MOST RECENT DEVELOPMENTS
The Senate passed the FY2007 budget resolution (S.Con.Res. 83; yeas 51, nays 49, Roll
Call #74; no written report) on March 16, 2006. Its sole reconciliation instruction (§201)
directed the Committee on Energy and Natural Resources to reduce budget authority by an
amount equal to predicted revenues from ANWR development. The move, if retained in the
final resolution, would facilitate inclusion of ANWR development in a reconciliation bill;
reconciliation bills are not subject to Senate filibusters. The House budget resolution, as
reported (H.Con.Res. 376, H.Rept. 109-402), did not have ANWR language, nor direction
for the House Resources Committee. Recent increases in gasoline pump prices have added
to calls for ANWR 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 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 is 7.7 billion barrels (billion bbl), and there is a small
chance that, taken together, the fields on this federal land could hold 10.7 billion bbl of
economically recoverable oil (at $55/bbl in 2003 dollars). 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. (See “Oil,” below, for further discussion.)
The Refuge, especially the nearly undisturbed coastal plain, also is home to a wide
variety of plants and animals. The presence of caribou, polar bears, grizzly bears, wolves,
migratory birds, and other species in this wild area has led some to call the area “America’s
Serengeti.” The Refuge and two neighboring parks in Canada have been proposed for 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 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 of the area if it is developed, and to what extent should federal agencies
be allowed to manage the area under existing law?

Wildlife Refuge: Background and Issues, by M. Lynne Corn (coordinator) (hereafter cited as

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 for the withdrawal of lands in northeastern Alaska to create
an “Arctic National Wildlife Range” was filed. 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.
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 development of the particular Refuge. Kaktovik Inupiat
Corporation (KIC, the local corporation) received rights to three townships in the coastal
plain of ANWR (and a fourth was added later). ANCSA also created Regional Corporations
which 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,
94 Stat. 2371) 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 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.
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. (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

Actions in the 109th Congress, First Session. As explained below, the ANWR
debate has taken 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 and H.R. 2863, an energy bill and Defense appropriations, respectively) which can be.1
(See Omnibus Energy Legislation, below.) The FY2006 Senate budget resolution
(S.Con.Res. 18) passed by the Senate Budget Committee included instructions to the Senate
Committee on Energy and Natural Resources to “report changes in laws within its
jurisdiction sufficient to reduce outlays by $33,000,000 in FY2006, and $2,658,000,000 for
the period of fiscal years 2006 through 2010.” This resolution assumed that the committee
would report legislation to open ANWR to development, and that leasing would generate
$2.5 billion in revenues for the federal government over five years. An amendment (S.Amdt.
168) on March 16 to remove these instructions was defeated (yeas 49, nays 51, Roll Call
#52). The House FY2006 budget resolution (H.Con.Res. 95, H.Rept. 109-17), while
instructing the House Resources Committee to provide somewhat smaller reductions in
outlays, did not include assumptions about ANWR revenues.
The conference agreement (H.Con.Res. 95, H.Rept. 109-62) approved by the House and
Senate on April 28, 2005, contained reductions in spending targets of $2.4 billion over
FY2006 to FY2010 for the House Resources and Senate Energy Committees that would be
difficult to achieve unless ANWR development legislation were passed. The inclusion of
the Senate target particularly set the stage for including ANWR development legislation in
a reconciliation bill, since reconciliation bills cannot be filibustered (i.e., they require only
a simple majority, rather than 60 votes to invoke cloture).
Under the Congressional Budget Act of 1974 (CBA, Titles I-IX of P.L. 93-344, as
amended, 2 U.S.C. §§601-688), while the target reductions of the budget resolutions are
binding on the committees, the associated assumptions are not. The Senate Energy and
Natural Resources Committee did choose to meet its target by recommending ANWR
legislation, and the Budget Committee incorporated the recommendation as Title IV of S.
1932, the Deficit Reduction Act of 2005.2 The House Resources Committee included
ANWR legislation, and other spending reductions and offsetting collections, thereby more
than meeting the Committee’s targets. These measures were incorporated by the House
Budget Committee into an omnibus reconciliation bill. However, before the House bill came
to the floor, considerable opposition to the ANWR provision developed among a number
of Republicans, 24 of whom signed a letter to the Speaker opposing its inclusion. The
provision was removed before floor consideration; S. 1932 (with the text of H.R. 4241
inserted in lieu — minus an ANWR provision) passed the House on November 18, 2005
(yeas 217, Nays 215; Roll call #601). ANWR was a major issue in conference. In the end,
the conference report (H.Rept. 109-362) omitted ANWR development, and the President
signed the measure on February 8, 2006 (P.L. 109-171).

ANWR in the Defense Appropriations Bill. As Congress moved toward the
December recess, and the chance of an agreement on reconciliation with an ANWR provision
seemed to fade, Senator Stevens (Chair of the Defense Appropriations Subcommittee) added
an ANWR development title to the “must-pass” FY2006 Defense appropriations bill (H.R.
2863) in conference. Senators opposing ANWR were forced to choose between filibuster
of the popular measure or acquiescing to opening the Refuge. Members began a filibuster,
and a cloture motion failed (yeas 56, nays 44, Roll Call #364). While the conference report
was approved, the relevant two Divisions (C and D) were removed through House and
Senate passage of S.Con.Res. 74, correcting the enrollment of the bill (P.L. 109-148).
Omnibus Energy Legislation. The House Resources Committee considered and
marked up its portion of the omnibus energy bill on April 13, 2005, before the bill was
introduced. The provisions approved by the committee were then incorporated into the
House version of H.R. 6, introduced on April 18. The House passed H.R. 6 on April 21
(yeas 249, nays 183, Roll Call #132). The Senate passed its version of H.R. 6 on June 28,
2005 (yeas 85, nays 12, Roll Call #158). The Senate version contained no ANWR
development provisions. The ANWR title was omitted in the final measure (P.L. 109-58).
Actions in the 109th Congress, Second Session. The Senate passed the
FY2007 budget resolution (S.Con.Res. 83; yeas 51, nays 49, Roll Call #74; no written report)
on March 16, 2006. Its sole reconciliation instruction (§201) directs the Committee on
Energy and Natural Resources to reduce budget authority by an amount equal to predicted
bonus bids, royalties, and rental revenues from ANWR development. According to press
reports, Senators hoped that such a reconciliation bill, perhaps with ANWR as its sole
subject, might lead to sufficient bipartisan support in the House to counterbalance opposition
of the 24 Republican Members who opposed its inclusion in a larger reconciliation measure
in the first session. The House Budget Committee did not include such an instruction in its
budget resolution (H.Con.Res. 376, H.Rept. 109-402) on March 29, 2006, and to date the
House has not passed a budget resolution.
The Energy Resource
The developed parts of Alaska’s North Slope suggest promise for ANWR’s 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.
Oil. Estimates of ANWR oil potential, both old and new, depend upon 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, an area which
comprises 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,3 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 7.5 billion bbl.)

But the amount that would be economically recoverable depends on the price of oil, and
crude oil prices have increased substantially in the last two years, bringing roughly $70 per
barrel in the futures market in mid-May 2006. In its latest assessment, USGS estimated that,
at $55/bbl in 2003 dollars, 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.4 These estimates
reflect field development practices introduced and cost and price changes since USGS’s 1998
assessment. Roughly one-third more oil may be under adjacent state waters and Native lands
— areas that could be difficult to develop economically without access through federal land
or a lifting of the statutory prohibition on oil and gas development in the Refuge.
The U.S. Energy Information Administration estimated that, at a relatively fast
development rate, production would peak 15-20 years after the start of development, with
maximum daily production rates of roughly 0.015% of the resource. Production at the slower
rate would peak about 25 years after the start of development, at a daily rate equal to about
0.0105% of the resource. Peak production associated with a technically recoverable resource
of 5.0 billion bbl at the faster development rate would be 750,000 bbl per day, roughly 4%
of current U.S. petroleum consumption (about 20.5 million bbl per day). (For economic
impacts of development, see CRS Report RS21030, ANWR Development: Economic
Impacts
, by Bernard A. Gelb.)
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 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 (P.L. 108-324).
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 seven 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; gravel structures
could be required for greater safety. 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 and led to
changes in the standards for use of ice roads; if these trends continue, heavy reliance on ice
technology could be infeasible. 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. Accelerated warming in polar areas is also making ice
technology problematic and might force greater reliance on gravel structures. Moreover,
fields that begin with few roads may expand their gravel road network as the field expands.
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 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.5 Approximately 150 miles of roads would be constructed
if the field were 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.
A March 2003 report by the National Academy of Sciences (NAS) highlighted impacts
of existing development at Prudhoe Bay on arctic ecosystems. 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.
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 the 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.6 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. A follow-up memo7 on
caribou by one of the authors to the Director 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 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.
FWS has recently begun a review to determine whether polar bears should be listed as
threatened under the Endangered Species Act (71 Fed. Reg. 6745, Feb. 9, 2006). Among the
information to be considered are the effects 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
magnificent 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 109th 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 the ANWR title (the “House bill”) of the reconciliation
recommendations as submitted by the House Committee on Resources (and later dropped
before floor consideration), the provisions of Division C of the conference report on H.R.
2863 (the “Defense bill”), and §4001 of S. 1932, the Senate reconciliation bill (the “Senate
bill”). Because of the lack of detail in §4001, many aspects of ANWR leasing would be left
to administrative decisions, with levels of public participation in some instances curtailed
along with judicial review, as noted below.
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. 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.
The House bill as reported would have named BLM as the lead agency. Section 6107(a)
would require the Secretary to administer the leasing program so as to “result in no
significant adverse effect on fish and wildlife, their habitat, and the environment, [and to
require] the application of the best commercially available technology....” Section 6103(a)(2)
would also have required that this program be done “in a manner that ensures the receipt of
fair market value by the public for the mineral resources to be leased.” It is unclear how the
two goals of environmental protection and fair market value are to relate to each other (e.g.,
if environmental restrictions might make some fields uneconomic). Subsections 6106(a)(3)
and (5) would require lessees to be responsible and liable for reclamation of lands within the
Coastal Plain (unless the Secretary approves other arrangements), and the lands must support
pre-leasing uses or a higher use approved by the Secretary. There were requirements for
mitigation, development of regulations, and other measures to protect the environment.
These included prohibitions on public access to service roads, and other transportation
restrictions. Other provisions might also affect environmental protection. (See “Judicial
Review,” below.) The Defense bill (§7) was similar to the House bill. The Senate bill
(§4001(b)(1)(B)) directed the Secretary to establish and implement an “environmentally
sound” leasing system, but did not provide further direction.
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.). (See CRS Report RL32108, North Slope Infrastructure and the ANWR
Debate
, by M. Lynne Corn.) In addition, it is unclear whether exploratory structures, or
structures on Native lands, would be included under any provision limiting footprints. (See
CRS Report RS22143, Oil and Gas Leasing in the Arctic National Wildlife Refuge (ANWR):

The 2,000-Acre Limit, by Pamela Baldwin and M. Lynne Corn, for a discussion of an acreage
limit.) The new map accompanying the Senate bill includes the Native lands in 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 were matched on all sides of a single pad, at most about 4% of the
Coastal Plain could be developed from that pad. Even if the current world record (seven
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.
The House bill as reported (§6107(d)(9)) would have provided for consolidation of
leasing operations to reduce environmental impacts of development. House §6107(a)(3)
further would have required, “consistent with the provisions of section 6103” (which include
ensuring receipt of fair market value for mineral resources), that the Secretary administer the
leasing program to “ensure that the maximum amount of surface acreage covered by
production and support facilities, including airstrips and any areas covered by gravel berms
or piers for the support of pipelines, does not exceed 2,000 acres on the Coastal Plain.” The
terms used were not defined in the bill and therefore the range of structures covered by the
restriction is arguable (e.g., whether roads, gravel mines, causeways, and water treatment
plants would be included under this provision). In addition, the wording may not apply to
structures built during the exploratory phase. An essentially identical provision (§4001(f))
is found in the Senate bill and the Defense bill (§7(a)(3)). The Defense bill also called for
facility consolidation (§7(d)(4)) and for the Secretary to develop a consolidation plan (§7(f)).
Native Lands. 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
CRS-9

IB10136

is uncertain, given the status of allotments and some of the language in the 1983 Agreement
with ASRC. None of the current bills address development on the Native lands in ANWR.
(See also CRS Report RL31115, and New Maps, below.)
New Maps. Both the House and Senate have created new maps of the “Coastal Plain”
that will be the subject of 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. This map is now missing. An administrative articulation of the boundary was
authorized by §103(b) of ANILCA, and has the force of law. This legal description was
completed in 1983 (48 Fed. Reg. 16838), 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. However, if
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) was not excluded from the Coastal Plain by that description.
The Senate Energy Committee bill (§4001(a)) provided a new map, dated September
2005, to accompany its submission to the Budget Committee for reconciliation. This map
includes all Native lands in the “Coastal Plain”(see Figure 1 in CRS Report RS22326).
However, the bill text remains unchanged and it is not clear what extent of federal control
of Native lands was intended or accomplished by the map change. For example, language
is retained that “notwithstanding any other provision of law” directs a 50/50 revenue split
between the state of Alaska and the federal government, thereby possibly giving rise to
Native claims for compensation for revenues from their lands. If this provision was not
intended to apply to Native lands, it is not clear whether other provisions also might not
apply. Also, some of the terms in the 1983 Agreement call for an express congressional
override to negate their effects, and the text of the bill does not discuss the Native lands. The
Defense bill also used a USGS map dated September 2005 (§2(4)); it is not clear whether the
map is the same as the one referred to in the Senate bill.
The House also adopted a new map, dated October 25, 2005. It appears to follow the
1983 administrative articulation of the Coastal Plain — it excludes the three Native
townships, but leaves the fourth within the Coastal Plain to which the leasing provisions
would arguably apply.
Revenue Disposition. Another issue is whether Congress may validly provide for
a disposition of revenues formula other than the 90% state - 10% federal split mentioned in
the Alaska Statehood Act. A court in Alaska v. United 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 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 in this case and hence remains an open issue.
Several sections of the House bill as reported related to revenues. Section 6109 would
have provided that 50% of adjusted revenues be paid to Alaska, and the balance be deposited
CRS-10

IB10136
05-16-06
in the U.S. Treasury as miscellaneous receipts, except for a portion to assist Alaska
communities in addressing local impacts of energy development. Under §6103(a), the
Secretary was to establish and implement a leasing program under the Mineral Leasing Act,
yet “notwithstanding any other provision of law,” §6112 directed a revenue sharing program
different from that in the MLA. Given the wording of the Alaska Statehood Act, establishing
a leasing program “under the MLA,” yet providing for a different revenue disposition, could
raise validity questions. If a court struck down the revenue-splitting provision, the court
would then have to determine if that provision was severable — whether Congress would
have enacted the rest of the statute without the flawed provision. If a court both struck down
the revenue-sharing provision and found it to be severable, then Alaska could receive 90%
of ANWR revenues. In a different subtitle, §6514 would create the Federal Energy Natural
Resources Enhancement Fund and apply a portion of moneys received under the revenues
section of the MLA to certain wildlife and habitat purposes. It is not clear whether moneys
from ANWR leasing would be eligible for this use, since leasing in ANWR, while under the
MLA, would have special revenue-splitting provisions.
The Senate bill does not expressly state that leasing would be under the MLA.
“Notwithstanding any other provision of law,” it directs receipts from leasing and operations
“authorized under this section” to be divided equally between the state of Alaska and the
federal government. This wording may avoid a conflict with the Alaska Statehood Act.
Because of the change in the Senate definition of “Coastal Plain” and the accompanying map,
the bill may include revenues from Native lands in the 50/50 split. The Defense bill
(Division D, §1) also provided for a 50/50 split, and the Division contained various
provisions for distribution of certain percentages of the federal share to various purposes,
including hurricane relief. In addition, §14 of Division C contained a severability provision
that provided explicitly that if any portion of either Division C or D were held to be
unconstitutional, the remainder of the two divisions would not be affected. It is not clear to
what provisions the severability language might apply. As discussed, there may be validity
issues regarding the revenue split, but those issues may rest on contractual interpretations,
rather than constitutional concerns. However, if ANWR development is a part of a revenue-
raising bill and the 50/50 revenue split were struck down, Alaska would receive 90% of the
ANWR revenues and fewer federal funds would be available for programs premised on the
50% federal share. In these circumstances, a court might address the severability issue aside
from the constitutional context.
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 will 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 sort out the conflicting assertions.
The House bill (§6106(b)) as reported would have directed the Secretary to require
lessees in the 1002 area to “negotiate to obtain a project labor agreement” — “recognizing
the Government’s proprietary interest in labor stability and the ability of construction labor
and management to meet the particular needs and conditions of projects to be developed....”
CRS-11

IB10136

The Defense bill (§6(b)) contained similar provisions, but the Senate bill had no similar
provision.
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 the Trans Alaska
Pipeline System (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, but only under restrictive conditions. When California prices
fell in the mid-1990s, causing complaints from California and North Slope 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. 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.
Recent proposed bans on export of ANWR oil have not been tied to shipment through
TAPS. The House bill as reported (§6106(a)(8)) would have prohibited any export of oil
produced in the 1002 area as a condition of a lease. The Senate bill (§4001(g) contained a
similar provision, as did the Defense bill (§12). However, inasmuch as other North Slope oil
is allowed to be exported, it would appear that prohibiting the export of ANWR oil could be
moot: producers aiming to tap the export market would substitute other North Slope oil to
meet the demand.
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 19-year gap and changed
circumstances since the last analysis necessitates a thorough update, and stress the flaws they
found in the 1987 FLEIS.
Section 6103(c) of the House bill as reported would have deemed the 1987 FLEIS to
satisfy NEPA requirements with respect to prelease activities and the development and
promulgation of leasing regulations, and requires the Secretary to prepare an EIS of all other
actions authorized by the subtitle before the first lease sale. Consideration of alternatives is
to be limited to two choices, a preferred leasing action and a “single leasing alternative.”
(Generally, an EIS must analyze several alternatives, including a “no action” alternative.)
Compliance with the subsection is deemed to satisfy all requirements to analyze the
environmental effects of proposed leasing. The Defense bill (Division C, §3(c)) was
essentially identical. S. 1932 (§4001(c)) had similar provisions, but did not expressly require
an EIS for leasing.
CRS-12

IB10136

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. Section
6103(c) of the House bill as reported, the Defense bill (§3(c)), and §4001(c) of S. 1932 state
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 of
review, curtailing the scope of the review, or increasing the burden imposed on challengers.
The House bill as reported (§6108) required that any complaints seeking judicial review be
filed within 90 days. Sections 6108(a)(1) and (a)(2) appeared to contradict each other as to
whether suits are to be filed in “any appropriate district court” or in the Court of Appeals in
Washington, DC. The Defense bill (§8(a)) specified the latter. The House bill (§6108(a)(3))
would also have limited the scope of review by stating that review of a secretarial decision,
including environmental analyses, would be limited to whether the Secretary complied with
the terms of the ANWR subtitle, that it would be based on the administrative record, and that
the Secretary’s analysis of environmental effects is “presumed to be correct unless shown
otherwise by clear and convincing evidence to the contrary.” This standard is unclear, but
in this context arguably would make overturning a decision more difficult. S. 1932 and the
Defense bill are similar, but required complaints to be filed only in the U.S. Court of Appeals
in Washington, DC (§4001(c) and §8(a) respectively). The Senate bill omitted the
presumption concerning the Secretary’s analysis of environmental effects.
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. The House bill as reported (§6103(e)) would have
allowed the Secretary to set aside up to 45,000 acres (and names one specific special area)
in which leases, if permitted, would forbid surface occupancy. As mentioned above, the
FLEIS identified four special areas that together total more than 52,000 acres, so the
Secretary would be required to select among these areas or any others that may seem
significant. Section 6103(f) also stated that the closure authority in the ANWR title is to be
the Secretary’s sole authority, which might limit possible secretarial actions under the
Endangered Species Act. The Defense bill (§3(e)) was essentially identical. The Senate bill
had no provision for special areas.
CRS-13

IB10136

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
with greater certainty about any energy resources in the area, a better decision could be made
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. 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 prevents energy development. 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.” H.R. 567 and S. 261 would designate the 1002 area as part of the
National Wilderness System.
