February 27, 2002: 

The Honorable Dianne Feinstein: 
United States Senate: 

Subject: U.S. Ethanol Market: MTBE Ban in California: 

Dear Senator Feinstein: 

In response to your request, we obtained information on (1) U.S. 
ethanol consumption, supply, and prices, as well as factors that could 
potentially contribute to ethanol price spikes in California, and (2) 
the structure of the U.S. ethanol market and conditions that could 
conceptually affect competition. On February 22, 2002, we briefed your 
staff on the results of our analysis. The enclosed slides formed the 
basis of the briefing we presented. 

The 1990 amendments to the Clean Air Act (CAA) requires that an 
additive (oxygenate) be added to the gasoline used in areas with 
excessive carbon monoxide or ozone pollution to help mitigate these 
conditions. The CAA specifically requires those areas with “severe” 
ozone pollution to use reformulated gasoline, which contains at least 2 
percent oxygen by weight. In California, like most other areas of the 
country, oil refining companies predominantly use the oxygenate methyl 
tertiary butyl ether (MTBE) to meet the CAA requirement. However, 
because MTBE has been detected in ground water, the governor of 
California issued an executive order in March 1999 to ban MTBE in the 
state’s gasoline by the end of 2002. 

In summary, if California decides to use ethanol to replace MTBE, 
ethanol production capacity from 2003 through 2005 could likely satisfy 
U.S. consumption, according to available ethanol industry projections. 
However, if other states also banned MTBE and moved to ethanol, 
consumption could increase significantly and potentially affect the 
industry’s ability to meet demand. Moreover, production capacity 
projections could be overstated because they include not only existing 
plants and plants under construction, but also new plants being 
planned, which may or may not materialize. According to our analysis of 
average monthly data from 1993 through May 1998 (the latest data 
available), U.S. ethanol prices generally ranged from $1 to $1.20 per 
gallon. While prices have been relatively stable to this point, ethanol 
price spikes could occur in California if supplies were disrupted by 
either production or distribution problems. Structurally, the U.S. 
ethanol industry is currently highly concentrated, as measured by the 
Herfindahl-Hirschman Index (HHI), a standard measure of market 
concentration. According to the guidelines of the Federal Trade 
Commission and the U.S. Department of Justice, an HHI above 1800 is 
highly concentrated. Our analysis of January 2002 data from the 
Renewable Fuels Association shows that the U.S. ethanol industry’s HHI 
is 1866. According to economic theory, while high market concentration 
could conceptually limit competition in an industry, this factor alone 
is not necessarily sufficient to determine competitiveness of an 
industry. In addition to market concentration, competition in the 
ethanol market could conceptually be affected by the interaction of a 
variety of other factors, including the cost of initial investment and 
the availability of substitute products. 

Please note that information on future ethanol consumption and supply 
contained in this report reflects the potential implications of the 
proposed ban on MTBE in California by the end of 2002. We did not 
examine the potential impacts of switching to ethanol on California’s 
gasoline market or on U.S. corn prices, both of which could ultimately 
be affected by the MTBE ban. 

This quick snapshot of the industry, based largely on data from other 
federal agencies and industry sources, does not allow us to draw 
conclusions or predict with accuracy the ethanol industry’s capability 
to meet changing demands. As agreed earlier, we will work with your 
staff to address any remaining questions you may have. 

We discuss our methodology in the enclosed slides. We provided portions 
of the statistical information to the relevant federal agencies from 
which we obtained data and they reviewed and verified the data. We 
performed our work in February 2002 in accordance with generally 
accepted government auditing standards. 

As agreed with your office, unless you publicly announce its contents 
earlier, we plan no further distribution of this report until 7 days 
after the date of this letter. At that time, we will send copies to 
interested Members of Congress. This letter will also be available on 
GAO’s home page at [hyperlink, http://www.gao.gov].

information, please call me at (202) 512-3841. Major contributors to 
this letter included Godwin Agbara, John Furutani, Mike Hartnett, John 
Karikari, Mehrzad Nadji, Barbara El Osta, Amy Stewart, and Lynn

Enclosure I: U.S. Ethanol Market: MTBE Ban in California: 

Briefing for Senator Feinstein’s Office: 

February 22, 2002: 

Objectives, Scope, and Methodology: 

Objectives: 

(1) To what extent would ethanol supplies be available to satisfy 
consumption if California bans MTBE after 2002, and what factors could 
potentially contribute to ethanol price spikes in California? 

(2) What is the current structure of the U.S. ethanol market and what 
conditions could conceptually affect competition in the ethanol market? 

Scope: 

* Review focuses on ethanol market and does not analyze impact on 
gasoline or corn markets, both of which could ultimately be affected by 
the MTBE ban and replacement with ethanol as an oxygenate. 

Methodology: 

(1) Interviewed officials, reviewed relevant documents, and analyzed 
data from the ethanol industry and trade organizations, consulting 
firm, petroleum industry, fuel-transportation industry, DOE/EIA, USDA, 
DOT, CRS, the California Energy Commission (CEC). We also estimated 
future U.S. and California ethanol consumption because we did not find 
projections reflecting the MTBE ban in California for this period. 

(2) Reviewed relevant economic literature and interviewed officials 
from the ethanol and petroleum industries as well as academia. 

- We verified portions of the statistical information with relevant 
federal agencies. 

[End of section] 

Background: 

* The 1990 amendments to the Clean Air Act (CAA) requires that an 
additive (oxygenate) be added to the gasoline used in areas with 
excessive carbon monoxide or ozone pollution to help mitigate these 
conditions. 

* The CAA specifically requires those areas with “severe” ozone 
pollution to use reformulated gasoline, which contains at least 2 
percent oxygen by weight. 

* In addition, several areas have voluntarily chosen to use 
reformulated gasoline to help achieve their clean air goals. 

Figure 1: Reformulated Gasoline Program Areas:

Voluntary areas are mainly clustered along the Atlantic coastline in 
the mid-Atlantic states. The Clear Air Act required areas are indicated 
in the following areas: 
Sacramento, California; 
Los Angeles-San Diego, California;

Baltimore, Maryland; 
Philadelphia, Pennsylvania; 
New York City, New York; 
Hartford, Connecticut.

[End of figure] 

* Under the CAA, about 80 percent of the gasoline used in California 
would require oxygenate by 2003.[Footnote 1] 

* In California, like most other affected areas of the country, oil 
refining companies predominantly use the oxygenate methyl tertiary 
butyl ether (MBTE) to meet the CAA requirement.[Footnote 2] 

* Because MTBE has been detected in ground water, the governor of 
California issued an executive order in March 1999 to ban MTBE in the 
state’s gasoline by the end of 2002. 

* According to oil industry officials, ethanol, which is primarily 
produced and used in the Midwest, is expected to become the predominant 
oxygenate used if the ban goes into effect. 

* Other areas of the country where MTBE is currently used may 
subsequently eliminate MTBE, as recommended by a blue-ribbon panel 
commissioned by the U.S. EPA. 

* In addition to its use as a gasoline oxygenate, other fuel-related 
uses of ethanol in the U.S. include use as: a gasohol blend, an octane 
booster, and, to a smaller extent, a straight fuel for ethanol-fueled 
vehicles.[Footnote 3] 

[End of section] 

Ethanol Consumption, Supply, and Price: 

* U.S. ethanol supply, historically mostly from domestic production, 
has been generally sufficient to satisfy consumption. 

* While consumption increased from about 1,040 million gallons per year 
(mg/y) in 1994 to about 1,480 mg/y in 2000, domestic production 
increased from about 1,280 mg/y to about 1,630 mg/y. On average, 
domestic production exceeded consumption in 5 of the 7 years. 

* Moreover, data on production capacity—the combined quantity of 
ethanol that all existing U.S. plants would be capable of 
producing–show producers could have produced more during that period, 
if needed. Production capacity exceeded both consumption and production 
for each of the 7 years from 1994 to 2000.

California Consumption: 

* Banning MTBE in California and switching to ethanol by the end of 
2002 would result in significant increases of ethanol consumption in 
California. 

* We estimate, based on its projected gasoline consumption, that 
California would consume an average of about 880 mg/y of ethanol from 
2003 through 2005, as compared with only about 60mg/y in 2000.[Footnote

[End of figure] 

U.S. Market: 

* We estimate aggregate U.S. consumption of ethanol would increase 
under the ban from about 1,480 mg/y in 2000 to about 2,780 mg/y in 
2005. [Footnote 5] 

* Although a 2001 survey by the California Energy Commission (CEC) 
showed that domestic ethanol producers could build up significant 
capacity that far exceeds the projected consumption between 2003 and 
2005, there are some major caveats.[Footnote 6]

Caveats: 

* Consumption projections assume that only California would ban MTBE 
and switch to ethanol during 2003 through 2005. If other states also 
ban MTBE and switch to ethanol, U.S. ethanol consumption could be 
significantly higher.

* Projected production capacity includes existing plants, those under 
construction or new plants planned. Projected capacity may be lower if 
some existing plants cease production, plants under construction do not 
come on line in time, or some new plants planned do not materialize.

* The future role of imports is unclear: 

- Currently, ethanol imports do not play a significant role in U.S. 
ethanol supplies. 

- Brazil is the world’s largest producer of ethanol, but about 85 
percent of its production capacity cannot be exported. 

- The U.S. generally has a 54 cents/gallon tariff, which discourages 
ethanol imports.

* Based on average monthly data from January 1993 through May 1998 (the 
last year we found data on U.S. ethanol price), the U.S. ethanol price 
has been generally stable, staying approximately within the range of 
$1.00 to $1.20 per gallon, except during a period in 1996 when it 
exceeded this range.[Footnote 7]

Factors That Could Potentially Contribute to Ethanol Price Spikes in 
California: 

* While difficult to predict with certainty, ethanol price spikes may 
occur in California or elsewhere in the U.S. if a disruption at any 
point in the supply system causes a temporary supply shortfall relative 
to demand.[Footnote 8] 

* Oil company officials based in California who plan to use ethanol for 
oxygenate raised concerns about: 

- Availability of excess capacity; 

- Inventory; 

- Transportation. 

Availability of Excess Capacity: 

* In general, if sufficient excess production capacity is not 
available, ethanol producers may not be able to increase production to 
make up for disrupted supplies, a situation that could exacerbate 
potential price spikes. 

* While officials from one oil company stated the ethanol industry has 
estimated that there is currently an estimated 15-20 percent excess 
capacity, future projected excess capacity is, in part, dependent on 
plans for new plants that may or may not materialize. 

Inventory: 

* If ethanol inventory is not sufficient to provide an immediate source 
of supply, it could exacerbate price spikes during supply disruptions. 

* Some officials of oil companies in California told us they plan to 
keep a 10-day inventory in storage but expressed concern about 
potential storage infrastructure constraints in California, such as 
scarcity of land to build storage. 

* About 62 percent of U.S. ethanol inventory available as of December 
2001 was located in the Midwest. 

* Storage in California would be more effective in helping to mitigate 
potential price spikes in the state than out-of-state storage because 
of potential delay in transit.

Transportation: 

* Ethanol imports from other regions are vital. However, any potential 
price spike could be exacerbated if it takes too long for supplies from 
out-of-state (primarily the Midwest, where virtually all the production 
capacity is located) to make their way to California.[Footnote 9]

* Inability to move ethanol quickly from areas where supplies are 
readily available to where it is needed would exacerbate price spikes 
during supply disruptions. 

* According to oil and ethanol industry officials whom we talked to, 
transportation of ethanol from the supply areas of the Midwest to 
California would be mostly by rail and barges, which can take about 1 
to 3 weeks in transit.[Footnote 11] 

* While rail and barge industry officials believe that they have 
sufficient transportation capacity to move ethanol from the Midwest to 
California, some oil industry officials have raised the concern that 
because of Jones Act restrictions, there may not be sufficient vessels 
to move as much ethanol to California as may be needed during supply 
disruptions.[Footnote 12] 

[End of section] 

U.S Ethanol Market Structure and Conditions That Could Conceptually 
Affect Competition: 

* As of January 2002, the U.S. ethanol market consisted of: 

- 44 producers, using 58 plants in19 states, with total existing 
production capacity of more than 2,311 million gallons per year, and; 

- 16 new producers with new plants under construction, with a total 
capacity of 427 million gallons per year, which will slightly lower 
future market shares of large incumbent firms. 

* Market share of the largest eight ethanol producers is currently 71 
percent and is projected to decline to 60 percent as new producers 
complete new plants under construction.

Table 1: Factors That May Enhance or Limit Competition in the U.S. 
Ethanol Market[A]: 

Market concentration: 

Conceptual Market Structure and Firms’ Behavior Factors[Footnote 13]: 
* Pricing coordination is easier if few firms control most of the 
market shares. The FTC/Justice 1992 Horizontal Merger Guidelines regard 
markets with HHI (Herfindahl-Hirschman Index)c above 1800 as “highly 
concentrated.” 
Existing Market Structure and Firms’ Behavior in Ethanol Market 
[Footnote 14][B]: 
* High industry concentration of production capacity based on these 
standard measures of industry concentration for 2002:[D] 
- HHI = 1866; 
- CR4 (Market shares of top 4 firms) = 58%; 
- CR8 (Market shares of top 8 firms) = 71%; 
- Largest firm has 41% market share. 

Market concentration: 
Conceptual Market Structure and Firms’ Behavior Factors[Footnote 13]: 
* High concentration would tend to limit competition; 
Existing Market Structure and Firms’ Behavior in Ethanol Market 
[Footnote 14][B]: 
* Some large producers may have partnered with smaller producers or 
farm coops to market the smaller producer’s supplies of ethanol; thus, 
the concentration ratio may underestimate the actual market 
concentration. However, the market share of the large producers is 
projected to decline. 

Product characteristics: 
Conceptual Market Structure and Firms’ Behavior Factors[Footnote 13]: 
* Product substitutability – more available close substitutes for 
product will enhance competition; 
Existing Market Structure and Firms’ Behavior in Ethanol Market 
[Footnote 14][B]: 
* MTBE and ethanol are the two primary oxygenates; however, MTBE is 
being phased out in California. There are other oxygenates, but because 
of environmental concerns about some of these, the extent to which they 
can substitute ethanol is not clear.[E] 

Product characteristics: 
Conceptual Market Structure and Firms’ Behavior Factors[Footnote 13]: 
* Product homogeneity – When products that are supplied by different 
competitors are perceived by customers not to be qualitatively 
different competition will be enhanced; 
Existing Market Structure and Firms’ Behavior in Ethanol Market 
[Footnote 14][B]: 
* Ethanol products are generally homogeneous. From the customer’s point 
of view, ethanol produced from different plants are identical. 
Costumers buy the products primarily based on the price. 

Product characteristics: 
Conceptual Market Structure and Firms’ Behavior Factors[Footnote 13]: 
* Switching costs – Low costs of switching to other suppliers would 
enhance competition; 
Existing Market Structure and Firms’ Behavior in Ethanol Market 
[Footnote 14][B]: 
* Some customers we interviewed indicated that switching from one 
ethanol vendor to another was not feasible for them. er customers 
typically have contracts with multiple ethanol suppliers (about 2 to 3 
suppliers) and do not incur significant costs in switching to other 
suppliers. 

Entry-related conditions: 
Conceptual Market Structure and Firms’ Behavior Factors[Footnote 13]: 
* Economies of scale or scope[F] – could lower per unit costs, 
potentially lowering prices and discourage entry by smaller suppliers; 
Existing Market Structure and Firms’ Behavior in Ethanol Market 
[Footnote 14][B]: 
* One agricultural economist we interviewed stated that dry-mill plants 
reach economies of scale at about 30-40 million gallons per year, while 
wet-mill plants require about 100 million gallons per year. Dry-mill 
plants can be economical at a smaller scale than wet-mill plants;[G] 
* Firms can realize economies of scope from producing fuel-grade, 
beverage-grade, or industrial-grade ethanol. Production of other corn 
by-products together can lower per unit production costs to millers. 

Entry-related conditions: 
Conceptual Market Structure and Firms’ Behavior Factors[Footnote 13]: 
* Capital Costs: 
- Expansion vs. new plants – Higher costs of new plants as opposed to 
expansion of existing plants discourages entries by new firms; 
- Initial investment costs – A higher initial cost of investment 
discourages new entry; 
Existing Market Structure and Firms’ Behavior in Ethanol Market 
[Footnote 14][B]: 
* Incumbent firms have a cost advantage over new entrants because an 
expansion costs substantially less than a new mill plant. 
* For a dry-mill plant, the costs are estimated to be between $1.50 - 
$2.50 per annual gallon. A wet-mill plant can be built for about $3.00 
per gallon. According to some experts, the initial capital costs of a 
dry-mill plant would not be prohibitive. These costs, however, do not 
include capital costs for distribution infrastructure. 

Entry-related conditions: 
Conceptual Market Structure and Firms’ Behavior Factors[Footnote 13]: 
* Entry time – Shorter entry time can enhance competition. According to 
FTC Merger Guidelines, entry time that is less than 2 years would not 
be a barrier to entry. 
Existing Market Structure and Firms’ Behavior in Ethanol Market 
[Footnote 14][B]: 
* It takes about 15 to 20 months to build a new dry mill corn ethanol 
plant. With available financing the time can be reduced to 1 year. 
Entry-related conditions: 
Conceptual Market Structure and Firms’ Behavior Factors[Footnote 13]: 
* Excess capacity – Excess capacity used as a strategy to deter entry 
would limit competition. 
Existing Market Structure and Firms’ Behavior in Ethanol Market 
[Footnote 14][B]: 
* The average capacity utilization rate in this market was about 84% 
over the years 1994-2000. According to the California Energy 
Commission, this spare capacity was concentrated among the largest 
producers. 

Entry-related conditions: 
Conceptual Market Structure and Firms’ Behavior Factors[Footnote 13]: 
* Marketing/technological barriers -Incumbents marketing or 
technological advantages could inhibit competition. 
Existing Market Structure and Firms’ Behavior in Ethanol Market 
[Footnote 14][B]: 
* Some large suppliers (e.g., ADM) have strong name recognition in the 
ethanol market. On the other hand, according to ethanol engineering and 
construction firms, there are no technical and engineering constraints 
to expanding ethanol construction capacity. 

Market rivalries: 
Conceptual Market Structure and Firms’ Behavior Factors[Footnote 13]: 
* Uniformity of firm size -Asymmetric/different sizes of suppliers may 
encourage aggressive pricing behavior by some suppliers; on the other 
hand, it could promote tacit coordination among suppliers through price 
leadership. 
Existing Market Structure and Firms’ Behavior in Ethanol Market 
[Footnote 14][B]: 
* Based on capacity, the ethanol market has one dominant and many 
smaller or fringe suppliers. 

Market rivalries: 
Conceptual Market Structure and Firms’ Behavior Factors[Footnote 13]: 
* Contracting - Transaction prices based on private contracts could 
facilitate competitive pricing by suppliers. 
Existing Market Structure and Firms’ Behavior in Ethanol Market 
[Footnote 14][B]: 
* In general, ethanol market prices are based on 4-6 months contracts 
with terms that are not made public. 

[A] This table is intended to discuss several market structure and 
behavioral factors as applied to the ethanol market. However, the 
overall competitive conditions or price implications for the U.S. 
ethanol market will depend on the interplay of all these factors and 
cannot be determined by any one factor alone. 

[B] Each factor is discussed assuming all other factors as well as 
state and federal regulations affecting ethanol production remain the 
same. 

[C] The Herfindahl-Hirschman index is a measure of firm concentration 
that describes the size-distribution or the relative importance of both 
small and large firms in an industry. It is defined as the sum of the 
squares of the market shares of the firms in an industry. 

[D] Market shares are based on GAO’s analysis of Renewable Fuels 
Association data. 

[E] Although about 95% of oxygenates in gasoline consist of MTBE and 
ethanol, there are also other oxygenates approved for blending. These 
include TAME (tertiary amyl methyl ether), ETBE (ethyl tertiary butyl 
ether), DIPE (di-iso propyl ether), and TBA (tertiary butyl alcohol). 
Since the first three also contain ethers, they also, like MTBE, raise 
environmental concerns. 

[F] Economies of scale refers to the reduction in production costs per 
unit as the firm size increases. Economies of scope exist when it is 
less costly for one firm to produce two separate products than two 
firms to produce them separately. 

[G] There are two main production processes in the ethanol industry: 
wet milling and dry milling. Plants using wet milling have greater 
production capacities, are more capital intensive, and produce a 
greater variety of products than dry milling plants. The dry milling 
process traditionally generates only two products—ethanol and DDG, an 
animal feed product.

Other Factors That May Enhance or Limit Competition in the U. S. 
Ethanol Market: 

* High market power of customers relative to suppliers tends to lower 
the purchase price. 

* Frequent orders by customers enable rival suppliers to react faster 
to each others’ price. 

* Volatile demand or costs make it difficult for suppliers to detect 
other suppliers that are offering low prices. 

* Vertical relationships by suppliers across the different production 
and distribution levels (e.g., between corn and ethanol productions, 
ethanol producers and transportation modes, etc.) could make it 
difficult for smaller firms to compete in the ethanol production 
market. On the other hand, the vertical relationships could lower costs 
to buyers. 

* Import competition from other international ethanol producers is 
limited.

Footnotes: 

[1] California already uses a special gasoline formulation, called 
California Air Resources Board gasoline (CARB), that is more stringent 
than the federally mandated specifications. 

[2] MTBE is a chemical compound that is manufactured by the chemical 
reaction of methanol and isobutylene. MTBE is produced in very large 
quantities (over 200,000 barrels per day in the U.S. in 1999) and is 
almost exclusively used as a fuel additive in motor gasoline. 

[3] Gasohol is a motor fuel that is blended with up to 10 percent 
ethanol and 90 percent gasoline. Octane in gasoline helps to improve 
the combustion properties of the fuel. 

[4] California's ethanol consumption projections are based on 
historical and an annual growth of 1.1 percent for gasoline (using data 
from 1990 to 2000) and 5.7 percent volume of ethanol requirement. 

[5] U.S. ethanol consumption projections are based on historical and an 
annual growth rate of 5.1 percent of ethanol for the rest of the U.S., 
excluding California (using data from 1993 to 2000), plus the 
projections for California's ethanol consumption. 

[6] According to the CEC, the results of this survey, including the 
production capacity projections, represent the most complete inventory 
of current and likely near-term U.S. ethanol producers available as of 
August 2001. 

[7] According to an agricultural economist at USDA whom we interviewed, 
ethanol prices spiked during this period because of production declines 
caused mostly by unusually sharp increases in the price of corn, which 
is a major input into ethanol production. 

[8] There is no standard definition of price spikes. However, in a 
previous report—U.S. General Accounting Office, Motor Fuels: California 
Gasoline Price Behavior [hyperlink, http://www.gao.gov/products/GAO/RCED-00-12] (Washington, DC: April 28, 
2000)—we defined gasoline price spike as a price increase of at least 6 
cents a gallon in a relatively short period of time—from 4 to 21 weeks. 

[9] U.S. ethanol is produced largely in the Midwest corn belt because 
it is generally less expensive to produce ethanol close to the 
feedstock supply. About 90 percent of ethanol is produced from corn. 

[10] According to EIA, PADD is the geographic aggregation of the 50 
states and the District of Columbia into five districts originally 
defined during World War II for purposes of administering oil 
allocation. 

[11] A pipeline would be the fastest and most economical mode of 
transporting ethanol, but shipping ethanol by pipeline is not feasible 
because of insufficient volume and technical problems associated with 
such shipments. Moreover, there is currently no pipeline connecting the 
Midwest to California. 

[12] The Jones Act, 46 U.S.C., appendix 883, requires the use of 
American vessels to transport merchandise between points in the United 
States. 

[13] The conceptual market structure and firms’ behavior factors are 
based on economic theory. See for example, “Economics of Strategy”, by 
David Besanko, David Dranove, and Mark Shanley (New York: John Wiley & 
Sons, Inc. 1996), p.376. 

[14] The existing market structure and firms’ behavior are based on 
analysis of data for ethanol producers, discussions and interviews with 
oil companies, relevant trade associations, other federal government 
agencies, and relevant economic literature.
