Highlights of GAO-04-457, a report to congressional committees 

Why GAO Did This Study:

In 1988, radioactive contamination was found in the drinking water 
wells of residences near the federal government’s uranium enrichment 
plant in Paducah, Kentucky. In response, the Department of Energy (DOE) 
began a cleanup program. In 2000, GAO reported that DOE faced 
significant challenges in cleaning up the site and that it was doubtful 
that the cleanup would be completed as scheduled by 2010 and within the 
$1.3 billion cost projection. GAO was asked to determine (1) the amount 
of money DOE has spent on the site, the purposes for which it was 
spent, and the estimated total costs for the site; (2) the status of 
DOE cleanup efforts; and (3) the challenges GAO previously identified 
that continue to be issues for DOE.

What GAO Found:

From fiscal year 1988 through 2003, DOE spent $823 million (in 2002 
dollars) at the Paducah site. Of this total, DOE spent about $372 
million (45 percent) for a host of operations activities, including 
general maintenance and security; $298 million (36 percent) for actions 
to clean up contamination and waste; and $153 million (19 percent) for 
studies to assess the extent of contamination and determine what 
cleanup actions were needed. DOE currently projects that the cleanup 
will take until 2019 and cost almost $1.6 billion to complete—9 years 
and about $300 million more than DOE’s earlier projection. The $1.6 
billion, however, does not include the cost of other DOE activities 
required at the site after the plant ceases operations, including final 
decontamination and decommissioning of the plant and long-term 
environmental monitoring. DOE estimates these activities will cost 
almost $5 billion and bring DOE’s total costs at the site, including 
the $823 million already spent, to over $7 billion through 2070 (in 
2002 dollars). 

DOE has made some progress in cleaning up contamination and waste at 
Paducah, but much of the work remains to be done. For example, while 
DOE has removed about 4,500 tons of scrap metal, almost 50,000 tons of 
contaminated scrap metal remain. Similarly, while DOE’s pilot test of a 
new technology for removing the hazardous chemical trichloroethene 
(TCE) from groundwater at the site had promising results—removing about 
99 percent of the TCE in the test zone—the technology will not be fully 
implemented for more than a year. 

Two of the four challenges GAO identified in 2000—DOE’s plans to use 
untested technology and questionable assumptions that funding for the 
cleanup would increase—no longer pose the impediment to the cleanup 
they once did. Two others—uncertainty over the scope of the cleanup and 
difficulty obtaining timely stakeholder agreement on the cleanup 
approach—are the principal challenges that remain. First, the actual 
scope of the cleanup is not yet known. As a result, any additional 
cleanup actions, the costs of those actions, and the time frame for DOE 
to implement them are also unknown. Second, DOE and the regulators—the 
U.S. Environmental Protection Agency (EPA) and Kentucky—have had 
difficulty agreeing on an overall cleanup approach, as well as on the 
details of specific projects. Over time, these disagreements have 
undermined trust and damaged the parties’ working relationship. After 
involving EPA and Kentucky early in the cleanup planning process, as it 
has done successfully at other sites, DOE officials discontinued this 
approach early in 2001, due in part to concerns about the growing 
cleanup scope, associated costs, and that the planned actions were 
excessive in relation to the risk. The result was an almost 2-year 
dispute that delayed progress. This poor working relationship has also 
prevented the parties from quickly reaching agreement on the technical 
details of specific projects. Unless DOE and the regulators can reach 
and maintain agreement on key aspects of the cleanup and quickly 
resolve technical differences, progress at Paducah could continue to be 
plagued by delays.

What GAO Recommends:

GAO recommends that DOE (1) involve Commonwealth of Kentucky and EPA 
early in the development of both overall cleanup plans and specific 
projects to resolve concerns and reach more timely consensus on cleanup 
decisions and (2) in conjunction with Kentucky and EPA, identify 
external technical peer review groups with environmental cleanup 
expertise to facilitate timely resolution of any future differences. In 
commenting on the report, EPA and Kentucky agreed with the report’s two 
recommendations. DOE provided technical comments, but did not comment 
on our recommendations.

Congressional Committees:

The federal government's uranium enrichment plant at Paducah, Kentucky, 
has a long history of contamination problems. The plant, which enriches 
uranium for commercial nuclear power plants, is located on about 3,500 
acres in western Kentucky and continues to operate under a lease to a 
private company, the United States Enrichment Corporation (USEC). Plant 
operations have contaminated the site over time with radioactive and 
hazardous substances, including technetium-99 (a radioactive fission 
product), polychlorinated biphenyls (PCBs), uranium, and volatile 
organic compounds such as trichloroethene (TCE). In 1988, after 
contaminated groundwater was found in nearby residents' wells, a 
sitewide review identified contaminated surface water and soils within 
and outside the site. As a result, the Department of Energy (DOE) began 
a cleanup program to identify and remove these hazards. DOE's Office of 
Environmental Management has overall responsibility for the site 
cleanup being performed by its contractor, Bechtel Jacobs. Other 
stakeholders include the U.S. Environmental Protection Agency (EPA) and 
the Commonwealth of Kentucky (Kentucky), both of which have regulatory 
responsibilities and participate in cleanup decisions.

In April 2000, prompted by continuing congressional concerns, we 
reported that DOE faced significant challenges in cleaning up the 
Paducah site.[Footnote 1] These challenges included (1) the planned use 
of unproven technologies to treat TCE contamination; (2) assumptions 
that annual federal funding for the cleanup would increase; (3) 
uncertainties about the nature, extent, and sources of the 
contamination to be cleaned up; and (4) optimistic assumptions about 
reaching timely agreement with both EPA and state regulators on issues 
such as cleanup levels, strategies, and priorities that could affect 
DOE's ability to meet its milestones. Given these challenges, we stated 
that it was uncertain that the cleanup could be completed as scheduled 
by 2010 and within the $1.3 billion cost projection, which excluded 
other DOE activities such as the final decommissioning and 
decontamination of the uranium enrichment plant.

As directed by the conference report for DOE's 2003 
appropriations,[Footnote 2] and because of the Committees' ongoing 
concerns regarding the limited progress in cleaning up the site, this 
report discusses (1) the amount of money DOE has spent on the Paducah 
site, the purposes for which the money has been spent, and the 
estimated total costs for the site; (2) the status of DOE efforts to 
clean up the contamination at the site; and (3) those challenges we 
previously identified that continue to be issues for DOE. We provided 
preliminary observations on these issues during our testimony at a 
hearing held in Paducah, Kentucky, on December 6, 2003.[Footnote 3]

In conducting our work, we met with DOE and contractor officials; 
reviewed agency documents involving expenditures, cleanup schedules and 
scope, and cleanup challenges; and visited the Paducah site. We also 
met with and collected information from officials from EPA and 
Kentucky. We conducted our review from April 2003 through March 2004 in 
accordance with generally accepted government auditing standards. Our 
scope and methodology for this review are presented at the end of this 
report.

Results in Brief:

From fiscal year 1988 through fiscal year 2003, DOE has spent $823 
million, in 2002 dollars, on the Paducah site. Of this total, DOE spent 
about $372 million (45 percent) to pay for operations at the site, 
including construction, security, general maintenance, and legal costs; 
$298 million (36 percent) on actions to clean up contamination and 
remove waste; and $153 million (19 percent) for studies to assess the 
extent of the contamination and determine what cleanup actions were 
necessary. Furthermore, although DOE estimated in January 2000 that the 
cleanup would be complete by 2010 and cost about $1.3 billion, DOE now 
estimates that the cleanup will take at least until 2019 and cost 
almost $1.6 billion, due in part to an expanded cleanup scope. That 
estimate, however, does not include the cost of other DOE activities at 
the site, including building and operating a facility to convert more 
than 38,000 cylinders of depleted uranium hexafluoride stored at the 
site to a more stable form, final decontamination and decommissioning 
of the uranium enrichment plant and associated infrastructure after the 
plant ceases operations, and long-term environmental monitoring at the 
site. According to DOE estimates, completing these activities will cost 
almost $5 billion in 2002 dollars. This will bring the total cost of 
DOE activities at the site, including the $823 million already spent, 
to over $7 billion in 2002 dollars through 2070.

DOE has moved forward in cleaning up contamination at Paducah since 
2000, but progress has been slow for several reasons, including lack of 
agreement on the cleanup scope and approach, disagreements on technical 
details of specific cleanup projects, and difficulty resolving 
regulatory violations. As a result, much of the work identified to date 
remains to be done. For example, although DOE has tested a new 
technology for removing the hazardous chemical TCE from groundwater at 
the site with promising results--removing about 99 percent of the TCE 
in the test zone--the technology will not be fully implemented for over 
a year. Similarly, DOE has removed about 4,500 tons of scrap metal, but 
almost 50,000 tons of contaminated scrap metal remain. DOE also plans 
to conduct a number of assessments to determine if other cleanup 
actions, in addition to those already planned, are necessary. For 
example, DOE will test the groundwater near several areas where waste 
is buried to determine if contamination from the waste poses a risk 
above acceptable levels and, if so, what corrective action will be 
needed.

Two of the four challenges we identified in 2000--DOE's plans to use 
untested technology and obtaining adequate funding for the cleanup--no 
longer pose the impediment to the cleanup effort they once did because 
of actions taken to mitigate their impact. The remaining two 
challenges--uncertainty over the scope of the cleanup and obtaining 
timely stakeholder agreement on the cleanup approach--are the principal 
challenges that remain for DOE to resolve in completing the cleanup at 
Paducah.

* Uncertainty about the scope of the cleanup. The entire scope of and 
time frames for the cleanup at the Paducah site are not yet known. 
Although DOE has established completion dates for the cleanup actions 
already identified, additional cleanup actions may be identified as a 
result of both studies that DOE plans to conduct and a comprehensive 
sitewide assessment after the plant ceases operations. However, DOE has 
not yet decided when these additional efforts will begin. As a result, 
any additional needed actions, the costs of those actions, and the time 
frame for DOE to implement them are not yet known. For example, DOE 
plans to initially cover waste currently buried at 12 separate sites 
with soil caps as a waste-management measure. As part of the 
comprehensive sitewide assessment, DOE plans to examine the caps to 
assess their effectiveness in containing the waste. If DOE finds that 
contamination poses a risk above acceptable levels, they may need to be 
excavated, at a cost of about $110 million each. Thus, planning a 
cleanup project whose future costs and scope are unknown poses a 
considerable challenge to DOE.

* Lack of agreement on cleanup approach. DOE and the regulators have 
had difficulty in agreeing on an overall cleanup approach, as well as 
on the details of specific projects. Over time, these disagreements 
have undermined trust and damaged the three parties' working 
relationship. After involving EPA and Kentucky early in the cleanup 
planning process--an approach that has been key to DOE's success at 
other sites, such as at Rocky Flats in Colorado--DOE officials 
discontinued this approach early in 2001 and limited the regulators' 
role to one of reviewing DOE's proposals. This collaborative approach 
was discontinued, due in part to DOE's concerns about the growing 
cleanup scope, the associated increase in costs, and that the planned 
cleanup actions were excessive in relation to the risk to human health 
and the environment. This resulted in an almost 2-year dispute--from 
June 2001 to April 2003--among DOE, EPA, and Kentucky that delayed 
progress. The poor working relationship between DOE and the regulators 
has also prevented them from quickly reaching agreement on the 
technical details of specific projects. For example, it took DOE and 
Kentucky 5 months to agree on the amount and type of data required to 
confirm that contaminated soil from a key drainage ditch could be 
disposed of on-site. Unless DOE and the regulators can reach and 
maintain agreement on key aspects of the cleanup, progress at Paducah 
could continue to be plagued by delays. To facilitate timely agreement 
on the cleanup approach and speedy resolution of differences on 
technical issues to help prevent future delays, this report recommends 
that DOE involve the regulators early in the cleanup planning process, 
and that the three parties identify and retain external technical peer 
review groups with environmental cleanup expertise.

Background:

The Paducah uranium enrichment plant, shown in figure 1, is located in 
western Kentucky, just south of the Ohio River and about 10 miles west 
of the city of Paducah. The plant--formerly operated by DOE and now 
operated by USEC--enriches uranium for commercial nuclear power 
reactors. Since it began operations in 1952, the Paducah plant has 
processed, or enriched, more than a million tons of uranium.

Plant:

[End of figure]

Plant operations over time have introduced to the site radioactive and 
hazardous chemical wastes, including technetium-99, PCBs, uranium, and 
volatile organic compounds such as TCE. In past years, a cleaning 
solvent containing TCE--much like that previously used by dry cleaners-
-was used to degrease parts and equipment. In the plant's more than 
half a century of operations, these various waste materials have 
contaminated the area's groundwater, surface water, soils, and air.

The Paducah site cleanup is funded primarily through the Uranium 
Enrichment Decontamination and Decommissioning Fund, which was 
established by the Energy Policy Act of 1992.[Footnote 4] The fund 
receives money from both annual federal appropriations and assessments 
on commercial utilities. Through fiscal year 2003, the Paducah site had 
received from the fund annual cleanup amounts ranging from $35.9 
million to $97.2 million.

The Comprehensive Environmental Response, Compensation, and Liability 
Act of 1980, as amended (CERCLA), governs the cleanup of sites placed 
on the National Priorities List--EPA's list of contaminated sites 
designated as highest priority for cleanup. Paducah was placed on the 
list in 1994. CERCLA provides broad federal authority to respond 
directly to releases or threatened releases of hazardous substances 
that may endanger public health or the environment. It stresses the 
importance of permanent cleanup remedies and innovative treatment 
technologies, and it encourages citizen participation in deciding on 
how sites should be cleaned up. The Resource Conservation and Recovery 
Act of 1976, as amended, also comes into play in governing the Paducah 
cleanup. While CERCLA generally deals with cleaning up inactive and 
abandoned hazardous waste sites, this act generally governs the safe 
management and disposal of the huge amounts of hazardous or other solid 
wastes that are generated nationwide and are currently destined for 
disposal or recycling. The act permits states, rather than EPA, to 
assume primary responsibility for implementing its requirements.

At Paducah, the key documents governing the cleanup are a federal 
facility agreement, the site management plan, and the life cycle 
baseline. The federal facility agreement--among DOE, EPA, and Kentucky-
-coordinates the requirements of both CERCLA and the Resource 
Conservation and Recovery Act for cleanup activities at Paducah and 
governs the cleanup. Under this agreement, the parties developed a site 
management plan that lays out DOE's approach for the cleanup and 
includes near-and long-term milestones and projected activities for the 
site. This plan is updated annually by DOE and approved by EPA and 
Kentucky. DOE also uses a life cycle baseline to manage the cleanup. 
The life cycle baseline contains detailed information on cleanup 
projects, cost estimates, and time frames for completion and is updated 
frequently by DOE's contractor to reflect the evolving nature of the 
cleanup process. For this report, we examined the May 2003 and November 
2003 versions of the site management plan and the September 2002 
version of the life cycle baseline.

DOE's Office of Environmental Management is responsible for the cleanup 
at Paducah, including characterizing, treating, and disposing of waste 
and contamination identified during site cleanup. Prior to January 
2001, the Office of Nuclear Energy acted as the "landlord" at the site 
with responsibilities for maintaining roads, grounds, facilities not 
leased to USEC, and DOE material storage areas (DMSAs), which have 
since been transferred to the Office of Environmental Management. 
Currently, the role of the Office of Nuclear Energy is limited to 
administering USEC's lease.

DOE's cleanup strategy for the Paducah site divides the cleanup into 
seven major categories as follows:

* Groundwater--About 10 billion gallons of groundwater are contaminated 
with radioactive and hazardous materials.

* Surface water--Contaminated sediments have been discovered in ditches 
and creeks leaving the site. One of the main sources of this 
contamination is rain runoff from thousands of tons of contaminated 
scrap metal stored at the site.

* Surface soils--Soils and sediments at the site have been contaminated 
by water runoff, spills, and buried waste.

* Legacy waste--Low-level radioactive or hazardous waste generated at 
the site before 2001 from DOE cleanup or site maintenance activities 
remains stored at the site.

* DOE material storage areas--160 indoor and outdoor storage areas 
contain a variety of radioactive, hazardous, and other materials. These 
areas have been added to the cleanup scope since our 2000 report.

* Burial grounds--Twelve burial grounds contain a variety of waste, 
including barrels of materials with low levels of radioactivity and 
hazardous chemicals.

* Decontamination and decommissioning of 17 unused buildings and other 
structures--These facilities were contaminated during earlier 
operations; 15 have been added to the cleanup scope since our 2000 
report.

DOE's draft fiscal year 2004 site management plan, submitted to the 
regulators for approval in November of 2003, would commit DOE, EPA, and 
Kentucky to an accelerated cleanup of the site. Specifically, the plan 
establishes a two-phased cleanup approach for five of the seven 
categories--DMSAs and legacy waste are not included but are covered 
under DOE's life cycle baseline and an October 2003 settlement between 
DOE and Kentucky.[Footnote 5] The two-phase approach consists of a 
series of early cleanup actions and studies while the uranium 
enrichment plant is in operation and a second series of actions to be 
implemented after the plant ceases operations. The primary objectives 
of the first phase are to prevent on-and off-site human exposure--
including exposure of plant workers--to unacceptable risks, and to 
complete cleanup actions that provide the greatest opportunity for 
reducing risks. The second phase will include final decontamination and 
decommissioning of the plant and associated infrastructure,[Footnote 6] 
and an evaluation of the entire site to (1) determine the effectiveness 
of cleanup actions taken in phase I; (2) assess residual risks; and (3) 
determine what, if any, additional cleanup actions are needed.

DOE Has Spent $823 Million at the Paducah Site; However, Billions of 
Dollars Will Be Required to Complete DOE Activities at the Site:

From fiscal year 1988 through fiscal year 2003, DOE has spent $823 
million (in 2002 dollars) for cleanup and related activities at 
Paducah. DOE's expenditures fall into three major categories: (1) base 
operations--including activities to maintain the site, such as 
security, waste storage, and environmental monitoring, and some 
administrative and legal costs; (2) removal and remedial actions--
activities such as treatment and disposal of waste, and projects to 
clean up contamination at the site; and (3) assessments--studies done 
to investigate and characterize, or determine the qualities of, 
contamination and waste so that DOE's contractor can determine what 
remedial or removal actions are necessary. As figure 2 shows, 45 
percent was spent on base operations, 36 percent on actions taken to 
clean up contamination and remove waste, and 19 percent on assessments.

Figure 2: Expenditures at Paducah by Category, Fiscal Years 1988-2003:

[See PDF for image]

Note: Total cleanup expenditures for fiscal years 1988-2003, adjusted 
to fiscal year 2002 dollars, were $823 million. The individual dollar 
figures noted above do not total $823 million because of rounding.

[End of figure]

However, for the past three fiscal years, the percentage of 
expenditures on remedial and removal actions has increased to about 
half of all funds expended. This increase can be attributed to 
increased overall funding for the cleanup and a smaller percentage of 
funds being spent on assessments. Nevertheless, the percentages spent 
on cleanup and related activities at Paducah through fiscal year 2003 
are similar to those DOE's Office of Environmental Management found for 
all of its cleanup programs: only about one-third of the environmental 
management program budget goes toward actual cleanup and risk reduction 
work, with the remainder going to maintenance, fixed costs, and 
miscellaneous activities, contributing to a lack of risk reduction and 
raising costs for DOE's cleanups.[Footnote 7] As a result, DOE has 
since begun to implement accelerated cleanup plans at Paducah and other 
sites.

DOE's current estimate for completing the cleanup at Paducah is almost 
$1.6 billion--a $300 million increase over its 2000 estimate--and the 
completion date has moved from 2010 to 2019.[Footnote 8] The cost 
increase is due in part to an expanded project scope since 2000--for 
example, the inclusion of DMSAs not previously considered part of the 
cleanup--as well as millions of dollars for site operations for each of 
the nine additional years of cleanup. However, according to DOE's site 
manager, DOE has not yet revised its life cycle baseline to reflect the 
scope changes under the proposed accelerated cleanup approach and DOE 
may be able to reduce the cost of the cleanup.[Footnote 9] For example, 
DOE's life cycle baseline currently includes the cost of excavating 
five burial grounds at a cost of about $550 million, but DOE's draft 
site management plan calls only for capping the burial grounds unless 
further study indicates that the contamination from the burial grounds 
poses a risk above acceptable levels.

However, the $1.6 billion cleanup estimate does not represent DOE's 
total responsibilities at the site. In addition to cleaning up the 
contamination from past activities at the site, DOE will (1) build and 
operate a facility to convert more than 38,000 cylinders of depleted 
uranium hexafluoride stored at the site to a more stable form;[Footnote 
10] (2) carry out final decontamination and decommissioning of the 
uranium enrichment plant and associated infrastructure once USEC ceases 
plant operations; and (3) perform long-term environmental monitoring at 
the site, which includes activities such as monitoring groundwater and 
surface water for residual contamination. According to DOE estimates, 
completing these activities will cost almost $5 billion in 2002 
dollars. This will bring the total cost of DOE activities at the site, 
including remaining cleanup costs and the $823 million already spent, 
to over $7 billion, in 2002 dollars.[Footnote 11] Table 1 shows DOE's 
past expenditures and estimated costs and time frames for future 
activities at the site.

Sources: DOE and GAO.

Note: For years prior to 2003, we used the actual gross domestic 
product price index from the Bureau of Economic Analysis, Department of 
Commerce, to convert the estimated costs to 2002 dollars. Otherwise, we 
used DOE's escalation cost of 2.5 percent as the inflation rate to 
convert the estimated cost from current dollars to 2003 dollars and 
subsequently converted the resulting cost in 2003 dollars to an amount 
in 2002 dollars using the bureau's actual gross domestic product price 
index.

[A] DOE's estimate of decontamination and decommissioning costs, which 
was issued in October 2000, assumed that uranium production activities 
at Paducah would terminate in fiscal year 2007, and final 
decontamination and decommissioning would occur from fiscal year 2010 
to fiscal year 2021. However, DOE has not yet established a schedule 
for final decontamination and decommissioning at Paducah. DOE's 
estimate includes a 20 percent contingency. In addition to the costs in 
DOE's 2000 estimate, this figure includes the cost of constructing an 
on-site waste disposal cell and remediation of underlying soil and 
foundations. It does not include decontamination and decommissioning of 
2 structures included in the 2000 estimate because these are now 
included in phase I of the cleanup.

[B] Construction of the conversion facility is scheduled to begin 
during fiscal year 2004.

While DOE Has Achieved Some Progress, Much Remains to Be Done:

Since 2000, DOE has made some progress in cleaning up the contamination 
and waste at Paducah, but much of the cleanup work remains to be done. 
Cleanup progress has been slowed by several factors, including several 
disagreements over the scope and approach of the cleanup and technical 
details of specific cleanup projects, and difficulty resolving 
regulatory violations at the site. For example, an on-site landfill was 
unavailable for almost a year--from November 2002 to October 2003--as a 
result of a violation notice that Kentucky issued to DOE for improper 
waste disposal at the landfill. Until DOE and Kentucky resolved the 
violation, 25 cleanup projects involving 19,056 tons of various types 
of waste were delayed.[Footnote 12] A discussion of the cleanup 
categories, including DOE's major accomplishments since our 2000 report 
(as of the end of fiscal year 2003) and the work remaining, 
follows.[Footnote 13]

Groundwater:

After hazardous and radioactive contamination was found in the drinking 
water wells of residences near the Paducah plant in 1988, DOE 
discovered that plumes of groundwater contaminated with TCE and 
technetium-99 were moving toward the Ohio River.[Footnote 14] The 
largest identified source of the contamination is below the plant's C-
400 building, where TCE had been used for years to degrease parts and 
equipment. DOE's strategy for addressing the groundwater contamination 
is to focus its resources on this and other large concentrations of 
accumulated TCE at the Paducah site.

To address the source contamination, DOE conducted a pilot test of 
technology to remove TCE sources from the ground. According to DOE 
officials, the test results were promising. During the pilot test, 
about 1,500 gallons of TCE were removed from the largest source--about 
99 percent of the TCE in the area treated. However, this represents 
only about 1 percent of the estimated 180,000 gallons of TCE that had 
leaked into the ground at the site.[Footnote 15] DOE contractor 
officials told us that full implementation of this technology at C-400 
will not occur until 2006, after the regulators have approved DOE's 
proposal and DOE has completed the system design.In spring 2004, DOE 
will conduct a study to investigate the second largest TCE source at 
the site and determine what additional actions are necessary. In 
addition to its actions to address major TCE sources, DOE has pumped 
from the ground and treated about 710 million gallons of groundwater 
from the contaminated groundwater plumes since our 2000 report to 
remove TCE and technetium-99 and prevent off-site contamination. About 
1.3 billion gallons have been treated this way since the program began. 
DOE's estimated completion date for currently planned groundwater 
cleanup activities is 2010. While this end date takes into account 
construction and implementation of a system to remove contamination, 
treatment actions could extend well beyond that date.

Surface Water:

DOE discovered surface water contamination in creeks, ditches, and 
sludge lagoons--artificial ponds for the storage of wastewater. 
Historically, storm water runoff and wastewater from plant operations 
have been discharged into two streams flanking the plant--Bayou Creek 
and Little Bayou Creek--through a series of ditches. Each discharge 
point is monitored to ensure that the waste material entering the 
stream is within the parameters of the discharge permit issued by 
Kentucky. Contaminants of concern are technetium-99, solid uranium 
tetraflouride, uranium-contaminated silts and sediments, 
radionuclides, metals, and PCBs.

To prevent contaminated runoff, DOE has removed about 4,500 tons of 
scrap metal from the site since 2000--primarily crushed drums that 
previously had contained uranium, and aluminum ingots. An estimated 
almost 50,000 tons of contaminated scrap metal remains to be removed 
from the site. At the north-south diversion ditch, a key wastewater 
conduit from the plant, surface water discharges and runoff have been 
rerouted and piped to bypass contaminated areas, and DOE has begun 
excavation work to remove contaminated soil. According to DOE 
officials, DOE has excavated section 2 of the ditch and plans to 
complete excavation of section 1 by summer 2004--a year ahead of 
schedule. DOE will also conduct additional investigations and risk 
assessments to determine what additional actions are required to 
address contamination associated with internal ditches; outfalls--
outlets through which water leaves the site; sections 3, 4, and 5 of 
the north-south diversion ditch; and the storm sewer system, and 
whether additional sediment controls are needed. The estimated 
completion date for all currently planned surface water cleanup 
activities is 2017.

Surface Soils:

Because soil contamination represents a lower risk for exposure and 
migration than, for example, groundwater contamination, and because 
other work, such as removal of scrap metal, must be performed before 
some soils can be reached for assessment and removal, surface soils 
have been a lower priority than other cleanup categories. However, DOE 
has performed a preliminary assessment of all accessible surface soils 
at the site to identify radioactive contamination and protect plant 
workers and has removed 2,500 cubic yards of contaminated soils--enough 
to cover a football field 17 inches deep. DOE estimates that it will 
need to remove and dispose of an additional 87,500 cubic yards of soils 
by 2015. In addition, other contaminated areas that are not currently 
accessible because they are still in use by USEC, as well as the soil 
under the 17 buildings and other structures being decontaminated and 
decommissioned during phase I of the cleanup, will be addressed after 
the plant ceases operations during phase II.

Legacy Waste:

We reported in 2000 that the equivalent of 52,000 55-gallon barrels of 
waste was stored in various locations on the Paducah site. Most of this 
waste is materials that have a low level of radioactivity. All of this 
waste has undergone an initial characterization to determine proper on-
site storage and may require additional characterization to determine 
proper treatment, if necessary, and disposal. Since 2000, DOE has 
disposed of the equivalent of over 7,000 barrels off-site and has 
repackaged another 6,000 barrels' worth of waste that is ready for 
disposal. DOE plans to remove the 6,000 barrels ready for disposal and 
characterize and dispose of the remaining legacy waste--the equivalent 
of over 38,000 barrels--by 2011. In addition to the legacy waste, new 
waste generated during the course of the cleanup must be disposed of 
within a year of its generation.

DOE Material Storage Areas:

In 2000, we reported that DMSAs were not included in the scope of the 
Office of Environmental Management's cleanup plan. These storage areas 
were created in 1996 when DOE accepted responsibility for large amounts 
of material stored in USEC-leased buildings and outdoor areas to 
expedite the process USEC used to obtain an operating certificate. The 
materials in the 160 DMSAs include thousands of barrels of low-level 
radioactive waste and PCB wastes, barrels labeled as asbestos waste, 
contaminated uranium processing equipment, various items and containers 
whose contents are unknown, and scrap metal.

Since our 2000 report, DOE has transferred responsibility for DMSAs 
from the Office of Nuclear Energy to the Office of Environmental 
Management so that they can be addressed as part of the comprehensive 
sitewide cleanup scope. DOE has also ranked the 160 DMSAs at the 
Paducah site on the basis of their potential to contain hazardous 
materials or contaminate the environment: 34 are high-priority, 11 are 
medium-priority, and 115 are low-priority. Of the 160 DMSAs, DOE has 
completely characterized materials from 28 high-and 10 low-priority 
DMSAs and has initiated characterization of an additional 41 DMSAs. As 
a result, two-thirds of the total volume of materials in all 160 DMSAs 
has been characterized as of March 2004. According to DOE officials, 
only 0.01 percent of the materials characterized to date have been 
determined to be hazardous waste. In addition to the progress made in 
characterizing DMSAs, all materials from 9 high-priority DMSAs--about 
15 percent of all materials to be removed during phase I of the 
cleanup--have been removed and either shipped off-site or placed in an 
on-site landfill for final disposal. DOE plans to complete its 
characterization of the DMSAs by the end of fiscal year 2009 and 
dispose of all free-standing materials from the remaining DMSAs by 
2010. Fixed equipment in the DMSAs, such as piping and equipment 
attached to buildings and facilities, will be disposed of during final 
decommissioning and decontamination of the site after the uranium 
enrichment plant ceases operations.[Footnote 16]

Burial Grounds:

The 12 burial grounds at the site contain a variety of waste, including 
barrels of materials with low levels of radioactivity and/or hazardous 
chemicals, and pyrophoric uranium, which has a tendency to 
spontaneously combust in the presence of oxygen. To date, DOE's 
activities at the 12 burial grounds have consisted of studies and 
environmental monitoring and maintenance, and DOE continues to conduct 
these studies. Currently, DOE's planning assumption is that they will 
cap--cover with a layer of soil--the burial grounds and monitor nearby 
groundwater for contamination to evaluate the effectiveness of the 
caps. If contamination from the burial grounds is found to pose a risk 
above acceptable levels, some burial grounds may need to be excavated 
during phase II of the cleanup at the site, which is not scheduled to 
start until after the plant ceases operations. Groundwater monitoring 
will be ongoing through the end of phase I of the cleanup in 2019.

Decontamination and Decommissioning of 17 Unused Buildings and Other 
Structures:

Seventeen buildings and other structures that were originally used as 
part of the uranium enrichment process, including two 250,000-gallon 
water storage tanks, a nitrogen generation plant, and an incinerator 
previously used for disposing of contaminated items are no longer in 
use and await decontamination and removal. In 2000, we reported that 
only 2 of 18 unused buildings and structures awaiting decontamination 
and decommissioning at the site were included in the scope of the 
Office of Environmental Management's cleanup plan. Since then, 1 of the 
18 buildings has been transferred to USEC for use in operations at the 
Paducah Gaseous Diffusion Plant, according to DOE contractor officials; 
the remaining 17 are now included in the scope of the Office of 
Environmental Management's cleanup. DOE has completed its preliminary 
assessment of the contamination at the 17 buildings and other 
structures and has begun removing the infrastructure of one of the 
buildings. In addition, DOE continues to perform surveillance and 
maintenance on all 17 inactive facilities to prevent significant 
deterioration of the buildings and other structures until 
decommissioning and decontamination is complete. DOE's plan proposes to 
demolish all of these inactive facilities by 2017; the underlying 
foundations and soil will be addressed during phase II of the cleanup.

While Two Previously Identified Challenges Have Been Mitigated, 
Uncertainty about the Cleanup Scope and Reaching Stakeholder Agreement 
on Cleanup Approach Remain the Current Principal Challenges:

Two of the four challenges we identified in 2000--DOE's plans to use 
untested technology and obtaining adequate funding for the cleanup--no 
longer pose the impediment to the cleanup effort they once did because 
of actions taken to mitigate their impact. The remaining two 
challenges--uncertainty over the scope of the cleanup and obtaining 
stakeholder agreement on the cleanup approach--are the principal 
challenges that remain for DOE to resolve to successfully complete the 
cleanup at Paducah.

DOE Has Mitigated the Impact of Two Previously Identified Challenges:

In 2000, we reported some of the cleanup technologies contemplated, 
while not new, were untested for the specific environment in which they 
were to be applied. Since then, several technologies have been 
evaluated for treating groundwater for TCE contamination at Paducah, 
including permeable treatment barriers and six-phase heating.[Footnote 
17] According to DOE officials, removing TCE is the most difficult 
cleanup task at Paducah.[Footnote 18] Specifically, TCE is difficult to 
treat when it has mixed with groundwater and soil--it migrates to the 
bottom of the aquifer making it difficult to access, and because it 
dissolves slowly in water, it can contaminate large quantities of 
groundwater for long periods of time. Permeable treatment barriers, 
which DOE assumed in 2000 would be the primary treatment strategy for 
addressing contaminated groundwater, could not be effectively installed 
at Paducah, according to DOE officials, because of unfavorable soil 
conditions and potential high costs to maintain the technology. 
Furthermore, such technologies only deal with the contaminated 
groundwater plume, not the source of the contamination. However, DOE 
has made progress in testing six-phase heating for removing TCE from 
the groundwater and soil at Paducah. In the six-phase heating process, 
electricity is applied to steel rods that have been drilled into the 
ground to heat the soil. When the soil is hot enough that the TCE and 
groundwater begin to boil, the resulting vapor is collected and 
condensed and then filtered to remove the TCE. DOE officials told us 
the results of the test exceeded their expectations, and their 
preliminary review of the test results concluded that the technology 
should be considered for full-scale implementation. DOE officials state 
that they have submitted a proposed plan to the regulators for approval 
and plan to begin full-scale implementation in 2006. The officials 
added that unless problems are encountered when the process is fully 
implemented, DOE should be able to remove the majority of the TCE 
source.

In 2000, we also reported that assumptions about future increases in 
federal funding for the Paducah cleanup could affect DOE's ability to 
meet cleanup milestones and that, if the planned increases did not 
occur, the cleanup could be delayed and costs could increase. DOE had 
estimated that, as the cleanup progressed, its funding would increase 
from $78 million in fiscal year 2001 to $307 million in fiscal year 
2008. We now believe these assumptions were unrealistic considering 
that funding levels for the cleanup during the seven fiscal years prior 
to 2001 averaged only $43 million annually. Since 2000, DOE has revised 
its annual funding assumptions to reflect more consistent and 
appropriate funding levels. Currently, DOE estimates its annual funding 
needs at about $100 million.[Footnote 19] DOE's contractor official for 
finance stated that annual funding of $100 million is sufficient to 
complete the cleanup given the scope of work and the 2019 end date 
proposed in its fiscal year 2004 draft site management plan. In 
addition, actual annual funding for the Paducah cleanup has increased 
significantly in recent years. In fact, in fiscal year 2003, Congress 
appropriated more than DOE's $100 million request. However, if cleanup 
cost estimates increase, or appropriations for the cleanup are not 
maintained at their current level, funding could resurface as a 
challenge.

Uncertainty Regarding the Scope of DOE's Cleanup Remains a Challenge:

In 2000, we also reported that uncertainties about the contamination 
yet to be cleaned up could result in increased cleanup costs. These 
uncertainties remain a challenge, in part, for DOE because its fiscal 
year 2004 draft site management plan does not clearly define the entire 
scope and time frame for completing the cleanup. For phase I of the 
cleanup, DOE has identified a series of early actions for five of the 
seven cleanup categories. Some of these actions are currently under 
way, and DOE plans to have them all completed by 2019. DOE plans to 
study the effectiveness of phase I actions as they are completed. Phase 
II of the cleanup will include the final decontamination and 
decommissioning of the USEC plant and a comprehensive sitewide 
assessment that will evaluate the effectiveness of all cleanup actions 
conducted in phase I and assess the need for additional cleanup 
actions. For example, DOE's planning assumption is to cover the 12 
burial grounds with soil caps during phase I as a waste management 
measure and then monitor the burial grounds to assess the effectiveness 
of the caps in containing the waste. If DOE finds that contamination 
from these sites poses an unacceptable risk, DOE may need to excavate 
some of the burial grounds, at a cost of about $110 million each, 
during phase II. Additionally, since DOE does not plan to remove the 
foundations and soil underlying the 17 unused buildings and other 
structures to be decontaminated and decommissioned during phase I, 
additional cleanup actions may be necessary during phase II if the soil 
is found to be contaminated.

DOE has also not yet determined when phase II will begin. DOE's draft 
site management plan calls for phase II to begin once the USEC plant 
ceases operations. USEC has recently announced that the plant will 
operate until about 2010.[Footnote 20] However, DOE's site manager 
stated that several options exist. For example, rather than begin phase 
II in 2010, DOE could decide to postpone the comprehensive sitewide 
assessment and some phase II cleanup actions until DOE has completed 
all of phase I. Alternatively, DOE could decide to start final 
decontamination and decommissioning shortly after the plant ceases 
operations in approximately 2010 and conduct phase II activities 
concurrently with phase I cleanup actions. If DOE selects this option, 
increases in annual funding would be needed to conduct both phases of 
the cleanup simultaneously. Until DOE decides when phase II will begin, 
any additional necessary actions, the costs of those actions, and the 
time frame for DOE to implement them are not known.

DOE, Kentucky, and EPA Have Continued to Have Great Difficulty Agreeing 
on a Cleanup Approach:

In our 2000 report, we stated that DOE's assumptions about the timely 
achievement of regulatory and stakeholder agreement on cleanup levels, 
strategies, and priorities were optimistic because the regulators had 
already disagreed with some of DOE's proposed approaches and had not 
reached agreement on several contentious issues. Since then, DOE and 
the regulators have continued to have difficulty agreeing on an overall 
cleanup approach and individual projects. As table 2 shows, the draft 
fiscal year 2004 site management plan is only the latest of several 
cleanup plans proposed for the site since 1999, all of which have 
differed significantly in terms of costs, scope, and time frames for 
cleanup and were intended as solutions to problems at the site. 
According to DOE's site manager, DOE has revised its plans for Paducah 
to incorporate additional scope and ensure that the requirements of the 
two statutes that govern the cleanup were met. On the other hand, EPA 
and Kentucky officials told us that these frequent changes have 
frustrated them and undermined their confidence that DOE would adhere 
to an agreed-to plan and achieve progress in cleaning up the site. As a 
result, their working relationship has deteriorated, slowing cleanup 
progress.

[End of table]

The most significant example of the parties' inability to reach and 
maintain agreement has been a dispute over the fiscal year 2001 site 
management plan that lasted from June 2001 to April 2003 and slowed 
overall cleanup progress. The dispute began when DOE headquarters 
decided they could no longer support the site management plan 
assumptions. According to Kentucky officials, this site management plan 
was developed collaboratively by high-level officials from DOE, EPA, 
and Kentucky who agreed on an overall cleanup approach. In addition, a 
midlevel working group was developed, called the Core Team, with 
representatives from DOE, EPA, and Kentucky who examined the technical 
requirements to plan individual projects. These two groups identified a 
number of cleanup actions for implementation, and the parties 
successfully agreed on the fiscal year 2001 site management plan. 
However, as a result of the increased cleanup scope identified by the 
Core Team, the resulting increase in costs, and DOE's Top-to-Bottom 
Review,[Footnote 21] DOE headquarters questioned whether the planned 
cleanup actions were excessive in relation to the risk to human health 
and the environment and requested additional time from the regulators 
to further review the site management plan. The regulators denied the 
request. Because of its continuing concerns that the planned cleanup 
actions were excessive, DOE subsequently discontinued this 
collaborative approach, removed decision-making authority from the Core 
Team, and reduced the regulators' role to reviewing DOE's proposals. 
According to Kentucky officials, DOE also limited communication between 
DOE technical staff and the regulators.

While DOE and Kentucky have made some progress in addressing near-term 
cleanup impediments, the three parties continue to have difficulty in 
reaching agreement on the overall approach. DOE and Kentucky signed a 
letter of intent in August 2003, followed in October 2003 by an agreed 
order that resolved all outstanding Kentucky environmental compliance 
violations pending against the department. The letter of intent also 
commits the two parties to promote an accelerated cleanup of the site, 
which is reflected in the draft fiscal year 2004 site management plan. 
Nevertheless, according to DOE's site manager, DOE and the regulators 
are still negotiating the fiscal year 2004 site management plan, 
submitted by DOE on November 15, 2003. In February 2004, DOE received 
and responded to formal comments from EPA and Kentucky, and submitted a 
second draft of the site management plan to the regulators for review. 
It is uncertain when the 2004 site management plan, which was to be 
implemented during fiscal year 2004, will be finalized. Furthermore, as 
discussed earlier, many more decisions about the cleanup's scope and 
DOE's approach will require agreement by the three parties throughout 
the life of DOE's cleanup efforts. Early involvement by all three 
parties could be helpful in avoiding similar lengthy and unproductive 
cycles of negotiations over the annual site management plans in the 
future.

Involving the regulators early in planning the overall cleanup approach 
and specific projects has been a key element of DOE's good working 
relationship with regulators at other DOE sites. For example, at Rocky 
Flats in Colorado, DOE involves the regulators when updating the site 
management plan and developing individual projects. This allows 
concerns to be communicated and addressed early in the process. 
According to officials at Colorado's Department of Public Health and 
Environment, this has reduced the amount of time needed for regulatory 
reviews, since the number of "comment and revise, comment and revise" 
cycles has been reduced. Colorado state officials also told us that a 
successful working relationship requires up front and continual 
communication beyond just reviewing already developed documents and 
proposals. Additionally, they stated that a consultative process is an 
evolving process and must be worked through in good faith by all 
parties.

Both EPA and Kentucky officials believe that their early involvement 
would aid cleanup progress at Paducah, such as early involvement in 
developing the annually submitted site management plan. EPA and 
Kentucky officials told us that they have been frustrated by their 
exclusion from the planning process for both the overall cleanup 
approach and specific projects and feel that the current process is 
more time-consuming than if they were involved early in the process. 
Not being involved in the planning process reduces their role to 
reviewing DOE's project proposals and making comments on those 
proposals. Comments on proposals often necessitate more than one 
revision cycle. Multiple revisions can cause schedule changes and 
delays because DOE's schedule for each project assumes only one 
revision to respond to regulators' comments. At a December 6, 2003, 
hearing before the Senate Committee on Energy and Natural Resources in 
Paducah, the Secretary of Kentucky's Natural Resources and 
Environmental Protection agency encouraged all parties to revisit the 
Core Team approach. He urged that a collaborative team be created and 
empowered to work effectively toward meaningful action. However, DOE's 
site manager cautioned that such an approach would not necessarily 
hasten decision making, but agreed that early discussion of technical 
details could possibly help improve formal submission of DOE cleanup 
proposals to the regulators.

The poor working relationship between DOE and the regulators has also 
prevented them from quickly reaching agreement on technical details of 
specific projects. According to Kentucky officials, DOE proposed using 
existing data about the north-south diversion ditch--a major wastewater 
conduit from the plant--to determine whether soil from the ditch could 
be disposed of in an on-site landfill. However, Kentucky's response to 
DOE's proposal was that these data were not sufficient because the 
samples were not representative of all the areas where waste entered 
the ditch. It took DOE and Kentucky 5 months to agree on a sampling 
plan. Similarly, DOE and Kentucky disagreed over whether available data 
demonstrated that the risk reduction to be obtained by installing 
sedimentation basins was significant enough to warrant their 
installation. In 2000, DOE planned to install two sedimentation basins 
at a cost of $4 million each, but the state wanted four basins. 
Currently, DOE's position is that it does not believe that available 
data indicates any sedimentation basins are needed, but has agreed to 
collect additional data and install basins if new information warrants 
it. DOE and Kentucky are still negotiating the amount and type of data 
required to determine whether the basins are needed.

As the cleanup progresses and individual projects are designed and 
implemented, DOE and the regulators will continue to have to reach 
agreement on the specifics of these projects. Given the past technical 
disagreements and the vast scope of work remaining at Paducah, 
additional technical issues such as those experienced with the north-
south diversion ditch and the sedimentation basins are likely to arise 
in the future. However, DOE and the regulators do not currently use any 
mechanisms such as external technical peer reviews to assist them in 
resolving technical disputes in a timely manner. A 1997 National 
Academy of Sciences report on the use of peer review by DOE's Office of 
Science and Technology cited several benefits of using such reviews to 
help resolve technical disagreements that could apply to 
Paducah.[Footnote 22] According to the report, peer reviews:

* provide an effective way to increase the technical quality of 
projects, thereby enhancing the credibility of project decisions;

* add confidence that those decisions are based on the best scientific 
and technical information available; and:

* introduce independent experts to a project who can recognize 
previously unrecognized technical strengths and weaknesses, challenge 
the status quo, and identify ways to improve the project that may have 
been overlooked.

DOE and EPA officials told us that they believe the use of peer reviews 
could help resolve technical disagreements at the site. Kentucky 
officials told us that while they believe such reviews have value, they 
would not want the results of a review to usurp the state's regulatory 
decision-making authority.

Conclusions:

While some progress has been made in cleaning up the site and 
addressing previously identified challenges, DOE still faces 
significant challenges in completing the cleanup at Paducah. For 
example, DOE, EPA, and Kentucky have been unable to agree on an overall 
cleanup approach and technical aspects of individual projects. Even 
now, DOE and the regulators are still negotiating the draft fiscal year 
2004 site management plan, submitted by DOE in early November 2003, and 
it is uncertain when it will be finalized. Moreover, despite past 
difficulties, which have slowed cleanup progress, and the many 
decisions that must be made in the future regarding scope and time 
frames, the parties have no mechanisms in place, such as early 
stakeholder involvement or technical peer review, to help resolve 
disagreements between the three parties in a timely manner. Unless DOE 
and the regulators can reach and maintain agreement on key aspects of 
the cleanup and quickly resolve technical disagreements, progress at 
Paducah could continue to be hampered by delays.

Recommendations for Executive Action:

To help improve the likelihood that DOE and the regulators will reach 
timely agreement on the cleanup approach, we recommend that the 
Secretary of Energy direct the Assistant Secretary of the Office of 
Environmental Management to:

* involve the Commonwealth of Kentucky and EPA early in the development 
of the annual site management plan and specific projects--before 
submitting formal cleanup proposals for regulatory approval--so that 
the parties can identify and resolve their concerns and reach consensus 
on cleanup decisions in a more timely manner, and:

* in conjunction with Kentucky and EPA, identify and retain external 
technical peer review groups with environmental cleanup expertise to 
facilitate timely resolution of any future differences between DOE and 
the regulators.

Agency Comments and Our Evaluation:

We provided DOE, EPA, and Kentucky with draft copies of this report for 
their review and comment. DOE's written comments on our report did not 
address our recommendations, but DOE agreed that it still faces many 
challenges in accomplishing a safe, cost-effective cleanup at the 
Paducah site. However, DOE disagreed with our characterization of the 
department's decision to discontinue the Core Team process and stated 
that we did not fully acknowledge DOE's improving working relationship 
with the regulators. DOE also asserted that our report did not provide 
a balanced presentation of all three parties' responsibilities for the 
past poor working relationship and delayed progress. Finally, DOE 
stated that our report did not adequately represent recent progress at 
the site and that we should not include post-closure environmental 
monitoring costs in comparison of past cleanup costs or estimates.

We disagree with DOE's view that we did not accurately characterize 
their decision to discontinue the Core Team approach. Our report 
clearly cites DOE's rationale for discontinuing its participation. We 
also disagree that we did not fully acknowledge the progress DOE and 
Kentucky have made in improving their working relationship. For 
example, our report does reflect the progress they have made in 
addressing near-term clean up impediments, such as the signing of the 
agreed order that resolved outstanding regulatory violations. However, 
the inability of the three parties to agree to and sign the fiscal year 
2004 Site Management Plan, issued in draft in November 2003, indicates 
that the parties' working relationship continues to be a challenge. We 
also disagree with DOE's statement that our report does not provide a 
balanced presentation of all three parties' responsibilities for the 
past poor working relationship and delayed progress. We cite throughout 
our report examples of disagreements between DOE and the regulators, 
providing each side's position on these issues. For example, we 
describe the disagreement over a sampling plan for soil excavation at 
the north-south diversion ditch, and present DOE and Kentucky's 
rationales for including different numbers of sedimentation basins at 
the site. We have added to the report information on the recent 
progress made on the north-south diversion ditch, but we disagree with 
DOE's assertion that we included post-closure costs in our comparison 
of past cleanup costs and schedules. We have, however, included post-
closure costs as part of our discussion of DOE's total financial 
responsibilities at Paducah. Nevertheless, we have revised the report 
to more clearly indicate that post-closure environmental monitoring 
costs are a separate activity from cleanup activities and related 
costs.

In their written comments, EPA commended GAO for a fair and balanced 
analysis of the challenges that the three parties face in the 
environmental cleanup at the site. Kentucky stated that the report was 
a fair and accurate assessment of both the progress at the site and the 
working relationship among the three parties since 2000. Both EPA and 
Kentucky agreed with the report's two recommendations.

DOE and Kentucky also provided technical comments, which we 
incorporated into the report as appropriate. DOE's, EPA's, and 
Kentucky's written comments are presented inAppendixes I, II, and III, 
respectively.Appendix I also includes our responses to DOE's comments.

Scope and Methodology:

To determine the amount of money DOE has spent on cleanup-related 
activities, the purposes for which the money has been spent, and the 
estimated total for the site, we interviewed officials from DOE's Oak 
Ridge Operations Office, which is responsible for managing costs for 
the Paducah site, and reviewed budget documents including appropriation 
data related to the cleanup. During two visits to the Paducah site, we 
interviewed the representative from Bechtel Jacobs responsible for 
finance, reviewed expenditure and project data from 1988 through 2003, 
and estimated out-year expenditures. Specifically, we obtained and 
analyzed historic and estimated expenditures for the major expenditure 
categories of the cleanup--remedial and removal actions, environmental 
risk assessments, base operations, and their subcomponents--as well as 
cost estimates for other activities required to close the site, 
including final decontamination and decommissioning of the uranium 
enrichment process plant, and long-term environmental monitoring at the 
site. We reported all 1998-2003 expenditures in 2002 dollars. To assess 
the reliability of the DOE cost information, we interviewed Bechtel 
Jacobs staff responsible for the databases containing the data that 
were provided. We obtained and reviewed descriptions of the databases, 
how data are entered into the databases, quality control checks on the 
data, and testing conducted on the data. We also reviewed in detail a 
year's coding of the data into the categories of interest to us. After 
taking these steps, we determined that the data provided to us were 
sufficiently reliable for the purposes of this report.

To assess the status of DOE efforts to clean up the contamination at 
the site, we had Bechtel Jacobs representatives provide a written 
status of what actions have been taken to address waste and 
contamination for each cleanup category: groundwater, surface water, 
surface soils, legacy waste stored at the site, DOE material storage 
areas, waste burial areas, and contaminated unused building and 
structures. We also reviewed various documents, such as an evaluation 
of a new technology for removing TCE from groundwater, to further 
document actions taken in the various categories. In addition, during 
two visits to the Paducah site, we interviewed representatives from 
Bechtel Jacobs responsible for finance and planning, as well as other 
activities regarding the status of DOE's cleanup. We also interviewed 
DOE's Office of Environmental Management site officials regarding 
progress achieved. During the two visits to Paducah, we toured the site 
to get a further understanding of how these cleanup actions were 
undertaken and implemented. We also interviewed officials from DOE's 
Office of Environmental Management in Washington, D.C.

To determine which of the challenges we previously identified continue 
to be issues for DOE at Paducah, we interviewed the Assistant Secretary 
and other headquarters officials from DOE's Office of Environmental 
Management to obtain a high-level perspective on these challenges. We 
also interviewed DOE's Office of Environmental Management site 
officials regarding progress achieved under each category. During our 
two visits to Paducah, we toured the site to develop a firsthand 
understanding of the cleanup challenges. Furthermore, on each visit we 
interviewed representatives from Bechtel Jacobs responsible for the 
cleanup, finance, and planning regarding the status of the challenges 
and actions taken to address them, and reviewed site-specific 
documents, including the September 2002 life cycle baseline, the 
federal facility agreement, and the May 2003 and November 2003 site 
management plans. To obtain a complete perspective on the four 
previously identified challenges, we interviewed officials from EPA 
Region IV, the Commonwealth of Kentucky's Department for Environmental 
Protection, and the Governor of Kentucky, and reviewed related studies 
and correspondence. We also interviewed the Chairman of the Paducah 
Site Specific Advisory Board, attended one of the board's monthly 
meetings, interviewed the Chairman of the Greater Paducah Economic 
Development Council and the Chairwoman of the Paducah Chamber of 
Commerce, and consulted with GAO's Chief Technologist on these 
challenges. We reviewed studies of various cleanup technologies, site-
specific progress reports, DOE's Top-to-Bottom report, and testimony 
from congressional hearings.

To identify potential solutions to the challenge of a lack of 
stakeholder agreement on the cleanup approach, we interviewed officials 
from DOE's Office of the Inspector General and reviewed relevant 
reports, interviewed DOE and state officials at other cleanup sites 
where DOE has worked successfully with regulators to implement an 
accelerated plan such as Rocky Flats, Colorado, and reviewed National 
Academy of Science reports regarding the benefits of technical peer 
review.

We are sending copies of this report to the Secretary of Energy, the 
Administrator of the Environmental Protection Agency, and the Secretary 
of the Kentucky Natural Resource and Environmental Protection Cabinet. 
We will also make copies available to others upon request. In addition, 
the report will be available at no charge on the GAO Web site at

March 12, 2004:

Ms. Robin M. Nazzaro:

Director, Natural Resources and Environment 
United States General Accounting Office 
Washington, D.C. 20548:

Dear Ms. Nazzaro:

We appreciate the opportunity to review and comment on the General 
Accounting Office (GAO) draft report entitled NUCLEAR WASTE CLEANUP: 
DOE Has Made Some Progress in Cleaning Up the Paducah Site, but 
Challenges Remain. We have reviewed the draft report twice and are 
disappointed that this second version neither fully reflects the extent 
of the comments and concerns we previously shared with the GAO staff, 
nor does it fully acknowledge recent significant progress at the site.

We disagree with the GAO's findings regarding our decision to stop 
participating in the Core Team process. The report characterizes DOE's 
decision as cutting off a "collaborative" process with the regulators, 
which is not accurate. The Core Team was collaborative in concept, but 
in practice, resulted in staff making decisions without senior 
management policy input. DOE discontinued its participation on the Core 
Team to ensure that decisions for the site were made based on risk and 
regulatory requirements, and that actions were being taken consistent 
with policy set forth by senior management. Although the Core Team was 
disbanded, DOE continued to collaborate with the regulators, albeit at 
the senior management level. Staff was encouraged to continue 
collaborating and exchanging information as appropriate. DOE and the 
regulators have made significant progress and working relationships 
have improved since the signing of the Agreed Order with Kentucky in 
October 2003. This fact is not properly reflected in the report.

DOE is concerned that, while the draft report states that the GAO's 
review covers a time period from April 2003 to March 2004, most of the 
strides taken in the past six months at the site are not adequately 
represented. For example, DOE has successfully accelerated its cleanup 
on two of the five sections of the north-south diversion ditch. 
Excavation and construction to remove contaminated soils from Section 2 
is complete, and Section 1 excavation is projected to be completed this 
fiscal year, a year ahead of schedule. Your report fails to indicate 
completion of the Section 2 work and states that DOE is planning to 
complete the work by 2005.

In other areas of concern, the report continues to include post-closure 
environmental monitoring with cleanup costs. Post-closure costs should 
not be 
included in comparisons of past cleanup estimates or schedules. Also, 
although we accept our share of the responsibility, the report does not 
balance the responsibility for damaged relationships and delayed 
progress on all parties.

Enclosed are our specific comments addressing our concerns. We agree 
that DOE still faces many challenges to accomplishing a safe, cost-
effective cleanup at the Paducah site. DOE remains committed to meeting 
our responsibilities and complying with the terms of its agreements 
with the regulators.

If you have any further questions, please call me on (202) 586-7709, or 
Mr. William Murphie, Manager Portsmouth/Paducah Project Office, on 
(859) 219-4001.

Sincerely,

Jessie Hill Robeison 
Assistant Secretary for Environmental Management:

Enclosure: 

The following are GAO's comments on the Department of Energy's letter 
dated March 12, 2004.

GAO Comments:

1. We disagree. We believe that the report accurately describes DOE's 
decision to discontinue the Core Team process. This approach, 
established as a result of congressional hearings held in 1999, was 
designed as a collaborate process to advance progress at the site. 
Furthermore, EPA and Kentucky viewed this effort as a collaborative 
process. As we state in the report, DOE became concerned about the 
growing scope of the cleanup and the associated increase in costs, and 
believed that the Core Team's recommended actions were excessive. While 
discussion of the cleanup did continue at the senior management level, 
according to Kentucky officials and DOE site staff and contractor 
officials, DOE staff at the Paducah site were instructed by DOE 
headquarters not to continue discussing the cleanup with regulatory 
officials.

2. Our report does reflect the progress DOE and Kentucky have made in 
addressing near-term cleanup impediments, such as the signing of the 
agreed order that resolved outstanding regulatory violations. However, 
the long history of mistrust and lack of shared vision on the cleanup 
approach at Paducah, and the inability of the three parties to agree to 
and sign the fiscal year 2004 Site Management Plan, issued in draft in 
November 2003, indicate that the parties' relationship remains a 
challenge.

3. We have modified the final report to reflect DOE's recent progress 
on the excavation of the north-south diversion ditch.

4. We disagree with DOE's statement that we included post-closure costs 
in our comparison of past cleanup costs and schedules. For example, 
post-closure costs are not included in the comparison of current and 
past cleanup estimates and schedules presented in table 2. However, 
because we believe that it is important to provide a complete picture 
of DOE's financial responsibilities at the Paducah site, we did include 
post-closure costs as part of our discussion of DOE's total financial 
responsibilities at Paducah. We have also revised our report to more 
clearly indicate that post-closure environmental monitoring costs are a 
separate activity from cleanup activities and related costs.

5. We disagree with DOE's statement that our report does not provide a 
balanced presentation of all three parties' responsibilities for the 
past poor working relationship and delayed progress. We cite throughout 
our report examples of disagreements between DOE and the regulators, 
providing each side's position on these issues. For instance, we 
describe the disagreement over a sampling plan for soil excavation at 
the north-south diversion ditch. We also present DOE and Kentucky's 
positions over whether available data was adequate to warrant the 
installation of sedimentation basins at the site.

Director, Natural Resources and Environment 
U. S. General Accounting Office:
441 G Street, NW 
Washington, DC 20548:

Dear Ms. Nazzaro:

Thank you for the opportunity to review a draft of the forthcoming 
General Accounting Office (GAO) report entitled Nuclear Waste Cleanup: 
DOE Has Made Some Progress in Cleaning Up the Paducah Site, but 
Challenges Remain (GAO-04-457). I would like to commend the GAO for a 
fair and balanced analysis of the challenges the Department of Energy 
(DOE), Environmental Protection Agency (EPA) and the Commonwealth of 
Kentucky (KY) face in the environmental cleanup at the Paducah Gaseous 
Diffusion Plant (PGDP) . I would also like to note that the report is 
based on a November, 2003, draft DOE Site Management Plan (SMP) about 
which EPA had serious concerns. The current version of the SMP, 
delivered as a final draft on February 27, 2004, addresses many of our 
concerns, and indicates that DOE, EPA and KY may be close to agreement 
on the overall plan for environmental assessment and cleanup at the 
PGDP. Reaching consensus on this plan would provide important stimulus 
to progress of cleanup at this site.

Another significant issue addressed in your report concerns cost and 
schedule uncertainty in the cleanup of the PGDP. EPA believes that if 
DOE plans and implements site studies, whereby actual data will replace 
estimates and assumptions about the scope of cleanup, uncertainty in 
cost and schedules can be reduced. The recommendations in the report 
that DOE involve the regulators earlier and establish an external peer 
review group would also expedite the implementation of site studies and 
cleanup activities.

Again, I would like to thank you for the opportunity to comment.

Sincerely,

Signed by:

Ms. Robin M. Nazarro, Director 
Natural Resources and Environment 
United States General Accounting Office 
441 G. Street NW, Room 2J27 
Washington, DC 20548:

Dear Ms. Nazarro:

The Commonwealth of Kentucky's Environmental and Public Protection 
Cabinet (Cabinet) has received your draft report to Congressional 
committees regarding the progress of environmental clean up at the 
Paducah Gaseous Diffusion Plant. I appreciate the opportunity for 
review and input that GAO has afforded the Cabinet in the formulation 
of this document.

The Cabinet finds the draft report to be a fair and accurate assessment 
of both the progress at the site and the working relationship among 
DOE, USEPA and the Cabinet since 2000. The taxpayers of the United 
States and the stakeholders of the Paducah Gaseous Diffusion Plant 
deserve much better than the disputes and cleanup delays chronicled in 
your report. Please know that a priority of this Cabinet is to work 
effectively with DOE and USEPA to improve the working relationship 
described in the draft report.

The Cabinet is encouraged by and agrees with GAO's recommendation that 
DOE involve Kentucky and USEPA early in the development of both overall 
cleanup plans and specific projects in order to resolve concerns and 
reach timely consensus on cleanup decisions. The Cabinet also 
recognizes 
the merit of GAO's recommendation that DOE, in conjunction with 
Kentucky and USEPA, identify external technical peer review groups with 
environmental cleanup expertise who can facilitate timely resolution of 
any future differences. To that end, I will direct my staff to explore 
this recommendation with DOE and USEPA. Lastly in this regard, the 
Cabinet believes that any peer review group so engaged should be free 
of any contractual agreements with the agencies, beyond the agreement 
necessary to conduct the peer review.

Attached please find specific comments on the draft report provided by 
the Cabinet's Division of Waste Management. These comments are 
primarily offered to clarify factual information in the draft report.

However, there are some comments, particularly pertaining to the burial 
grounds at the PGDP that speak more broadly to the Cabinet's position 
with regards to those areas.

I hope you will find this correspondence and the attached comments to 
be helpful, and again I thank you for the opportunity to review and 
provide input on this important document.

funded through the normal DOE budget process.

[5] According to the DOE site manager for Paducah, DMSAs and legacy 
waste are not included in the draft 2004 site management plan in order 
to provide the department flexibility in deciding how best to conduct 
the overall cleanup.

the plant ceases operations in approximately 2010 or be deferred to a 
later date.

[8] The 2019 completion date represents completion of phase I of DOE's 
proposed cleanup plan.

[9] The proposed cleanup approach is outlined in DOE's draft fiscal 
year 2004 site management plan.

[10] Depleted uranium hexafluoride is typically stored in large steel 
cylinders. Although there are different sized cylinders in use, most of 
the cylinders contain 14 tons (12 metric tons) of uranium hexafluoride.

[11] Our earlier testimony stated that these costs, in addition to the 
money already spent on the Paducah cleanup, would total over $13 
billion. These preliminary results were represented in actual dollars. 
Since then we have converted the estimated future costs to fiscal year 
2002 constant dollars. 

[12] DOE and Kentucky resolved this and other disputed violations in an 
October 2003 settlement agreement. As part of the settlement, DOE 
agreed to pay Kentucky $1 million. 

[13] In its comment on this report, DOE provided updated information on 
actions taken for the surface water and DMSA categories which we have 
included in the report.

[14] A plume is defined as the area occupied by a groundwater 
contaminant after it has begun to spread, through diffusion or other 
forces, away from its point of origin. 

[15] According to DOE, this estimate is based on the assumptions that 
TCE was used at the site from 1953 to 1993 and that a fixed amount was 
released to the ground each day. A high degree of uncertainty surrounds 
this estimate, and the actual amount of TCE released cannot be 
verified. 

[16] DOE estimates that about 810,000 cubic feet of material and 
equipment are stored in the 160 DMSAs at Paducah. About 180,000 cubic 
feet of this volume is fixed equipment.

[17] Using permeable treatment barriers involves injecting a 
gelatinous, gummy substance called guar gel into the aquifer (an 
underground geological formation or group of formations that contain 
water and a source of groundwater for wells and springs) to treat 
groundwater as it flows through the treated area. 

[18] According to DOE officials, Paducah currently has the largest TCE 
contamination source in the United States. They speculate that if the 
estimated 180,000 gallons of TCE contaminating the groundwater and 
associated soil were left untreated, it could take 7,000 years for the 
contamination to completely dissipate (attenuate) into the environment. 
However, DOE contractor officials told us that if the TCE is treated 
aggressively, complete attenuation could occur in roughly 700 years. 

[19] DOE expects to request a 2.5 percent increase for inflation 
annually. 

[20] According to USEC's director of communications, for planning 
purposes USEC assumes that the plant will be in operation until about 
2010.
