When
Hurricane Katrina pummeled Gulf Coast communities in August, it left behind
a daily reminder of the disaster nationwide: gasoline prices above $3 a gallon.
In the weeks following the storm, gas prices rose, some stations ran dry, and
other stations reported gas lines the likes of which have not been seen since
the 1970s (see story, page 57). As residents of Louisiana
and Mississippi struggle to rebound, so too does the oil and gas industry.

The Gulf of Mexico accounts for 35 percent of U.S. domestic oil production and
20 percent of U.S. natural gas production, according to the U.S. Energy Information
Administration (EIA). Additionally, more than 10 percent of U.S. oil imports
run through the Gulf Coast, which is also home to many refineries and pipeline
networks. The area represents a complex that constitutes our single most
important energy asset, wrote Daniel Yergin, chairman of Cambridge Energy
Research Associates in The Wall Street Journal on Sept. 2, and the full
scope of the energy disaster will not be understood for some time.
The high gas prices immediately following the storm were tied to Katrinas
impact on the refineries and pipelines on the Gulf Coast. The storm completely
shut down 10 refineries and slowed services at six others across the region,
as well as knocking out power to the pipelines that transport petroleum to the
Midwest and East Coast. Although these pipelines were operating at full capacity
within a week, refineries have not fared as well.
Ten percent of the nations refining capacity was lost in the storm. Some
of the refining capacity came back quickly, but at press time, four refineries
remained closed due to severe damage and flooding, says John Felmy, an economist
with the American Petroleum Institute. Considering the inspectors cant
even get in to assess the damages, its really indeterminate how long theyll
be down.
The nation may also face several months before full production capacity can
be reached at the offshore oil platforms and rigs that were damaged in the storm,
Felmy says. According to the U.S. Minerals Management Service, close to 80 percent
of the 819 manned oil platforms in the Gulf of Mexico were evacuated and shut
down prior to the storm, and almost 70 percent of 134 active rigs were evacuated.
A week after the storm, 228 platforms and 37 rigs remained empty, representing
an average of 1 million barrels of oil a day of lost production.
At least 50 oil platforms or rigs were severely damaged or lost, Felmy says.
Energy companies must inspect them both at the surface and below the water before
they resume operations, he says, to ensure there was no damage. However, an
even bigger question, Yergin wrote, is the status of the 53,000 kilometers of
underwater pipelines in the Gulf, which are very vulnerable to mudslides,
as energy companies learned last year following Hurricane Ivan, when undersea
mudslides damaged pipelines and knocked platforms off their moorings. It will
likely take some time for remotely operated underwater vehicles to assess damages
to all of the lines.
Still, although the national average for gasoline prices rose from $2.29 a gallon
to $3.06 from Aug. 1 to Sept. 5, according to EIA, shortages were minimal. Following
Katrina, when refiners began running low on oil to turn into gasoline, the Bush
administration opened the strategic petroleum reserve, loaning 9.1 million barrels
of oil to refiners. To ease globally tight supplies, the International Energy
Agency required an additional 2 million barrels of oil a day be released into
the open market for all of September; half of that amount came from the U.S.
reserve.
Theres no question that opening the reserve played a very important
role in easing the gas prices and shortages immediately following the
hurricane, Felmy says. Other changes the Bush administration suggested, he says,
such as relaxing the rules about summer blends of gasoline to allow
lower grades of gasoline to be sold, and allowing foreign oil tankers to transport
oil from one U.S. port to another, also helped to ease the situation. Despite
the relief, what gas prices will do is impossible to say, he says,
especially as prices are so dependent on unpredictable consumer behavior.
The week following the hurricane, we saw absurd rumors about the nation
running out of gas or that gas stations would be closing, so consumers rushed
out to fill their tanks, whether they needed gas or not, Felmy says. A
rush of demand like that is enough to trigger gas shortages and drive prices
sharply higher. Consumers can drain the system dry even when everything is working
well, so we just have to hope that people are smart enough to not add
pressure to an already taut system.
Also, price controls and rations of gasoline ideas that have been bantered
about in many states and actually enacted in Hawaii are very bad
ideas, Felmy says. Such controls, he says, can cause an imbalance in supplies
and lead to consumer panic.
Instead, Felmy says, government leaders need to promote conservation
from inflating tires properly and driving slower to carpooling or taking public
transportation to decrease the demand for petroleum. The government also
needs to diversify the energy infrastructure, he says, by building new pipelines,
increasing refining capacity and drilling for more oil.

Lisa Corathers, the Manganese Commodity Specialist for the U.S. Geological Survey, has compiled the following information about manganese, an extremely versatile mineral with many applications in the manufacturing of iron, steel, aluminum alloys, batteries and chemicals.
Manganese is one of the most important ferrous metals and one of the few for
which the United States is totally dependent on imports. It is a black, brittle
element predominantly used in metallurgical applications as an alloying addition,
particularly in steel and cast iron production, which together provide the largest
market for manganese (about 83 percent). It is also used as an alloy with nonferrous
metals such as aluminum and copper. Nonmetallurgical applications of manganese
include battery cathodes, soft ferrite magnets used in electronics, micronutrients
found in fertilizers and animal feed, water treatment chemicals, and a colorant
for bricks and ceramics.
Manganese is the 12th most abundant element in Earths crust, at about
0.1 percent; however, it is not found free in nature. Deposits occur on all
land areas, deep ocean floors, other marine locations and on lake bottoms. Economically
significant manganese deposits are of two general types marine chemical
sediments and secondary enrichment deposits.
Estimated world manganese ore reserves total 380 million metric tons, and leading
producers are South Africa, Australia, Gabon, Brazil, Ukraine and China. For
manganese ores to be commercially produced, the ore must contain 35 percent
manganese or more, but the United States does not possess such reserves. As
a result, manganese ore is not mined in the United States, except for recovery
of ultra low-grade manganese schists that are used for coloring bricks and are
mined at the Grover and Martin mines in South Carolina.
Manganese ferroalloy production waxed and waned in the United States during
the 1900s. During the last quarter of the 20th century, manganese ferroalloy
production and the number of producers decreased because of global competition.
Production continued only at Eramets plant in Marietta, Ohio, at the turn
of the 21st century. Since 2002, two other companies have produced silicomanganese
sporadically Highlanders Alloys LLC in New Haven, W.Va., and Globe Metallurgical
Inc., in Beverly, Ohio although neither is currently producing. In a
similar fashion, manganese metal production in the United States diminished
in the mid-1980s, with production ceasing altogether by mid-2001.
Because it is essential to steel production, a continued supply of manganese
materials is vital to any defense effort as well as to maintenance and growth
of an industrial economy. Concerns about the manganese supply led the U.S. federal
government to establish a considerable manganese stockpile following World War
II. In 1965, the federal government began selling stockpiled manganese materials
determined to be in excess. The manganese content of manganese inventories being
held by the federal government at year-end 2003 was estimated to be more than
1.03 million metric tons. Even with shipments from the government stockpile
and domestic production of some manganese materials, the United States has been
reliant upon imports for 100 percent of its manganese needs since 1985.
In 2003, the apparent consumption of manganese in the United States was roughly
692,000 tons. The leading sources of manganese imports in 2000 through 2003
were South Africa (36 percent), Gabon (21 percent), Australia (12 percent) and
France (7 percent). World consumption of manganese ore in 2003 approached 23
million tons (gross weight), approximately the same level as world production.
