Headquartered in Washington, D.C., the Corps has eight divisions established generally according to watershed boundaries and 38 districts that carry out its Civil Works program. Corps headquarters primarily develops policies and provides agency oversight. The Assistant Secretary of the Army for Civil Works, appointed by the President, sets the strategic direction for the agency and has principal responsibility for the overall supervision of functions relating to the Civil Works program. The Chief of Engineers—a military officer—oversees the Corps’ civil works and military missions. The eight divisions—Great Lakes and Ohio River, Mississippi Valley, North Atlantic, Northwestern, Pacific Ocean, South Atlantic, South Pacific, and Southwestern—coordinate Civil Works projects in the districts within their respective divisions. Corps districts are responsible for planning, engineering, constructing, and managing Civil Works projects. Congress established the Section 219 program in the 1992 WRDA, which authorized the Corps to provide planning and design assistance to nonfederal sponsors in carrying out 18 environmental infrastructure projects, located in certain specified locations around the United States. For example, the 1992 WRDA authorized the Corps to provide assistance for a combined sewer overflow treatment facility for the city of Atlanta, Georgia. In subsequent acts, Congress authorized the Corps to provide construction assistance for Section 219 projects, in addition to planning and design, and significantly expanded the number of authorized projects. From 1992 through 2007, Congress authorized a total of 310 Section 219 projects, with the most recent and largest number of project authorizations occurring in 2007 (see table 1). For Section 219 projects, Congress specifies the geographic location (e.g., city, county), amount of authorized dollars, and purpose or scope of the project (e.g., development of drainage facilities to alleviate flooding problems). In general, Section 219 projects fall into one or more of the following types of projects: Drinking water treatment and distribution. Projects that build water treatment plants, water storage tanks, and water distribution lines. Wastewater treatment. Projects that build sewage treatment plants, wastewater collection systems, and facilities that purify treated wastewater for irrigation and other purposes. Stormwater management. Projects that help improve the management of storm sewers, eliminate or control sewer overflows, and address flooding. According to Corps data, of the 310 originally authorized Section 219 projects, 58 have been deauthorized and were no longer active, as of November 2018. The Corps is required by the 1986 WRDA, as amended, to annually identify all authorized projects that have not received obligations in the preceding 5 full fiscal years and submit that list to Congress. If funds are not obligated for planning, design, or construction of a project on that list during the next fiscal year, the project is deauthorized. The Secretary of the Army publishes a list of deauthorized projects in the Federal Register. Based on this process, the Corps considered deauthorizing 197 additional Section 219 projects in its fiscal year 2017 report to Congress. However, the 2018 WRDA provided that the projects identified for deauthorization in the Corps’ fiscal year 2017 report were generally not to be deauthorized unless they met certain additional requirements. The Corps allocates funding for Section 219 projects and other environmental infrastructure programs from the construction account. That account generally receives no-year appropriations through the Energy and Water Development Appropriations Act—meaning the appropriation remains available for obligation for an indefinite period of time. Prior to fiscal year 2012, the conference reports accompanying the annual Energy and Water Development Appropriations Acts generally listed individual Section 219 projects and specific allocations of funding for each project. However, since fiscal year 2012, Congress has not provided allocation direction for individual projects, but instead generally has designated an amount in reports and joint explanatory statements for environmental infrastructure overall, ranging from about $30 million to $55 million annually. According to Corps data, from fiscal years 1992 through 2017, the Corps expended over $440 million on Section 219 projects. Similar to other Civil Works projects, the Corps generally becomes involved in Section 219 projects when a nonfederal sponsor contacts the Corps for assistance on an authorized project. Corps districts gather additional information on the project from the nonfederal sponsor and determine if it is ready to be initiated. Once the Corps receives an appropriation from Congress, the agency decides whether to allocate funding to the project. If the project is selected to receive funding, it enters the preconstruction engineering and design phase. The purpose of this phase is to complete any additional planning studies and all of the detailed technical studies and designs—such as environmental impact studies—needed to begin construction. During this phase, the Corps also completes an environmental assessment of the proposed project. To initiate construction, the Corps and the nonfederal sponsor sign a project partnership agreement that specifies how the parties will collaborate, their respective roles and responsibilities, and the terms and conditions under which they will execute their responsibilities. The project partnership agreement typically requires the sponsor to provide without cost to the U.S. government all lands, easements, rights-of-way, relocations, and disposal areas necessary for the construction and subsequent maintenance of the project; maintain and operate the project after completion without cost to the provide cash or work-in-kind contributions to make the sponsor’s total contribution equal to 25 percent if the value of the sponsor’s land contribution does not equal or exceed 25 percent of the project cost. The Corps manages the construction phase, contracting out construction work to private engineering and construction contractors. Throughout the construction phase, the Corps oversees the contractors’ work, performing routine inspections to ensure it meets the Corps’ design and engineering specifications. During construction, the Corps, the nonfederal sponsor, and the private contractor typically appoint representatives to a project coordination team that meets regularly until the period of construction ends. Upon notification by the District Engineer that construction is complete, the nonfederal sponsor is responsible for operations and maintenance. Figure 1 shows the major steps in managing a Section 219 project. The Corps expended about $81 million on 29 Section 219 projects from fiscal years 2013 through 2017, which included various types of projects such as drinking water treatment and distribution, wastewater treatment, and stormwater management. Examples of these projects include the following: Drinking Water Treatment and Distribution. The Corps manages a Section 219 project that includes the development of water desalination infrastructure in various sections of the South Perris community, located east of Los Angeles, California. In general, the South Perris area relies on a mixture of groundwater and water imported from different sources, including the Colorado River. According to the Corps’ environmental assessment, various factors, such as drought, caused the community to supplement its drinking water supply through increased use of groundwater; however, the groundwater in the area historically contained high salt content. Since the project’s authorization in fiscal year 2001 through fiscal year 2017, the Corps has helped construct groundwater wells and pipelines, which connect to drinking water treatment facilities that reduce the amount of salt in the water (see fig. 2). According to the nonfederal sponsor for the South Perris project, the overall project has provided benefits such as creating a local potable water source to meet anticipated population growth and reducing the community’s dependence on imported water. Wastewater Treatment. The Corps manages a Section 219 project that includes the rehabilitation of sewer lines within the metropolitan area of St. Louis, Missouri. The city’s wastewater system dates back to the 1800s and lacks the capacity to handle large flows. From the project’s authorization in fiscal year 1999 through fiscal year 2017, the Corps has assisted the community, among other things, in sewer rehabilitation of deep tunnels. According to documentation from the Corps’ St. Louis District, the rehabilitation of sewers is important in protecting the health and safety of the public, given the risk of untreated sewage being discharged into the environment. Stormwater Management. The Corps manages a Section 219 project that involves the development of stormwater infrastructure, among other things, across a five-county region (Calumet region) in northern Indiana. For example, flooding is a widespread problem in the region and it has affected commercial corridors, including within Gary, Indiana. From the project’s authorization in fiscal year 1999 through fiscal year 2017, the Corps has been assisting the region with measures to alleviate flooding, such as constructing stormwater storage areas under the street (see fig. 2). According to a nonfederal sponsor we interviewed, the Corps’ efforts in the Calumet region have offered benefits to local communities by, among other things, improving storm drainage in an area that experienced flooding during heavy rainfall. The 29 Section 219 projects with expenditures from fiscal years 2013 through 2017 were located in different parts of the country and managed by six Corps divisions, although the majority of the projects were under the South Pacific Division (10 of the 29 projects) and Great Lakes and Ohio River Division (eight of the 29 projects). The five states with the largest number of projects during this period were California, with nine Section 219 projects; Virginia, with three Section 219 projects; and Michigan, Pennsylvania, and Mississippi, each with two Section 219 projects. These projects varied in terms of the geographic area covered, such as a city, county, or region (e.g., multiple counties). Based on the project descriptions we reviewed, 10 of the projects focused on the environmental infrastructure needs of cities, nine focused on counties and 10 on regions. Projects that cover a broad geographic area, such as those at the county or regional level, generally consist of different types of subprojects. For example, the Cook County, Illinois Section 219 project included several subprojects, such as the construction of water mains and sewer improvements in different areas across the county. Most of the Section 219 projects (24 of the 29 projects) were authorized in 2000 or earlier and were ongoing as of November 2018. Only one of the 29 projects was completed; the project in St. Croix Falls, Wisconsin, was completed in fiscal year 2014. For the St. Croix Falls project, the Corps assisted with improvements to a wastewater treatment plant, such as installing equipment to screen out large solids that otherwise would be released into the St. Croix River. Of the 28 remaining projects that were ongoing, as of November 2018, 17 were in the construction phase, and 11 were in the preconstruction engineering and design phase. Table 2 summarizes information on the 29 projects with expenditures from fiscal years 2013 through 2017 by division and district. See appendix I for additional information on each project, including a detailed description and the total amount of expenditures from fiscal years 2013 through 2017. As previously noted, the Corps spent about $81 million on these 29 Section 219 projects from fiscal years 2013 through 2017. During that period, expenditures by fiscal year ranged from about $11 million to $22 million. Divisions with the largest percentage of overall expenditures from fiscal years 2013 through 2017 were the South Atlantic Division (36 percent) and Mississippi Valley Division (25 percent). The divisions with the smallest percentage of overall expenditures during the period were the North Atlantic Division (less than 1 percent) and Southwestern Division (4 percent). Table 3 summarizes overall expenditures from fiscal years 2013 through 2017 by division and fiscal year. Of the 29 projects with expenditures from fiscal years 2013 through 2017, 15 projects expended less than $1 million each, representing a total of $2.3 million. The majority of these projects (10 of the 15 projects) were in the preconstruction engineering and design phase. For example, as part of the Cambria, California, project, the Corps expended about $244,000 on preconstruction engineering and design activities, such as evaluating the environmental impacts of constructing a seawater desalination facility. In addition, for the Cumberland County, Tennessee, project, the Corps expended about $261,000 on planning and design for water supply projects. In comparison, 14 of the 29 projects expended more than $1 million each over the same time period, representing a total of $78.2 million. In particular, the Corps spent over half of the funding during this time period on four projects: Calumet Region in Indiana; DeSoto County, Mississippi; Jackson County, Mississippi; and Lakes Marion and Moultrie in South Carolina (see fig. 3). These projects generally consisted of multiple subprojects and covered a wide geographic area. For example, the Calumet Region project has involved over 25 subprojects since its authorization in fiscal year 1999 through August 2018. Through these subprojects, the Corps has managed various activities, including replacing drinking water lines, improving wastewater treatment plants, and installing stormwater infrastructure in a number of cities across Indiana. Additionally, the Lakes Marion and Moultrie project in South Carolina has included a range of subprojects, such as construction of a water treatment plant, construction of a water tower, and installation of water transmission lines across six counties. The Corps generally follows its standard budget process for prioritizing funding for the Section 219 program. This process involves ranking Section 219 projects for funding by all three levels of the Corps’ organization—districts, divisions, and headquarters. District officials identify Section 219 projects, including subprojects, and other environmental infrastructure projects for potential funding; enter a numerical ranking for each project in the Civil Works Integrated Funding Database; and submit the information to the division through the database. Division officials receive the rankings from each of the multiple districts in the division. Division officials then re-rank the Section 219 and other environmental infrastructure projects from all of their districts against one another. Division officials enter the numerical ranking for all projects across all their districts into the Civil Works Integrated Funding Database and submit the information to headquarters through the database. Headquarters officials receive the rankings from each division. They re-rank the projects from all divisions against each other to generate the final nationwide rankings. Based on the final rankings, not all Section 219 and other environmental infrastructure projects that the divisions submitted will receive funding. Headquarters officials then determine a funding amount for each Section 219 project selected to receive funding and publish these decisions in the agency’s annual work plan. After headquarters publishes the annual work plan, headquarters officials begin to allocate funding to Section 219 projects. However, the Corps does not have written criteria to guide the ranking of Section 219 projects, in contrast to other types of projects. Specifically, in our December 2018 report, we found that the Corps uses written criteria—such as the rate of economic return, populations at risk, and economic impact—to prioritize funding for core mission areas, such as flood risk management and navigation projects. While Corps budget guidance indicates the criteria each core mission area should use in the ranking process, it does not specify criteria for Section 219 or other environmental infrastructure projects. In the absence of written criteria, Corps officials use their discretion on how to rank Section 219 projects for funding, according to Corps headquarters officials. When ranking Section 219 projects for funding, officials in each of the districts we interviewed generally consider whether Section 219 projects can be completed within the fiscal year. However, we found that the districts vary in terms of whether other factors are considered and what those factors are. Specifically, One district considers the level of congressional support and the potential public health impacts of the project. Another district considers the level of congressional support and the dollar value of the project. A third district only considers whether the project can be completed within the fiscal year. At the division level, officials we interviewed stated that they consider, among other things, the level of congressional support for the projects; however, to a large extent they rely on the rankings provided by their respective districts. Headquarters officials said that they primarily focus on ensuring that projects are geographically dispersed across the divisions when assigning final rankings for Section 219 projects. In recent years, congressional direction has indicated that the Corps, when allocating funding, is to consider giving priority for environmental infrastructure projects that have certain characteristics. For example, the Joint Explanatory Statement accompanying the Consolidated Appropriations Act in 2017 directed the Corps to consider characteristics such as projects: with the greater economic impact; in rural communities; in communities with significant shoreline and instances of runoff; in or that benefit counties or parishes with high poverty rates; and in financially distressed municipalities. Corps headquarters, division, and district officials we interviewed said that while they are generally aware of this congressional direction, they do not use it to guide the Section 219 ranking process. According to a division official, written criteria would be helpful for ranking projects across multiple districts and would clarify procedures for new staff. Officials we interviewed in the three districts said, in general, written criteria would clarify the ranking process. For example, one Corps district official stated that written criteria would provide standardization to the ranking process, ensuring that each district is focused on the highest priorities of the agency. According to Corps headquarters officials, although they see value in having written criteria to prioritize Section 219 funding, they have not developed such criteria because the agency considers Section 219 projects to be outside the agency’s core mission areas, such as flood control. According to a 2008 Corps report to Congress, “Funds provided to the Corps for wastewater treatment and municipal and industrial water supply projects necessarily reduce the amount of funds that instead could be used for the primary mission areas of the Corps. Thus, provision of Civil Works funding for these environmental infrastructure programs negatively affects the Corps’ ability to meet critical mission needs…such as restoring nationally significant ecosystems.” Headquarters officials confirmed that this report accurately reflects the agency’s current position. Corps officials also stated that developing written criteria has not been a priority because Section 219 projects represent a small percentage of the agency’s overall Civil Works budget. Federal standards for internal control states that agencies should use quality information to achieve their objectives by identifying information requirements. The federal standards also call for agencies to design control activities to achieve objectives and respond to risks, such as by clearly documenting internal control in management directives, administrative policies, or operating manuals. By establishing written criteria, the Corps would have greater assurance that its project selections align with a clear set of priorities, such as the characteristics identified in recent congressional direction for the agency to consider when selecting Section 219 projects for funding. Since the inception of the Section 219 program in 1992, the Corps has spent over $440 million on water infrastructure projects across its divisions and districts. However, the Corps has not developed written criteria for ranking Section 219 projects for funding as it has for other Civil Works programs within the agency’s core mission areas. Consequently, officials at the district, division, and headquarters levels are using their discretion regarding which factors to consider in ranking Section 219 projects for funding. Further, Congress has provided direction to the Corps on which characteristics to consider in prioritizing Section 219 funding; however, Corps officials stated that they do not use it to guide their ranking of Section 219 projects. By establishing written criteria, the Corps would have greater assurance that its project selections align with a clear set of priorities, such as the characteristics identified in recent congressional direction for the agency to consider when selecting Section 219 projects for funding. The Secretary of the Army should direct the Chief of Engineers and Commanding General of the U.S. Army Corps of Engineers to develop written criteria for ranking Section 219 projects for funding, taking into account a clear set of priorities, such as those identified by recent congressional direction. We provided a draft of this report to the Department of Defense for review and comment. In its written comments, reprinted in appendix II, the department concurred with our recommendation and described the actions they plan to take. Specifically, the Corps will develop and document a more rigorous set of priorities in line with those identified by recent Congressional direction. The department also provided technical comments, which we incorporated as appropriate. We are sending copies of this report to the appropriate congressional committees, the Secretary of Defense, the Chief of Engineers and Commanding General of the U.S. Army Corps of Engineers, and other interested parties.

Summary: Under Section 219 of the 1992 Water Resources Development Act, as amended, Congress authorized the Corps to provide assistance for the design and construction of environmental infrastructure projects, known as Section 219 projects. Such projects include the development of water transmission lines. Congress typically provides a lump sum appropriation for the Corps' construction account, out of which Section 219 and other environmental infrastructure projects are funded. GAO was asked to review projects carried out under the Section 219 program. This report examines (1) the number and type of Section 219 projects and expenditures from fiscal years 2013 through 2017, and (2) how the Corps prioritizes funding for Section 219 projects. GAO reviewed relevant federal laws and agency guidance; analyzed agency data for fiscal years 2013 through 2017, the most recent time period for which data were available; and interviewed agency officials at headquarters, three divisions, and three districts–selected based on geographic distribution and the amount of Section 219 project expenditures. From fiscal years 2013 through 2017, the most recent available data, the U.S. Army Corps of Engineers (Corps) spent approximately $81 million on 29 Section 219 projects to develop drinking water, wastewater, and stormwater infrastructure. For example, through the St. Croix Falls, Wisconsin Section 219 project, the Corps assisted with improvements to a wastewater treatment plant. Of the 29 projects, the Corps spent over half of the funding during this period on four projects: (1) Calumet Region, Indiana; (2) Desoto County, Mississippi; (3) Jackson County, Mississippi; and (4) Lakes Marion and Moultrie, South Carolina. The Corps generally follows its standard budget prioritization process—which involves districts, divisions, and headquarters ranking each project and headquarters making final funding decisions—to prioritize Section 219 funding. However, the Corps has not developed criteria to guide this process. GAO found the Corps varies in the factors it uses to rank Section 219 projects. For example, one district considers whether a project can be completed within the fiscal year, while another considers the level of congressional support and dollar value of the project. Headquarters officials said the agency views Section 219 projects as outside its core mission areas and therefore has not developed written criteria. Congressional direction has indicated that the Corps is to consider characteristics—such as projects with the greater economic impact—in prioritizing Section 219 project funding. While aware of this direction, Corps officials said they do not consider it when ranking projects. Federal standards for internal control states that agencies should use quality information to achieve their objectives. By establishing written criteria, the Corps would have greater assurance that its Section 219 project selections align with a clear set of priorities, such as those identified by recent congressional direction. GAO recommends that the Corps develop written criteria for ranking Section 219 projects for funding, taking into account a clear set of priorities, such as those identified by recent congressional direction. The agency concurred with the recommendation.
