Discussion Framework for Development of a Draft Water Reuse Action Plan 4/18/2019 Discussion Framework for Development of a Draft Water Reuse Action Plan A Collaborative Call for Action: Development of a Water Reuse Action Plan On February 27, 2019, at a water reuse summit in San Francisco, the U.S. Environmental Protection Agency (EPA) announced the development of a Water Reuse Action Plan that will better integrate federal policy and leverage the expertise of both industry and government to ensure the effective use of the Nation's water resources. The EPA is bringing together experts across the water sector to identify a path forward that will provide more water to users while protecting human health and the environment. "The Nation's water resources are the lifeblood of our communities, and the federal government has the responsibility to ensure all Americans have access to reliable sources of clean and safe water/' said David Ross, U.S. EPA's Assistant Administrator for Water. "There is innovative work happening across the water sector to advance water reuse, and the EPA wants to accelerate that work through coordinated federal leadership." A draft of the plan is scheduled for release and public review in September 2019 at the Annual WateReuse Symposium in San Diego. This Discussion Framework is intended to frame the context for, and inform the development of, a Water Reuse Action Plan. I. Vision Water reuse can be a valuable means to enhance the availability and effective use of our Nation's water resources and should be considered as part of an integrated water resources management approach to meet the future needs of our Nation. An integrated approach commonly involves a combination of water management strategies (e.g., water supply development, water storage, stormwater management, water use efficiency, and water reuse) and engages multiple stakeholders and needs. The EPA, in collaboration with the Department of Interior, Department of Agriculture, the Department of Energy and other federal agencies, states, tribes, locales, the water sector, and other partners and stakeholders, will work to enhance consideration and application of water reuse through development and implementation of a Water Reuse Action Plan (WRAP). For purposes of this discussion framework, "water reuse" includes other common terminology including recycled water, reclaimed water, alternative water supplies, improved water reliability, and water resource recovery. The EPA will leverage and continue to engage with other federal agencies, states, tribes, local governments, water utilities, industry, agriculture, and others with keen water interests. The EPA will also be a key partner to implement the Water Security Grand Challenge with the U.S. Department of Energy, which has elements related to water reuse: "The Water Security Grand Challenge will incentivize new technologies aimed at solving one of the most important global challenges of our time - providing access to clean, safe, and secure water. EPA looks forward to partnering with DOE to help bring clean and safe water to communities across the country and find innovative ways to transform non-traditional water sources into resources." — EPA Administrator Andrew Wheeler, October 25, 2018 II. Business Case - Impetus for Action The Nation's water resources are the lifeblood of our communities, supporting our economy and way of life. Across the country, we depend upon reliable sources of clean and safe water.1 Though water reuse is a well-established practice in certain areas, substantial opportunities exist to optimize its consideration and application for many different purposes across the country. For example, forty out of fifty state water managers expect to face freshwater shortages in their states in the next ten years.2 1 EPA Strategic Plan, FY 2018-2022, February 12, 2018 2 Government Accountability Office (GAO) 2014. Freshwater: Supply Concerns Continue and Uncertainties Complicate Planning. GAO-14-43 1 ------- Discussion Framework for Development of a Draft Water Reuse Action Plan 4/18/2019 Multiple federal and state agencies maintain initiatives that address water reuse (see Sections IV and VI), but improvements in coordination or leveraging could maximize benefits and progress could be accelerated with an integrated, crosscutting strategy and action plan. Congress, multiple states, and stakeholders have increasingly called for action and focus on water reuse, which could be bolstered by federal, state, and watershed-based collaboration, when desired and appropriate. The literature identifies many motivations for consideration of water reuse as part of a diverse portfolio of water sources to meet current and future water demands, including: Widespread adoption of coordinated and integrated water resources management; Creating water alternatives in response to prolonged and severe droughts; Accommodating population growth and urbanization; Substituting reclaimed water for applications that do not require drinking-quality water; Protecting aquatic ecosystems through targeted restoration and avoided withdrawals/diversions; Addressing groundwater overdrafts and related impacts (land subsidence, saltwater intrusion, etc.); Lowering energy costs for treatment and transportation of water; Enhancing water security through portfolio diversification and resilience; and Augmenting existing water sources to enable long term economic and environmental sustainability. III. Use Cases - Possible Examples of Types and Fit-for-Purpose Applications of Water Reuse Table 1 identifies some broad categories of potential water reuse applications. The information in the table is not exhaustive. The table is followed by brief illustrative examples of current water reuse practices that help to demonstrate applications and opportunities for fuller consideration of water reuse. Table 1. Example water reuse categories, applications, and implementation challenges.

Indications of use of wastewater for agricultural irrigation extends back about 3000 years to ancient Greece.3 In 1929 the City of Pomona, CA, initiated use of reclaimed water for lawn and garden irrigation.3 By 2002, nearly half of all reclaimed water produced in California was used for agricultural irrigation.3 The Monterey Regional Water Pollution Control Facility began delivering 20 million gallons per day (mgd) of recycled water for food crop irrigation in 1998,4 and today, Monterey One Water recycles around four billion gallons a year for crop irrigation.5 The Transforming Drainage project across the upper Midwest is exploring the connection of agricultural drainage water management and irrigation. Direct Potable Reuse (DPR) - The first demonstrated practice of DPR began in Namibia in 1968 and continues today.3 The first DPR in the U.S. may have taken place in Chanute, KS, in 1956-1957 when the Neosho River ceased to flow; Chanute reused its treated sewage for five months, recirculating it some eight to fifteen times.3 In 2013, Wichita Falls and Big Spring, TX, both spurred by drought, received approval from the Texas Commission on Environmental Quality to implement DPR programs.4 El Paso, TX, launched a pilot facility in 2015 to create water suitable for DPR; its future full-scale facility will produce 10 mgd, helping to serve 36,000 homes.6 Currently, several states are exploring or developing frameworks for DPR. Indirect Potable Reuse (IPR) - The Upper Occoquan Sewage Authority (UOSA) in Northern Virginia is a commonly cited example of a planned IPR. UOSA's advanced water reclamation facility, operating since 1978, discharges about 50 mgd to the Occoquan Reservoir, used as a source for drinking water. The reclaimed water represents as little as 10 percent or as much as 90 percent of the reservoir inflow, depending on rainfall conditions.3 While UOSA is an example of planned IPR, unplanned or "de facto" IPR is very common across the U.S.4 Onsite Non-potable Reuse - The Alaska Water and Sewer Challenge is spearheading research and development of decentralized systems that enable reuse in rural households, to cost-effectively protect public health and manage water resources while improving affordable access to clean and safe water.7 In New York City, eight Battery Park City buildings that utilize onsite non-potable reuse consume 50 percent less water and discharge 60 percent less wastewater than similarly-sized buildings in NYC.8 Groundwater Recharge - In California, Orange County Water District (OCWD) began groundwater injection of reclaimed water in 1975. Today, OCWD injects 100 mgd into the aquifer to replenish water production wells and prevent saltwater intrusion.4 Industrial Reuse-Opportunities for reuse include cooling water, boiler water, process, water, and other needs. In 1995, 0.4 percent of U.S. manufacturing water needs were met with reclaimed water while 60 percent came from surface water and 17 percent from public water supplies.3 Bethlehem Steel Company in Baltimore, MD, used chlorinated wastewater effluent for steel processing from 1942 through the 1990s.3 West Basin Water District (Los Angeles, CA) produces water fit for specific needs of various types of customers (e.g., cooling tower and boiler feed water, irrigation).3 3 Metcalf & Eddy. 2007.

Environmental Restoration- Phoenix, AZ, uses treated wastewater to restore and maintain 500 acres of vital wetland and riparian habitat in the Salt River bottomlands.4 IV. Examples of Efforts Potentially Related to a Water Reuse Action Plan Federal - Presidential Memo: Promoting the Reliable Supply and Delivery of Water in the West (10/19/18) "directs for federal investment in technology and reduction of regulatory burdens to enable broader scale use of recycled water; and programs that promote and encourage innovation, R&D of technology that improve water management, using best available science through real-time monitoring of wildlife and water deliveries." - Water Security Grand Challenge announced by Secretary of Energy Perry (10/25/18) has at least two challenge goals that specifically involve opportunities for water reuse: energy produced water and municipal wastewater. - Water Infrastructure Improvements for the Nation Act (Public Law 114-322) (WIIN) amended the Water Infrastructure Finance and Innovation Act (WIFIA) to include explicit eligibility for "a water recycling project or a project to provide alternative water supplies to reduce aquifer depletion" (Section 5008 of WIIN). Integrated Planning was also codified as a component of Clean Water Act implementation in 2019. - America's Water Infrastructure Act of 2018 specifies Congress' intent that water reuse is a key part of the national water infrastructure: o S.2004 - Sense of Congress that nonpotable sources for industry can relieve supply/demand challenges. Encourages implementing and incentivizing nonpotable reuse to achieve water savings and conservation needs, o S.2007- Authorizes $10m in FY19/20; requires new grant program to accelerate research and development and technology deployment. o S.2017- Requires the EPA to comprehensively review drinking water treatment technologies and disseminate results, o S.4102 - Requires the EPA to disseminate information on cost-effective and alternative technologies, and Report to Congress within one year, and tri-annually thereafter, on alternative wastewater treatment and recycling tech. - Federal Technology Transfer Authority (15 (JSC 3710a) and Federal Prize Competition Authority (15 (JSC 3719) authorizes federal agencies to collaborate on research and development and related efforts. - National Drought Resilience Partnership (NDRP), established by Presidential Memorandum (2016), coordinates efforts among agencies to assist in building long-term drought resilience in basins and regions. - U.S. Government Global Water Strategy (2017) outlines the Federal Family's global approach to fostering a water- secure world, describing each Agency's roles therein, such as Bureau of Reclamation's charge to foster water reuse and recycling. U.S. EPA - EPA Reuse Guidelines (5): 2017 Potable Reuse Compendium and Guidelines for Water Reuse (2012, 2004, 1992 and 1980). - Office of Water Study of Oil and Gas Extraction Wastewater Management to solicit perspectives on, and consider management approaches, in unconventional and conventional oil and gas wastewater management. - Office of Water Microbial Risk Assessments related to Potable Reuse (see "Nappier et al." in Section X). - EPA-New Mexico Memorandum of Understanding to clarify existing regulatory and permitting frameworks related to the way produced water from oil and gas extraction activities can be reused, recycled, and renewed for other purposes. The EPA and New Mexico developed a draft white paper, "Oil and Natural Gas Produced Water Governance in the State of New Mexico," released November 9, 2018. V. Potential Areas of Focus Over the past several years, a range of federal and non-federal activities have been carried out to characterize the potential for water reuse in different sectors or subsectors of the economy. For example, in 2018, the Water Environment Federation released a Water Reuse Roadmap and the report Mainstreaming Potable Water Reuse in the United States, was published by ReNUWIt, Johnson Foundation, and the EPA. Other federal agencies and 4 ------- Discussion Framework for Development of a Draft Water Reuse Action Plan 4/18/2019 organizations have developed similar works. The WRAP will not attempt to repeat these recent efforts but will draw on their findings and recommendations to determine what knowledge gaps or actions need to occur to bolster opportunities for water reuse across all sectors of the U.S. economy. International examples and models will also be used, as appropriate, to determine if they would also serve as solutions in the U.S. Components of a WRAP may include the actions of many water stakeholders and address several thematic areas frequently identified in the literature, including: 1) technological improvements, 2) regulatory/policy aspects, 3) financial initiatives; 4) performance metrics, 5) water information use and availability, and 6) public outreach. Each type of reuse could be evaluated against these six components to provide a greater understanding of the incentives for and barriers to water reuse. Below are some examples of high-level actions and/or information gaps under each of the six components. In facilitating development of the WRAP, the EPA will engage stakeholders and brainstorm action items and specific activities related to water reuse. Actions identified for consideration in the WRAP could be taken by a variety of different water stakeholders or groups with collaborative interests. 1. Technological Improvements a. Technology Development. Piloting. Validation - Identifying technological needs and validation requirements; evaluating applications, efficacy, and limitations of existing technologies; and fostering opportunities for onsite and mobile pilot testing to assist regulators and drive costs and feasibility towards "pipe parity" (e.g., closer or equal to other water supplies). b. Monitoring and Sensors - Collecting timely, robust, quality data (constituents and surrogates) to (a) verify that water is safe and meets quality expectations, namely online and offline standardized methods to understand reuse water needs and fit for purpose baselines (for example, biological risks and operations for potable reuse; dissolved mineral content for niche manufacturing; or optimizing stormwater management and capture with real-time weather information); and (b) ensure systems operate as designed (e.g., component performance, protection of downstream components). c. Concentrate and Brine Management - Determining the management and reclamation opportunities for managing brines/concentrates, with specific focus on areas facing limited viable and environmentally acceptable disposal methods. d. Research Coordination and Critical Science Gaps - Building upon decades of research across the Federal and private sector to close any remaining critical gaps. e. International Experience- Building upon the extensive technology and reuse practices of the international community (e.g., Israel, Namibia, Singapore, Australia). 2. Regulatorv/Policv Aspects at All Levels of Government a. Public Health Protection - Exploring establishment of public health benchmarks and guidelines, and risk-based baselines (e.g., pathogen removal targets and other risk-based constituent removal targets), to advance the practice - particularly in types of reuse which lack guidelines/regulatory frameworks - and continuing development and utilization of tools and processes for locales and water managers to evaluate public health risks and ensure any reused water is fit for purpose. b. Regulatory and Policy Incentives. Challenges. Barriers, and Facilitation - Creating an environment where reuse can be realistically and routinely considered within a unified framework. c. Source Control - Building on existing programs and capabilities such as using local Pretreatment Programs to apply source tracking and control to help protect the quality of recycled municipal wastewater. 5 ------- Discussion Framework for Development of a Draft Water Reuse Action Plan 4/18/2019 d. Workforce and Operator Training Certification Programs - Fostering a workforce with training and skills to operate complex technologies, and manuals of practice and procurement to support operators and administrators alike. e. Addressing Other Regulatory or Institutional Barriers - Considering expanded alternatives for the management and disposal of wastewaters, such as oil and gas produced water, that in turn spur technology development. 3. Financing a. Financing and Funding Eligibility - Providing additional funding opportunities and incentives; and ensuring federal and state funding eligibility is clear and can be easily integrated with other funding programs. b. Affordability - Bolstering water reuse's ability to lower the total cost of water, as one of many tools to address burgeoning household water affordability issues around the country. 4. Fit for Purpose a. Water Quality Performance Metrics to Assure that Recycled Water Meets Use and User Needs - Helping states and other entities determine frameworks and scale-specific levels of treatment for recycled water depending on intended use (i.e., including potable; ecosystems; groundwater; irrigation/agriculture; boiler/cooling water; etc.) and technical and/or infrastructure specifications. b. Transform the Design and Implementation of Agricultural Drainage - Helping states and landowners understand the potential benefits of storing water in the landscape and implement various forward- looking drainage practices to support resilient and productive agricultural systems and improve downstream water quality. c. Maximizing Opportunities for Environmental Restoration - Understanding water quality-based capabilities for targeted environmental restoration, such as reducing secondary and/or combined stormwater discharges while improving streamflow and habitat in impaired watersheds. d. Identifying Frameworks - Identifying frameworks and design scale ranges for which metrics and standards are needed, desired, and applicable. 5. Information about Water Use and Availability a. Data Sharing. Integration and Exchange - Creating the mechanisms for water quality and quantity information to be shared and integrated and usable at the different scales to facilitate integrated water resources management, including water reuse opportunities. This sharing and integrating of water information is often referred to as the "Internet of Water".9 b. Data Governance - Encouraging watershed-based water information hubs and collaboratives to optimize sharing and integration of information to improve integrated water management. 6. Outreach Opportunities a. Public Outreach - Understanding the importance of public acceptance of reused water, and ensuring clear, consistent messaging and risk communication from federal agencies on basic questions related to reuse. Articulating lessons learned. More messaging on a national level of the benefits of reuse and the appropriate and applicable public health and environmental safeguards. b. Public Education - Using best-practices in risk communication to help the public understand the level of protection and risk associated with current programs and requirements. c. Communication - Facilitating the deployment and dissemination of critical and relevant water reuse-related information and templates for information delivery. d. Reuse Case Examples - Identifying successful projects to provide insights on opportunities and barriers to water reuse. 9 Aspen Institute. 2017.
