	Overview

During the Vietnam War, the U.S. military conducted Operation Ranch Hand, a program that sprayed an estimated 18-20 million gallons of herbicides—including approximately 11-12 million gallons of Agent Orange —over about 12,000 square miles of southern Vietnam between 1961 and 1971. A contaminant of the manufacture of Agent Orange (as well as two other herbicides used, Agent Pink and Agent Purple) was 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), a developmental toxicant and a probable human carcinogen according to the U.S. Environmental Protection Agency.
Environmental surveys conducted in Vietnam have identified a number of dioxin "hot spots," including the airbases at Bien Hoa, Danang, and Phu Cat, that are contaminated with TCDD well above internationally acceptable levels (see Figure 1 ). In addition, the A Luoi (or A Shau) Valley, south of Quang Tri and west of Danang, was considered an important segment of the Ho Chi Minh Trail, a key supply route used by North Vietnamese forces and their allies, and was therefore heavily sprayed. The former U.S. military base in the A Luoi Valley has been identified as another "hot spot."
In recent years, U.S. response to the environmental damage and health problems caused by Agent Orange and its associated dioxin in Vietnam has been viewed as helping to advance bilateral relations between the two nations. After a meeting with President Tran Dai Quang in May 2016, President Obama stated the following:
With regard to security, the United States will continue to do our part to address the painful legacy of war.... We'll continue to help remove unexploded landmines and bombs. And now that our joint effort to remove dioxin—Agent Orange—from Danang Airport is nearly complete, the United States will help in the cleanup at Bien Hoa Air Base.
The joint statement issued after that meeting included the following statements:
Vietnam welcomed cooperation leading to the successful conclusion of the first phase of dioxin remediation at Danang International Airport, with the final phase underway. The United States committed to partnering with Vietnam to make a significant contribution to the clean-up of dioxin contamination at Bien Hoa Air Base.
The Trump Administration has continued the past commitment to provide assistance to Vietnam to address the Agent Orange/dioxin issue. Following their meeting in May 2017 in Washington, DC, President Trump and Prime Minister Nguyen Xuan Phuc released a joint statement, which stated:
The two sides committed to work together to address war legacy issues, including through such joint efforts as dioxin remediation, taking note of the progress that has been made at Da Nang Airport and intent to discuss continued collaboration at Bien Hoa Airport, and the removal of unexploded ordnances.
On November 10, 2017, Under Secretary of State Thomas Shannon and Senior Lieutenant General Nguyen Phuong Nam held a ceremony to celebrate the completion of the environmental remediation of Danang Airport. On January 23, 2018, the two governments signed a Memorandum of Intent (MOI) to begin the process of dioxin decontamination of Bien Hoa.
From 2007 to the present, Congress has appropriated a total of $254.8 million for the environmental remediation of Agent Orange/dioxin and health and disability programs in areas of Vietnam sprayed with Agent Orange or otherwise contaminated by dioxin. Starting with the 112 th Congress, the legislation has appropriated separate amounts for these two purposes, generally with more funds appropriated for environmental remediation than for health and disability programs. All of the amounts appropriated by Congress are subject to the provisions of Section 653(a) (22 U.S.C. §2413(a)) of the Foreign Assistance Act of 1961, as amended (P.L. 87-195; 22 U.S.C. §2151 et seq.). As a consequence, the actual amount available for such assistance may be less than the amount specified in the various laws and their accompanying reports.
In addition, the 115 th Congress, under Section 1052 of the John S. McCain National Defense Authorization Act for Fiscal Year 2019 ( P.L. 115-232 ), authorized the Secretary of Defense to transfer "not more than $15,000,000" in FY2019 to the Secretary of State, for use by USAID, "to be used for the Bien Hoa dioxin cleanup in Vietnam." Any funds transferred are to be taken from the Department of Defense's "Operation and Maintenance, Defense-wide" account.
The appropriated funds for environmental remediation generally have been allocated under the State Department's Economic Support Fund account (ESF), while the funds for health and disability programs have been allocated under the Development Assistance account (DA). In general, the funds appropriated under both accounts have been made available for two fiscal years. The State Department has delegated responsibility for the administration and obligation of the appropriated funds to the U.S. Agency for International Development (USAID).
To date, most of the environmental remediation effort has been focused on the cleanup of the Danang airport, while the funds appropriated for health and disability programs have been used primarily for disability support programs in Danang and other parts of Vietnam. The cleanup of Danang airport has been completed, and U.S. and Vietnamese officials have made arrangements for joint dioxin removal operations at the airbase in Bien Hoa. In addition, the two governments are discussing the appropriate manner to address health and disability problems among Vietnamese nationals that may be attributable to dioxin exposure.
The programs and projects funded by the appropriated funds have been administered by the State Department and USAID, in cooperation with various ministries and agencies within the Vietnamese government. In 1999, Vietnam's central government created the Office of the National Steering Committee on Overcoming Consequences of Agent Orange/Dioxin in Vietnam (Office 33, or Committee 33), an interministerial body, to oversee and coordinate its government's policy on Agent Orange and dioxin. Office 33 includes representatives from Vietnam's Ministry of Natural Resources and Environment (MONRE, where Office 33 is administratively located); Ministry of Finance (MOF); Ministry of Foreign Affairs (MOFA); Ministry of Health (MOH); Ministry of Labour, Invalids, and Social Affairs (MOLISA); Ministry of National Defence (MND); Ministry of Planning and Investment (MOPI); and Vietnam Academy of Science and Technology (VAST).
Congressional interest has generally focused on two issues. The first issue is determining the amount to allocate for the environmental remediation of dioxin "hot spots" in Vietnam and health and disability programs in areas of Vietnam sprayed with Agent Orange or otherwise contaminated by dioxin. The second issue is oversight to ascertain if the State Department and USAID are effectively and appropriately obligating and expending the available funds. In particular, Congress has paid attention to the rate at which USAID has obligated the funds Congress appropriated for use on health and disability activities.

	Congressional Appropriations Since 2007

The appropriation of funds explicitly to address the Agent Orange/dioxin issue in Vietnam started in May 2007, when the 110 th Congress passed the U.S. Troop Readiness, Veterans' Care, Katrina Recovery, and Iraq Accountability Appropriations Act, 2007 ( P.L. 110-28 ). That act appropriated $3 million "for the remediation of dioxin contaminated sites in Vietnam, and to support health programs in communities near those sites." After more than a year of internal consultation, the State Department decided that the administration and obligation of the $3 million would be handled by USAID, setting a precedent for the handling of future appropriations for Agent Orange/dioxin assistance to Vietnam.
The 111 th Congress in three separate pieces of legislation appropriated a total of $18 million for dioxin cleanup in Vietnam and related health services (see Table 1 ). In March 2009, the 111 th Congress appropriated $3 million for Agent Orange/dioxin remediation and health care assistance in the vicinity of the Danang "hot spot" in the Omnibus Appropriations Act, 2009 ( P.L. 111-8 ). In December 2009, Congress passed the Consolidated Appropriations Act, 2010 ( P.L. 111-117 ), which included $3 million for dioxin cleanup and related health services in Vietnam. In July 2010, Congress included $12 million "to support the remediation of dioxin contamination at the Danang Airport, which poses extreme risks to human health and welfare, and related health activities" in the Supplemental Appropriations Act, 2010 ( P.L. 111-212 ). In addition, the State Department and USAID allocated $1.9 million in Development Assistance funds for FY2010 for environmental remediation at Danang airport.
The conference report accompanying P.L. 112-74 also endorsed language in a Senate report associated with an earlier reported to Senate version of the Department of State, Foreign Operations, and Related Programs Appropriations Act, 2012 ( S. 1601 ) directing USAID, in consultation with the Senate Appropriations Committee, the Department of State, the Government of Vietnam, and "other interested parties," to develop a "comprehensive, multiyear plan" for Agent Orange-related activities in Vietnam within 180 days after the enactment of the law.
The 113 th Congress continued to appropriate funds for the environmental remediation of Agent Orange/dioxin in Vietnam and related health services. The Consolidated and Further Continuing Appropriations Act, 2013 ( P.L. 113-6 ), which superseded P.L. 112-175 , renewed the appropriation levels contained in P.L. 112-74 for FY2013, subject to sequestration requirements. Similarly, P.L. 113-46 and P.L. 113-73 renewed appropriations for FY2014 until being superseded by the Consolidated Appropriations Act, 2014 ( P.L. 113-76 ), which appropriated $22.0 million for environmental remediation and $7.0 million for "health and disability programs in areas sprayed with Agent Orange or otherwise contaminated by dioxin." Section 7043(h) of the Consolidated and Further Continuing Appropriations Act, 2015 ( P.L. 113-235 ) states the following:
Funds appropriated by this Act under the heading "Economic Support Fund" shall be made available for remediation of dioxin contaminated sites in Vietnam and may be made available for assistance for the Government of Vietnam, including the military, for such purposes, and funds appropriated under the heading "Development Assistance" shall be made available for health/disability activities in areas sprayed with Agent Orange or otherwise contaminated with dioxin.
The act's accompanying "Explanatory Statement" specifies that $7.5 million is to be provided under "Development Assistance" for "Vietnam health/disability programs" and $15.0 million is to be provided under "Economic Support Fund" for "Vietnam (Environmental remediation of dioxin)."
In Section 7043(g) of P.L. 114-113 , the 114 th Congress appropriated funds under the Economic Support Fund for "remediation of dioxin contaminated sites in Vietnam" and under Development Assistance for "health and disability programs in areas sprayed with Agent Orange and otherwise contaminated with dioxin, to assist individuals with severe upper or lower body mobility impairment and/or cognitive or developmental disabilities." S.Rept. 114-79 , which accompanied P.L. 114-113 , provided "not less than $25 million" for environmental remediation and $7 million for "health/disability programs in areas sprayed with Agent Orange or otherwise contaminated by dioxin, to address the mobility, psycho-social, vocational, and other needs of persons with severe upper and lower body mobility impairment and/or cognitive or developmental disabilities." The report continued with the statement, "In order to minimize administrative costs and maximize impact in the field, the Committee intends that, to the maximum extent practicable, health/disability funds shall be implemented by Vietnamese organizations and entities."
Funding for FY2017 was included in the Consolidated Appropriations Act, 2017 ( P.L. 115-31 ). Section 7043(h) states:
(1) DIOXIN REMEDIATION—Notwithstanding any other provision of law, of the funds appropriated by this Act under the heading `Economic Support Fund', not less than $20,000,000 shall be made available for activities related to the remediation of dioxin contaminated sites in Vietnam and may be made available for assistance for the Government of Vietnam, including the military, for such purposes.
(2) HEALTH AND DISABILITY PROGRAMS—Of the funds appropriated by this Act under the heading 'Development Assistance', not less than $10,000,000 shall be made available for health and disability programs in areas sprayed with Agent Orange and otherwise contaminated with dioxin, to assist individuals with severe upper or lower body mobility impairment and/or cognitive or developmental disabilities.
The act permits, for the first time since the United States has funded dioxin environmental remediation in Vietnam, the provision of assistance to the Government of Vietnam. It also reiterates that health and disability programs are to be in areas sprayed with Agent Orange or otherwise contaminated with dioxin.
In March 2018, the 115 th Congress appropriated in the Consolidated Appropriations Act, 2018 ( P.L. 115-141 ) "not less than $20 million" for "activities related to the remediation of dioxin contaminated sites in Vietnam." The act also provided that the funds "may be made available for assistance for the Government of Vietnam, including the military, for such purposes." In addition, the act appropriated "not less than $10 million" for "health and disability programs in areas sprayed with Agent Orange and otherwise contaminated with dioxin, to assist individuals with severe upper or lower body mobility impairment or cognitive or developmental disabilities."
In February 2019, 116 th Congress appropriated in the Consolidated Appropriations Act, 2019 ( P.L. 116-6 ) "not less than $20,000,000" for "activities related to the remediation of dioxin contaminated sites in Vietnam and may be made available for assistance for the Government of Vietnam, including the military, for such purposes." The Act also appropriated "not less than $12,500,000 … for health and disability programs in areas sprayed with Agent Orange and otherwise contaminated with dioxin, to assist individuals with severe upper or lower body mobility impairment or cognitive or developmental disabilities."

	USAID Obligations

The State Department has designated USAID as the responsible agency for the obligation of the appropriated funds for Agent Orange/dioxin-related activities in Vietnam . Table 2 lists the amounts USAID has obligated of funds appropriated over FY2007 to FY2017 by type of activity, implementing partner, and fiscal year. As of May 2018, USAID has obligated 81% of the $127 million appropriated for FY2011-FY2017 for environmental remediation projects, and 63.5% of the $44.3 million appropriated for FY2011-FY2017 for health- and disability-related services. Of the $21 million appropriated for FY2007-FY2011 for either environmental remediation or health- and disability-related services, USAID has obligated $20.3 million, or 96.9%.
The manner in which USAID has obligated the appropriated funds has, at times, been an issue with Congress. While the rate of obligations for environmental remediation activities generally has not been a matter of concern, how USAID has obligated appropriations for health and disability activities has drawn some congressional attention. The two main concerns about the health and disability obligations are the seemingly slower pace of utilization (when compared to the environmental remediation funds), and the types of programs being funded.
Since Congress began appropriating funds specifically for Agent Orange/dioxin-related activities in Vietnam in FY2007, it generally has designated that the health and disability services are to be provided in locations near Agent Orange/dioxin-contaminated areas. The $3 million appropriated in FY2007 in P.L. 110-28 was "to support health programs in communities near those sites," according to the accompanying Senate report. The joint committee print accompanying P.L. 111-8 stipulated that "$3,000,000 is provided to continue environmental remediation of dioxin contamination at the Danang Airport and related health activities in nearby communities in Vietnam." H.Rept. 112-331 , which accompanied P.L. 112-74 , stated, "The conferees recommend not less than $5,000,000 under this heading be made available for health/disability activities in areas in Vietnam that were targeted with Agent Orange or remain contaminated with dioxin." It is unclear if the State Department and USAID have in all cases obligated these funds in accordance with this locational guidance.
Based on the information provided by USAID, funds for health- and disability-related services in FY2007-FY2009 were obligated to programs in Danang. However, for FY2010 to FY2013, the appropriated health and disability funds were largely obligated to Development Alternatives, Inc. (DAI) for a disability support program that was designed to "broadly address the needs and improve the lives of persons with disabilities," without explicit reference to Agent Orange/dioxin "hot spots." According to USAID, this three-year program ended in January 2016.
Following consultations with the Ministry of Labour, Invalids, and Social Affairs (MOLISA), Congress, and other interested parties, as of FY2014, USAID reportedly returned to directly obligating funds for health- and disability-related services in smaller amounts and increased its outreach to Vietnamese nongovernmental organizations. This shift to smaller direct program funding is reflected in Table 1 . For more about USAID's disability programs in Vietnam, see " Disability Programs " below.

	Danang Airport Environmental Remediation Project

One of the main activities financed by congressional appropriations related to Agent Orange/dioxin in Vietnam is the environmental remediation project at Danang Airport. Since its beginnings in 2008, when the U.S. and Vietnamese governments started plans for the environmental remediation of Danang airport, the project has experienced delays in implementation, unexpected increases in the amount of material requiring decontamination, and rising costs. While USAID's initial intent was to complete the project by October 2013, a November 2014 U.S. government audit indicated that the estimated completion date for the project was March 31, 2017. The decontamination was completed in August 2017. During the life of the project, the amount of material to be decontaminated rose from an estimated 61,700 cubic meters (m 3 ) to approximately 90,000 m 3 , plus an additional 60,000 m 3 of "lower risk material." The estimated cost of the project increased from $33.7 million to over $110 million.
The joint military/civilian airport in Danang was a major operational hub for the U.S. military's Operation Ranch Hand. One study of Danang airbase found soil concentrations of "TCDD toxic equivalents" (TEQ) of up to 365 parts per billion (ppb)—365 times the international maximum level of 1.0 ppb . Seventeen out of the 23 soil samples taken at Danang airbase exceeded the international maximum standard.
Work on the project began in December 2009, when the State Department and Vietnam's Ministry of Natural Resources and the Environment (MONRE) signed a memorandum of understanding (MOU) setting the framework for implementing environmental health and remediation programs in Danang. The MOU designated USAID and Office 33 as the implementing agencies. According to a State Department press release, the MOU covered $6.0 million in funds appropriated in FY2007 and FY2009. Among the activities included in the MOU was a grant to CDM International, Inc., in association with Hatfield Associates, to design an environmentally sound engineering approach to dioxin containment at Danang airport.
In June 2010, USAID completed an Environmental Assessment (EA) of Danang airport that recommended the use of thermal desorption to decontaminate an estimated 61,700 m 3 of contaminated material in six separate "hotspots" at the airport. The EA estimated that the decontamination would take two years to complete at a cost of $33.7 million, but noted that implementation would present "challenges" that could increase the cost by 50%.
USAID and Vietnam's Ministry of National Defence (MND) signed a Memorandum of Intent in Hanoi on December 30, 2010, with the goal of starting the remediation project in the summer of 2011 and completing the project by October 2013. The Prime Minister approved the remediation of Danang airport by in-pile thermal desorption (IPTD) in February 2011, and MND approved the project in April 2011.
USAID posted a Request for Proposals (RFP #486-11-028) in May 2011 for bids on the project. In July 2012, USAID awarded two contracts for the environmental remediation of Danang airport by IPTD. CDM Smith, a U.S. firm headquartered in Massachusetts, was granted $8.37 million for project oversight and construction management. Tetra Tech, Inc., headquartered in California, was awarded $17 million for the excavation and construction components of the project. A ceremony to launch the Danang airport environmental remediation project was held at Danang airport on August 9, 2012; onsite work began on August 20, 2012.
An internal USAID audit of the remediation project conducted in November 2014 indicated that six contracts have been awarded for the environmental assessment and remediation project at Danang airport, plus an assessment of Bien Hoa airbase (see Table 3 ). Three of the awarded contracts correspond to the amounts provided by USAID in Table 2 , but three do not, probably reflecting work beyond FY2013.
The thermal desorption of the contaminated soil was done in two phases, due to the amount of material involved. The gradual heating of Phase 1, which involved the treatment of approximately 45,000 m 3 of soil contained in an area 70 meters wide and 100 meters long (about the size of a football field) and 8 meters (26 feet) high, began in April 2014. The cooling down of Phase 1 started in April 2015, after soil sampling revealed that more than 95% of the dioxin had been removed. Excavation for Phase 2, which involved the draining of three small lakes and the removal of the exposed lake beds, began in January 2015. The treatment of 45,000 m 3 of Phase 2 soil began in November 2016, and was completed in August 2017.
Progress on the decontamination of Danang airport was delayed by several factors. Weather during Vietnam's rainy season (September to December) hampered progress on the excavation of soil and the construction of the thermal treatment area. Soil testing following the drainage of the small lakes determined more soil and sediment would require decontamination than previously estimated. The secondary treatment facility was shut down in July 2014 to change the filtering system. It also took more time than anticipated to raise the ambient temperature of the Phase 1 soil to the target 335°C.
USAID's Office of Inspector General conducted an internal audit of the environmental remediation project in November 2014, and noted several potential risks that could delay the project and, by extension, raise its overall cost, including the problems associated with inclement weather and cooling the treated soil. The audit particularly noted the lack of a formal risk management plan to address some of the project risks identified by USAID and the project's contractors, and recommended that a formal risk management plan be implemented. The audit also cited CDM for providing inaccurate performance data and not fulfilling its obligations to provide training to Vietnamese officials, and recommended that more training be provided and better data documentation procedures be adopted. USAID agreed with all of the audit's recommendations.
On November 7, 2018, the two governments held a ceremony to mark the completion of the Danang Airport environmental remediation project. The completed project took more than twice as long and cost more than three times as much as initially projected by USAID. According to Pham Quang Vu, head of Vietnam's Air Force and Air Defense Military Science Division, the higher cost and greater time was due to underestimating the contamination at the airport, indicating that 162,500 cubic meters of soil—not 72,900 cubic meters—were contaminated. Anthony Kolb, chief of USAID's environmental remediation unit, stated that the dioxin had percolated three meters deeper than expected.

	Disability Programs

USAID has, in general, utilized the funds Congress appropriated for health/disability activities in areas sprayed with Agent Orange or otherwise contaminated with dioxin as part of its overall program to provide support for persons with disabilities in Vietnam, regardless of the cause of the disability or proximity to Agent Orange "hot spots." According to USAID, starting in 1989 with a program financed by the Leahy War Victims Fund, the U.S. government has provided over $60 million in assistance to disabled Vietnamese, regardless of the cause of the disability. This assistance includes funds specifically appropriated for health services in areas located near Agent Orange/dioxin-contaminated sites and other sources of developmental or health assistance.
Between FY2007 and FY2010, the State Department and USAID utilized the funds appropriated for health services for grants to various agencies to offer programs to improve the quality of life for persons with disabilities in Danang. A December 2010 USAID assessment of these grants noted the "many accomplishments" of these programs, but also noted that the three-year time period was "very short for meeting program objectives."
In 2012, USAID approved a three-year, nationwide Persons with Disability Support Program (PDSP) to be jointly implemented with Development Alternatives, Inc. (DAI) and Vietnam Assistance for the Handicapped (VNAH). The request for applications (RFA) for the project indicated that the program was intended to "build on the accomplishments of the previous USAID assistance to people with disabilities (PWD) living in communities in Danang, as well as include additional relevant public health activities." The project's geographic focus was to be primarily in Danang, and "to some extent other areas, proposed by the Recipient, where there is a high disability burden, the need is the greatest, and in regions where dioxin hot spots are located." The RFA specifically calls for a needs assessment to be conducted in Bien Hoa and Phu Cat. Funding for PDSP was initially set at $9 million.
As part of PDSP's cooperative agreement, DAI was to award grants to local partners and organizations providing assistance to persons with disabilities, including health services, rehabilitation therapy, vocational training, and community awareness. In addition, USAID provided assistance to VNAH to work on disability policy and legal framework needs of the Government of Vietnam.
The PDSP program was headquartered in Danang, and initially operated in the provinces of Binh Dinh, Danang, and Dong Nai—where the three dioxin "hot spots" of Phu Cat, Danang, and Bien Hoa (respectively) are located. According to a June 2015 USAID update, the PDSP program has been extended to the provinces of Quang Nam, Tay Ninh, and Thua Thien-Hue. According to the Aspen Institute, all three provinces were heavily sprayed with Agent Orange during the Vietnam War, but have not been identified as "hot spots." A USAID summary of the program after two years reported that "nearly US$900,000 in grants to 14 local partners and organizations" had been awarded.
In June 2014, USAID adopted a new approach to the provision of assistance to persons with disabilities in Vietnam. According to the USAID statement, one of the key objectives of USAID assistance to Vietnam is to foster expanded opportunities to vulnerable populations, such as persons with disabilities. To that end, USAID aims "to address key challenges for persons with disabilities through provision of direct assistance to improve health, independence, and participation in economic and social life."
In addition to continuing to support changes in Vietnam's disability policies, USAID will finance the provision of physical, occupational, and speech therapies to persons with disabilities, as well as provide training to Vietnamese practitioners and technicians in the delivery of such services. Target areas for these programs are to be locations "where disability prevalence and poverty rates are high." Among the identified locations are the provinces of Binh Dinh, Binh Phuoc, Dong Nai, Quang Nam, Tay Ninh, Thai Binh, and Thua Thien-Hue. All these provinces have been identified by the Aspen Institute as heavily sprayed areas, except Thai Binh. USAID, in consultation with various Vietnamese agencies, will directly administer the new approach.

	Bien Hoa Airbase

With the environmental cleanup of Danang airport completed, the two governments have begun jointly to explore undertaking a similar cleanup of the dioxin "hot spot" located at the Bien Hoa airbase. Bien Hoa airbase was the airport used for the most Agent Orange spraying missions during the war, and is where the most herbicide was stored and used by the U.S. military. One study of soil samples from the Bien Hoa airbase found a sample with a TEQ concentration at over 1,000 ppb—higher than typical samples at the Danang airbase, and 1,000 times higher than the international limit.
The Vietnamese government has already conducted some mitigation measures to contain the dioxin contamination at Bien Hoa. A passive landfill (in which the contaminated soil is left untreated) containing 43,000 m 3 of contaminated soil excavated from the herbicide storage area was completed in 2009. However, the airbase has several other distinct dioxin "hot spots" that have not been addressed, according to a study conducted by a private consulting firm, Hatfield Consultants, hired by Office 33. The study also determined that contaminated soil had spread from the "hot spots" into nearby lakes, ponds, creeks, and drainage ditches, increasing the amount of soil and sediment that will require treatment.
The United Nations Development Programme (UNDP) has been working with Office 33 and MONRE for five years to map out the dioxin contamination at Bien Hoa airbase, and develop a master plan for dioxin remediation. According to their joint investigation, released in 2014, approximately 250,000 m 3 of soil would require decontamination with an estimated cost of at least $250 million.
In September 2013, USAID contracted CDM International Inc. to conduct an environmental assessment of the Bien Hoa airbase to examine a number of dioxin remediation alternatives. CDM International Inc. partnered with Hatfield Consulting on the project. In May 2016, USAID released the final environmental assessment report.
The report determined that an estimated 408,500 to 495,300 m 3 of contaminated soils and sediments are located on or nearby the airbase, or about four to five times as much as is being treated at Danang airport. Five different treatment methods were considered, ranging from containment to in-pile thermal desorption (as was used in Danang). The estimated costs of the five methods ranged from $137 million (for containment in a landfill) to $794 million (using incineration and ex situ thermal treatment). The report noted, however, that these estimated costs may vary from 40% less to 75% more than the stated amounts, expanding the possible range to between $82 million and $1.4 billion. According to USAID, over $3.7 million has been obligated so far to assess the possible environmental remediation of Bien Hoa Airbase.
In September 2017, Vietnam's Ministry of National Defence announced work on infrastructure construction for the dioxin decontamination of Bien Hoa airport. The construction, with a reported budget of $11.8 million, included demining operations, road construction, and removing facilities from contaminated areas.
On January 23, 2018, USAID and Vietnam's Ministry of National Defence signed a memorandum of intent (MOI) to begin the decontamination of Bien Hoa airport. U.S. Ambassador to Vietnam Daniel J. Kritenbrink reportedly said at the MOI signing ceremony, "The United States looks forward to working with the Ministry of National Defence on this important initiative, deepening our partnership further, and building a prosperous future for both our countries." The MOI commits the two nations to work together to design a remediation program for the Bien Hoa airport.
USAID and the Ministry of National Defence signed a five-year, $183 million nonrefundable aid agreement on May 11, 2018, for the decontamination of Bien Hoa airport. At the time of the signing of the agreement, the project was projected to take 10 years at an estimated cost of $390 million. Approximately 500,000 cubic meters of soil, or nearly 50 hectares (123 acres) of land, are to be decontaminated.
In September 2018, the Ministry of National Defence signed a memorandum of understanding with the Japanese general contractor, Shimizu Corporation, to construct a decontamination factory at Bien Hoa airport. The factory reportedly will decontaminate the soil by a filtered sponge technique, and be capable of decontaminating 40 tons of soil per hour. The new technique is expected to cost about half as much as the in-pile thermal desorption used at Danang airport.
U.S. Secretary of Defense Jim Mattis visited Bien Hoa airport on October 17, 2018. During his tour of the former Agent Orange storage site, Secretary Mattis reportedly said, "We had promised to help … so this is America keeping her promise to remediate some of the past." He also reportedly stated prior to the visit, "I just want to get eyes on [the site] so when I go back and talk to Congress, I can tell them my impression with actually having seen the site."

	Issues Before Congress

Congressional interest in Agent Orange/dioxin in Vietnam has largely been focused on two issues. The first issue is determining the appropriate amount and type of assistance to provide to address the environmental damage and the health effects of dioxin contamination in Vietnam. The second issue is oversight of how such assistance has been utilized by the State Department and USAID.

		Funding Assistance

Congress and the Obama Administration demonstrated a common interest in providing assistance to address the environmental remediation of Agent Orange and dioxin in Vietnam; the Trump Administration has indicated its support for the Agent Orange projects in Vietnam. The State Department regularly has requested funding for decontamination of dioxin "hot spots" in Vietnam in its budget request to Congress.
As described above, Congress has generally appropriated funds for health and disability services for persons residing in areas sprayed by Agent Orange and otherwise contaminated with dioxin. The State Department and USAID have utilized those funds for various programs for persons with disabilities regardless of the cause. In many, but not all, cases, those programs were conducted in locations near known Agent Orange "hot spots." President Obama's budget requests to Congress did not include funding requests explicitly for health and disability assistance programs for areas sprayed with Agent Orange or otherwise contaminated with dioxin. The Obama Administration budget requests were for disability programs and/or "vulnerable groups."
The Consolidated Appropriations Act, 2019 ( P.L. 116-6 ) continues the past practice of designating funds for health and disability services for places contaminated with Agent Orange/dioxin. Section 7043(h)(2) of the act, states
Of the funds appropriated by this Act under the heading 'Development Assistance', not less than $12,500,000 shall be made available for health and disability programs in areas sprayed with Agent Orange and otherwise contaminated with dioxin, to assist individuals with severe upper or lower body mobility impairment or cognitive or developmental disabilities.
The Victims of Agent Orange Relief Act of 2019 ( H.R. 326 ) would "direct the Secretary of State, the Secretary of Health and Human Services, and the Secretary of Veterans Affairs to provide assistance for individuals affected by exposure to Agent Orange, and for other purposes." Section 3 would require the Secretary of State to "provide assistance to address the health care needs of covered individuals. Such assistance shall include the provision of medical and chronic care services, nursing services, vocational employment training, and medical equipment." "Covered individuals" is defined as Vietnamese residents affected by health issues related to their exposure to Agent Orange between January 1, 1961, and May 7, 1975, or is "the child or descendant of an individual" who was exposed to Agent Orange during the designated time period.
Under Section 3, the Secretary of State would also be required to provide assistance "to repair and rebuild substandard homes in Vietnam for covered individuals and the families of covered individuals." Section 4 would require the Secretary of State and the Secretary of Veterans Affairs to "identify and provide assistance to support research relating to health issues of individuals affected by Agent Orange."
Section 3 also would require the Secretary of State to provide assistance to "institutions in Vietnam that provide health care for covered individuals," and to "remediate those geographic areas of Vietnam that the Secretary determines contain high levels of Agent Orange." The section further states, "the Secretary of State shall give priority to heavily sprayed areas, particularly areas that served as military bases where Agent Orange was handled, and areas where heavy spraying and air crashes resulted in harmful deposits of Agent Orange."
Section 8 states, "Not later than 30 days after the last day of each fiscal quarter beginning on or after 18 months after the date of the enactment of this Act, the Secretary of State, the Secretary of Health and Human Services, and the Secretary of Veterans Affairs shall each submit to Congress a report on the implementation of the provisions of this Act applicable to such Secretary during the immediately preceding fiscal quarter."

		Oversight of Assistance

Beyond determining the level of funding for environmental remediation and the provision of health services to Agent Orange/dioxin-contaminated locations in Vietnam, Congress has overseen the utilization of appropriated funds. With regard to environmental remediation, congressional oversight has focused on the rising cost of the cleanup effort at Danang airport, and the potential implications for funding for the proposed cleanup of Bien Hoa. With regard to USAID's provision of related health services, congressional oversight has focused on what some Members perceive to be a slow pace at which available funds are being obligated and changes in USAID's approach to administering those funds.
As noted above, the estimated total cost of the environmental remediation of Danang airport rose from $33.7 million in 2010 to $116 million. Members could point to cost overruns at Danang airport when Congress looks ahead to possibly funding a similar environmental remediation project at Bien Hoa airport, where a USAID study indicated that approximately 500,000 m 3 of soil—about four to five times the amount at Danang—is contaminated.
Although the Danang airport cleanup experienced rising costs and delays, USAID was able to keep the project going and the funding flowing. USAID has not been as successful in utilizing the funds provided for health services to areas contaminated with Agent Orange/dioxin. According to information provided by USAID, 63.5% of the funds appropriated in FY2011 to FY2017 have been obligated. In addition, USAID's approach to utilizing health services funds has shifted from direct obligation by USAID, to establishing a cooperative agreement to administer the funds, and back again to direct obligation by USAID. Some observers question whether the health services funds are being used effectively, and in accordance with congressional priorities. The specific language in Section 7043(h)(2) of Consolidated Appropriations Act, 2019 ( P.L. 116-6 ) and H.R. 326 regarding health and/or disability assistance to Vietnam may in part reflect congressional dissatisfaction with State Department and USAID management of previously appropriated funds.

			Appendix. Text of Public Laws Appropriating Funds for Environmental Remediation and Health and Disability Services in Vietnam

Congress has included language in legislation indicating that it is appropriating funds for environmental remediation and health and disability services in Vietnam. The precise amounts appropriated, however, in most cases have been stipulated in either an accompanying report or explanatory statement. The table below provides the relevant text in the public law, as well as the associated language in the accompanying report or explanatory statement.

Output:
U.S. assistance to Vietnam for the environmental and health damage attributed to a dioxin contained in Agent Orange and other herbicides sprayed over much of the southern portion of the country during the Vietnam War remains a major bilateral issue. Between fiscal years (FY) 2007 and 2019, Congress appropriated nearly $255 million to address these two issues. In addition, the John S. McCain National Defense Authorization Act for Fiscal Year 2019 (P.L. 115-232) authorized the transfer of up to $15 million to the U.S. Agency for International Development (USAID) for the dioxin cleanup of the Bien Hoa Airbase.
Most of the appropriated funds have been used by USAID for the environmental cleanup of Danang airport, one of the major airbases used for storing and spraying the herbicides between 1961 and 1971. A lesser amount of the appropriated funds have been used by USAID for assistance to Vietnam's persons with disabilities, generally, but not always in the vicinity of Danang or other dioxin-contaminated areas.
Congressional interest in Agent Orange/dioxin in Vietnam has largely been focused on two issues. The first issue is determining the appropriate amount and type of assistance to provide to address the environmental damage and the health effects of dioxin contamination in Vietnam. The second issue is oversight of how such assistance has been utilized by the State Department and USAID.
In November 2017, the United States and Vietnam completed the environmental remediation of approximately 90,000 cubic meters (118,000 cubic yards) of contaminated soil and 60,000 cubic meters (78,000 cubic yards) of lower risk materials at Danang airport by a process known as in-pile thermal desorption (IPTD). Restoration and project closure operations were completed in November 2018. The project took six years, with an estimated overall cost of $116 million.
Field studies have identified a number of other areas in Vietnam contaminated with the dioxin associated with Agent Orange, including the airports near Bien Hoa and Phu Cat, as well as sections of the A Luoi Valley. In January 2018, U.S. and Vietnamese governments signed a memorandum of intent (MOI) to begin the cleanup of the Bien Hoa airport. According to a USAID study, the environmental cleanup of Bien Hoa airport could cost an estimated $137 million to $794 million, depending on what form of remediation is used.
The provision of health-related assistance to areas contaminated with Agent Orange/dioxin has raised questions about how USAID has utilized appropriated funds. By May 2017, USAID had obligated less than two-thirds of the appropriated funds for FY2011-FY2017. The funds have generally been used for disability assistance programs regardless of the cause of the disability, rather than for both health and disability programs targeting populations residing near Agent Orange/dioxin "hot spots."
While the obligations for environmental remediation activities generally have not been a matter of congressional concern, how USAID has obligated appropriations for health and disability activities has drawn some attention.
The Consolidated Appropriations Act, 2019 (P.L. 116-6) appropriated "not less than $20 million" for environmental remediation and "not less than $12.5 million … for health and disability programs in areas sprayed with Agent Orange and otherwise contaminated with dioxin." The Victims of Agent Orange Relief Act of 2019 (H.R. 326) would require the Secretary of State to provide assistance to individuals in Vietnam with health issues related to exposure to Agent Orange, as well as "to institutions in Vietnam that provide health care for covered individuals." The act would also require the Secretary of State to provide assistance "to remediate those geographic areas of Vietnam that the Secretary determines contain high levels of Agent Orange."

	Introduction

Water infrastructure issues, particularly regarding funding, continue to receive attention from some Members of Congress and a wide array of stakeholders. Localities are primarily responsible for providing wastewater and drinking water infrastructure services. According to the most recent estimates by states and the U.S. Environmental Protection Agency (EPA), expected capital costs for such facilities total $744 billion over a 20-year period. While some analysts and stakeholders debate whether these estimates understate or overstate capital needs, most agree that the affected communities face formidable challenges in providing adequate and reliable water infrastructure services.
Capital investments in water infrastructure are necessary to maintain high quality service that protects public health and the environment, and capital facilities are a major investment for local governments. The vast majority of public capital projects are debt-financed (i.e., they are not financed on a pay-as-you-go basis from ongoing revenues to the water utility). The principal financing tool that local governments use is the issuance of tax-exempt municipal bonds. At least 70% of U.S. water utilities rely on municipal bonds and other debt to some degree to finance capital investments. Beyond municipal bonds, federal assistance through grants and loans is available for some projects but is insufficient to meet all needs. Finally, public-private partnerships (P3s), which are long-term contractual arrangements between a public utility and a private company, currently provide only limited capital financing in the water sector. Although they are increasingly used in transportation and some other infrastructure sectors, especially P3s that involve private sector debt or equity investment in a project, most P3s for water infrastructure involve contract operations for operation and maintenance. Numerous drinking water utilities are privately owned and make significant private capital investments in water infrastructure, unlike the wastewater sector, in which facilities are generally owned by municipalities.
In recent years, Congress has considered several legislative options to help finance water infrastructure projects, including projects to build and upgrade wastewater and drinking water treatment facilities. Some Members have offered proposals that would amend, supplement, and/or complement the existing clean water and drinking water State Revolving Fund (SRF) programs. Other proposals would address water infrastructure issues outside the framework of the SRF programs.
In 2014, Congress established the Water Infrastructure Finance and Innovation Act (WIFIA) program, which creates a new mechanism of providing financial assistance for water infrastructure projects. The first section of this report provides an overview of the WIFIA program, including its origins, scope, and applicability. The second section describes WIFIA program appropriation levels and estimates of the amount of credit assistance the federal funding would provide. The third section discusses EPA's implementation of the WIFIA program, including recent developments. The fourth section identifies selected issues that may be of interest to policymakers.

	Program Overview

The WIFIA approach for supporting investment in water infrastructure is modeled after the Transportation Infrastructure Finance and Innovation Act (TIFIA) program, which was established in 1998 (see textbox below for further details). As the name suggests, only transportation projects are eligible for TIFIA assistance. The TIFIA program generated interest in creating a similar program for water infrastructure.
As discussed below, the Water Resources Reform and Development Act of 2014 (WRRDA 2014) established and authorized appropriations for the WIFIA program. Congress provided the first appropriations for EPA to offer credit assistance, such as direct loans, under the WIFIA program in FY2017. In 2018, America's Water Infrastructure Act of 2018 (AWIA) reauthorized appropriations for the program and amended certain WIFIA provisions.

		WRRDA 2014

WRRDA 2014 established a five-year WIFIA pilot program. The act authorized (1) EPA to provide credit assistance (loans or loan guarantees) for a range of drinking water and wastewater projects and (2) the U.S. Army Corps of Engineers to provide similar assistance for water resource projects, such as flood control or hurricane and storm damage reduction.
Congress provided appropriations to EPA to administer the WIFIA program in FY2014. Congress has not appropriated analogous funds to the Corps (nor has the Administration requested funds for a Corps WIFIA program) that would enable the Corps to implement a WIFIA program as laid out in WRRDA 2014. Regardless, this section identifies WIFIA provisions relating to both EPA and the Corps.
To implement the program, the act authorized appropriations of $175 million over five years to both EPA and the Corps (beginning with $20 million for each agency in FY2015 and increasing to $50 million in FY2019). Project costs must generally be $20 million or larger to be eligible for credit assistance. For projects in less populous communities (defined by WIFIA as populations of 25,000 or less), project costs must be $5 million or more. WIFIA credit assistance is available to
state infrastructure financing authorities; a corporation; a partnership; a joint venture; a trust; or a federal, state, local, or tribal government (or consortium of tribal governments).
In the case of projects carried out by private entities, such projects must be publicly sponsored. To meet this requirement, WIFIA allows a project applicant to demonstrate to the EPA or the Corps that the affected state, local, or tribal government supports the project. The maximum amount of a loan is 49% of eligible project costs, but the act authorizes EPA or the Corps to make available up to 25% of available funds each year for credit assistance in excess of 49% of project costs. Except for certain projects in rural areas, the total amount of federal assistance (i.e., WIFIA and other sources combined) may not exceed 80% of a project's cost.
Activities eligible for assistance under the WIFIA pilot program include project development and planning, construction, acquisition of real property, and carrying costs during construction. Categories eligible for assistance by EPA include
projects eligible for assistance through the clean water state revolving fund (CWSRF) and drinking water state revolving fund (DWSRF) programs (i.e., wastewater treatment and community drinking water facilities); enhanced energy efficiency of a public water system or wastewater treatment works; repair or rehabilitation of aging wastewater and drinking water systems; desalination, water recycling, aquifer recharge, or development of alternative water supplies to reduce aquifer depletion; prevention, reduction, or mitigation of the effects of drought; or a combination of eligible projects.
Categories eligible for assistance by the Corps include
flood control or hurricane and storm damage reduction projects, environmental restoration, coastal or inland harbor navigation improvement, or inland and intracoastal waterways navigation improvement.
The EPA Administrator or Secretary of the Army, as appropriate, determines project eligibility based on creditworthiness and dedicated revenue sources for repayment. Selection criteria include
the national or regional significance of the project, extent of public or private financing in addition to WIFIA assistance, use of new or innovative approaches, the amount of budget authority required to fund the WIFIA assistance, the extent to which a project serves regions with significant energy development or production areas, and the extent to which a project serves regions with significant water resources challenges.
Responding to concerns from some groups that WIFIA could impair and diminish support for clean water and drinking water SRF programs under the Clean Water Act and Safe Drinking Water Act (see discussion below), the act requires the EPA Administrator, when the agency receives applications for WIFIA assistance, to notify state infrastructure financing authorities and give them the opportunity to commit funds to the project.
WIFIA-assisted projects must use American-made iron and steel products. Projects must also comply with the prevailing wage requirements of the Davis-Bacon Act in the same manner that they would under the SRF provisions of the Clean Water Act.
In addition, the act directed EPA and the Corps to provide information on a website concerning applications and projects that have received assistance, and the Government Accountability Office must report to Congress (four years after enactment, i.e., June 10, 2018) on the program and provide recommendations for continuing, changing, or terminating the WIFIA program. As discussed below, AWIA extended the deadline for this report.

		AWIA 2018

AWIA, enacted on October 23, 2018, amended WIFIA in several ways:
It removed WIFIA's designation as a pilot program. It authorized appropriations of $50.0 million for each of FY2020 and FY2021 for EPA program implementation. It authorized EPA to administer the WIFIA program for relevant agencies (through an interagency agreement), specifically directing EPA to enter into such an agreement with the commissioner of the Bureau of Reclamation within the Department of the Interior. It required the Government Accountability Office to prepare a report for Congress by October 23, 2021.
In addition, AWIA authorized an additional $5 million in WIFIA appropriations to provide credit assistance to state finance authorities to support combined projects eligible for assistance from the CWSRF and DWSRF. This additional appropriation authority is available for FY2020 and FY2021 and is available only if (1) Congress appropriates funding for both the CWSRF and the DWSRF at FY2018 levels or 105% or more of the previous year's funding, whichever is greater, and (2) EPA receives at least $50.0 million in WIFIA appropriations. State financing authorities may use funding from WIFIA appropriations to cover 100% of project costs, in contrast to the 80% federal financial assistance cap that applies to most WIFIA-financed projects.

	Appropriations

For each of FY2015 and FY2016, Congress provided $2.2 million for EPA to hire staff and design the new water infrastructure assistance program. In FY2017, Congress provided the first appropriations to cover the subsidy cost of the program, thus allowing implementation of WIFIA (i.e., making project loans). Congress provided a total of $30 million for the WIFIA program for FY2017 through two appropriations acts:
The Further Continuing and Security Assistance Appropriations Act, 2017 ( P.L. 114-254 ), enacted on December 10, 2016, provided the first appropriation of funds to cover the subsidy cost of the program. P.L. 114-254 appropriated $20 million to EPA to begin making loans and allowed the agency to use up to $3 million of the total for administrative purposes. The act authorized EPA to use these appropriations to subsidize costs to provide credit assistance not to exceed $2.1 billion. The Consolidated and Further Continuing Appropriations Act, 2017 ( P.L. 115-31 ), enacted on May 5, 2017, provided an additional $8 million for EPA to apply toward loan subsidy costs and $2 million for EPA's administrative expenses. The act authorized EPA to use funds to guarantee as much as $976 million in direct loans.
For FY2018, the Consolidated Appropriations Act, 2018 ( P.L. 115-141 ), provided $63 million for the WIFIA program (including $8 million for administrative costs). The act authorized EPA to use funds to guarantee as much as $6.71 billion in direct loans. EPA estimated that its budget authority ($55 million) would provide approximately $5.5 billion in credit assistance.
For FY2019, the Consolidated Appropriations Act, 2019 ( P.L. 116-6 ) provided $68 million for the WIFIA program, including $8 million for administrative costs. The act authorized EPA to use funds to guarantee as much as $7.31 billion in direct loans. EPA estimated that its budget authority ($60 million) would provide approximately $6 billion in credit assistance.
 Figure 1 illustrates the WIFIA appropriations for administrative purposes and for loan subsidy costs between FY2017 and FY2019. The appropriations acts for FY2017 through FY2019 state that the appropriations for the subsidy costs would be available until expended. In contrast, fiscal year appropriations for WIFIA administrative costs are not available after specific dates.
As discussed above, WRRDA 2014 authorized a parallel program for water resources projects to be administered by the Corps. Congress has not yet appropriated funds (nor has the Administration requested funds for a Corps WIFIA program) that would enable the Corps to begin preparations or begin making WIFIA loans under the authority in the 2014 statute.

	EPA Implementation

EPA began preparing for implementation of the WIFIA program, including through a series of public listening sessions in several U.S. cities, in 2014. The intended audience was municipal, state, and regional water utility officials; private sector financing professionals; and other interested organizations and parties. The purpose was to discuss project ideas, potential selection and evaluation criteria, and numerous other implementation issues.
In 2016, EPA issued two rules intended to explain and clarify some provisions of the program and establish guidelines for the application process. One was an interim final rule that sets guidelines for the application and selection of projects, defines the requirements for credit assistance, and defines reporting requirements and a fee collection structure. In this rule, EPA said that it would initially give funding priority to four types of projects:
1. adaptation to extreme weather and climate change; 2. enhanced energy efficiency of wastewater treatment works and public water systems; 3. green infrastructure; and 4. repair, rehabilitation, and replacement of infrastructure and conveyance systems.
Through the second rulemaking, EPA proposed a fee structure for WIFIA (application fee, credit processing fee, and servicing fee). EPA finalized this rule in June 2017. WIFIA authorizes EPA to charge fees to recover all or a portion of the agency's costs administering the program. EPA's final rule requires a nonrefundable fee for each project that is invited to submit a full WIFIA application. The application fee is $100,000, or $25,000 for projects serving small communities. The fees are not required in connection with submission of letters of interest but would be required for projects that EPA expects might reasonably proceed to closing on a credit assistance agreement. Enacted December 16, 2016, the Water Infrastructure Improvements for the Nation (WIIN) Act ( P.L. 114-322 , Section 5008(c)) amended WIFIA to allow fees to be financed as part of the loan at the request of an applicant. In 2018, AWIA amended WIFIA to clarify that state financing authorities cannot pass along application fees on to the parties that utilize WIFIA assistance.
After EPA received its first appropriations to cover loan subsidy costs, it announced its first round of funding for the WIFIA program in January 2017. Additional rounds of funding have followed with each fiscal year's enacted appropriations.
 Table 1 provides details for each of EPA's funding rounds, including the project priorities EPA listed in its annual funding notices, the number of letters of interest submitted, selected projects, and loans closed.

	Selected Issues

		Subsidy Amount for Credit Assistance

From the federal perspective, an advantage of the WIFIA program is that it can provide a large amount of credit assistance relative to the amount of budget authority provided. In federal budgetary terms, WIFIA assistance has less of an impact than a grant, which is not repaid to the U.S. Treasury.
The volume of loans and other types of credit assistance that the program can provide is determined by the size of congressional appropriations and calculation of the subsidy amount. WIFIA defines the "subsidy amount" as follows:
The amount of budget authority sufficient to cover the estimated long-term cost to the Federal Government of a Federal credit instrument, as calculated on a net present value basis, excluding administrative costs and any incidental effects on governmental receipts or outlays in accordance with the Federal Credit Reform Act of 1990 (2 U.S.C. 661 et seq.).
The subsidy amount, which is often expressed in percentage terms or as a ratio (i.e., subsidy rate), largely determines the amount of credit assistance that can be made available to project sponsors. For example, if a project's subsidy rate is 10% and is the only charge against available budget authority, a $20 million budgetary allocation could theoretically support a $200 million loan. A lower subsidy rate would support a larger loan amount.
As a reference point, the Office of Management and Budget (OMB) identified a TIFIA subsidy rate of 6.30% for direct loans in FY2020. Proponents of WIFIA have argued that loans for water projects are likely to be less risky than transportation projects, because water utility collections for services (i.e., water rates) provide an established revenue stream and repayment mechanism; thus the subsidy cost would be lower and the amount of credit assistance higher (per dollar of budget authority). Adding caution, however, analysts note that, even with stable revenue mechanisms, some communities and water utilities have recently experienced problems with borrowing and bond repayments, so repayment of a WIFIA loan is not a certainty.
In the Trump Administration's FY2020 budget proposal, OMB estimated a 0.91% subsidy rate for WIFIA. This equates to a 1:110 ratio. At this subsidy rate, a $10 million appropriation could support a direct loan (or loans) totaling $1.10 billion. However, this subsidy rate is an estimate for budgetary purposes. In the context of WIFIA implementation, subsidy rates are project-specific. EPA stated that the subsidy rate
is used for budgetary purposes and provides an estimate for what will be available for loans each year based on the anticipated riskiness of the future loan portfolio. The actual ratio will be determined for each project at the time of loan obligation. Project A with a higher credit quality would consume less of the credit subsidy than Project B with a lower credit quality, even if the projects are otherwise identical. Each applicant will be scored independently.

		Loan Interest Rates and Default Risk

The WIFIA program provides capital at a low cost to the borrower, because even though the interest on 30-year Treasury securities is taxable, Treasury rates can be less expensive than rates on traditional tax-exempt municipal debt. Moreover, WIFIA financing may be characterized as patient capital, because loan repayment does not need to begin until five years after substantial completion of a project, the loan can be for up to 35 years from substantial completion, and the amortization schedule can be flexible. In addition, there is less perceived investment risk, because the project has been determined to be creditworthy (i.e., there is a revenue stream for repayment).
Additionally, the WIFIA program has the potential to limit the federal government's exposure to default by relying on market discipline through creditworthiness standards and encouraging private capital investment.
On the other hand, the Congressional Budget Office (CBO) has argued that the federal government underestimates the cost of providing credit assistance under such programs because it excludes
the cost of market risk—the compensation that investors require for the uncertainty of expected but risky cash flows. The reason is that the [Federal Credit Reform Act] requires analysts to calculate present values by discounting expected cash flows at the interest rate on risk-free Treasury securities (the rate at which the government borrows money). In contrast, private financial institutions use risk-adjusted discount rates to calculate present values.
In an effort to encourage nonfederal and private sector financing, WIFIA funding assistance generally cannot exceed 49% of project costs. In addition, WIFIA limits all sources of federal assistance to no more than 80% of a project's cost.

		Interactions with Existing Water Financing Programs

In general, the WIFIA program is designed to support larger infrastructure projects with eligible costs exceeding $20 million. For this reason, some have argued that the WIFIA program complements existing water infrastructure financing tools—SRF programs under the Clean Water Act and Safe Drinking Water Act—which are often used for smaller-scale projects.
Policymakers set a lower minimum threshold for project costs ($5 million) for WIFIA projects in communities with populations less than 25,000. One of 12 projects selected in the FY2017 funding round is located in a less populous community (Morro Bay, CA). Two of the 39 projects in the FY2018 funding round are located in less populous communities (Frontenac, KS, and Cortland, NY).
Generally, the level of interest from less populous communities in WIFIA financing is uncertain, particularly considering the other financing options that may be available. The U.S. Department of Agriculture has a variety of water and waste disposal programs to provide loans and grants for wastewater and drinking water infrastructure in rural communities (10,000 people or fewer). In addition, both of the SRF programs authorize states to provide subsidized financial assistance—such as principal forgiveness, negative interest loans, or a combination—under certain conditions. Appropriations acts in recent years have required states to use minimum percentages of their federal grant amounts to provide additional subsidization. The FY2019 appropriations act requires 10% of the CWSRF grants and 20% of the DWSRF grants to be used "to provide additional subsidy to eligible recipients in the form of forgiveness of principal, negative interest loans, or grants (or any combination of these)."
WIFIA financing can potentially support smaller projects by grouping, or aggregating, them through a single application for financial assistance. For example, during the first round of WIFIA funding (FY2017), one of the 12 entities selected to submit a loan application was the Indiana Finance Authority, which administers the clean water and drinking water SRF programs in Indiana. Indiana's prospective WIFIA loan would provide $436 million to support multiple projects in the state.
A major source of debate among opponents and proponents has been and continues to be potential impacts of WIFIA on funds for the Clean Water Act and Safe Drinking Water Act SRF programs. Several groups representing state environmental officials opposed the establishment of a WIFIA program (in the 113 th Congress). They argued that WIFIA funding could result in reduced spending on the SRF programs, which are capitalized by federal appropriations. States are concerned that WIFIA would likely be funded (through congressional appropriations) to the detriment of the SRF programs.
On the other hand, water utility groups that support WIFIA have argued that it would complement, not harm, existing SRF programs. In their view, WIFIA will provide a new funding opportunity for large water infrastructure projects that are unlikely to receive SRF assistance. As described above, in part to address concerns about impacts of WIFIA on the SRF programs, WIFIA requires EPA to notify state infrastructure financing authorities about WIFIA application and gives state infrastructure financing authorities an opportunity to commit funds to the project. Nevertheless, some states and environmental advocacy groups remain concerned that WIFIA will compete with SRFs for congressional funding and that WIFIA will not prioritize public health or affordability, as the SRFs can. The 2016 Water Infrastructure Improvements for the Nation Act includes a "sense of the Congress" that WIFIA funding should be in addition to robust funding for the SRFs.

		Potential Federal Revenue Loss from Tax-Exempt Bonds

Enacting the WIFIA program raised a federal budgetary and revenue issue. Legislation reported by congressional committees is typically scored by the CBO for the effects on discretionary and mandatory, or direct, spending and by the Joint Committee on Taxation (JCT) for effects on revenue. The initial CBO cost estimate for S. 601 , as approved by the Environment and Public Works Committee in April 2013, concluded that the WIFIA provisions would cost $260 million over five years. In addition, it would result in certain revenue loss to the U.S. Treasury; thus, pay-as-you-go procedures would have applied to the bill. CBO cited the JCT estimate that enactment of the bill would reduce revenues by $135 million over 10 years, because states would be expected to issue tax-exempt bonds for water projects in order to acquire additional funds not covered by WIFIA assistance. To avoid the pay-as-you-go requirement in the bill, the committee added a provision to S. 601 to prohibit recipients of WIFIA assistance from issuing tax-exempt bonds for the non-WIFIA portions of project costs. CBO re-estimated the bill and concluded that, because the change would make the WIFIA program less attractive to entities, most of which rely on tax-exempt bonds for project financing, the cost of the bill would be $200 million less over five years. CBO also said that the bill would have no impact on revenues, because the demand for federal credit would be lower without the option of using tax-exempt financing. WRRDA 2014 retained the bar on tax-exempt financing for WIFIA-assisted projects. Thus, the apparent solution to one issue in the legislation—potential revenue loss to the U.S. Treasury—raised a different kind of issue for entities seeking WIFIA credit assistance, because tax-exempt municipal bonds are the principal mechanism used by local governments to finance water infrastructure projects.
The restriction was widely criticized by potential users of WIFIA assistance. In their view, the bond financing restriction in WRRDA 2014, together with the provision that caps WIFIA assistance at 49% of project costs, would make it very difficult to finance needed projects. Congressional interest in addressing the tax-exempt bond restriction was soon evident. For example, H.R. 1710 in the 114 th Congress proposed to make an exception from the limitation on use of tax-exempt bonds for WIFIA loans made to finance water infrastructure projects in states in which the governor has issued a state of drought emergency declaration.
More generally, in July 2015, the Senate passed H.R. 22 , a bill to reauthorize highway and transportation programs for six years. It included repeal of the provision in P.L. 113-121 that limits any project receiving federal credit assistance under the WIFIA program from being financed with tax-exempt bonds. However, repeal of the provision raised similar revenue questions to those that arose in connection with P.L. 113-121 . CBO's report on S. 1647 (the Senate Environment and Public Works Committee's bill, which was the basis of Senate-passed H.R. 22 ) stated that the Joint Committee on Taxation (JCT) estimated that repealing the WIFIA limitation would increase states' issuance of tax-exempt bonds for water projects and would decrease federal revenues by $17 million over the FY2016-FY2025 period. Further, CBO estimated that the change would increase demand for federal credit under the WIFIA program, resulting in additional spending stemming from the appropriation levels authorized in P.L. 113-121 . Consequently, CBO estimated that implementing the WIFIA program would cost $146 million over the FY2016-FY2025 period.
The issue of identifying offsets, or "pay-fors," for the estimated federal revenue loss was addressed in the conference agreement on H.R. 22 , the FAST Act ( P.L. 114-94 ). CBO estimated that the conference agreement included offsets to fully cover the cost of the bill by reducing spending or raising revenues. Thus, the enacted bill retained the provision repealing the tax-exempt bond financing restriction on WIFIA assistance.

Output:
The Water Infrastructure Finance and Innovation Act (WIFIA) program provides financial assistance for water infrastructure projects, including projects to build and upgrade wastewater and drinking water treatment systems. Congress established the WIFIA program in the Water Resources Reform and Development Act of 2014 (WRRDA 2014, P.L. 113-121).
The WIFIA concept is modeled after a similar program that finances transportation projects, the Transportation Infrastructure Finance and Innovation Act (TIFIA) program. Proponents of the WIFIA approach, including water utility organizations, cite several potential benefits:
WIFIA provides credit assistance to large water infrastructure projects that may otherwise have difficulty obtaining financing. WIFIA provides credit assistance, namely direct loans, at U.S. Treasury rates, potentially lowering the cost of capital for borrowers. WIFIA assistance has less of a federal budgetary effect than conventional project grants that are not repaid, because only the subsidy cost of a loan (representing the presumed default rate on loans) is required to be appropriated. WIFIA support limits the federal government's exposure to default, because projects must be found creditworthy with a revenue stream for repayment to be eligible for assistance.
On the other hand, opponents of the WIFIA approach, including organizations that represent state environmental agency officials, have cited several concerns:
Federal funding for a WIFIA program could have a detrimental effect on federal support for established State Revolving Fund (SRF) programs that provide the largest source of water infrastructure assistance today. If WIFIA funding resulted in a decrease in SRF assistance, smaller projects may face financing challenges. The Congressional Budget Office has warned that the future costs of a WIFIA program to the federal budget may be underestimated.
America's Water Infrastructure Act of 2018 (AWIA; P.L. 115-270), enacted on October 23, 2018, removed the pilot designation from the WIFIA program, reauthorized appropriations, and revised provisions related to program administration.
Appropriations for the WIFIA program have increased since its inception, allowing EPA to provide increasing amounts of credit assistance each year:
FY2017 appropriations totaled $30 million. FY2018 appropriations totaled $63 million. FY2019 appropriations totaled $68 million.
On April 5, 2019, EPA announced a third round of WIFIA funding, inviting prospective borrowers to submit letters of interest to EPA. From these submittals, the agency will select projects for funding. EPA estimated that its budget authority would provide approximately $6 billion in credit assistance.
