income families to reduce their energy consumption by making their dwellings more energy

efficient. The WAP was authorized in Title IV of the Energy Conservation and Production Act
Lynn J. Cunningham
(ECPA, P.L. 94-385) and established in 1976. This act authorized the Administrator of the
Senior Research Librarian
Federal Energy Administration (and later the Secretary of Energy) to provide weatherization

assistance.

The WAP is a formula grant program: funding flows from DOE to state and territorial
governments and then to local governments and weatherization agencies. DOE program guidelines specify that a variety of
energy efficiency measures are eligible for support under the program. The measures in clude insulation, space-heating
equipment, energy-efficient windows, water heaters, and efficient air conditioners.
Program funds are allocated to the states and territories according to a formula that has a long and complicated history.
Initially WAP funds were distributed in a manner that was more favorable to colder-weather states. This focus was in part the
result of high heating oil prices throughout the 1970s. As WAP was reauthorized, Congress amended the factors that were
considered by DOE to inform the distribution of funds.
The current procedure dates to 1990, when Congress reauthorized WAP. The reauthorization required that the Secretary of
DOE amend the formula allocation to use more recent data and to account for factors such as the cost of heating and cooling.
The effect of these changes was that, in general, some funding would be shifted from colder-weather states to warmer-
weather states. To prevent a dramatic shift of funds, the “new” formula, which DOE developed in 1995, is used to calculate
state allotments only when appropriations for the WAP program exceed approximately $209.7 million. When funds are at or
above the threshold, DOE determines program allocations for states and territories according to a base allocation and a
formula allocation. The base allocation is a set amount for each state and territory and reflects historical program allocations.
The formula allocation is composed of three factors: a population factor, a climatic factor (which is derived from heating and
cooling degree days), and a residential energy expenditure factor by low-income households (which approximates the
financial burden to low-income households of energy use). For total program allocations below $209,724,761, DOE
determines allocations for states and territories according to a base allocation of $209,724,761 less the percentage decrease of
the total program allocation from the threshold.
Under the current procedure, the method of funding allocation is dependent upon whether WAP’s annual appropriation by
Congress is at or exceeds the monetary threshold, as noted. In FY2021, the threshold for the formula allocation was exceeded
with WAP funding at $310 million.
The WAP was reauthorized in the Energy Act of 2020 (Division Z of the Consolidated Appropriations Act, 2021, P.L. 116-
260). The act amended the program, and in addition to the factors in the formula allocation, the Secretary of DOE also may
consider the non-energy benefits of weatherization improvements—such as improvements to health and safety—when
determining appropriate standards and procedures.
Issues for Congress center on whether to amend the current allocation procedure to account for changes in the energy
consumption of heating or cooling, to make changes to the per dwelling funding limit, to make changes to the approved
weatherization materials, or to include other factors in the formula. In the 117th Congress, several bills would make changes
to the WAP. These include increasing the authorized appropriations for the program, increasing per dwelling funding limits,
establishing a timeline for disbursement of allocated funds to states, and directing a percentage of funds to be apportioned to
environmental justice communities, among other proposals.

The Weatherization Assistance Program Formula

Introduction to the Weatherization Assistance
Program
The Weatherization Assistance Program (WAP) was established in 1976 under Title IV of the
Energy Conservation and Production Act (ECPA, P.L. 94-385, 42 U.S.C. §6861 et seq.). The
WAP enables low-income families to permanently reduce their energy consumption by making
their households more energy efficient.1 It is a formula grant program: funding flows from the
Department of Energy (DOE) to state governments (including territories, beginning in 2007) and
then to local governments and weatherization agencies. DOE program guidelines specify that a
variety of energy efficiency measures are eligible for support under the program. The measures
include insulation, space-heating equipment, energy-efficient windows, water heaters, and
efficient air conditioners.
The Energy Act of 2020 (Division Z, P.L. 116-260) amended the program and reauthorized
annual appropriations from FY2021 through FY2025. The act clarified that renewable energy
technologies and other advanced technologies are considered to be weatherization materials (42
U.S.C. §6862(9)). The act also amended section 413(b) of EPCA (42 U.S.C. §6863(b)) to
authorize DOE to account for the non-energy benefits of weatherization improvements—such as
improvements to health and safety—when determining appropriate standards and procedures for
WAP. The act added a section 414(c) of EPCA (42 U.S.C. §6864c) stating that the Secretary may
request that grant recipients review and encourage the expanded use of private contractors. A new
section 414(d) authorized the creation of a new financial assistance program for WAP
enhancement and innovation. Other changes include increasing the amount of a WAP grant that
can be used for administration purposes from 10% to 15% and changing the eligibility
requirements for reweatherization of any dwel ing to 15 years after the previous weatherization
was completed.
Currently, DOE employs a formula to al ocate WAP funding to states, the District of Columbia,
and territories (hereinafter referred to as states and territories). Each state and territory, in turn,
decides how to al ocate its share of the funding to local governments and jurisdictions.2 Funds
made available to the states are al ocated to local governments and nonprofit agencies for
purchasing and instal ing energy efficiency materials, such as insulation, and for making energy-
related repairs.3 Funds for tribes are included in a state’s formula al ocations. With a few
exceptions, funds for tribes are distributed at the state level.
This report discusses the formula that is used to al ocate WAP funds to state governments. The
formula al ocation has changed over time. The report begins with an introduction to WAP,
including the program’s statutory authority, current al ocation procedure, and origin and
evolution. Next, the report discusses the specific methods and factors for distributing WAP funds

1 T he federal WAP statute states that the primary purpose of the program is “to increase the energy efficiency of
dwellings owned or occupied by low-income persons, reduce their total residential energy expenditures, and improve
their health and safety, especially low-income persons who are particularly vulnerable such as the elderly, the
handicapped, and children.” See 42 U.S.C. §6861.
2 Administrative rules, eligibility standards, the types of aid, and benefit levels are primarily decided at the state level.
Eligibility is automatically given to applicants receiving T emporary Assistance to Needy Families or Supplemental
Security Income. Also, if a state elects, program eligibility can extended to a household that meets Low Income Home
Energy Assistance Program eligibility criteria.
3 Most of the grantees are state-designated community action agencies, which administer multiple types of social
service grants for low-income persons. No more than 10% of grant funds allocated to states may be used for
administration according to 42 U.S.C. §6865.

to the states, which involve a base al ocation and a formula al ocation. The report concludes with
a discussion of issues for Congress and identifies some related legislation introduced in the 117th
Congress.
Statutory Authority for Allocation
Under current law, DOE al ocates weatherization assistance funds to states and territories, taking
into account several factors. Section 414 of ECPA (42 U.S.C. 6864(a)) mandates that the funding
al ocation be based on “the relative need for weatherization assistance among low-income
persons.” Other factors specified in Section 414 include:
 “the number of dwel ing units to be weatherized”;
 “the climatic conditions in the state [or territory] respecting energy conservation,
which may include consideration of annual degree days”;
 “the type of weatherization work to be done in various settings”; and
 “such other factors as the Secretary [of DOE] may determine necessary, such as
the cost of heating and cooling, in order to carry out the purpose and provisions
of this part.”
DOE is required to annual y update the data used in the al ocation of funds.4
WAP’s Program Allocation
Funds for WAP are directed to several activities. DOE reserves some funds for national training
and technical assistance (T&TA) activities that benefit al states and territories. DOE al ocates
funding for T&TA activities at both the state and local levels. The total funding for national, state,
and local T&TA is limited to 10% of an annual appropriation.5
The remaining funds comprise the total al ocation to state programs. The program al ocation
consists of two parts: the base al ocation and the formula al ocation. The base al ocation for each
state is fixed, but the amount differs for each state. The fixed base was intended to prevent large
swings from previous al ocations which could disrupt a state’s program operations.
A state or territory’s program al ocation for a given year is determined using one of two methods
and is dependent upon WAP’s annual appropriation by Congress.6 If the total program al ocation
is at or above $209,724,761 (referred to as the threshold amount),7 DOE determines program
al ocations for states and territories according to a base al ocation and a formula al ocation, which
is expressed mathematical y as:
Program Allocation = Base Allocation + Formula Allocation

4 See 42 U.S.C. 6864(c).
5 T he American Recovery and Reinvestment Act of 2009 (P.L. 111-5) allowed the T &T A share to increase temporarily
to 20%.
6 T hese methods are described in an interim rule that was published and later finalized in the Federal Register in 1995.
For interim rule, see Department of Energy, “Weatherization Assistance Program for Low-Income Persons,” 60
Federal Register 29469-29481, June 5, 1995. For final rule, see Department o f Energy, “ Weatherization Assistance
Program for Low-Income Persons,” 60 Federal Register 64314-64315, December 15, 1995.
7 See 10 C.F.R. §440.10. T he threshold amount, $209,724,761, is based upon the appropriation of $226,800,000 for the
WAP in FY1995 under P.L. 103-332. After reserving funds for DOE and state and territory T &TA, total program
allocations were $209,724,761 for FY1995. The threshold amount is not adjusted for inflation.

The Weatherization Assistance Program Formula

For total program al ocations below $209,724,761, DOE determines al ocations for states and
territories according to an al ocation of $209,724,761 less the percentage decrease of the total
program al ocation from the threshold. For example, if the total program al ocation were 10%
below $209,724,761, then the program al ocation for each state or territory would be 10% less
than the program al ocation as determined for $209,724,761. Both the base al ocation and formula
al ocation would be reduced by the same proportion (10%). According to DOE, “this approach
distributes the effect of lower appropriations equitably.”8
Development of the Program Allocation Procedures
As the WAP developed, DOE changed the procedures for state al ocation of WAP funds. Two
formula al ocation procedures are discussed—those developed in 1984 and in 1995. The 1995
procedures remain in effect today. The current state al ocation consists of two parts: a fixed
amount of money derived from a state’s FY1993 al ocation as determined by WAP, and an
additional amount of money—referred to as the formula al ocation. The FY1993 al ocation was
determined according to the formula al ocation procedures developed in 1984.9
1984 Formula Allocation
In 1984, DOE developed and published standard procedures for al ocating funds within the
WAP.10 DOE divided the first $5.1 mil ion of appropriated funds equal y among the states with an
additional $100,000 al ocated to Alaska. The remaining funds available for al ocation to the states
would be dispersed according to a formula. This formula al ocation emphasized heating demand,
resulting in warmer weather states receiving less funds than colder weather states. In the formula,
the square of the number of heating degree days in a state and the square of the number of cooling
degree days in a state were each multiplied by the percentage of total residential energy used for
space heating or cooling, respectively, and then summed.11 As households typical y use more
energy for heating than cooling, this formula tended to favor states in colder climates (with more
heating degree days). In addition, DOE retained the option to reduce or increase the al ocation for
a state depending upon the likelihood of a state to expend funds.12

9 According to Department of Energy (DOE), “the proposed formula as a whole balances congressional intent of
maintaining program capacity and apportioning funds more equitably among the States. Under the formula, no State
loses more than one-half of one percent of FY1994 funds unless total program allocations fall below $220 million. All
States gain when funds rise above this amount.” DOE, “Weatherization Assistance Program for Low-Income Persons,”

11 A heating degree day (HDD) is a measurement designed to quantify the demand for energy needed to heat a building
and is typically determined as the number of degrees that a day’s average temperature is below 65o Fahrenheit. A
cooling degree day (CDD) is a measurement designed to quantify the demand for energy needed to cool a building and
is typically determined as the number of degrees that a day’s average temperature is above 65o Fahrenheit.
12 DOE stated that in determining whether funds should be reduced, “DOE will consider the amount of unexpended
financial assistance currently available to a grantee under this part and the number of dwelling units which remain to be
weatherized with the unexpended financial assistance.” For increased funds, DOE would determine the amount that
“the grantee can expend to weatherize additional dwelling units during the budget period for which financial assistance
is to be awarded.” See DOE, “Weatherization Assistance for Low-Income Persons,” 49 Federal Register 3631, January

The Weatherization Assistance Program Formula

1995 Formula Allocation
The State Energy Efficiency Program Improvement Act of 1990 (P.L. 101-440) directed DOE to
review the formula al ocation. Some were concerned that the formula favored northern states over
southern and western states. According to the Senate committee report for S. 247 (S.Rept. 101-
235), enacted as P.L. 101-440:13
The Committee intends that there be a more equitable distribution of Federal financial
assistance among the States than presently exists. The current formula’s squaring of heating
and cooling degree days does not appear to provide for an equitable national distribution
of available federal funds among low-income households. By requiring a repromulgation
of the formula, the Committee intends to achieve a more equitable distribution of such
WAP funds based on the nationwide low-income population.
In this regard, the Secretary shall determine whether, in fact, the current formula’s squaring
of heating and cooling degree days unfairly favors certain States, and, if so, shall take
immediate steps to change the allocation formula to reflect a more equitable national
distribution of funds among low-income households. In this regard, the Committee intends
that the Secretary, in consultation with the State Advisory Board established under the Act,
develop a new formula and criteria for determining the most equitable methods of
allocating weatherization funds based on low income population, number of heating and
cooling days, the relative costs of heating and cooling, and the annual costs incurred by
low-income households for heating and cooling.14
DOE undertook a rulemaking, and published the final rule in 1995.15 This formula al ocation
remains in effect.
FY2021 Allocation
DOE determines the annual funding al ocation or “total program al ocation” for weatherization
assistance for each state and territory from “the annual appropriation [by Congress] less funds
reserved for training and technical assistance.”16 For fiscal year (FY) 2021, weatherization
received $315.0 mil ion in total appropriations, of which $310.0 mil ion went to WAP and $5.0
mil ion for T&TA activities at DOE headquarters.17 Of the total appropriations, DOE was directed
to make $1 mil ion available for grant recipients that have previously worked through the
weatherization innovation pilot program (WIPP) “to implement and demonstrate programs to
treat harmful substances, including vermiculite, at the state and regional level.”18 Within available
funds, DOE reserved $18.6 mil ion to be made available via the WIPP for innovation and $6.2

mil ion to make funding available for Sustainable Energy Resources for Consumers (SERC)
Grants and al ocated an additional $0.8 mil ion for cross-cutting activities.19 Altogether, $283.4
mil ion was available to states and territories for FY2021, with $233.8 mil ion available for the
total program al ocation and nearly $49.6 mil ion for T&TA activities.20 For FY2021, the total
program al ocation was above the threshold.
Appendix A provides annual al ocation information for states, territories, and tribes for FY2001
through FY2021; the al ocations vary from year to year and reflect changes in funding levels for
the WAP and DOE al ocations for program funds and T&TA funds.
The Base Allocation
The base allocation is a fixed amount of annual funding that each state and territory receives
from appropriated sums for weatherization assistance from DOE.21 The fixed amount differs for
each state and territory and was based upon the al ocations for FY1993 as determined by DOE
according to a previous formula.22 Base al ocations, which total $171,858,000, are listed in Table
1 of 10 C.F.R. §440.10(b)(1). This table is included in Appendix B for reference.
The Formula Allocation
State and territory formula al ocations are determined from the difference between the total
program al ocation and the total base al ocation of $171,858,000. This difference can be
considered to be the total available funds for formula al ocation. For example, in FY2020, the
total available funds for formula al ocation was $77,374,500 (the difference between the FY2020
total program al ocation—$249,232,500—and the base al ocation—$171,858,000). The formula
allocation for each state or territory is determined by multiplying the total available funds for
formula al ocation by a state or territory’s formula share. The state formula al ocation is
expressed mathematical y as:
State Formula Allocation = Total Funds for Formula Allocation × State Formula Share
The formula share is the product of three factors—population, climate, and residential energy
expenditures—normalized by the national total of the product of each state’s three factors.

19 Section 411 of the Energy Independence and Security Act of 2007 (EISA 2007, P.L. 110-140) stipulates that WAP
funds may be used to award Sustainable Energy Resources for Consumers (SERC) grants only when WAP funding for
a given fiscal year is at or above $275 million . EISA 2007 also directs DOE to limit SERC grant funding to 2% of
WAP funds; therefore for FY2021, SERC funds are limited to no more than $6.2 million (or 2% of $310 mil lion). In
addition, DOE also allocated $825,000 in FY2021 WAP funds for cross-cutting activities. DOE, “ Program Year 2021

20 DOE reserved nearly $52.9 million for T &TA activities for states and territories, which is less than the 20% that
DOE may reserve for grantees per 42 U.S.C. §6866. See DOE, “ Program Year 2020 Grantee Allocations,”

21 See 10 C.F.R. §440.10(b)(1).
22 In 1995, DOE issued an interim rule (which was later finalized) that established an updated allocation formula “to
provide warmer-weather States a greater share of the funding, while protecting the Program capacity developed over
the years by colder-weather States.” See Department of Energy, “ Weatherization Assistance Program for Low-Income
Persons,” 60 Federal Register 29470, June 5, 1995.

The Weatherization Assistance Program Formula

Factor 1: Population
The population factor (Factor 1) is the percentage of the U.S. low-income households in each
state or territory. The formula gives equal weight to owners and renters. The American Recovery
and Reinvestment Act of 2009 (ARRA, P.L. 111-5 §407a) revised the program guidelines to raise
the low-income eligibility ceiling from 150% to 200% of the poverty level.23
The U.S. Energy Information Administration’s (EIA’s) 2009 Residential Energy Consumption
Survey (RECS) estimated that there were 113.6 mil ion households in the United States.24 Of the
113.6 mil ion households, approximately 39.5 mil ion households (or nearly 35%) were federal y
eligible for weatherization assistance. The distribution of low-income households in the United
States in 2009 was “in roughly the same proportions as the non-low-income population, with
approximately 16% in the Northeast, 23% in the Midwest, 41% in the South, and 20% in the
West.”25 EIA’s 2015 RECS—with the most recent survey data—estimated that the total number
of households has increased in the United States to 118.2 mil ion.26 Although CRS did not
identify a source for the number of households that were eligible for weatherization assistance in
2015, EIA’s 2015 RECS did estimate that 37.0 mil ion of the 118.2 mil ion households in the
United States experienced energy insecurity.27
Factor 2: Climate
The climate factor (Factor 2) accounts for the variation in climatic conditions that can affect
household energy consumption (i.e., energy demand for heating and cooling). The factor accounts
for the energy needed for heating and cooling in a proportional manner. The factor relies upon 30-
year averages of heating degree days and cooling degree days as reported by the National
Oceanic and Atmospheric Administration (NOAA). According to NOAA, the 30-year averages
are updated once every 10 years.28 In May 2021, NOAA published 30-year climate normals for
the period from 1991 through 2020.29 A heating degree day (HDD) is a measurement designed to
quantify the demand for energy needed to heat a building and is typical y determined as the
number of degrees that a day’s average temperature is below 65o Fahrenheit. A cooling degree

23 At the time of the 1995 rulemaking for the formula allocation, the low-income eligibility ceiling was 125% of the
poverty level. T he number of low-income households used in the rulemaking was obtained from a special tabulation of
Census data completed by the Bureau of the Census for the Department of Energy .
24 Of the 113.6 million households, EIA reported that 16.9 million households were below the poverty line in 2009.

The Weatherization Assistance Program Formula

day (CDD) is a measurement designed to quantify the demand for energy needed to cool a
building and is typical y determined as the number of degrees that a day’s average temperature is
above 65o Fahrenheit. Factor 2 is the sum of the HDD ratio (a state HDD divided by the national
median HDD) and the CDD ratio (a state CDD divided by the national median CDD multiplied
by 0.1) for each state or territory, treating the energy needed for heating and cooling in a
proportional manner. Mathematical y, Factor 2 is expressed as:
State HDD
State CDD
Factor 2=
+ (
× 0.1)
National Median HDD
National Median CDD
Including 0.1 in the CDD ratio—according to the 1995 interim rule—accounted for the difference
in national energy consumption data between heating and cooling. According to 1990 data from
EIA, national heating consumption equaled 4.79 quadril ion Btu while air conditioning
consumption equaled 0.49 quadril ion Btu.30 At the time, heating consumed approximately 10
times more energy than air conditioning; however, according to the 2015 RECS, EIA estimates
national heating energy consumption has declined to 3.95 quadril ion Btu while national air
conditioning energy consumption has increased to 0.73 quadril ion Btu.31 Using the data within
the 2015 RECS, heating consumes approximately 5.4 times more energy than air conditioning.
Factor 3: Residential Energy Expenditure
The residential energy expenditure factor (Factor 3) is an estimate of the residential energy
expenditure (REE) for low-income households for a state or territory. Energy expenditures for
low-income households are not available at the state level. Further, EIA provides data for state
residential energy consumption including expenditure data, but EIA does not distinguish between
low-income households and other households. Therefore the factor is determined based on
publicly available data from the U.S. Census Bureau. At the Census division level, residential
energy expenditure data is available for the overal population and for low-income households
(referred to as “Division REE”).32 According to the 1995 interim rule, “the underlying assumption
in the calculation of State residential energy expenditures per low-income household is that the
relationship between a State’s residential energy expenditures per household and its respective
divisional residential energy expenditures per household is the same for its low-income
population as it is for its general population.”33 For example, if an average household in a state
spends 50% more on residential energy than the average household in its Census division, then it
is assumed that low-income households in the same state would also spend 50% more on
residential energy than the average low-income household in its Census division. To determine

Potential Issues for Congress
Under the current procedure, the method of funding al ocation is dependent upon whether WAP’s
annual appropriation is at or exceeds a monetary threshold, as discussed. An issue for Congress is
whether to maintain this approach and continue to direct the al ocation procedure through annual
appropriations. Alternatively, Congress could amend the authorizing language to address concerns
regarding the current al ocation procedure. They center on whether adjustments are needed to
account for changes in heating and cooling or to include other factors in the formula. Another
issue is sufficiency of appropriations for the program.
Congress could direct DOE to examine the current al ocation formula and determine whether
revisions to the current approach should be undertaken. Congress previously directed DOE to
revise the weatherization al ocation formula “in order to al ow for a more equitable
apportionment of funds while not harming the existing capacity of any State to weatherize
homes.”34 The DOE examination resulted in the 1995 rulemaking and current al ocation formula.
Congress may consider whether adjustments to the formula are merited to account for changes in
heating and cooling. As discussed in “Factor 2: Climate,” the energy consumption ratio of heating
to air conditioning has declined from approximately 10 to 5.4. Factor 2 also relies upon 30-year
averages of HDDs and CDDs as reported and updated by NOAA on a 10-year basis. As the U.S.
average annual temperature has increased, heating degree days have decreased and cooling
degree days have increased overal .35 The exception to this are states within the Southeast
(excluding Florida), which have seen more HDDs and fewer CDDs.36 Long-term averages may
not reflect present or future conditions or sufficiently capture the potential energy expenditure
burden associated with heating and cooling during extreme temperatures. According to the Fourth
National Climate Assessment (NCA4), extreme temperatures are projected to increase even more
than average temperatures in the contiguous United States.37 The EIA projects that delivered
energy for air conditioning of buildings wil increase in the building sector through 2050 while
energy for space heating wil decline during the same period.38 In addition, the HDD or CDD

34 In H.Rept. 103-740, the Conference Report on the Department of Interior and Related Agencies Appropriations Act,
1995, P.L. 103-332, the conference committee stated that sufficient funds would be made available to permit DOE to
revise the weatherization allocation formula “ in order to allow for a more equitable apportionment of funds while not
harming the existing capacity of any State to weatherize homes.”

The Weatherization Assistance Program Formula

determined for a state may not capture the actual HDD and CDD experienced in urban areas.
Studies have shown evidence of heat islands in urban areas and that persons of color and low-
income households within some urban areas experience additional elevated heat exposure.39
In addition to altering the existing factors within the WAP’s formula al ocation, Congress may
include other factors. In the 117th Congress, several bil s would make changes to the WAP. Some
bil s would increase authorization of appropriations for the program.40 Some proposals would
increase per dwel ing funding limits.41 One proposal would establish a timeline for DOE to
disperse al ocated funds to states.42 Another bil would direct a percentage of fees received into
the Treasury to be appropriated to the weatherization assistance program and apportioned to
environmental justice communities.43
Changing the amount of appropriations or the formula al ocation may have different outcomes.
Increasing appropriations to the WAP under the existing program al ocation would provide
additional funding to al states and territories. Changing the formula al ocation to reflect changes
in energy consumption due to heating and cooling and changes in HDDs and CDDs—holding al
other factors constant—may increase formula al ocations to states and territories in warmer
climates (or those areas where a greater percentage of a household’s energy consumption is due to
air conditioning). Expanding the factors that DOE should consider—such as the health and safety
of occupants—may introduce other changes to formula al ocations and the subsequent program
al ocations to states and territories.

39 T he term “heat island” describes urban areas that have hotter surface and air temperatures than nearby rural areas.
T he urban heat island can affect communities by increasing energy demand and energy costs for cooling and air
conditioning, air pollution and greenhouse gas emissions, heat -related illness and mortality, and water pollution. See

Source: Department of Energy (DOE) annual Weatherization Program Notices regarding Grantee Al ocations, accessed from the Weatherization Program Guidance
documents library at the National Association for State Community Services Programs (NASCSP). Documents were previously housed on the former Weatherization
Assistance Program Technical Assistance Center (WAPTAC) website. WAPTAC’s resources and documents library has since been incorporated into the NASCSP
website.
Notes: Each state al ocation is the sum of the state program al ocation and the state training and technical assistance al ocation. The Energy Independence and Security
Act of 2007 (P.L. 110-140, §411c) added Puerto Rico and other territories of the U.S. to the definition of “State” for the purpose of funding al ocations. Beginning with
Program Year 2009, the territories of American Samoa, Guam, Commonwealth of the Northern Mariana Islands, Commonwealth of Puerto Rico and the U.S. Virgin
Islands were added to the program. Tribal Government Al ocations are derived from state al ocations: Navaho Grant al ocations are from Arizona and New Mexico state
al ocations; Inter-Tribal Council of Arizona Grant al ocations are from Arizona al ocations; and Northern Arapahoe Grant are from Wyoming al ocations.

Source: Department of Energy (DOE) annual Weatherization Program Notices regarding Grantee Al ocations, accessed from the Weatherizat ion Program Guidance
documents library at the National Association for State Community Services Programs (NASCSP). Documents were previously housed on the former Weatherization
Assistance Program Technical Assistance Center (WAPTAC) website. WAPTAC’s resources and documents library has since been incorporated into the NASCSP
website.
Notes: Each state al ocation is the sum of the state program al ocation and the state training and technical assistance al ocation. The Energ y Independence and Security
Act of 2007 (P.L. 110-140, §411c) added Puerto Rico and other territories of the U.S. to the definition of “State” for the purpose of funding al ocations. Beginning with
Fiscal Year 2009, the territories of American Samoa, Guam, Commonwealth of the Northern Mariana Islands, Commonwealth of Puerto Rico and the U.S. Virgin Islands
were added to the program. Tribal Government Al ocations are derived from state al ocations: Navaho Grant al ocations are from Arizona and New Mexico state
al ocations; Inter-Tribal Council of Arizona Grant al ocations are from Arizona al ocations; and Northern Arapahoe Grant al ocations are from Wyoming al ocations.
Also, P.L. 111-5 was enacted as the American Recovery and Reinvestment Act of 2009. It is referred to in the last column by the shorthand “ARRA.”
