Overall Funding Totals
President Biden submitted his FY2025 budget request on March 11, 2024. The Administration request includes
$61.265 billion for energy and water development agencies, a decrease of $110 million (less than 1%) below the
FY2024 enacted amount, excluding emergency appropriations, offsets, and adjustments. FY2024 energy and
water development appropriations were included in Division D of the Consolidated Appropriations Act, 2024,
signed into law March 9, 2024 (P.L. 118-42).

Major Issues
Congressionally Directed Funding (Earmarks). For FY2025, the House Appropriations Committee allows
earmark requests within the major USACE and Reclamation accounts, while the Senate Appropriations
Committee allows earmark requests for major USACE, Reclamation, and DOE energy-related accounts. The
explanatory statement for FY2024 included 273 energy and water development earmarks under USACE,
Reclamation, and DOE accounts totaling $1.613 billion.
Recent Supplemental Funding. From FY2018 through FY2025, Congress provided supplemental and emergency
appropriations for E&W agencies. These appropriations were noted in the Administration’s FY2025 budget
justifications and may factor into the congressional debate on FY2025 E&W appropriations. This debate could
include considerations over the amount of regular appropriations that the FY2025 E&W bill should provide, and
whether to rescind or redirect supplemental appropriations.

Energy Efficiency Standards. DOE energy efficiency standards have drawn congressional scrutiny in the 118th
Congress. House amendments were adopted during debate on the FY2024 E&W bill that would have blocked
funds for DOE efficiency rules on furnaces, water heaters, manufactured housing, commercial icemakers, and
room air conditioners, and any regulation with an annual economic impact of more than $100 million. They were
not included in the enacted measure.

Introduction and Overview
Energy and Water Development and Related Agencies appropriations (E&W) bills typically
include funding for civil works activities of the U.S. Army Corps of Engineers (USACE) in the
Department of Defense, in Title I; the Department of the Interior’s Bureau of Reclamation
(Reclamation) and Central Utah Project (CUP), in Title II; the Department of Energy (DOE), in
Title III; and a number of independent agencies, including the Nuclear Regulatory Commission
(NRC) and the Appalachian Regional Commission (ARC), in Title IV. Figure 1 compares the
major components of the E&W appropriations acts from FY2022 through FY2024 and the
FY2024 and FY2025 funding requests. FY2024 E&W appropriations were included in the
Consolidated Appropriations Act, 2024, signed into law March 9, 2024 (P.L. 118-42).
President Biden submitted his FY2025 budget request on March 11, 2024. The Administration
request includes $61.265 billion for energy and water development agencies, a decrease of $110
million (less than 1%) below the FY2024 enacted amount, excluding emergency appropriations,
offsets, and adjustments. DOE funding would rise by $1.659 billion (3%), to $51.906 billion, and
independent agencies by $17 million (3%), to $519 million. USACE would be reduced by $1.483
billion (-17%), to $7.220 billion, and Reclamation and CUP would decline by $304 million
(-16%), to $1.619 billion, excluding adjustments and offsets.1
DOE’s major program areas include energy, science, defense, and environmental management.
The Administration is again proposing to shift some funding in the Energy Efficiency and
Renewable Energy (EERE) appropriations account into several new accounts: the Federal Energy
Management Program (FEMP), the Office of Manufacturing and Energy Supply Chains (MESC),
and the Office of State and Community Energy Programs (SCEP), which provides low-income
weatherization and state planning grants. The total FY2025 request for EERE and the proposed
new accounts is $3.869 billion, an increase of $409 million (12%) over the combined EERE
enacted amount for FY2024. DOE has established separate offices for FEMP, MESC, and SCEP,
but Congress has not approved previous requests to create separate appropriations accounts for
them.
Other energy programs with large proposed percentage increases are the Office of Technology
Transitions, which facilitates the commercialization of new energy technologies, proposed to
increase by 35% in FY2025 to $27 million, and the Office of Clean Energy Demonstrations,
which would rise by 260% to $130 million. The Office of Indian Energy Policy and Programs
would increase by 36% to $95 million, and the Grid Deployment Office would increase by 70%
to $102 million.
Funding for DOE’s Office of Science is proposed to increase by $343 million (4%), to $8.583
billion, under the Administration budget request, with the largest amounts going for Basic Energy
Sciences ($2.582 billion) and High Energy Physics ($1.231 billion). Funding for the National
Nuclear Security Administration (NNSA), which is responsible for nuclear warheads, nuclear
weapons nonproliferation, and naval reactor research and development (R&D), is proposed to
increase by $862 million (4%), to $24.997 billion. Environmental Management (waste
management and cleanup) would decrease by $253 million (-3%), to $8.229 billion.

CPRT-118HPRT55007.pdf. Some appropriations totals for FY2024 have changed from previously calculated amounts
because of re-estimates of revenue offsets and other adjustments.

Energy and Water Development: FY2025 Appropriations

The water agencies in the Energy and Water Development appropriations bill are proposed for
funding reductions under the FY2025 budget request. Discretionary E&W appropriations for
USACE would decline from their FY2024 enacted level by $1.483 billion (-17%), to $7.220
billion. Reclamation (separately from CUP) would be reduced by $301 million (-16%), to $1.599
billion.
Among the independent agencies funded by the bill, NRC would receive an increase in total
appropriations from $944 million in FY2024 to $975 million in FY2025 (up $31 million, or 3%).
NRC’s budget is mostly offset by nuclear industry fees, which may vary from year to year; the
Administration proposed an increase in the agency’s net appropriation from $137 million in
FY2024 to $151 million in FY2025 (up $14 million, or 10%). The funding request for the
Appalachian Regional Commission and other regional authorities in the bill is largely unchanged
from the FY2024 enacted levels.
Additional FY2025 funding for E&W agencies has been appropriated in advance by the
Infrastructure Investment and Jobs Act (IIJA; P.L. 117-58) and the budget reconciliation measure
commonly referred to as the Inflation Reduction Act of 2022 (IRA; P.L. 117-169). For details, see
the section on “Recent Supplemental Funding.”

development agencies, an increase of $2.171 billion (4%) above the enacted FY2023 amount and
$638 billion (-1%) below the request.
DOE received $50.247 billion, an increase of $1.801 billion (4%) over FY2023 and $2.324
billion (-4%) below the request. EERE, including programs that the Administration proposed to
fund under separate accounts, received $3.460 billion, the same as the FY2023 amount and a
decrease of $1.332 billion (-28%) from the equivalent request. Science received $8.240 billion, an
increase of $140 million (2%) over the FY2023 enacted level and $560 million (-6%) below the
request. NNSA received $24.135 billion, an increase of $1.972 billion (9%) over FY2023 and
$290 million (1%) above the request.
USACE received $8.703 billion,2 excluding rescissions and adjustments, which is $393 million
(5%) more than in FY2023 and $1.290 billion (17%) higher than the request. Reclamation and
CUP received $1.923 billion, a reduction of $31 million (-2%) from FY2023 and $454 million
(31%) above the request.
NRC received $944 million, an increase of $17 million (2%) over the FY2023 level and a
decrease of $35 million (-4%) from the request, although the net appropriation was almost the
same as in FY2023. ARC received $200 million, the same as in FY2023 and $35 million (-15%)
below the request. The Great Lakes Authority received first-time funding of $5 million, the
requested amount, while the other regional authorities and commissions received all or slightly
more than the amounts requested. The Northern Border Regional Commission and Delta
Regional Authority each received $1 million more than their FY2024 requested amounts ($41
million and $31.1 million, respectively).

FY2025 Budgetary Limits
Congressional consideration of the annual Energy and Water Development appropriations bill is
affected by certain procedural and statutory budget enforcement requirements. These consist
primarily of procedural limits on discretionary spending (spending provided in annual
appropriations acts) established in a budget resolution or through some other means, and
allocations of this amount that apply to spending under the jurisdiction of each appropriations
subcommittee.
The Fiscal Responsibility Act (FRA, P.L. 118-5), enacted in June 2023, establishes enforceable
discretionary spending limits (caps) for FY2024 and FY2025. For FY2025, the limits are
$895.212 billion for defense and $710.688 billion for nondefense. Spending designated as an
emergency requirement would be exempt up to any amount, while funding for certain purposes—
such as program integrity initiatives, disaster funding, and reemployment services—would be
exempt up to specified amounts.

The House Appropriations Committee approved interim FY2025 allocations on May 23, 2024, for
each of the 12 appropriations subcommittees under Section 302(b) of the Congressional Budget
and Impoundment Control Act of 1974 (P.L. 93-344).3 For the Energy and Water Development
Subcommittee, the interim allocations provide $34.193 billion for defense functions and $24.997
billion for non-defense functions, totaling $59.190 billion. The interim allocation is $1.584 billion
below the Administration’s total request for agencies in the Energy and Water Development bill,
including offsets.

Funding Issues and Initiatives
Several issues have drawn particular attention during congressional consideration of Energy and
Water Development appropriations for FY2025. The issues described in this section—listed
approximately in the order the affected agencies appear in the Energy and Water Development
bill—were selected based on total funding involved, percentage of proposed increases or
decreases, amount of congressional debate engendered, and potential impact on broader public
policy considerations.
Congressionally Directed Funding
The 118th Congress, largely continuing the policies of the 117th Congress, allowed earmarks for
site-specific projects and other activities in the FY2024 appropriations process. These are referred
to as “community project funding” (CPF) in the House and “congressionally directed spending”
(CDS) in the Senate. From the 112th through the 116th Congresses, moratorium policies largely
prohibited earmarks for such projects. Funding for specific water projects constitutes the majority
of the annual budget request for USACE and Reclamation.4 For FY2025, the House and Senate
Appropriations committees invited Members of Congress to request CPF/CDS items,
respectively. The House Appropriations Committee allowed CPF requests within the major
USACE and Reclamation accounts, while the Senate Appropriations Committee allowed CDS
requests for major USACE, Reclamation, and DOE energy-related accounts.5
Figure 2 shows enacted CPF/CDS amounts per agency for FY2022 through FY2024. The
patterned area of the stacked columns distinguishes the sum of the top three CPF/CDS items (all
under USACE appropriations).

additional funding, without identifying specific projects. In the 117th and 118th Congresses, enacted appropriations have
included additional funding for USACE and Reclamation, along with CPF/CDS items.

Recent Supplemental Funding
Congress provided supplemental appropriations for USACE and Reclamation from FY2018
through FY2023 for disaster response and mitigation (e.g., drought, flood); study, construction,
maintenance, and repair of projects; new authorities that expand the agencies’ activities; and
COVID-19 precautions, among other purposes.6 Congress also has provided supplemental
appropriations to DOE for clean energy demonstration projects, science facilities and
infrastructure, hydrogen production and distribution infrastructure, nuclear weapons
nonproliferation, and renewable energy R&D, among other purposes. In addition, in some years,
other agencies funded under Energy and Water Appropriations Acts received supplemental
funding. Table 1 details in nominal dollars supplemental appropriations based on the fiscal year
when funds are first available (in some cases, FY2024-FY2026). All of these funds are available
until expended except for funds from the IRA, which are available through various years from
FY2026 to FY2031, and Defense Nuclear Nonproliferation and Salaries and Expenses in P.L.
118-50, which are available through FY2025.7

The relatively large amount of supplemental funding already available to Energy and Water
Development agencies for FY2024 was a consideration in the congressional debate on FY2024
appropriations. This affected considerations about the amount of regular appropriations to be
provided in the FY2024 E&W bill and the FY2025 Administration request, and whether to fund
activities primarily with previously enacted supplemental appropriations. For example, DOE cited
IIJA funding for two advanced reactor demonstration projects as the reason that no funding for
those projects was included in the FY2025 request.

Proposed Increases for EERE and New Accounts
The Administration’s FY2025 request would increase DOE EERE funding by $409 million (12%)
over the FY2024 enacted amount. This includes separate appropriations accounts that the request
would establish for several large offices currently under the EERE appropriations account—
FEMP, Office of Manufacturing and Energy Supply Chains, and the Office of State and
Community Programs. Congress did not approve moving these appropriations accounts out of
EERE as proposed by the Administration in FY2023 and FY2024.
EERE programs with the largest requested percentage increases are Renewable Energy Grid
Integration (up $43 million, or 195%), Wind Energy Technologies (up $62 million, or 45%),
Geothermal Technologies (up $38 million, or 32%), Industrial Efficiency and Decarbonization
(up $50 million, or 21%),8 and Vehicle Technologies (up $52 million, or 12%).
These increases do not include the efficiency programs that the Administration proposes moving
to separate DOE appropriations accounts. FEMP would receive $64 million in FY2025 under the
request (up $21 million, or 49%), the Office of State and Community Energy Programs, which
handles state energy planning grants and low-income home weatherization assistance, would
receive $574 million (up $103 million, or 22%), and the Office of Manufacturing and Energy
Supply Chains would receive $113 million (up $95 million or 528%).
IIJA appropriated $16.264 billion in FY2022 through FY2026 in additional emergency spending
for programs in the EERE account, of which $1.945 billion was for FY2025.9 EERE programs
received $12.150 billion in additional funding in IRA, available from FY2022 through FY2026,
FY2027, FY2029, or FY2031, depending upon the provision.
For more details, see CRS In Focus IF12376, DOE Office of Energy Efficiency and Renewable
Energy FY2024 Appropriations, by Martin C. Offutt and Corrie E. Clark.
Controversy over Energy Efficiency Standards
DOE revises most of the energy efficiency standards in its Appliance and Commercial Equipment
Standards Program on a six-year cycle. Compliance with the revised standards, typically three
years after publication, can lead to additional costs to industry as manufacturing costs increase,
including up-front capital costs. The revisions generally are estimated to save consumers and
firms money due to lower energy costs over the life of the appliance or equipment. Several
amendments adopted to the House-passed FY2024 Energy and Water Development
appropriations bill (H.R. 4394) would have prohibited or preserved DOE’s ability to revise and/or
implement and enforce these standards, particularly for gas stoves. DOE’s energy efficiency

proposes dividing Advanced Manufacturing into two programs: (1) Advanced Materials and Manufacturing
Technologies and (2) Industrial Efficiency and Decarbonization.

standards were a topic of discussion at the House Appropriations Committee’s FY2025 budget
hearing with Energy Secretary Jennifer Granholm.10
For more information, see CRS Insight IN12115, DOE’s Regulations on Gas Stoves, by Martin C.
Offutt, and CRS Insight IN12179, DOE’s Proposed Regulation on Electricity Distribution
Transformers, by Martin C. Offutt.
Proposed Decreases for Advanced Nuclear Reactors and Fuel
DOE is requesting $1.591 billion for Nuclear Energy, a reduction of $94 million (-6%) from the
FY2024 enacted amount. The largest reductions would be for Reactor Concepts (down $21
million, or -19%) and the Advanced Reactor Demonstration Program (down $98 million, or -
31%). Nuclear Energy Enabling Concepts would increase by $9 million (9%), Fuel Cycle
Research and Development would decrease by $1 million (less than 1%), and University and
Competitive Research Programs would increase by $3 million (2%).
The requested funding for FY2025 is supplemented by larger amounts previously appropriated by
IIJA and IRA. In a transfer from IIJA, the enacted FY2024 E&W appropriations act (Section 311)
provided $950 million for DOE to support up to two small modular reactor demonstrations,
through the Office of Clean Energy Demonstrations, and nuclear reactor safety training. Section
312 provided up to $2.720 billion for DOE to support domestic uranium mining, conversion, and
enrichment, and to support the acquisition of high-assay low-enriched uranium (HALEU) for
advanced reactors. The funds come from the unobligated balance of $6 billion appropriated by
IIJA for the DOE Civil Nuclear Credit program to prevent the closure of existing nuclear power
plants. DOE has conditionally approved $1.1 billion of Civil Nuclear Credits for one plant,
Diablo Canyon in California.11 The transferred IIJA funds are in addition to $700 million
appropriated for establishing a HALEU supply chain by IRA.
Transfers for nuclear fuel supply under Section 312 were contingent on the imposition of
sanctions on enriched uranium imports from Russia, which occurred with the signing of the
Prohibiting Russian Uranium Imports Act on May 13, 2024 (P.L. 118-62, H.R. 1042, H.Rept.
118-296). The law prohibits Russian imports of enriched uranium beginning 90 days after
enactment, although waivers for specified amounts are allowed through the end of 2027.
Many proposed designs for advanced nuclear reactors would require HALEU fuel, which has
higher enrichment of the fissile isotope uranium 235 than that used by existing U.S. nuclear
plants. HALEU is not available in commercial quantities, and the nuclear industry contends that
government action is needed to prevent a “choke point” in advanced reactor development.12 The
latest appropriations in the FY2024 E&W act to support the establishment of a HALEU supply
chain are in addition to $700 million previously appropriated for that purpose by IRA.
Strategic Petroleum Reserve Modernization Program
DOE is currently executing a Strategic Petroleum Reserve (SPR) modernization program that
invests in infrastructure and systems with the goal of extending SPR mission readiness (i.e., oil

drawdown and refill rates) for another 15 to 25 years. According to DOE’s FY2025 budget
justification, the project is scheduled to be completed by the end of FY2026. Estimated program
costs of approximately $1.4 billion were funded through congressionally authorized SPR crude
oil sales conducted between FY2017 and FY2021. Sale proceeds were deposited into the Energy
Security and Infrastructure Modernization (ESIM) Fund, an account used to pay for
modernization program costs.
Citing “pandemic and related supply chain issues, and delays related to” emergency sales that
started in FY2022, estimated program costs are currently $1.92 billion.13 The Biden
Administration requested supplemental funding of $500 million for ESIM in FY2023, but that
request was not approved. DOE’s FY2025 budget justification highlights additional program
costs, lists suspended and deferred projects, and indicates anticipation of nearly $500 million of
additional supplemental funding for FY2024. However, the SPR supplemental funding
subsequently was not requested. Other congressional options for addressing the estimated SPR
modernization funding shortfall could include directing DOE to sell $500 million of crude oil and
deposit sale proceeds into the ESIM fund, rescinding unobligated funds from the SPR Petroleum
Account and transferring those funds to the ESIM account, directing DOE to re-scope the
program to match available funding, or exploring other potential options.
Proposed Increase for the Office of Clean Energy Demonstrations
The Administration requested $180 million in FY2025 for the DOE Office of Clean Energy
Demonstrations (OCED). This would be a $130 million (260%) increase from OCED’s FY2024
regular annual appropriation, but the program’s regular appropriations are overshadowed by
$21.456 billion appropriated for OCED through FY2026 by IIJA (see Table 2). In addition, IRA
appropriated $5.812 billion for an OCED program on Advanced Industrial Facilities Deployment
for FY2022-FY2026.
OCED funds clean energy and industrial decarbonization demonstration projects for potential
commercialization. OCED took over DOE support for two advanced nuclear reactor
demonstration projects in Wyoming and Texas previously overseen by the DOE Office of Nuclear
Energy (NE), but no funding was requested for those projects in FY2025, because “IIJA provided
multi-year funding for these demonstrations,” according to the DOE budget justification.14 As
noted above, the enacted FY2024 E&W measure transferred $800 million from the DOE Civil
Nuclear Credit program to OCED for up to two cost-shared advanced reactor projects with a non-
federal cost share of at least 50%. (For more details, see CRS In Focus IF12636, Nuclear Energy
in a Climate Change Context: Current Appropriations for Nuclear Energy Development, by

Reduction in Crosscutting Hydrogen Funding
The DOE crosscutting hydrogen activity includes several offices with responsibility for
supporting hydrogen work based on different primary sources of energy (e.g., renewable, fossil,
nuclear) and types of end-use (e.g., vehicles, portable power, thermal comfort). DOE’s FY2025
request for crosscutting hydrogen appropriations totals $377 million, a decrease of $19 million , (-
5%) below the FY2024 enacted level of $396 million.15 Most of the hydrogen funding comes
from EERE and Fossil Energy and Carbon Management (FECM), with smaller amounts from the
Office of Nuclear Energy and the Office of Science.
In addition to funding in the Energy and Water Development appropriations bill, IIJA
appropriated $9.500 billion for three hydrogen- and fuel cell-related DOE programs from FY2022
to FY2026 ($1.900 billion in FY2025). The largest of these, the Regional Clean Hydrogen Hubs
in the Office of Clean Energy Demonstrations, was appropriated $8.000 billion to support

demonstration projects involving networks of clean hydrogen producers and consumers, along
with the connecting infrastructure.
DOE launched a “Hydrogen Shot” initiative in June 2021—one of its “Energy Earthshots”
dedicated to the scale-up of emerging low-carbon energy technologies—with a goal of making
hydrogen, produced through electrolysis, commercially available at a cost of $1 for one kilogram
in one decade, not including delivery and dispensing.

Proposed Increase for Weapons Activities, Decrease for Nuclear
Nonproliferation
The FY2025 budget request for DOE Weapons Activities is $19.849 billion—$741 million (4%)
higher than the FY2024 enacted level, while the FY2025 request of $2.119 billion for Naval
Reactors is $173 million (9%) above the FY2024 amount. The FY2025 request for nuclear
Nonproliferation is $2.465 billion, a decrease of $116 million (-4%) from the FY2024
appropriation. All three programs are carried out by NNSA, a semiautonomous agency within
DOE.
Requested FY2025 amounts for nuclear warhead modernization programs in Weapons Activities
include the following:
• $28 million for the B61-12 Life Extension Program (LEP), a decrease of $422
million (-94%) from the FY2024 enacted amount. The B61-12 LEP is to combine
four existing variants of the B61 gravity bomb.
• $16 million for the B61-13 variant of the B61 gravity bomb, a 69% decrease
from the $52 million enacted in FY2024. The Biden Administration announced in
2023 that the United States would pursue this warhead variant utilizing B61-12
production capacities for use against “certain harder and large-area military
targets” as the Department of Defense “works to retire legacy systems such as the
B83-1 and the B61-7.”16
• $79 million for the W88 Alteration, a decrease of $100 million (-56%) from the
FY2024 amount. The program is to upgrade the arming-fuzing-firing system on
the warhead and refresh the warhead’s conventional high explosives. This
warhead is carried on a portion of the D-5 (Trident) submarine-launched ballistic
missiles (SLBMs).
• $1.165 billion for the W80-4 warhead LEP, an increase of $154.82 million (15%)
over the FY2024 enacted amount intended for the warhead that will be mounted
on the Long-Range Standoff (LRSO) cruise missile.
• $1.096 billion for the W87-1 warhead modification program, an increase of $27
million (3%) from FY2024. The Air Force plans to deploy the W87-1 on the new
U.S. Sentinel land-based intercontinental ballistic missile (ICBM).17

• $456 million for the W93 warhead, an increase of $66 million (17%) from the
FY2024 enacted amount. The W93 is a new design intended for deployment on
ballistic missile submarines.
• While the Biden Administration did not include funding for the nuclear sea-
launched cruise missile (SLCM-N) warhead in NNSA’s FY2025 budget request,
NNSA Administrator Jill Hruby testified in a May 2024 hearing that NNSA’s
FY2025 unfunded priorities list includes $70 million in funding for this
warhead.18 The FY2024 enacted amount for this warhead was $70 million.19
NNSA is implementing seven warhead programs while also engaging in intensive efforts to
recapitalize its production infrastructure. In this regard, congressional concern has been raised
about NNSA’s schedule for developing production capacity for plutonium pits (warhead cores),
central components of nuclear warheads. NNSA plans to develop pit production capacity at Los
Alamos National Laboratory in New Mexico and the Savannah River Site (SRS) in South
Carolina. Pit production is included in NNSA’s FY2025 budget under Plutonium Modernization,
for which NNSA requests $2.891 billion for FY2025, a decrease of $20 million (-1%) from the
FY2024 enacted level.
Appropriations for NNSA nuclear weapons activities and other defense programs typically
closely track the levels authorized in annual National Defense Authorization Acts (NDAAs). An
FY2025 NDAA (H.R. 8070) was ordered to be reported by the House Armed Services Committee
on May 22, 2024.
For more information, see CRS Report R47657, Energy and Water Development Appropriations
for Nuclear Weapons Activities: In Brief, by Anya L. Fink and Alexandra G. Neenan.
Startup of Surplus Plutonium Disposition
The FY2025 budget request provides for activities related to the disposition of surplus plutonium,
a key material for nuclear weapons, in the Material Management and Minimization (MMM) and
Nonproliferation Construction accounts. These activities are intended to dilute 34 metric tons of
surplus plutonium, located primarily at SRS, for permanent disposal at the Waste Isolation Pilot
Plant (WIPP), a deep underground repository in New Mexico. “A total of 13 shipments of
downblended surplus plutonium were made to WIPP in FY 2023,” according to DOE’s FY2025
budget justification.20
In the MMM account, DOE is requesting $193 million for Plutonium Disposition and, under the
Construction account, $40 million for the Surplus Plutonium Disposition Project at SRS. The
construction request would be a reduction of $37 million (-48%) from the FY2024 enacted
amount. The budget justification says the construction funding reduction results from “the use of
prior year uncosted balances available due to delays in final design completion.”21 The request

also reflects a 10-year deferral of the expansion of plutonium pit disassembly and processing
capability, which will be needed to complete the disposition of all 34 metric tons of surplus
plutonium.22
Cleanup of Former Nuclear Sites: Adequacy of Proposed Funding
DOE’s Office of Environmental Management (EM) is responsible for environmental cleanup and
waste management at the department’s nuclear facilities. The $8.229 billion request for EM
activities for FY2025 is $253 million (-3%) below the FY2024 enacted level of $8.482 billion,
including adjustments and offsets.
The primary appropriations component of the EM program is the Defense Environmental
Cleanup account, which finances the cleanup of former nuclear weapons production sites. For
FY2025, the Administration requests $7.060 billion, a reduction of $225 million (-3%) from the
FY2024 enacted amount. For the Non-Defense Environmental Cleanup account, which funds the
cleanup of federal nuclear energy research sites, the request is $315 million, a reduction of $27
million (-8%) below the FY2024 enacted level. The third component of the EM budget is the
Uranium Enrichment Decontamination and Decommissioning Fund (UED&D), for which the
FY2025 request is $854 million, nearly the same as the FY2024 enacted amount. This fund was
established by Title XI of the Energy Policy Act of 1992 (P.L. 102-486) to pay for the cleanup of
three federal facilities that enriched uranium for national defense and civilian purposes, located
near Paducah, KY; Piketon, OH (Portsmouth plant); and Oak Ridge, TN.
The adequacy of funding for the Office of Environmental Management to attain cleanup
milestones across the entire site inventory has been a recurring issue. Cleanup milestones are
enforceable measures incorporated into compliance agreements negotiated among DOE, the
Environmental Protection Agency, and the states. These milestones establish time frames for the
completion of specific actions to satisfy applicable requirements at individual sites.
Federal Regional Commissions and Authorities: Amending or
Expanding Uses of Funding
The FY2025 budget request included proposed appropriations language to amend or expand the
use of funding by certain federal regional commissions and authorities (i.e., Delta Regional
Authority (DRA), the Denali Commission, and the Northern Border Regional Commission
(NBRC)). The FY2025 request proposes to repeal the sunset (or termination of authority)
provision for DRA’s authority and allow the DRA to collect and spend fees to cover the costs of
operating a visa sponsorship program.23 The President’s budget would allow funding provided by
the Denali Commission to be considered a non-federal match in projects for which the Denali
Commission is not the primary funding source and proposes that the non-federal cost-share

22 Ibid., p. 628.
23 The FY2025 budget request included proposed appropriations language to repeal section 382N of the Delta Regional
Authority Act of 2000 (7 U.S.C. 2009aa–13). See Office of Management and Budget (OMB), Appendix: Budget of the

Army Corps of Engineers
USACE is an agency in the Department of Defense with both military and civilian
responsibilities. Under its civil works program, which is funded by the Energy and Water
Development appropriations bill, USACE plans, builds, operates, and in some cases maintains
water resource facilities for coastal and inland navigation, riverine and coastal flood risk
reduction, and aquatic ecosystem restoration.26
In recent decades, Congress has generally authorized USACE studies, construction projects, and
other activities in omnibus water authorization bills, typically titled as Water Resources
Development Acts (WRDAs), prior to funding them through appropriations legislation. Recent
Congresses enacted omnibus water resources authorization acts in 2014, 2016, 2018, 2020, and
2022. (The latest WRDA was Title LXXXI of Division H of the James M. Inhofe National
Defense Authorization Act for Fiscal Year 2023, P.L. 117-263.) These acts consisted largely of
authorizations for new USACE studies and projects, and they altered numerous USACE policies
and procedures.27
Unlike for highways and in municipal water infrastructure programs, federal funds for USACE
are not distributed to states or projects based on formulas or delivered via competitive grants.
Instead, USACE generally is directly involved in planning, designing, and managing the
construction of projects that are cost-shared with nonfederal project sponsors.
Policies in the 112th through the 116th Congresses limited congressionally directed funding of site-
specific projects (i.e., earmarks). Prior to the 112th Congress, Congress would direct funds to
specific projects not in the budget request or increase funds for certain projects. For FY2011-
FY2021, Congress appropriated additional funding for categories of USACE work without
identifying specific projects. During that period, after congressional enactment of the

26 Military responsibilities are funded through the Military Construction, Veterans Affairs, and Related Agencies
appropriations bill.

appropriations legislation and accompanying report language on priorities and other guidance for
use of the additional funding, the Administration developed a work plan that reported on (1) the
studies and construction projects selected to receive funding for the first time (new starts) and (2)
the specific studies and projects receiving additional funds. For FY2022 through FY2024,
Congress approved earmarks in specified categories, in addition to providing additional funding
for specific categories for USACE to allocate in work plans.28 House and Senate rules again allow
USACE earmarks for FY2025. For more information, see CRS Report R46320, U.S. Army Corps
of Engineers: Annual Appropriations Process, by Anna E. Normand and Nicole T. Carter.

a. The Consolidated Appropriations Act, 2021, created a new USACE account to support direct loans and for
the cost of guaranteed loans, as authorized by the Water Infrastructure Finance and Innovation Act of 2014
(WIFIA, Title V, Subtitle C of P.L. 113-121).
b. In the Administration’s FY2025 request, as with previous requests, some activities that are funded in the
O&M, Construction, and MR&T accounts are proposed to be funded directly from the Harbor Maintenance
Trust Fund (HMTF) account. That is, the Administration proposes funding eligible USACE activities directly
from the trust fund. This would replace the current practice of having USACE’s O&M, Construction, and
MR&T accounts incur expenses for HMTF-eligible activities, and for these expenses to be reimbursed from
the HMTF accounts. For example, HMTF-eligible maintenance dredging would no longer be funded by the
O&M account and reimbursed by the HMTF; instead, the dredging would be funded directly from the HMTF
account. These proposals were not enacted in FY2024. Similar proposals also were not enacted in FY2019,
FY2020, FY2021, FY2022, and FY2023.
In addition to the regular appropriations for FY2022 and FY2023, USACE received the following
supplemental appropriations:
• $5.711 billion in Division B of P.L. 117-43;
• $14.969 billion for FY2022, $1.080 billion for FY2023, and $1.050 billion for
FY2024 in the IIJA (P.L. 117-58);
• $1.480 billion in Division N of P.L. 117-328;29 and
• $20 million in the FY2023 continuing resolution (P.L. 117-180).
For more information on USACE supplemental funding, see CRS In Focus IF11945, U.S. Army
Corps of Engineers: Supplemental Appropriations, by Anna E. Normand and Nicole T. Carter.
Bureau of Reclamation and Central Utah Project
Most of the large dams and water diversion structures in the West were built by, or with the
assistance of, the Bureau of Reclamation. While USACE built hundreds of flood control and
navigation projects, Reclamation’s original mission was to develop water supplies, primarily for
irrigation to reclaim arid lands in the West for farming and ranching. Reclamation has evolved
into an agency that assists in meeting the water demands in the West while working to protect the

29 Of the $1.480 billion in emergency supplemental funds provided by the Disaster Relief Supplemental Appropriations
Act, 2023 (Division N of P.L. 117-328), $350 million was made available for USACE to allocate in a work plan for
construction and O&M of certain categories of projects (i.e., similar to additional funding provided through annual
appropriations in FY2014-FY2022). USACE allocated the $350 million from Division N along with additional funding
provided by Division D in its FY2023 work plans.

environment and the public’s investment in Reclamation infrastructure. The agency’s municipal
and industrial water deliveries have more than doubled since 1970.
Today, Reclamation manages hundreds of dams and diversion projects, including more than 300
storage reservoirs, in 17 western states. These projects provide water to approximately 10 million
acres of farmland and 31 million people. Reclamation is the largest wholesale supplier of water in
the 17 western states and the second-largest hydroelectric power producer in the nation.
Reclamation facilities also provide substantial flood control, recreation, and other benefits.
Reclamation facility operations are often controversial, particularly for their effect on fish and
wildlife species and because of conflicts among competing water users during drought conditions.
As with USACE, the Reclamation budget is made up largely of individual project funding lines,
rather than general programs that would not be covered by congressional earmark requirements.
Therefore, as with USACE, these Reclamation projects have often been subject to earmark
disclosure rules. The moratorium on earmarks through FY2021 restricted congressional steering
of money directly toward specific Reclamation projects. For FY2022 through FY2025, the rules
again have allowed congressionally directed funding for specific Reclamation projects.
Reclamation’s single largest account, Water and Related Resources, encompasses the agency’s
traditional programs and projects, including construction, operations and maintenance, dam
safety, and ecosystem restoration, among others.30 Reclamation also typically requests funds in a
number of smaller accounts, and has proposed additional accounts in recent years.
Implementation and oversight of CUP, also funded by Title II, is conducted by a separate office
within the Department of the Interior.31

Appropriations, by Charles V. Stern, and CRS In Focus IF12127, Bureau of Reclamation: FY2023

distributes receipts related to a number of federal activities (including royalties received from oil and gas leasing on
federal lands). For more on this fund and financing of selected Reclamation Projects, see CRS Report R41844, The
Reclamation Fund: A Primer, by Charles V. Stern.
31 The Central Utah Project moves water from the Colorado River basin in eastern Utah to the western slopes of the
Wasatch Mountain range. It was authorized in 1956 under the Colorado River Storage Project Act (P.L. 84-485). For

IIJA provided $1.660 billion in additional funding for each of FY2022 through FY2026 for
Reclamation’s Water and Related Resources account. (For more information, see CRS Report
R47032, Bureau of Reclamation Provisions in the Infrastructure Investment and Jobs Act (P.L.
117-58), by Charles V. Stern and Anna E. Normand.) IRA also appropriated additional funds in
FY2022 for Reclamation: $4.000 billion for drought mitigation, available through FY2026; $550
million for disadvantaged communities, available through FY2031; $25 million for projects to
cover water conveyance facilities with solar panels, available through FY2031; and $13 million
for drought relief actions to mitigate drought impacts for tribes affected by the operation of a
Reclamation water project, available through FY2031.
Department of Energy
The Energy and Water Development appropriations bill has funded all DOE programs since
FY2005. Major DOE activities are authorized under multiple energy statutes and include the
following:
• R&D on renewable energy, energy efficiency, nuclear power, fossil energy, and
electricity;
• nuclear weapons and nonproliferation;
• general science;
• environmental cleanup;
• energy statistics, projections, and analysis;
• loan programs;
• the Strategic Petroleum Reserve; and
• power marketing administrations.

Energy Efficiency and Renewable Energy
DOE’s Office of Energy Efficiency and Renewable Energy conducts R&D on transportation
energy technology, energy efficiency in buildings and manufacturing processes, and the
production of solar, wind, geothermal, and other renewable energy.
The Sustainable Transportation program area includes electric vehicles (EVs), vehicle efficiency,
hydrogen and fuel cells, and alternative fuels. Goals of the electric vehicle program include “to
reduce EV battery cell cost to achieve EV cost parity with internal combustion engine (ICE)
vehicles through expanded R&D focused on lithium metal, solid state, and next generation
lithium-ion battery technologies” and to “reduce or eliminate dependence on critical materials
such as cobalt, nickel, and graphite.”33
Renewable power programs focus on electricity generation from solar, wind, water, and
geothermal sources. They are also developing concentrated solar technologies to produce high-

temperature heat that could replace fossil fuels in steel manufacturing and other industrial
processes.
In the energy efficiency program area, the advanced manufacturing program focuses on
improving the energy efficiency of manufacturing processes and on the manufacturing of energy-
related products. The building technologies program includes R&D on lighting, space
conditioning, windows, and control technologies to reduce building energy-use intensity.
The Biden Administration has split several EERE programs into separate offices and is requesting
separate appropriations accounts for them:
• State and Community Energy Programs, which provides two types of formula
grants to states: weatherization grants for improving the energy efficiency of low-
income housing units and state energy planning grants. For more details on
energy efficiency grants, see CRS Report R46418, The Weatherization Assistance
Program Formula, by Corrie E. Clark and Lynn J. Cunningham.
• Manufacturing and Energy Supply Chains, which provides support for increasing
U.S. manufacturing capacity for critical energy technologies and for increasing
industrial energy efficiency.
• Federal Energy Management Program, which provides guidance and expertise to
federal agencies to meet federal goals on energy use and emissions.
Electricity Delivery, Cybersecurity, Energy Security, and Energy Reliability
The Office of Electricity (OE) “leads the Department of Energy’s research, development, and
demonstration programs to strengthen and modernize our nation’s power grid so that our nation
maintains a reliable, resilient, and secure electricity delivery infrastructure” according to the OE
website.34
OE uses a model of North American energy vulnerabilities for analyzing transmission and other
energy infrastructure needs. Other activities include pursuing megawatt-scale electricity storage,
integrating electric power system sensing technology, and analyzing electricity-related policy
issues. A separate DOE Grid Deployment Office supports modernization of the nation’s
electricity transmission system and critical generating facilities through planning and financial
assistance.
The Office of Cybersecurity, Energy Security, and Emergency Response (CESER) is the federal
government’s lead entity for energy sector-specific responses to energy security emergencies—
whether caused by physical infrastructure problems or by cybersecurity issues. The office
conducts R&D on energy infrastructure security technology; provides energy sector security
guidelines, training, and technical assistance; and enhances energy sector emergency
preparedness and response.
Nuclear Energy
DOE’s Office of Nuclear Energy (NE) supports R&D on technologies to improve the efficiency
and economic viability of existing U.S. nuclear power plants, development and demonstration of
advanced reactor technologies, and R&D on nuclear fuel cycle technologies. NE also is issuing
contracts to support growth of the U.S. nuclear fuel supply chain, including uranium mining,
conversion to uranium hexafluoride, and enrichment.

Energy and Water Development: FY2025 Appropriations

The Reactor Concepts program area comprises research on advanced reactors, including
advanced small modular reactors, and research to enhance the “sustainability” of existing
commercial light water reactors. Advanced reactor research focuses on “Generation IV” reactors,
as opposed to the existing fleet of commercial light water reactors, which are generally classified
as Generations II and III.
The Fuel Cycle Research and Development program includes generic research on nuclear waste
management and disposal. One of the program’s primary activities is the development of
technologies to separate the radioactive constituents of spent fuel for reuse or solidifying into
stable waste forms. Other major research areas in the Fuel Cycle R&D program include the
development of accident-tolerant fuels for existing commercial reactors, evaluation of fuel cycle
options, and development of improved technologies to prevent diversion of nuclear materials for
weapons. The program is also developing sources of HALEU, in which uranium is enriched to
between 5% and 20% in the fissile isotope U-235, for potential use in advanced reactors. HALEU
would be required for several designs currently receiving cost-shared support by DOE’s
Advanced Reactor Demonstration Program. For more information, see CRS Report R45706,
Advanced Nuclear Reactors: Technology Overview and Current Issues, by Mark Holt.
Fossil Energy and Carbon Management
The Office of Fossil Energy and Carbon Management (FECM) has historically supported
research related to coal, natural gas, and petroleum,35 including a major focus area on the
development of carbon capture and storage technologies for use with coal-fired power plants. The
office also supports operations at the National Energy Technology Laboratory.
Under the Biden Administration, FECM has shifted its focus to what it calls carbon management.
This includes a focus on development of carbon capture, utilization, and storage technologies,
hydrogen technologies, and options to reduce methane emissions from fossil fuel infrastructure.
FECM also leads DOE’s activities related to critical minerals and rare earth elements.
Additionally, FECM is involved in a number of programs funded by IIJA, either managing the
programs directly or consulting with other DOE offices that have the lead management role.
These programs include Regional Direct Air Capture Hubs, Carbon Storage Validation and
Testing, Critical Mineral Innovation Efficiency, and Alternatives, and the Carbon Dioxide
Transportation Infrastructure Finance and Innovation Act (CIFIA).
FECM’s current carbon capture research focuses on natural gas-fired power plants and
applications outside the power sector, in line with congressional direction provided in the Energy
Act of 2020 (Division Z of P.L. 116-260) and other recent laws. FECM also focuses on research
into producing hydrogen from fossil fuels and using hydrogen in the power sector.
For more information, see CRS In Focus IF11861, DOE’s Carbon Capture and Storage (CCS)
and Carbon Removal Programs, by Ashley J. Lawson; CRS In Focus IF12163, Department of
Energy Funding for Hydrogen and Fuel Cell Technology Programs FY2022, by Martin C. Offutt;
and CRS Report R44902, Carbon Capture and Sequestration (CCS) in the United States, by
Angela C. Jones and Ashley J. Lawson.

35 The Biden Administration renamed the Office of Fossil Energy as the Office of Fossil Energy and Carbon
Management in 2021. This name change was also adopted by appropriators throughout the FY2022 appropriations
process. See DOE, “Our New Name Is Also a New Vision,” July 8, 2021, https://www.energy.gov/fe/articles/our-new-

Energy and Water Development: FY2025 Appropriations

Strategic Petroleum Reserve (SPR)
Authorized in 1975 by the Energy Policy and Conservation Act (P.L. 94-163, as amended; 42
U.S.C. §§6201 et seq.), the SPR fulfills two statutory policy objectives: (1) reduce the economic
impact of oil supply disruptions, and (2) carry out U.S. obligations under the Agreement on an
International Energy Program (IEP)—a multilateral, voluntary agreement subject to international
law. Currently, the SPR consists of a government-owned crude oil reserve in Texas and
Louisiana.36
Since the SPR was established, various administrations have directed crude oil drawdowns and
sales on four occasions in response to emergency oil supply disruptions. During FY2022 and
FY2023, emergency SPR authorities addressed anticipated oil supply disruptions following
Russia’s military invasion of Ukraine. The Biden Administration sold approximately 180 million
barrels between March 2022 and January 2023, the largest-ever emergency SPR release.37 More
frequently, DOE uses SPR authorities to exchange crude oil with refiners and traders following
natural disasters (i.e., hurricanes) and other regional supply disruption events. From time to time,
DOE also activates exchange authorities to temporarily store crude oil during low-price periods
and provide additional supply during high-price periods.38
Because of limited utilization in response to emergency oil supply disruptions prior to the 2022
Ukraine war, growing U.S. crude oil production, and rapidly declining net petroleum imports—
the basis for determining IEP emergency oil stock obligations—Congress began mandating SPR
crude oil sales to pay for other legislative priorities. Between 2015 and 2021, Congress enacted
eight laws mandating the sale of 358.6 million barrels of crude oil. Congress cancelled 140
million barrels of these mandated sales in the Consolidated Appropriations Act, 2023 by
rescinding some proceeds from emergency sales in FY2022 and FY2023. Additionally, Congress
required DOE to sell approximately $1.5 billion of SPR crude oil to pay for an SPR
modernization program.39
Science
The DOE Office of Science conducts basic research in six program areas: advanced scientific
computing research, basic energy sciences, biological and environmental research, fusion energy
sciences, high-energy physics, and nuclear physics. According to DOE’s FY2025 budget
justification, the Office of Science “is the Nation’s largest Federal sponsor of basic research in the
physical sciences and the lead Federal agency supporting fundamental scientific research for our
Nation’s energy future.”40

36 Congress directed DOE to sell and close the 1 million barrel Northeast Gasoline Supply Reserve (NGSR) during
FY2024 (P.L. 118-42, Section 308). DOE issued an NGSR notice of sale in May 2024 and plans to complete the sale in
June 2024.

DOE’s Advanced Scientific Computing Research (ASCR) program focuses on developing and
maintaining computing and networking capabilities for science and research in applied
mathematics, computer science, and advanced networking. The program plays a key role in the
DOE-wide effort to advance the development of exascale computing, with the first exascale
system starting operation at Oak Ridge National Laboratory in May 2022.41
Basic Energy Sciences (BES), the largest program area in the Office of Science, focuses on
understanding, predicting, and ultimately controlling matter and energy at the electronic, atomic,
and molecular levels. The program supports research in disciplines such as condensed matter and
materials physics, chemistry, and geosciences. BES also provides funding for scientific user
facilities (e.g., the National Synchrotron Light Source II, and the Linac Coherent Light Source-
II), and certain DOE research centers and hubs (e.g., Energy Frontier Research Centers, as well as
the Batteries and Energy Storage and Fuels from Sunlight Energy Innovation Hubs).
Biological and Environmental Research (BER) seeks a predictive understanding of complex
biological, climate, and environmental systems across a continuum from the small scale (e.g.,
genomic research) to the large (e.g., Earth systems and climate). Within BER, Biological Systems
Science focuses on plant and microbial systems, while Biological and Environmental Research
supports climate-relevant atmospheric and ecosystem modeling and research. BER facilities and
centers include four Bioenergy Research Centers and the Environmental Molecular Science
Laboratory at Pacific Northwest National Laboratory.42
Fusion Energy Sciences (FES) seeks to increase understanding of the behavior of matter at very
high temperatures and to establish the science needed to develop a fusion energy source. FES
provides funding for the ITER project, a multinational effort to design and build an experimental
fusion reactor.43
The High Energy Physics (HEP) program conducts research on the fundamental constituents of
matter and energy, including studies of dark energy and the search for dark matter. Nuclear
Physics supports research on the nature of matter, including its basic constituents and their
interactions. A major project in the Nuclear Physics program is the construction of the Electron-
Ion Collider at Brookhaven National Laboratory in Upton, NY.
Two significant research efforts in the Office of Science cut across multiple program areas:
quantum information science, which aims to use quantum physics to process information, and
artificial intelligence and machine learning, which use computerized systems that work and react
in ways commonly thought to require intelligence.

Advanced Research Projects Agency–Energy (ARPA-E)
ARPA-E is a DOE office authorized by the America COMPETES Act (P.L. 110-69) to support
transformational energy technology research projects. DOE budget documents describe ARPA-
E’s mission as overcoming long-term, high-risk technological barriers to the development of
energy technologies. According to DOE, since 2009 ARPA-E has provided $3.84 billion in R&D
funding to 1,590 projects, and 235 project teams have raised more than $12.6 billion in private
sector follow-on funding.44
Clean Energy Demonstrations
DOE’s Office of Clean Energy Demonstrations (OCED) funds cost-shared demonstrations of
clean energy technologies, including “clean hydrogen, carbon management, industrial
decarbonization, advanced nuclear reactors, long-duration energy storage, demonstration projects
in rural or remote areas and on current and former mine land, and more.”45 OCED’s portfolio
includes the Advanced Reactor Demonstration Program (transferred from the Office of Nuclear
Energy), which is funding two 50% cost-shared advanced reactor demonstrations in Wyoming
and Texas. OCED also supports the regional Hydrogen Hubs established by IIJA to establish
hydrogen supply chains for industrial, transportation, and other decarbonization uses.
Loan Programs Office
DOE’s Loan Programs Office (LPO) administers several authorized programs that provide loan
guarantees and direct loans to eligible projects, including the following:
• Title 17 Incentives for Innovative Technologies (clean energy loan guarantees);
• Advanced Technology Vehicles Manufacturing (direct loans);
• Tribal Energy Financing (loan guarantees and direct loans); and
• Carbon Dioxide Transportation Infrastructure Finance and Innovation Act
(CIFIA) financing (loan guarantees and direct loans).
As with all federal credit programs, estimated costs to the federal government must be calculated
for each approved project and paid for prior to financial closing. Commonly referred to as “credit
subsidy costs,” estimated costs are typically paid using congressionally appropriated funds, but in
some cases can be wholly or partially paid by the project applicant. Most LPO programs have
available appropriations for credit subsidy costs from previously enacted legislation. The FY2025
budget justification does not request credit subsidy appropriations. Rather, the FY2025 budget
requests appropriations for estimated administrative expenses during the fiscal year, some of
which are offset by collected fees.
Title 17 Incentives for Innovative Technologies
Title XVII of the Energy Policy Act of 2005 (P.L. 109-58) established the clean energy loan
guarantee program by authorizing DOE to guarantee loans for projects located in the United
States that (1) generally avoid or reduce air pollutants or greenhouse gas emissions, and (2)
incorporate new or significantly improved technology. As amended at 42 U.S.C. §16511 et seq.,
the original Title 17 program (Section 1703) includes an expanded list of eligible project
categories as well as opportunities to guarantee loans for projects that employ commercially

available technologies. The IRA provided $40 billion of new lending authority for Section 1703
and appropriated $3.6 billion for credit subsidy and other program-related costs. The IRA also
established a new loan guarantee authority (Section 1706) for “Energy Infrastructure
Reinvestment Financing” aimed at reducing emissions from operating energy infrastructure and
through investments in energy infrastructure that has ceased operations. Section 1706 lending
authority is currently $250 billion, and the IRA appropriated $5 billion to pay for credit subsidy
and related program costs. IRA lending authorities and appropriations for 1703 and 1706 expire at
the end of FY2026. For additional background about Title 17 and IRA amendments to the
program, see CRS Insight IN11984, Inflation Reduction Act of 2022 (IRA): Department of Energy
Loan Guarantee Programs, by Phillip Brown.
Advanced Technology Vehicles Manufacturing
Section 136 of the Energy Independence and Security Act of 2007 (P.L. 110-140) established an
incentive program for manufacturing advanced technology light duty vehicles, including direct
loans for qualified facilities in the United States that manufacture advanced technology vehicles,
components for those vehicles, and engineering integration of qualifying vehicles and
components. As amended at 42 U.S.C. §17013, advanced technology vehicles currently include
medium and heavy-duty vehicles, trains and locomotives, maritime vessels, aircraft, and
hyperloop technology. The IRA appropriated $3 billion to pay for the costs of providing ATVM
direct loans. IRA funds are available until the end of FY2028.
Tribal Energy Financing
Section 2602 of the Energy Policy Act of 1992 (P.L. 102-46), as amended by EPACT05 (P.L. 109-
58) authorized DOE to provide loan guarantees for energy tribal energy development, including
conventional and clean energy projects. As further amended at 25 U.S.C. §3502(d), borrowers are
permitted to receive loan guarantees directly from the U.S. Treasury’s Federal Financing Bank.
The IRA permanently increased lending authority for this program to $20 billion and appropriated
$75 million carry out the program. IRA appropriations expire at the end of FY2028. For
additional information about tribal energy financing, see CRS In Focus IF11793, Indian Energy
Programs at the Department of Energy, by Corrie E. Clark, Mark Holt, and Lexie Ryan.
Carbon Dioxide Transportation Infrastructure Finance and Innovation Act
(CIFIA) Financing
Section 40304 of the Infrastructure Investment and Jobs Act (IIJA, P.L. 117-58; as amended at 42
U.S.C. §16371) established the CIFIA program to provide grants and federal credit (i.e., direct
loans or loan guarantees) for common carrier infrastructure projects or associated equipment that
will transport carbon dioxide captured from anthropogenic CO2 emission sources or from ambient
air. LPO coordinates with DOE’s Office of Fossil Energy and Carbon Management (FECM) to
execute the CIFIA program. The IIJA appropriated $2.1 billion for the CIFIA program.
Energy Information Administration
The U.S. Energy Information Administration (EIA) was established within DOE as the lead
federal agency for collecting, analyzing, and disseminating data on U.S. and world energy supply
and consumption. EIA data collection spans the energy system from supply and transport to
consumption. All energy sources are included in EIA’s data and analysis products, though some
(e.g., petroleum) are more detailed than others (e.g., renewables). Recent areas of congressional
interest include improvements to EIA’s computer models used to project U.S. energy supply and

commercial buildings and by cryptocurrency miners. For more details, see CRS Report R46524,
The U.S. Energy Information Administration, coordinated by Ashley J. Lawson.
Nuclear Weapons Activities
In the absence of explosive testing of nuclear weapons, the United States has adopted a science-
based program to maintain and sustain confidence in the reliability of the U.S. nuclear stockpile.
Congress established the Stockpile Stewardship Program in the National Defense Authorization
Act for Fiscal Year 1994 (P.L. 103-160). The goal of the program, as amended by the National
Defense Authorization Act for Fiscal Year 2010 (P.L. 111-84, §3111), is to ensure “that the
nuclear weapons stockpile is safe, secure, and reliable without the use of underground nuclear
weapons testing.” The program is operated by NNSA, a semiautonomous agency within DOE
established by the National Defense Authorization Act for Fiscal Year 2000 (P.L. 106-65, Title
XXXII). NNSA implements the Stockpile Stewardship Program through the activities funded by
the Weapons Activities account in the NNSA budget.
Most of NNSA’s weapons activities take place at the nuclear weapons complex, which consists of
three laboratories (Los Alamos National Laboratory, NM; Lawrence Livermore National
Laboratory, CA; and Sandia National Laboratories, NM and CA); four production sites (Kansas
City National Security Campus, MO; Pantex Plant, TX; Savannah River Site, SC; and Y-12
National Security Complex, TN); and the Nevada National Security Site (formerly the Nevada
Test Site). NNSA manages and sets policy for the weapons complex; contractors to NNSA
operate the eight sites. Radiological activities at these sites are subject to oversight and
recommendations by the independent Defense Nuclear Facilities Safety Board, funded by Title IV
of the annual Energy and Water Development appropriations bill.
NNSA’s budget has four major Weapons Activities program areas:
• Stockpile Management supports work directly on nuclear weapons. These include
life extension programs, warhead surveillance, maintenance, and other activities.
• Production Modernization programs focus on maintaining and expanding the
production capabilities for the components of nuclear weapons that are critical to
weapons performance. According to NNSA, these include primaries, canned
subassemblies, radiation cases, and non-nuclear components.
• Stockpile Research, Technology, and Engineering provides the scientific and
technical foundation for science-based stockpile decisions.
• Infrastructure and Operations maintains, operates, and modernizes the NNSA
infrastructure. It supports construction of new facilities and funds deferred
maintenance in older facilities.
Nuclear Weapons Activities also has several smaller programs, including the following:
• Secure Transportation Asset, providing for safe and secure transport of nuclear
weapons, components, and materials;
• Defense Nuclear Security, providing operations, maintenance, and construction
funds for protective forces, physical security systems, personnel security, and
related activities; and
• Information Technology and Cybersecurity, whose elements include
cybersecurity, secure enterprise computing, and Federal Unclassified Information
Technology.

Defense Nuclear Nonproliferation
DOE’s nonproliferation and national security programs provide technical capabilities to support
U.S. efforts to prevent, detect, and counter the spread of nuclear weapons worldwide. These
programs are administered by NNSA’s Office of Defense Nuclear Nonproliferation (DNN).
• The Materials Management and Minimization program conducts activities to
minimize and, where possible, eliminate stockpiles of weapons-useable material
around the world, such as conversion of reactors that use highly enriched
uranium (useable for weapons) to low-enriched uranium.
• Global Materials Security works to increase the security of vulnerable stockpiles
of nuclear material in other countries, promotes the worldwide removal,
reduction, and security of radioactive sources (typically used in medical and
industrial devices), and improves the capability of other countries to halt illicit
trafficking of nuclear materials.
• The Nonproliferation and Arms Control program conducts reviews of nuclear
export applications and technology transfer authorizations, implements treaty
obligations, and analyzes nonproliferation policies and proposals.
• Defense Nuclear Nonproliferation Research and Development (DNN R&D)
advances U.S. capabilities to detect and characterize threats such as foreign
nuclear material and weapons production, diversion of special nuclear material,
and nuclear detonations.
• The Nonproliferation Construction program disposes of excess U.S. weapons
plutonium through a “dilute and dispose” strategy.
This account also includes the Nuclear Counterterrorism and Incident Response Program
(NCTIR), which evaluates nuclear and radiological threats and develops emergency preparedness
plans, including organizing scientific teams to provide rapid response to nuclear or radiological
incidents or accidents worldwide.

Cleanup of Former Nuclear Weapons Production and Research Sites
The development and production of nuclear weapons since the beginning of the Manhattan
Project during World War II resulted in a waste and contamination legacy managed by DOE that
continues to present substantial challenges.46 DOE also manages legacy environmental
contamination at sites used for nondefense nuclear research. In 1989, DOE established the Office
of Environmental Management primarily to consolidate its responsibilities for the cleanup of
former nuclear weapons production sites that had been administered under multiple offices.47

46 As described by the Manhattan Project National Historical Park, “The Manhattan Project was a massive, top secret
national mobilization of scientists, engineers, technicians, and military personnel charged with producing a deployable
atomic weapon during World War II. Coordinated by the US Army, Manhattan Project activities were located in
numerous locations across the United States.” The nuclear weapons activities begun by the Manhattan Project are now
the responsibility of DOE. See National Park Service, Manhattan Project National Historical Park website,
https://www.nps.gov/mapr/learn/historyculture/index.htm.
47 In 1989, DOE created the Office of Environmental Restoration and Waste Management, which later was renamed the
Office of Environmental Management.

DOE has identified more than 100 separate sites in over 30 states that historically were involved
in the production of nuclear weapons and nuclear energy research for civilian purposes.48
Responsibility for long-term stewardship at sites where remediation is complete or remedies are
in place is transferred from EM to the separate DOE Office of Legacy Management (LM) and
other offices within DOE.49 Some of the smaller sites for which DOE initially was responsible
were transferred to the Army Corps of Engineers in 1997 under the Formerly Utilized Sites
Remedial Action Program (FUSRAP). Once USACE completes the cleanup of a FUSRAP site, it
is transferred back to LM, which has its own DOE funding subaccount within Other Defense
Activities.
Power Marketing Administrations
DOE’s four Power Marketing Administrations (PMAs) were established to sell the power
generated by various federal dams. The PMAs operate in 34 states; their assets consist primarily
of transmission infrastructure in the form of more than 33,000 miles of high voltage transmission
lines and 587 substations. PMA customers are responsible for repaying all power program
expenses, plus the interest on capital projects. Since FY2011, power revenues associated with the
PMAs have been classified as discretionary offsetting receipts (i.e., receipts that are available for
spending by the PMAs), thus the agencies are sometimes noted as having a “net-zero” spending
authority. Only the capital expenses of the Western Area Power Administration (WAPA) and
Southwestern Power Administration (SWPA) are supported by appropriations from Congress.
Independent Agencies
Independent agencies that receive funding in Title IV of the Energy and Water Development bill
include NRC, ARC, and the Defense Nuclear Facilities Safety Board. NRC receives the largest
funding of these independent agencies. However, about 85% of NRC’s budget is offset by fees, so
that the agency’s net appropriation is less than half of the total funding in Title IV. NRC and ARC
are discussed in more detail below. The recent appropriations history and the FY2024 and
FY2025 budget requests for all the Title IV agencies is shown in Table 13. Additional FY2025
appropriations were provided by the IIJA for ARC and other regional commissions and
authorities as shown in Table 14.

48 For a list of active and completed sites, see the EM “Cleanup Sites” web page and interactive map at
http://energy.gov/em/cleanup-sites.
49 The Office of Legacy Management administers the long-term stewardship of DOE sites that do not have a continuing
mission once cleanup remedies are in place. Sites that have a continuing mission are transferred to the DOE offices that
administer those missions, which are responsible for their long-term stewardship.

Appalachian Regional Commission
Established in 1965,50 ARC is a regional economic development agency. It awards grants and
contracts to state and local governments and nonprofit organizations to foster economic
opportunities, improve workforce skills, build critical infrastructure, strengthen natural and
cultural assets, and improve leadership skills and capacity in the region. ARC’s authorizing
statute defines the Appalachian Region as including all of West Virginia and parts of Alabama,
Georgia, Kentucky, Maryland, Mississippi, New York, North Carolina, Ohio, Pennsylvania,
South Carolina, Tennessee, and Virginia. More than 25 million people currently live in the region
as defined.
ARC provides funding to several hundred projects each year, with particular focus on the region’s
most economically distressed counties. Major areas of infrastructure support include broadband
communication systems, transportation, and water and wastewater systems. ARC has supported
establishment of the Appalachian Development Highway System (ADHS), a planned 3,000-mile
system of highways that connect with the U.S. Interstate Highway System. According to ARC,
91.1% of ADHS is “under construction or open to traffic.”51
Since FY2016, Congress has appropriated approximately $50 million per year as a set-aside for
ARC’s POWER Initiative (Partnerships for Opportunity and Workforce and Economic
Revitalization), which assists communities impacted by the decline of the coal industry. In
FY2024,52 Congress directed ARC to allocate $65 million to the POWER Initiative. The POWER
Initiative funds a variety of economic, workforce, and community development projects to
stabilize and stimulate economic activity in affected communities.

Nuclear Regulatory Commission
NRC is an independent agency that establishes and enforces safety and security standards for
nuclear power plants and users of nuclear materials. Major appropriations and budget request
categories for NRC are shown in Table 15. Nuclear Reactor Safety is NRC’s largest program and
is responsible for licensing and regulating the 94 power reactors in the United States. NRC is also
responsible for licensing and regulating nuclear waste facilities, such as the proposed
underground nuclear waste repository at Yucca Mountain, NV (which has received no new
appropriations since FY2010).
NRC is required by law to offset its total annual appropriation, excluding specified items, through
fees charged to nuclear reactor owners and other holders of NRC licenses. NRC does not retain
the fee revenue, but instead sends it to the U.S. Treasury. Budget items excluded from fee
recovery include prior-year balances, development of advanced reactor regulations, international
activities, and non-site-specific homeland security. As a result, NRC’s net appropriation is about
15% of the agency’s total budget.
