Highlights of GAO-08-1081, a report to the Subcommittee on Energy and 
Water Development, Committee on Appropriations, House of 
Representatives. 

Why GAO Did This Study: 

The Department of Energy (DOE) spends billions of dollars annually to 
clean up nuclear wastes at sites that produced nuclear weapons. Cleanup 
projects decontaminate and demolish buildings, remove and dispose of 
contaminated soil, treat contaminated groundwater, and stabilize and 
dispose of solid and liquid radioactive wastes. Ten of these projects 
meet or nearly meet DOE’s definition of major: costs exceeding $1 
billion in the near term—usually a 5-year window of the project’s total 
estimated life cycle. 

GAO was asked to determine the (1) extent to which the cost and 
schedule for DOE’s major cleanup projects have changed and key reasons 
for changes, and (2) factors that may hinder DOE’s ability to 
effectively manage these projects. GAO met with project directors and 
reviewed project documents for 10 major cleanup projects: 9 above the 
near-term $1 billion threshold, and 1 estimated to cost between $900 
million and $1 billion over the near term. 

What GAO Found: 

Nine of the 10 cleanup projects GAO reviewed had life cycle baseline 
cost increases, from a low of $139 million for one project to a high of 
nearly $9 billion for another, and life cycle baseline schedule delays 
from 2 to 15 years. These changes occurred primarily because the 
baselines we reviewed included schedule assumptions that were not 
linked to technical or budget realities, and the scope of work included 
other assumptions that did not prove true. Specifically, the schedules 
for 8 of the 10 projects were established in response to DOE’s 2002 
effort to complete cleanup work, which in some cases moved up project 
completion dates by 15 years or more. For example, to meet the 2012 
accelerated completion date for its solid waste disposition project, 
DOE’s Idaho National Laboratory assumed it would process waste at a 
rate that was more than 50 percent higher than the rate demonstrated at 
the time it established the baseline. When the laboratory could not 
meet that processing rate, DOE revised its baseline, adding 4 years and 
about $450 million to the project. Also, most of the 10 projects had 
cost increases and schedule delays because the previous baselines (1) 
had not fully foreseen the type and extent of cleanup needed, (2) 
assumed that construction projects needed to carry out the cleanup work 
would be completed on time, or (3) had not expected substantial 
additional work scope. 

DOE has not effectively used management tools—including independent 
project baseline reviews, performance information systems, guidance, 
and performance goals—to help oversee major cleanup projects’ scope of 
work, costs, and schedule. For example, DOE’s independent reviews meant 
to provide reasonable assurance that a project’s work can be completed 
within the baseline’s stated cost and schedule, have not done so for 4 
of 10 projects. For one project, the baseline was significantly 
modified as little as 7 months after it had been revised and validated 
by the independent review, while other projects have experienced life 
cycle cost increases of as much as $9 billion and delays of up to 10 
years, within 1 to 2 years after these reviews. In addition, although 
DOE uses several types of reporting methods for overseeing cleanup 
projects, these methods do not always provide managers with the 
information needed to effectively oversee the projects or keep Congress 
informed on the projects’ status. For example, sites’ proposals for 
changes to projects’ cost and schedule baselines do not always identify 
possible root causes, and DOE does not systematically analyze the 
proposals for common problems across its projects. Therefore, DOE may 
be missing opportunities to improve management across projects. In 
addition, guidance for key management and oversight functions are 
spread across many different types of documents and are unclear and 
contradictory. As a result, project managers do not consistently 
implement this guidance, which may lead, for example, to problems in 
effectively managing risks across projects. Finally, DOE recently 
changed its goals for “successful” cleanup projects, reducing the 
amount of work and raising the allowable cost increases against the 
near-term baseline. DOE has initiated several actions to improve 
project management, but it is too early to determine whether these 
efforts will be effective. 

What GAO Recommends: 

GAO is making a number of recommendations, such as expanding the 
content of performance reports provided to DOE senior managers and 
information provided to Congress to better reflect current status of 
near-term and life cycle baseline cost and schedules and reasons for 
significant changes; and strengthening DOE guidance and baseline 
reviews, among other things. In commenting on a draft of this report, 
DOE agreed with GAO’s recommendations.

The Honorable Peter J. Visclosky: 
Chairman: 
The Honorable David L. Hobson: 
Ranking Member: 
Subcommittee on Energy and Water Development: 
Committee on Appropriations:
House of Representatives: 

The Department of Energy (DOE) spends billions of dollars annually to 
clean up nuclear wastes at sites across the nation that produced 
nuclear weapons. Cleanup projects decontaminate and demolish buildings, 
remove and dispose of contaminated soil, treat contaminated 
groundwater, and stabilize and dispose of solid and liquid radioactive 
wastes, among other things. DOE's Office of Environmental Management 
(EM) currently oversees more than 80 of these cleanup projects, 
primarily at government-owned, contractor-operated sites throughout the 
nation. Some of these highly complex projects have completion dates 
beyond 2050. Ten of these projects meet or nearly meet DOE's definition 
of "major": projects whose costs exceed $1 billion in the near-term-- 
usually a 5-year window of the project's total estimated life cycle. 
[Footnote 1],[Footnote 2] These 10 projects have combined estimated 
near-term costs of almost $19 billion and combined life cycle costs 
estimated to range between $115 billion and $143 billion, and they 
account for almost half of EM's $5.5 billion fiscal year 2009 budget 
request.[Footnote 3] These 10 projects are described in detail in 
appendix II and include the remediation, decontamination, and 
decommissioning, or the stabilization and disposition of: 

* solid waste at Idaho National Laboratory, Idaho; 

* nuclear facilities at the East Tennessee Technology Park, Oak Ridge 
Reservation, Tennessee; 

* nuclear materials at the Savannah River Site, South Carolina; 

* radioactive liquid tank waste at the Savannah River Site, South 
Carolina; 

* soil and water at Los Alamos National Laboratory, New Mexico; 

* nuclear materials at the Hanford Site, Washington; 

* solid waste at the Hanford Site, Washington; 

* soil and water at the Hanford Site, Washington; 

* nuclear facilities at the River Corridor Closure Project, Hanford 
Site, Washington; and: 

* radioactive liquid tank waste at the Office of River Protection, 
Hanford Site, Washington.[Footnote 4] 

DOE established Order 413 in 2000 to provide project management 
guidance for construction projects--projects that build large complexes 
often housing unique equipment and technologies that process waste or 
other radioactive material--and nuclear waste cleanup projects. 
[Footnote 5],[Footnote 6] In 2005 and 2007, EM, in conjunction with 
DOE's Office of Engineering and Construction Management (OECM), issued 
further guidance to better tailor the order's requirements to the 
cleanup projects. This guidance lays out protocols directing DOE 
project managers to establish a life cycle baseline for cleanup 
projects that includes three key parts: (1) prior year actual costs; 
(2) a near-term estimate of the scope of the cleanup work (the cleanup 
activities needed to achieve project goals), cost, and schedule of the 
cleanup activities (the near-term is generally for 5 years, or the 
duration of the contract, whichever is longer); and (3) out-year 
estimates through project completion for those projects that extend 
beyond the near term.[Footnote 7] The near-term and out-year estimates 
also identify the amount of contingency monies that could be needed to 
cover potential project risks.[Footnote 8] 

Major cleanup projects take years to complete, and often involve unique 
challenges and a high degree of complexity; therefore, it is critically 
important that EM develop and implement a rigorous, disciplined 
approach for developing and managing the baselines. Such an approach 
includes planning and managing work activities, cost, and schedule to 
achieve project goals in a stable, controlled manner over the near term 
and the entire life of the project. DOE has taken several steps to 
establish such an approach, including the following: 

* EM must formally approve changes to the near-term and life cycle 
baseline. 

* Project managers must provide formal and informal reports to DOE 
headquarters staff, including data entries into databases and quarterly 
performance reports. These reports contain, among other things, earned 
value management (EVM) data--a measure of progress against a cost and 
schedule baseline. Widely used in industry, earned value data makes it 
possible for managers and others to determine how a project has been 
performing and to predict future performance trends. Furthermore, both 
the Office of Management and Budget (OMB) and DOE Order 413 require the 
use of EVM data, and GAO has developed best practices on how to use the 
data.[Footnote 9] 

* As stipulated in DOE Order 413, OECM must independently review 
project baselines at critical project stages; OECM conducts these 
reviews largely with the help of external technical experts. 
Specifically, for cleanup projects that cost $100 million or more, OECM 
must review a project's proposed baseline to provide reasonable 
assurance that the project can be successfully executed. OECM also 
examines technical scope, cost, schedule, and avoidance and mitigation 
plans for possible cost and schedule overruns, as well as proposed 
project management. 

Overall, we and others have reported over the past two decades that 
project management weaknesses have impaired DOE's major projects. In 
1990, we designated DOE's contract management (which includes project 
management) as a high-risk area for fraud, waste, abuse, and 
mismanagement. In addition, in 1999, the National Academies' National 
Research Council developed recommendations to address weaknesses in 
DOE's project management. Recently, in 2007, we reported that DOE had 
improved its approach to project management but that performance on 
DOE's projects had not substantially improved.[Footnote 10] Also in 
2007, the National Academy of Public Administration reported 
specifically on EM's management of nuclear waste and complimented EM on 
its improvements in project management, but also raised questions about 
EM's ability to follow through on them. Furthermore, reviews by DOE's 
Office of Inspector General, the Department of Defense's Army Corps of 
Engineers (Army Corps), and the National Research Council, among 
others, have advised DOE on how to better manage its major projects. 

In this context, you asked us to determine the (1) extent to which the 
cost and schedule for DOE's major cleanup projects have changed and the 
key reasons for these changes, and (2) factors that may hinder DOE's 
ability to effectively manage these cleanup projects. 

To determine the extent to which DOE cleanup projects are experiencing 
cost or schedule changes and key reasons contributing to these changes, 
we spoke with DOE project directors and reviewed project management 
documents for 10 of EM's major cleanup projects--9 projects above the 
near-term $1 billion threshold, and 1 estimated to cost between $900 
million and $1 billion over the near term. For our analysis, we 
examined the life cycle baseline reported as of the most recent 
contract awards or major contract modifications--which occurred between 
2004 and 2007--and compared these baselines with the updated baselines 
at the time of our review (dollar amounts used in calculating cost 
increases are in fiscal year constant 2008 dollars). We conducted site 
visits and analyzed project documentation, such as project plans, 
independent reviews, contractor performance data, plans to avoid or 
mitigate project risks, and documents prepared to guide and control 
formal changes to the baseline. We also identified factors that may 
hinder DOE's ability to effectively manage projects in accordance with 
approved life cycle baselines primarily through a review of project 
documents and interviews with project officials. Because we and others 
have previously expressed concern about the data reliability of a key 
DOE project management tracking database--the Project Assessment and 
Reporting System--we did not develop conclusions or findings based on 
information generated through that system.[Footnote 11] Instead, we 
collected information directly from project site offices and 
contractors. In addition, we spoke with officials from EM and OECM in 
Washington, D.C. We provided an interim briefing to the Subcommittee on 
the status of our work on April 3, 2008. 

We conducted this performance audit from March 2007 to September 2008 
in accordance with generally accepted government auditing standards. 
Those standards require that we plan and perform the audit to obtain 
sufficient, appropriate evidence to provide a reasonable basis for our 
findings and conclusions based on our audit objectives. We believe that 
the evidence obtained provides a reasonable basis for our findings and 
conclusions based on our audit objectives. Appendix I contains a 
detailed description of our scope and methodology. 

Results in Brief: 

Nine of the 10 cleanup projects we reviewed have experienced cost 
increases and schedule delays in their life cycle baseline, ranging 
from $139 million for one project to more than $9 billion for another, 
and schedule delays ranging from 2 years to 15 years. These changes 
arose primarily because the initial baselines made schedule assumptions 
that were not linked to technical or budget realities, and the scope of 
work included other assumptions that did not prove true. Specifically: 

* Baselines were not linked to technical or funding realities. The 
schedules for 8 of the 10 projects we reviewed were established in 
response to EM's 2002 effort to accelerate cleanup work, which in some 
cases moved up project completion dates by 15 years or more. EM wanted 
to complete cleanups earlier to better safeguard public health and the 
environment, among other things. However, these dates were not always 
tied to technical capabilities or likely funding realities. For 
example, to meet the 2012 accelerated completion date for its solid 
waste disposition project, DOE's Idaho National Laboratory assumed its 
waste treatment plant could process waste at a rate that was more than 
50 percent higher than the rate demonstrated at the time EM established 
the baseline. When the waste treatment plant did not meet that 
processing rate, EM revised its baseline, deferring 4 years of cleanup 
work, which added about $450 million to the project. In addition, 
before April 2007, according to several EM officials, project managers 
were directed to establish cost baselines to meet the accelerated 
schedules without considering likely funding for the projects. As a 
result, most projects did not receive funding as planned for in the 
baselines, hindering their ability to complete the work on time. In 
April 2007, EM changed its strategy: It limited its funding for all 
sites and directed that future baselines be based on the expected 
budget for each site. In part because of this change, some completion 
dates were extended by as much as 15 years. 

* Baselines' scope of work included optimistic assumptions that did not 
prove true. Most of the projects we reviewed also experienced cost 
increases and schedule delays because the initial baselines had (1) not 
fully anticipated the type and extent of cleanup that would be needed, 
(2) assumed that construction projects needed to carry out the cleanup 
work would be completed on time, or (3) assumed the scope of work 
activities needed to finish the project would not increase. For 
example, at a 1940s-era building being demolished at Oak Ridge as part 
of the nuclear facility decontamination and decommissioning project, 
the contractor found that the building was far more contaminated and 
deteriorated than first estimated and had to reinforce the structure in 
order to safely remove contaminated equipment before demolishing the 
building. Primarily because these activities had not been adequately 
anticipated in the baseline, project costs rose by $1.2 billion and 
completion was extended by 9 years, to 2017. Similarly, the baselines 
for four of the major cleanup projects assumed that a related, major 
construction project would be completed on schedule and available for 
the cleanup project to use. For example, a 5-year delay in the 
completion of Hanford's major construction project--the Waste Treatment 
Plant (WTP)--was the most significant factor behind extending the 
radioactive liquid tank waste project's schedule by 10 years, and 
increasing its life cycle costs by $4.8 billion. The delay in WTP's 
startup date resulted in additional years required to store the waste 
in the tanks and then to operate the treatment plant. 

DOE has not always effectively used management tools--including 
independent project baseline reviews, performance information systems, 
guidance, and performance goals--to help oversee major cleanup 
projects' scope of work, costs, and schedule. Specifically: 

* DOE's independent reviews of project baseline estimates, meant to, 
among other things, provide reasonable assurance that a project's work 
activities can be accomplished within the baseline's stated cost and 
schedule, have not done so for 4 of the 10 projects we reviewed. The 
baselines for these 4 projects were significantly modified shortly 
after review, revision, and validation. For one project, the baseline 
was significantly modified as little as 7 months after it had been 
revised and validated based on the independent review, while other 
projects had experienced additional life cycle cost increases of as 
much as $9 billion and delays of up to 10 years, within 1 to 2 years 
after the baseline reviews. As a result, the usefulness of the 
independent baseline reviews is questionable when significant baseline 
changes occur very shortly after the reviews are completed. 

* EM managers do not always receive the information needed to 
effectively manage major cleanup projects or provide detailed reports 
to Congress on the projects' status. First, sites' proposals for 
changes to cost and schedule baselines do not consistently identify 
reasons for the changes or possible root causes, and EM does not 
systematically analyze the proposals for common problems across its 
projects. As a result, EM may be missing opportunities to apply lessons 
learned across projects. Second, in certain cases, the use of EVM data 
did not conform to industry standards or best practices identified by 
GAO, in part because the data contained anomalies that skewed analyses 
or lacked important information on future staffing needs. Third, EM's 
quarterly performance reports neither consistently provide accurate 
information about a project's performance against the near-term 
baseline, nor do they include information about how current performance 
may affect the life cycle baseline. Finally, DOE's reports to Congress 
do not include important information that would aid oversight, such as 
the extent of and reasons for significant changes to near-term and life 
cycle baseline estimates. In contrast, Department of Defense reports to 
Congress on acquisitions for major systems provide detailed information 
on significant cost and schedule changes and the reasons for those 
changes. 

* Guidance for key management and oversight functions--such as project 
baseline development, risk management, and contingency funding--is not 
consolidated, and is contradictory and unclear. Consequently, project 
managers do not consistently implement this guidance. For example, DOE 
headquarters officials found that project managers are calculating 
contingency funding to cover project risks in their baselines in a 
variety of ways, leading to uncertainty regarding the total contingency 
funds needed to cover all cleanup projects. 

* DOE recently changed its goals for the performance of cleanup 
projects. Before 2008, a major cleanup project was expected to achieve 
100 percent of the scope of work in its life cycle baseline with less 
than a 10 percent cost increase in the project's life cycle baseline. 
However, according to EM's current cleanup project performance goal, 
the projects are successful if they achieve at least 80 percent of the 
scope of work in their near-term baselines with less than a 25 percent 
cost increase. The new performance goal permits up to 20 percent of the 
scope of work to be deferred from the near term to out years, creating 
a substantially greater risk that life cycle costs will continue to 
increase and that completion dates will be delayed. According to DOE 
officials, the agency adjusted performance goals primarily to account 
for the greater level of uncertainty inherent in cleanup projects. 
However, by lowering expectations for adhering to near-term baselines, 
DOE may inadvertently be creating an environment in which large 
increases to life cycle costs become not only more common, but accepted 
and tolerated. 

* Over the past 2 years, EM has begun a series of efforts to better 
manage its projects and address long-standing problems. For example, 
under its "Best-in-Class" Project Management Initiative, EM senior 
managers have expressed a strong commitment to improving project 
performance, and under this initiative, EM contracted with the Army 
Corps to assess project management, and then identified 18 priority 
actions to correct known problems. Although these efforts are ongoing, 
EM has yet to combine them into a formal plan, and it is too early to 
tell whether these efforts will prove effective. 

We are making a number of recommendations to the Secretary of Energy to 
improve management of major cleanup projects, including to report more 
complete information to senior DOE management and Congress so that they 
can be fully informed about project status and make informed decisions 
about these projects; consolidate, clarify, and update guidance for 
managing cleanup projects; consolidate all planned and ongoing EM 
improvements into a comprehensive corrective action plan; and develop 
the independent baseline reviews to better assure that project work 
scope can be completed within the baselines' stated cost and schedule. 

We provided a draft of this report to the Department of Energy for its 
review and comment. DOE agreed with our recommendations but provided 
some suggested changes to them, and provided specific comments on the 
overall report, which we incorporated as appropriate. We discuss DOE's 
comments in detail at the end of this letter. DOE also provided some 
technical comments, which we incorporated as appropriate. DOE's 
comments are provided in appendix IV. 

Background: 

DOE oversees and implements its major cleanup projects through 
agreements with contractors who operate the nuclear weapons research 
and production sites and the cleanup projects at those sites. Some of 
EM's cleanup projects are located at DOE sites administered by the 
National Nuclear Security Administration, a separately organized agency 
within DOE. 

EM's major cleanup projects involve efforts to clean up sites where 
nuclear weapons were produced and production waste stored.[Footnote 12] 
EM's cleanup projects handle a wide array of waste types and levels of 
radioactivity and hazardous constituents, and can involve multiple 
activities to, among other things, retrieve, characterize, treat, 
package, store, transport, and dispose of the waste, as well as 
disassemble, treat, package, store, transport, and dispose of the 
contaminated containers or processing lines/equipment used for weapons 
production or for storing or treating the waste. Multiple EM cleanup 
projects can occur at a single DOE site responsible for a multitude of 
other noncleanup-related activities. The cleanup projects are organized 
generally around similar waste types and activities. For example, the 
soil and water remediation activities at each site are organized under 
one umbrella, as are the nuclear facility decontamination and 
decommissioning projects, and the radioactive liquid tank waste 
projects, among others. EM generally manages these similar work 
activities, grouped into a category known as a Project Baseline 
Summary, through numerical designations; for example, all activities 
for soil and water remediation are grouped under Project Baseline 
Summary 30. (See app. II for additional information on the 10 DOE major 
cleanup projects reviewed.) 

Funding for and Costs of DOE's Major Cleanup Projects: 

Unlike construction projects, which are funded on a line item basis, 
cleanup projects receive funding through operating funds designated for 
each DOE site. In 2003, EM began applying project management principles 
contained in DOE Order 413 to these cleanup projects in order to apply 
more discipline and rigor in planning and expending these project 
funds, among other things. 

A cleanup project can cost several billion dollars and its life cycle 
can span several decades. EM divides the life cycle baselines for its 
major cleanup projects into three distinct parts--prior year costs, 
near term (usually a 5-year period), and out year (through project 
completion). Life cycle costs for each project range from a low of 
almost $1.7 billion to over $44 billion, and some projects might not be 
completed until after 2050.[Footnote 13] (See app. III for detailed 
information on the life cycle baseline costs for the 10 projects we 
reviewed.) 

EM applies different approaches to managing these wastes, depending on 
the type and extent of contamination and the state or federal 
regulatory guidelines and milestones it needs to comply with. DOE has 
agreements with state and federal regulators to clean up sites, and the 
agreements lay out a framework for determining the cleanup standards to 
be met. Furthermore, because all projects have a certain degree of 
uncertainty, such as not fully knowing the condition of buried waste 
containers, EM needs to plan for this uncertainty and identify ways to 
prevent serious disruption to projects should problems arise. To 
address this uncertainty, DOE Order 413 requires project managers to 
identify contingency funds that may be needed to cover potential cost 
increases stemming from a variety of project risks, including technical 
complexities, regulatory issues, and funding shortfalls. Although EM 
project managers build contingency funding into their near-term and out-
year estimates, EM management does not generally include funding in its 
budget requests to cover contingency for cleanup projects until after 
it is actually needed to address a problem; therefore, EM contingency 
for cleanup projects has been referred to as "unfunded contingency." 

Earned Value Management for Tracking Work Progress: 

To be effective, program managers need information on program 
deliverables and on the progress made in meeting them. One method that 
can help program managers track this progress is EVM data. These data 
include, for example, detailed information on budgeted costs and actual 
costs for work scheduled and work performed, as well as forecasted 
costs at project completion. Among other things, EVM data can be used 
to compare (1) budgeted costs to actual costs and (2) the value of work 
accomplished during a given period with the value of work scheduled for 
that period. By using the value of work completed as a basis for 
estimating the cost and time to complete a project, EVM data should 
alert program managers to potential problems sooner than expenditures 
alone can. 

As a key management tool, EVM has evolved from an industrial 
engineering concept to a government and industry best practice to 
better oversee programs. Both OMB and DOE Order 413 require the use of 
EVM. OMB Circular A-11, part 7, requires the use of an integrated EVM 
system across an entire program to measure how well the government and 
its contractors are meeting a program's approved cost, schedule, and 
performance goals. The American National Standards Institute and the 
Electronic Industries Alliance have jointly established a national 
standard for EVM systems.[Footnote 14] Recognizing the benefits of 
having these national standards, OMB states in its 2006 Capital 
Programming Guide that major acquisitions that require product 
development are to require that contractors use an EVM system that 
meets the American National Standards Institute guidelines.[Footnote 
15] In addition, DOE Order 413 requires that projects with total 
cleanup costs of $50 million or more use an EVM system that complies 
with industry standards and is certified by DOE's OECM to comply with 
these standards. 

GAO also has developed EVM best practices that, when followed, can help 
project managers consistently develop and analyze EVM data to gain a 
complete and accurate understanding of project status. Among other 
things, our guidance on EVM states that (1) EVM data should not have 
data errors and anomalies that may skew and distort the EVM analysis, 
and (2) information such as staffing levels and the root causes of and 
corrective actions for cost and schedule variances should be reported 
through the EVM system. 

Major Cleanup Projects Experienced Billions of Dollars in Additional 
Costs and Schedule Delays, Primarily because Initial Baselines Were 
Overly Optimistic: 

Nearly all the cleanup projects we reviewed have had cost increases and 
schedule delays in the life cycle baseline, as much as $9 billion for 
one project, and schedule delays of as much as 15 years for two 
projects. These cost increases and schedule delays occurred primarily 
because the previous baselines for these projects had schedule 
assumptions that were not linked to technical or budget realities, and 
other assumptions also proved to be overly optimistic. 

Major Cleanup Projects' Costs Have Increased by Billions and Schedules 
Have Been Delayed by As Much As 15 Years: 

The estimated costs of the 9 of the 10 DOE major cleanup projects we

[A] For purposes of this report, previous cost estimates are the life 
cycle cost estimates created at the beginning of the most recent 
contract period for operation of the DOE site or the most recent major 
contract modification or extension, which in many cases coincided with 
the beginning of the project's previous near-term baseline. Current 
life cycle cost estimates are based on the most recently approved near- 
term baseline, out-year planning estimate ranges, or both. 

[B] EM recently began using cost estimate ranges rather than point 
estimates. According to EM officials, costs at the lower end of the 
ranges were estimated at the 50 percent level of confidence, while 
costs at the upper end of the ranges represent the 80 percent level of 
confidence. For this report, our analysis of cost change uses the lower 
end of the range, which excludes contingency, because contingency 
amounts can vary widely between projects and are not typically funded 
before they are needed. 

[C] We calculated the percentage of cost increase on the basis of 
constant 2008 dollars to make them comparable across projects and to 
show real increases in cost while excluding increases due to inflation. 

[D] As of August 2008, this project has not registered a cost increase. 
However, project officials told us that they expect to file a baseline 
change proposal increasing the life cycle cost by at least several 
hundred million dollars by the end of December 2008. 

[End of table] 

As the table shows, estimated costs increased from a minimum of $139 
million for one project to more than $9 billion for another project. 
The smallest dollar and percentage increase--$139 million, or 9 
percent--occurred at Los Alamos' soil and water remediation project, 
which is focused on cleaning up known or suspected chemical and 
radiological contamination in addition to treating soil and groundwater 
that was contaminated by this waste. This project, however, is expected 
to further increase its life cycle cost estimate. The largest dollar 
increase among the 10 major projects--more than $9 billion--was for 
Hanford's radioactive liquid tank waste project, which is expected to 
remove, treat, and dispose of more than 56 million gallons of high- 
level radioactive waste in 177 underground storage tanks. In fact, the 
other radioactive liquid tank waste project, at Savannah River, 
registered the second largest dollar increase--almost $7 billion. 
However, the largest percentage increase--about 64 percent--occurred at 
Oak Ridge's nuclear facilities decontamination and decommissioning 
project. 

Table 2 shows that 8 of the 10 projects we reviewed experienced delays 
in scheduled project completion, ranging from 2 years to 15 years.

[A] For purposes of this report, previous project completion dates 
represent the estimates at the beginning of the new contract period for 
operation of the DOE site or the major contract modification or 
extension, which typically coincided with the beginning of the 
projects' current or previous near-term baseline. Current completion 
date estimates represent the most recently approved near-term baseline 
or out-year planning estimate ranges calculated at the 50 percent 
confidence level at the lower end of the range, to the 80 percent level 
of confidence at the higher end of the range. EM recently began using 
schedule estimate ranges rather than point estimates. For this report, 
our analysis of schedule change uses the lower end of the range.

[End of table] 

As table 2 shows, the shortest delay is at Hanford's nuclear material 
stabilization and disposition project, while the longest delays--15 
years--also are at Hanford: the soil and water remediation and the 
solid waste stabilization and disposition projects. 

Overly Optimistic Baselines Contributed to Significant Changes in 
Projects' Life Cycle: 

The changes in schedule and costs occurred primarily for two reasons. 
First, initial project baselines were built on accelerated schedules 
that were not always linked to technical capabilities or available 
budgets, although EM has begun to tie its new baselines to anticipated 
funding. Second, the initial baselines included other assumptions that 
did not hold true, including conditions on the ground at the sites, 
expected completion dates for related construction projects, and 
activities that would be included in projects' scopes of work. 

Baseline Schedules Were Not Linked to Technical or Funding Realities: 

The initial baselines for 8 of the 10 major projects we reviewed 
contained schedules that were influenced by an EM-wide effort to 
accelerate the office's cleanup work. In 2002, EM management worked 
with its sites and regulators to create new, earlier milestones for 
completing key cleanup projects and for closing entire sites to reduce 
the public health and environmental risks posed by the waste at these 
sites. Before this effort, some of the major cleanup projects were not 
estimated to complete work until the 2030s and 2040s. Under the 
accelerated schedules, four projects' completion dates were moved up by 
15 years or more, as was the case for the radioactive liquid tank waste 
stabilization and disposition project at the Hanford site; its 
completion date was moved from 2048 to 2028. The baselines containing 
the accelerated schedules--those generally created between 2003 and 
2006--tied their work scope and funding assumptions to the completion 
dates and not necessarily to available cleanup technologies. For 
example: 

* Solid waste stabilization and disposition project at Idaho. To meet 
its accelerated completion date of 2012--down from 2018--DOE's Idaho 
National Laboratory assumed its Advanced Mixed Waste Treatment Plant 
could process nuclear waste at a rate of about 8,500 cubic meters per 
year--more than 50 percent faster than the rate of about 5,400 cubic 
meters per year demonstrated when DOE established the baseline. At the 
time, because the plant had only recently begun operating, project 
staff lacked confidence that they could meet the processing rate. 
Moreover, the independent team reviewing the baseline reported that the 
rate was optimistically high. Nevertheless, DOE proceeded with the 
initial baseline, increasing the amount of unfunded contingency in its 
baseline and attempting to meet the optimistic rate by providing the 
contractor with performance incentives. Still, the processing rate has 
fallen short of baseline assumptions--it is currently roughly 6,000 
cubic meters per year. To reflect this more realistic rate, DOE 
subsequently revised its baseline, adding 4 years to the project 
schedule and increasing costs by about $450 million. 

* Radioactive liquid tank waste stabilization and disposition project 
at Savannah River. This project, in part, combines high-level 
radioactive waste stored in tanks at the Savannah River Site with 
melted glass and places it in canisters ultimately to be sent to a 
federal repository for disposal. DOE directed that the project's 
completion date be accelerated, from 2035 in its early planning 
documents to 2019 in the initial baseline. In order to make that date, 
according to project officials, they included some assumptions in the 
initial baseline they knew at the time would be difficult to realize. 
Specifically, they assumed that the project's waste processing facility 
could produce canisters consisting of up to 49 percent high-level 
waste--with the remaining space filled with melted glass--when at the 
time it had not been able to produce a canister containing more than 42 
percent high-level waste with an existing technology while remaining 
within the acceptance criteria for the federal repository. Those 
criteria dictate specific characteristics, including durability and 
leachability for the glass-waste mixtures in the canisters. DOE has 
since adjusted these assumptions--the current waste processing plan 
assumes the canisters will contain 34 percent to 38 percent high-level 
waste using the existing technology--contributing to the overall cost 
increase and schedule delay for this project. 

These early baselines also were not tied to expected funding. According 
to several senior EM officials, before April 2007, project directors 
were instructed to create cost baselines to meet the accelerated 
schedules and their regulatory milestones without regard for the likely 
funding the projects could expect to receive. Consequently, the funding 
assumptions in the projects' baselines were higher than the amount of 
funding DOE requested each year. According to a senior EM budget 
official, these shortfalls required project managers to continually 
adjust cost and schedule baselines as projects moved work activities 
into the out years to accommodate the lower funding levels. For 
example, according to site officials at Oak Ridge, when DOE did not 
request the full amount of funding in the nuclear facility's 
decontamination and decommission project's initial baseline, the 
project could not complete all the work as planned. Project managers 
responded by pushing work activities into the out years, which 
contributed, in part, to the project's overall cost increase and 
schedule delay. Similarly, as noted in a recent DOE internal audit, 
according to Los Alamos officials, funding has not been sufficient to 
meet the site's regulatory commitments, and has been a concern since 
2003, when the site manager said he was concerned that appropriate 
resources had not been identified to conduct the necessary 
environmental restoration activities.[Footnote 17] 

According to EM managers, they have implemented changes to the way 
baselines are created that address these problems. In April 2007, EM 
changed its policy for creating project baselines. Instead of tying 
baselines to the accelerated schedules and regulatory commitments with 
unconstrained funding, EM limited funding for its sites, directing that 
all future baselines be based on expected budget numbers generated for 
each site. 

For three of the projects we reviewed, this change in direction 
resulted in deferral of work and schedule delays because the new 
funding levels represented significant reductions in what projects were 
planning on receiving, and these projects were low on EM's priority 
list.[Footnote 18] For example, Hanford's solid waste stabilization and 
disposition project's funding was reduced to the point where it will 
receive minimal funding for the next 4 years in order to allow full 
funding of Hanford's decontamination and decommissioning project at 
River Corridor, a higher priority. During this period, to comply with 
the funding levels provided, the project will maintain minimum 
activities to safeguard materials and will not advance its waste 
processing goals. As a result, according to project officials, life 
cycle costs for this project increased in some part to reflect a longer 
schedule and the additional costs of having to hire and train new 
workers in the future to complete a job that already was underway. 

Not all sites have implemented these changes, however. EM's direction 
to all sites to create their baselines tied to the funding profile 
outlined in the June 2007 policy memo has not been applied to two of 
the major cleanup projects. The Hanford radioactive liquid tank waste 
stabilization and disposition project--the most expensive cleanup 
project--and the Los Alamos soil and water remediation project have not 
aligned their baselines with the funding targets. The Hanford project's 
baseline was validated just before the policy change took place and, 
for the period between 2009 and 2030, the baseline contains about $2.6 
billion more than the funding targets.[Footnote 19] Similarly, EM 
approved the baseline for the Los Alamos project even though it was not 
aligned with the funding targets. The baseline identifies a projected 
funding shortfall each year through 2012 that peaks at a cumulative 
$236 million in 2010. This shortfall does not include an additional 
$947 million in unfunded contingency. At the same time EM approved the 
baseline, it directed project managers at the site to change the 
baseline to bring its costs in line with the targets. 

Another likely contributing factor to the cleanup projects' cost 
increases and extended schedules is DOE's practice of not including 
contingency funding in its annual budget requests for EM's cleanup 
projects. Specifically, EM has requested enough funding for its cleanup 
projects to ensure a 50 percent likelihood of completing the projects 
within the total estimated project costs. However, the requested amount 
generally has not included contingency funding, which project managers 
may have to use in order to complete a project on time by addressing 
risks that materialize during cleanup. For example, in 2007, the 
radioactive liquid tank waste project at Hanford had an unexpected 
spill of 85 gallons of radioactive material from one of its storage 
tanks; this spill required shutting down waste retrieval operations for 
11 months in order to clean up the spill. Even though the retrieval 
operations represent a small percentage of the overall work scope 
ongoing at the project, the accident added at least $8 million to the 
retrieval cost for that one tank. Furthermore, in accordance with EM 
policy, projects are expected to account for the costs of such 
potential risks by increasing the amount of unfunded contingency in 
their near-term and life cycle baselines. Because funding for that 
contingency is not included in the budget request, however, increasing 
the amount of contingency funding in the near-term baseline is largely 
a paperwork exercise that has no active impact on preventing or solving 
problems or anticipating actions that could offset demonstrated slow 
progress. 

According to a December 2007 report by the National Academy of Public 
Administration, EM's practice of not funding contingency for its 
cleanup projects has meant that EM has not had additional funding 
available to address emergency problems when they arise and therefore 
has either taken money from another project or extended the schedule of 
the work into future fiscal years to manage them. Furthermore, 
according to EM officials, by providing enough funding for its projects 
to ensure that they have a 50 percent chance of meeting their project 
cost and schedule baselines, EM recognizes that 5 of the 10 major 
projects are likely to miss their cost and schedule goals. In contrast, 
DOE funds its construction projects at a level that reflects a greater 
probability of success--80 percent--an amount that reflects the 
industry standard for such projects. According to senior EM officials, 
EM does not fund contingency for its cleanup projects because allotting 
enough funds to cover the costs of risks that may not materialize would 
constrain the amount of work EM could perform for the money it receives 
each year. However, in accordance with a recommendation from the 
National Academy of Public Administration, EM is evaluating its 
practice of not including contingency funding in its budget requests 
for cleanup projects. 

Baselines Included Assumptions about the Scope of Work and Technical 
Challenges That Did Not Hold True: 

For most of the projects we reviewed, EM included assumptions in its 
baselines that (1) did not represent the conditions at some of the 
major projects, (2) did not sufficiently anticipate delays in the 
completion of related construction projects, and (3) the scope of work 
activities to be accomplished would not increase. Correcting these 
assumptions often led to changes in the scope of work, higher costs, 
and extended schedules. 

First, for four of the projects we reviewed--Oak Ridge's nuclear 
facility decontamination and decommissioning project, Idaho's solid 
waste stabilization and disposition project, and Savannah River and 
Hanford's radioactive liquid tank waste stabilization and disposition 
projects--site conditions were worse than project staff originally 
estimated, leading to significant changes to the life cycle baseline. 
[Footnote 20] For example, at the Oak Ridge project, because a 1940s-
era building was far more contaminated and deteriorated than first 
estimated, DOE changed its cleanup plan and implemented a more 
extensive--and therefore more expensive--approach to tearing down the 
building. After a worker fell through a weakened floor, the contractor 
had to first reinforce the building's structure so that contaminated 
equipment could be removed safely. Primarily because project officials 
did not accurately anticipate the site conditions or the types of work 
activities necessary to safely conduct the work--despite multiple 
estimates generated by the contractor, DOE, and the Army Corps--this 
project's costs increased by $1.2 billion and significant amounts of 
work were delayed, extending the completion date by 9 years, to 2017. 

Similarly, the initial baseline for the radioactive liquid tank waste 
stabilization and disposition project at Hanford assumed that 99 
percent of the waste contained in the 177 storage tanks could be 
removed by using only one type of technology to retrieve the tank 
waste. However, DOE subsequently determined that almost half of the 
tanks contained a hardened layer of waste that could not be removed 
with the chosen technology and therefore a second technology was needed 
to remove this waste. Correcting the optimistic assumptions--adding the 
second technology and re-estimating the costs of retrieving waste from 
the tanks based on field experience gained--increased the baseline by 
more than $2 billion. 

Second, delays in completing related construction projects directly 
contributed to schedule delays--and corresponding cost increases--for 
four of the cleanup projects we reviewed. Three of these projects are 
at the Hanford site in Richland, Washington. The initial baselines for 
these projects included assumptions that the major construction project 
there--the Waste Treatment Plant (WTP)--would be ready to begin 
operations in 2011. In 2006, DOE extended the WTP construction 
completion date by 5 years, resulting in schedule extensions for three 
cleanup projects.[Footnote 21] The major cleanup project that will run 
the WTP--the radioactive liquid tank waste stabilization and 
disposition project--had to increase its life cycle cost estimate by 
about $4.8 billion and extend its schedule by 10 years in order to 
safely maintain the waste storage tanks while the treatment plant is 
being built and to operate the plant for additional years, among other 
things. Similarly, in response to the WTP delay, the schedules for the 
solid waste stabilization and disposition project and the soil and 
water remediation project were extended by 15 years--increasing costs 
by more than $4 billion combined. These projects cannot complete their 
missions until the WTP has finished processing all of the liquid waste 
in the storage tanks. According to the currently approved baselines, 
the liquid tank waste project will complete its operations in 2042, and 
activities under the latter two projects are not expected to be 
completed until 2050.[Footnote 22] However, as we recently reported, 
DOE has acknowledged that the start of waste treatment operations will 
be delayed by at least 8 years (from 2011 to 2019), not 5 years, which 
will likely affect further these projects' costs and schedules. 
[Footnote 23] 

Third, for three of the projects we reviewed, increases in work scope-
-the activities required to complete the project--contributed to cost 
increases and schedule delays. For example, a major contributor to the 
more than $3 billion cost increase and at least 9-year schedule delay 
at the nuclear materials stabilization and disposition project at 
Savannah River was DOE's approval of a new initiative in 2006 that 
added additional amounts of nuclear materials for the project's 
facilities to disposition, including materials from other DOE sites. 
Those facilities were originally scheduled to complete their mission in 
2007--the new scope extended the mission until 2019.[Footnote 24] 
Similarly, Savannah River's other major cleanup project--radioactive 
liquid tank waste stabilization and disposition--also had significant 
scope added. Under a law passed in 2004,[Footnote 25] DOE determined 
that the salt waste in its tanks is not high-level waste and therefore 
can be disposed of at the site instead of in a geologic repository. The 
law required DOE to consult with the Nuclear Regulatory Commission when 
making this determination. According to DOE, this consultation and the 
resulting changes to the cleanup process added significant scope to the 
project, causing DOE to lengthen the estimated time to close the 49 
tanks at the site. 

According to EM, most of the cost increases and schedule delays 
experienced by the major cleanup projects were the direct result of 
unrealized aggressive planning assumptions. EM has since recognized 
that project baselines must be based on realistic technical and 
regulatory assumptions and be planned on the basis of realistic out 
year budget profiles. However, it appears that the practice of 
incorporating optimistic assumptions into project baselines has not yet 
been eliminated. As we recently reported, some of the underlying 
assumptions in the baseline for the Hanford radioactive liquid tank 
waste project may be overly optimistic.[Footnote 26] For example, DOE 
assumes that the tanks will remain viable throughout what has become a 
protracted waste treatment process, with some tanks expected to remain 
in service more than 60 years longer than originally anticipated. This 
extended operation raises the risk of tank failure and leaks to the 
environment. The baseline also assumes that emptying single-shell tanks 
will proceed significantly faster than it has to date. Hanford project 
management officials have since acknowledged that the ambitious 
retrieval schedule might not be achievable and are adjusting their 
planning estimates. 

DOE Has Not Effectively Used Available Management Tools to Help Control 
Major Cleanup Projects' Scope of Work, Costs, and Schedule: 

While DOE has several mechanisms in place to help manage cleanup 
projects, including independent reviews, performance information 
systems, guidance, and performance goals, it has not always used them 
to effectively manage major cleanup projects' scopes, costs, and 
schedules. 

DOE's Baseline Reviews Highlight Problems but Have Not Succeeded in 
Ensuring Work Can Be Accomplished within Stated Cost and Schedule: 

OECM's independent reviews of the baselines, meant, among other things, 
to provide reasonable assurance that the project's work activities can 
be accomplished within the stated cost and schedule, have not done so 
for four of the projects we reviewed. Instead, these baselines were 
significantly modified shortly after approval. As a result, the 
usefulness of the independent baseline reviews is questionable when 
significant baseline changes occur very shortly after the reviews are 
completed, as the following discussion illustrates. 

The advanced mixed waste treatment project under Idaho's solid waste 
stabilization and disposition project. OECM's 2006 independent review 
accurately noted that the project baseline submitted for validation for 
the treatment plant included an unrealistic rate for processing waste-
-more than 50 percent faster than the rate demonstrated at the time the 
baseline was established. In response, project officials proposed 
correcting the problem primarily by increasing the amount of unfunded 
contingency in the baseline, a move that reflected common practice 
within EM, and OECM officials approved this action and validated the 
baseline. As the panel predicted, the project's actual processing rate 
after its baseline was validated was slower than expected. Within 7 
months of OECM's validation of the near-term baseline, project 
officials proposed modifying it. DOE had to defer the activities that 
the contractor was not able to accomplish in the near term, extending 
the project life cycle by about 4 years and increasing costs by about 
$450 million. We believe that DOE's approval of increasing unfunded 
contingency as a corrective action for an unrealistic processing rate 
was ineffective.[Footnote 27] Although DOE also attempted to increase 
the processing rates through contractor performance incentives, we 
believe DOE should have revised the baseline using a more realistic 
processing rate to calculate baseline cost and schedule before 
validating it. 

Oak Ridge's nuclear facility decontamination and decommissioning 
project. Significant cost increases began 2 years before OECM's 
independent validation of the project in 2006, and have continued to 
increase. Specifically, life cycle costs for the project were estimated 
at $1.8 billion in 2004--the beginning of the project's previous near- 
term baseline--with expected project completion by fiscal year 2008. By 
August 2006, when OECM completed its review of the baseline and issued 
its validation recommendation, life cycle costs for the project had 
grown to about $2.2 billion and project completion was extended by 
about 1 year. However, roughly 1 year after OECM validated the 
baseline, EM revised it again, adding about $800 million in costs and 
delaying project completion by an additional 8 years. EM justified the 
change because, among other things, it wanted to adjust the baseline to 
conform to new funding targets as directed by DOE in June 2007 and to 
account for other changes it needed to make in its approach to 
decontaminating the building. 

Los Alamos soil and water remediation project. In March 2008, EM 
approved an independent review of this project and the associated 
baseline although it expected that the baseline would change. According 
to the EM memorandum approving the baseline, changes in EM's priorities 
and funding plans were likely to necessitate changes to the Los Alamos 
project's baseline, and the project was directed to submit a baseline 
change that would align the baseline with funding targets. OECM 
officials also acknowledged that their independent review of the 
baseline was based on assumptions that would likely not prove to be 
true. Specifically, OECM's review assumed that the project would 
receive the full funding needed even though DOE's funding targets at 
the time were below the funding levels needed to comply with the state 
cleanup agreement. As a result, project officials expect that the 
estimated life cycle costs of nearly $1.7 billion will increase 
substantially during 2008 but could not tell us the extent of the cost 
and schedule change until they receive DOE's new funding commitments 
for the project. 

Hanford's radioactive liquid tank waste stabilization and disposition 
project. The most significant cost increase--more than $9 billion-- 
occurred about 2 years after DOE's initial independent review and 
approval of this project. The project's baseline was first approved in 
2004, with life cycle costs expected to be about $22 billion and 
completion scheduled for 2032. However, in 2006, life cycle costs 
increased to about $31 billion--not including an additional $8.6 
billion in unfunded contingency--and the completion date was extended 
by 10 years, to 2042. Project officials expect the baseline will 
require another update and independent review in 2009 to reflect 
anticipated changes as a result of the project's new contractor and 
because of changes resulting from ongoing negotiations with state 
regulators over regulatory agreement milestones. 

In addition to changes to the baselines soon after the independent 
reviews, DOE has recently relaxed standards used for conducting these 
reviews. In 2003, DOE issued standard operating procedures for 
conducting independent reviews--primarily of construction projects. 
These procedures stated that baselines should be considered, once 
approved, as set in concrete. The EM-OECM 2005 protocol--and its 2007 
update--for cleanup projects replaced the standard operating procedures 
and directed OECM to validate only the near-term baseline for cleanup 
projects while reviewing the life cycle estimate "for reasonableness." 
In this way, EM and OECM sought to acknowledge what they believe are 
the greater uncertainties present in the out-years of a cleanup project 
compared with a typical construction project. However, within a year of 
the 2007 protocol, OECM had changed its approach for EM cleanup 
projects from validating baselines to "certifying" them, which is a 
more limited statement of assurance than validation. Specifically, 
according to OECM officials, certification means that the near-term 
baselines are reasonable if near-term baseline costs are funded as 
outlined in the baseline and contingency funds are provided as needed. 
The change is intended to reflect OECM's belief that, because funding 
for cleanup projects is more uncertain than for construction projects, 
the same confidence level cannot, nor should, be applied to reviews of 
EM cleanup project baselines as it is applied to construction projects. 
Since EM headquarters does not consistently provide contingency funds 
for its cleanup projects, and half of the major projects have 
significant contingencies in their near-term baselines, the most likely 
result for projects experiencing problems is to extend schedules and 
increase life cycle costs. In commenting on a draft of this report, 
OECM stated it intends to go back to validating near-term baselines for 
cleanup projects, assuming, in part, that funding becomes more stable 
and EM gains greater experience managing near-term baselines. 

DOE Lacks Reliable and Consistent Performance Information: 

DOE managers depend on data about the performance of EM's major cleanup 
projects to make informed decisions about how best to handle unexpected 
events and manage shifting priorities. DOE site and headquarters staff 
generate a number of regular reports to update senior managers on the 
status of these projects, both to justify making significant changes to 
project baselines and to request funding from Congress. Although these 
reports provide valuable information to managers on the progress of 
work at cleanup sites around the country, they do not consistently 
provide the key information needed to make fully informed management 
decisions about EM's major cleanup projects. Specifically, (1) 
proposals for baseline changes do not consistently identify reasons for 
proposed changes or possible root causes that contributed to problems, 
(2) use of EVM data does not consistently conform to industry standards 
or GAO's best practices, (3) quarterly reports do not always describe 
the impact of contractor performance on near-term or life cycle costs 
and schedules, and (4) reports to Congress on the status of and changes 
to major cleanup projects are limited to a small snapshot in time and 
do not provide information necessary for effective oversight. 

EM Baseline Change Reports Do Not Consistently Include Needed 
Information: 

When a project reaches a point at which it is likely to miss the goals 
in its baseline, project managers are required to propose changes to 
the project's cost, schedule, or scope baseline, a process that is akin 
to hitting the reset button. EM project managers request such a change 
by, among other things, documenting certain information in a Baseline 
Change Proposal report, including current approved costs and new 
proposed costs, proposed project start and end dates, and a 
justification for the changes. For the key change proposals we reviewed 
for the major cleanup projects, the information provided describing the 
changes and their impacts varied widely, with some projects providing 
little to no explanatory information about what led to the change and 
others explaining the causes of the changes in detail. For example, a 
change proposal for Hanford's nuclear material stabilization and 
disposition project simply described the project's scope of work and 
did not provide any explanation for why the project's schedule was 
being delayed by 3 years, while a proposal from Savannah River's 
radioactive liquid tank waste stabilization and disposition project 
included information on the causes for its cost and schedule changes, 
as well as the specific cost and schedule impacts of each cause. 
However, the change proposals we reviewed generally did not address the 
root causes that resulted in the changes to the baseline. For example, 
the Savannah River change proposal explained that almost $500 million 
of the total proposed cost increase was due to revising the strategy 
for finishing the project. However, the proposal did not explain why 
this strategy needed revision. In investigating the reason for this 
proposed revision, we determined that a robust strategy for finishing 
the project was not included in the original baseline because the 
project was directed to meet a completion date of 2025 and could not do 
so if it included the thorough closure strategy. Without including this 
kind of information in the proposals, it would be difficult for EM 
managers to effectively identify the true causes of the baseline 
changes, take steps to address them, and transfer any lessons learned 
to other projects. 

In addition, EM does not centrally gather and systematically analyze 
the narrative information in the baseline change proposals. We 
recognize that such information is not easily analyzed to identify 
common causes across projects. However, without such analysis, EM 
senior managers are potentially hindered in addressing problems 
collectively. One EM project management official agreed that having the 
ability to analyze the information in the change proposals across 
projects would be beneficial, but that his office had not yet made it a 
priority to collect this information because it was still addressing 
reliability issues with the data in the change proposals. 

EM has made some effort to identify root causes of its project 
management problems. It recently participated in a DOE-wide effort to 
identify root causes of project and contract management problems in 
response to GAO's inclusion of DOE's contract management on its high- 
risk list.[Footnote 28] However, DOE's analysis was focused more on 
construction projects than EM cleanup projects. The report notes that 
the emphasis of the effort was on the capital line item--construction-
-projects, but that several of the issues identified also are 
applicable to other projects, including EM cleanup projects.[Footnote 
29] According to one project participant from OECM, the participants 
discussed how some of the issues raised related to cleanup projects but 
they did not examine those projects as extensively as the construction 
projects. In commenting on a draft of this report, DOE explained that 
its analysis was based more on data from construction projects than EM 
cleanup projects because more data exist documenting DOE's past project 
management deficiencies for construction projects since those projects 
have a longer history of a structured, disciplined management process. 

Use of Earned Value Data Does Not Always Conform to Industry Standards 
or GAO-Identified Best Practices: 

At three of the major cleanup projects--nuclear facilities cleanup at 
the Hanford Site's river corridor cleanup project, solid waste 
stabilization and disposition at Idaho National Laboratory, and soil 
and water remediation at Los Alamos National Laboratory--we found 
several instances in which the use of EVM data did not conform to 
industry standards or our best practices.[Footnote 30] As a result, EM 
and site project managers using the data may be less able to make 
informed decisions to effectively manage these projects. 

Data anomalies. For all three projects, the EVM systems we assessed 
contained data errors or anomalies that could potentially distort the 
analysis of EVM data. Anomalies included, for example, reporting 
negative actual costs or reporting costs that are not tied to work 
scheduled or performed. The Los Alamos EVM data contained both types of 
these anomalies, which may have distorted the results of data analyses 
by as much as $34 million, preventing managers from understanding the 
true status of project performance. According to project officials, the 
anomalies occurred primarily because Los Alamos had initially assigned 
costs to a general account, and waited up to several months before 
assigning these costs to the correct specific work activities. In 
another case, in a significant number of instances the contractor at 
Hanford's river corridor closure project reported costs incurred for 
work activities performed that had not been scheduled to start until 
future years, skewing the reported performance results.[Footnote 31] 
The contractor explained that these data anomalies occurred because it 
had performed work sooner than originally expected--and therefore the 
work was not incorporated into the project's EVM planned schedule in 
the periods for which it was actually performed. Project officials at 
the site stated that they believe the EVM information, as reported, 
correctly represents the project's status. As such, the summary-level 
EVM data seem to depict a favorable schedule performance in April 2008; 
however, our independent analysis of this data shows that when we 
removed the value of the work that was started and completed ahead of 
schedule, the remainder of the originally scheduled work was actually 
behind schedule in April 2008, and trends indicated that the variance 
was worsening. 

Data on the availability of staff to perform future work was not always 
developed. For one of the projects we reviewed, the EVM system lacked 
important information on staffing, contrary to GAO-identified best 
practices. DOE officials at Los Alamos' soil and water remediation 
project told us they plan to begin asking for staffing information from 
the contractor, and contractor officials stated they are setting up a 
staffing report within their EVM system. Without this information, 
project managers lack important information necessary for ensuring that 
they have, or will have, an adequate number and type of staff to 
perform the upcoming scheduled work. 

Reliability of earned value systems is questionable. OECM has certified 
that the earned value system used to report performance for only one of 
the three systems we assessed meets the required industry standards. 
[Footnote 32] The EVM system used by the contractor operating the 
advanced mixed waste treatment project--a significant portion of the 
solid waste stabilization and disposition project at the Idaho National 
Laboratory--has not been reviewed by OECM to determine whether it is 
compliant with industry standards, and contractor officials stated they 
believed their system does not meet the standards. In addition, OECM 
was in the process of reviewing the system used by the contractor 
responsible for the soil and water remediation project at Los Alamos 
National Laboratory at the time of our review. As a result, these 
projects lack the necessary assurances that the EVM data were free of 
errors and anomalies that could skew and distort the EVM analyses. 

Once a system is certified as meeting the standards, regular 
surveillance is needed in order to ensure its continued compliance. 
Surveillance allows managers to focus on how well a contractor is using 
its EVM system to manage cost, schedule, and technical performance, and 
is important because it monitors problems with performance and the EVM 
data. If these kinds of problems go undetected, EVM data may be 
distorted and not meaningful for decision making. OECM's surveillance 
program is under development: it recently hired one staff person to 
lead its surveillance efforts, and is developing a guide to better 
define its surveillance protocol. DOE also requires its sites to 
perform surveillance of EVM monthly contractor performance data, which 
includes developing EVM surveillance plans and conducting random EVM 
surveillance. 

Furthermore, EM managers do not appear to consistently gather or 
analyze EVM data to maximize the data's benefits for project 
management. GAO best practices recommend that EVM system reports 
include thorough narrative explanations of any root causes of, or 
proposed corrective actions, for reported cost and schedule variances 
shown in the data. For the soil and water remediation project at Los 
Alamos, for example, EM did not require that this information be 
reported by its contractor. As a result, EM project managers at Los 
Alamos have not always received the information necessary for ensuring 
that effective corrective actions are implemented to prevent additional 
changes to the cost and schedule baselines. According to contractor 
officials, they reported information on root causes and corrective 
actions to EM routinely before fiscal year 2008, but DOE asked them to 
stop providing it. According to the project director for the soil and 
water remediation project at Los Alamos, the Los Alamos Site Office 
Assistant Manager had directed the contractor to not provide the 
variance reports as part of its project status reviews because the 
contractor's explanation of these variance reports during scheduled 
meetings was taking several hours to review and wanted instead to use 
the available time to focus more on risk management and other project 
issues. However, according to this site official, the site office's 
direction was not intended to discontinue all variance analysis 
reporting. Although the contractor discontinued including the variance 
analyses reports in its project status reviews, the project director 
stated that DOE continues to obtain information from the contractor by 
other means, such as cost performance reports and weekly contractor 
meetings at which DOE and the contractor discuss the root causes of 
variances that resulted in risks to meeting milestone compliance 
agreements. However, contractor cost performance reports we reviewed 
did not provide any narrative information on causes or corrective 
actions. Furthermore, the weekly contractor meetings discuss only 
certain root causes of the variances that resulted in risks to 
milestone compliance agreements and therefore are neither comprehensive 
nor documented. Because verbal information can easily be forgotten, 
lost, or misinterpreted, among other things, we believe that a written 
report would be a best practice. 

In addition, EM projects report their EVM data to headquarters managers 
at the project summary level, which can mask problems occurring in the 
project that more detailed reporting could reveal. At Idaho, in early 
2008, EVM data showed the solid waste stabilization and disposition 
project was performing ahead of schedule and under cost, although major 
problems had occurred at the advanced mixed waste treatment project-- 
the primary subproject. Without EVM reports that contain more specific 
detail, project managers at headquarters may not recognize that a 
problem is occurring until it becomes large enough to recognize at the 
summary project level of reporting. In addition, greater detailed 
information provided to managers earlier in the project potentially 
could allow for early intervention. 

Beyond more detailed reports, some project managers in the field and at 
headquarters have not always systematically reviewed or independently 
analyzed the EVM data they received, which also would help improve 
their understanding, as well as mitigate potential problems occurring 
within a project. At one site we visited, the DOE official receiving 
the data said he did not analyze the information before entering it 
into the EM headquarters database. In turn, headquarters EM project 
managers told us they also do not analyze the EVM data the projects 
report. One oversight official indicated he would prefer to analyze the 
information he receives from the projects but he did not have the time 
required to do so. A senior EM project management official told us that 
he recognizes this deficiency and is working to address it: EM intends 
to pilot a new software package that will allow managers to analyze EVM 
data. According to EM, the software will enable EM managers to drill 
down into the EVM data received from the contractors, thus improving 
their oversight capabilities. In addition, according to EM project 
management officials, EM has insufficient federal staff to conduct 
oversight, which is being addressed as part of an ongoing effort to 
improve project management. In commenting on a draft of this report, EM 
stated it also intends to provide additional EVM training for its 
analysts. 

Quarterly Reports Do Not Present a Comprehensive Picture of Performance 
against Near-Term or Life Cycle Commitments: 

In accordance with Order 413, EM senior managers, including the 
Assistant Secretary, receive quarterly updates on the status of the 
major cleanup projects. Two key reports are the quarterly project 
reviews (QPR), generated by EM project managers, and a quarterly 
project status report created by OECM. These reports contain contractor 
performance data and information about new or ongoing issues that need 
addressing at the sites, but do not always describe how contractor 
performance affects performance against the near-term or life cycle 
baselines. Without this information, managers cannot develop a 
comprehensive assessment of progress against agreed-upon goals. 

The QPRs and OECM quarterly reports we reviewed largely use EVM data to 
assess project performance, but these data only reflect performance 
against the current contract period. Current contract period start and 
end dates do not line up with the start and end dates of the near-term 
baselines for any of the major cleanup projects we reviewed, and 
contract goals have not always been tied to what would be necessary to 
meet near-term baseline goals.[Footnote 33] For example, we found the 
EVM data for Idaho's solid waste stabilization and disposition project-
-including the advanced mixed waste treatment subproject--that was 
reported in the QPRs and OECM quarterly reports from early 2008 did not 
line up with the near-term baseline because the advanced mixed waste 
treatment project's contract period was not the same as the near-term 
baseline period, which ends in 2012. EVM data for this project are 
reported as a combination of work done by two contractors: disposal of 
low-level and mixed-low-level waste, among other things, by the major 
site contractor, whose contract runs through 2012, and the advanced 
mixed waste treatment project operations contractor, who, in early 
2008, was operating under a contract extension that expired in April 
2008, 4 years shy of the end of the near-term baseline. In addition, 
according to project officials, the goal of processing 15,500 cubic 
meters of waste contained in that contract extension was not based on 
what was necessary to meet the near-term baseline goal of processing 
65,000 cubic meters of waste by 2012, which was DOE's commitment at the 
time of the extension. Since the advanced mixed waste treatment 
project's activities make up about 75 percent of the cost baseline for 
the overall project, EVM data for this project as reported in the QPRs 
and OECM quarterly reports were not an accurate indicator of how the 
project was performing against the approved near-term baseline. DOE has 
further extended the advanced mixed waste treatment project contract 
through September 2009, and project officials explained the current 
extension is better linked to the current baseline, meaning EVM data 
reported should represent a better indication of performance against 
that baseline. 

In addition, although the QPRs we reviewed include data on current life 
cycle cost and schedule estimates, they do not always include 
information about changes to the schedule or scope, nor do they 
explicitly mention when a change to the baseline has been proposed. 
Instead, the QPRs generally present information on life cycle cost 
increases and provide comparisons to original baselines. QPRs also 
contain a schedule for each project detailing key milestones and 
expected end dates. However, when a change to a project completion date 
is made, the schedule shown in the QPR in most cases does not preserve 
the original completion date as a point of comparison. Similarly, there 
does not appear to be any mechanism in the QPR to present a change in a 
project's scope of work, for example, a move of some work activities 
from the near term into the out years. As a result, the reports tell 
only that life cycle costs have increased, but corresponding changes to 
schedule and scope are not apparent. Furthermore, there is no clear 
place in a QPR for a project manager to mention that a baseline change 
proposal has been submitted to headquarters if the results of that 
proposal are not yet presented in the life cycle cost or schedule 
information in the report. Including mentions of pending change 
proposals may help ensure senior managers clearly understand the true 
state of a project's performance. 

A key performance indicator used in OECM's quarterly reports also may 
create the impression that a project is performing well overall when it 
is in fact encountering problems. As directed in the 2007 protocol for 
cleanup projects, OECM uses a traffic light indicator--red-yellow- 
green--as an at-a-glance way to highlight developing problems for DOE 
managers. This indicator is intended to represent expected performance 
against the approved near-term baseline and is based largely on EVM 
data. However, since projects encountering problems tend to manage 
those problems by moving work scope into the out years, the effects of 
problems occurring today show up as increases to out-year cost and 
schedule estimates and not as increases or delays in a near-term 
baseline.[Footnote 34] Therefore, a project rated "green" by OECM may 
simultaneously be experiencing increases in overall life cycle costs 
and delays in project completion. OECM officials agreed that it would 
be beneficial to present projected impacts of current performance on 
life cycle estimates wherever practical in its reports. 

EM Does Not Report Information about Significant Changes to Near-Term 
and Life Cycle Baselines to Congress: 

DOE's reports to Congress do not include key information that would aid 
oversight efforts, including the extent of and reasons for significant 
changes to near-term and life cycle baseline estimates, and the status 
of estimated life cycle costs. DOE's annual budget request to Congress 
for fiscal year 2009 for EM included funding requests for each site and 
each project, as well as the funding appropriated in fiscal years 2007 
and 2008. The budget request also contains, among other things, 
descriptive information about the sites and projects, including EM's 
major cleanup projects, and about cleanup goals, regulatory frameworks, 
and key uncertainties. However, the request did not provide any project-
specific life cycle costs or completion dates.[Footnote 35] In the 
previous three budget requests, EM had provided life cycle costs and 
planned completion dates for each project. Without this information, 
Congress cannot know what progress each project has made and the extent 
of work still needed, cannot understand how the project may be changing 
and has changed over time, and cannot know whether the project 
experienced problems since the previous budget request and the reasons 
for these problems. The absence of this information makes it more 
challenging to effectively oversee the department and its major cleanup 
projects. 

DOE has not been directed to provide such information about its major 
cleanup projects to Congress. In contrast, Congress has required the 
Department of Defense to report annually on its major defense 
acquisition programs--those costing $2 billion or more and typically 
consisting of a weapons system, such as Navy ships or fighter planes-- 
or report quarterly when programs are experiencing significant cost 
increases or schedule delays.[Footnote 36] Congress established the 
reporting requirement to improve oversight of these defense programs by 
providing visibility and accountability for any growth in cost that may 
occur. Known as Selected Acquisition Reports, each annual report 
includes information on full life cycle program costs, unit costs--the 
cost per plane or ship--and the history of those costs. A quarterly 
report also includes reasons for any change in unit cost or program 
schedule since the previous report, information about major contracts 
under the program and reasons for any cost or schedule variances, and 
program highlights. In addition, the Department of Defense includes 
development and procurement schedules, with estimated costs through 
program completion, in its annual budget justification submissions to 
Congress. 

DOE Guidance for Management and Oversight Functions Is Unclear and Not 
Implemented Uniformly across Sites: 

EM's key policies for managing its cleanup projects--including 
developing project baselines, managing risk, and planning for 
contingency funding--are not consolidated but spread across various 
guidance documents and memos and provide contradictory and confusing 
information. Although Order 413 serves as the overarching policy 
document for project management, according to EM, the order contains 
requirements that are unnecessary or expensive and awkward to implement 
for cleanup projects. EM thus has issued numerous memos outlining the 
way in which its project managers should implement the order. See table 
3 for a list of key memos we identified that contribute to project 
management guidance and policy for EM cleanup projects.

[End of table] 

As the table shows, rather than having a consolidated source for 
guidance, EM project managers must consult multiple sources to 
determine how to correctly create a baseline or calculate contingency 
funding for a project. Furthermore, some of EM's guidance includes 
vague language and various exceptions to rules, which are likely to 
contribute to a project manager's difficulty in determining how to 
implement EM policy. For example, according to the April 2007 protocol 
for cleanup projects, once a contract is awarded and a detailed near- 
term baseline is developed, a follow-up independent review will be 
required if the baseline (1) exceeds the previously validated near-term 
baseline costs by 15 percent or more, (2) increases the schedule by a 
year, or (3) modifies scope significantly. The first two conditions for 
requiring a follow-up review are tied to fairly precise numbers--15 
percent and 1 year--although there could be some question as to whether 
these numbers are to be applied to the original or reset baseline 
calculations, especially for projects that have been extended multiple 
times. However, the protocol provides no parameters for determining 
when the third condition, a "significant" scope modification, has 
occurred. 

In addition, agency officials were not able to provide us with formal 
documentation of a significant shift in policy. As explained earlier, 
OECM recently shifted from validation to certification of the cleanup 
projects' near-term baselines. In response to our request for 
documentation of the switch to certification, OECM provided us with an 
e-mail from an OECM official to a DOE Inspector General auditor that 
defined certification and explained the reasons for the change. 
According to this e-mail, the change was made to acknowledge OECM's 
belief that EM cleanup projects should not be reviewed under the same 
standard as construction projects. The OECM official also directed us 
to DOE's fiscal year 2009 budget request for an explanation of the new 
approach. While the budget request includes a description of baseline 
certification, it neither mentions that the certification is a 
departure from the previous policy, nor does the request serve as an 
adequate means of communicating a significant policy change. 

Furthermore, different guidance documents appear to be in conflict with 
one another. Specifically, EM's 2006 memo outlining its policy on 
contingency funding explained that DOE's risks associated with 
implementing a project are covered through contingency that is part of 
the "unfunded" portion of the baseline; that is, its funding is not 
requested or budgeted in advance of when it may be needed. However, a 
2008 EM memo primarily concerned with explaining a new process for 
entering baseline changes into a database contains a description of the 
elements of a near-term baseline that includes a line for "other funded 
contingency," which has been interpreted by some EM officials as 
including DOE contingency. If, according to the 2008 memo, some DOE 
contingency should be funded--requested in advance--that memo directly 
contradicts the guidance provided in the 2006 memo. However, although 
the 2008 memo states it is updating the baseline change process, it 
does not specifically state that it replaces any part of the 2006 memo. 

In part because of this confusion, project managers at cleanup sites 
have been implementing EM's contingency policy differently. According 
to EM officials, recent independent reviews have alerted senior EM 
officials to this inconsistent implementation of the policy guidance. 
The review teams found that the project managers were using a variety 
of methodologies to calculate the contingency for their projects. As a 
result, according to one EM official with expertise in contingency, 
managers were likely underestimating the amount of contingency needed 
for their projects. To address this problem, EM senior managers 
directed the creation of a contingency implementation guide to provide 
a definitive interpretation of existing EM policy on contingency, and 
this guide is expected to be issued in September 2008. 

Furthermore, at least one of DOE's policies--on independent reviews of 
cost estimates--is not being implemented at all. According to Order 413 
and the April 2007 protocol, an independent cost estimate--a top-to- 
bottom, independent estimate that serves to cross-check a cost estimate 
developed by project officials--should be developed as part of the OECM 
review process for major projects when "complexity, risk, cost, or 
other factors create a significant cost exposure for the Department." 
We believe that a review of a major cleanup project, given its level of 
expected spending over the near term, would meet the criteria for 
requiring an independent cost estimate. According to an OECM official, 
OECM has not performed an independent cost estimate for any of EM's 
major cleanup projects, primarily because OECM lacks the resources 
required to perform this type of rigorous estimate for the projects. 
Instead, OECM has taken a less rigorous and less expensive approach in 
its reviews--examining cost estimates generated by the projects but not 
producing a separate estimate for comparison. 

According to DOE officials, it is addressing some of these guidance 
issues. By the end of September 2008, officials told us, DOE plans to 
replace its manual directing implementation of Order 413 with a series 
of 16 guides. The guides are expected to cover a range of project 
management issues, including risk management and contingency funding, 
with one guide providing direction on the management of EM cleanup 
projects. In addition to the guides, as part of an EM-wide effort to 
improve project performance, EM has issued 18 recommended priority 
actions that contain additional EM-specific requirements for cleanup 
projects. It is unclear whether the guides and priority actions are 
expected to supplant all other guidance, or whether they will 
adequately address the challenge project managers face in determining 
the most up-to-date, comprehensive guidance to be followed. 

DOE Recently Changed Expectations for Cleanup Projects' Performance: 

According to EM senior managers, EM cleanup projects are significantly 
different from DOE's construction projects in a number of ways. That 
is, it is harder in many instances to clearly define up-front 
requirements for cleanup projects, and there are more unknowns, 
especially since some of these projects are the first of their kind, 
with undefined scopes of work and significant risks scheduled many 
years into the future. Because of these differences and because it has 
said changing budget priorities may affect funding over time, DOE 
recently changed its performance goal--the amount of work to be 
accomplished and the cost margin for accomplishing that work--for EM 
cleanup projects to reflect a much larger margin of error than the 
performance goal set for construction projects. 

Before 2008, a major cleanup project was measured against the same goal 
as a construction project: achieve at least 100 percent of the scope of 
work in its baseline with less than a 10 percent cost increase over the 
life of the project.[Footnote 37] However, EM's current cleanup project 
performance goal applies only to the near-term baseline, and the 
projects now are considered to be successful if they achieve at least 
80 percent of the scope of work in their near-term baselines with less 
than a 25 percent cost increase. The new performance goal permits up to 
20 percent of the scope of work to be deferred from the near term to 
out years, which creates a substantially greater risk that life cycle 
costs will continue to increase and that completion dates will be 
delayed. As a result, for example, under this goal the four major 
projects each expected to cost more than $2 billion in the near term 
could increase their costs by $500 million each over that period and be 
considered successful. Furthermore, because a directed change--defined 
as a change caused by DOE policy, or regulatory or statutory actions-- 
already exempts projects from meeting the performance goals, creating a 
less stringent goal for EM cleanup projects further waters down the 
impact of having a performance goal in the first place. By lowering 
expectations for adhering to near-term baselines, DOE inadvertently may 
be creating an environment in which large increases to project costs 
become not only more common, but accepted and tolerated. 

DOE Is Undertaking Efforts to Implement Project Management 
Improvements: 

EM is undertaking a number of efforts to improve its project 
performance and address long-standing problems. One such effort is EM's 
"Best-in-Class" Project Management Initiative through which EM 
leadership has committed to improving project performance. Under the 
initiative, EM contracted with the Army Corps to assess the current 
status of project management at EM headquarters and its offices. Using 
the Army Corps' analysis, EM identified a set of challenges it faced in 
executing its mission, which resulted in the creation of the 18 
priority actions for it to undertake to address the challenges and 
implement its initiative. Those priority actions include, among others, 
completing DOE's project management guide, which is expected to bring 
all project management guidance documents under one umbrella document; 
establishing standard reporting formats for project updates produced by 
project managers, including QPRs; implementing new project management 
software packages, including those for EVM analysis; and better 
integrating its project and contract management activities. EM has 
developed a set of implementing steps and a summary of expected 
benefits for each priority action. According to EM, 10 of the priority 
actions are being implemented in fiscal year 2008, and 5 of those are 
scheduled to be completed by the end of that fiscal year. It appears 
that execution of the priority actions would create new tools and 
potentially enhance existing ones in EM's effort to improve its cleanup 
projects' performance. According to EM, full implementation of the 
priority actions will address many EM project management problems and 
deficiencies. However, since the actions are still being implemented, 
it is too soon to determine their effectiveness. 

In addition, EM officials acknowledged that the actions they are 
implementing to improve the management of EM's overall cleanup efforts, 
including their Best-in-Class initiative and actions being taken in 
response to the 2007 National Academy of Public Administration report 
have not been formally documented into a specific, corrective action 
plan that includes performance metrics and completion milestones. These 
officials agreed that such a comprehensive plan would demonstrate a 
more integrated and transparent commitment to improving the management 
of EM's cleanup projects. 

Conclusions: 

Cleaning up the nuclear weapons complex is a technically challenging 
and risky business. Even as DOE works to gain control of and better 
manage its major nuclear waste cleanup projects, cost increases and 
project delays continue to mount. Specifically, life cycle costs for 
EM's major cleanup projects have increased by cumulative $25 billion 
over the past few years and schedules have been extended by a combined 
total of more than 75 years, primarily because DOE had to adjust the 
optimistic baselines it created to accommodate the realities it has 
encountered at its cleanup projects. 

Given the cost and complexity of the major nuclear cleanup projects, it 
is critically important that DOE fully use the tools it has developed-
-independent reviews, performance information systems, guidance, and 
performance goals--to better ensure that projects stay within 
established parameters for scope of work, costs, and schedule. 
Independent baseline reviews to ensure that the work promised can be 
completed on time and for the estimated cost appear to be a useful 
planning tool, but the significant changes that have occurred within 
years or even months of the baseline reviews and validations indicate 
that implementation of these reviews has fallen short. Furthermore, 
EM's site proposals for changes to cost and schedule baselines, 
quarterly performance reports, earned value data analysis and reports, 
and reports to Congress do not consistently provide accurate and 
comprehensive information on the status of projects, which undermines 
managers' and Congress's ability to effectively oversee projects and 
make timely decisions, such as targeting resources to particular 
projects or renegotiating cleanup milestones and other contract 
conditions. These problems are compounded by the lack of comprehensive 
and clear guidance for DOE project managers so that they consistently 
implement DOE management policies across the projects and EM's recently 
relaxed performance goals establishing the acceptable baseline change 
parameters for major cleanup projects. Although DOE has identified a 
number of improvements it intends to make to its project management 
approach, it is still in the early stages of implementing these 
improvements, making it too soon to assess the effort's full effect, 
and it has not yet formally documented all the improvements in a 
comprehensive corrective action plan. 

Recommendations for Executive Action: 

So that DOE can better manage its major cleanup projects and more fully 
inform Congress on the status of these projects, we recommend that the 
Secretary of Energy direct the Assistant Secretary for Environmental 
Management to take the following five actions: 

* Include in its budget request to Congress life cycle baseline cost 
estimate information for each cleanup project, including prior year 
costs, estimated near-term costs, and estimated out-year costs. 

* Develop an approach to regularly inform Congress of progress and 
significant changes in order to improve EM's accountability for 
managing the near-term baseline and tracking life cycle costs. Similar 
to the Department of Defense's Selected Acquisition Reports, which 
include annual information on full life cycle program costs, among 
other things, EM's report, at a minimum should compare estimated near- 
term and life cycle scope, cost, and schedules with the original and 
subsequently updated baselines, and provide a summary analysis of root 
causes for any significant baseline changes. 

* Expand the content of EM performance reports to describe the 
implications of current performance for the project's overall life 
cycle baseline, including the near-term baseline cost and out-year cost 
estimate, using, when appropriate, valid earned value data that conform 
to industry standards and GAO-identified best practices. 

* Consolidate, clarify, and update its guidance for managing cleanup 
projects to reflect (1) current policy regarding independent baseline 
reviews and (2) the results of DOE's determination of the appropriate 
means for calculating and budgeting for contingency so that project 
managers can consistently apply it across nuclear waste cleanup sites. 

* Consolidate all planned and ongoing program improvements, including 
those stemming from the Secretary's contract and project management 
root cause analysis corrective action plan, the Best-in-Class 
initiative, and the 2007 National Academy of Public Administration 
report, into a comprehensive corrective action plan that includes 
performance metrics and completion milestones. 

Because independent baseline reviews have not always provided 
reasonable assurance of the stability of projects' near-term baselines 
or the reasonableness of the life cycle baselines, we recommend that 
the Secretary of Energy direct the Director of the Office of Management 
to take the following action: 

* Assess the Office of Engineering and Construction Management's 
current approach and process for conducting baseline reviews of EM 
cleanup projects to identify and implement improvements that will 
better provide reasonable assurance that project work scope can be 
completed within the baselines' stated cost and schedule. Consider 
including in the assessment process an analysis of past lessons learned 
and reasons for baseline changes, and an assessment of project 
affordability when conducting baseline reviews. 

Agency Comments and Our Evaluation: 

We provided a draft of this report to DOE for its review and comment. 
DOE agreed with our recommendations but provided some suggested changes 
to them, which we incorporated as appropriate. 

In addition, DOE provided some specific comments on our draft report. 
First, DOE stated that the report should provide a more balanced and 
accurate portrayal of EM's cleanup projects by including descriptions 
of ongoing initiatives, a number of which EM launched in recognition of 
the need for improvement, as well as providing better context of the 
challenges and constraints the department's cleanup program faces. The 
draft report included a brief description of EM's ongoing initiatives, 
including its Best-in-Class effort, and acknowledged many of the key 
challenges DOE faces while illustrating the factors contributing to 
changes in scope, cost, and schedule for its cleanup projects. We also 
acknowledged DOE's ongoing initiatives and progress in a 2007 report on 
project management.[Footnote 38] In addition, DOE cited its successes 
in the cleanup of Rocky Flats and Fernald as evidence of its project 
management accomplishments. We commend DOE on its past performance in 
successfully cleaning up these sites, which has resulted in some 
lessons learned that DOE can apply to other cleanup efforts, as we 
reported in 2006.[Footnote 39] Nevertheless, we found in this review 
that DOE has not always effectively used its management tools to help 
oversee the scopes of work, costs, and schedules for its present major 
cleanup projects. 

Second, DOE stated that our draft report appears to confuse the term 
"baseline." It noted that there is only one project baseline--the near- 
term baseline approved by EM senior management--for which DOE should be 
held accountable. Our use of the term "baseline" in this report 
conforms to EM's guidance documents indicating a project's "lifecycle 
baseline" is composed of its prior year, near-term, and out-year costs. 
In addition, we disagree with DOE's assertion that it should be held 
accountable only for a project's near-term baseline. As we state in 
this report, since projects encountering problems have tended to manage 
those problems by moving work scope into the out years, the effects of 
problems occurring today show up as increases to out-year cost and 
schedule estimates and not as increases or delays in a near-term 
baseline. Therefore, if DOE's performance is measured solely on the 
basis of the near-term baseline, potentially significant cost and 
schedule increases would not be accounted for or transparent. 

Third, DOE stated that one of our recommendations--to consolidate, 
clarify, and update its guidance for managing cleanup projects to 
reflect the results of DOE's determination of the appropriate means for 
calculating and budgeting for project contingency--could be more 
specific, and it outlined three contingency options. These options 
include (1) increasing the amount of contingency funding for cleanup 
projects to an 80 percent confidence level, the level budgeted for 
construction projects; (2) creating a general contingency fund 
available for project managers at DOE headquarters to dispense as 
needed to manage project risks; and (3) continuing with the current 
approach of not including contingency funding for cleanup projects in 
its budget requests--funding cleanup projects at the 50 percent 
confidence level--and changing its recently established performance 
goal. We recognize that managing project contingency is an important 
issue, and in fact note in our report that DOE's current approach is a 
likely contributing factor to cost increases and schedule delays for 
EM's major cleanup projects. While we did not specifically assess these 
three options in our report, DOE should continue to study the lessons 
learned from managing and budgeting contingency and select the option 
that would provide contingency funds in an expedient manner to better 
mitigate the impacts of cleanup project changes while minimizing the 
amount of unused contingency funding left over at the end of the fiscal 
year. 

Finally, as part of the explanation of its third option for funding 
project contingency, DOE stated that GAO has agreed to its recently 
established performance goal--to accomplish at least 80 percent of the 
scope of work in the near-term baselines with less than a 25 percent 
cost increase. GAO has not agreed to this goal. As we state in this 
report, we are concerned with DOE's new goal given that it is lower 
than the previous goal for cleanup projects and that DOE may 
inadvertently be creating an environment in which large increases to 
project costs become not only more common, but accepted and tolerated. 

DOE also provided detailed technical comments, which we have 
incorporated into our report as appropriate. DOE's comments are 
reproduced in appendix IV. 

We are sending copies of the report to interested congressional 
committees, the Secretary of Energy, and the Director of the Office of 
Management and Budget. We will make copies available to others on 
request. In addition, the report will also be available at no charge on 
the GAO web site at [hyperlink, http://www.gao.gov].

Appendix I: Scope and Methodology: 

To determine the extent to which the cost, schedule, and scope baseline 
estimates for the Department of Energy (DOE) Office of Environmental 
Management's (EM) cleanup projects have changed and the key reasons for 
these changes, we identified 10 major cleanup projects at 5 DOE sites. 
We first identified 9 major cleanup projects with current near-term 
cost estimates (usually a 5-year period) above $1 billion, the DOE 
threshold for major cleanup projects. In addition, to include those 
projects that could potentially become major projects because of cost 
growth, we reduced the threshold to $900 million and identified another 
project, the Richland nuclear material stabilization and disposition 
project, which is estimated to cost between $900 million and $1 billion 
over the near term. We focused on these 10 major cleanup projects 
because of their significant cost--combined estimated near-term costs 
of about $19 billion and combined life cycle costs estimated at more 
than $100 billion--and because they account for almost half of EM's 
$5.5 billion fiscal year 2009 budget request. (See app. II for 
information on these projects.) 

To identify the factors that may hinder DOE's ability to effectively 
manage these cleanup projects, we spoke with DOE project directors and 
contractor officials and reviewed project management documents for the 
10 major cleanup projects we had identified. We conducted site visits 
to Idaho National Laboratory, Los Alamos National Laboratory, Oak Ridge 
Reservation, Savannah River, and Hanford, and analyzed project 
documentation--contracts, policy directives and memoranda, project 
management plans, DOE's Office of Inspector General reports, 
independent reviews, project execution plans, risk management plans, 
quarterly project reviews, monthly project status reports, earned value 
management (EVM) surveillance plans, and project control documents 
prepared to guide and control formal changes to the baselines. For our 
analysis of projects' scope, cost, and schedule data, we examined the 
initial baselines reported as of the most recent contract award or 
major contract modification (which occurred between 2004 and 2007) and 
compared these baselines with the updated baselines at the time of our 
review. Initial cost baselines are the estimated life cycle costs at 
the beginning of the new contract period for operation of the DOE site 
or associated projects or the major contract modification or extension, 
which typically coincided with the beginning of the projects' current 
or previous near-term baseline. We also calculated the percentages of 
cost increases on the basis of constant 2008 dollars to make them 
comparable across projects and to show real increases in cost while 
excluding increases due to inflation. In addition, because EM now is 
reporting its life cycle cost and schedule estimates as ranges, we 
included these ranges in the report. However, because the upper ends of 
these ranges include unfunded contingency and EM does not include 
funding in its budget requests for this contingency, we report cost 
increases and schedule delays based on the lower ends of the ranges. 

We also analyzed contractor performance data to determine whether DOE 
major cleanup projects are consistently developing and analyzing 
accurate earned value data according to industry standards and best 
practices. We gathered and analyzed data produced by the EVM system 
used for one project at each of the following sites: Idaho National 
Laboratory, Los Alamos National Laboratory, and Hanford.[Footnote 40] 
Often, EVM systems differ depending on how the contractor chooses to 
implement the EVM approach. Because of these differences, we gathered 
and analyzed information on each EVM system on a case-by-case basis, 
according to the structure, reporting format, content, and level of 
detail, among other things, unique to each EVM system. We also 
considered the best practices developed by GAO for estimating and 
managing project costs to analyze the contractor EVM data.[Footnote 41] 

In addition, we spoke with DOE officials from EM and the Office of 
Engineering and Construction Management in Washington, D.C., and with 
representatives from LMI Government Consulting, which conducts external 
independent reviews of the projects for DOE, to obtain their 
perspective on how these projects are managed. 

Because we and others previously have expressed concern about the data 
reliability of a key DOE project management tracking database--the 
Project Assessment and Reporting System--we did not develop conclusions 
or findings based on information generated through that system. 
[Footnote 42] Instead, we collected information directly from project 
site offices and the contractors. 

We provided an interim briefing to the Subcommittee on Energy and Water 
Development, House Committee on Appropriations, on the status of our 
work on April 3, 2008. 

We conducted this performance audit from March 2007 to September 2008 
in accordance with generally accepted government auditing standards. 
Those standards require that we plan and perform the audit to obtain 
sufficient, appropriate evidence to provide a reasonable basis for our 
findings and conclusions based on our audit objectives. We believe that 
the evidence obtained provides a reasonable basis for our findings and 
conclusions based on our audit objectives.

Appendix II: Information on the 10 Department of Energy Major Cleanup 
Projects Reviewed: 

Project: Solid Waste Stabilization and Disposition, Idaho National 
Laboratory, Idaho (PBS 13); 
Project purpose and objective: This project will characterize, treat, 
and ship approximately 64,000 cubic meters of transuranic waste that 
will ultimately be stored in the Waste Isolation Pilot Plant in New 
Mexico. Transuranic waste is radioactive waste containing more than 100 
nanocuries of alpha-emitting transuranic isotopes per gram of waste 
with half-lives greater than 20 years, except for high-level 
radioactive waste. The transuranic waste that must be handled remotely 
through protective shielding, because it emits penetrating radiation, 
will be treated at the Radioactive Waste Management Complex. The 
project also will treat and dispose of a mixed low-level waste backlog 
and handle on-site low-level waste for disposal at the complex. 

Project: Nuclear Facility Decontamination and Decommissioning, Oak 
Ridge Reservation Tennessee (PBS 40); 
Project purpose and objective: The project will decontaminate and 
decommission approximately 500 facilities and remediate 160 sites in 
the East Tennessee Technology Park. This project includes the park's 
two major buildings--the K-25 and K-27 gaseous process buildings--and 
requires the contractor to remove processing equipment and excess 
materials stored in the buildings, demolish building structures, and 
dispose of all associated wastes. 

Project: Nuclear Material Stabilization and Disposition, Savannah River 
Site, South Carolina (PBS 11); 
Project purpose and objective: The project will stabilize and dispose 
of enriched uranium materials and current and projected inventories of 
aluminum-clad spent nuclear fuel in H-Area facilities. It also will 
stabilize and dispose of highly enriched uranium solutions, 
miscellaneous fuels, plutonium residues, enriched uranium residues, and 
other materials DOE identifies that remain from the production of 
nuclear weapons. The project also will deactivate F-Area and H-Area 
facilities; and dispose of special nuclear materials in the K-Area 
Complex. 

Project: Radioactive Liquid Tank Waste Stabilization and Disposition, 
Savannah River Site, South Carolina (PBS 14C); 
Project purpose and objective: The project will remove, treat, and 
dispose of 49 underground storage tanks holding a total of 37 million 
gallons of highly contaminated legacy waste This effort includes 
pretreating radioactive waste such as sludge and salt waste, vitrifying 
sludge and high-level waste at the Savannah River Site's Defense Waste 
Processing Facility, and treating and disposing of low-level saltstone 
waste. 

Project: Soil and Water Remediation, Los Alamos National Laboratory, 
New Mexico; (PBS 30); 
Project purpose and objective: The project will identify, investigate, 
and remediate, when necessary, areas with known or suspected chemical 
and radiological contamination attributable to past Laboratory 
operations. It will investigate and clean up (as needed) approximately 
860 solid waste management units and areas of concern remaining from 
the original 2,129 sites spread over approximately 39 square miles. The 
protection of surface water and groundwater resources that may be 
impacted by these management units and past Laboratory operations also 
are within the scope of this project. 

Project: Nuclear Material Stabilization and Disposition, Hanford, 
Washington (PBS 11); 
Project purpose and objective: The project will stabilize, package, and 
ship (to the Savannah River Site) nuclear materials and fuels used for 
the production of plutonium nitrates, oxides, and metal from 1950 
through 1989 and now stored primarily in vaults in several facilities. 
The project will then clean and demolish the facilities. 

Project: Solid Waste Stabilization and Disposition, Hanford, Washington 
(PBS 13C); 
Project purpose and objective: The project will treat and store spent 
nuclear fuel, transuranic waste, mixed low-level waste, and low-level 
waste generated at the Hanford site and other DOE and Department of 
Defense facilities. It eventually will transfer and ship spent nuclear 
fuel elements and 1,936 cesium and strontium capsules to the proposed 
geologic repository in Nevada. The project also will operate, among 
other things, the (1) Waste Receiving and Processing Facility to 
process transuranic waste and low-level waste and (2) Central Waste 
Complex to store low-level and mixed-low-level waste and transuranic 
waste pending final disposition. 

Project: Soil and Water Remediation, Hanford, Washington (PBS 30); 
Project purpose and objective: The project will remediate contaminated 
groundwater. This effort involves characterizing the movement of 
radionuclides and chemicals (carbon tetrachloride, chromium, technetium-
99, strontium, and uranium plumes); assessing the soil and groundwater 
characterization results; groundwater and risk assessment modeling; and 
operation of groundwater remediation systems among other related 
actions. 

Project: Nuclear Facility Decontamination and Decommissioning at River 
Corridor Closure Project, Hanford, Washington (PBS 41); 
Project purpose and objective: Also known as the River Corridor Closure 
Project, this project will remediate 761 contaminated waste sites at 
the Hanford site near Richland, Washington, and decontaminate, 
decommission and demolish 379 surplus facilities that are adjacent to 
the Columbia River. This project also will dispose of material in the 
Environmental Restoration Disposal Facility. 

Project: Radioactive Liquid Tank Waste Stabilization and Disposition, 
Office of River Protection, Hanford, Washington (PBS 14); 
Project purpose and objective: The project will retrieve, stabilize, 
treat, and dispose of 53 million gallons of radioactive mixed waste 
stored in 177 underground tanks at the Hanford site. The project also 
involves testing and implementing supplemental waste treatment methods; 
operating the Waste Treatment Plant; providing interim storage of 
immobilized waste planned for disposal in an offsite repository; 
receiving and disposing of immobilized low-activity waste on-site in 
near-surface disposal facilities; and closing tanks and tank farm 
facilities.

Mr. Gene Aloise: 
Director of Natural Resources and Environmental: 
U.S. Government Accountability Office: 
441 G Street NW: 
Washington, D.C. 20548: 

Dear Mr. Aloise: 

Thank you for the opportunity to review the draft report on 
accountability and management of the Department's major cleanup 
projects managed by the Department of Energy's Office of Environmental 
Management (EM). We are in agreement with the recommendations you have 
provided, with some suggested changes, and look forward to reporting in 
the future on the progress being made. Detailed comments to the draft 
report are enclosed. Major comments are summarized below. 

We believe the report should provide a more balanced and accurate 
portrayal of EM's cleanup projects by including descriptions of ongoing 
initiatives and actions, a number of which were launched by EM in 
recognition of the need for improvement. Additionally, the report 
should provide better context of the incredible challenges and 
constraints the Department's cleanup program faces and the difficulties 
associated with accurate predictions of project cost and schedule for 
the EM cleanup projects. 

For instance, the Government Accountability Office's (GAO) conclusion 
in 2001 (GAO-01-284, Nuclear Cleanup: Progress Made at Rocky Flats, but 
Closure by 2006 Is Unlikely, and Costs May Increase) states that 
"Kaiser-Hill and DOE are unlikely to meet the December 2006 target 
closure date" for Rocky Flats and yet this closure date was indeed met 
by DOE and the Rocky Flats cleanup contractor Kaiser-Hill. As 
recommended by the GAO in 2006 (GAO-06-352, Nuclear Cleanup of Rocky 
Flats: DOE Can Use Lessons Learned to Improve Oversight of Other Sites' 
Cleanup Activities), EM used the lessons learned from Rocky Flats for 
other cleanup efforts across the complex to accomplish extremely 
successful cleanups. We won the Project Management Institute award for 
our prowess in project management in 2006 and 2007 for the Rocky Flats 
and Fernald cleanup projects, respectively. 

There appears to be some confusion over the term "baseline". There is 
only one project baseline, the near-term baseline that has Critical 
Decision-2 approval by the Acquisition Executive, for which DOE should 
be held accountable. The Decision-1 type range) which is expected to 
change, often by significant amounts. For this very reason, DOE no 
longer expresses lifecycle information on cleanup projects as a point 
estimate. 

Finally, the issue of how we fund and manage project contingency is 
critical to our long-term success and our ability to mitigate impacts 
of these changes. We recognize full well that we cannot continue to 
extend schedules and increase costs every time risks that have been 
identified and anticipated in advance occur. Your fourth 
recommendation, with regard to contingency, could be more specific. 
There are three primary or bounding contingency options as we see it, 
discussed further in the attachment: 

1. Fund operating cleanup project contingency at 80% confidence level 
instead of the current 50%. 
If provided over and above current target levels, approximately $500 
million (M) to $700M additional funding annually would be required. 
However, if risks did not materialize during the budget year, there 
would be higher uncosted year-end carryover. However, to plan for this 
level of contingency without additional funding would require deferral 
of lower priority project scope. To compensate, EM would need to 
renegotiate compliance milestones or possibly subject the federal 
government to fines, penalties, and lawsuits; renegotiate and possibly 
terminate contracts, thus affecting employment; and reprioritize its 
projects. 

2. Request appropriation of a smaller general contingency fund. The 
fund (perhaps $100M to $200M annually) would be held, managed, and 
distributed by the Assistant Secretary for Environmental Management. 
This option would allow more flexibility and expediency in applying 
funds where they are needed as risks are realized, and would allow for 
multi-year business case decision-making. However, controls would need 
to be put in place on EM's allocation authority during execution so as 
not to usurp Congressional authority in appropriations. 

3. Continue the current approach of funding 50% confidence levels and 
changing the corporate metric for the EM cleanup projects agreed to by 
DOE, the Office of Management and Budget (OMB), and GAO. 
This approach budgets for contingency at a 50% confidence level for 
cleanup projects. When risks not covered at this level materialize, 
work scope is shifted to the outyears when funds can be requested in 
light of overall program priorities. A 50% confidence level across the 
EM portfolio connotes that based on statistical analysis half the 
projects would be expected to be completed within the cost and schedule 
and half would not. Thus, this current approach appears to be 
inconsistent with achieving success in the corporate metric that DOE 
has agreed to with GAO and OMB for cleanup projects (established 
through DOE's Root Cause Analysis Corrective Action Plan, July 18, 
2008). The metric requires that 90% of the projects in EM's portfolio 
at the end of the approved near-term baseline period have 80% of the 
scope completed within 25% of the original cost. 

Any GAO recommendations regarding new strategies are welcomed, given 
the regulatory-driven nature and complexity of this work, the 
sensitivity of life-cycle costs to relatively small slippages in scope 
(due to large "hotel" costs), and the need to deliver on commitments 
made to our regulators, the Congress, and other stakeholders. 

Again, thank you for your assistance as we seek to improve our 
management of cleanup projects. We welcome direct dialogue with you on 
these issues prior to finalizing your report. We would also appreciate 
you including the attached comments in the final report. If you have 
any questions with regard to these comments, please contact me on

Footnotes: 

[1] For this review, we lowered the threshold to $900 million out of 
concern that some projects not now considered major would become major 
because of increases in costs, which resulted in the addition of one 
project to our review (the solid waste stabilization and disposition 
project at the Hanford Site, near Richland, Washington). 

[2] We did not review one major project still in the early stages of 
development (the nuclear facility decontamination and decommissioning 
project in Portsmouth, Ohio). 

[3] DOE defines life cycle costs as the sum total cost of the direct, 
indirect, and other related costs incurred or estimated to be incurred 
in the design, development, production, operation, maintenance, 
support, and final disposition of a major system over its anticipated 
useful life span. 

[4] Hanford's radioactive liquid tank waste stabilization and 
disposition project is administered by the Office of River Protection, 
while the other four major cleanup projects at Hanford are administered 
by DOE's Richland office. 

[5] Order 413.3 was issued in 2000 and amended in 2006, and is now 
referred to as 413.3A. For this report, we use DOE Order 413 to refer 
to the order in effect, unless otherwise specified. 

[6] We have reported on DOE's management of these construction 
projects. See GAO, Department of Energy: Major Construction Projects 
Need a Consistent Approach for Assessing Technology Readiness to Help 
Avoid Cost Increases and Delays, [hyperlink, http://www.gao.gov/cgi-
bin/getrpt?GAO-07-336] (Washington, D.C.: Mar. 27, 2007). 

[7] In previous years, DOE presented out-year estimates as a single 
point estimate based on the most probable cost and schedule of its 
projects. In 2007, DOE developed out-year estimates with cost and 
schedule ranges to account for the uncertainty associated with long- 
term projects. The low end of the range is based on the amount of 
funding needed with a 50 percent level of confidence that the project 
will be successfully completed, while the high end of the range is 
based on an 80 percent level of confidence. As discussed elsewhere in 
this report, DOE does not fund its contingency accounts for these 
projects. 

[8] Contingency funds are funds that may be needed to cover potential 
cost increases stemming from a variety of project risks, including 
technical complexities, regulatory issues, and funding shortfalls.

[12] DOE defines a project as a unique effort that supports a program 
mission and that has defined points for starting and ending; is 
undertaken to create a product, facility, or system; and contains 
interdependent activities planned to meet a common objective or 
mission.

Value Management System. The OMB requirements also are reflected in the 
Federal Acquisition Regulation at 48 C.F.R. subpart 34.2. 

[16] EM recently began using schedule estimate ranges rather than point 
estimates. According to EM officials, scheduled completion dates at the 
lower end of the ranges were estimated at the 50 percent level of 
confidence, while dates at the upper end of the ranges represent the 80 
percent level of confidence. For this report, our analysis of schedule 
change uses the lower end of the range.

[18] EM's priority list is based on maximizing risk reduction. As such, 
it has ranked its activities in priority order, from highest to lowest, 
from stabilizing radioactive tank waste in preparation for treatment 
down to decontaminating and decommissioning excess facilities. 

[19] Figures in this paragraph are in current year dollars. 

[20] According to project officials, site conditions also were worse 
than estimated at Hanford's nuclear facilities decontamination and 
decommissioning project at River Corridor, although a baseline change 
proposal for the cost increase for this project had not been filed with 
EM headquarters at time of our review. 

[21] In 2006 we reported on the primary causes of the cost and schedule 
increases at the WTP, some of which echo the issues we found relative 
to the major cleanup projects: shortcomings in the contractor's 
performance, DOE management and oversight problems, and technical 
challenges that were more difficult to address than anticipated. GAO,

Have Lead to Higher Costs, Construction Delays, and Safety Concerns, 
[hyperlink, http://www.gao.gov/cgi-bin/getrpt?GAO-06-602T] (Washington, 
D.C.: Apr. 6, 2006). 

[22] These dates are based on a 50 percent confidence level. With 80 
percent confidence, the liquid tank waste is estimated to extend until 
2050, the solid waste project is estimated to complete in 2058, and the 
soil and water project is estimated to extend until 2059.

30, 2008.) 

[24] As we recently reported, DOE may identify additional nuclear 
materials to process through these facilities, which could delay the 
planned 2019 shutdown and increase operational costs. GAO, Nuclear 
Material: DOE Needs to Take Action to Reduce Risks Before Processing

2005, Pub. L. No. 108-375 § 3116. This law resolved a lawsuit in which 
an environmental group alleged that DOE lacked authority to determine 
that particular wastes were not high-level waste. 

[26] [hyperlink, http://www.gao.gov/cgi-bin/getrpt?GAO-08-793]. 

[27] DOE included $180 million (representing an additional 18 months of 
work) in its unfunded contingency for this project , which would have 
covered only part of the $450 million cost increase or the 4-year 
schedule delay experienced by the project.

http://www.gao.gov/cgi-bin/getrpt?GAO-07-310] (Washington, D.C.: 
January 2007). 

[29] DOE, Root Cause Analysis: Contract and Project Management 
(Washington, D.C., April 2008). 

[30] We conducted limited assessments of EVM data reliability, 
compliance with industry standards or our best practices, and other 
analyses at three of the five EM sites we visited, including data from 
the Hanford site's river corridor cleanup project, Washington; Idaho 
National Laboratory's advanced mixed waste treatment plant subproject 
(within the solid waste stabilization and disposition project), Idaho; 
and Los Alamos National Laboratory's soil and water remediation 
project, New Mexico. 

[31] Specifically, we found elements where the contractor reported 
budgeted and actual costs of work performed without a corresponding 
work schedule. 

[32] OECM has certified that all of the EVM systems used by the 
contractors working on the 10 major cleanup projects are in compliance 
with the American National Standards Institute/Electronic Industries 
Alliance standard except that of the Advanced Mixed Waste Treatment 
Project contractor at Idaho and the major project at the Los Alamos 
National Laboratory. 

[33] Contract start and end dates for the major cleanup projects do not 
match near-term baseline start and end dates. Furthermore, EVM data at 
Los Alamos is reported only against the current fiscal year, not 
against the full contract period or the near-term baseline. 

[34] In commenting on a draft of this report, EM indicated that scope 
deferrals or changes to the near-term baseline must now be formally 
approved by EM management. 

[35] DOE's fiscal year 2009 request for EM includes ranges of life 
cycle costs and completion dates at the site level. 

[36] Major defense acquisition programs are those identified by the 
Department of Defense that require eventual total research, 
development, test, and evaluation expenditures of more than $365 
million or $2.19 billion for procurement in fiscal year 2000 constant 
dollars. 

[37] As previously reported in GAO-07-518, in 2004 DOE began reporting 
performance information for EM cleanup projects against the same goal 
as the line-item construction projects. In late 2005, however, DOE 
switched to reporting performance only for those projects with 
validated cost and schedule baselines.
