynne Corn, and Kristina
Alexander.) Among the information considered in listing the species was the effect
of accelerated polar climate change on polar bears and their prey (primarily seals),
threats to denning habitat, and effects of oil and gas development. The listing of polar
bears could have a significant impact on energy development in ANWR, since the
FLEIS stressed the unusual importance of the 1002 area as a location for dens of
pregnant female polar bears.
In a larger context, many opponents of development see the central issue as
whether the area should be maintained as an intact ecosystem — off limits to
development — not whether development can be accomplished in an environmentally
sound manner. In terms that emphasize deeply held values, supporters of wilderness
designation argue that few places as untrammeled as the 1002 area remain on the
planet, and fewer still on the same expansive scale. Any but the most transitory
intrusions (e.g., visits for recreation, hunting, fishing, subsistence use, research)
would, in their view, damage the integrity and the “sense of wonder” they see in the
area. The mere knowledge that a pristine place exists, regardless of whether one ever
visits it, can be important to those who view the debate in this light.
Major Legislative Issues in the 110th Congress
Some of the issues that have been raised most frequently in the current ANWR
debate are described briefly below. In addition to the issue of whether development
should be permitted at all, key aspects of the current debate include restrictions that

might be specified in legislation, including the physical size — or footprints — of
development; the regulation of activities on Native lands; the disposition of revenues;
labor issues; oil export restrictions; compliance with the National Environmental
Policy Act; and other matters. (References below to the “Secretary” refer to the
Secretary of the Interior, unless stated otherwise.) The analysis below describes issues
that have been raised repeatedly in past legislation.
Environmental Direction. If Congress authorizes development, it could
address environmental matters in several ways. Congress could impose a higher
standard of environmental protection because the 1002 area is in a national wildlife
refuge or because of the fragility of the arctic environment, or it could legislate a
lower standard to facilitate development. The choice of administering agency and the
degree of discretion given to it could also affect the approaches to environmental
protection. For example, Congress could make either FWS or BLM the lead agency
(with many observers assuming that FWS management would give more support to
protecting wildlife values). It could include provisions requiring use of “the best
available technology” or “the best commercially available technology” or some other
general standard. Congress could also limit judicial review of some or all of a
development program, including standards and implementation. Or, Congress could
leave much of the environmental direction to the Secretary.
The Size of Footprints. Newer technologies permit greater consolidation of
leasing operations, which tends to reduce the size and the environmental impacts of
development. One aspect of the debate in Congress has focused on the size of the
footprints in the development and production phases of energy leasing. The term
footprint does not have a universally accepted definition, and therefore the types of
structures falling under a “footprint restriction” are arguable (e.g., the inclusion of
exploratory structures, roads, gravel mines, port facilities, etc.).20 In addition, it is
unclear whether exploratory structures, or structures on Native lands, would be
included under any provision limiting footprints.21 The map accompanying S. 1932
in the 109th Congress (and subsequently cited in various other bills in the 110th
Congress) includes the Native lands in its definition of the Coastal Plain leasing area,
but how the federal leasing program will apply to those lands is not clear. See “New
Maps,” below.
Development advocates have emphasized a limit on the acreage of surface
disturbance, while opponents have emphasized the dispersal of not only the structures
themselves but also their impacts over much of the 1.5 million acres of the 1002 area.
One single consolidated facility of 2,000 acres (3.1 square miles) would not permit
full development of the 1002 area. Instead, full development of the 1002 area would
require that facilities, even if limited to 2,000 acres in total surface area, be widely
dispersed. Dispersal is necessary due to the limits of lateral (or extended reach)
drilling: the current North Slope record for this technology is 4 miles. If that record

Lynne Corn, for more information.

CRS-10
were matched on all sides of a single pad, at most about 4% of the Coastal Plain could
be developed from the single pad. Even if the current world record (7 miles) were
matched, only about 11% of the 1002 area could be accessed from a single compact
2,000-acre facility. In addition, drilling opponents argue that energy facilities have
impacts on recreation, subsistence, vegetation, and wildlife well beyond areas actually
covered by development.
Native Lands. Generally, the Alaska Natives (Inuit) along the North Slope
have supported ANWR development, while the Natives of interior Alaska (Gwich’in)
have opposed it, though neither group is unanimous. ANCSA resolved aboriginal
claims against the United States by (among other things) creating Village
Corporations that could select surface lands and Regional Corporations that could
select surface and subsurface rights as well. Kaktovik Inupiat Corporation (KIC)
selected surface lands (originally approximately three townships) on the coastal plain
of ANWR, but these KIC lands were administratively excluded from being considered
as within the administratively defined “1002 Coastal Plain.” A fourth township was
added by ANILCA, and is within the defined Coastal Plain. The four townships,
totaling approximately 92,000 acres, are all within the Refuge and subject to its
regulations. The Arctic Slope Regional Corporation (ASRC) obtained subsurface
rights beneath the KIC lands pursuant to a 1983 land exchange agreement. In
addition, there are currently thousands of acres of conveyed or claimed individual
Native allotments in the 1002 area that are not expressly subject to its regulations.
Were oil and gas development authorized for the federal lands in the Refuge,
development would then be allowed or become feasible on the nearly 100,000 acres
of Native lands, possibly free of any acreage limitation applying to development on
the federal lands, depending on how legislation is framed. The extent to which the
Native lands could be regulated to protect the environment is uncertain, given the
status of allotments and some of the language in the 1983 Agreement with ASRC.
None of the current bills specifically address development on the Native lands in
ANWR. (See also CRS Report RL31115, and “New Maps,” below.)
New Maps. During the 109th Congress, both the House and Senate created new
maps of the “Coastal Plain” that would be subject to leasing. (See CRS Report
RS22326, Legislative Maps of ANWR, by M. Lynne Corn and Pamela Baldwin,
hereafter cited as CRS Report RL22326.) The Coastal Plain was defined in §1002 of
ANILCA as the area indicated on an August 1980 map. An administrative articulation
of the boundary was authorized by §103(b) of ANILCA, and has the force of law. The
1980 map is now missing. Since the 1980 map is missing, evaluating whether the
administrative description properly excluded the Native lands is impossible, and, as
noted, the fourth Native township (selected later) is not excluded from the Coastal
Plain by that description. The legal description required under ANILCA was
completed in 1983 (48 Fed. Reg. 16858, Apr. 19, 1983; 50 C.F.R. Part 37, App. I), but
questions also surround this description. (See CRS Report RL31115.) The
description excluded three Native townships from the articulated Coastal Plain. Some
bills in various Congresses also have excluded these same Native lands by referring
to the 1980 map and the administrative description.
Revenue Disposition. Another issue is whether Congress may validly
provide for a disposition of revenues other than the (essentially) 90% state - 10%
federal split mentioned in the Alaska Statehood Act. A court in Alaska v. United

CRS-11
States (35 Fed. Cl. 685, 701 (1996)) indicated that the language in the Statehood Act
means that Alaska is to be treated like other states for federal leasing conducted under
the Mineral Leasing Act
(MLA), which contains (basically) a 90%- 10% split.
Arguably, Congress can establish a different, non-MLA leasing regimen — for
example, the separate leasing arrangements that govern the National Petroleum
Reserve-Alaska, where the revenue sharing formula is 50/50 — but this issue was not
before the court and hence remains an open issue. (For more on this issue, see CRS
Report RL31115.)
Project Labor Agreements (PLAs). A recurring issue in federal and
federally funded projects is whether project owners or contractors should be required,
by agreement, to use union workers. PLAs establish the terms and conditions of work
that would apply for the particular project, and may also specify a source to supply the
craft workers. Proponents of PLAs, including construction and other unions, argue
that PLAs ensure a reliable, efficient labor source, help keep costs down, and ensure
access for union members to federal and federally funded projects. Opponents,
including nonunion firms and their supporters, believe that PLAs inflate costs, reduce
competition, and unfairly restrict access to those projects. There is little independent
information to weigh the validity of the conflicting assertions.
Oil Export Restrictions. Export of North Slope oil in general, and any
ANWR oil in particular, has been an issue, beginning at least with the authorization
of TAPS and continuing into the current ANWR debate. The Trans Alaska Pipeline
Authorization Act (P.L. 93-153, 43 U.S.C.§§1651 et seq.) specified that oil shipped
through it could be exported internationally, but only under restrictive conditions.
When California prices fell in the mid-1990s, causing complaints from both North
Slope and California producers, Congress amended the MLA to provide that oil
transported through the pipeline may be exported unless the President finds, after
considering stated criteria, that exports are not in the national interest (P.L. 104-58,
30 U.S.C. §185(s)). North Slope exports rose to a peak of 74,000 bbl/day in 1999, or
7% of North Slope production. These exports ceased voluntarily in May 2000, and
have since been minimal to none, due to high demand domestically. If Congress
wished to limit export of oil from the 1002 area by applying the restriction to oil
transported through TAPS, the restriction might not be effective: oil shipment via
tanker could become practical if current warming trends in the Arctic continue and if
crude oil prices provide sufficient incentive.
NEPA Compliance. The National Environmental Policy Act of 1969 (NEPA,
P.L. 91-190; 43 U.S.C. §§4321-4347) requires the preparation of an environmental
impact statement (EIS) to examine major federal actions with significant effects on
the environment, and to provide public involvement in agency decisions. The last full
EIS examining the effects of leasing development in ANWR was completed in 1987,
and some observers assert that a new EIS is needed to support development now.
NEPA requires an EIS to analyze an array of alternatives, including a “no action”
alternative. Some development supporters would like to see the process truncated, in
light of past analyses and to hasten production. Development opponents, and NEPA
supporters, argue that the 21-year gap and changed circumstances since the last
analysis necessitates a thorough update, and stress the flaws they found in the 1987
FLEIS.

CRS-12
Compatibility with Refuge Purposes. Under current law for the
management of national wildlife refuges (16 U.S.C.§668dd), and under 43 C.F.R.
§3101.5-3 for Alaskan refuges specifically, an activity may be allowed in a refuge
only if it is compatible with the purposes of the particular Refuge and with those of
the Refuge System as a whole. Many past bills have addressed this issue by stating
that the energy leasing program and activities in the coastal plain are deemed to be
compatible with the purposes for which ANWR was established and that no further
findings or decisions are required to implement this determination. This language
appears to eliminate the usual compatibility determination processes. The extent of
leasing “activities” that might be included as compatible is debatable and arguably
might encompass necessary support activities, such as construction and operation of
port facilities, staging areas, and personnel centers.
Judicial Review. Leasing proponents urge that any ANWR leasing program
be put in place promptly and argue that expediting, curtailing, or prohibiting judicial
review is desirable to achieve that goal. Judicial review can be expedited through
procedural changes such as reducing the time limits within which suits must be filed,
avoiding some level(s) of review, curtailing the scope of the review, or increasing the
burden imposed on challengers.
Special Areas. Some have supported setting aside certain areas in the Coastal
Plain for protection of their ecological or cultural values. This could be done by
designating the areas specifically in legislation, or by authorizing the Secretary to set
aside areas to be selected after enactment. The FLEIS identified four special areas that
together total more than 52,000 acres. The Secretary could be required to restrict or
prevent development in these areas or any others that may seem significant, or to
select among areas if an acreage limitation on such set-asides is imposed.
Non-Development Options. Several options are available to Congress that
would either postpone or forbid development, unless Congress were to change the
law. These options include allowing exploration only, designating the 1002 area as
wilderness, and taking no action. Some have argued that the 1002 area should be
opened to exploration first, before a decision is made on whether to proceed to
leasing. Those with this view hold that greater certainty about any energy resources
in the area would lead to a better decision about opening some or all of the 1002 area
for leasing. This idea has had little support over the years because various interests
see insufficient gain from such a proposal. (CRS Report RL31278 discusses the pros
and cons of this approach.)
Another option is wilderness designation. Energy development is not permitted
in wilderness areas, unless there are pre-existing rights or unless Congress specifically
allows it or reverses the designation. Wilderness designation would tend to preserve
existing recreational opportunities and related jobs, as well as the existing level of
protection of subsistence resources, including the Porcupine Caribou Herd. H.R. 39
would designate the 1002 area as part of the National Wilderness System.
Under ANILCA and the 1983 Agreement, development of the surface and
subsurface holdings of Native corporations in the Refuge is precluded as long as oil
and gas development is not allowed on the federal lands in the Refuge. Because
current law prohibits development unless Congress acts, the no action option also

CRS-13
prevents energy development on both federal and Native lands. Those supporting
delay often argue that not enough is known about either the probability of discoveries
or about the environmental impact if development is permitted. Others argue that oil
deposits should be saved for an unspecified “right time.”
