Federal Financial Management, Government Information, Federal 
Services, and International Security, Committee on Homeland Security 
and Governmental Affairs, U.S. Senate. 

Why GAO Did This Study: 

On April 20, 2010, an explosion at the mobile offshore drilling unit 
Deepwater Horizon resulted in a massive oil spill in the Gulf of 
Mexico. The spill’s total cost is unknown, but may result in 
considerable costs to the private sector, as well as federal, state, 
and local governments. The Oil Pollution Act of 1990 (OPA) set up a 
system that places the liability—up to specified limits—on the 
responsible party. The Oil Spill Liability Trust Fund (Fund), 
administered by the Coast Guard, pays for costs not paid for by the 
responsible party. 

GAO previously reported on the Fund and factors driving the cost of 
oil spills and is beginning work on the April 2010 spill. This 
testimony focuses on (1) how oil spills are paid for, (2) the factors 
that affect major oil spill costs, and (3) implications of major oil 
spill costs for the Fund. It is largely based on GAO’s 2007 report, 
for which GAO analyzed oil spill cost data and reviewed documentation 
on the Fund’s balance and vessels’ limits of liability. To update the 
report, GAO obtained information from and interviewed Coast Guard 
officials. 

What GAO Found: 

OPA places the primary burden of liability for the costs of oil spills 
on the responsible party in return for financial limitations on that 
liability. Thus, the responsible party assumes the primary burden of 
paying for spill costs—which can include both removal costs (cleaning 
up the spill) and damage claims (restoring the environment and 
compensating parties that were economically harmed). To pay both the 
costs above this limit and costs incurred when a responsible party 
does not pay or cannot be identified, OPA authorized use of the Fund, 
up to a $1 billion per spill, which is financed primarily from a per-
barrel tax on petroleum products. The Fund also may be used to pay for 
natural resource damage assessments and to monitor the recovery 
activities of the responsible party, among other things. While the 
responsible party is largely paying for the current spill’s cleanup, 
Coast Guard officials said that they began using the Fund—which 
currently has a balance of $1.6 billion—in May 2010 to pay for certain 
removal activities in the Gulf of Mexico. 

Several factors, including location, time of year, and type of oil, 
affect the cleanup costs of noncatastrophic spills. Although these 
factors will certainly affect the cost of the Gulf spill—which is 
unknown at this time—in this spill, additional factors such as the 
magnitude of the oil spill will impact costs. These factors can affect 
the breadth and difficulty of recovery and the extent of damage in the 
following ways: 

* Location. A remote location can increase the cost of a spill because 
of the additional expense involved in mounting a remote response. A 
spill that occurs close to shore can also become costly if it involves 
the use of manual labor to remove oil from sensitive shoreline habitat. 

* Time of year. A spill occurring during fishing or tourist season 
might carry additional economic damage, or a spill occurring during a 
stormy season might prove more expensive because it is more difficult 
to clean up than one occurring during a season with generally calmer 
weather. 

* Type of oil. Lighter oils such as gasoline or diesel fuels dissipate 
and evaporate quickly—-requiring minimal cleanup-—but are highly toxic 
and create severe environmental impacts. Heavier oils such as crude 
oil do not evaporate and, therefore, may require intensive structural 
and shoreline cleanup. 

Since the Fund was authorized in 1990, it has been able to cover costs 
not covered by responsible parties, but risks and uncertainties exist 
regarding the Fund’s viability. For instance, the Fund is at risk from 
claims resulting from spills that significantly exceed responsible 
parties’ liability limits. Of the 51 major oil spills GAO reviewed in 
2007, the cleanup costs for 10 exceeded the liability limits, 
resulting in claims of about $252 million. In 2006, Congress increased 
liability limits, but for certain vessel types, the limits may still 
be low compared with the historic costs of cleaning up spills from 
those vessels. The Fund faces other potential risks as well, including 
ongoing claims from existing spills, claims related to sunken vessels 
that may begin to leak oil, and the threat of a catastrophic spill-—
such as the recent Gulf spill. 

What GAO Recommends: 

In 2007, GAO recommended that the Coast Guard (1) adjust liability 
limits for inflation and (2) determine whether liability limits should 
vary by vessel type. The Coast Guard agreed with both recommendations 
and implemented the former but not the latter recommendation.

Mr. Chairman, Ranking Member McCain, and Members of the Subcommittee: 

I appreciate the opportunity to be here today to discuss the costs of 
major oil spills and the potential impacts on the Oil Spill Liability 
Trust Fund (Fund). On April 20, 2010, an explosion from a well site at 
which the mobile offshore drilling unit (MODU), Deepwater Horizon, had 
been drilling resulted in a spill of national significance in the Gulf 
of Mexico, which is, to date, only partially contained. Since the 
explosion occurred, oil has been leaking into the Gulf of Mexico at an 
estimated rate of between 12,000 and 19,000 barrels per day, according 
to the National Incident Command's Flow Rate Technical Group, making 
this one of the largest, if not the largest spill in U.S. waters to 
date.[Footnote 1] BP, which leased the Deepwater Horizon at the time 
of the explosion, continues to try to contain the leak. The total cost 
of cleaning up this massive and potentially unprecedented spill, the 
untold damage to the environment, as well as the potential impact to 
the livelihood and the economic status of the region, will be 
undetermined for some time. However, current estimates suggest that 
spill cleanup and related damages claims will be in the tens of 
billions of dollars--well beyond the costs of the Exxon Valdez. This 
spill and future spills all have the potential to result in 
considerable costs to the private sector, as well as federal, state, 
and local governments. 

The Oil Pollution Act of 1990 (OPA),[Footnote 2] which was enacted 
after the Exxon Valdez spill in 1989, established a "polluter pays" 
system that places the primary burden of liability for the costs of 
spills up to a statutory maximum, on the party responsible. OPA also 
established the Fund to pay for oil spill costs when the responsible 
party cannot or does not pay.[Footnote 3] The Fund is financed 
primarily from a per-barrel tax on petroleum products either produced 
in the United States or imported from other countries and administered 
by the National Pollution Funds Center (NPFC) within the U.S. Coast 
Guard. While this system is well understood, the total costs involved 
in responding to oil spills are less clear. Costs paid by the Fund are 
required to be documented and reported, but the costs paid by the 
party responsible for the spill are not required to be reported. 
[Footnote 4] The resulting lack of information about the total cost of 
spills, the significant claims made on the Fund to cover the costs 
beyond the established OPA liability limits borne by the responsible 
party, and the potential impact of a catastrophic spill of 
unprecedented costs, have all raised concerns about the Fund's long-
term viability. 

Mr. Chairman, in response to your request, we are just beginning work 
related to the April 2010 spill and its implications for the Fund. 
However, we have done considerable work looking at the cost of major 
spills in recent years and the factors that contribute to making 
spills particularly expensive to clean up and mitigate. While our 
previous work focused on spills from vessels and not offshore 
facilities, it is likely that many of the same factors that we 
identified that affect the cost of the oil spills will apply to the 
current oil spill. Additionally, our previous work identified several 
potential risks to the Fund and made recommendations to the Commandant 
of the Coast Guard to address some of the risks. 

My remarks today are intended to provide a context for looking at the 
nation's approach to paying the costs of such spills. Specifically, my 
testimony focuses on (1) how oil spills are paid for, (2) the factors 
that affect major oil spill costs, and (3) the implications of major 
oil spill costs for the Oil Spill Liability Trust Fund.[Footnote 5] My 
comments are based primarily on our September 2007 report on oil spill 
costs, which was issued to the Senate Committee on Commerce, Science, 
and Transportation, and the House Committee on Transportation and 
Infrastructure.[Footnote 6] In our 2007 report, we determined that 
there were 51 major oil spills--with removal costs and damage claims 
totaling at least $1 million--that occurred in U.S. waters from 1990 
through 2006.[Footnote 7] Collectively, from public and nonpublic 
sources, we estimated that responsible parties and the Fund have paid 
between approximately $860 million and $1.1 billion to clean up these 
spills and compensate affected parties. Responsible parties paid 
between about 72 to 78 percent of these costs. The 51 major spills 
(exceeding $1 million in total costs) we identified, which constituted 
about 2 percent of the 3,389 vessel spills that occurred from 1990 to 
2006, varied greatly from year to year in number and cost and showed 
no discernible trends in frequency or size.[Footnote 8] 

In preparing our September 2007 report we analyzed oil spill removal 
cost and claims data from NPFC, the National Oceanic and Atmospheric 
Administration's (NOAA) Damage Assessment, Remediation, and 
Restoration Program, and the Department of the Interior's (DOI) 
Natural Resource Damage Assessment and Restoration Program and U.S. 
Fish and Wildlife Service. We also analyzed cost data obtained from 
vessel insurers and through contract with Environmental Research 
Consulting.[Footnote 9] We also interviewed NPFC, NOAA, and state 
officials responsible for oil spill response, as well as industry 
experts and representatives from key industry associations and a 
vessel owner. In addition, we reviewed documentation from the NPFC 
regarding the Fund balance and vessels' limits of liability. Earlier 
this month, we obtained updated information from and interviewed NPFC 
officials to update our September 2007 report's findings and to gather 
information on the recent oil spill in the Gulf of Mexico. In 
addition, we have just started work on the Oil Spill Liability Trust 
Fund at the request of the Chairman of this Subcommittee and other 
congressional members. 

Summary: 

OPA establishes a "polluter pays" system that is intended to act as a 
deterrent by placing the primary burden of liability[Footnote 10] for 
the costs of spills on the party responsible for the spill in return 
for financial limitations on that liability.[Footnote 11] Under this 
system, the responsible party assumes, up to a specified limit that is 
subject to certain conditions, the burden of paying for spill costs-- 
which can include both removal costs (cleaning up the spill) and 
damage claims (restoring the environment and payment of compensation 
to parties that were economically harmed by the spill). Above the 
specified limit, which varies depending on the type of vessel or 
facility, the responsible party is no longer financially liable. 
Responsible parties are liable without limit, however, if the oil 
discharge is the result of gross negligence or willful misconduct, or 
a violation of federal operation, safety, or construction regulations. 
To pay costs above the limit of liability, as well as to pay costs 
when a responsible party does not pay or cannot be identified, OPA 
authorized use of the Fund, which is financed primarily from a per-
barrel tax on petroleum products either produced in the United States 
or imported from other countries. Offshore facilities' limit of 
liability is all removal costs plus $75 million for damage claims. 
[Footnote 12] The Fund also may be used to pay for natural resource 
damage assessments and to monitor the recovery activities of the 
responsible party, among other things. Coast Guard officials said that 
they began using the Fund in May 2010 to pay for removal activities in 
the Gulf of Mexico. 

Several factors affect the costs of a noncatastrophic spill, according 
to industry experts and agency officials and the studies we reviewed-- 
the spill's location, the time of year it occurs, and the type of oil 
spilled. Additionally, the magnitude of the oil spill will also impact 
costs of the Deepwater Horizon spill. A remote location, for example, 
can increase the cost of a spill because of the additional expense 
involved in mounting a remote response. Similarly, a spill that occurs 
close to shore rather than further out at sea can become more 
expensive because it may involve the use of manual labor to remove oil 
from sensitive shoreline habitat. Time also has situation-specific 
effects, in that a spill that occurs at a particular time of year 
might involve a much greater cost than a spill occurring in the same 
place but at a different time of year. For example, a spill occurring 
during fishing or tourist season might carry additional economic 
damage, or a spill occurring during a typically stormy season might 
prove more expensive because it is more difficult to clean up than one 
occurring during a season with generally calmer weather. The specific 
type of oil affects costs because the type of oil can affect the 
amount of cleanup needed and the amount of natural resource damage 
incurred. Lighter oils such as gasoline or diesel fuels dissipate and 
evaporate quickly--requiring minimal cleanup--but are highly toxic and 
create severe environmental impacts. Heavier oils such as crude oil do 
not evaporate and, therefore, may require intensive structural and 
shoreline cleanup; and while they are less toxic than light oils, 
heavy oils can harm waterfowl and fur-bearing mammals through coating 
and ingestion. Each spill's cost reflects the particular mix of these 
factors, and no factor is clearly predictive of the outcome. Although 
the total costs of the Gulf Coast spill will be unknown for some time, 
many of the same key factors such as location, time of year, oil type, 
and the magnitude of the oil spilled, will certainly impact the costs 
of this spill. For example, the spill occurred in the spring in an 
area of the country--the Gulf Coast--that relies heavily on revenue 
from tourism and the commercial fishing industry. According to one 
expert, the loss in revenue from suspended commercial and recreational 
fishing in the Gulf Coast states is currently estimated at $144 
million per year.[Footnote 13] 

Since it was authorized in 1990, the Fund has been able to cover costs 
that responsible parties have not paid from noncatastrophic spills, 
but risks and uncertainties exist regarding the Fund's viability. In 
particular, the Fund is at risk from claims resulting from spills that 
significantly exceed responsible parties' liability limits. The effect 
of such spills can be seen among the 51 major oil spills we identified 
in 2007: 10 of them exceeded the limit of liability, resulting in 
claims of about $252 million on the Fund. In the Coast Guard and 
Maritime Transportation Act of 2006, Congress increased these 
liability limits,[Footnote 14] but additional attention to the limits 
appears warranted because the liability limits for certain vessel 
types may still be disproportionately low compared with their historic 
spill cost. For example, of the 51 major spills since 1990, 15 
resulted from tank barges. The average cost for these 15 tank barge 
spills was about $23 million--more than double the average liability 
limit ($10.3 million) for these vessels. In its August 2009 report 
examining oil spills that exceeded the limits of liability, the Coast 
Guard had similar findings on the adequacy of some of the current 
limits and their potential effect on the Fund. Aside from issues 
related to limits of liability, the Fund faces other potential drains 
on its resources, including ongoing claims from existing spills, 
claims related to already-sunken vessels that may begin to leak oil, 
and the threat of a catastrophic spill--such as the Deepwater Horizon--
which could have a significant impact on the Fund's viability. 

In our September 2007 report, we recommended that the Commandant of 
the Coast Guard (1) determine whether and how liability limits should 
be changed, by vessel type, and make recommendations about these 
changes to Congress and (2) adjust the limits of liability for vessels 
every 3 years to reflect changes in inflation, as appropriate. The 
Department of Homeland Security (DHS), including the Coast Guard, 
generally agreed with the report's contents and agreed with the 
recommendations. In July 2009, the Commandant of the Coast Guard 
implemented our recommendation to adjust limits of liability for 
vessels every 3 years to reflect changes in inflation,[Footnote 15] 
but to date, has not implemented our recommendation to determine 
whether and how liability limits should be changed by vessel type and 
make recommendations about these changes to Congress. We continue to 
believe that adjusting liability limits for particular vessel types, 
notably tank barges, would ensure that the "polluter pays" principle 
is carried out in practice. 

The Primary Burden of Liability for the Costs of Oil Spills Is on the 
Responsible Party, up to Specified Limits: 

OPA establishes a "polluter pays" system that places the primary 
burden of liability for the costs of spills on the party responsible 
for the spill in return for financial limitations on that liability. 
Under this system, the responsible party assumes, up to a specified 
limit, the burden of paying for spill costs--which can include both 
removal costs (cleaning up the spill) and damage claims (restoring the 
environment and payment of compensation to parties that were 
economically harmed by the spill). Above the specified limit, the 
responsible party generally is no longer financially liable. 
Responsible parties are liable without limit, however, if the oil 
discharge is the result of gross negligence or willful misconduct, or 
a violation of federal operation, safety, and construction 
regulations. OPA's "polluter pays" system is intended to provide a 
deterrent for responsible parties who could potentially spill oil by 
requiring that they assume the burden of responding to the spill, 
restoring natural resources, and compensating those damaged by the 
spill, up to the specified limit of liability. (See table 1 for the 
limits of liability for vessels and offshore facilities.) 

In general, liability limits under the OPA depend on the kind of 
vessel or facility from which a spill comes. For an offshore facility, 
liability is limited to all removal costs plus $75 million. For tank 
vessels, liability limits are based on the vessel's tonnage and hull 
type. In both cases, certain circumstances, such as gross negligence, 
eliminate the caps on liability altogether. According to the Coast 
Guard, the leaking well in the current spill is an offshore facility. 
As noted earlier, pursuant to OPA, the liability limit for offshore 
facilities is all removal costs plus $75 million for damage claims. 
The Coast Guard also notes that liability for any spill on or above 
the surface of the water in this case would be between $65 million and 
$75 million. The range derives from a statutory division of liability 
for mobile offshore drilling units.[Footnote 16] For spills on or 
above the surface of the water, mobile offshore drilling units are 
treated first as tank vessels up to the limit of liability for tank 
vessels and then as offshore facilities.[Footnote 17]

[End of table] 

For example, if an offshore facility's limit of liability is $75 
million (not counting removal costs, for which there is unlimited 
liability for offshore facilities) and a spill resulted in $100 
million in costs, the responsible party has to pay up to $75 million 
in damage claims--leaving $25 million in costs beyond the limit of 
liability.[Footnote 18] Under OPA, the authorized limit on federal 
expenditures for a response to a single spill is currently set at $1 
billion, and natural resource damage assessments and claims may not 
exceed $500 million. OPA requires that responsible parties must 
demonstrate their ability to pay for oil spill response up to 
statutorily specified limits. Specifically, by statute, with few 
exceptions, offshore facilities that are used for exploring for, 
drilling for, producing, or transporting oil from facilities engaged 
in oil exploration, drilling, or production are required to have a 
certificate of financial responsibility that demonstrates their 
ability to pay for oil spill response up to statutorily specified 
limits. If the responsible party denies a claim or does not settle it 
within 90 days, a claimant may commence action in court against the 
responsible party, or present the claim to the NPFC. 

OPA also provides that the Fund[Footnote 19] can be used to pay for 
oil spill removal costs and damages when those responsible do not pay 
or cannot be located. This may occur when the source of the spill and, 
therefore, the responsible party is unknown, or when the responsible 
party does not have the ability to pay. In other cases, since the cost 
recovery can take a period of years, the responsible party may become 
bankrupt or dissolved. 

NPFC manages the Fund by disbursing funds for federal cleanup, 
monitoring the sources and uses of funds, adjudicating claims 
submitted to the Fund for payment, and pursuing reimbursement from the 
responsible party for costs and damages paid by the Fund. The Coast 
Guard is responsible for adjusting vessels' limits of liability for 
significant increases in inflation and for making recommendations to 
Congress on whether other adjustments are necessary to help protect 
the Fund.[Footnote 20] DOI's Minerals Management Service is 
responsible for adjusting limits of liability of offshore facilities. 

Response to large oil spills is typically a cooperative effort between 
the public and private sector, and there are numerous players who 
participate in responding to and paying for oil spills. To manage the 
response effort, the responsible party, the Coast Guard, EPA, and the 
pertinent state and local agencies form the unified command, which 
implements and manages the spill response.[Footnote 21] 

OPA defines the costs for which responsible parties are liable and the 
costs for which the Fund is made available for compensation in the 
event that the responsible party does not pay or is not 
identified.[Footnote 22] These costs, or "OPA compensable" costs, are 
of two main types: 

* Removal costs: Removal costs are incurred by the federal government 
or any other entity taking approved action to respond to, contain, and 
clean up the spill. For example, removal costs include the equipment 
used in the response--skimmers to pull oil from the water, booms to 
contain the oil, planes for aerial observation--as well as salaries 
and travel and lodging costs for responders. 

* Damages caused by the oil spill: Damages that can be compensated 
under OPA cover a wide range of both actual and potential adverse 
effects from an oil spill, for which a claim may be made to either the 
responsible party or the Fund. Claims include natural resource damage 
claims filed by trustees, claims for uncompensated removal costs and 
third-party damage claims for lost or damaged property and lost 
profits, among other things.[Footnote 23] 

The Fund has two major components--the Principal Fund and the 
Emergency Fund. The Principal Fund provides the funds for third-party 
and natural resource damage claims, limit of liability claims, 
reimbursement of government agencies' removal costs, and provides for 
oil spill-related appropriations. A number of agencies--including the 
Coast Guard, EPA, and DOI--receive an annual appropriation from the 
Principal Fund to cover administrative, operational, personnel, and 
enforcement costs. To ensure rapid response to oil spills, OPA created 
an Emergency Fund that authorizes the President to spend $50 million 
each year to fund spill response and the initiation of natural 
resource damage assessments, which provide the basis for determining 
the natural resource restoration needs that address the public's loss 
and use of natural resources as a result of a spill. 

Emergency funds not used in a fiscal year are carried over to the 
subsequent fiscal years and remain available until expended. To the 
extent that $50 million is inadequate, authority under the Maritime 
Transportation Security Act of 2002 grants authority to advance up to 
$100 million from the Fund to pay for removal activities. These 
emergency funds may be used for containing and removing oil from water 
and shorelines, preventing or minimizing a substantial threat of 
discharge, and monitoring the removal activities of the responsible 
party. NPFC officials told us in June 2010 that the emergency fund has 
received the advanced authority of $100 million for the Federal On- 
Scene Coordinator to respond to the spill and for federal trustees to 
initiate natural resource damage assessments along with an additional 
$50 million that had not been apportioned in 2006. Officials said they 
began using emergency funds at the beginning of May to pay for removal 
activities in the Gulf of Mexico.[Footnote 24] 

The Fund is financed primarily from a per-barrel tax on petroleum 
products either produced in the United States or imported from other 
countries. The balance of the Fund (including both the Principal and 
the Emergency Fund) has varied over the years (see figure 1).[Footnote 
25] The Fund's balance generally declined from 1995 through 2006, and 
from fiscal year 2003 through 2007, its balance was less than the 
authorized limit on federal expenditures for the response to a single 
spill, which is currently set at $1 billion. This was in part because 
the Fund's main source of revenue--a $0.05 per barrel tax on U.S. 
produced and imported oil--was not collected for most of the time from 
1995 through 2006.[Footnote 26] However, the Energy Policy Act of 2005 
reinstated the barrel tax beginning in April 2006. [Footnote 27] 
Subsequently, the Emergency Economic Stabilization Act of 2008 
increased the tax rate to $0.08 per barrel through 2016.[Footnote 28] 
The balance in the Fund as of June 1, 2010, was about $1.6 billion. 
[Footnote 29] With the barrel tax once again in place, NPFC 
anticipates that the Fund will be able to cover potential 
noncatastrophic liabilities.[Footnote 30] In 2007 we reported several 
risks to the Fund, including the threat of a catastrophic spill. 
Although the Fund's balance has increased, significant uncertainties 
remain regarding the impact of a catastrophic spill--such as the 
Deepwater Horizon--or multiple catastrophic spills on the Fund's 
viability.

Several Factors, including Location, Time of Year, and Type of Oil, 
Combine in Unique Ways and Affect the Cost of Each Oil Spill: 

Location, time of year, and type of oil are key factors affecting oil 
spill costs of noncatastrophic spills, according to industry experts, 
agency officials, and our analysis of spills. Given the magnitude of 
the current spill, however, the size of this spill will also be a 
factor that affects the costs. Officials also identified two other 
factors that may influence oil spill costs to a lesser extent--the 
effectiveness of the spill response and the level of public interest 
in a spill. In ways that are unique to each spill, these factors can 
affect the breadth and difficulty of the response effort or the extent 
of damage that requires mitigation. 

Location Affects Costs in Different Ways: 

According to state officials with whom we spoke and industry experts, 
there are three primary characteristics of location that affect costs: 

* Remoteness: For spills that occur in remote areas, spill response 
can be particularly difficult in terms of mobilizing responders and 
equipment, and they can complicate the logistics of removing oil from 
the water--all of which can increase the costs of a spill. 

* Proximity to shore: There are also significant costs associated with 
spills that occur close to shore. Contamination of shoreline areas has 
a considerable bearing on the costs of spills as such spills can 
require manual labor to remove oil from the shoreline and sensitive 
habitats. The extent of damage is also affected by the specific 
shoreline location. 

* Proximity to economic centers: Spills that occur in the proximity of 
economic centers can cost more when local services are disrupted. For 
example, a spill near a port can interrupt the flow of goods, 
necessitating an expeditious response in order to resume business 
activities, which could increase removal costs. Additionally, spills 
that disrupt economic activities can result in expensive third-party 
damage claims. 

Time of Year Affects Local Economies and Response Efforts: 

The time of year in which a spill occurs can also affect spill costs-- 
in particular, affecting local economies and response efforts. 
According to several state and private-sector officials with whom we 
spoke, spills that disrupt seasonal events that are critical for local 
economies can result in considerable expenses. For example, spills in 
the spring months in areas of the country that rely on revenue from 
tourism may incur additional removal costs in order to expedite spill 
cleanup, or because there are stricter standards for clean up, which 
increase the costs. The time of year in which a spill occurs also 
affects response efforts because of possible inclement weather 
conditions such as harsh winter storms and even hurricanes that can 
result in higher removal costs because of the increased difficulty in 
mobilizing equipment and personnel to respond to a spill in adverse 
conditions. 

Type of Oil Spilled Affects the Extent of the Response Effort and the 
Amount of Damage: 

The different types of oil can be grouped into four categories, each 
with its own set of effects on spill response and the environment. 
Lighter oils such as jet fuels, gasoline, and diesel fuel dissipate 
and evaporate quickly, and as such, often require minimal cleanup. 
However, these oils are highly toxic and can severely affect the 
environment if conditions for evaporation are unfavorable. For 
instance, in 1996, a tank barge that was carrying home-heating oil 
grounded in the middle of a storm near Point Judith, Rhode Island, 
spilling approximately 828,000 gallons of heating oil (light oil). 
Although this oil might dissipate quickly under normal circumstances, 
heavy wave conditions caused an estimated 80 percent of the release to 
mix with water, with only about 12 percent evaporating and 10 percent 
staying on the surface of the water .[Footnote 31] Natural resource 
damages alone were estimated at $18 million, due to the death of 
approximately 9 million lobsters, 27 million clams and crabs, and over 
4 million fish. 

Heavier oils, such as crude oils and other heavy petroleum products, 
are less toxic than lighter oils but can also have severe 
environmental impacts. Medium and heavy oils do not evaporate much, 
even during favorable weather conditions, and can blanket structures 
they come in contact with--boats and fishing gear, for example--as 
well as the shoreline, creating severe environmental impacts to these 
areas, and harming waterfowl and fur-bearing mammals through coating 
and ingestion. Additionally, heavy oils can sink, creating prolonged 
contamination of the sea bed and tar balls that sink to the ocean 
floor and scatter along beaches. These spills can require intensive 
shoreline and structural clean up, which is time-consuming and 
expensive. For example, in 1995, a tanker spilled approximately 38,000 
gallons of heavy fuel oil into the Gulf of Mexico when it collided 
with another tanker as it prepared to lighter its oil to another ship. 
[Footnote 32] Less than 1 percent (210 gallons) of the oil was 
recovered from the sea, and, as a result, recovery efforts on the 
beaches of Matagorda and South Padre Islands were labor intensive, as 
hundreds of workers had to manually pick up tar balls with shovels. 
The total removal costs for the spill were estimated at $7 million. 

Other Factors also Affect Spill Costs: 

In our 2007 report, we also reported that industry experts cited two 
other factors that also affect the costs incurred during a spill. 

* Effectiveness of Spill Response: Some private-sector experts stated 
that the effectiveness of spill response can affect the cost of 
cleanup. The longer it takes to assemble and conduct the spill 
response, the more likely it is that the oil will move with changing 
tides and currents and affect a greater area, which can increase 
costs. Some experts said the level of experience of those involved in 
the incident command is critical to the effectiveness of spill 
response. For example, they said poor decision making during a spill 
response could lead to the deployment of unnecessary response 
equipment, or worse, not enough equipment to respond to a spill. 
Several experts expressed concern that Coast Guard officials are 
increasingly inexperienced in handling spill response, in part because 
the Coast Guard's mission has been increased to include homeland 
security initiatives. 

* Public interest: Several experts with whom we spoke stated that the 
level of public attention placed on a spill creates pressure on 
parties to take action and can increase costs. They also noted that 
the level of public interest can increase the standards of cleanliness 
expected, which may increase removal costs. 

Key Factors Will Likely Influence Cost of Gulf Coast Spill: 

The total costs of the Deepwater Horizon spill in the Gulf of Mexico 
are currently undetermined and will be unknown for some time even 
after the spill is fully contained. According to a press release from 
BP, as of June 7, 2010, the cost of the response amounted to about 
$1.25 billion, which includes the spill response, containment, relief 
well drilling, grants to the Gulf states, damage claims paid and 
federal costs. Of the $1.25 billion, approximately $122 million (as of 
June 1, 2010) has been paid from the Fund for the response operation, 
according to NPFC officials.[Footnote 33] The total costs will not 
likely be known for a while, as it can take many months or years to 
determine the full effect of a spill on natural resources and to 
determine the costs and extent of the natural resource damage. 
However, the spill has been described as the biggest U.S. offshore 
platform spill in 40 years, and possibly the most costly. 

Our work for this testimony did not include a thorough evaluation of 
the factors affecting the current spill. However, some of the same key 
factors that have influenced the cost of 51 major oil spills we 
reviewed in 2007 will likely have an effect on the costs in the Gulf 
Coast spill. For example, the spill occurred in the spring in an area 
of the country--the Gulf Coast--that relies heavily on revenue from 
tourism and the commercial fishing industry. Spills that occur in 
proximity of tourist destinations like beaches can result in 
additional removal costs in order to expedite spill cleanup, or 
because there are stricter standards for cleanup, which increase the 
costs. In addition, according to an expert, the loss in revenue from 
suspended commercial and recreational fishing in the Gulf Coast states 
is currently estimated at $144 million per year.[Footnote 34] Another 
factor affecting spills' costs is the type of oil. The oil that 
continues to spill into the Gulf of Mexico is a light oil--
specifically "light sweet crude" oil--that is toxic and can create 
long-term contamination of shorelines, and harm waterfowl and fur-
bearing mammals. According to the U.S. Fish and Wildlife Service, many 
species of wildlife face grave risk from the spill, as well as 36 
national wildlife refuges that may be affected. In recent testimony, 
the EPA Deputy Administrator described the Deepwater Horizon spill as 
a "massive and potentially unprecedented environmental disaster." 

The Fund Has Been Able to Cover Costs Not Paid by Responsible Parties, 
but Risks and Uncertainties Remain: 

To date, the Fund has been able to cover costs from major spills that 
responsible parties have not paid, but risks and uncertainties remain. 
We reported in 2007 that the current liability limits for certain 
vessel types, notably tank barges, may have been disproportionately 
low relative to costs associated with such spills. In addition, the 
Fund faced other potential risks to its viability, including ongoing 
claims from existing spills and the potential for a catastrophic oil 
spill. The current spill in the Gulf of Mexico could result in a 
significant strain on the Fund, which currently has a balance of about 
$1.6 billion. 

Further Attention to Limits of Liability Is Needed: 

The Fund has been able to cover costs from major spills that 
responsible parties have not paid, but additional focus on limits of 
liability is warranted. Limits of liability are the amount, under 
certain circumstances, above which responsible parties are no longer 
financially liable for spill removal costs and damage claims, in the 
absence of gross negligence or willful misconduct, or the violation of 
an applicable federal safety, construction, or operating regulation. 
[Footnote 35] If the responsible party's costs exceed the limit of 
liability, the responsible party can make a claim against the Fund for 
the amount above the limit. Major oil spills that exceed a vessel's 
limit of liability are infrequent, but their effect on the Fund can be 
significant. In our 2007 report, we reported that 10 of the 51 major 
oil spills that occurred from 1990 through 2006 resulted in limit-of-
liability claims on the Fund.[Footnote 36] These limit-of-liability 
claims totaled more than $252 million and ranged from less than $1 
million to more than $100 million. Limit-of-liability claims will 
continue to have a pronounced effect on the Fund. NPFC estimates that 
74 percent of claims under adjudication that were outstanding as of 
January 2007 were for spills in which the limit of liability had been 
exceeded. The amount of these claims under adjudication was $217 
million. 

In 2007, we identified two key areas in which further attention to 
these liability limits appeared warranted and made recommendations to 
the Commandant of the Coast Guard regarding both--the need to adjust 
limits periodically in the future to account for significant increases 
in inflation and the appropriateness of some current liability limits. 
Regarding the need to adjust liability limits to account for increases 
in inflation, we reported that the Fund was exposed to about $39 
million in liability claims for the 51 major spills from 1990 through 
2006 that could have been saved if the limits of liability had been 
adjusted for inflation as required by law, and recommended adjusting 
limits of liability for vessels every 3 years to reflect significant 
changes in inflation, as appropriate.[Footnote 37] Per requirements in 
OPA as amended by the Delaware River Protection Act, the Coast Guard 
published an interim rule in July 2009--made final in January 2010-- 
that adjusted vessels' limits of liability to reflect significant 
increases in the Consumer Price Index, noting that the inflation 
adjustments to the limits of liability are required by OPA to preserve 
the deterrent effect and polluter-pays principle embodied in the OPA 
liability provisions.[Footnote 38] DOI has been delegated 
responsibility by the President to adjust the liability limits for 
offshore facilities and this responsibility has been redelegated by 
DOI to the Minerals Management Service.[Footnote 39] To date, these 
liability limits have not been adjusted for inflation. 

The Coast Guard and Maritime Transportation Act of 2006 significantly 
increased the limits of liability.[Footnote 40] Both laws base the 
liability on a specified amount per gross ton of vessel volume, with 
different amounts for vessels that transport oil commodities (tankers 
and tank barges) than for vessels that carry oil as a fuel (such as 
cargo vessels, fishing vessels, and passenger ships). The 2006 act 
raised both the per-ton and the required minimum amounts, 
differentiating between vessels with a double hull, that helps prevent 
oil spills resulting from collision or grounding, and vessels without 
a double hull.[Footnote 41] For example, the liability limit for 
single-hull vessels larger than 3,000 gross tons was increased from 
the greater of $1,200 per gross ton or $10 million to the greater of 
$3,000 per gross ton or $22 million. 

However, our analysis of the 51 major spills showed that the average 
spill cost for some types of vessels, particularly tank barges, was 
higher than the limit of liability, including the new limits 
established in 2006.[Footnote 42] Thus, we recommended that the 
Commandant of the Coast Guard determine whether and how liability 
limits should be changed by vessel type, and make specific 
recommendations about these changes to Congress. In its August 2009 
Annual Report to Congress on OPA liability limits, the Coast Guard had 
similar findings on the adequacy of some of the new limits.[Footnote 
43] The Coast Guard found that 51 spills or substantial threats of a 
spill have resulted or are likely to result in removal costs and 
damages that exceed the liability limits amended in 2006. 
Specifically, the Coast Guard reported that liability limits for tank 
barges and cargo vessels with substantial fuel oil may not 
sufficiently account for the historic costs incurred by spills from 
these vessel types. The Coast Guard concluded that increasing 
liability limits for tank barges and non tank vessels--cargo, freight, 
and fishing vessels--over 300 gross tons would increase the Fund 
balance. With regard to making specific adjustments, the Coast Guard 
said dividing costs equally between the responsible parties and the 
Fund was a reasonable standard to apply in determining the adequacy of 
liability limits.[Footnote 44] However, the Coast Guard did not 
recommend explicit changes to achieve either that 50/50 standard or 
any other division of responsibility. 

Other Challenges Could also Affect the Fund's Condition: 

The Fund also faces several other potential challenges that could 
affect its financial condition: 

* Additional claims could be made on spills that have already been 
cleaned up: Natural resource damage claims can be made on the Fund for 
years after a spill has been cleaned up. The official natural resource 
damage assessment conducted by trustees can take years to complete, 
and once it is completed, claims can be submitted to the NPFC for up 
to 3 years thereafter.[Footnote 45] 

* Costs and claims may occur on spills from previously sunken vessels 
that discharge oil in the future: Previously sunken vessels that are 
submerged and in threat of discharging oil represent an ongoing 
liability to the Fund. There are over 1000 sunken vessels that pose a 
threat of oil discharge.[Footnote 46] These potential spills are 
particularly problematic because in many cases there is no viable 
responsible party that would be liable for removal costs. Therefore, 
the full cost burden of oil spilled from these vessels would likely be 
paid by the Fund. 

* Spills may occur without an identifiable source and, therefore, no 
responsible party: Mystery spills also have a sustained effect on the 
Fund, because costs for spills without an identifiable source--and 
therefore no responsible party--may be paid out of the Fund. Although 
mystery spills are a concern, the total cost to the Fund from mystery 
spills was lower than the costs of known vessel spills in 2001 through 
2004. Additionally, none of the 51 major oil spills was the result of 
discharge from an unknown source. 

* A catastrophic spill could strain the Fund's resources: In 2007, we 
reported that since the 1989 Exxon Valdez spill, which was the impetus 
for authorizing the Fund's usage, no oil spill has come close to 
matching its costs--estimated at $2.2 billion for cleanup costs alone, 
according to the vessel's owner. [Footnote 47] However, as of early 
June, the response for the Deepwater Horizon spill had already totaled 
over $1 billion, according to BP, and to date, the spill has not been 
fully contained. As a result, the Gulf of Mexico spill could easily 
eclipse the Exxon Valdez, becoming the most costly offshore spill in 
U.S. history. The Fund is currently authorized to pay out a maximum of 
$1 billion on a single spill for response costs, with up to $500 
million for natural resource damage claims. Although the Fund has been 
successful thus far in covering costs that responsible parties did not 
pay, it may not be sufficient to pay such costs for a spill--such as 
the Deepwater Horizon--that are likely to have catastrophic 
consequences. While BP has said it will pay all legitimate claims 
associated with the spill, should the company decide it will not or 
cannot pay for the costs exceeding their limit of liability, the Fund 
may have to bear these costs. Given the magnitude of the Deepwater 
Horizon spill, the costs could result in a significant strain on the 
Fund. 

Options for Addressing the Fund's Vulnerabilities: 

Recently, several options have been identified to address the Fund's 
vulnerabilities. In particular, the Congressional Research Service 
(CRS)[Footnote 48] has identified options to address the 
vulnerabilities, and Members of Congress have also introduced 
legislation that would address the risks to the Fund.[Footnote 49] 
These options include: 

* Increasing liability limits. CRS proposes raising the liability caps 
for vessels so that the responsible party would be required to pay a 
greater share of the costs before the Fund is used. In addition, S. 
3305 proposes raising the liability limit for damage claims related to 
offshore facilities from $75 million to $10 billion. 

* Increasing the per-barrel tax. CRS and congressional options include 
increasing the current per-barrel tax used to generate revenue for the 
Fund in order to raise the Fund's balance--H.R. 4213 proposes raising 
the tax from the current $0.08 per barrel to $0.34. According to CRS, 
this option would increase the likelihood that there is sufficient 
money available in the Fund if costs exceed the responsible party's 
liability limits. 

* Including oil owners as liable parties. CRS suggests expanding the 
definition of liable parties to include the owner of the oil being 
transported by a vessel. 

In addition, the Administration announced a proposal on May 12, 2010, 
that addresses several aspects of the response to the Deepwater 
Horizon spill, primarily by changing the way the Fund operates. It 
includes, among other things, proposals to increase the statutory 
limitation on expenditures from the Fund for a single oil spill 
response from $1 billion to $1.5 billion for spill response and from 
$500 million to $750 million per spill for natural resource damage 
assessments and claims. In addition, similar to the CRS and 
congressional proposals, the Administration is proposing an increase 
on the per-barrel tax to $0.09 this year, 7 years earlier than the 
current law requires. 

Mr. Chairman, this concludes my statement. I would be pleased to 
respond to any questions you or other Members of the Subcommittee may 
have.

spills as spills with total removal costs and damage claims that

[6] GAO, Maritime Transportation: Major Oil Spills Occur Infrequently, 
but Risks to the Federal Oil Spill Fund Remain, [hyperlink, 
http://www.gao.gov/products/GAO-07-1085] (Washington, D.C.: Sept. 7, 
2007). The Coast Guard and Maritime Transportation Act of 2006, Pub. 
L. No. 109-241, 120 Stat. 516 (2006), directed us to conduct an 
assessment of the cost of response activities and claims related to 
oil spills from vessels that have occurred since January 1, 1990, for 
which the total costs and claims paid was at least $1 million per 
spill. The mandate required that the report summarize the costs and 
claims for oil spills that have occurred since January 1, 1990, that 
total at least $1 million per spill, and the source, if known, of each 
spill for each year. We were not directed to look at spills from 
offshore facilities. 

[7] Our analysis excluded spills for which final costs were not yet 
known because all claims had not been addressed. 

[8] In order to determine the spill cost estimates for the 51 spills 
in our 2007 report, we obtained the best available cost data from a 
variety of sources because private-sector and total costs for cleaning 
up spills and paying damages are not centrally tracked and maintained. 
We then combined the information that we collected from these various 
sources to develop cost estimates for the oil spills. However, because 
the cost data are somewhat imprecise and the data we collected vary 
somewhat by source, we presented the cost estimates in ranges. The 
lower and higher bounds of the range represent the low-and high-end of 
cost information we obtained. Based on reviews of data documentation, 
interviews with relevant officials, and tests for reasonableness, we 
determined that the data were sufficiently reliable for the purposes 
of our report.

[10] In the case of a vessel, the responsible party is "any person 
owning, operating, or demise chartering the vessel." 33 U.S.C. § 
2701(32)(A). In the case of an offshore facility the responsible party 
is the lessee or permittee of the area in which the facility is 
located or the holder of a right of use and easement granted under 
applicable State law or the Outer Continental Shelf Lands Act...for 
the area in which the facility is located (if the holder is a 
different person than the lessee or permittee)...33 U.S.C. § 
2701(32)(C). NPFC has designated the source of the discharges for this 
incident as BP Exploration and Production, Inc. as lessee for the 
area, and Transocean Holdings, Inc., as the owner of the mobile 
offshore drilling unit, and as such, are responsible parties. To date, 
only BP is paying costs associated with this spill. 

[11] This testimony focuses only on the liability imposed by OPA. 

[12] When responsible parties' costs exceed their limit of liability 
and the limit is upheld--because there was no gross negligence willful 
misconduct, or violations of federal regulations by the vessel owner 
or operator--the responsible party is entitled to file a claim on the 
Fund to be reimbursed for costs in excess of the limit.

[17] The estimate of $65 million is based on the tonnage of the 
Deepwater Horizon and thus the liability that would be calculated for 
it as a tank vessel, and $75 million is the cap on liability for 
offshore facilities. 

[18] When responsible parties' costs exceed their limit of liability 
and the limit is upheld--because there was no gross negligence or 
violations of federal regulations by the vessel owner or operator--the 
responsible party is entitled to file a claim on the Fund to be 
reimbursed for costs in excess of the limit. The NPFC reviews the 
claim to determine which costs are entitled to compensation under and 
the responsible party is reimbursed from the Fund.

Reconciliation Act of 1986, Pub. L. No. 99-509, title VIII, § 8033 
(Oct. 21, 1986) (codified at 26 U.S.C. § 9509), to fund oil spill 
response activities, but Congress did not authorize its use until 
enactment of OPA in 1990.

[23] OPA authorizes the United States, states, and Indian Tribes to 
act on behalf of the public as natural resource trustees for natural 
resources under their respective trusteeship. Trustees often have 
information and technical expertise about the biological effects of 
pollution, as well as the location of sensitive species and habitats 
that can assist the federal on-scene coordinator in characterizing the 
nature and extent of site-related contamination and impacts. Federal 
Trustees include Commerce, DOI, the Departments of Agriculture, 
Defense, and Energy, and other agencies authorized to manage or 
protect natural resources. 

[24] Under 33 U.S.C. § 2702, the responsible party is liable for the 
removal costs and damages that result from an oil spill and thus will 
be responsible for reimbursing the Fund for these expenses. 

[25] OPA consolidated the liability and compensation provisions of 
four prior federal oil pollution initiatives and their respective 
trust funds into the Oil Spill Liability Trust Fund and authorized the 
collection of revenue and the use of the money, with certain 
limitations, with regards to expenditures. The prior federal laws 
regarding oil pollution included the Federal Water Pollution Control 
Act, the Deepwater Port Act of 1974, the Trans-Alaska Pipeline 
Authorization Act, and the Outer Continental Shelf Lands Act 
Amendments of 1978. Congress created the Fund in 1986 but did not 
authorize collection of revenue or use of the money until it passed 
OPA in 1990. 

[26] The tax expired in December 1994. Besides the barrel tax, the 
Fund also receives revenue in the form of interest on the Fund's 
principal revenues from amounts recovered from responsible parties for 
damages resulting from oil spills, from penalties paid pursuant to the 
Federal Water Pollution Control Act, the Deepwater Port Act of 1974, 
or the Trans-Alaska Pipeline Authorization Act, and from certain other 
sources.

per-barrel tax increases to $0.09. The tax is scheduled to terminate 
at the end of 2017. 

[29] In 2007, we reported that the balance of the Fund was about $600 
million at the end of fiscal year 2006, which at the time, was well 
below its peak of $1.2 billion in 2000. The decline in the Fund's 
balance primarily reflected an expiration of the barrel tax on 
petroleum in 1994. However, the tax was reinstated in 2005 and 
increased to $0.08 per-barrel in 2008; as a result, the Fund is now at 
its highest balance.

and damages that result from an oil spill and thus will be responsible 
for reimbursing the Fund for these expenses.

by the responsible party. 

[37] OPA requires the President, who has delegated responsibility to 
the Coast Guard, through the Secretary of Homeland Security, to issue 
regulations not less often than every 3 years to adjust the limits of 
liability to reflect significant increases in the Consumer Price 
Index. Congress reiterated this requirement in the Coast Guard and 
Maritime Transportation Act of 2006 by requiring that regulations be 
issued 3 years after the enactment of the act (July 11, 2006) and 
every 3 years afterward to adjust the limits of liability to reflect 
significant increases in the Consumer Price Index.

[40] Pub. L. No. 109-241, § 603, 120 Stat. 516, 554. Vessels' 
liability limits were raised again in 2009 by the Coast Guard to 
reflect significant increases in inflation, as required by OPA. 
However, the 2006 adjustment in liability limits, which increased an 
average of 125 percent for the 51 vessels involved in major oil 
spills, were substantially higher than the rise in inflation during 
the period. 

[41] OPA requires that all tank vessels (greater than 5,000 gross 
tons) constructed (or that undergo major conversions) under contracts 
awarded after June 30, 1990, operating in U.S. navigable waters must 
have double hulls. Of the 51 major oil spills, all 24 major spills 
from tank vessels (tankers and tank barges) involved single-hull 
vessels. 

[42] The 15 tank barge spills and the 12 fishing/other vessel spills 
in our review had average costs greater than both the 1990 and 2006 
limits of liability. For example, for tank barges, the average cost of 
$23 million was higher than the average limit of liability of $4.1 
million under the 1990 limits and $10.3 million under the new 2006 
limits.

future. According to NPFC, as of June 2010, claims related to Katrina 
and Rita have been relatively minor.

scenario.
