Security, Committee on Commerce, Science, and Transportation, U.S.

Why GAO Did This Study: 

In 1992 Congress authorized the U.S. Army Corps of Engineers (Corps) 
to implement the Delaware River deepening project, which would deepen 
the river’s shipping channel from 40 to 45 feet. In 2002 GAO reviewed 
the Corps’ economic analysis of the project, concluding that it 
contained significant limitations. GAO recommended that the Corps 
prepare a comprehensive economic reanalysis, which the Corps completed 
in 2004. GAO was asked to determine the extent to which (1) the 
reanalysis addressed the limitations GAO identified; (2) the reanalysis’
s benefit projections, as updated, reflect current and anticipated 
market and industry conditions; and (3) the Corps has accounted for 
other key issues that could affect the project. GAO reviewed Corps 
project documentation and interviewed federal officials along with 
representatives of affected states, firms, and environmental groups. 

What GAO Found: 

The Corps’ reanalysis addressed many of the limitations GAO had 
identified in 2002 in the Delaware River deepening project’s original 
economic analysis by using updated information to correct invalid 
assumptions and outdated data, recalculating benefits and costs to 
correct miscalculations, and accounting for some of the economic 
uncertainty associated with the project. For example, the Corps 
revised its benefit estimates for transportation cost savings related 
to such commodities as crude oil, containerized cargo, and steel 
slabs. In addition, as GAO recommended, the Corps had independent 
experts review the reanalysis. Although the Corps’ efforts were 
responsive overall to GAO’s 2002 recommendations, GAO identified 
several additional limitations in the reanalysis. For example, in its 
analysis of economic uncertainty, the Corps considered the effects of 
negative-growth scenarios only for crude oil and refined petroleum, 
but not for the remaining commodities. 

In the 6 years that have elapsed since the Corps completed its 
reanalysis, current and anticipated future market and industry 
conditions have changed significantly. Several of the assumptions that 
underlie the Corps’ estimates of the project’s benefits are 
inconsistent with these changes. For example, the Department of Energy 
has lowered its long-term forecasts for growth in East Coast refinery 
capacity and U.S. imports of crude oil. Also, in the fall of 2009, 
Delaware River refinery firms closed two major facilities. Further, 
steel imports have declined since 2006 according to the benefiting 
facility identified in the reanalysis, and were well below the 
reanalysis’s growth projection for 2009. However, the Corps’ 2008 and 
2009 economic updates for the project did not analyze the potential 
effect of these changes on the project’s benefit estimates. The 
updates also did not determine the current status of shipping services 
on two trade routes that provide all of the benefits related to 
containerized cargo. Because of these and other omissions, decision 
makers do not have sufficient updated information to judge the extent 
to which market and industry changes would affect the project’s net 
benefits. 

GAO identified three key outstanding issues that could affect the 
Delaware River deepening project. First, the Corps lowered its 
estimate of the volume of dredged material, which eliminated the need 
for new disposal sites in New Jersey, but its disposal plan continues 
to face resistance from that state. Second, Delaware, New Jersey, and 
several environmental groups filed separate lawsuits against the Corps 
in the fall of 2009, charging that the Corps lacks the environmental 
approvals needed to proceed with the project, among other concerns. 
Finally, New Jersey and several environmental groups have challenged 
in court the Corps’ National Environmental Policy Act (NEPA) process 
for the project. Although the Corps completed an environmental 
assessment (EA) in April 2009, stakeholders believe that the process 
for soliciting public comment on its scope was unclear, did not allow 
enough time for comment, and that a new supplemental environmental 
impact statement is needed. Also, at the Army’s direction, the Corps 
did not provide a public comment period for the draft EA as it had 
proposed to do. 

What GAO Recommends: 

GAO recommends that the Department of Defense direct the Corps to (1) 
provide an assessment of relevant market and industry changes and the 
effect of any changes on the project’s net benefit estimate, and (2) 
develop guidance for public notice and comment on environmental 
documents for projects that are controversial but have no applicable 
NEPA requirement. The Department of Defense generally agreed with 
these recommendations.

The Honorable Frank R. Lautenberg:
Chairman:
Subcommittee on Surface Transportation and Merchant Marine 
Infrastructure, Safety, and Security:
Committee on Commerce, Science, and Transportation: United States 
Senate: 

Dear Mr. Chairman: 

In 1992 Congress authorized the U.S. Army Corps of Engineers (Corps) 
to implement the Delaware River deepening project.[Footnote 1] The 
project would increase the depth of the Delaware River's main shipping 
channel from 40 to 45 feet from the mouth of the Delaware Bay to the 
ports of Philadelphia, Pennsylvania, and Camden, New Jersey, about 100 
miles upriver. The Corps expects this greater depth to facilitate the 
movement of certain commodities--liquid cargo (such as crude oil), 
containerized cargo (such as refrigerated meat), and bulk commodities 
(such as steel slabs and other construction materials)--to receiving 
refineries and other terminals along the river. The deeper channel is 
also expected to reduce the transportation costs for these commodities 
because ships carrying them could travel upriver more fully loaded. 
Specifically, the Corps expects cost savings to occur because oil 
tankers would need less lightering--the practice of unloading a 
portion of a tanker's liquid cargo onto smaller ships in deeper water 
before sailing upriver--and because container and bulk commodity 
vessels could carry the same cargo for lower shipping costs and 
potentially make fewer overall trips from their originating ports to 
their Delaware River destinations. Furthermore, ships that now 
experience delays as they wait for rising tides to allow safe passage 
up the channel could see these tidal delays reduced or eliminated. 

According to project plans, the construction period for the Delaware 
River deepening project is 5 years, followed by annual maintenance 
over a 50-year project operation period. Responsibility for managing 
the project rests with the Philadelphia district office of the Corps' 
North Atlantic division. Following the project's congressional 
authorization in 1992, the Philadelphia district issued a series of 
analyses supporting the deepening, including its 1998 Limited 
Reevaluation Report (LRR), which updated the project's benefits and 
costs. In June 2002[Footnote 2] we reported on material weaknesses in 
the 1998 report's economic analysis of the project's benefits and 
costs. We concluded that the analysis undermined the reliability of 
the Corps' basis for determining whether the project was economically 
justified--that is, whether net benefits exist once project costs are 
subtracted from project benefits. We recommended, among other things, 
that the Corps comprehensively reanalyze the project's benefits and 
costs. 

In response, the Corps reanalyzed the project from 2002 to 2004 
(hereafter referred to as the reanalysis) and concluded that it would 
yield, on average, annual benefits of $24.2 million with annual costs 
of $21.0 million--resulting in annual net benefits totaling $3.2 
million, about $8 million less than the 1998 estimate of annual net 
benefits.[Footnote 3] As in the Corps' 1998 LRR, the reanalysis 
determined that benefits would result largely from transportation cost 
savings associated with importing specific commodities, such as crude 
oil. In addition to the reanalysis, the Corps updated aspects of its 
benefit and cost information in 2008 and 2009. 

The Corps' project plans call for the mud, silt, sand, gravel, and 
rock that would be dredged from the river bottom (dredged material) to 
be stored at federal disposal sites in Delaware and New Jersey; 
blasted rock would be deposited at a federal disposal site in 
Pennsylvania. Through the years, these affected states and regional 
environmental groups have differed in their positions toward the 
deepening project. For example, Pennsylvania has been supportive of 
the deepening, while Delaware, New Jersey, and the environmental 
groups have raised concerns about the disposal of dredged material 
among other aspects of the project. At the time of its reanalysis, the 
Corps envisioned adding three new disposal sites in New Jersey, in 
addition to using existing disposal sites in all three states. 

You asked us to determine (1) the extent to which the Corps' 
reanalysis addressed the economic analysis limitations we identified 
in 2002; (2) the extent to which the benefit projections the Corps 
included in its reanalysis of the project, as updated, are consistent 
with current and anticipated future market and industry conditions; 
and (3) what other key issues, if any, could affect the project, and 
the extent to which the Corps has accounted for these issues and their 
potential impacts. 

To answer the first and third objectives, we developed a list of 
economic limitations and other key issues that we had identified in 
our 2002 report. These issues ranged from errors in benefit and cost 
estimation--such as the misapplication of commodity growth rates and 
the omission of disposal site construction costs--to concerns about 
the Corps' treatment of economic uncertainty, the lack of internal 
quality control in the Corps' report review process, and the Corps' 
analysis of selected environmental topics. We used the economic 
limitations and other key issues we had identified earlier, along with 
standard economic principles, as criteria for reviewing the 2002 and 
2004 reports that form the basis of the Corps' reanalysis to assess 
whether and how each issue was addressed in those documents. In 
addition to the reanalysis, we reviewed later economic and 
environmental analyses the Corps had prepared to determine whether 
certain limitations and other key issues previously identified by GAO 
had been addressed in these subsequent documents. We discussed these 
issues with officials from the Corps' Philadelphia district, its North 
Atlantic division, and its headquarters in Washington, D.C. To answer 
the second objective, we reviewed historical crude oil imports from a 
number of sources, including the Department of Energy's Energy 
Information Administration (EIA). We also reviewed EIA's Annual Energy 
Outlook forecasts for U.S. crude oil imports and refinery capacity on 
the East Coast. We determined that EIA's crude import data and 
forecasts are sufficiently reliable for the purposes of this report. 
(We note that EIA may revise its forecasts over time as new 
information becomes available.) For other commodities, we interviewed 
representatives of importing firms and a U.S. Geological Survey 
official, as appropriate. We also reviewed U.S. government import data 
for additional background. For all three objectives, we consulted 
experts in the fields of economics and lightering, including 
consultants who helped the Philadelphia district prepare its 
reanalysis. We also spoke with representatives of the Delaware River 
refineries, other potential project beneficiaries, and the private 
lightering firm that serves the Delaware River market; representatives 
of the states of Delaware, New Jersey, and Pennsylvania; and 
environmental groups with an interest in the project. Appendix I 
contains more detailed information on our scope and methodology. 

We conducted this performance audit from March 2009 through March 2010 
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. 

Background: 

The Delaware River deepening project calls for dredging the river's 
main navigation ship channel to 45 feet, from a depth of 40 feet, 
beginning at the mouth of the Delaware Bay through Philadelphia 
Harbor, and to the Beckett Street Terminal in Camden, New Jersey--a 
distance of 102.5 miles. The Corps plans to use nine existing federal 
disposal sites in Delaware (one), New Jersey (seven), and Pennsylvania 
(one) to dispose of the material dredged from the bottom of the 
river.[Footnote 4] The new dredged material is to be layered on top of 
the material already deposited at these sites during annual 
maintenance dredging in the channel to maintain its 40-foot depth. 
Additionally, a portion of the material to be dredged is sand from 
Delaware Bay, which would be used by the Corps to restore wetlands at 
Kelly Island, Delaware, and the shoreline at Broadkill Beach, 
Delaware. According to the Corps, dredged material has been used in a 
variety of beneficial projects over the years, including environmental 
restoration, landscaping, and airport runway fill material. Often, the 
material must be drained and dried for several months before it can be 
used in these ways. Figure 1 shows the area to be dredged, the nine 
federal disposal sites, the two Delaware restoration locations, and 
other features discussed in this report.

[End of figure] 

In 1992, the year Congress authorized the deepening project, the Corps 
completed a Final Interim Feasibility Study and Environmental Impact 
Statement (EIS) for the project. This document was used to inform 
decision makers and the public of the Corps' recommended plan for the 
project, potential alternatives to it, its benefits and costs, and the 
likely environmental effects. The Corps then prepared a design 
memorandum in 1996, which provided details on the final design and 
engineering plans for the project, and published a Supplemental 
Environmental Impact Statement (SEIS) in 1997. In its 1998 LRR, the 
Corps updated its economic analysis of the project's benefits and 
costs. 

In our June 2002 report,[Footnote 5] we found that the Corps' 1998 
analysis was based on miscalculations, invalid assumptions, and 
outdated information, and did not consider a number of uncertainties 
that could affect the project's benefits and costs. Consequently, we 
concluded that the Corps' analysis did not provide a reliable basis 
for determining whether the project was economically justified and 
recommended that the Corps (1) prepare a comprehensive, new economic 
analysis of the project; (2) obtain the information necessary to 
address uncertainties that could affect benefits and costs; (3) engage 
an external independent party to review the new analysis; and (4) 
submit the new analysis to Congress. 

In response to our 2002 report, the Corps reanalyzed the economic 
benefits and costs of the deepening project and issued a Comprehensive 
Economic Reanalysis Report in 2002, followed by a Supplement to 
Comprehensive Economic Reanalysis Report in 2004. (In this report we 
use the term "reanalysis" to refer collectively to both the Corps' 
2002 report and 2004 supplement.) The Corps' reanalysis concluded that 
the project would yield average annual benefits of $24.2 million, 
about $16 million less than the Corps' 1998 annual benefit estimate of 
$40.1 million.[Footnote 6] According to the Corps' reanalysis, annual 
benefits would result largely from transportation cost savings 
associated with the importation of specific commodities--crude oil; 
containerized cargo, such as refrigerated meat and produce; and dry 
bulk commodities, such as steel slabs and blast furnace slag (an 
additive used in the production of cement). Crude oil savings would 
account for about half of these benefits, with cost savings related to 
containerized cargo accounting for another quarter of them. See table 
1 for details on the benefit estimates and share of total benefits for 
each benefit category in the reanalysis.

Benefits by Benefit Category for the Delaware River Deepening Project,

[A] Estimates presented at 2002 price levels and federal fiscal year

[End of table] 

The benefit estimates in the Corps' reanalysis depend on a number of 
factors, including (1) the extent to which future growth expands the 
total volume transported for each of the benefiting commodities; (2) 
the savings associated with using less of certain economic resources, 
such as the Delaware River lightering fleet; and (3) the economy's 
prevailing price level and discount rate.[Footnote 7] For the 
reanalysis, the Philadelphia district contracted with a private 
consulting firm to analyze project benefits. 

According to the Corps' reanalysis, the Delaware River deepening 
project would generate benefits relating to commodities imported by 
the following entities: 

* Five crude oil refining facilities with six deep-draft terminals now 
owned by Sunoco (four), Valero (one), and ConocoPhillips (one), with 
four terminals located in Pennsylvania and two in New Jersey.[Footnote 
8] 

* Other commodity terminals, including those at Beckett Street 
Terminal in Camden, New Jersey; Packer Avenue Marine Terminal in 
Philadelphia, Pennsylvania; and Delaware Terminal at the port of 
Wilmington, Delaware.[Footnote 9] 

(The nine commodity terminals appear in the figure 1 map.) 

With regard to project costs, the Corps' reanalysis estimated average 
annual project costs of $21.0 million, almost $8 million less than the 
Corps' 1998 annual cost estimate of $28.8 million. This revised cost 
estimate includes channel dredging, disposal site construction, and 
any related land costs, such as land for new disposal sites and rights 
of way. It also includes associated costs, which are those needed, in 
addition to project costs, to achieve the benefits claimed during the 
period of the Corps' analysis. These costs include, for example, berth 
deepening and dock modifications to accommodate deeper ships at 
refinery facilities and container terminals. Although associated costs 
are the responsibility of the potentially benefiting facilities, the 
Corps includes these costs in its total cost estimate, in accordance 
with its guidance. See appendix II for more information about the 
project's associated costs. 

In addition to the 2002 and 2004 reanalysis documents, the Corps 
prepared the following documents that provide supplemental information 
on the benefits and costs of the Delaware River deepening project: 

* an economic update to the project that reaffirmed the reanalysis's 
benefit and cost estimates for budgeting purposes (April 2008), 

* an environmental assessment that included a section summarizing the 
project's potential economic benefits (April 2009), and: 

* an economic update to support the Corps' fiscal year 2011 budget 
request (December 2009).[Footnote 10]

As of December 2009, the Corps estimated average annual benefits of 
$30.1 million and average annual costs of $22.3 million for the 
project, yielding annual net benefits of $7.8 million. Because 
estimated benefits exceeded estimated costs--resulting in positive net 
benefits and a benefit-cost ratio greater than one--the Corps 
determined that the project remained economically justified. See table 
2 for a summary of the benefit and cost estimates and resulting 
benefit-cost ratios in the Corps' reanalysis and in its most recent 
economic update. As noted in table 2, the benefit and cost estimates 
are based on different price levels and discount rates, which accounts 
for some of the changes observed in the estimates between the 2002-
2004 reanalysis and the 2009 economic update. This means that the 
estimates and resulting net benefits and benefit-cost ratios are not 
directly comparable between the two analyses.

are not directly comparable between the two analyses. 

[End of table] 

With regard to assessing the project's potential environmental 
impacts, the Corps is required to comply with the National 
Environmental Policy Act (NEPA).[Footnote 11] In addition to 
summarizing the project's potential economic benefits, as noted 
earlier, the 2009 environmental assessment's primary purpose was to 
evaluate the impacts of changes to the project and in the project area 
since the 1992 EIS and 1997 SEIS, as well as to present the results of 
post-SEIS environmental monitoring and data collection. 

Although the Corps has made efforts to conduct a reanalysis of the 
project and provide assessments of its potential environmental 
impacts, the project has remained controversial. For many years the 
project has been criticized by regional environmental groups, among 
others, who have raised concerns about the project's impact on water 
quality and various fish and wildlife species, as well as the accuracy 
of the Corps' estimates of the project's benefits and costs. 
Notwithstanding, because of the results of the reanalysis, 
congressional funding, and support for the project from its local 
sponsor and others, the Corps continued its efforts to begin 
construction. Specifically, in 2008 the Philadelphia Regional Port 
Authority (PRPA)--an independent agency of the state of Pennsylvania--
replaced the Delaware River Port Authority as the project's local 
sponsor. In that same year, PRPA and the Army signed a project 
partnership agreement for the construction of the deepening project. 
As the local sponsor, PRPA is to contribute 25 percent of the 
project's total costs.[Footnote 12] 

The Corps' Reanalysis Addressed Many of the Economic Analysis 
Limitations GAO Had Identified in 2002: 

The Corps' reanalysis addressed many of the limitations that we had 
identified in 2002 in the project's original economic analysis by 
using more recent information to correct invalid assumptions and 
outdated data, recalculating benefits and costs to correct 
miscalculations, and accounting for some of the economic uncertainty 
associated with the project. In addition, as we recommended, the Corps 
had independent experts review the reanalysis before submitting it to 
Congress. Although the Corps' efforts were responsive overall to the 
recommendations we made in 2002, we found several additional 
limitations in the reanalysis. For example, in its analysis of the 
economic uncertainty associated with the project, the Corps considered 
the effects of negative-growth scenarios only for crude oil and 
refined petroleum but not for the remaining benefit categories. 

Reanalysis Used Updated Information to Correct Invalid Assumptions and 
Addressed Other Errors: 

The Corps' reanalysis was based in large part on the information that 
its contractor, David Miller & Associates (DMA), an economic 
consulting firm, developed between 2002 and 2004. Using the updated 
information that DMA developed, the Corps revised its list of 
potential benefit categories to exclude those that would no longer 
benefit from the project or those for which the agency had 
insufficient information to calculate benefits. For example, our 2002 
report noted that the Corps had assumed benefits resulting from coal 
and iron ore imports, as well as scrap metal exports, even though 
trade in these commodities had greatly declined since the Corps had 
last studied them. In its reanalysis, the Corps dropped these 
commodities from its benefit calculations because of factors, such as 
reduced trade volumes, that indicated that benefits related to these 
commodities would not be realized. In addition to identifying outdated 
benefit categories, our 2002 report suggested that changing import 
patterns could present new commodities for the Corps' consideration. 
The Corps' reanalysis subsequently identified additional benefiting 
commodities that were not previously considered, such as refined 
petroleum, steel slabs, and blast furnace slag. 

The Corps' reanalysis also prepared new forecasts of growth rates for 
each of the benefiting commodities to correct the past overstatement 
of key benefit categories, using information from government and 
private trade databases to re-evaluate import growth rates. For 
example, in 2002 we found that the Corps' 1998 LRR had applied a 5.8 
percent growth rate to oil imports from West Africa for 1992 through 
2005, when that rate should have been applied only through 2000 and a 
lower rate--1.4 percent--applied for 2001 through 2005. This 
misapplication of growth rates was significant because crude oil 
benefits increase as import volume increases, generating savings from 
reduced transportation costs per barrel. For the reanalysis, the Corps 
assumed a lower annual growth rate of 0.2 percent by linking the 
forecast to the expected growth rate for the Delaware River 
refineries' relatively fixed overall capacity, which was expected to 
grow by 10 percent--or 0.2 percent per year--over the 50-year life of 
the project. For other commodities, the Corps assumed that growth 
would be limited to the period leading up to the base year, which is 
the first year that the project's full benefits can be realized. 
[Footnote 13] One commodity that the Corps limited in this way was 
containerized cargo, which, like crude oil, was assigned growth rates 
in the 1998 LRR that we found in 2002 to be overstated. In addition to 
constraining containerized cargo growth to the period leading up to 
the base year, the Corps' reanalysis also assumed that project 
benefits for containerized cargo would be limited to two specific 
trade routes and the Corps forecasted growth for only one of these two 
routes. These routes included one extending from the East Coast of 
South America northbound to the U.S. East Coast and a second reaching 
from Australia and New Zealand eastbound through the Panama Canal and 
up the U.S. East Coast--both terminating at Philadelphia's Packer 
Avenue Marine Terminal. 

In its reanalysis the Corps also corrected several additional invalid 
assumptions that we had identified in our prior report concerning the 
estimate of crude oil benefits. Specifically, in 2002 we reported that 
the Corps' 1998 LRR (1) assumed that many more crude oil ship type and 
trade route combinations would benefit from a deepened channel than 
could be supported by its analysis, (2) relied on outdated 
specifications for lightering vessels in calculating benefits, and (3) 
incorrectly assumed that lightering reduction benefits would be 
realized at ports of origin. In the reanalysis these issues were 
addressed as follows: 

* First, according to the Corps' original statistical model, in 23 
percent of all possible cases, ships on specific crude oil trade 
routes would carry enough cargo to exceed 40 feet of draft if a 45-
foot channel were available, leading to transportation cost savings 
for that cargo in a deeper channel. However, in its 1998 LRR the Corps 
applied these benefits for 100 percent of the possible ship type-trade 
route combinations, thereby overstating benefits. In the reanalysis, 
DMA replaced the Corps' statistical model with new projections based 
on the characteristics of the ships that actually called on Delaware 
River refineries in 2000, including information on each ship's origin 
and destination, operating cost, crude oil tonnage, actual draft, and 
maximum draft for which it was designed. DMA used this information, in 
conjunction with refinery interviews, to determine which ships would 
be likely to increase their tonnage--and thus their drafts--in a 
deepened channel, and what level of benefits would be associated with 
this change. DMA ultimately based its projections on 86 percent of the 
crude oil tonnage reported by the refineries for the year 2000 because 
the remaining data were incomplete or otherwise unsuitable for 
analysis. 

* Second, for those crude oil tankers that would need to be lightered 
less in a deepened channel, the 1998 LRR relied on outdated 
specifications in assuming that tankers can discharge crude oil into 
refineries' dockside storage tanks twice as fast as they can transfer 
the oil to lightering vessels. The Corps' reanalysis revised this 
assumption to reflect that lightering rates exceed dockside discharge 
rates because of, for example, shorter pumping distances and the 
assistance of gravity when pumping from large tankers to smaller 
lightering vessels. As the Corps recognized in the reanalysis, some 
portion of the benefits of reduced lightering would be offset by the 
increased time and cost of discharging more cargo at refineries' docks. 

* Third, the Corps' 1998 analysis assumed that cost savings from 
reduced lightering would be realized at both the port of origin and 
port of destination. In fact, these benefits would be realized only at 
the destination port because that is where lightering occurs. The 
reanalysis assigns these benefits only to destination ports. 

In the reanalysis, the Corps used a lightering model based on a full 
year's worth of lightering operations data to help refine its estimate 
of crude oil benefits. DMA initially constructed this model using 
assumptions about the lightering firm's practices that were based on 
its review of Maritime Exchange data on tanker movements and sailing 
drafts for the year 2000. Following publication of the model's 
assumptions and results in the Corps' 2002 Comprehensive Economic 
Reanalysis Report, the lightering firm disagreed with DMA's 
methodology and claimed that DMA's assumptions resulted in an 
overstatement of lightering costs, which in turn would overstate crude 
oil benefits derived from avoiding these costs. For example, the 
lightering firm noted that DMA did not include the minority of its 
lightering activity that occurs not in the Delaware River but in the 
ocean offshore of Delaware Bay. Ignoring this portion of the firm's 
lightering overstates cost per barrel lightered by inaccurately 
dividing 100 percent of costs by less than 100 percent of barrels 
lightered. In response, DMA revised its lightering model in the 2004 
supplement by collecting and combining actual lightering operations 
data for the year 2000 from the lightering firm, the Corps' Waterborne 
Commerce Statistics Center, and three of the five principal refinery 
firms operating in the Delaware River at that time. According to the 
Corps, this refinement allowed DMA to account for nearly 99 percent of 
all crude oil barrels lightered in the Delaware River and offshore 
during 2000, providing a more accurate estimate of crude oil benefits 
in the 2004 supplement. 

The Corps further attempted to address the lightering firm's comments 
about its 2002 report by developing a more sophisticated model of 
lightering activities in the event of a 45-foot channel. Specifically, 
in its initial model, DMA had determined that the likely reduction in 
lightering volume in a deeper channel would be roughly equivalent to 
the capacity of one of the three vessels in the lightering firm's 
fleet. DMA estimated lightering reduction benefits by removing that 
vessel and its operating costs from the fleet, as it assumed the 
lightering firm would choose to do in the event of a deepened channel, 
then recalculating total lightering costs based on the remaining two 
vessels. In response to the lightering firm's criticism of this 
approach as unrealistic, DMA revised its approach by using updated 
data on operations from 2000 to simulate tanker-by-tanker lightering 
operations through 2058. The simulation results were matched with 
estimated vessel operating costs and hourly fuel consumption costs 
developed by the Corps' Institute for Water Resources specifically for 
each of the three vessels in the lightering firm's fleet.[Footnote 14] 
According to the Corps, this approach allowed the agency to more 
directly calculate the reduction in total economic resources--such as 
those devoted to each ship's crew, fuel, and maintenance--needed to 
provide lightering services as lightering volumes fall. The Corps 
assumed these freed resources would be put to productive use by the 
lightering firm elsewhere in the economy. The revised methodology in 
the 2004 supplement was associated with a roughly 20 percent drop in 
the Corps' crude oil benefit estimate when compared to the 2002 report. 

Finally, the Corps corrected miscalculations and important omissions 
we identified in 2002 that affected the project's benefit and cost 
estimates. For example: 

* When we attempted to replicate the Corps' results in 2002, we 
identified a $4.7 million gap between the Corps' estimate of annual 
project benefits and the estimate that we developed. The Corps' 
economist for the project told us in 2002 that the gap resulted from a 
computer error that could have occurred when files were transferred 
from one program to another; ultimately, the Corps acknowledged the 
error but was unable to definitively explain it. For the reanalysis, 
the Corps recalculated its total benefit estimate using DMA's new 
analysis of each benefiting commodity. We reviewed this calculation 
and found no significant errors. 

* The Corps' 1998 LRR was marked by inconsistent discounting of 
project benefits and costs to determine their net present value. 
Moreover, the Corps presented benefit estimates at price levels for 
different years--for example, coal benefits were presented at 1991 
price levels and containerized cargo benefits at 1995 price levels. 
Both of these practices made it difficult for decision makers to 
understand and compare the true benefits and costs of the project. In 
developing the reanalysis the Corps used DMA's analysis, which 
standardized the price level and discounting adjustments for project 
benefit estimates by benefit category, presenting each at 2002 price 
levels and using the prevailing discount rate at the time the 
reanalysis was published (5.625 percent). The Corps adjusted the 
reanalysis's cost estimates using the same approach. 

* In 2002 we found that the Corps omitted construction costs for 
federal disposal sites from its summary calculations in the 1998 LRR 
cost estimate. These construction costs would be incurred as the Corps 
expands the sites to accommodate additional dredged material resulting 
from annual maintenance of the 45-foot channel over its 50-year 
project life. In its reanalysis, the Corps' estimate of total costs 
included costs for these sites. 

* In 2002 we reported that the Corps' 1998 LRR failed to update its 
estimates for associated costs, such as deepening the access channels 
that connect the main channel to benefiting facilities' loading docks 
and increasing on-site storage capacity to handle larger deliveries. 
For the reanalysis, DMA hired a subcontractor to survey potentially 
benefiting firms and determine their likely associated costs, 
including berth deepening, dock modifications, and additional storage, 
and to estimate the cost of these modifications. This work was 
completed in 2002, and the Corps included the updated associated costs 
in the reanalysis's total cost estimate. 

* Our 2002 report noted that the Corps' cost estimate in the 1998 LRR 
assumed that annual maintenance dredging for the 45-foot channel would 
begin after the last year of construction and continue for 50 years. 
However, maintenance dredging in completed segments of the channel 
could be required before the end of project construction--a 
consideration that was not accurately incorporated into the Corps' 
previous maintenance cost estimate. The Corps' reanalysis recognized 
that maintaining a 45-foot channel segment is more costly than 
maintaining a 40-foot segment, and incorporated this higher cost into 
its total cost estimate. 

Reanalysis Included Sensitivity Analysis to Assess Uncertainty in 
Benefit and Cost Assumptions: 

In our 2002 report, we observed that some of the errors we identified 
illustrated the uncertainty inherent in forecasting information, such 
as commodity shipments, technological changes, and industry's economic 
choices. We suggested that a reanalysis of the project consider a more 
careful treatment of the uncertainty associated with estimating 
benefits and costs, particularly since Corps guidance requires 
planners to identify areas of uncertainty in their analysis and to 
clearly describe them so that decision makers can understand the 
degree of reliability in a project's benefit and cost estimates. 

One way to analyze the uncertainty associated with estimating benefits 
and costs is to include more information than simple point estimates, 
which can give the illusion of precision when a range of estimates may 
be more appropriate. Sensitivity analysis is one analytical tool for 
assessing the uncertainty associated with the estimates. In the 
context of benefit and cost estimation, sensitivity analysis can be 
used to assess the degree to which a benefit or cost estimate is 
affected by a change in a key assumption. For example, a sensitivity 
analysis for a labor-intensive construction project might examine the 
effect on overall project cost if the estimated hourly cost of labor 
were varied by plus or minus 10 percent. 

The 1998 LRR did not employ sensitivity analysis, but both of the 
reports that constitute the Corps' reanalysis used this tool to 
analyze some of the uncertainties associated with the project's 
benefit and cost estimates. Specifically, in the 2002 Comprehensive 
Economic Reanalysis Report, the Corps used sensitivity analysis to 
assess the extent to which the benefit and cost estimates, including 
the net benefit estimate, would change given alternative assumptions 
about factors such as commodity growth rates, lightering operation 
costs, and future ship sizes for slag and steel imports. For example, 
the Corps analyzed the effect on the net benefit estimate if future 
crude oil imports to Delaware River refineries grew by more, or less, 
than the assumed 0.2 percent per year. Scenarios included higher 
growth, lower growth, no growth, and negative growth.[Footnote 15] 
Under the latter scenario, the Corps estimated that crude oil benefits 
would be reduced by about 16 percent. The Corps' rationale for the 
negative-growth scenario, in part, was the possibility that one or 
more of the refineries could go out of business. The Corps, however, 
stated that this was unlikely, citing the continued expansion of 
demand for products refined from crude oil and noting that its 0.2 
percent growth rate was conservative relative to the Department of 
Energy's projection of future U.S. crude oil imports through 2020, 
which ranged from 0.6 percent to 1.6 percent annually. Similarly, the 
Corps examined the potential effect on benefits of a negative-growth 
scenario for refined petroleum, as well as higher-growth, lower-
growth, and no-growth scenarios for refined petroleum, blast furnace 
slag, containerized cargo, and steel slabs. 

To augment its sensitivity analysis, the Corps examined the 
vulnerability of various benefit categories to the actions of 
individual firms whose business decisions could affect the project. 
For example, the Corps' estimate of blast furnace slag benefits was 
based on slag imports by a single cement firm. Benefits related to 
importing blast furnace slag could be lower or could disappear if this 
facility were to operate at a lower production capacity than the Corps 
assumed, or if it were shut down and not replaced by another firm. 
Crude oil, on the other hand, was imported by five firms at the time 
of the reanalysis's 2002 report. Given the history of the continued 
operation of their respective refinery facilities in the recent past, 
including successful transfers of ownership to new firms, the Corps 
considered it unlikely that any refinery would be shut down for an 
extended period of time. However, the Corps did note that if one or 
more of the refineries went out of business, the benefits related to 
crude oil imports could drop significantly. 

In addition to analyzing the uncertainty associated with some of its 
benefit estimates, the Corps conducted a sensitivity analysis of some 
cost assumptions in the 2002 Comprehensive Economic Reanalysis Report. 
These sensitivity analyses tested different assumptions about key cost 
factors, such as dredging efficiency and the composition of dredged 
material. The latter could vary from mud and silt, which is relatively 
more expensive to dredge, to loose sand, which is relatively cheaper. 
The Corps also examined associated costs--specifically, whether 
individual firms were likely to make the necessary infrastructure 
investments to benefit from a deepened channel given their expected 
benefits. The Corps' analysis showed that facility benefits would 
likely exceed facility costs for each of the project beneficiaries. 

The 2004 Supplement to Comprehensive Economic Reanalysis Report also 
contained sensitivity analyses--four related to crude oil benefits and 
three related to containerized cargo benefits. The crude oil analyses 
examined the impact of altering certain assumptions about lightering 
operations. These assumptions informed the Corps' lightering 
simulation model, such as the vessel capacity assigned to each 
lightering trip in the model, and therefore any change in these 
assumptions could result in a significant change in the Corps' crude 
oil benefit estimate. The final three sensitivity analyses examined 
containerized cargo assumptions. For example, the Corps calculated the 
positive and negative effect on project benefits that would result 
from increasing and decreasing containerized imports by 20 percent, 
respectively, for the two trade routes that the reanalysis identified 
as benefiting from a deeper channel. 

Independent Experts Reviewed the Corps' Reanalysis: 

As we recommended in our 2002 report, the Corps submitted its 
reanalysis to independent reviewers before delivering it to Congress. 
This process included separate reviews of project benefits and costs. 
Benefits were reviewed first by a university professor with expertise 
in transportation systems. In addition, at the request of Corps 
headquarters, the Corps' Institute for Water Resources arranged to 
have an external independent panel review the project's benefit 
analysis. The institute contracted with a private consulting firm to 
convene a panel of economics and navigation experts for this review, 
which consisted of an iterative process of issue resolution through 
panel comments and the Corps' responses. Similarly, the Corps selected 
an engineering firm with expertise in dredging cost analysis to review 
the project's costs, including those incurred in initial construction 
dredging, long-term maintenance dredging, and the construction of 
disposal sites for dredged material. After the independent reviewers 
issued their final reports, the Corps' Director of Civil Works 
approved the reanalysis. 

In at least one instance, the Corps' external independent reviews 
resulted in a substantial change to the project's benefit estimate. 
Specifically, the benefits review panel disagreed with an aspect of 
the approach DMA used to calculate the cost of crude oil lightering 
operations. This calculation had a direct effect on project benefits 
because a significant portion of crude oil benefits are derived from 
avoiding the cost of some lightering due to a deepened river channel. 
DMA defended its methodology in a series of responses to review panel 
comments. However, the Corps ultimately accepted the review panel's 
revision of DMA's calculation and used the resulting lower benefit 
estimate in its 2004 supplement. This $2.8 million adjustment 
represented a 19 percent reduction in annual crude oil benefits and a 
10 percent reduction in the project's total benefit estimate. 

Reanalysis Contained Several Additional Limitations: 

Overall, while the Corps' efforts have been responsive to the 
recommendations we made in 2002, we identified several limitations in 
the economic reanalysis that introduce additional uncertainty into the 
project's benefit estimates. First, the external independent panel 
convened to review the reanalysis's benefit estimates raised concerns 
about the benefit analysis for containerized cargo that may not have 
been fully resolved. Specifically, in its January 2004 final report, 
the independent panel concluded that the Corps had not eliminated 
significant uncertainties associated with the estimation of 
containerized cargo benefits. The review panel had been concerned that 
the Corps based its benefit estimate on transportation cost savings 
that would accrue to the project through more direct delivery of goods 
to Philadelphia-area destinations on just the two trade routes in the 
Corps' analysis--one originating from South America and the other from 
Australia/New Zealand--and a weekly shipping service operating on 
each. According to the Corps, savings would result because some 
containers on the South America route were being shipped to the deeper 
port of New York/New Jersey to bypass the 40-foot Delaware River 
channel, and then trucked south to Philadelphia-area destinations. 
With the deeper channel, the Corps projected that these containers--as 
well as others resulting from growth on the Australia/New Zealand 
route--would instead be shipped directly to the port of Philadelphia 
through the 45-foot channel, avoiding the costly trucking from New 
York/New Jersey to Philadelphia. The review panel noted that for one 
of the two trade routes--Australia/New Zealand to the U.S. East Coast, 
accounting for 85 percent of containerized cargo benefits--the Corps' 
benefit estimate relies on trucking that (1) does not yet occur and 
(2) depends on future revisions to the existing shipping service 
prompted by growth. The panel also noted that the prospective benefits 
rely on the future business decisions of only a few shipping services. 
For these and other reasons, the review panel stated that significant 
uncertainties remained in the containerized cargo benefit estimate and 
that the estimation of benefits accruing to the Australia/New Zealand 
trade route was the greatest source of residual uncertainty for this 
benefit category. The Philadelphia district responded to the panel's 
comments in a document defending its analysis and also revised its 
discussion of containerized cargo benefits in the final version of the 
February 2004 supplement. The district's response was reviewed by 
Corps headquarters, which acknowledged that not all uncertainties had 
been resolved, but concluded that the findings as a whole were 
reasonable and defensible. However, the Corps did not provide the 
final version of the 2004 supplement to the external review panel for 
resolution as the contract for its services had expired. 

Second, as noted earlier, the Corps' 2002 Comprehensive Economic 
Reanalysis Report employed sensitivity analysis to examine the effect 
of negative-growth scenarios on the annual benefit estimates for crude 
oil and refined petroleum. However, negative-growth scenarios were not 
considered for the remaining benefiting commodities, which were 
analyzed under only higher-growth, lower-growth, and no-growth 
scenarios. The possibility of a contraction in the market for blast 
furnace slag, containerized cargo, and steel slabs was not 
insignificant, given the relatively few importers for certain 
commodities and the sensitivity of these markets to changes in world 
economic conditions. Indeed, as noted earlier, estimated benefits for 
slag rely on the future business decisions of a single firm. 
Considering that even a no-growth scenario for each benefit category 
would collectively result in the project's total annual costs slightly 
exceeding its total annual benefits, as shown in the Corps' 
reanalysis, the cumulative effect of negative growth for all 
commodities could have provided additional context to decision makers. 
In addition, the alternative-growth scenarios for crude oil from the 
2002 report's sensitivity analysis were not reanalyzed in the 2004 
supplement, even though the methodology used to develop the estimate 
of crude oil benefits changed substantively from the 2002 report and 
the estimate itself declined by about 20 percent. 

Finally, the lightering firm disagrees with the reanalysis's 
assumption that significant savings will result from the firm reducing 
its service levels proportionally in response to reduced demand for 
lightering in a deepened channel. To the extent that lightering 
service levels in a 45-foot channel are higher than the Corps assumes, 
project benefits could be reduced. In practice, the Corps' assumption 
would mean that the lightering firm's three vessels would spend less 
time in operation, or perhaps that two vessels would maintain similar 
service levels but the third vessel would be put to other uses. This 
reduction in service would save crew, fuel, and other resource costs 
that are the basis for the Corps' estimate of lightering cost savings 
in its crude oil benefit model. However, the lightering firm contends 
that tanker arrivals into Delaware Bay can be unpredictable, with 
multiple arrivals possible on short notice, which requires the firm to 
retain three vessels in order to maintain the flexibility needed to 
provide prompt service. For the importing refineries that pay for 
tankers to ferry crude oil across the ocean to their facilities, 
lightering delays in the bay are costly. Moreover, refinery facilities 
typically do not maintain much on-site storage and instead rely on 
timely deliveries to continue operating. For these reasons, the 
lightering firm told us that the reanalysis's assumption of service 
levels falling in proportion to reduced lightering demand is 
unrealistic. Instead, the lightering firm believes service levels 
would likely remain higher than the Corps' modeling predicts because, 
for example, the firm would continue to provide service with three 
vessels instead of two. In fact, the lightering firm's position on the 
feasibility of reduced service levels resembles an observation that 
the Corps made in discussing the undesirability of delivery delays for 
containerized cargo in the reanalysis's 2002 report: "The issue is 
customer satisfaction and the potential loss of customers who are not 
receiving their desired service." In interviews with us, Corps 
officials characterized their assumption of reduced lightering service 
levels as consistent with an economically rational firm's most 
efficient allocation of its resources. 

The Benefit Assumptions in the Corps' Reanalysis and Economic Updates 
Do Not Fully Reflect Current and Anticipated Future Market and 
Industry Conditions: 

In the 6 years that have elapsed since the Corps completed its 
reanalysis, current and anticipated future market and industry 
conditions have changed significantly. Several of the assumptions that 
underlie the Corps' estimates of the project's benefits are 
inconsistent with these changes. For example, the Department of Energy 
has lowered its long-term forecasts for growth in East Coast refinery 
capacity and U.S. imports of crude oil. These developments raise 
questions about the extent to which the reanalysis's findings could be 
affected by these changed conditions. The Corps' 2008 and 2009 
economic updates did not analyze the potential effect of these changes 
on the project's benefit estimates. Consequently, decision makers do 
not have the updated information necessary to indicate whether the 
market and industry changes that have occurred would affect the 
project's net benefits. 

Reanalysis's Benefit Assumptions Do Not Consistently Reflect Current 
Market and Industry Conditions and Future Outlook: 

Benefits related to crude oil, containerized cargo, and steel slabs 
make up 89 percent of the project's total annual benefits, accounting 
for 49 percent, 25 percent, and 15 percent respectively.[Footnote 16] 
Current market and industry conditions and future outlook for these 
key benefit categories have changed since the reanalysis was completed 
in early 2004. These changes indicate that the assumptions underlying 
the Corps' benefit estimates may need to be revised, but their net 
effect is unclear without additional information and analysis. The 
following summarizes our findings related to these benefit categories, 
in descending order of importance to the project's overall benefit 
estimate. 

Crude Oil: 

The reanalysis's crude oil benefit assumptions are not consistent with 
current market and industry conditions and future outlook, which 
raises questions about the reliability of the reanalysis's crude oil 
benefit estimate. Relevant changes that could affect crude oil 
benefits include a projected decline in refinery capacity, a current 
and projected decline in crude oil imports, and changes in the 
Delaware River crude oil refining and lightering industries. 

Projected Decline in Refinery Capacity: 

In the reanalysis, the Corps chose a 0.2 percent annual growth rate as 
the basis for its long-term forecast for crude oil imports into 
Delaware River ports. The Corps based its growth rate on the expected 
growth in long-term capacity for refineries in the East Coast region. 
This forecast came from the Department of Energy's Energy Information 
Administration (EIA) as part of its Annual Energy Outlook.[Footnote 
17] However EIA's long-term outlook for East Coast refinery capacity 
has declined from 0.2 percent annual growth in its 2002 outlook to a 
0.1 percent annual decline in its 2009 outlook, and the early-release 
version of EIA's 2010 outlook has predicted a steeper decline of 2.0 
percent annually. 

Current and Projected Decline in Imports: 

The Corps observed in its reanalysis that its 0.2 percent annual 
growth rate for crude oil imports was a conservative projection 
compared to a Department of Energy forecast of future U.S. crude oil 
imports through 2020, which ranged from 0.6 percent to 1.6 percent 
annual growth; in its 2002 annual energy outlook, EIA identified 1.1 
percent annual growth in imports as the most likely rate for this 
period. By 2009, this outlook had changed considerably from the 
earlier part of the decade: instead of the 1.1 percent annual growth 
for crude oil imports forecasted in EIA's 2002 long-term outlook or 
the 0.2 percent annual growth assumed by the Corps, EIA's 2009 and 
2010 long-term outlooks forecasted annual declines of 1.6 and 0.4 
percent, respectively. 

Moreover, to date, available data indicate that even the Corps' 
marginal growth rate of 0.2 percent overstated crude oil imports 
through at least 2008. According to EIA data, the volume of crude oil 
imports into Delaware River ports declined from about 415 million 
barrels in 2000 to about 381 million barrels in 2008, for an annual 
decline of 1.1 percent and an overall decline of 8.1 percent since 
2000. Imports were about 332 million barrels in 2009.[Footnote 18] 

We identified several reasons for the decline in crude oil imports 
into the Delaware River and changes to their long-term outlook. First, 
EIA officials pointed to several factors that have reduced the demand 
for crude oil in the United States overall and thus contributed to 
changes in the long-term forecast. These include the requirements of 
new regulations and legislation, such as the Energy Independence and 
Security Act of 2007[Footnote 19]--which includes mandates to increase 
domestic use of nonpetroleum liquid fuels such as ethanol and more 
stringent fuel efficiency standards--and competition from gasoline 
produced in Europe. EIA officials explained that crude oil imports are 
sensitive to changes in the market for gasoline, a product that 
accounts for about half of the refined output from a typical barrel of 
crude oil. East Coast refineries are especially vulnerable to 
competition from refineries in Europe (as well as U.S. Gulf Coast 
states) because the East Coast refineries have relatively high 
production costs. On the other hand, the officials noted that by 
lowering lightering costs, a deeper channel could reduce the cost of 
production and could potentially improve the refineries' position in a 
highly competitive market. 

Second, EIA officials explained that the nation's current economic 
recession has been associated with declines in demand for products 
refined from crude oil and shrinking profit margins for Delaware River 
refineries. These conditions are reflected in relatively low 
utilizations--that is, how much of a refinery's total productive 
capacity is being used--which EIA officials said had fallen below 80 
percent by late 2009. The officials noted that the following two 
Delaware River refinery firms have recently reduced their respective 
refinery capacities by halting production at major facilities: 

* In October 2009 Sunoco announced that it was indefinitely idling its 
Eagle Point refinery facility in Westville, New Jersey. Subsequently, 
the firm announced in February 2010 that the closure was permanent. 

* In November 2009 Valero announced that it would permanently shut 
down one of its two Delaware River refinery facilities--the former 
Motiva facility in Delaware City, Delaware.[Footnote 20] 

According to EIA officials, the remaining Delaware River facilities 
are likely to continue to operate because most of the excess refinery 
capacity has already been squeezed out of the Delaware River region. 
Looking ahead, EIA officials said that according to many observers, 
demand is not expected to return to its former levels even after the 
economy recovers because of the policy and structural changes noted 
earlier, resulting in less need for gasoline from crude oil. However, 
they said that the Northeast will remain a major consumer of home 
heating oil, which is made from crude oil, and that demand will likely 
grow for diesel fuel, a crude oil product that is used heavily in the 
trucking industry--especially in the Northeast. 

Third, according to an independent economic expert with experience 
analyzing the Delaware River crude oil market, demand for crude oil 
imports has declined in the Northeast because of high oil prices, 
changing consumer preferences, and gasoline imports from Europe. He 
predicted that, in general, U.S. energy demand will rely less heavily 
on crude oil in the future. In his assessment, the Corps' crude oil 
forecasts are therefore likely outdated, and while the Corps' 
assumptions about projected crude oil growth may have been reasonable 
in the early 2000s, they do not reflect current and expected future 
conditions. 

Changes in Delaware River Refining Industry: 

Changes in the Delaware River crude oil refining industry affect the 
reanalysis's crude oil benefit assumptions in ways that raise 
questions about the Corps' crude oil benefit estimate. For example, 
the reanalysis's lightering simulation model predicted that in the 
first year of a 45-foot channel the recently closed Eagle Point 
facility's lightering requirement would be reduced by 41 percent. This 
amount represented 22 percent of the total expected decline in the 
need for Delaware River lightering in the model's initial year. This 
reduction in lightering represents resource cost savings that are a 
key part of the Corps' crude oil benefit estimate. If the facility is 
not reopened, it is unclear to what extent its share of crude oil 
benefits would instead be realized by Sunoco's remaining Delaware 
River facilities. In comparison with Sunoco's Eagle Point closure, 
Valero's closure of its Delaware City facility would likely affect the 
crude oil benefit estimate less because this facility was not 
considered a potential beneficiary in the Corps' reanalysis.[Footnote 
21] However, the Corps' lightering simulation model assumed that the 
facility would account for nearly a quarter of the lightering firm's 
volume in the first year of a 45-foot channel. While this 
consideration does not affect the crude oil benefit estimate directly--
because the volume of lightering for this facility was expected to 
remain the same in a 45-foot channel, thus precluding lightering 
reduction benefits--it does alter the assumptions about the lightering 
firm's day-to-day operations that the Corps used to build the model, 
which could affect the benefit estimates for other facilities. 
[Footnote 22] In addition, because the Corps' crude oil benefit 
estimate includes time savings from fewer tidal delays as tankers 
proceed upriver, a reduction in future oil imports could decrease 
these savings in a 45-foot channel. Overall, the net effect of these 
and other industry changes on the Corps' crude oil benefit estimate is 
unclear. 

Changes in Delaware River Lightering Operations: 

Changes experienced by the lightering firm whose operations were 
modeled in the Corps' reanalysis also could influence the Corps' 
estimate of crude oil benefits. According to Overseas Shipholding 
Group (OSG),[Footnote 23] the firm lightered about 98 million barrels 
in 2000, the year that the Corps used to build the reanalysis's crude 
oil benefit model and that served as the basis for its crude oil 
projections. As recently as 2007, OSG officials told us, the firm 
lightered about 95 million barrels; however, OSG lightered only about 
88 million barrels in 2008 and 77 million barrels in 2009, down almost 
22 percent from the 2000 total. Despite the drop in lightering demand, 
OSG officials said they have maintained three ships in their 
lightering fleet to keep service levels consistent for their customers. 

As discussed earlier, the Corps' Institute for Water Resources 
estimated the vessel operating costs, including factors such as hourly 
fuel consumption costs, for each of the three vessels in the 
lightering fleet at the time of the reanalysis--avoiding these costs 
through reduced lightering provided the basis for lightering resource 
cost savings in a deepened channel. However, according to OSG 
officials, two of the three ships in the firm's current Delaware River 
lightering fleet are different from those the Corps modeled in its 
reanalysis, which suggests that fleet operating costs and other 
characteristics, such as pumping efficiency, may now be different. 
[Footnote 24] In 2010 the composition of OSG's lightering fleet is 
expected to change even more from the composition of the fleet used in 
the Corps' model, which could further influence the Corps' estimate of 
crude oil benefits. Fleet composition would change because of a 10-
year contract with Sunoco--OSG's largest Delaware River customer--that 
led OSG to order two new tug-barges slated for delivery in 2010. An 
OSG official explained that these vessels were specially designed to 
take into account customer requirements, desired cargo volumes, 
increased operational efficiencies, and anticipated future 
environmental requirements. By adding these vessels to its fleet, OSG 
expects that greater lightering volumes will be realized. OSG 
officials said that by fall 2010, they expect to have the two new tug-
barges operating as part of the firm's fleet, along with a third 
vessel that was not modeled in the Corps' reanalysis. OSG officials 
expect the new lightering fleet to have lower operating costs than the 
fleet that was modeled by the Corps, primarily because they will burn 
a less expensive fuel, coupled with increased operational efficiency. 
This would tend to reduce lightering resource costs and thus reduce 
the Corps' estimated crude oil benefits, all else the same. 

Finally, the delivery of the first new tug-barge would activate the 10-
year contract with Sunoco, which OSG officials said includes 
guaranteed minimum lightering volumes. If this contract causes 
lightering volumes to be higher than the Corps' model predicts for 
whatever portion of the 10 years overlaps with the deepened channel's 
50-year operation period, then lightering reduction benefits could be 
lower as a result. It is possible that increased lightering under the 
contract, if any, for Sunoco's remaining facilities could mitigate the 
drop in potential lightering cost savings resulting from the closure 
of Sunoco's Eagle Point facility. Still, without an updated analysis 
of these changes, their net effect on the Corps' estimate of crude oil 
benefits remains unclear. 

Potential Effect of Crude Oil Changes: 

The Corps has acknowledged that changes since the reanalysis could 
affect its crude oil benefit model but has not analyzed this potential 
effect. In the reanalysis's 2002 sensitivity analysis, the Corps 
showed that benefits related to crude oil could drop significantly in 
a negative-growth scenario where, for example, refineries go out of 
business (though, as we mentioned earlier, this analysis was not 
revised in the 2004 supplement despite substantive changes in the 
crude oil analysis). Further, according to the Corps, future import 
growth is responsible for about 9 percent of annual crude oil 
benefits. The Corps' primary economic consultant for the reanalysis 
agreed that a decline in crude oil imports into the Delaware River 
would reduce crude oil benefits, although he noted that the percentage 
decline for benefits would be less than the decline for imports--that 
is, it would not be a one-for-one decline. The consultant also said 
that changes to vessel operating costs in the lightering firm's fleet 
could have a significant effect on the crude oil benefit model. 

Containerized Cargo: 

The reanalysis's containerized cargo benefit assumptions may not fully 
reflect current conditions and cannot be adequately assessed without 
additional information. In the reanalysis's 2004 supplement, the Corps 
revised its containerized cargo analysis to focus on specific growth 
assumptions for the two trade routes in its analysis--one from the 
East Coast of South America and a second from Australia/New Zealand 
passing through the Panama Canal. At the time of the Corps' 
reanalysis, the two routes were served by a primary shipping firm and 
several partners operating one weekly service on each route that 
called at Philadelphia. The reanalysis's containerized cargo benefits 
depended entirely on changes in shipping practices prompted by a 45-
foot ship channel. Specifically, the reanalysis derived transportation 
cost savings from avoiding inefficient and costly trucking from the 
port of New York/New Jersey to Philadelphia--whether already occurring 
(on the South America service) or assumed to begin at some future time 
(on the Australia/New Zealand service). This trucking was an 
adaptation resulting from constraints on cargo capacity because of the 
need to maintain ship drafts that did not exceed the Delaware River's 
40-foot depth, which meant that some ships and cargo destined for 
Philadelphia would offload first at the relatively deeper port of New 
York/New Jersey. 

We were unable to verify the Corps' key assumptions underlying the 
reanalysis's expected containerized cargo benefits. Specifically, we 
could not confirm whether trucking is occurring at all, is occurring 
at a stable rate, or is growing on the South America service, and 
whether trucking has begun as a result of growth on the Australia/New 
Zealand service. According to the logistics provider for the firm that 
operates the Packer Avenue Marine Terminal, the South America weekly 
service still exists, is still operated by the same primary shipping 
firm, and still includes time-sensitive refrigerated cargo that could 
be trucked from New York/New Jersey to hasten its arrival in 
Philadelphia, thus preserving its retail value. The logistics 
provider's weekly delivery data from January through November 2009 
indicate overall growth on this service. However, we cannot fully 
assess the reanalysis's benefit assumptions for this trade route 
without information about the number of containers still being 
offloaded in the port of New York/New Jersey and trucked to 
Philadelphia, which is the basis for containerized cargo benefits. 

We also asked the logistics provider for information about the weekly 
Australia/New Zealand service, which represents 85 percent of 
containerized cargo benefits in the Corps' reanalysis. The provider 
said the weekly shipping service on that trade route is now handled in 
part by a firm that acquired the former primary shipper. In addition, 
a competing biweekly service that carries refrigerated cargo from the 
same countries began in early 2006. The logistics provider's weekly 
delivery data from January through November 2009 indicate that the 
reanalysis may have understated the number of containers that could be 
shipped directly into Philadelphia on the weekly service without being 
rerouted to New York/New Jersey with subsequent trucking back to 
Philadelphia. It is also possible that additional imports that 
otherwise would have arrived on the weekly service are instead being 
accommodated at current channel depth, without trucking, by the 
competing biweekly service that did not exist at the time of the 
reanalysis. Being able to avoid trucking only through a deeper channel 
was the basis for containerized cargo benefits in the reanalysis, and 
was a key source of uncertainty identified by the reanalysis's 
independent review panel. Ultimately, as in the case of the South 
America trade route, we cannot fully assess the reanalysis's benefit 
assumptions for this trade route without additional information about 
the extent to which trucking is occurring on the weekly service, if at 
all. 

Steel Slabs: 

The reanalysis's steel slabs benefit assumptions are not consistent 
with current market conditions. The Corps assumed that (1) 
transportation cost savings would be realized by a shift toward deeper-
drafted vessels that can load more fully in a deepened channel and (2) 
these savings would grow as steel import volumes increased. From a 
2001 base, the reanalysis forecasted a 1.1 percent annual growth rate 
for steel slab imports into the Packer Avenue Marine Terminal over the 
life of the project, which the Corps estimated would result in 
approximately 1 million tons imported in 2009--the reanalysis's 
project base year--and 1.6 million tons imported in 2059. According to 
the Packer Avenue logistics provider, 1 million tons was exceeded in 
2002 (1.1 million tons) and again in 2006 (1.2 million tons). However, 
worsening economic conditions affecting construction and other steel-
intensive industries were reflected in import volumes for steel 
products in 2008 (261,000 tons) and 2009 (63,000 tons). In the 
reanalysis's 2004 supplement, the Corps notes that the domestic market 
for steel is cyclical and exhibits a certain level of expected 
volatility. Still, import volumes would need to recover to at least 1 
million tons by 2015--the revised project base year--before steel slab 
benefits could reach the Corps' forecasted levels. 

Potential Effect of Recession and Other Observations: 

For commodities such as steel slabs, the downturn in imports may be 
directly related to the recession and imports may recover as the 
economy recovers. It is possible that, over the length of the project, 
the growth rate for this benefit category may reach or exceed the 
Corps' expected growth rate. For example, the current construction 
schedule means that benefits would not begin to be realized until at 
least 2015. Certain market and industry trends that have the potential 
to reduce project benefits--especially those tied to current economic 
conditions--could change over the next 5 years and have little or no 
negative effect on the benefit estimates or could even increase them. 
On the other hand, trends that result in part from policy and 
structural changes in the economy, such as legislation requiring 
increased fuel efficiency and the adoption of alternative fuels, are 
more likely to persist. 

Despite policy changes, competition from other sources, the recent 
downturn in the crude oil market, and other changes in the industry, 
officials from Delaware River crude oil refineries continue to be 
strong supporters of the deepening project. They agree that as long as 
they are importing crude oil, they would have an incentive to maximize 
efficiency on large vessels with drafts that exceed 40 and often 45 
feet. For example, according to an official from a refinery facility 
that receives crude oil from Canada, being able to more fully load its 
supply tankers would save one out of every seven tanker deliveries to 
the facility. The Corps' benefit model correctly presumes that 
transportation cost savings could be generated from these 
efficiencies, but given the market and industry changes since the 
modeling was performed, the benefit estimates may not be reliable. 

In addition, the Corps, the Philadelphia Regional Port Authority 
(PRPA), and others contend that the project has additional benefits 
that are not included in the Corps' reanalysis. In its reanalysis, the 
Corps based its benefit estimate for the project on existing ships, 
commodities, and trade routes, with no commodity growth or new routes 
occurring as a direct result of the deepening. However, others have 
suggested that a 45-foot channel would actually increase the amount of 
trade in the Delaware River by making its ports more marketable 
globally. Moreover, a Corps Institute for Water Resources study 
expects the expansion and deepening of the Panama Canal that would 
accommodate 50-foot ship drafts by 2014 to significantly affect 
shipping routes, port development, and cargo distribution among ports. 
[Footnote 25] According to the study, one of the expansion's greatest 
impacts will be seen in the containerized cargo trade. We heard from 
industry representatives that this trade is moving toward ever-larger 
container ships in order to realize greater economies of scale, 
including many ships that draft in excess of 40 feet. Furthermore, 
according to one of the economic experts we spoke with, significant 
growth in the chilled meat market could attract trade to Philadelphia 
and its extensive refrigerated warehouse infrastructure. To the extent 
that new cargoes and trade routes appear during the project's 50-year 
operation period, the Corps' analysis may understate project benefits 
for those commodities carried on vessels large enough to benefit from 
a 45-foot channel. However, these potential benefits would need to be 
analyzed by the Corps before they could be used to support the 
project's economic justification. This analysis would also need to 
assess the potential effect of an expansion of Delaware River trade in 
relation to other East Coast ports to ensure that any Delaware River 
benefits claimed are not merely transfers from those ports. 

Corps' Recent Economic Updates Do Not Account for Changes in 
Conditions and Future Outlook That Could Affect Project Benefits: 

The Corps' 2008 and 2009 economic updates do not account for the 
market and industry changes that have occurred since the completion of 
the reanalysis or verify certain benefit categories that were expected 
to develop by 2009. The two economic updates affirmed the level of 
expected benefits for each commodity and adjusted these estimates to 
reflect the current price level and discount rate. However, neither 
update analyzed the extent to which changes in, for example, the 
market for crude oil might affect the net benefits of the project. 
Such information would be useful to establish whether the changes have 
affected the Corps' estimate of the project's economic justification. 

Corps policy requires planners to report and maintain current 
estimates of project benefits and costs for all active funded projects 
in order to provide reasonable estimates of economic justification to 
Congress, federal decision makers, and local project sponsors. This 
policy requires economic updates for ongoing projects when more than 3 
fiscal years have passed since the project's last economic analysis. 
According to Corps guidance, economic updates do not require any major 
new analysis. Instead, they are limited to reviewing and updating 
previous assumptions, as well as limited surveying, sampling, and 
other techniques to develop a reasonable estimate of project benefits. 

The Corps' 2008 economic update did not account for changed conditions 
and uncertainties related to the Corps' commodity benefit estimates. 
According to Corps officials, the April 2008 economic update was 
developed internally for budgetary purposes and for establishing 
current project costs in preparation for the Army's June 2008 project 
partnership agreement with PRPA. The update recapped the discussion of 
major benefit categories from the two documents that constitute the 
reanalysis and presented an additional few years of data on the volume 
of commodity imports. We believe that some of these updates would be 
useful to decision makers seeking to understand how the reanalysis's 
forecasts had performed to date, but others would be less relevant. 
For example, the Corps validated its assumption of growth in blast 
furnace slag imports (and thus slag benefits) by using Waterborne 
Commerce Statistics Center data through 2005 to show that slag imports 
had exceeded the reanalysis's growth forecast. However, the Corps also 
used the center's data to show that crude oil imports had remained 
stable through 2005, but did not update the true constraint on long-
term growth identified in the reanalysis--the Corps' assumption of 0.2 
percent annual growth in the area's refinery capacity. For example, 
EIA's 2006 Annual Energy Outlook forecasted a 0.4 percent long-term 
annual decline in East Coast refinery capacity, and its 2007 outlook 
forecasted no long-term change, but the Corps did not discuss either 
of these forecasts in its 2008 economic update or assess their 
potential effect on its crude oil benefit estimate.[Footnote 26] 
Neither did the Corps contact OSG to discuss the potential benefit-
estimate implications of (1) the firm's long-term contract with Sunoco 
and the new lightering vessels it ordered (both of which were reported 
publicly in 2005), or (2) OSG's 2006 acquisition of the lightering 
firm whose operations were modeled by the Corps, which could have led 
to changes in the lightering operations that serve as the basis for 
the Corps' model. 

The Corps' 2008 update also did not resolve uncertainties related to 
some other benefit categories. For example, the Corps noted the 
healthy growth rate of container volumes overall for the Packer Avenue 
Marine Terminal for 2005 and 2006 but did not update the status of the 
weekly shipping services on the two trade routes that account for all 
containerized cargo benefits. Specifically, the Corps did not confirm 
that (1) containers were still being trucked from New York/New Jersey 
to Philadelphia on the South America trade route and (2) the expected 
rate of growth was occurring on the Australia/New Zealand trade route, 
which was projected to cause trucking to begin by 2009--both of which 
are necessary to realize any containerized cargo benefits. This 
information is especially vital given that the future status of the 
Australia/New Zealand trade route was identified by the reanalysis's 
external independent review panel as the primary source of uncertainty 
in the Corps' estimate of containerized cargo benefits. Furthermore, 
the Corps' estimate of refined petroleum benefits depends in part on 
the benefiting petroleum firm's construction of a new ship berth on 
the Delaware River that was due to be completed in 2007. The 2008 
economic update did not discuss the status of this berth; according to 
a firm official, these improvements have not been made.[Footnote 27] 

Like the 2008 update, the Corps' 2009 economic update reviewed 
commodity growth rates and adjusted benefit estimates to reflect new 
price levels and a lower discount rate. In addition, the update-- 
completed by the Philadelphia district in December 2009, reviewed by 
the New England and New York districts, and approved by the North 
Atlantic division in January 2010--reduced the project's construction 
cost estimate to reflect the latest engineering surveys of the amount 
of material needing to be dredged from the river channel. However, the 
2009 update did not present any revised modeling, sensitivity 
analysis, or related adjustments to the benefit estimates to reflect 
changes to market and industry conditions and outlook for the Delaware 
River region--for example, by incorporating the lost refinery capacity 
at the Delaware City and Eagle Point facilities into its forecasts, or 
by revisiting the sensitivity analysis from the Corps' 2002 report 
that analyzed the effect of negative growth for crude oil, both of 
which could have provided additional context for decision makers. Like 
the 2008 update, the 2009 update provided no updated information about 
the current status of the weekly shipping services on the two trade 
routes that account for all containerized cargo benefits. Moreover, 
the 2009 update reprinted the same steel slab import volumes from 2005 
and 2006 that appeared in the 2008 update, which captured the 2006 
peak in steel slab imports but ignored the precipitous decline from 
2007 through 2009. In addition, the 2009 update presented 2 additional 
years of blast furnace slag import data (2006 and 2007), but did not 
discuss the 38 percent decline in slag imports from 2005 to 2007. The 
2007 import total (529,000 tons) was just more than half of the 1 
million tons that the reanalysis forecasted would occur by 2009; 
according to a U.S. Geological Survey official who studies the slag 
industry, a private trade database indicates that the 2009 import 
total was about 125,000 tons. Finally, like the 2008 update, the 2009 
update did not revisit the Corps' expectation that the benefiting 
petroleum firm's new ship berth would be in place by 2007. 

The Corps' 2009 update did reduce the project's overall benefit 
estimate by 2.6 percent to remove benefits that were expected to be 
achieved prior to the completion of all segments of the deeper 
channel. In the reanalysis, the Corps stated that its construction 
schedule would allow benefits to be achieved at downriver facilities 
where deepening had already occurred before all upriver segments had 
been deepened. However, we observed--and Corps officials agreed--that 
the Corps' revised construction schedule makes it impossible to 
achieve these benefits. 

After we shared our preliminary findings with the Corps in February 
2010, the agency asked David Miller & Associates (DMA) to prepare a 
document that would provide us with additional information about the 
current status of Delaware River commerce to consider as we finalized 
our report. The resulting memorandum, reviewed by the Philadelphia 
district, discussed current trends in Delaware River commerce and 
identified changes in operations for relevant industries since the 
reanalysis was completed in 2004. DMA's memorandum generally agreed 
with our findings regarding declines in crude oil, steel slab, and 
blast furnace slag imports. However, the memorandum concluded that 
other than short-term impacts of the recession, Delaware River import 
trends and industry changes have the potential to increase project 
benefits. According to DMA, this is because changes that would likely 
have a negative impact on project benefits, such as the reduction in 
crude oil imports, would likely be offset by increases in 
containerized cargo, refined petroleum, and steel imports. However, 
although the memorandum asserts that additional benefits and 
beneficiaries may be present, it does not include sufficient 
quantitative analysis to show how the changed conditions and outlook 
would likely affect the reanalysis's commodity benefit estimates. For 
example, DMA's memorandum acknowledges that (1) crude oil imports have 
declined in part because of competition from imports of refined 
petroleum products, such as gasoline, to East Coast ports; and (2) 
refined petroleum vessels typically do not lighter their cargo and 
therefore tend to arrive at the Delaware River with shallower drafts 
than crude oil vessels, which often engage in lightering. DMA 
suggested that a deeper channel could result in a shift to larger 
refined petroleum vessels that could make fewer trips to deliver the 
same volume of cargo. If so, DMA states that partial replacement of 
crude oil imports by refined petroleum imports may increase project 
benefits if the transportation cost savings of avoided refined 
petroleum vessel trips are greater than the cost savings associated 
with reduced crude oil lightering over the life of the project. 
Nonetheless, this partial revision of the reanalysis's assumptions 
indicates that its crude oil and refined petroleum benefit estimates 
may no longer be reliable. Changed assumptions related to these 
benefit estimates--and those related to the estimates for 
containerized cargo, steel, and slag that also were presented in DMA's 
memorandum--could affect each benefit estimate as well as the 
project's overall net benefit estimate. 

Several Key Issues That Could Affect the Project Remain Outstanding: 

We identified three key outstanding policy issues that could impact 
the construction of the Delaware River deepening project as it moves 
forward. Specifically, the Corps (1) lowered its estimate of the 
volume of dredged material, which eliminated the need for new disposal 
sites, but it continues to face resistance to its disposal plan; (2) 
was sued by Delaware and New Jersey in October and November 2009, 
respectively, which charged that the Corps lacks the environmental 
approvals needed to proceed with the project; and (3) has an ongoing 
dispute with New Jersey and several environmental groups over the 
project's National Environmental Policy Act (NEPA) process. 

Disposal Plan Remains a Point of Contention: 

In the 2009 environmental assessment, the Corps lowered its 2002 
estimate for the amount of material that would be dredged during the 
project's 5-year initial construction period by 38 percent, from 26 
million cubic yards of material dredged during initial construction to 
16 million cubic yards. The estimate was lower because improved 
hydrographic survey technology showed less need for dredging in some 
portions of the river channel, nonfederal interests had conducted 
dredging in some portions of the channel, and higher sea levels have 
naturally deepened some portions of the channel. Unlike the estimate 
of dredged material for initial construction, the estimate for 
additional annual dredging to maintain a 45-foot channel, over the 
amount of dredging that would be required to maintain the 40-foot 
channel, remained unchanged--860,000 cubic yards per year, or 43 
million cubic yards over the 50-year life of the project. The Corps' 
lower estimate of dredged material for initial construction was 
independently validated in January 2009 by an engineering firm hired 
by PRPA, which, as the project's local sponsor, is responsible for 25 
percent of the cost of dredging and other aspects of construction. We 
found the firm's approach to validating the dredged material estimate 
to be reasonable. 

The lower estimate for dredged material allowed the Corps to eliminate 
the three additional disposal sites in New Jersey that it had planned 
to add according to the reanalysis. In its 2009 environmental 
assessment, the Corps stated that it can account for all project- 
related dredged material at its existing disposal sites. The disposal 
sites are to receive the material dredged during initial construction 
as well as the material dredged during annual maintenance of the 45- 
foot channel. As we mentioned earlier, the Corps already uses the 
existing sites in Delaware and New Jersey to dispose of dredged 
material during annual maintenance cycles for the current 40-foot 
channel. By using only its existing disposal sites, the Corps expects 
to reduce project costs by forgoing land expenditures and construction 
costs related to the new sites. The Corps has accounted for these 
plans in a revised disposal cost estimate in its 2009 economic update. 

When it revised its dredged material estimate for the deepening 
project's initial construction in the 2009 environmental assessment, 
the Corps also reduced the beneficial uses of Delaware Bay dredged 
sand from three projects to two. A third beneficial use project 
included in the reanalysis would have restored wetlands at Egg Island 
Point, New Jersey. However, Corps officials told us that the agency 
decided to defer the project in part because the Corps no longer 
expects to dredge enough sand in the bay portion of the deepening 
project to supply all three sites. 

Despite reductions in the dredged material estimate and the number of 
disposal sites needed, the Corps' disposal plan remains a point of 
contention. Specifically, New Jersey is opposed to receiving any 
dredged material from the deepening project because it believes that 
the Corps has not adequately sampled and analyzed the material. 
Furthermore, New Jersey officials believe that the material could 
contain polychlorinated biphenyls (PCBs) and other toxins that could 
contaminate the state's water supply, harm marine life, and pose a 
risk to disposal site employees.[Footnote 28] The Corps disagrees with 
this assertion, maintaining that the incremental additional dredged 
material, from 40 feet to 45 feet, is similar to the material dredged 
during annual maintenance of the 40-foot channel, which is deposited 
each year at the same disposal sites in New Jersey. The Corps contends 
that based on its sediment testing, the dredged material contains no 
harmful levels of contamination and will have no impact on water 
quality. New Jersey officials question the sufficiency of this 
sediment testing, asserting that the Corps' testing is outdated and 
did not include sediment in the project's new work areas--channel 
bends, channel widenings, and the channel bottom below 40 feet--which 
are not dredged during the Corps' annual maintenance of the channel. 
[Footnote 29] 

A 2007 agreement between the governors of New Jersey and Pennsylvania 
has also added to the controversy over the placement of the project's 
dredged material. According to a letter from the governor of New 
Jersey to the Corps, the agreement specified that dredged material 
resulting from any deepening would be deposited entirely in 
Pennsylvania, not in New Jersey. Conversely, in separate letters from 
the governor of Pennsylvania to the Corps and to the governor of New 
Jersey, Pennsylvania interpreted the agreement to mean that 
Pennsylvania would be the final repository for all of the material 
unwanted by New Jersey or Delaware that could be used for beneficial 
purposes in Pennsylvania, but that the material could be initially 
deposited and drained in federal disposal sites in New Jersey and 
Delaware before being moved to Pennsylvania. Additionally, while both 
New Jersey and Pennsylvania agreed in 2007 to the formation of a 
committee to identify sites for the disposal of the material, they 
have not yet formed this committee.[Footnote 30] Although the Corps 
and PRPA were not involved in the governors' agreement, Corps 
officials told us that while they are open to an alternative disposal 
plan in general, any new disposal plan would have to be at least as 
safe as the current plan and result in no additional costs to the 
agency. Moreover, Corps officials stated that the project's benefits 
and costs would need to be reassessed to ensure economic justification 
if under an alternative disposal plan (1) the dredged material were 
first placed in New Jersey and later moved to Pennsylvania or (2) all 
the material went directly to Pennsylvania. They also noted that an 
alternative plan could result in another needed round of project 
approvals by Congress. However, Corps officials also told us that if 
Pennsylvania agreed with New Jersey to remove the dredged material 
from New Jersey sites at a later date, then the Corps would not 
consider this agreement to be part of the deepening project. Further, 
Corps officials said the later activity would have to be a "100 
percent nonfederal expense" and would not affect the overall cost of 
the project. 

States Contend That Additional Approvals Are Needed: 

The Corps and the states of Delaware and New Jersey disagree on the 
need for additional environmental approvals related to the deepening 
project, and this is currently the subject of litigation. In 1997 the 
Corps obtained letters from both states concurring that the project is 
consistent with each state's coastal resource management policies. 
Under the Coastal Zone Management Act, a federal agency must carry out 
its activities consistent to the maximum extent practicable with the 
enforceable policies of approved state management programs. In states 
with federally approved coastal zone management programs--such as 
Delaware and New Jersey--a federal agency that undertakes a project in 
the coastal zone must provide a certification to that state that the 
project is consistent with the state's program.[Footnote 31] If a 
state deems the project consistent with the state's policies, the 
state issues a consistency "concurrence." However, in 2002, New Jersey 
informed the Corps that the state was revoking its consistency 
determination, citing substantial changes in the project's economic 
analyses and unresolved environmental issues. According to New Jersey 
officials, these issues include state requests for updated sediment 
sampling and analyses, as well as surface and groundwater monitoring 
reports, as described in a memorandum of understanding that 
accompanied the state's 1997 consistency concurrence.[Footnote 32] 
Additionally, in a 2009 letter to the Corps, Delaware asked for 
additional coordination on its consistency concurrence issued in 1997, 
citing substantial project modifications over the previous 10 years. 

The Corps disagrees with the states' positions on the consistency 
concurrences. First, Corps officials told us that they have the 
necessary concurrence letter on file from New Jersey. While New Jersey 
asserted that it "revoked" this concurrence, the National Oceanic and 
Atmospheric Administration, which administers the coastal zone 
management program, advised New Jersey that a state may not revoke a 
concurrence, noting an exception where the project has not begun and 
the effects are substantially different than previously reviewed. 
[Footnote 33] Similarly, with respect to Delaware, the Corps' position 
is that the state already concurred with the Corps' consistency 
determination. In November 2009 the Corps determined that supplemental 
coordination was not required for either state's concurrence, because 
it found that the project changes were not substantial and that the 
changed circumstances were not significant. 

In addition, in 2001 the Corps applied for a subaqueous lands and 
wetlands permit from the state of Delaware. Under that state's law, 
dredging in subaqueous lands or wetlands requires a permit. In 
comments on our 2002 report, the Under Secretary of the Army stated 
that the Corps "could not, and would not, proceed to construction 
without [Delaware's] Subaqueous Lands/Wetlands Permit," a position 
that the Under Secretary noted was a provision of the project 
cooperation agreement with the project's original local sponsor 
(Delaware River Port Authority). In 2003 a hearing officer for 
Delaware's Department of Natural Resources and Environmental Control 
recommended that the department deny the permit, citing the need for 
additional information. According to the Corps, it made several 
attempts to provide additional information to Delaware in the years 
following the hearing officer's recommendation. However, a senior 
Delaware official told us that this information could have been 
accepted only as part of a new application because the record on which 
the department's decision would be based had been closed. 

When the Army entered into a new project partnership agreement with 
PRPA in 2008, it reserved the right to determine whether the Delaware 
state permit was required as a matter of federal law, and presumably 
to move forward with the project if it determined the permit not to be 
required. In July 2009 Delaware's Department of Natural Resources and 
Environmental Control denied the Corps' request for the permit--
finding that the Corps failed in its 2001 application to demonstrate 
that adverse environmental effects resulting from the project had been 
minimized, and that the record was outdated given the significant 
changes to the project as well as additional information developed 
since 2001. Subsequently, the Corps has argued that, under a provision 
of the Clean Water Act, the agency can assert federal supremacy and 
avoid compliance with the relevant state law because the Assistant 
Secretary of the Army for Civil Works found that regulation under such 
law impaired the Corps' authority to maintain navigation.[Footnote 34] 

In summer 2009 the Corps solicited construction bids for dredging the 
first segment of the project.[Footnote 35] In response to the Corps' 
statements and actions, in fall 2009, Delaware, New Jersey, and 
several environmental groups filed separate lawsuits against the Corps 
in U.S. district courts in Delaware and New Jersey. Among other 
things, the states and environmental groups are seeking a halt to the 
project until the Corps complies with all legal requirements, 
including obtaining relevant concurrences and permits.[Footnote 36] 
However, a U.S. district court recently allowed the Corps to proceed 
with deepening of the first river segment, denying in part Delaware's 
motion for preliminary injunction. The judge also granted Delaware's 
motion in part, ruling that the Corps cannot proceed with the rest of 
the project pending resolution of the lawsuit or further order of the 
court. The judge stated her opinion that, notwithstanding the ruling, 
the project "should be completed, consistent with congressional 
intent." In reaching the decision, the court did not make a final 
ruling on Delaware's claims, but concluded that the state was unlikely 
to prevail on a majority of its claims, while finding the Corps' 
record lacking with respect to one claim.[Footnote 37] According to 
the court, its decision "gives the parties the opportunity to satisfy 
their respective obligations to govern responsibly." The environmental 
groups who intervened in the case have appealed the ruling. On 
February 23, 2010, the Corps announced it had awarded a contract to 
deepen the first segment of the project, and on March 1 this work 
began. In the meantime, the district court case, as well as the 
pending New Jersey and environmental groups' cases, is proceeding. 

Outstanding Disputes over the Project's NEPA Process: 

The Corps' 2009 environmental assessment for the Delaware River 
deepening project was controversial and has been challenged in court 
on several grounds. Specifically, New Jersey officials and several 
environmental groups have separately claimed that the assessment is 
not the appropriate mechanism for updating the last major 
environmental analysis of the project--the 1997 Supplemental 
Environmental Impact Statement (SEIS)--because, in their view, 
applicable regulations require the Corps to prepare another SEIS to 
account for project and environmental conditions that they contend 
have changed significantly since 1997. Generally, an environmental 
assessment involves a less detailed analytical process than other NEPA 
documents, such as an Environmental Impact Statement (EIS) or SEIS. 
Instead, it is intended to be a concise document that provides 
sufficient evidence and analysis for determining whether to prepare an 
EIS or SEIS. In commenting on a draft of this report, the Department 
of Defense noted that it has followed the regulations concerning the 
NEPA documents. Specifically, the stated purpose of the environmental 
assessment included to evaluate the impacts of changes to the 
deepening project, as well as changes to the existing conditions in 
the project area from those described in the 1992 EIS and 1997 SEIS. 
On this basis, the Corps concluded that none of the changes to the 
proposed project were substantial and there were no new circumstances 
or information that can be considered significant, and therefore 
determined that an SEIS was not required. 

According to New Jersey and the environmental groups, the 
environmental assessment overlooked certain elements of the project, 
relied on outdated information, and did not sufficiently explore all 
of the potential adverse impacts from the project. For example, they 
believe additional and updated sediment sampling and analyses are 
needed to fully characterize the materials to be dredged in the 
deepening project. As a result of these concerns, New Jersey and the 
environmental groups are now asking a U.S. district court, as part of 
the lawsuits they filed in fall 2009, to order the Corps to issue a 
new SEIS before proceeding with the project. 

In this regard, the Corps' process for public comments on the 
deepening project has also been criticized. On December 17, 2008, the 
Philadelphia district, via a public notice, solicited comments from 
stakeholders concerning environmental changes as well as project 
changes since the 1997 SEIS, such as changes to the amount of 
estimated dredged material and the elimination of new disposal sites. 
The Corps' notice indicated that all comments should be made by 
December 31, 2008. Among other things, environmental groups criticized 
the Corps for not giving stakeholders sufficient time for commenting 
on these changes and for scheduling the comment period over a major 
holiday period. Following these criticisms, the Corps extended the 
public comment period by 2 weeks. 

The public notice also did not explicitly inform the public that their 
comments would be used to prepare an environmental assessment. 
Instead, the notice asked the public for comments related to a summary 
of project changes and to identify any applicable existing and new 
information generated subsequent to the 1997 SEIS, to be used to 
update the environmental record and to determine whether further 
environmental work and analyses would be needed. Owing to both the 
abbreviated response period and the confusion over the public notice's 
purpose, the environmental groups we spoke to stated that some 
potential respondents may not have commented, and comments the Corps 
did receive may not have been comprehensive. 

The environmental groups also contend that the Corps should have 
circulated a draft of the environmental assessment for public comment. 
There was professional disagreement between the Corps and the Army 
concerning whether a comment period for the draft environmental 
assessment was necessary. Specifically, in March 2009 the Corps' 
Director of Civil Works asked permission from the Assistant Secretary 
of the Army for Civil Works to circulate the draft environmental 
assessment for public comment before it was issued in final form. In 
his request, the director identified several reasons why circulation 
of the draft assessment was advisable. The Assistant Secretary of the 
Army, however, denied his request, disagreeing with the rationale and 
focusing on its finding that circulation was not legally required-- 
maintaining that the initial notice and comment period constituted a 
sufficient amount of public participation and that there was no legal 
requirement for additional public involvement.[Footnote 38] While 
Corps officials in the Philadelphia district told us that Corps 
guidance does not direct the agency to provide a public comment period 
for draft environmental assessments, they could not identify other 
environmental assessments that the district had issued without first 
circulating the draft for public comment. The reason that NEPA 
regulations emphasize public involvement through mechanisms such as 
public comment is that the law's purpose, in part, is "to require 
disclosure of relevant environmental considerations that were given a 
'hard look' by the agency, and thereby to permit informed public 
comment on [the agency's] proposed action and any choices or 
alternatives that might be pursued with less environmental harm." 
[Footnote 39] 

Conclusions: 

The Corps has had the difficult task of developing benefit and cost 
estimates for the Delaware River deepening project that are based on 
what may occur over a 50-year period of analysis--a period that begins 
only after 5 years of channel dredging have been completed. For such a 
project, economic uncertainties associated with making projections 
about future conditions are important to consider because expectations 
about future market conditions and benefits often may not be realized. 
As the Corps' policies recognize, analyzing uncertainties can help 
decision makers judge whether a project would be warranted under a 
range of economic conditions. The Corps' reanalysis has provided a 
more solid foundation for estimating the project's benefits and costs 
and has used sensitivity analysis to analyze the uncertainties 
associated with several key assumptions. 

However, since the reanalysis was completed, market and industry 
conditions have changed significantly in ways that raise questions 
about the Corps' project benefit estimates going forward. While some 
of these changes could be short-term trends, others could have longer- 
lasting impacts. Such changes create additional uncertainties about 
the deepening project. In some cases, such as blast furnace slag, the 
changes affect a small portion of the project's estimated benefits, 
but in other cases, such as crude oil, containerized cargo, and steel 
slabs, the changes are associated with commodities that make up most 
of the project's estimated benefits. A key purpose of the Corps' 
periodic economic updates is to analyze these uncertainties by 
collecting enough additional information to ensure that decision 
makers are presented with reasonable and timely estimates and that the 
project is warranted under a range of economic conditions. Because the 
Corps' economic updates have not accounted for the potentially 
significant impact that some market and industry trends could have on 
the project's estimated benefits, federal decision makers do not have 
the most current information about the project, including whether 
adjustments to the assumptions in the Corps' benefit models are 
necessary. Such information would help decision makers more fully 
assess the project's economic justification. 

Noneconomic aspects of project implementation can also add to 
uncertainties about the project. A key area of such uncertainty is the 
outcome of the legal challenges to the project's environmental 
approvals and compliance. In particular, the Corps has made several 
decisions--such as soliciting information from the public over the 
winter holiday, and then, following Army direction, not seeking public 
comment on the draft environmental assessment--that have exacerbated 
public concerns over environmental issues, and as a result, its 
communications with the public regarding its actions have not been as 
open as might have been advisable for such a controversial project. 

Recommendations for Executive Action: 

To better ensure that decision makers have the most current 
information about changes that could affect the benefits of the 
Delaware River deepening project, we recommend that the Secretary of 
Defense direct the Chief of Engineers and Commanding General of the 
U.S. Army Corps of Engineers to provide an updated assessment to the 
Assistant Secretary of the Army for Civil Works, and to Congress, of 
relevant market and industry trends and outlook that specifies the 
extent to which the data and assumptions underlying each benefit 
category have changed, and the effect of any changes on each benefit 
estimate and the project's net benefit estimate. This assessment 
should be issued as a public document and become part of the project's 
official record. 

To improve consistency and transparency in how the Corps handles 
public participation in the development of environmental documents 
that are related to controversial projects and that the Corps believes 
have no applicable NEPA requirement, we recommend that the Chief of 
Engineers develop guidance on the appropriate timing and approaches 
for public notice and comment on such documents. 

Agency Comments and Our Evaluation: 

We provided a draft of this report to the Department of Defense for 
review and comment. The department generally agreed with the 
recommendations in our report. Specifically, the department concurred 
with our recommendation that the Corps provide an updated assessment 
of relevant market and industry trends and outlook that specifies the 
extent to which data and assumptions underlying each benefit category 
have changed and the effect of these changes on project benefit 
estimates. The department agreed to have the Corps prepare an updated 
quantitative assessment that would incorporate the long-term trend in 
the economy over the project's 50-year planning period. In addition, 
the department partially concurred with our recommendation that the 
Corps develop guidance on the appropriate timing and approaches for 
public notice and comment on environmental documents that are related 
to controversial projects and that the Corps believes have no 
applicable National Environmental Policy Act requirement. The 
department agreed that the Army will review and evaluate the need for 
clarifying guidance regarding whether or when a draft Corps Civil 
Works environmental assessment (EA) and finding of no significant 
impact (FONSI) should be circulated for public comment before they are 
finalized.[Footnote 40] The department notes that it has no reason to 
believe that its existing regulations and guidance regarding this 
subject are defective or in need of modification. While there are 
regulations addressing the typical scenario where an environmental 
assessment is the first NEPA document developed (e.g., there is no EIS 
previously prepared), we believe that no Corps guidance exists for the 
less common scenario where a relatively old EIS or supplemental EIS 
already exists for a project that has not yet been constructed, as was 
the situation in 2009 when the Corps prepared its EA for the deepening 
project. The department acknowledges that it would be beneficial to 
issue clarifying guidance for conducting an EA in such a scenario. 

The department's official comments are presented in appendix III. We 
also received technical comments from the department, which we have 
incorporated as appropriate throughout the report. In addition, we 
invited Delaware, New Jersey, and Pennsylvania to comment on draft 
report excerpts discussing issues relevant to each state. We received 
comment letters from New Jersey and Pennsylvania, which we present in 
appendixes IV and V, respectively. We also received technical comments 
from all three states, which we incorporated as appropriate throughout 
the report. 

As agreed with your office, unless you publicly announce the contents 
of this report earlier, we plan no further distribution until 30 days 
from the report date. At that time, we will send copies of this report 
to the appropriate congressional committees, the Secretary of Defense, 
the Chief of Engineers and Commanding General of the U.S. Army Corps 
of Engineers, and other interested parties. In addition, this report 
will be available at no charge on the GAO Web site at [hyperlink, 
http://www.gao.gov].

Appendix I: Objectives, Scope, and Methodology: 

Our objectives were to determine (1) the extent to which the U.S. Army 
Corps of Engineers' (Corps) reanalysis addressed the economic analysis 
limitations we identified in 2002; (2) the extent to which the benefit 
projections the Corps included in its reanalysis of the project, as 
updated, are consistent with current and anticipated future market and 
industry conditions; and (3) what other key issues, if any, could 
affect the project, and the extent to which the Corps has accounted 
for these issues and their potential impacts. 

To determine the extent to which the Corps' reanalysis addressed the 
economic analysis limitations we identified in 2002, we reviewed our 
2002 report[Footnote 41] to identify the key limitations we had found 
in the Corps' 1998 analysis. These limitations ranged from errors in 
benefit and cost estimation--such as the misapplication of commodity 
growth rates and the omission of disposal site construction costs for 
future channel maintenance dredging--to concerns about the Corps' 
treatment of economic uncertainty and the lack of internal quality 
control in the Corps' report review process. We then reviewed the 
Corps' reanalysis--the 2002 Comprehensive Economic Reanalysis Report 
and the 2004 Supplement to Comprehensive Economic Reanalysis Report-- 
and supporting documents, and assessed the extent to which the 
reanalysis generally addressed the limitations we had identified 
earlier consistent with standard economic principles for conducting a 
benefit-cost analysis. The supporting documents we reviewed included 
detailed quantitative analyses for each of the five benefiting 
commodities included in the reanalysis--crude oil, containerized 
cargo, steel slabs, blast furnace slag, and refined petroleum--as well 
as the Corps' calculation of benefits for reuse of dredged sand at 
Broadkill Beach. We also reviewed documents that provided greater 
context for the Corps' reanalysis, such as the agency's official 
comments in response to the findings and recommendations in our 2002 
report, and two subsequent internal documents that updated and further 
explained the reanalysis's benefit and cost assumptions--the Corps' 
2008 and 2009 economic updates. We interviewed Corps officials at the 
Philadelphia district with primary responsibility for the reanalysis's 
benefit-cost analysis to gain further understanding of the steps taken 
by the Corps to address the limitations. We also discussed the 
reanalysis with officials from the Corps' North Atlantic division and 
its headquarters in Washington, D.C. For further information about the 
reanalysis, we interviewed the primary economic consultant for the 
reanalysis from David Miller & Associates (DMA), the firm that the 
Corps hired to prepare key parts of the reanalysis, including an 
updated analysis of project benefits and associated costs. Finally, we 
presented our findings related to each limitation in a table for the 
Corps to review, at which time we requested additional information and 
documentation for certain items, as appropriate. In addition, we 
discussed the Corps' analyses with an academic expert who has analyzed 
the lightering and crude oil industries in the Delaware River. 

To determine the extent to which the benefit projections the Corps 
included in its reanalysis of the project, as updated, are consistent 
with current and anticipated future market and industry conditions, we 
attempted to verify key data and assumptions underlying the key 
benefit categories in the reanalysis's 2002 report and 2004 
supplement, as well as the Corps' 2008 and 2009 economic updates, 
using data on the general trends since the Corps conducted its 
reanalysis, current conditions, and the expected outlook for relevant 
Delaware River imports and industries. For crude oil, we used data on 
imports to Delaware River ports collected by the Department of 
Energy's Energy Information Administration (EIA). Importers of crude 
oil and petroleum products are required to report on a monthly basis 
to EIA. To assess the reliability of these data, we reviewed existing 
agency information about the data and the agency's data quality 
procedures, and we interviewed agency officials knowledgeable about 
the data. We used information from the Department of Commerce and 
industry sources to corroborate the general historical trend exhibited 
in the EIA import data. We note that EIA's import data for 2009 are 
preliminary and may be revised. We determined that the EIA data are 
sufficiently reliable for the purposes of this report. We also 
reviewed EIA's Annual Energy Outlook forecasts for U.S. crude oil 
imports and refinery capacity on the East Coast; EIA forecasts were a 
primary source for the Corps' in developing the reanalysis's crude oil 
benefit estimate. To assess the reasonableness of these forecasts, we 
reviewed supporting documentation on the approach and key assumptions 
and we interviewed knowledgeable EIA officials to discuss possible 
reasons for observed declines in historical imports and changes in the 
agency's forecast for crude oil refinery capacity and imports. We note 
that EIA may revise its forecasts over time as new information becomes 
available. 

To further assess trends and outlook in the Delaware River crude oil 
industry, we interviewed officials from the three refinery firms that 
own the six Delaware River refinery facilities included in the Corps' 
reanalysis,[Footnote 42] as well as representatives of Overseas 
Shipholding Group,[Footnote 43] which conducts the lightering 
operations for those firms, to discuss their past and present crude 
oil-related operations. We also interviewed EIA officials and an 
academic expert knowledgeable about oil markets. 

To assess current conditions and outlook for containerized cargo and 
steel slab imports, we reviewed Corps data in the reanalysis and 
subsequent economic updates and we interviewed the logistics provider 
for the Packer Avenue Marine Terminal. Although we obtained 
information on containerized cargo import trends, we were unable to 
obtain data with which to verify key assumptions that the Corps used 
to support its containerized cargo benefit estimate. Specifically, we 
could not confirm that (1) containers were still being trucked from 
the port of New York/New Jersey to Philadelphia for the weekly service 
on the South America trade route and (2) the expected rate of growth 
was occurring for the weekly service on the Australia/New Zealand 
trade route, which was supposed to cause trucking to begin by 2009--
both of which are necessary to realize any containerized cargo 
benefits. For information on blast furnace slag imports, we reviewed 
annual reports by the U.S. Geological Survey on the slag industry in 
the United States and we interviewed a U.S. Geological Survey official 
who is knowledgeable about the slag industry. We believe that the 
information is sufficiently reliable for the purposes of this report. 

For details about the operational status of the reanalysis's sole 
refined petroleum beneficiary, we interviewed a representative of 
Magellan LP, the firm that acquired the benefiting petroleum terminal 
identified in the reanalysis. For additional background on all 
commodities, we reviewed historical import data from several 
additional sources, including the Corps' Waterborne Commerce 
Statistics Center,[Footnote 44] the U.S. Department of Agriculture, 
and the U.S. Department of Commerce. 

To determine what other key issues, if any, could affect the project, 
and the extent to which the Corps has accounted for these issues and 
their potential impacts, we reviewed the limitations that we had 
identified in our 2002 report to develop a list of key noneconomic 
concerns for further examination. This included the Corps' handling of 
environmental policy issues, such as its pursuit of a subaqueous lands 
permit from Delaware for dredging in that state's waters. Similar to 
the methodology described in our first objective, we used these 
previously identified concerns as criteria for reviewing the 
reanalysis and other key documents, as well as the Corps' 2009 
environmental assessment, to determine whether and how each issue was 
addressed by the Corps. We also requested from the Corps all comment 
letters received in response to its public request for information in 
advance of its 2009 environmental assessment. These letters--from 
federal, state, and local agencies; environmental groups; and private 
citizens--detailed concerns about the project's potential impacts and 
changes in the project area since the Corps' 1997 supplemental 
environmental impact statement (SEIS). We reviewed these letters, and 
the content analysis that the Corps prepared to summarize them, in 
order to gain an understanding of prominent issues and controversies 
associated with the project. Throughout our review we also read local 
media accounts of these issues and controversies. Further, we reviewed 
correspondence and legal filings related to Delaware's, New Jersey's, 
and regional environmental groups' ongoing disputes with the Corps 
over environmental approvals for the deepening project. We discussed 
the project with several regional environmental groups, including some 
that were involved in lawsuits to stop the project. Finally, once we 
had determined key policy and legal issues affecting the project, we 
discussed these issues with the Corps and requested more information 
and documentation of the Corps' plans where necessary. We also asked 
representatives of the three states likely to be most affected by the 
project--Delaware, New Jersey, and Pennsylvania--to review our 
interpretation of these issues to the extent that it was relevant to 
each state. 

For all three objectives, we consulted experts in the fields of 
economics and lightering, environmental groups with an interest in the 
project, representatives of firms likely to be affected both 
positively and negatively by the project, and the Philadelphia 
Regional Port Authority (PRPA), the project's local sponsor. Where we 
obtained other analyses or external studies, we considered the 
contents of these studies but conducted our own independent review. 
For example, the Corps' reduced estimate of dredged material from 
initial construction was independently validated in January 2009 by an 
engineering firm hired by PRPA, which, as the project's local sponsor, 
is responsible for 25 percent of the cost of dredging and other 
aspects of construction. We reviewed the firm's approach to validating 
the revised dredged material estimate and found it to be reasonable. 

We conducted this performance audit from March 2009 through March 2010 
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. 

[End of section] 

Appendix II: Additional Observations about the Project's Associated 
Costs: 

It has now been more than 7 years since the Corps has asked the 
refineries about changes to their facilities. Since the reanalysis, 
some refinery facilities have undergone significant structural and 
operational changes that could affect the associated costs of the 
project, which are the private costs that would need to be incurred, 
in addition to project costs, to achieve the project's full benefits. 
Associated costs account for about 10 percent of the project's total 
economic first costs.[Footnote 45] Specifically: 

* Associated costs could be lower. According to one refinery, a tanker 
dock at one of its facilities was completely rebuilt in 2008 to 
address structural problems. In anticipation of a deepened channel, 
the new dock was constructed to accommodate tankers needing a depth of 
45 feet. Since this work was undertaken after the Corps' reanalysis, 
the project's associated costs could be lower than the reanalysis 
initially predicted. In 2002 the Corps estimated that these 
modifications would cost $3.6 million. In addition, the recent closure 
of Sunoco's Eagle Point facility, if permanent, could decrease 
associated costs because no modifications would need to be made at 
this facility. In 2002 the Corps estimated that it would cost $362,000 
to modify this facility. 

* Associated costs could be higher. Refinery officials expressed 
concerns about the availability of private disposal space for dredged 
material, which could be costly. According to PRPA, private dredging 
and disposal costs have risen since the time of the reanalysis due to 
higher fuel costs, among other factors. If the disposal cost for 
dredged material is significantly more now than it was in 2002, the 
project's associated costs could increase. 

Officials from all three refinery firms told us that they supported 
the deepening project. However, they also told us that they would need 
to analyze the project's benefits and costs for their firms to 
determine whether they would commit to making the improvements 
necessary to take advantage of the project. These improvements could 
be substantial: deepening their ship berths, retrofitting their docks, 
or expanding their storage capacity. As our discussions with refinery 
officials suggest, firms are not likely to commit to the modifications 
needed to realize project benefits until they have conducted their own 
financial analysis of the benefits they would gain. If the firms 
decided against making the necessary modifications, then the project's 
benefits could be lower than initially estimated. 

These decisions are particularly important in light of the Army's 
project partnership agreement with PRPA. The agreement specifies that 
PRPA is responsible for ensuring that the local facilities undertake 
the modifications necessary to take advantage of the deepening 
project. However, this agreement does not require PRPA to produce 
third-party agreements with these potential beneficiaries as evidence 
of their commitment before project construction could proceed. In 
contrast, under the agreement with the project's original local 
sponsor (the Delaware River Port Authority), the local sponsor had to 
provide copies of third-party agreements as evidence of local 
facilities' commitment to make the modifications necessary to realize 
project benefits. Corps officials said that in the time between the 
signed agreements with the Delaware River Port Authority and PRPA, the 
model project partnership agreement, developed by Corps headquarters, 
changed so that provisions for third-party agreements are no longer 
included. 

Nevertheless, according to Corps officials with whom we spoke, the 
agency expects benefiting firms will modify their facilities once 
project construction begins. The Corps assumes that the beneficiaries 
will make separate arrangements with the Corps' dredging contractor 
while the contractor is working in each beneficiary's section of the 
river. By using the Corps' contractor, the beneficiaries could save 
certain dredging costs, such as those related to the transfer of 
equipment to and from the site and the installation and removal of

Director, Natural Resources and Environment: 
U.S. Government Accountability Office (GAO): 
441 G Street, N.W. 
Washington, DC 20548: 

Dear Ms. Mittal: 

This is the Department of Defense response to the GAO draft report, 
GAO-10420, "Delaware River Deepening Project: Comprehensive Reanalysis 
Corrected Errors, but Several Issues Still Need to Be Addressed," 
dated March 2010 (GAO Code 36150). Thank you for the opportunity to 
comment on the draft report. 

We concur with your first recommendation. The Corps will perform an 
updated quantitative assessment of the impact of relevant market and 
industry trends on the previously projected project benefits. The 
updated assessment will augment the qualitative port assessment 
previously provided by the Corps for consideration during the 
development of the GAO draft report. 

We partially concur with your second recommendation that the Chief of 
Engineers develop guidance on the appropriate timing and approaches 
for public notice and comment on environmental documents that are 
related to controversial projects that the Corps believes to have no 
applicable National Environmental Policy Act requirement. We do not 
believe that our existing regulations, which are based on the Council 
on Environmental Quality regulations that are applicable to all Federal
agencies, are either defective or in need of modification. However, we 
acknowledge that it would be beneficial to issue clarifying guidance 
for conducting the analysis contemplated by 40 C.F.R. § 1502.9(c), 
where a relatively old Environmental Impact Statement or Supplemental 
Environmental Impact Statement exists for a project that has not yet 
been constructed, as the situation was in the present case. 

Responses to the GAO recommendations are enclosed. 

Very truly yours, 

Signed by: 

Jo-Ellen Darcy:

GAO Draft Report — Dated March 15, 2010: 
GAO 10-420 (GAO Code 36150): 

Delaware River Deepening Project: Comprehensive Reanalysis Corrected
Errors, but Several Issues Still Need To Be Addressed: 

Department Of Defense Comments To The Recommendations: 

Recommendation 1: To better ensure that decision makers have the most 
current information about changes that could affect the benefits of 
the Delaware River deepening project, we recommend that the Secretary 
of Defense direct the Commanding General and the Chief of Engineers of 
the U.S. Army Corps of Engineers to provide an updated assessment to 
the Assistant Secretary of the Army for Civil Works and to Congress of 
relevant market and industry trends and outlook that specifies the 
extent to which the data and assumptions underlying each benefit 
category have changed and the effect of any changes on each benefit 
estimate and the project's net benefit estimate. This assessment 
should be issued as a public document and become part of the project's 
official record. 

DOD Response: Concur. The Corps will perform an updated quantitative 
assessment of the impact on project benefits resulting from relevant 
market and industry trends and outlook. This work effort will augment 
the qualitative port assessment previously provided by the Corps to 
the GAO for consideration during the development of the agency's Draft 
Report, and will incorporate the long-term secular trend in the 
economy over the 50-year planning period of analysis. It should be 
noted that short-term business cycle fluctuations, such as the deep 
2009 recession, are a consideration, but should not be the determining 
basis for defining a project's benefits. 

Recommendation 2: To improve consistency and transparency in how the 
Corps handles public participation in the development of environmental 
documents that are related to controversial projects and that the 
Corps believes have no applicable NEPA requirement, we recommend the 
at the Chief of Engineers develop guidance on the appropriate timing 
and approaches for public notice and comment on such documents. 

DOD Response: Partially Concur. The Department of the Army (DA) will 
review and evaluate our existing guidance regarding whether or when a 
draft Corps Civil Works EA/FONSI should be circulated for public 
comment before it is finalized. 

Presently we have no reason to believe that our existing regulations 
and guidance regarding this subject are defective or in need of 
modification. 

There are only three circumstances in which the Corps is required to 
circulate a draft EA/FONSI for public comment, none of which encompass 
the present situation. The first two circumstances are mandated by 
CEQ's legally binding NEPA regulations at 40 C.F.R. § 1501.4(e) (2): 

1. where the proposed action is, or is closely similar to, one of a 
class of actions designated as normally requiring an EIS under that 
agency's NEPA regulations; or; 

2. where the nature of the proposed action is one without precedent.
The Corps' Civil Works NEPA regulation, 33 C.F.R. § 230.1, articulates 
the third circumstance in which the Corps is required to circulate a 
draft EA/FONSI: 

"In the case of feasibility, continuing authority, or special planning 
reports and certain planning/engineering reports, the draft FONSI and 
EA should be included within the draft report and circulated for a 
minimum 30 days review to concerned agencies, organizations and the 
interested public (40 C.F.R. § 1501.4(e)(2))." 

In all other circumstances, the decision to circulate a Corps Civil 
Works draft EA/FONSI before finalization is discretionary. The draft 
EA/FONSI may be circulated for public comment if the Army or Corps 
decision-maker determines that it would be advantageous or appropriate 
to do so. 

In the case of the Delaware River Deepening Project's most recent EA, 
then-ASA(CW) Woodley determined that it was not necessary or 
appropriate to circulate that particular draft EA before it was 
finalized. We believe that decision was proper under the circumstances 
involved. The circumstances presented the issue whether the EA 
documenting that analysis contemplated by 40 C.F.R. § 1502.9(c), 
required additional public comment and participation where an 
environmental record exists in the form of a relatively old EIS or 
SEIS project, and the project has not yet been constructed. The Corps 
will undertake an additional review and consider whether internal 
guidance, in addition to 40 C.F.R. § 1502.9(c), would be useful to 
address these situations.

Mr. David A. Brown: 
United States Government Accountability Office: 
441 G Street, NW: 
Washington, DC 20548: 

Dear Mr. Brown:	 

Thank you and your staff for speaking to me and Suzanne Diettick on 
March 4th about the Delaware River Deepening Project (Project) 
currently being undertaken by the Army Corps of Engineers, 
Philadelphia District (ACOE). We certainly appreciate that the 
Government Accountability Office (GAO) is reviewing the economic and 
environmental issues surrounding the Project, and will be issuing a 
new report on or around March 25, 2010. 

As we discussed, the New Jersey Department of Environmental Protection 
(NJDEP) has serious concerns about this Project, and wants to ensure 
that New Jersey's air and water are not harmed should the Project 
continue to go forward. I am enclosing a mark-up of the draft report 
that we discussed, with NIDEP's comments incorporated, with the hope 
that the GAO will seriously consider the points that we raised. Please 
note that we have a correction on our mark up regarding the number of 
tons of NOx/year that are being offset in the New York Harbor 
Deepening Project. 

NJDEP is particularly concerned that the ACOE will be deepening the 
Delaware River, and depositing the dredged materials in upland 
confined disposal facilities (CDFs) located primarily in New Jersey. 
Our concern is that large segments of the Delaware River that will be 
dredged have not been comprehensively sampled for at least seventeen 
years. In NIDEP's view, a significant amount of this dredged material 
will come from industrial parts of the River (between 
Philadelphia/Camden to the Port of Wilmington), where contamination 
with polychlorinated biphenyls (PCBs), polyaromatic hydrocarbons (PAI-
Is), and other highly toxic substances is likely to be high and in 
violation.of NJDEP's regulatory standards. A massive oil spill 
occurred in this part of the River in 2004. NJDEP expects that runoff 
from the dredged material stored in the CDFs will impact the surface 
waters of the Delaware River and will also seep into and contaminate 
the groundwater. If the ACOE knows the levels of contamination in the 
dredged materials, then controls can be put in place to manage the 
contaminated material properly, and prevent further water pollution. 
For these reasons, NJDEP has been insisting on updated, comprehensive 
sampling of the new work areas of the River. 

NJDEP realizes that the sediment sampling it is demanding will add to 
the overall cost of the Project. In the New York Harbor Deepening 
Project, however, the New York District of ACOE performed 
comprehensive, state-of-the-art sediment sampling prior to the 
initiation of construction activities for each contract. We were able 
to use our experience with the New York Harbor Deepening Project to 
estimate the costs of performing sediment sampling in the Delaware 
River. We believe that the additional sampling will range from $4.8 to 
$5,4 million (or less than 2% of the total project costs). if the 
sediment sampling produces results that exceed New Jersey's regulatory 
standards such that the dredged materials could not be managed at the 
CDFs, then additional management of the materials will be required, 
which could add approximately $400,000,000 to the total project costs. 
This figure is based on the projected volumes to be removed from areas 
of the Delaware River where we expect there to be the most 
contamination (e.g., between Philadelphia/Camden to the Port of 
Wilmington). 

In addition, NJDEP has serious concerns that the ACOE is choosing to 
mitigate the air emissions caused by the construction of the Project 
(e.g., diesel emissions caused by the dredgers, tug boats, trucks and 
other heavy equipment) exclusively through the purchase of Emission 
Reduction Credits (ERCs). The ACOE is proposing to spend $3.3 million 
to offset 607 tons/year of NOx emissions. In contrast, the New York 
District spent approximately $20 million on new mitigation projects 
(e.g., engine upgrades and air pollution controls on the Staten Island 
Ferries, repowering tugboats, and ERCs) to offset the 1,265 tons/year 
of NOx emission increases caused by the deepening of New York Harbor. 
NJDEP believes that if the Philadelphia District approached air 
conformity in the same manner as the New York District, it would be 
spending much more on new mitigation projects that actually improved 
air quality. 

Again, we appreciate the opportunity to review the draft report and to 
provide you with our comments. If you need any additional information, 
please feel free to contact us. 

Sincerely, 

Signed by: 

Bob Martin:

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

Subject: Delaware River Main Channel Deepening Project: 

Dear Ms. Mittal: 

In my capacity as Chairman of the Philadelphia Regional Port Authority 
("PRPA") -- an independent agency of the Commonwealth of Pennsylvania 
and the local sponsor for the Delaware River Main Channel Deepening 
Project (the "Project") -- I am writing to provide our views, 
generally, on the Project as well as clarification on the 
understanding between Governor Rendell and Governor Corzine regarding 
the disposal of dredged materials. 

The Army Corps of Engineers ("ACOE") has been planning the Project in 
earnest since 1992 and, in accordance with applicable law, has 
followed a planning and implementation process that has been thorough, 
inclusive and protective of both public interest and the environment. 
The ACOE has been responsive to reasonable and justified concerns 
during the planning/implementation process and has worked diligently 
to resolve outstanding issues to the greatest extent possible. As a 
result of these efforts, the ACOE and PRPA executed a Project 
Partnership Agreement ("PPA") on June 23, 2008, federal and non-
federal funds have been appropriated, and construction in Reach C of 
the Project began in February 2010. 

Certain interest groups have opposed the Project on environmental 
grounds and certain state regulatory agencies from Delaware and New 
Jersey have expressed concerns in regard to the process that the ACOE 
followed in order for the Project to proceed. As noted above, the 
process followed was in accordance with applicable law and, since 
1992, the environmental impacts of the Project have been studied 
leading to the preparation of numerous reports that incorporated input 
from regulatory agencies and the public. Furthermore, the ACOE and 
PRPA repeatedly met with stakeholders in the Project to address their 
concerns. 

The concerns of the interest groups and state regulatory agencies have 
also been formally raised in court proceedings. To date, the United 
States District Court for the District of Delaware and the United 
Stated Third Circuit Court of Appeals have ruled in favor of the ACOE, 
validating the process followed by the ACOE and allowing the Project 
to proceed. I encourage you to carefully scrutinize for accuracy any 
issues that opponents of the Project contend are "unresolved" in light 
of these court rulings. There may be parties who continue to be 
dissatisfied with aspects of the Project, but there are no unresolved 
issues. 

Regarding the understanding between Governor Rendell of the 
Commonwealth of Pennsylvania and former Governor Corzine of the State 
of New Jersey regarding the disposal of dredged materials, I would 
like to point out the following: 

1. The understanding is a non-binding agreement between Pennsylvania 
and New Jersey and is independent of the Project. As directed by 
Congress, ACOE is constructing the federally authorized project, 
including the use of the existing federal disposal sites as specified 
in the signed PPA and all of the accompanying economic and 
environmental reviews. 

2. In order to use the dredged material beneficially, the following 
process -- the same process the ACOE currently uses for the beneficial 
use of maintenance material -- needs to be undertaken: 

* The placed material needs to be de-watered. 

* Specific uses for beneficial uses need to be identified. 

* Appropriate environmental clearances need to be obtained. 

* Removal needs to be funded by the beneficiary. 

3. The identified disposal placement sites will be used for storage and
dewatering of the dredged material until the respective states 
complete the process to use the material beneficially. Since the 
placement sites are federally owned and will be available for the life 
of the Project, the stored material will be available for beneficial 
use following the de-watering process. 

4. Governor Rendell repeatedly assured the then Governor of New Jersey
and the former and current Governors of Delaware that the Commonwealth 
of Pennsylvania will accept for beneficial re-use the dredged material 
from the Project that neither New Jersey nor Delaware desire. Until 
the final beneficial use of dredged material is defined and 
implemented, the dredged material will remain deposited in the 
federally owned disposal sites in New Jersey, Delaware and 
Pennsylvania. 

During the current review of the Project's benefits, you contacted the 
PRPA to obtain information on the Port's current and anticipated 
commerce levels at various facilities. I would like to point out that 
during the current recession the volume and mix of cargoes coming to 
the Pod have changed since the start of the recession. This is true of 
every major port complex in the United States. For example, in the 
last year the Port of New York/New Jersey experienced a decline in 
containers of almost 20%. 

Certainly the economic analysis for any ACOE authorized deep draft 
commercial navigation project could be considered to have unresolved 
issues regarding the nature and extent of benefits previously 
estimated. However, the underlying strength of the regional economy 
has not changed and we fully expect the Port to recover and grow. 
Indeed, the economic outlook for Delaware River port facilities 
changes on a daily basis as demonstrated by the recent agreement
of two shipping lines to call on PRPA facilities and bring an 
additional 76 ships per year to Philadelphia. The impending completion 
of improvements to the Panama Canal will only further enhance the Port 
and the region's economic strength. 

Thank you for your attention and consideration with respect to these 
matters. 

Respectfully, 

Signed by: 

John H. Estey:

[3] Corps benefit and cost estimates cited in this report are based on 
the Corps' planned 5-year construction period. Estimates could change 
if project construction takes longer than 5 years. 

[4] Project-related disposal at the Pennsylvania site is limited to 
rock that would be removed from the river after blasting in the 
vicinity of Marcus Hook, Pennsylvania.

[6] The Corps' 1998 LRR presented benefit and cost estimates at 1996 
price levels and federal fiscal year 1997 discount rate (7.375 
percent); the reanalysis's 2004 supplement presented benefit and cost 
estimates at 2002 price levels and federal fiscal year 2004 discount 
rate (5.625 percent). Some of the change observed in benefit and cost 
estimates between the LRR and the reanalysis was due to this change in 
price level and discount rate. 

[7] Corps guidelines state that districts should discount future 
benefits and costs that accrue in different periods back to their 
present values for valid comparison and should revise this discount 
rate periodically. The Corps also directs districts to adjust price 
levels to account for changes that occur over time in the prices of 
various factors, such as commodities and wages. 

[8] At the time of the reanalysis, Coastal Eagle Point owned one of 
the current Sunoco facilities. In addition, Valero owns a second 
Delaware River refinery facility that was owned by Motiva Enterprises 
at the time of the reanalysis, but this facility was not considered to 
be a potential project beneficiary. 

[9] The Delaware Terminal--a facility that imports refined petroleum-- 
has since been renamed Magellan Terminal because of a change of 
ownership. 

[10] We received this document from the Corps in January 2010 as our 
work neared its completion. We considered the document in our findings 
but due to reporting time frames we could not comprehensively review 
its economic analysis. 

[11] Under NEPA, federal agencies evaluate the likely environmental 
effects of projects they are proposing using an environmental 
assessment or, if projects are likely to significantly affect the 
environment, a more detailed environmental impact statement. See 42 
U.S.C. § 4332(2)(C), (E). 

[12] According to the agreement, PRPA would also pay an additional 
amount of 10 percent of the total cost of construction of the general 
navigation features. 

[13] Typically, the base year occurs at or near the end of project 
construction. 

[14] The Institute for Water Resources provides the Corps' Civil Works 
program with research and analysis to aid its long-range planning. 

[15] The Corps analyzed a 0.2 percent annual decline in future crude 
oil imports. 

[16] These percentages were the same in the reanalysis's 2004 
supplement and in the 2009 economic update. 

[17] The EIA is the Department of Energy's statistical and analytical 
agency. It is the primary federal government authority on energy 
statistics and analysis. 

[18] An EIA official indicated that imports for 2009 are preliminary 
and subject to revision. 

[19] Pub. L. No. 110-140, §§ 102 (requiring increased average fuel 
economy standards for vehicles), 202 (requiring regulation to ensure 
that, of the transportation fuel sold each year, a certain amount is 
renewable fuels and certain biofuels, including most ethanols), 121 
Stat. 1492. 

[20] According to a Valero representative, as of March 2010 the firm 
was seeking a buyer for the facility. 

[21] At the time of the reanalysis, Motiva maintained the facility's 
access channel at less than the main channel's 40-foot depth, a 
practice that Valero has continued since it acquired the facility. 
This is due to excessive sediment deposit in the facility's access 
channel. 

[22] Moreover, Valero's other Delaware River facility--in Paulsboro, 
New Jersey--was assumed to benefit primarily from the more efficient 
use of vessels rather than reduced lightering because the facility 
avoided lightering during the period of the Corps' reanalysis. 
Instead, the Paulsboro facility was expected to account for most of 
the project's annual benefits associated with increased tanker 
efficiency, such as the ability to load existing vessels more fully or 
switch to larger vessels. However, Valero representatives told us that 
their supply practices have changed since the Corps' reanalysis, with 
the facility now relying more on lightering than before. For this 
reason, it is likely that benefits related to vessel efficiency should 
be reduced for this facility and benefits related to reduced 
lightering should be increased. 

[23] In 2006 OSG acquired Maritrans, the lightering firm whose 
operations were modeled in the Corps' reanalysis. 

[24] According to an OSG official, one of the vessels in the 
lightering fleet at the time of the reanalysis has been replaced by 
its sister ship, which loads more slowly but is otherwise similar to 
the original vessel. 

[25] U.S. Army Corps of Engineers Institute for Water Resources, The 
Implications of Panama Canal Expansion to U.S. Ports and Coastal 
Navigation Economic Analysis (Alexandria, VA: December 2008). 

[26] EIA's 2008 annual energy outlook was released in June 2008--too 
late to have been considered for the Corps' April 2008 economic update. 

[27] In January 2010 we spoke with a representative of the petroleum 
firm--Magellan LP--located at the port of Wilmington, Delaware. He 
indicated that no new Delaware River berth had been constructed but 
that two alternative berths were now being evaluated. According to the 
representative, Magellan LP is in favor of the deepening project, 
which would create certain advantages for the firm. However, the 
firm's pursuit of a Delaware River ship berth is being evaluated 
independently of the deepening. 

[28] PCBs are a family of chemicals that were used in hundreds of 
industrial and commercial applications, such as electric and hydraulic 
equipment; as plasticizers in paints, plastics, and rubber products; 
and in pigments and dyes. PCBs were banned in 1979 and have been 
demonstrated to cause cancer and affect human immune, reproductive, 
and nervous systems. 

[29] New Jersey officials further note that if dredged material is 
found after it is deposited in a federal disposal site to have higher 
levels of contaminants than currently expected by the Corps, changes 
to required treatment or disposal of this material could result in 
considerable federal expense. For more information about New Jersey's 
concerns, see the state's letter to GAO in appendix IV.

National Oceanic and Atmospheric Administration's understanding that 
the Corps had agreed to supplemental coordination and encouraged the 
state and the Corps to coordinate and consult with each other. 

[34] In commenting on a draft of this report, the Department of 
Defense stated that a new subaqueous lands and wetlands permit 
application was submitted to Delaware on March 12, 2010. 

[35] The solicitation was for a single contract for the segment to 
include both maintenance dredging and deepening. According to the 
Corps, the base contract is for maintenance, but there is also an 
option clause that would authorize dredging in the portions of the 
segment necessary to reach 45 feet of depth. 

[36] The states' and environmental groups' lawsuits assert that the 
Corps has not complied with several other laws, such as the Clean Air 
Act, in addition to those discussed here. 

[37] The court stated that Delaware had failed to prove its claim 
related to the state subaqueous lands and wetlands permit under the 
Clean Water Act, that the record supported the Corps' determination 
that no supplemental consistency determination was required under the 
Coastal Zone Management Act, and that the record did not support that 
the Corps' Clean Air Act conformity determination was rational. Del.

Engineers, --F.Supp.2d --, 2010 WL 322171 (D. Del., 2010).

Defense observed that "predecisional disagreements are not uncommon 
during the deliberation process, and serve as a healthy basis for 
resolving differing opinions and reaching sound conclusions."

Needed, [hyperlink, http://www.gao.gov/products/GAO-02-604] 
(Washington, D.C.: June 7, 2002). 

[42] The reanalysis identified five of these refinery facilities 
importing crude oil at six deep-draft terminals as potential project 
beneficiaries. The sixth facility was included in DMA's modeling of 
Delaware River lightering operations but was not considered to be a 
project beneficiary. 

[43] In 2006 Overseas Shipholding Group acquired Maritrans, the 
lightering firm whose operations were modeled in the Corps' reanalysis. 

[44] The primary function of the Waterborne Commerce Statistics Center 
is to collect, process, distribute, and archive vessel trip and cargo 
data. These data are self-reported to the Corps by companies engaged 
in transporting goods on the navigable waters of the United States. 

[45] Total economic first costs include major items such as 
engineering and design, channel dredging, associated costs, and 
interest during construction, but do not include annual operations and 
maintenance of the deeper channel. The Corps' 2009 economic update 
estimated total economic first costs to be $332.5 million. Associated 
costs, including interest, were estimated to account for $34.4 million 
of this total.

GAO's Mission: 

The Government Accountability Office, the audit, evaluation and 
investigative arm of Congress, exists to support Congress in meeting 
its constitutional responsibilities and to help improve the performance 
and accountability of the federal government for the American people. 
GAO examines the use of public funds; evaluates federal programs and
