Rural communities often have small or aging drinking water and wastewater systems. The need for a water project can arise for multiple reasons, including replacing or upgrading outdated or aging equipment that does not treat water to meet water quality standards and systems that do not produce water to meet new treatment standards. For example, arsenic is often present naturally in groundwater, and to meet new federal arsenic standards for drinking water, many rural communities using groundwater as a drinking water source will have to improve their drinking water systems to remove arsenic. EPA estimates that drinking water and wastewater infrastructure for small communities over the next several decades could cost more than $100 billion. This section describes (1) federal funding for drinking water and wastewater infrastructure projects in rural communities; (2) the process for applying for these federal funds, including the requirements state and federal agencies must ensure rural communities meet under the National Environmental Policy Act; and (3) our prior work on coordination among federal agencies and rural water infrastructure programs. The federal government administers a number of programs that assist rural communities in developing water and wastewater systems and complying with federal regulations, with EPA’s drinking water and clean water SRF programs and USDA’s RUS program providing the most funding. Communities typically pay for drinking water and wastewater infrastructure through the rates charged to users of the drinking water and wastewater systems. Large communities serve many people and can spread the cost of infrastructure projects over these numerous users, which makes projects more affordable. Small or rural communities have fewer users across which to spread rate increases, making infrastructure projects less affordable and these communities more reliant on federal funding to help lower the cost of projects through lower interest rates or grants that do not need to be repaid. The Safe Drinking Water Act and the Clean Water Act authorize the Drinking Water SRF and Clean Water SRF programs, respectively, as well as EPA’s authority to regulate the quality of drinking water provided by community water supply systems and the discharge of pollutants into the nation’s waters. Under the Safe Drinking Water Act, EPA sets standards to protect the nation’s drinking water from contaminants, such as lead and arsenic. In 1996, amendments to the act established the drinking water SRF program to provide assistance for publicly and privately owned drinking water systems. Under the Drinking Water SRF program, states make loans and are required to provide a certain percentage of funding in loan assistance to communities of less than 10,000. The Clean Water Act is intended to maintain and restore the physical, chemical, and biological integrity of our surface waters, such as rivers, lakes, and coastal waters. In 1987, amendments to the Clean Water Act established the Clean Water SRF program to provide assistance to publicly owned wastewater treatment facilities. Using the federal funds EPA provides to capitalize the state SRF programs, states provide loans to communities for drinking water and wastewater treatment projects. In order to qualify, states must contribute an amount equal to 20 percent of the federal capitalization grant. States that qualify for funding are responsible for administering their individual SRF programs, and communities of any size can apply for assistance. Loans are generally provided at below-market interest rates, saving communities money on interest over the long term. As communities repay the loans, the states’ funds are replenished, enabling them to make loans to other eligible drinking water and wastewater projects, and creating a continuing source of assistance for communities. See figure 1 for a description of the state Drinking Water and Clean Water SRF program funding sources. Nationwide, there are almost 52,000 publicly and privately owned drinking water systems and 16,000 publicly owned wastewater treatment facilities. USDA’s RUS administers a water and wastewater loan and grant program for rural communities with populations of 10,000 or less. The program is designed to address public health concerns in the nation’s rural areas by providing funding for new and improved drinking water and wastewater infrastructure. RUS provides a mix of loan and grant funding to communities that have been denied credit through normal commercial channels. Like the SRF programs, the RUS program makes loans at below-market rates to save communities interest over time but, unlike the SRF programs, the RUS program can make loans for up to 40 years, which helps lower communities’ annual repayment costs. In addition, communities do not need to repay funds received as grants, further helping to reduce the overall financial burden they incur upon a water project’s completion. To determine the amount of loans and grants a community receives, RUS assesses the potential increase in the water or sewer user rate needed to repay the loan. RUS provides grants to communities when necessary to reduce user rates to a level that the agency determines to be reasonable. Other federal agencies have programs that provide funds for drinking water and wastewater infrastructure, including HUD’s Community Development Block Grant program and the Department of Commerce’s Economic Development Administration’s Public Works and Economic Development Program. Under HUD’s program, communities use block grants for a broad range of activities to provide suitable housing in a safe living environment, including water and wastewater infrastructure. Thirty percent of block grant funds are allocated by formula to states for distribution to communities of 50,000 or less. Drinking water and wastewater needs compete with other public activities for funding and, according to HUD officials, account for about 10 percent of all block grant funds nationally. Economic Development Administration’s Public Works and Economic Development Program provides grants to small and disadvantaged communities to construct public facilities, including drinking water and wastewater infrastructure, to alleviate unemployment and underemployment in economically distressed areas. In addition, the U.S. Army Corp of Engineers and the Department of the Interior’s Bureau of Reclamation provide financial assistance for some large drinking water and wastewater projects, but these projects must be authorized by Congress prior to construction. In addition to these federal programs, some states have created their own programs to provide assistance for drinking water and wastewater infrastructure. For example, the North Carolina Rural Economic Development Center provides infrastructure loans for communities in the state’s rural counties. In Montana, the Treasure State Endowment Program provides grants to make drinking water and wastewater projects more affordable for the state’s communities. The state SRF programs and the RUS program each have their own application process through which communities can apply for funding, although the application processes generally include similar steps: (1) completing an application that asks for, among other things, basic demographic, legal, and financial information associated with the project; (2) developing a preliminary engineering report that provides basic design specifications and other technical information for the project; and (3) conducting an environmental analysis that considers the environmental effects of the proposed project and alternatives. The state agencies responsible for EPA’s SRF programs and USDA state offices review these documents, prioritize the projects based on agency-determined criteria, provide comments to communities on how their applications can be improved, and ultimately approve or reject the request for funding. Communities can choose to apply for funding to different federal and state programs at any stage during the process. In some cases, the SRF and RUS programs will work together to jointly fund the same project if the project is too large for one agency to fund, or if it will make the project more affordable for the community. If their requests are approved, communities design the projects, obtain construction bids, contract to build the projects, and are reimbursed by the funding agency. Communities usually hire a consulting engineer to develop the preliminary engineering reports and conduct the environmental analyses for a project. In addition, EPA and USDA pay for technical service providers that communities can use to help them understand and apply for their programs. Communities can also get assistance from local planning districts, which are voluntary associations of county and municipal governments that provide development assistance to their membership. A preliminary engineering report describes the proposed project, including its purpose, features of the proposed location, condition of any existing facilities, alternative approaches considered, design features, and costs. Figure 2 shows the application process and timeline that is generally followed for both EPA and RUS programs. The state SRF and RUS state-level programs review the likely environmental effects of projects they are considering funding using different levels of environmental analysis. These reviews occur either under the National Environmental Policy Act of 1969 (NEPA) for the RUS program, or for the SRF programs, under a state environmental review process similar to NEPA. EPA regulations define the necessary elements of these state “NEPA-like” reviews. Typically, a proposed water or wastewater project is subject to an environmental assessment or, in the rare case that the project is likely to significantly affect the environment, a more detailed environmental impact statement. If, however, the agency determines that activities of a proposed project fall within a category of activities the agency has determined has no significant environmental impact—a determination called a categorical exclusion—then the project applicant or the agency, as appropriate, generally does not have to prepare an environmental assessment or environmental impact statement. Because many community water and wastewater infrastructure projects either upgrade or replace existing infrastructure, projects rarely result in significant environmental impacts, and NEPA requirements can be satisfied through an environmental assessment or a categorical exclusion. In addition, in some cases, the funding agency may help complete the environmental analysis documents for a planned project. Our previous work has raised questions regarding sufficient coordination between drinking water and wastewater infrastructure funding programs, despite federal efforts to improve coordination at the state and local level. In December 2009, we reported that EPA, USDA, and other agencies that fund drinking water and wastewater infrastructure for rural communities along the U.S.-Mexico border, lacked coordinated policies and processes and did not efficiently coordinate their programs, priorities, or funding. Specifically, without efficient coordination, applicants faced significant administrative burdens that, in some cases, resulted in project delays because the programs required separate documentation to meet the same requirements and did not consistently coordinate in selecting projects.
