The concentration of production of rare earth elements (REEs)
outside the United States raises the important issue of supply
vulnerability. REEs are used for new energy technologies and
national security applications. Is the United States vulnerable to
supply disruptions of REEs? Are these elements essential to U.S.
national security and economic well-being? There are 17 rare earth
elements (REEs), 15 within the chemical group called lanthanides,
plus yttrium and scandium. The lanthanides consist of the
following: lanthanum, cerium, praseodymium, neodymium, promethium,
samarium, europium, gadolinium, terbium, dysprosium, holmium,
erbium, thulium, ytterbium, and lutetium. Rare earths are
moderately abundant in the earth's crust, some even more abundant
than copper, lead, gold, and platinum. While more abundant than
many other minerals, REEs are not concentrated enough to make them
easily exploitable economically. The United States was once
self-reliant in domestically produced REEs, but over the past 15
years has become 100% reliant on imports, primarily from China,
because of lower-cost operations.
In the past, the oil and gas industry considered gas locked in
tight, impermeable shale uneconomical to produce. However, advances
in directional well drilling and reservoir stimulation have
dramatically increased gas production from unconventional shales.
The United States Geological Survey estimates that 200 trillion
cubic feet of natural gas may be technically recoverable from these
shales. Recent high natural gas prices have also stimulated
interest in developing gas shales. Although natural gas prices fell
dramatically in 2009, there is an expectation that the demand for
natural gas will increase. Developing these shales comes with some
controversy, though. The hydraulic fracturing treatments used to
stimulate gas production from shale have stirred environmental
concerns over excessive water consumption, drinking water well
contamination, and surface water contamination from both drilling
activities and fracturing fluid disposal. The saline "flowback"
water pumped back to the surface after the fracturing process poses
a significant environmental management challenge in the Marcellus
region. The flowback's high content of total dissolved solids (TDS)
and other contaminants must be disposed of or adequately treated
before discharged to surface waters. The federal Clean Water Act
and state laws regulate the discharge of this flowback water and
other drilling wastewater to surface waters, while the Safe
Drinking Water Act (SDWA) regulates deep well injection of such
wastewater. Hydraulically fractured wells are also subject to
various state regulations. Historically, the EPA has not regulated
hydraulic fracturing, and the 2005 Energy Policy Act exempted
hydraulic fracturing from SDWA regulation. Recently introduced
bills would make hydraulic fracturing subject to regulation under
SDWA, while another bill would affirm the current regulatory
exemption. Gas shale development takes place on both private and
state-owned lands. Royalty rates paid to state and private
landowners for shale gas leases range from 121/2% to 20%. The four
states (New York, Pennsylvania, Texas, and West Virginia) discussed
in this report have shown significant increases in the amounts paid
as signing bonuses and increases in royalty rates. Although federal
lands also overlie gas shale resources, the leasing restrictions
and the low resource-potential may diminish development prospects
on some federal lands. The practice of severing mineral rights from
surface ownership is not unique to the gas shale development.
Mineral owners retain the right to access surface property to
develop their holdings. Some landowners, however, may not have
realized the intrusion that could result from mineral development
on their property. Although a gas-transmission pipeline-network is
in place to supply the northeast United States, gas producers would
need to construct an extensive network of gathering pipelines and
supporting infrastructure to move the gas from the well fields to
the transmission pipelines, as is the case for developing any new
well fiel
The U.S. Congress and the Administration are involved in a major
policy debate over oil and gas development from federal lands and
from federal mineral estate underlying certain privately owned
lands. Within the framework of U.S. public lands policy,
restrictions and withdrawals have affected the amount of land that
can be developed.
The General Mining Law of 1872 is one of the major statutes that
direct the federal government's land management policy. The law
grants free access to individuals and corporations to prospect for
minerals in public domain lands, and allows them, upon making a
discovery, to stake (or ]locate]) a claim on that deposit. A claim
gives the holder the right to develop the minerals and may be
]patented] to convey full title to the claimant. A continuing issue
is whether this law should be reformed, and if so, how to balance
mineral development with competing land uses. The right to enter
the public domain and freely prospect for and develop minerals is
the feature of the claim-patent system that draws the most vigorous
support from the mining industry. Critics consider the claim-patent
system a giveaway of publicly owned resources because of the small
amounts paid to maintain a claim and to obtain a patent. Congress
has imposed a moratorium on mining claim patents since FY1995.
Access to potential oil and gas resources under the U.S. Outer
Continental Shelf (OCS) continues to be controversial. Moratoria on
leasing and development in certain areas were established by
Congress (beginning in 1981) and by the President (beginning in
1990). These moratoria were largely eliminated in 2008 and 2009,
although a few areas remain legislatively off limits to leasing.
The 111th Congress may be unlikely to reinstate broad leasing
moratoria, but some members have expressed interest in protecting
areas (e.g., the Georges Bank or Northern California) or
establishing protective coastal buffers. Pressure to expand oil and
gas supplies and protect coastal environments and communities will
likely lead Congress and the Administration to consider carefully
which areas to keep open to leasing and which to protect from
development.
"She could see to the horizon to where the Brooklyn and Manhattan
bridges formed necklaces. So writes Susan Margulies Kalish in The
Cerebral Jukebox, her first collection of poetry. With an astute
eye for the telling detail, she evokes her childhood in Manhattan s
Lower East Side. Stuyvesant Town, a middle-class housing
development of a hundred look-alike buildings, became her mid-city
haven during the baby boom that followed World War II. Her favorite
jukebox hits of the Fifties filter through free verse vignettes,
recalling a time of innocence, while the songs of the Sixties echo
the turbulence of her coming of age in a time of great change. In
succeeding sections she celebrates family, travel, and historical
connection, bringing the book s jukebox journey full circle.
Complete with the author s illustrations that eloquently weave
together family and neighborhood photographs throughout, The
Cerebral Jukebox shares unforgettable recollections from one woman
s life as she matures from childhood to adulthood in the greatest
city in the world."
