&EPA United States Environmental Protection Agency Land Research Program Multi-Year Plan: Fiscal Years 2007-2012 U.S. Environmental Protection Agency Office of Research and Development Washington, DC 20460 Final Report, July 2007 ------- Administrative Note The Office of Research and Development's (ORD) Multi-Year Plans (MYPs) describe what research ORD proposes to accomplish over the next 5-10 years in a variety of areas. The MYPs serve three principal purposes: to describe where the research programs are going, to present the significant outputs of the research, and to communicate the research plans within ORD and with stakeholders and clients. Multi-year planning permits ORD to consider the strategic directions of the Agency and how research can evolve to best contribute to the Agency's mission of protecting health and the environment. MYPs are intended to be "living documents." ORD will update MYPs on a regular basis to reflect the current state of the science, resource availability, and Agency priorities. This MYP was internally reviewed by ORD's Science Council in November 2005. The Land MYP was externally peer reviewed by the Board of Scientific Counselors (BOSC) Land Subcommittee in December 2005, and a formal response to comments was provided to the BOSC Executive Committee in 2006.

This approach promotes ORD's focus on the highest priority issues and provides a roadmap to achieving our long-term research goals. The purpose of the multi-year plans (MYPs) is to provide a framework integrating research across ORD's Laboratories and Centers and Government Performance and Results Act (GPRA) goals in support of the Agency's mission to protect human health and to safeguard the natural environment. MYPs are composed of three major components: (1) a narrative description of the plan; (2) a wiring diagram outlining the sequence and relationship of annual performance goals (APGs) needed to achieve each long-term goal (LTG); and (3) a matrix of goals and measures (APGs and associated annual performance measures [APMs]) needed to meet the LTGs identified in the plan. The MYP matrices align the outputs in a particular year with the APGs they support, even if the APG is in an out-year. These goals and measures are based on total annual resource levels for the topic area consistent with the resource level proposed in the most recent President's Budget. By helping to identify the impact of potential planning decisions, MYPs aid in the evaluation of research options and foster the integration of strategic, risk-based environmental protection and anticipation of future environmental issues. They also allow for a more comprehensive understanding of changes needed to emphasize a new direction or accelerate an existing program. MYPs are updated periodically to reflect changes in Agency strategic thinking, the realities of available resources, and the current state-of-the-science. The MYPs provide a link between the strategic plans and annual plans, showing how we intend to meet our out-year goals. MYPs also link the research strategies and research plans to show how ORD conducts research in an integrated fashion to reach major milestones and end points. The Land Research Program (LRP) MYP puts forward ORD's strategy for planning and conducting research in response to the following: Office of Solid Waste and Emergency Response (OSWER) and Regional priorities for the LRP, presented in Appendix A Authorizing legislation (e.g., Superfund Amendments and Reauthorization Act [SARA] 9660b; Resource Conservation and Recovery Act [RCRA]), discussed further in Appendix B Linkage to the EPA Strategic Plan, appropriate research areas under the Land Preservation and Restoration Goal (Appendix C) Board of Scientific Counselors (BOSC) and EPA Science Advisory Board (SAB) peer reviews (Appendix D) National Academy of Sciences (NAS) and other resource documents1 Documents that contributed to the development or revision of this plan include the following: EPA Strategic Plan, http://+www.epa.gov/ocfo/ . SAB Review of Contaminated Sites and RCRA MYPs, June 2005. BOSC Review of Land Research Program, December 2005. . NRC: A Risk Management Strategy for PCB-Contaminated Sediments, 2001, p. 5, Research Needs. ------- Office of Management (OMB) Program Processing Rating Tool (PART) evaluations and measures (Appendix F) ORD strategic decisions and initiatives. The LRP MYP is built upon two previous reports, the Contaminated Sites MYP and the RCRA MYP. The ORD Executive Council and the EPA SAB, in their review of these two plans, endorsed the combination of the plans and the development of an integrated research program. Approximate total research funding (FY07 PB) for EPA's Goal 3 Land program is $34.1 million; this funding supports extramural projects and 143 full-time employees (FTEs). Within Goal 3 there are four components, resource conservation (science and technology [S&T] appropriation) and three trust fund accounts: Superfund, Oil Spills, and Leaking Underground Storage Tanks (LUST CA). The trust funds can be used only to support research within the specific trust fund (e.g., oil spills). Figure 1 presents the funding and FTE levels for each of the four components of Goal 3. This plan is written on the assumption that the resources within each funding source will remain constant each year. Goal 3: Land Preservation and Restoration* Total Dollars: $34.1 and 142.8 S&T Appropriation Total Dollars: $10.6 M and 50.8 FTEs Superfund Appropriation Total Dollars: $22.0 M and 89.2 FTEs LUST Appropriation Total Dollars: $0.7M and 1.9 FTEs OIL Appropriation Total Dollars: $0.9M and 0.9 FTE Goal 4 HHRA Superfund Appropriation Total Dollars: $5.8 M and 7.0 FTEs Figure 1.

Preservation: The purpose of this research program is to provide improved scientific knowledge and develop and apply more cost-effective tools, models, and methods to manage material streams and inform land revitalization decisions. The Land MYP describes ORD problem-driven research as defined by the National Academy of Sciences (NAS, 1997), supporting the Office of Solid Waste and Emergency Response (OSWER) research needs and three OSWER trust fund programs for which research is authorized: Superfund (SF), LUST, and the Oil Spills Program. The Superfund research program is designed, in collaboration with OSWER and Regions, to address the most important science issues that affect policy development and program implementation. Because of limited resources, it is essential that our efforts are focused on the types of sites and problems that have higher risks, higher uncertainty, or higher impact in terms of number of sites, proximity to people, or value/size of ecological resources. The research program focuses on the important issues of contaminated sediments, ground water contaminant transport and remediation, and site characterization. The research program also provides site- specific technical support through topic-based centers and liaisons located in each region. Figure 2 outlines the variety of ways scientific support is provided by ORD to a site during site characterization and National Priorities Listing (NPL), remedial investigation/feasibility studies (RI/FS), communication to communities, and remedy selection. Related risk assessment research activities and technical support for the Superfund program are an important part of ORD support to OSWER. The Integrated Risk Information System (IRIS) and Provisional Peer-Reviewed Toxicity Values (PPRTV), as well as the production of risk assessments on major chemicals of concern, are important for OSWER guidance and regional risk assessment activities. These are addressed in a Human Health Risk Assessment (HHRA) MYP, discussed in Appendix E along with other related research. The oil spill and LUST CA research are small programs focused on client needs for tools, models, and methods to address oil spill prevention and remediation, and underground storage tank issues concerning chemical fate and transport (F&T). ------- OKD Support Site Cleanup Process Toxicity Data and InformaUon on Heavy Metals Site Assessment / NPL Determining Hydraulic Conductivity in Aquifer Sediment Transport Modeling RI/FS Evaluation of Ecological Effects National Remedy Review Board Community Involvement Support to Communities Technical Liaison Position to Enhance Region and QRD Interface Remedy Selection Figure 2. Example of a Summary of OKD Support at a Superfund Site (Reed et al., 2007) The preservation-oriented research program is transitioning to be responsive to program peer-review recommendations and broader OSWER strategic directions by addressing emerging issues in materials management and support of land revitalization decision processes. This change involves building on the foundation of the Multimedia, Multireceptor, Multipathway Risk Assessment (3MRA) program to support nanotechnology F&T research. We envision that EPA would be the Federal lead for nanomaterial environmental F&T research. Resources will support characterizing, modeling, and measuring the F&T of engineered nanomaterials in the environment, and analytical methods will be developed for detection and quantification of these nanomaterials. The exposure research will predict and evaluate unintended exposure pathways of engineered nanomaterials and evaluate and develop F&T mechanisms for nanomaterial release from intended pathways, such as zero-valent iron used for groundwater remediation. Additional material management research will support landfill bioreactors, landfill energy recovery, and technology transfer of cover/liner methods and debris management, which includes construction/demolition and disaster wastes. Reuse/Revitalization will focus on supporting Brownfields decision processes as well as bioavailability and teachability material reuse research. Within OSWER, principal clients of the research program include the Office of Superfund Remediation and Technology Innovation (OSRTI), Office of Solid Waste (OSW), Office of Emergency Management (OEM), Office of Underground Storage Tanks (OUST), and Office of Brownfields Cleanup and Redevelopment. Additional research clients include 4 ------- Regional and State staffs who implement these programs, regulated and responsible parties, and contractors who perform site-specific assessment and remediation. Peer Reviews and Evaluations In the past 3 years, the LRP has undergone two external peer reviews and an evaluation by the Office of Management and Budget (OMB). The EPA SAB conducted an advisory of the Contaminated Sites and RCRA MYPs in July 2004. The following quote is from the SAB letter to the Administrator on the findings of the panel: "In general, the Panel finds that the Contaminated Sites and RCRA Multi-Year Plans are programmatically and scientifically sound. We note in particular the remarkable coordination of the program's research with that of the relevant program offices and other institutions and are encouraged by the judicious use of leveraging opportunities to significantly stretch limited resources to meet more of the Agency's needs." The LRP and the draft Land MYP were externally peer reviewed by the ORD BOSC in December 2005. The panel had positive comments on relevance, quality, and performance of program. In 2006, the LRP underwent an OMB Program Processing Rating Tool (PART) evaluation and received an adequate rating. Long-term, annual, and efficiency measures were established for the program under the PART process. The programmatic changes in response to peer-review and OMB comments are discussed in Section 5.1 and Appendices D and F. This MYP incorporates peer-review recommendations and presents a transparent planning process that incorporates regional research needs and priorities, and program office research needs and priorities and utilizes that information in the Land Research Coordination Teams (RCT) evaluation and prioritization process. LTGs are focused on research products utilized by our clients that lead to outcomes in support of OSWER programs. The plan also addresses OMB relevance, quality, and performance criteria in focusing on the program goals and documented performance measures of the problem-driven research program. Figure 3 shows a logic diagram5 that summarizes the features of the research program. The OSWER statement of research needs indicates areas within this framework where ORD should direct its efforts, and the Activities and Outputs columns in the diagram reflect the research themes of the program. OSWER and the Regions are identified as the primary clients and the short-term outcomes for the research program are client use of our products to support their activities in cleanup, corrective action, and material management. The client use of our research products is specified in the two long-term goals for this MYP. The regions, states, and their contractors are identified in intermediate outcomes to which our products and technical support are further applied to address site-specific issues. The environmental and long-term outcomes support the objectives of Goal 3 in the EPA Strategic Plan. McLaughlin, J.A., andG.B.

Logic Diagram of the Land Research Program 3.0 Progress to Date, 2002-2006 Key Accomplishments of the Land Program Restoration Long-Term Goal Contaminated Sediments Enhanced F&T modeling was incorporated at three major sediment sites. Evaluation of sediment resuspension models showed that they generally over-estimate the release and bioaccumulation of persistent organic contaminants from sediments after dredging operations. Key data were identified to improve the models. Combined use of field data and bioaccumulation models was demonstrated in a hybrid approach to extrapolate accumulation of persistent contaminants found in sediments. These findings improve ecological risk assessment of contaminated sediments. Bauxite has been found to be capable of sequestering a broad variety of heavy metals, including Hg, As, Cr, Cd, Pb, Zn, and Ni. Due to its unique surface properties, bauxite is ------- able to sequester both cationic and oxy-anionic forms of the metals through a combination of adsorption, absorption, ion exchange, and precipitation. Bauxite can be installed as a much thinner cap over the contaminated sediments, a critical parameter for remedy selection in navigable waters. Field evaluations of the performance of monitored natural remediation (MNR) and both sand and innovative caps will continue, with the aim of quantifying contaminant transport mechanisms to facilitate the prediction of remedy performance. Innovation in capping, both amendments and construction techniques (e.g., mats), will continue to be investigated. Boston Harbor/Eagle Harbor/Wyckoff Superfund Site. ORD is investigating the migration of contaminants through a sand cap and resuspension during cap placement to identify potential field methods for minimizing sediment resuspension during cap placement. The research indicated that resuspension can be minimized by using improved release techniques that result in fewer disturbances of the contaminated sediments. Ground Water Results of the permeable reactive barriers (PRBs) long-term performance study were recently published in a synthesis of research findings, "Capstone Report on the Application, Monitoring, and Performance of Permeable Reactive Barriers for Ground Water Remediation" (EPA/600/R-03/045). This report represents a synthesis of 10 years of research and development on PRBs. PRB technology has expanded rapidly in its use and acceptance as a viable approach for achieving site cleanup and closure. Over 100 applications of the technology are documented in the U.S. and worldwide. The primary reason for this expansion is that technology results in cost savings over other alternative methods. For example, use of PRBs over traditional pump & treat methods results in an operation & maintenance savings at two sites of $12 million. Research products on monitored natural attenuation (MNA) of metals were applied to the Region 1 Industriplex site to treat arsenic contamination and resulted in a remedial decision that saved more than $10 million and earned a regional award in 2006. ORD developed and tested a patented technology for treating ground water contaminated with Chrome VI in situ. Region 4 estimates the technology saved them over $1 million in remediation costs relative to initial estimates for cleanup. Multimedia ORD oil spills research supported the implementation of 40 CFR, Subchapter J, Part 300 -National Oil and Hazardous Substances Pollution Contingency Plan, Sub-Part J - Use of Dispersants and Other Chemicals. Modeling tools to support oil spills: http://www.epa.gov/athens/onsite/ Method 8261: Method/instrument developed, patented, and commercialized by ORD to support Superfund's need for robust methods to address problematic matrices. Vacuum ------- distillation was pioneered as an analytical technique for determining volatile organic contaminants (VOCs) in environmental/biological samples (two patents awarded for the vacuum distillation apparatus). One of the first true performance-based methods developed for RCRA SW-846 was Method 8261: a vacuum distillation/gas chromatography & mass spectrometry (GC/MS) method, using optimized quality control, and used for the analysis of all environmental/hazardous waste matrices, except that for air. Method 5032: use of vacuum distillation as an extraction technique (FY04 APM 209); "Interlaboratory Study Evaluating Vacuum Distillation VOC Analysis Technology (SW- 846 Method 8261) for Superfund Application." Analytical support to OSRTI, either through direct requests or via the Las Vegas Technical Support Center or other centers. This support includes analysis of extracts, data generated by various state-of-the-art analytical techniques (i.e., high-resolution mass spectrometry), and consultation on technical questions as requested from the Regions, States, Tribes, or Superfund Program Office. Preservation Long-Term Goal The risk from arsenic-bearing water treatment sludge residuals leaching from municipal landfills was shown by 3MRA to be minimal, potentially saving several million dollars per landfill. Technology transfer: Eight evapotranspiration covers for landfills under construction in 2006 are expected to save more than $30 million. Research and technology transfer on evapotranspiration covers for landfills has resulted in construction of the innovative cover at more than 35 sites. For 13 of the sites that reported figures (FY06 data), cost savings ranged from $20,000 to $100,000 per acre, with a median savings of $40,000, compared to a conventional multi-layer cover. More than 2,500 people have attended classroom or internet training, much of it leveraged through the Interstate Technology & Regulatory Council, a state-federal partnership for state regulators. Bioreactor research won a Kentucky Governor's Award in 2003 and a SWANA Landfill Management award in 2005. Brownfields Tools: SMARTe contains four primary components: Screening Tool- leads users through the entire revitalization process eDocument - provides information, links, and resources regarding the revitalization process Search engine - allows users to search for information, tools, and best practices Toolbox - contains electronic tools (e.g., searchable databases, templates, calculators) to analyze and solve revitalization issues. http://www.epa.gov/brownfields/tools/tti_smarte.htm ------- 4.0 Current Priorities of OSWER and Associated Research Issues Four themes characterize OSWER's land program activities under Goal 3: The One Cleanup Program; Recycling, Waste Minimization, and Energy Recovery; Revitalization; and Homeland Security. One Cleanup Program: Through the One Cleanup Program, OSWER is looking across its programs to bring consistency and enhanced effectiveness to site cleanups. The Agency is working with its partners and stakeholders to enhance coordination, planning, and communication across the full range of Federal, State, Tribal, and local cleanup programs. This effort is intended to improve the pace, efficiency, and effectiveness of site cleanups as well as more fully integrating land reuse and continued use into cleanup programs. OSWER is developing environmental outcome performance measures that report progress among all cleanup programs. Recycling, Waste Minimization, and Energy Recovery (Objective 3.1 Preserve Land): OSWER's strategy for reducing waste generation and increasing recycling is based on the following: (1) establishing and expanding partnerships with businesses, industries, States, communities, and consumers; (2) stimulating infrastructure development, environmentally responsible behavior by product manufacturers, users, and disposers ("product stewardship"), and new technologies; and (3) helping businesses, government, institutions, and consumers by education, outreach, training, and technical assistance. Revitalization: OSWER and its partners are restoring contaminated land to make it economically productive or available as green space. Like the Brownfields program included under Goal 4, these revitalization efforts complement OSWER's traditional cleanup programs under Sub-objective 3.2.2 and enable affected communities to reuse contaminated lands in beneficial ways. OSWER is developing performance measures to assess its success in restoring and revitalizing sites under all its cleanup programs. Emergency Preparedness, Response, and Homeland Security (Sub-objective 3.2.1): OSWER has a major role in reducing the risk to human health and the environment posed by accidental or intentional releases of harmful substances and oil. OSWER is working to improve its capability to effectively respond to these incidents, working closely with other federal agencies within the National Response System. OSWER relies upon its 10 Regions, in partnership with States and Tribes, to implement these program priorities nationally. Through their work, the Regions and their partners enable communities to reuse contaminated land, effectively clean up contaminated sites, reduce waste generation and increase recycling, and reduce risk by responding to releases of harmful substances and oil. ------- 4.1 OSWER and Regional Research Needs OSWER identified its research needs through an iterative process, beginning with a review by Office of Science Policy staff of previously developed needs lists. During this review, needs that had already been met by ORD or other offices were deleted, and new needs were added. To this revised list were added OSWER-related needs suggested by the EPA Regional Science Council and EPA Regional staff in both the Superfund and RCRA Corrective Action programs. OSWER added to its master list additional needs relayed from Regional Division Directors, Branch Chiefs, Technical Support Section Chiefs, and Technical Support Project members during a review of potential research projects being considered for funding under a proposed FY06 research project program. This compiled list of research needs was then combined and cross referenced with the ORD current research program for further prioritization and evaluation. The resulting tables are presented in Appendix A. In 2005, OSWER formed five Regional Research Advisory Workgroups (RRAWG) to help develop and prioritize research needs as well as perform other coordinating functions between ORD and the Regions related to site cleanup. These workgroups consist of Regional and OSRTI staff, with liaisons from ORD's Hazardous Substance Technical Liaisons in the Regions and ORD staff from the Laboratories and Centers. The workgroups are discussed in the following section. 4.2 Description of Process to Prioritize and Address Research Needs Needs for Superfund-Oriented Research As part of the process in combining the RCRA and Contaminated Sites MYPs, the Land RCT wanted an improved method to incorporate Regional scientists into the research planning process and to document responsiveness in the research program to Regional input. The Regional and OSWER representatives on the RCT identified research planning workgroup topics and recruited experts from various regional technical groups, such as the Engineering Forum, the Ground Water Forum, members of the Risk Assessment Teleconference for Superfund, Ecological Risk Assessment Forum, and Sediments workgroups to serve in these research planning workgroups. The workgroups were asked to become The general duties for these advisory workgroups: Form a basic understanding of current ORD research in the above areas (from summary presentations from ORD via conference call, lab visits, etc.). Advise Land RCT of regional needs in their area and priorities in OSWER's list of research needs. Provide feedback on ORD products in the above areas. Advise Land RCT about specific projects that they see as high and low priorities among items in the MYP. Read quarterly reports from the ORD Technical Support Center in the above areas and provide feedback on their functioning when needed. The time commitment for these advisory teams will be 1-2 years, with an approximate time commitment of 4-8 hours per month. 10 ------- familiar with the current research program and the associated research products, and to evaluate the research program activities and the list of research needs that have been identified by the Program Office and the Regions. The workgroup utilized a set of criteria and rankings so that a documented process was produced. The primary task for the advisory workgroups was to review the research needs and current research program (Appendix A) under their topic (e.g., contaminated sediments) and rank them (high, medium, or low). Ranking criteria for each activity/need: Feasibility and timeliness: Is investing in this now likely to meet the need? Applicability across sites/assessments: Would meeting the need impact a large number of sites or a high-priority risk pathway, or reduce cost/response time? Importance to several regions or programs: Is the need important to multiple Superfund Regions and/or RCRA, Water, Air, or Toxics? There are five advisory workgroups: 1. Sediment: ecological effects, modeling, sampling, monitoring, and remedy-specific research; Superfund Sediment Resource Center; Ecological Risk Assessment Center. 2. Ground Water: MNA, dense non-aqueous phase liquid (DNAPL), and vapor intrusion (VI) research; Ground Water Technical Support Center. 3. Engineering, Containment, and Soil Treatment: soil containment and treatment; landfill covers, gas, and liners; Engineering Technical Support Center. 4. Site Characterization and Methods: sampling techniques, analysis methods, and statistics; Monitoring and Site Characterization Technical Support Center; Environmental Photographic Interpretation Center. 5. Human Health Risk Assessment: all research conducted through the National Center for Environmental Assessment (NCEA). The RCT criteria: Feasibility and timeliness: Is investing in this now likely to meet the need? Importance to Regions Importance to OSRTI Responsiveness to BOSC and SAB recommendations Ability and expertise of ORD to do the research Is it a strategic direction for ORD and the research program? Are any shifts in resources or FTE strategic? For this task, the output for each workgroup was a prioritized list of research activities of importance to the Regions. The results of these workgroup reviews were then used by the OSW and Superfund representatives to the Land Research Coordination Team to better represent program views to ORD during research planning. The Land RCT is committed to communicating to Regional managers, the workgroups, and other regional groups any shifts in the research program that reflect Regional and Program Office priorities. 11 ------- Needs for Oil Program and Leaking Underground Storage Tank (LUST) Research The Oil Program research needs are presented in Appendix A. They are based on discussions with OEM Oil Program staff and support the National Contingency Plan Product Schedule or are related to recent statutory requirements. OUST research needs are included in Appendix A under LTG 1. They are based on discussions with office staff and regulatory requirements. 4.3 Need for Identification Process in Land Preservation Research Whereas OSRTI operations and programs tend to be addressed at the regional level, RCRA programs tend to be coordinated at the national level and implemented by the states. Therefore, a higher percentage of RCRA research needs assessment and prioritization took place at the headquarters level. A request was made across RCRA regional and headquarters personnel for research needs in addition to those already listed in the previous MYP. Additional needs were added to the culled list of pre-existing needs. Representatives from all RCRA divisions met and prioritized the list into the following categories: Prioritization Criteria: Resource Conservation Challenge (RCC): RCC-related projects should be apriority. Cost: Something that costs less is more likely to be funded than something that costs more. Leveraging: Opportunities to leverage our needs with those of other Offices. Duration: Preferably a year or two. Quantifiable outcomes directly related to RCRA's strategic goals: Can we relate project outcomes (preferably quantita- tively) to the Agency's strategic goals? Clear, narrowly defined scope: A clearer, more narrowly defined project with quantifiable outcomes. Regional priority: Support from (preferably multiple) Regional Offices. Category 1: RCC-related, with a specific product deliverable within 2 years Category 2: important, but less confident it can be accomplished in 2 years Category 3: important, requiring research duration longer than 2 years. RCRA management had the opportunity to further review the prioritized list. The research needs for the RCRA program and associated ORD research are presented in Appendix A. 4.4 Research Shifts in Program Related to OSWER and Regional Priorities The Land RCT received the prioritizations of the regional workgroups and evaluated the higher priority topics. The workgroups evaluated research needs along with the current research program. The higher priority research from each workgroup (typically 4-6 research needs) were evaluated by the RCT, and ORD wrote a response for each of these, which was (a) a shift in the research program, (b) confirmation that current research addressed the need, or (c) the RCT was unable to address the need. For most of the higher research needs, the RCT was able to shift the research program or the current program addressed the need. Examples of research shifts: 12 ------- Ground water research: increased research effort for ground water-surface water (GW- SW) and VI by redirection of the Soil VOC's sampling guide to "Sampling Protocol for Subsurface Vapors" (VI support). Geophysics work was redirected to include a geophysics tool box to monitor natural attenuation for site managers. Contaminated sediments research: the highest and higher research needs were being addressed by the current research program. Site characterization research: real-time monitoring methods for ground water, and a shift of bioanalytical work from soil to ground water matrix to support rapid field- screening techniques. Bioavailability of arsenic in soil was also a high-priority need. Engineering research: The metal speciation need was discussed above and will be an ongoing issue. A short-term project on mining issues was also initiated. 5.0 Development of the Research Program This version of the ORD Land MYP was developed using a process designed to focus on client priorities (OSWER and the EPA Regions), coordinate with other Agencies and organizations engaged in research on related topics, consider scientific advice from independent bodies (e.g., EPA SAB and BOSC), incorporate PART measures in the accountability of the program, acknowledge ongoing research activities, build upon previous planning efforts, and be consistent with ORD mission and capabilities. The core planning/writing team for the Land MYP consists of the ORD Land National Program Director, Assistant Directors of ORD Labs and Centers, and liaisons from the client offices (OSRTI, OSW, and the regions). The team met regularly, either face-to-face or by telephone, and proceeded through the following tasks: identifying desired program outcomes (LTGs) reviewing BOSC and SAB peer review recommendations reviewing ORD strategic decisions identifying scientific questions and research needs that must be answered and addressed to achieve the desired outcomes identifying ongoing and previously planned research projects and outputs responsive to the scientific questions and research needs determining program and regional priorities for the research needs and ongoing/planned research projects and outputs proposing and prioritizing additional or alternative projects and outputs. As practicable, prioritization criteria were developed and applied, but programmatic decisions were made ultimately by the National Program Directors (NPDs) considering all of the above inputs. Major goals, which must be achieved in order to successfully address the research needs, were developed for each year (called annual performance goals, or APGs). These APGs were developed through dialogue between the Labs/Centers, the clients, and the planning team. 13 ------- Once the research needs to be pursued were identified, and the APGs were agreed upon in terms of nature and Lab/Center responsibility, the process of determining how to meet those research needs and APGs was a bottom-up process. Each ORD Lab and Center accomplished this task using a process consistent with their mission and culture. The result of these Lab/Center-specific deliberations consisted of lists of proposed APMs that the organizations expect to produce as milestones toward fulfilling their commitment to achieve the APG and resolve the critical research need. The proposed APMs were reviewed by the planning team to ensure understanding and agreement that their delivery would fulfill the Lab/Center's commitment. 5.1 Changes in the Research Program Addressing Customer Priorities Section 4 presented the process used to identify and address program office and regional research needs. A table, organized by research themes, presented client research needs and the current and planned research addressing the research need (Appendix A). This table was useful for the RCT to visualize areas where we were meeting research needs, partially meeting needs, or not addressing a research need. Both the prioritization process that the RRAWG performed and the categories that the OSW generated helped to focus the RCT on addressing the higher priority needs. Addressing Peer-Review Recommendations In developing the research program, recommendations from the 2004 SAB review of the MYPs were incorporated into the revised MYP. The SAB supported merging the two OSWER- oriented MYPs and wanted a stronger connection of the research to the EPA Strategic Plan. The panel stressed rewriting the LTGs to move toward "outcomes" and to address emerging issues, and they suggested that more information be presented on how research is prioritized. The LRP incorporated the majority of SAB's suggestions (Appendix D). A BOSC external peer review of the research program and draft MYP was conducted in December 2005. The panel also made recommendations for improvements in the MYP, such as readability of the document, performance metrics and outcomes, use of research questions, and other aspects on the progression of research. Emerging needs were also stressed for areas such as nanotechnology and mining wastes. This document is responsive to the panel's recommendations. The BOSC comments and the EPA responses are in Appendix D. In combining the MYPs, the number of LTGs was reduced from six to two. This reflected PART Guidance that a program should have a limited number of specific long-term performance measures that focus on outcomes and reflect the purpose of the program. The OMB Research & Development (R&D) Investment Criteria, Appendix A (http://www.whitehouse.gov/omb/part/), stress relevance, quality, and performance of research 14 ------- programs. The LRP was evaluated by the OMB PART in 2006 and received an adequate rating. Long-term and annual measures to track performance were negotiated with OMB and reflect additional measures of program efficiency and effectiveness (Appendix F). OKD Strategic Directions An additional factor was responding to strategic priorities within the ORD research program. Responding to support initiatives and shifting staff to focus on higher priority research resulted in shifts in the research program. 5.2 Changes in the MYP Programs Significant programmatic changes were made in the LRP in response to BOSC and SAB recommendations, particularly addressing emerging issues. The RCT decided to make a strategic shift in the research program to conduct nanomaterial F&T research and establish the program as the leader across the Federal government in this research theme. This work will complement funded Science-to-Achieve-Results (STAR) grants. The Agency's efforts are 2 coordinated with other federal agencies through the National Nanotechnology Initiative (NNI), which the Administration has identified as a FY 2008 research and development budget priority. The RCT also decided to more broadly support the Brownfields program research needs in the land revitalization area through an enhanced research effort. Mining waste treatment and monitoring efforts will also be increased. Of decreased emphasis will be combustion research, multimedia modeling, and analytical method development. The Hazardous Substance Research Centers (HSRCs) were universities funded with 5- year grants to conduct basic research, with each center focusing on a specific topic such as contaminated sediments, mining or urban issues. The HSRCs provided research, technology transfer, and community outreach that addressed hazardous substance problems of concern to the ten EPA regions. Funding for the HSRCs was eliminated in FY05, and ORD has attempted to mitigate their loss through an MOU with NIEHS and through other collaboration activities with Federal agencies that provide grants to universities in the remediation area. Funding for the Superfund Innovative Technology Evaluation (SITE) Program was eliminated in FY06. The program was judged to be mature and had accomplished many of its goals. The purpose of the program was to accelerate acceptance of newly developed tools and technologies, largely arising from the private sector. The SITE program evaluated characterization, monitoring, and remediation approaches and produced reports that project managers use to gain confidence in selecting innovative tools and technologies for their sites. ORD is working with the Department 2 For more information, see http://www.nano.gov/.

Table 1. Level of Emphasis for Research Themes Research Theme Long-Term Goal 1 Contaminated Sediments Ground Water Multimedia Hazardous Substance Research Centers Superfund Innovative Technology Evaluation Long-Term Goal 2 Materials Management Nanomaterial F&T Multimedia Modeling Revitalization Resource Conservation Emphasis Level Level Increased for mining; decreased for analytical methods Eliminated in FY05 budget development Eliminated in FY06 budget development Combustion eliminated in FY07 Initiated leveraging from 3MRA to nanomaterials Focused on nanotechnology; decreased model development Brownfields increased Decreased level of effort Mitigation MOU with NIEHS Superfund grants Increased interaction with DOD ESTCP technology program 5.3 Program Description The purpose of the restoration research is to provide improved scientific knowledge and develop and apply more cost-effective tools, models, and methods to inform decisions on land restoration. The purpose of the preservation research is to provide improved scientific knowledge and develop and apply more cost-effective tools, models, and methods to manage material streams and inform land revitalization decisions. ORD is in a unique position to link applied research to effective technical support at the site-specific level. This linkage is enhanced through eight ORD Technical Support Centers (see Appendix H), which exist to address inquiries from site managers and regional risk assessors and 16 ------- engineers. ORD also has a liaison stationed in each region to facilitate the application of ORD science to address site-specific issues. ORD researchers partner with OSWER and Regional scientists and engineers to produce OSWER guidance documents, OSWER Directives, and fact sheets. They serve with regional staff on advisory groups and work with them to conduct technology demonstrations. Collaboration Across Federal Agencies EPA expends substantial effort coordinating with other agencies, including work with the (DOD in its Strategic Environmental Research and Development Program (SERDP) and the ESTCP, the Department of Energy (DOE), National Institute of Environmental Health Sciences (NIEHS), Agency for Toxic Substances and Disease Registry (ATSDR), Department of the Interior (DOI), and state groups to communicate results, leverage expertise, and collaborate on complex issues. Summary information on EPA collaboration with federal agencies and state groups is presented in Appendix H by topic area. The research topics and associated collaborative activities and products show the degree of collaboration and leveraging of technical expertise across the federal government on restoration and preservation issues. In addition to the above activities in 2006, we established an Interagency Collaboration on Environmental Remediation Research (ICERR) Workgroup to develop increased understanding of federal environmental remediation research programs among the EPA, DOE, NIEHS, National Science Foundation (NSF), and DOD SERDP through the following: Program manager-level research program reviews Identification of research areas among the agencies to enhance collaboration, encourage leveraging of research, and minimization of duplicative research. Long-Term Goal (LTG) Development In the RCT, there were discussions about how to combine the two previous MYPs, and converting the six LTGs into two LTGs. In addition, the RCT had facilitated meetings to develop client oriented goals and outcomes. LTG 1 was primarily directed at ORD research that supported remediation activities of OSWER and the regions. This included Superfund, Oil Spills, and LUST research. The process to determine what research to conduct was presented in Sections 4.2-4.4. Three research themes are contained in LTG 1: contaminated sediments, ground water contamination, and multimedia and analytical methods. LTG 2 supports the prevention research needs of OSW and emerging issues. Research themes are resource conservation and management of material streams, which will include emerging material streams, specifically, nanomaterial fate and transport. 17 ------- Each LTG includes the following: a. Definition and key research questions within the LTG research themes b. Research theme: Responses to key research questions and a description of the research program c. Performance measures: Wiring diagram of research theme APGs leading to the LTG. Land Research Program Long-Term Goals (LTGs) LTG 1: Clients request and apply ORD research products and services needed for mitigation, management, and long-term stewardship of contaminated sites. LTG 2: Clients request and apply ORD research products and services needed to manage material streams, address emerging material streams, and conserve resources. 5.4 Long-Term Goal 1: Research Questions, Description of Research Program, and Performance Measures LTG 1: Clients request and apply ORD research products and services needed for mitigation, management, and long-term stewardship of contaminated sites. To achieve this goal, ORD must identify accurately the scientific uncertainties which, when addressed, make the clients' mandated responsibilities and actions most cost-effective and scientifically defensible. From the clients' perspective, activities related to mitigation, management, and long-term stewardship at contaminated sites are dependent on the environmental medium of concern, and the needs for research vary accordingly. For that reason, this LTG is organized according to the following themes: contaminated sediments, ground water contamination, and multimedia and analytical methods. Each theme is described separately below, guided by key research questions and producing performance measures addressing the LTG. 5.4.1 Theme: Contaminated Sediments Key research questions addressed: How can we build consensus in application of F&T models of contaminants and improve modeling use in site decisions? 18 ------- What is the most appropriate framework for modeling F&T of contaminants under different remedial alternatives? When dredging is used to remediate a sediment site, what are the (a) effects on biota, (b) F&T of resuspended contaminants, (c) measurement tools, and (d) management options? How effective are alternative technologies vs. sediment dredging? What are the critical tissue residues to use as screening levels for aquatic organisms exposed to persistent bioaccumulative toxins (PBTs)? How can we use field data and bioaccumulation models to extrapolate bioaccumulation of PBTs across ecosystems? What are monitoring and measurement tools to improve the characterization of sediments and their biota? How do we identify sediment remediation options that minimize contaminant accumulation in fish and impacts on benthic communities? At contaminated sediment sites, the Superfund program must decide whether to leave the site alone or select a remedial option. These decisions are based in part on the relative risks to the environment and health posed by each alternative. Whatever decision is made at a site, the Superfund program must have an understanding of the potential risks posed by the remedial action itself, and an understanding of how best to monitor effectiveness of the action over time. The research questions, when addressed adequately, will provide an improved scientific basis for these decisions. Because risk posed by a given contaminant concentration in sediment is likely to be related to the depth at which that contamination is found, the ability to sample selectively the top layers of sediment is important. Traditional approaches to sampling disturb the sediment surface, rendering assessment of distribution within layers inaccurate. This research addresses measurement tools to characterize sediments, specifically, how can the sediment surface be sampled without disturbing it? Based on determination of the best principles of existing commercially available devices, work was initiated on a sampling device. A prototype undisturbed sediment sampler (USS) has been developed and has undergone initial testing, resulting in technical improvements and modifications. Currently, field testing in different sedimentary environments is being planned to test the robustness of the sampler, along with technology transfer activities. Decision makers must forecast changes in nature and extent of contamination under various management, temporal, and hydrodynamic scenarios. This research is therefore addressing F&T questions such as: What is the most appropriate framework for modeling F&T of contaminants under different remedial alternatives? Existing contaminated sediment transport models and bioaccumulation models were evaluated to determine their capabilities and limitations and to identify capabilities that should be added to these models. A three-step plan was developed: 19 ------- 1. Capability of the public domain F&T model that ranked highest in the model evaluation (Environmental Fluid Dynamic Code, or EFDC) was augmented to include: a. a sediment consolidation-contaminant transport model to simulate consolidation due to sediment self-weight and cap overburden, and the resulting contaminant flux. b. a model to simulate wave-induced resuspension of highly organic sediments and associated contaminants. The sediment transport, eutrophication, and diagenesis modules in EFDC will be linked to account for resuspension of inorganic sediment and organic carbon, and for the settling and deposition of both inorganic sediment and organic matter. 2. The upgraded EFDC was tested in several types of water bodies, including: a. a salt-wedge estuary (Lower Duwamish Waterway) b. a reservoir (Lake Hartwell) c. a partially stratified estuary (St. Johns River) d. a river (Housatonic River). EFDC will also be applied to Mobile Bay to test its ability to simulate formation and movement of fluid mud. The application of this research tool directly to these sites has improved the capability of the site-specific models to support management decisions. 3. The final step will be to develop the framework for modeling remedial alternatives. The framework will include: a. a watershed loading model b. the enhanced EFDC model c. a bioaccumulation model d. protocols for applying the component models e. software for evaluating uncertainties in a modeling study. Understanding the toxic properties of contaminants is essential to understanding the risks associated with contamination. To a large extent, this is a general problem in toxicology, not restricted to contaminated sediments. The ORD Land Research Program is focused on those contaminants that tend to be persistent and bioaccumulate within organisms, since they pose the most evident long-term risk. Furthermore, since the risk to humans is primarily through exposure to other organisms within whom contaminants may have accumulated, the future ORD focus of this program is largely on ecological receptors. More specifically, ORD research is directed to provide the site-specific risk assessor with tools to make risk predictions based on extrapolation from an understanding of food web and bioavailability / bioaccumulation relationships and on the impact of remediation alternatives on these variables and their relationships. ORD's research will establish and improve understanding of causal relationships between sediment contamination and chemical residues and exposure to aquatic organisms. This 20 ------- research will also provide tools for use in defining critical sediment and tissue residue thresholds between acceptable and unacceptable effects for aquatic and aquatic dependent organisms. Key research foci include the following: Determining the critical tissue residues to use as screening levels for aquatic organisms exposed to PBTs. Research consists of assembling and evaluating a residue-effects database for polychlorinated biphenyls (PCBs), polychlorinated dibenzodioxins (PCDDs), and polychlorinated dibenzofurans (PCDFs) for aquatic and aquatic-dependent organisms. The evaluation is identifying (a) major gaps in PCB residue-effect data; (2) the extent to which risk estimates are altered significantly by the manner in which PCB is expressed (e.g., total PCB, Aroclors, congeners, and dioxin-like congeners); and (3) methods, tools, and techniques for screening and evaluating the toxicity data as well as for deriving residue-effect relationships with varying amounts and types of laboratory- derived toxicological data. Determining how to extrapolate field-measured bioaccumulation data across species, ecosystem, and/or time through development of a hybrid empirical/modeling approach. Determining the impact of incomplete removal or resuspension of contaminated sediments on the aquatic organisms. Determining the conditions under which different approaches to measuring the integrity of benthic organism communities at sites are most suited. Current remediation approaches to addressing contaminated sediments, include dredging, capping, and MNA. OSRTI must decide which of these options best suits a particular site. In addition, considering the costs, strengths, and limitations of these approaches in the context of the wide variety of sites to which they must be applied, development of new treatment approaches is desirable. ORD's research program is designed to provide a better understanding of the traditional risk management options and to investigate alternative options. To improve understanding of existing risk management options, ORD will continue to evaluate post-dredging residuals models through case study and field evaluation. Field studies will be conducted to evaluate post-dredging residuals and implement innovative monitoring tools, such as core profiling techniques, semi-permeable membrane devices, volatilization chambers, and innovative techniques for evaluating capping technologies yet to be applied for monitoring dredging operations. ORD is investigating several alternative sediment remedies with the potential to be more cost-effective than conventional dredging or capping remedies. An emphasis will be placed on bioremediation of organics, electrochemical degradation, and conventional and reactive caps. In coordination with the U.S. Army Corps of Engineers, and in association with the Strategic Environmental Research and Development Program (SERDP), ORD will complete a number of research projects to evaluate the field performance of dredging and capping and to improve understanding of the best management practices. 21 ------- ORD will develop or test the applicability of a number of tools for monitoring contaminated sediment and associated risks, which can then be applied to monitoring remedy performance. The tools include sampling devices suitable to investigate contaminant migration into natural or constructed sediment caps and migration from the sediment into the overlying water column and atmosphere as well as monitoring techniques used in developing and evaluating potential remedies. The models of sediment transport and uptake by organisms will provide insight into the time scale appropriate for implementing the monitoring techniques to measure progress toward the cleanup goal. We expect the program office to work with ORD to provide this information to remedial project managers through fact sheets, guidance, or other technology transfer mechanisms. 5.4.2 Theme: Ground Water Contaminated ground water is a problem at most Superfund sites and at virtually all LUST corrective action sites as well as many RCRA Corrective Action and Brownfield sites. We now know that remedies are taking much longer than originally anticipated. Operation and maintenance costs are substantial and conventional remedies may not be able to achieve cleanup objectives in reasonable time frames or at all, particularly for contaminants that are newly found to pose risks at concentrations once deemed acceptable. The research is driven by science and technology questions related to characterizing the contamination and developing cost-effective and efficient remedial options. These questions are addressed differently for three classes of problematic yet pervasive ground water contaminants DNAPLs, inorganic species, and fuel components, including oxygenatesand for hydrogeologic regimes that challenge existing characterization and remediation options. Key research questions addressed: What are alternatives to pump and treat methods? What characterization, sampling, and analytical methods will reduce the uncertainty in F&T models and will improve exposure estimates supporting risk assessments? For DNAPL research: (1) How much DNAPL must be removed to be protective of human health and the environment, and (2) Are current technologies adequate to achieve this level of removal? What long-term performance tools are needed to evaluate the effectiveness of MNA? Can PRBs be applied to treat inorganic GW contamination? How can modeling and sampling methods be improved to reduce uncertainty in analysis of vapor intrusion into homes? What are strategic approaches to assess ground water-surface water interactions? How can F&T models of fuel components be improved to reduce uncertainty? What are cost-effective approaches for characterization and remediation of fractured rock settings? 22 ------- What are the factors and improvements that could be applied to natural or commercial processes to reduce the impact of mining sites on surface and ground waters? To what extent are the scientific advances in ground water research impacting the long- term stewardship of hazardous waste sites? The remediation of subsurface formations contaminated by non-aqueous phase liquids (NAPLs) is a major impediment to the restoration of many hazardous waste sites. NAPLs are classified as those lighter than water (LNAPL) or denser than water (DNAPL) and can serve as long-term sources of contamination impacting both ground water and surface water. The remediation of DNAPL-contaminated sites is particularly challenging because DNAPLs can migrate deep through the saturated zone, leaving a trail of hydraulically trapped organic liquid. The rates and extent of migration are dependent on physical and chemical properties of the DNAPL and hydrodynamic properties of the subsurface. The resultant spatial distribution of DNAPLs can be very complex and difficult to locate and characterize. The region of the subsurface containing DNAPL, either as randomly distributed pools of organic liquid or sub- zones at residual saturations, is termed the DNAPL source zone. Constituents from trapped DNAPL slowly partition into ground water to create and sustain dissolved contaminant plumes that may extend significant distances from the source zone. The extent of the dissolved plume will be determined by contaminant flux from the source and the capacity of the subsurface to attenuate the migrating dissolved contaminant (Figure 4). The most prevalent DNAPLs (halogenated organic solvents, e.g., trichloroethylene and tetrachloroethylene) are not readily degraded and relatively large dissolved plumes of these chemicals are frequently observed. Control Plane Compliance Plane Figure 4. DNAPL Source Zone and Dissolved Plume Characterization of ground water contamination is a critical issue, particularly for DNAPLs, which do not behave like dissolved contaminants, and for vapor intrusion into buildings which has parameter uncertainty issues for modeling exposure and migration of ground water contaminants into buildings. Research will produce characterization, sampling, and analytical methods to reduce the uncertainty in F&T models, which will improve exposure estimates supporting risk assessments. Improved understanding of the nature and extent of contamination will also influence selection and implementation of remedial actions and will result in more accurate cost estimates. Research on releases from leaking underground fuel storage tanks will include oxygenates that represent a characterization and remediation challenge in themselves as well as affecting the behavior and treatment of hydrocarbon fuel components. F&T studies will lead to 23 ------- improved modeling capability that predicts plume behavior and the effectiveness of remedial alternatives. Development will continue on a set of on-line calculators and a modeling system intended to be used by states in assessing the large number of LUST corrective action sites. Development or enhancement of remediation technologies on challenging ground water contamination issues is a significant segment of the research effort. Recent research and demonstration projects have led to new alternatives to conventional pump-and-treat technologies that are being adopted in the field. Recommendations from an international external panel, addressing the effectiveness of DNAPL source elimination and the options for dealing with inevitable residual contamination, have helped shape the research goals that are being addressed in the research program. Conventional remediation techniques designed for dissolved contaminant removal have proven inadequate for achieving acceptable environmental cleanup goals within reasonable time frames for DNAPL source zones. However, field-scale research conducted by ORD has demonstrated that a high percentage of DNAPL mass can be rapidly depleted from source zones by using aggressive in situ thermal or chemical flushing technologies. Even with these aggressive technologies, the efficiency of DNAPL removal often decays exponentially with increasing mass removed, and complete DNAPL removal may not be technically or economically feasible. For such sites, the key questions are as follows: (1) How much DNAPL must be removed to be protective of human health and the environment, and (2) Are current technologies adequate to achieve this level of removal? To answer these questions we must understand the relationships between DNAPL mass depletion, contaminant mass flux from the source zone, and dissolved plume properties. The ORD DNAPL source remediation research is focused on three critical issues: (1) Demonstration, evaluation, and optimization of DNAPL remediation technologies; (2) Assessment and prediction of the benefits of partial DNAPL depletion; and (3) Development and assessment of integrated DNAPL source remediation approaches. Increasingly, inorganic contamination of ground water resources from arsenic, chromium, perchlorate, and radionuclides is recognized as a significant issue. Sources include large DOE and mining megasites as well as industrial and naturally occurring sources (e.g., arsenic). Remediation of inorganic plumes in ground water follows a dual track of assessing the potential effectiveness of MNA and PRBs, building on successful development of these approaches for organic contaminants. Because metals can't be destroyed, the mechanisms of immobilization are critical to the long-term performance of these approaches. MNA research focuses on identifying the attenuation mechanisms and the anticipated stability of the immobilized metals under anticipated geochemical conditions. One of the field studies will test the accuracy of the recently completed, cross-office framework for how to evaluate the applicability of an MNA remedy for a specific site. Research on PRBs will provide two cases of PRB performance in the near-term. Additional research will evaluate the long-term performance and efficiency of PRBs and extend the range of metals that can be addressed with this technology. 24 ------- Complex hydrogeology impedes the evaluation and remediation of contaminants at sites; additional guidance on effective options for these sites will be provided. Regional experience and research are increasingly identifying the zone of ground water discharge to surface water to be the site of complex interactions. While past research addressed this as it was encountered in field studies, planned research will address the ground water-surface water interaction (GSI) zone more systematically. A summary of the research for PRBs, MNA, and remediation of DNAPL source zones will be documented to determine the impact of each research area with respect to the long-term stewardship of hazardous waste sites. An evaluation of the state of the science is needed for each research area to determine the actual impact of the research on the stewardship of the sites. 5.4.3 Theme: Multimedia and Technical Support Program Key research questions addressed: What cost-effective analytical and statistical methods are needed to support site characterization issues? What improvement will reduce uncertainty in modeling of oil spill fate and effects? What are the impacts of new or improved oil spill countermeasure approaches on fresh and saline water environments? What are the factors and improvements that can be applied to natural or commercial processes to reduce the impact of mining sites on surface and ground waters? The Office of Solid Waste and Emergency Response (OSWER) and its Regional Offices require innovative methods and techniques to solve the difficult site characterization, contaminant containment, and risk management problems found at numerous contaminated sites throughout the United States. The research under the Multimedia and Technical Support theme includes development of analytical methods, field sampling guidance, statistical software, oils spills dispersal modeling and remediation, monitoring and remediation technologies for mining sites (specifically bioreactors), and the technical support infrastructure needed to move the products of these R&D activities from the lab and into the hands of site managers and other decision makers. Site Characterization, Analytical Methods, and Statistical Analysis This topic is an integral step in site characterization. Before predictions of contaminant F&T can be made, risk assessments performed, or remediation options evaluated, an understanding of the types of contaminants present and the extent of their dispersal in the environment must be acquired. Analytical methods research supports this understanding by improving cost, accuracy, portability, and speed of analysis for the most common or most difficult to analyze inorganic and organic contaminants. Immunochemical and other bioanalytical methods can allow rapid on-site characterization and monitoring of remediation 25 ------- and cleanup activities at Superfund sites. Immunoassay detection, immunoaffinity chromatography sample preparations, electrochemical immunosensors, and coupled immunoassay detection/chromatography/mass spectrometry methods will be developed that allow for rapid, accurate, and precise quantification of various contaminants in the field. The use of these field methods will allow real time decisions to be made on additional sampling needs, delineating contaminant distributions, and determining the effectiveness of remedial actions. Future bioanalytical work will include development of dioxin assays for soil and sediments and a shift in focus to real-time and more cost-effective ground water analytical methods in response to Regional Research Advisory Groups client requests for additional analytical methods development for the ground water medium. Additional analytical method development will include methyl mercury analyses in liver and muscle tissues for fish taken from Superfund mercury-impacted areas and the use of semi- permeable membranes and isotope dilution mass spectrometry for PCB analyses. The assessment and cleanup of sites contaminated with multiple contaminants in multiple media is a complex process in which many factors can influence the validity and confidence in the final data used to decide on future actions at the site. Research in statistical sampling and data analysis is aimed at improving or developing statistical methods to reduce data uncertainty in the experiment or measurement process for environmental decision making. Peer-reviewed journal publications, book chapters, and guidance documents on robust data analysis, including multivariate outlier testing, causal outlier variable methods, principal component analysis, discriminant analysis, censored data analysis, multivariate geostatistical methods, and methods in parallel space, will be some of the outputs of this work. For site managers, the SCOUT statistical software package will be upgraded with new robust statistical procedures and a geostatistical model that allow for more advanced statistical techniques to be used in the assessment of the validity of analytical data. A field-sampling guidance document to identify methods and techniques to eliminate bias that occurs during field sampling will also be developed. This research will help site managers understand the driving factors and tradeoffs affecting environmental sampling design and to assess the validity (with increased confidence) of the data used during decision making on site characterization and remediation efforts. Oil Spills Research The ORD oil spills research program supports the preparedness and response functions of the Oil Spills Program within OSRTI, funded by a separate trust fund. Research is focused in three areas: developing a better understanding of fate and effects of spilled oil; development of testing protocols for spill control; and development of response options. Developing modeling methodologies to assess the fate and effects of oil spills in fresh and saline waters will provide important tools, methods, models, data, guidance, and technical support to site managers and other decision makers and stakeholders to use in assessing and cleaning up spills of petroleum and non-petroleum oils. This work will provide essential information on dispersion and effects of dispersant treatments on spilled petroleum, non- 26 ------- petroleum oils, and their constituents. Some of the major outputs of this work will be a report on linkage of the EPA research object-oriented-oil spill model (ERO3S) oil spill model to surface water transport and quality models, assessments of optimal parameters for nutrient application for oil spill bioremediation on beaches, and assessments of optimal conditions for the bioremediation of wetlands. A major goal of this research effort is to develop a multicomponent mass-balance-based model for simulating transport of spilled oils with and without dispersant treatments. Selection of appropriate risk management options in oil spill scenarios is supported through the development of protocols to evaluate spill response products and through development of new risk management strategies for petroleum and non-petroleum oil spills in fresh and saline environments. By FY07, the first phase of laboratory and field studies will be completed on the risk management and fate and effects of oil in fresh and saline environments. This will include work on petroleum and fuel emulsions, chemical and biological treatment, climatic effects on oil spills, dispersant modeling, and ecosystem exposure as a function of various response scenarios. By FY08, risk management strategies will be developed for non- petroleum oil spills. ORD, in collaboration with Fisheries and Oceans Canada, has funded the construction of a wave tank in Halifax, Nova Scotia, which generates breaking waves reproducibly. The wave tank will allow quantification of dispersant efficacy as a function of sea turbulence and the development of correlations between laboratory and wave tank data. In collaboration with Canada, work is also underway to develop a surface-washing agent to remove oil from coated surfaces, followed by round-robin validation testing. Mining One of the highest priorities and needs of many of the EPA Regions has been mine water remediation. It is estimated that there are over 400,000 abandoned mine sites in the western United States, and almost all of these sites contain contaminated waste and water. In the past 5 years, technical assistance for active and passive treatment of mine water has accounted for upwards of 25 % of the engineering assistance requests. While active treatment has been utilized at the larger mining mega-sites, there is a need for treatment systems that can be located in remote areas and at higher elevations. In these areas, there is no power source, access is restrictive, and the treatment season is very short because of winter weather. ORD has been actively supporting the research and acceptance of passive systems that require little power, have an acceptable operational life, and rely on chemical precipitation and adsorption as well as biological processes (sulfate-reducing bacteria and other microorganisms) to treat the water. The science is still in its infancy and has to be proven effective to meet effluent criteria and sustainable over longer periods of time. Providing Technical Support to the Regions and States Providing technical support to the Regions and states is an important part of the ORD LRP. Through the technical support program, the products of ORD's R&D activities move from the laboratories and field studies into the hands of site managers and other decision makers. In 27 ------- addition to this technology transfer function, the technical support program provides site-specific assistance in response to regional site manager requests. Other aspects of the technical support program include technology transfer via hotlines, websites, workshops, and client-oriented publications. OSWER and the regions have consistently cited technical support, and particularly site-specific assistance, as their top priority for ORD. In addition to ORD resources of FTE and extramural funds, OSWER and the regions provide Superfund extramural funds directly to several of the centers. Except where restricted by trust fund limitations, the centers provide support for Superfund, including Sediments, Ground Water/Surface Water, Multimedia, Mine Waste and Water, Modeling, RCRA, and Brownfields, to project managers. In most years, more than 500 assistance activities are completed for more than 100 sites. In Appendix H, the eight ORD Technical Support Centers are described. Because technical support activities are request driven, outputs and products are not listed in Table 4. Instead, the Centers provide annual reports to the Program Office, and issues are discussed at the annual progress review. 5.4.4 Performance Measures: Wiring Diagram of Research Theme APGs Leading to LTG Figure 5 presents the path of contaminated sediments, ground water, and multimedia research, presenting the completed APGs as performance measures of progress toward the LTG. Contaminated sediment APGs address key issues in sediment remediation; improved F&T modeling; measures of risk reduction after remediation; estimates of residual contamination after dredging; methods to mitigate polyaromatic hydrocarbons (PAHs) and metals; and performance data on capping, MNR, and alternate remediation methods.

Long-Term Goal 2: Research Questions, Description of Research Program, and Performance Measures LTG 2: Clients request and apply ORD research products and services needed to manage material streams, address emerging material streams, and conserve resources. The Office of Solid Waste, state agencies, and local governments make decisions about materials use, management, and ultimate disposition. Over the past several years, conservation of resources and reuse of materials formerly considered waste has received considerable attention. The research program has been evolving to consider not only appropriate waste disposal but also beneficial use, avoidance of more toxic materials, and operation of waste management to conserve capacity and produce energy. To address emerging material management issues, a strategic shift in the research program was made to conduct nanomaterial F&T research and establish the program as the leader across the federal government in this research area. To achieve this goal, ORD must identify accurately the scientific uncertainties which, when addressed, make the clients' mandated responsibilities and actions most cost-effective and scientifically defensible. From the clients' perspective, activities related to the nature of material streams, mitigation and management of materials, conservation of resources and long-term ------- stewardship are important. Because the program office, regions, and states are still evaluating the highest priority material streams, we anticipate that the specific materials covered in the research program described below may change over the implementation period. The annual program review and budget refinement cycle provide the forum for ORD and clients to concur on changes in emphasis. 5.5.1 Theme: Resource Conservation Key research questions addressed: What are the risk reductions from waste minimization programs? What models and tools can be developed and applied to support community decisions on Brownfields? What information on sustainable waste management practices can be integrated to support the Resource Conservation Challenge? What are the metrics for sustainability in Land Revitalization/Brownfields efforts, and how can they be applied in urban planning? ORD has conducted extensive development of a modeling framework, originally intended to evaluate relative risks on a national basis, of various waste disposal options for use in regulatory decision making. Because OSW has now completed the majority of its mandated regulations, the need for modeling alternative risks has evolved to addressing questions related to regional or site-specific assessments, newer waste streams (e.g., electronic waste, nanomaterials), and the new emphasis on resource conservation and reuse through largely voluntary programs. In addition to modeling, material evaluation by speciation and leach testing is needed to understand what hazardous constituents might be released in various disposal and use scenarios. OSW has targeted specific materials for volume reduction to minimize generation of hazardous waste and other materials for beneficial use to demonstrate one facet of resource conservation. Research is planned to support these efforts with case studies. A modeling study has already begun to evaluate the risk reduction achieved by reducing waste minimization priority chemicals (WMPCs). The 3MRA model is being used to develop comparative assessments of ecological and human populations risk reduction resulting from achievement of current and future waste reduction goals for up to 9 of 31 WMPCs (e.g., Pb, Hg, trichlorinated dibenzodioxins [TCDD]). An outcome of this work will be an ability to quantify, on a national scale, the reduction in risk to human and ecological receptors resulting from the reduction of selected WMPCs found within waste streams reaching industrial solid waste management facilities. Another case study will evaluate alternatives for lead in industrial usage. Emphasis will be placed on comparing the risks from lead use and release with risks from potential substitute materials. Multimedia risk assessment methodologies for the Resource Conservation Challenge will be built on prior collaborative work between ORD and OSW that developed the Multimedia, 32 ------- Multipathway, and Multi-receptor Risk Assessment (3MRA) modeling system in support of the Hazardous Waste Identification Rule (HWIR). The 3MRA modeling system is composed of 17 science sub-models that simulate source contaminant releases to the environment, F&T of contaminants through soil, air, and water media; and evaluation of exposure and risk for both human and ecological (terrestrial and aquatic) receptor populations. A critical feature of the 3MRA is the software system design. The Framework for Risk Analysis in Multimedia Environmental Systems (FRAMES) is a software infrastructure designed to facilitate the development, testing, application, and maintenance of science-based modeling systems such as the 17 modules of 3MRA. The 3MRA modeling system received a very positive review by the SAB in 2005. Given the application of multimedia media modeling techniques to varying problems, a collaborative relationship was formalized in a Memorandum of Understanding (MOU), initiated in June 2001, and involves nine federal agencies. The purpose of the MOU is to establish a framework for facilitating cooperation and coordination among the signatory agencies in their R&D of multimedia environmental models. Due to the shift in modeling focus to nanomaterials, the development of 3MRA will be slowed. However, the transfer of the sophisticated model to address other program office and regional needs will be conducted. There are increasing quality assurance requirements being placed on regulators to address uncertainty analysis, sensitivity analysis, and parameter estimation (UA/SA/PE) in model-supported, risk-based decision making. In addition, understanding and quantifying the uncertainty associated with exposure assessments is requisite for developing risk estimates with scientifically defensible confidence limits. Specific components of this research effort include development of UA/SA/PE tools that can serve multiple Program Office needs in meeting new quality assurance standards (e.g., EPA's Council on Regulatory Environmental Modeling, Data Quality Guidelines) and model simulation demands for national, regional, and site-specific studies. Brownfields and Land Revitalization Use of greenspace contributes to urban sprawl, reduction of natural resources, and destruction of natural systems. Revitalization of previously used land (e.g., brownfields) does not always occur because of obstacles related to real and/or perceived contamination (e.g., fear of uncertainty and potential liability, lack of financial resources to remove contamination, lack of vision, lack of communication, fear of time commitment, etc.). It is important to encourage the revitalization of previously used lands such that existing social and environmental systems are maintained and even enhanced in an economically advantageous manner. Through the development of tools, approaches, methods, and technologies, we can facilitate revitalization of potentially contaminated sites while encouraging stakeholders to incorporate a balance of social, economic, and environmental interests and objectives into growth and development that will not negatively impact current or future generations. For example, a decision support tool called SMARTe will inform revitalization stakeholders about the entire revitalization process, help them overcome obstacles to revitalization, and assist them in the complex selection of reuse options. A standardized method for soil gas measurements will 33 ------- reduce the error associated with soil-gas sampling and the movement of vapors (i.e., vapor intrusion) into buildings/homes. ORD will continue to develop GIS and Remote Sensing Tools to inventory Brownfield sites. Sustainability Planning Criteria will be developed, implemented, and evaluated for land use planning so communities and towns can develop to meet citizen needs and expectations while leaving the essential attributes of economic, social, and ecological systems intact and able to sustain future generations. Training and technical support to OSWER, regions, states, and local governments will continue to support the remediation of Brownfield sites. The Brownfields efforts have been carried out through an ORD FTE and an intra-agency funding transfer from OSWER to ORD; these products are reflected in this plan. 5.5.2 Theme: Materials ManagementEmerging Research Nanomaterial Fate and Transport (F&T) Key research questions addressed: Which engineered nanomaterials have a high potential for release and exposure from a life-cycle perspective? What technologies exist, can be modified, or need to be developed to detect and monitor releases of and exposures to engineered materials? What physical and chemical properties and processes determine the environmental release, fate, and transport of engineered nanomaterials? What are the exposure routes for human and ecological receptors to engineered nanomaterials? What are the forms of the engineered nanomaterials to which these receptors will be exposed? What properties of engineered materials are associated with potential hazard? What techniques and tools exist, can be modified, or need to be developed for detecting and predicting hazards of engineered nanomaterials? What are the prioritized information gaps that need to be addressed to support comprehensive assessments of ecological and human health risks of nanomaterials? How will EPA's risk assessment approaches need to be modified to accommodate the special properties of nanomaterials? For nanotechnology F&T research, the primary objectives will be to determine the physicochemical properties and processes controlling nanomaterial movement through soil and aquatic ecosystems. The research will also focus on the engineering factors to understand the transformation, transport, and longevity of the engineered nanomaterials. Specific research will also investigate the life-cycle assessment of nanomaterials, particularly to understand their fate for emissions and releases. Research questions include the identification of system parameters that alter the surface characteristics of nanomaterials through aggregation (e.g., pH effects), complexation (e.g., surface complexation by dissolved organic carbon), or changes in oxidation state (e.g., chemically or biologically mediated electron transfer). This work will provide the 34 ------- basis for prioritizing potential ecological exposure pathways that warrant further exploration. This work will complement funded STAR grants. The Agency's efforts are coordinated with other federal agencies through the National Nanotechnology Initiative (NNI), which the Administration has identified as a FY 2008 R&D budget priority. EPA's nanotechnology research is also guided by a draft research needs document being prepared by the 4 Nanotechnology Environmental and Health Implications Working Group. EPA will develop into the federal lead for environmental F&T research outlined in the NNI draft research needs document. 5.5.3 Theme: Materials ManagementDisposal, Reuse, and Containment Key research questions addressed: What is the mobility of metals in reuse of coal combustion products? What are the appropriate leaching methods to determine chemical mobility in material reuse scenarios? How can landfills be managed to conserve resources? How can the service life of a landfill be extended? How can landfill bioreactors be optimized for performance? What emerging waste materials issues require scoping? Leach Testing for Material Reuse The modeling approach to risk assessment will be supplemented with a modest program to evaluate wastes for their capacity to release hazardous constituents into the environment, either in a disposal setting or in reuse. Leach testing is a normal component of evaluating waste materials for compatibility with the local environment. As the range of potential environments expands (e.g., road bed, use in drywall and concrete, mine filling, land application, etc.), it becomes more critical to be able to simulate the release of hazardous constituents. Over the last several years, ORD has been investigating a range of leaching tests that consider pH, redox state, liquid:solid ratio and other parameters recognized as factors in determining the release of hazardous constituents. These studies will continue, with the aim of validating the predictive capability of a set of tests. This program is complemented and supplemented by an evaluation, under Goal 1-Air, of the application of a particular testing protocol to coal combustion residues (CCRs) and comparison of the results to leachate data from CCR monofills. ORD also plans to evaluate risks from beneficial use of CCRs or other materials that are normally disposed of in landfills. 4 For more information, see http://www.nano.gov/html/society/NEHI.htm. 35 ------- Landfill Research Before varied risk management options can be evaluated and informed selection of the appropriate option made, research is needed to evaluate the existing risk management options and to develop new options when existing management options are insufficient to meet site management goals. Recent accomplishments include completing a multi-site study of alternative covers for landfills, which has resulted in selection of the new technology at both Superfund and RCRA sites and development of an in situ stabilization method for lead that renders it less mobile and less bioavailable. Research in the next 5 years will focus on exploiting the chemical properties of contaminants and their host environment and inherent biological activity to develop new approaches for risk management. Our experience with MNA and recovery, alternative covers, and lead stabilization indicates that more complete understanding of the biogeochemistry of a system can lead to simpler technology and lower cost approaches for mitigation of risk. X-ray analysis tools will be applied to contaminants of concern to elucidate their speciation and interaction with surrounding environmental media and interaction with micro- and macro- organisms to develop approaches to alter the speciation in ways that promote degradation, removal, immobilization, or conversion to biologically less active forms. With respect to traditional landfills, the remaining research needs relate to construction testing and long-term performance of materials used in composite covers and liners. Recent data suggest some performance problems associated with clay and geosynthetic clay liners (GCLs) when used as cover components. Additional work will address fugitive emissions, seismic stability, and development on closed landfills. The National Academy of Sciences will be providing ORD with a report on long-term protectiveness issues in FY08 that will further refine future research needs. Ongoing research on the operation of landfills as bioreactors will continue. Bioreactors can contribute to resource conservation in two ways: (1) Accelerated waste decomposition results in volume recovery, reducing the need to site new landfills, and (2) Accelerated methane production may make energy recovery more economical. ORD has supported OSW in developing the Research Development and Demonstration (RD&D) rule for landfills, which provides flexibility to the states to allow innovative approaches to management of municipal landfills. As a result of this rule, ORD and OSW are working with the states to assist them in evaluating the effectiveness of landfill bioreactors. The research is addressing operation and monitoring parameters as well as evaluating risks such as increased fugitive emissions. Results to date have been incorporated in training and technology transfer materials used by state permitting officials. Combustion has been an ongoing research area and will be eliminated in FY08. In-house work focused on monitoring devices to detect chlorinated dioxins and furans or surrogates and mercury. ORD provided technical support as OSW completed development of maximum achievable control technologies (MACT) regulations for combustion facilities under the Clean 36 ------- Air Act. Emissions monitoring is important to ensure that waste combustors are operated in compliance. The loss of the modest resources in LRP is mitigated by more significant resources in other goals that address air toxics and mercury. 5.5.4. Performance Measures: Wiring Diagram of Research Theme APGs Leading to LTG2 The diagram below (Figure 6) is the research path for resource conservation research supporting LTG 2. The APGs supporting the determination of risks associated with materials include assessing outcomes for reductions in priority chemical streams and leaching methods. Leach testing methods will contribute to assessments of material reuse. Brownfields products will expand the tools and methods to support community decisions on land reuse and urban revitalization. Emerging material management issues addressing nanomaterial F&T APGs will produce products to lay the foundation for understanding key nanomaterial characteristics in the mobility and fate of these materials. Multimedia modeling will address science improvements and support nanomaterial modeling issues. In material management, landfill and bioreactor goals will include research to improve liner performance and service life. The increased utilization of bioreactors at landfills will be promoted through completion of guidance documents on the design, operation, and maintenance of the systems. Management methods for emerging wastes materials will also be addressed. 37 ------- Long-Term Goal 2 Resource Co userva.lion Revitalixation Broivufield Material Management Nano F&T Assessing enviKHiinantal waste priority rltrniar-ib TV 'A ' .Provide iinder^Tng existing applications and models, and databases for emerging: contaminant Evaluate and app^ in detemuxung risks associated with disposal -and use Extend multimedia. modeling capabilities range of exposure and list FVovide materials Resource C o rivers at ID n Challenge Advance the concepts, understanding and acceptance oft he Support Tool Evaluate biological performance What is the fate and impact of placing novel conventional landfills 1 Evaluate long-term liners/covers to improve peuonuance and extend service life of landfills Develop methods for measuring selected ccarrtamiiiards in environment matrices -* What aie the Metrics for Sustainabiliy in land use planning Advance the Hie impact of and other factors at Brownfield Sites Assessment ofthe eiwrtorinierital consequences of the use of lloHuimafcsHal* t Evaluation of the properties of afi&ct fate, transport fs-a.lj.rjlyr cuid i , " ' - request and apply research . to manage materials streams, conserve resources and address emerging materials Figure 6.

NRMRL's ground water and sediments research include treatment/management options that are energy efficient compared to conventional alternatives. For example, capping and in situ treatment (including MNR) of contaminated sediments are low-energy alternatives to dredging and transport to a disposal facility. Similarly, some in situ treatments for ground water are more energy-efficient than pump & treat. ETSC and GWTSC provide site-specific assistance for RCRA Corrective Action sites (NRMRL).

Improving our ability to accurately predict waste constituent leaching, for a variety of waste types in a variety of waste management unit environments, is a critical RCRA and CERCLA program need. Tailored leach-testing field validation of Kosson protocol (from pilot) OSW has this underway. Report of field data comparisons with laboratory leach tests (NRMRL 07-165); synthesis report on evaluation of leaching procedures and limitations (NRMRL 08-132). The ongoing work isn't specific to waste-derived products but would be applicable for contaminant aqueous mobility. NRMRL awarded a FY06 pilot proposal for leach testing and modeling to assess beneficial use (leaching pathway only). NRMRL 's ongoing research on applying the Kosson protocol to coal combustion residues is being funded from the Hg MYP: Capstone report on fate of Hg and other metals from management of coal combustion residues (HG 06-91) Report on the potential formation of organo-mercury from anaerobic decomposition of CCRs (HG 07-62) Report on fate of toxic metals from land disposal and commercial use of CCRs from plants equipped with multipollutant control technologies (HG 08-42). 80 ------- Sustainability Research to better understand "green chemistry" approaches to identify environmentally friendly substitutes, especially for the 30 highest priority chemicals (from a listing of persistent, toxic, and bio-accumulative chemicals) Research into design of environmentally friendly products Development of source reduction opportunities for other hazardous wastes (e.g., combusted wastes, metals finishing) Industrial alternatives to/for priority chemicals (from pilot) NRMRL conducts green chemistry research under Goal 5. The MYP is currently being revised. NRMRL was awarded a pilot project for lead to identify which priority chemicals should be targeted for reduction. Beneficial Use Evaluating the stability, expected releases, and bioavailability of constituents in waste-derived products. Such products contribute to consumer exposures as well as to non-point source pollution of air and watersheds. OSW repeatedly receives queries on waste-derived products, and research and tests on these uses would help with the evaluation of any risks associated with them. Predictive analysis of expected releases could be verified through field monitoring (in a manner analogous to NERL's current research on the environmental fate of personal care products and pesticides). Major examples of waste derived products, a.k.a. "beneficial reuses" include road bed materials (asphalt), cement additives, frit, and CCA-treated wood. Aspects of leaching research are related to this, particularly the leaching research on materials that are applied to land (e.g., roadbed, fill).

See individual topics for products that can be incorporated into guidance materials. 87 ------- Appendix B: Legislative History Legislation under the Resource Conservation and Recovery Act (RCRA), and the Superfund Amendments and Reauthorization Act (SARA) in 1986, authorized research programs to support scientific needs. The Solid Waste Disposal Act of 1965 was the first law to require safeguards and encourage environmentally sound disposal methods for household, municipal, commercial, and industrial refuse. Congress amended this law in 1970, the Resource Recovery Act, and again in 1976, with the Resource Conservation and Recovery Act. Congress revised RCRA in 1980 and 1984. The 1984 amendments, the Hazardous and Solid Waste Amendments (HSWA), significantly expanded the scope of RCRA. The major subtitles are as follows: 1. Subtitle C establishes a program for managing hazardous waste from generation to ultimate disposal, including the cleanup of sites contaminated by hazardous waste spills and other releases to the environment. 2. Subtitle D establishes a program for managing solid (primarily nonhazardous) waste, such as household waste. Section 6902 of RCRA (42 USC 82 Subchapter I, Sec. 6902 (a)) describes the intent of Congress to promote the protection of health and the environment and the role of research by: 3. "Promoting a national research and development program for improved solid waste management and resource conservation techniques, more effective organizational arrangements, and new and improved methods of collection, separation, and recovery, and recycling of solid wastes and environmentally safe disposal of non-recoverable residues; and 4. "Promoting the demonstration, construction, and application of solid waste management, resource recovery, and resource conservation systems which preserve and enhance the quality of air, water, and land resources. RCRA as amended by HSWA has led to significant regulatory programs for the safe management of hazardous and non-hazardous wastes. The Agency is increasingly focusing on improvements to the regulatory framework based on the most current science and greater emphasis on resource recovery. In addition, legislation mandates that EPA require the investigation and cleanup, or remediation, of these hazardous releases at RCRA facilities. This program is known as RCRA Corrective Action (CA). EPA enforces RCRA CA primarily through statutory authorities established by HSWA. Legislative History Superfund, Oil Spills, VST The assessment and cleanup of sites contaminated with hazardous substances, fuels, or oils are often complex processes, with both the variety and number of sites making cleanup costly and time-consuming. For Superfund, the National Priorities List (NPL) presently lists 1,232 sites and an estimated 40 new sites will be added annually through at least 2010. There are more than 300,000 LUST CA sites, and States spend nearly $2 billion annually to clean up these sites. Additionally, it is estimated there are potentially hundreds of thousands of old gas stations that may require remediation. Annually, 18,000 to 24,000 oil spills are reported, and 10-25 million gallons of oil are spilled, impacting coastal and inland waterways. 88 ------- Contaminated sites under Superfund authority are addressed under provisions of the National Contingency Plan (NCP) (http://www.epa.gov/superfund/contacts/ntlcplan.htm) and related guidance documents (http://www.epa.gov/superfund/action/guidance/index.htm). Remedial actions follow a stepwise process from site discovery, through site assessment, through cleanup, to operation and maintenance and 5-year review. Removal actions are used when risks warrant near-term action. Through ORD, EPA has been conducting research to support the needs of the Superfund Program since the inception of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), also referred to as Superfund. ORD's Superfund research program was not formalized, however, until 1986 with the passage of the Superfund Amendments and Reauthorization Act (SARA). SARA established an alternative or innovative treatment technology research and demonstration program at EPA and authorized EPA to conduct and support hazardous substance research with respect to the detection, assessment, and evaluation of the effects on and risks to human health of hazardous substances and detection of hazardous substances in the environment. Oil spills are also addressed under provisions of the National Contingency Plan via a 3- pronged approach of prevention, preparedness, and response (http://www.epa.gov/oilspill/overview.htm). Research addresses the latter two aspects of the program. Corrective action for LUST sites is largely delegated to States and implemented by regulations with related guidance. In general, the process for leak response is to stop the release, report it, manage immediate risks, and then determine short- and long-term responses needed for cleanup. Brownfields redevelopment, part of EPA Strategic Goal 4, benefits from the characterization and remediation research described in this MYP. Research is authorized under the Small Business Liability Relief and Brownfields Revitalization Act, but an appropriation for research has not been requested. Instead, the Office of Brownfields Cleanup and Redevelopment works directly with ORD staff to identify high-priority research for funding via intra-agency funding transfer. This process is conducted by Goal 3 research staff to ensure coordination and prevent duplication of effort. 89 ------- Appendix C. EPA Strategic Plan and Land MYP Linkages EPA's Strategic Plan sets overall goals and specific targets for programs to achieve. The Land Goal within the strategic plan identifies the targets for the research programs that this MYP supports. The targets help us determine the appropriate sub-objectives where ORD can contribute to supporting the goals. Three objectives within Goal 3 address the OSWER programs. The goal states: Objective 3.1: Preserve Land. By 2008, reduce adverse effects to land by reducing waste generation, increasing recycling, and ensuring proper management of waste and petroleum products at facilities in ways that prevent releases. Sub-objective 3.1.1: Reduce Waste Generation and Increase Recycling. By 2008, reduce materials use through product and process redesign, and increase materials and energy recovery from wastes otherwise requiring disposal. Sub-objective 3.1.2: Manage Hazardous Wastes and Petroleum Products Properly. By 2008, reduce releases to the environment by managing hazardous wastes and petroleum products properly. Objective 3.2: Restore Land. By 2008, control the risks to human health and the environment by mitigating the impact of accidental or intentional releases and by cleaning up and restoring contaminated sites or properties to appropriate levels Sub-objective 3.2.1: Prepare for and Respond to Accidental and Intentional Releases. By 2008, reduce and control the risks posed by accidental and intentional releases of harmful substances by improving our Nation's capability to prepare for and respond more effectively to these emergencies. Sub-objective 3.2.2: Clean Up and Reuse Contaminated Land. By 2008, control the risks to human health and the environment at contaminated properties or sites through cleanup, stabilization, or other action, and make land available for reuse. Objective 3.3: Enhance Science and Research. [The purpose of this objective is to meet the science and research needs of OSWER. Specifically, the objective is as follows:] Through 2008, provide and apply sound science for protecting and restoring land by conducting leading-edge research and developing a better understanding and characterization of environmental outcomes under Goal 3. Two sub-objectives further differentiate between science and research: Sub-objective 3.3.1: Provide Science to Preserve and Remediate Land. Through 2008, provide sound science and constantly integrate smarter technical solutions and protection strategies that enhance our ability to preserve land quality and remediate contaminated land for beneficial reuse. Sub-objective 3.3.2: Conduct Research to Support Land Activities. Through 2008, conduct sound, leading-edge scientific research to provide a foundation for preserving land quality and remediating contaminated land. Research will result in documented methods, models, assessments, and risk management options for program and regional offices, facilitating their accurate evaluation of effects on human health and the environment, understanding of exposure pathways, and implementation of effective risk-management options. Conduct research affecting Indian country in partnership with tribes. 5 2003-2008 EPA Strategic Plan, September 2003, EPA-190-R-03-003, http://www.epa.gov/ocfo/plan/2003sp.pdf 90 ------- Table C-l shows where ORD research activities conducted under Objective 3.3 support sub-objectives under Objectives 3.1 Preserve Land and 3.2 Restore Land. It is not the intent of the research program to support each Goal 3 sub-objective. However, the program is leveraged with research conducted under other goals. Sub-objective 3.1.1 is primarily OSW resource conservation and waste reduction activities. The research activities supporting 3.1.1 are resource conservation and, under Goal 4, sustainability research, which addresses various areas of reuse, green chemistry, and life cycle assessment. The activities of OSW and OUST on management of hazardous waste, Sub-objective 3.1.2, is supported by research on waste management, multimedia modeling, and leaking underground storage tanks (LUST) fate and transport (F&T) studies and research on effectiveness of remedial alternatives. OSWER emergency response activities for oil and chemical spills and homeland security, under sub- objective 3.2.1, are supported by research on preparedness and response responsibilities with respect to risk assessment, F&T, site remediation, and risk management strategies for petroleum and non-petroleum oil spills. Homeland security research, conducted under Goal 4, also supports response activities through research on rapid risk assessment, water security, and decontamination of buildings. The Superfund program is addressed in Sub-objective 3.2.2. ORD research to support Superfund is primarily focused on contaminated sediments, ground water, site characterization, and site-specific technical support. Within EPA's Goal 4, ORD's human health risk assessment research produces exposure factors, toxicity values (IRIS), site- specific technical support, and conducts major risk assessments to support OSWER.

Matrix of Land MYP and Other MYP Research Areas Versus Media 92 ------- Appendix D. EPA Science Advisory Board Reviews EPA Science Advisory Board Review of Contaminated Sites and RCRA Multi-Year Plans Specific panel recommendations and the EPA response are presented below. SAB Recommendation EPA Response The Panel supports ORD's plan to merge the documents into a single plan that clearly relates the research to the Agency's strategic goals and targets. By clearly linking research priorities and the Agency's strategic objectives with defined long-term goals, themes, and work products, the Agency will be able to demonstrate the relevance, quality, and contribution of the individual research activities to meeting the Agency's mission within resource constraints. The Multi-Year Plan (MYP) merges the two former MYPs on contaminated sites and RCRA. Linkages to client outcomes are described in the logic diagram (Figure 3) and in the development of client-oriented long-term goals (LTGs). The Panel recommends that the revised, integrated plan address the difficult question of how short-term research, long-term research, core research, and problem-driven research will be integrated to support the Strategic Plan's Goal 3 strategic targets. A matrix (Appendix C, Figure C-l) in the MYP presents risk assessment/risk management categories versus media (e.g., soil, surface water) to highlight the focus of the Land MYP and leveraging and collaboration with other MYPs, which include core and problem-driven research. The Panel also recommends that the revised plan show how the various research activities connect to the Strategic Plan's Goal 3 targets. The Panel believes that a specific and transparent mapping of the elements of the Multi-Year Plan to the substantive goals of the Strategic Plan will improve the Multi-Year Plans and will optimize the use of scarce research dollars. Table C-l in the MYP shows the relationship of Strategic Plan Objective 3.3 Science and Research activities with activities in Objective 3.1 and 3.2 and their sub-objectives. Leveraging and coordination with research in other goals is important to address issues under Goal 3 in the Strategic Plan. These LTGs should be rewritten to be outcomes oriented rather than output oriented. The distribution of science and technical research activities by media, which is useful to OSWER, could be accomplished at the annual performance goal level. The six LTGs in the previous MYPs were condensed into two client-oriented LTGs in the revised MYP. Research activities by media are presented as research themes under each LTG. The Panel also recommends that the Agency implement a clearly defined institutional process of continuous re-scoping to regularly identify and prioritize emerging research topics, as discussed in the response to Charge Questions le and 2a. The MYP instituted an enhanced process to incorporate regional and program office research needs. Within the portfolio of projects identified in the RCRA and Contaminated Sites MYPs, the Panel believed there were clear opportunities for Table 1 in Section 5.2 lists research areas that are enhanced, decreased, or eliminated. Collaboration activities continue to be very 93 ------- efficiencies by combining some programs, reducing expectations in other programs, and reducing or eliminating other programs where clear leveraging opportunities with other government or private agencies could be identified. important to the research program and are presented in Appendix H of the MYP. Of note are an MOU with NIEHS and contaminated sediments collaboration activities with the Navy, Army Corps of Engineers, and EPA. The Panel recommends that the Agency continue to improve the annual performance measures to better reflect the intended/expected outcomes of ORD's efforts in supporting the Agency's strategic targets. This is an ongoing process in which annual performance goals (APGs) are being focused on the intended use of the supporting research. The Panel recommends that ORD establish a line item in its annual research budget that specifically supports research that looks far ahead (10+ years) on emerging needs, ideally through new resources but by re-programming if necessary. The Land MYP discusses leveraging its research program with other MYPs to evaluate emerging issues. In FY08, ORD re-directed research to initiate enhanced research efforts in nanotechnology. Mining will have an increased emphasis. The Panel recommends that the flow diagrams more clearly and succinctly illustrate the connections between the Strategic Plan, long- term goals, annual performance goals, and annual performance measures. We are addressing an effective way to diagram the connection of research products to support goals stated in the Strategic Plan. Wiring diagrams for each LTG show APGs supporting each LTG. Table D-2. Land Research Program: Summary of BOSC Recommendations from March 2006 Final Report and Proposed ORD Actions Timelines (March 2007) (includes entries only for those recommendations that require ORD action) Recommendation ORD Action Timeline for Action (la) How the MYP could communicate information more clearly Addressed in revised MYP; Sections 1 and 2 were streamlined, and the removed text was added to the Appendices. Final MYP (Ib) How future conditions can be better anticipated We will continue to use Regional Advisory Workgroups, Technical Support Centers, and communication with OSWER management to assist us in being aware of future issues that require research activity. Report progress at BOSC mid-point review (Ic) How collaborative efforts can be pursued with greater effectiveness, and how certain historical program needs are In 2006, we formed a group of federal agency program directors from NIEHS, DOE, Ongoing 94 ------- addressed as programs sunset or are terminated NSF, SERDP, and EPA to further document collaboration and limitation of the duplication of research. (2a) Improve the readability of the report by highlighting the essential features of the LandMYP and minimizing jargon and acronyms. Consider rephrasing the two LTGs to reflect technical or scientific themes inherent in ORD efforts to enhance the success of OSWER programs in Land Preservation and Restoration. Disagree on rephrasing LTGs. LTGs were rewritten in the draft in response to SAB and OMB recommendations to have them be outcome-oriented LTGs. Research questions, with scientific themes, will be stated when research themes (e.g., ground water) are discussed. Final MYP (3a) Consider including periodic forecasting of emerging problems that could be examined in a preliminary way to judge their import. The RCT, regional groups, Technical Support Centers, and OSWER management bring forward emerging issues (e.g., vapor intrusion into homes, ground water- surface water contamination, Brownfields, and animal carcass disposal. ORD shifts the research program to address the issues. In addition, the MYP will attempt to highlight emerging issues that are part of the research program. Final MYP (4a) Consider opportunities for collaboration and leveraging at the national and international levels. Enhance the use of Web-based support systems for facilitating multifacility research efforts. Look for opportunities to collaborate with EPA research efforts in Homeland Security and in risk communication. See answer to l(c). ORD is developing Web pages for each NPD, and we will have further discussion with the Superfund office on linking into their Web and communication systems. Report progress at BOSC mid-point review (So) The MYP should address the current and future processes for replacing retiring expertise and developing new scientists with emphasis on emerging areas. Increase support of university-based research to involve these stakeholders and train future generations of environmental researchers. This is not the purpose of a MYP. The ORD grants and fellowships programs in NCER address this issue by helping to develop the next generation of environmental scientists and engineers. ORD workforce planning is Done 95 ------- conducted principally by the labs and centers. (6a) If there are recognized gaps associated with sunsetting or terminating programs, these could be prioritized for collaborative research efforts. Text was added to the MYP in Sections 5.0 and 5.2 to address this comment. Final MYP (7a) The Subcommittee acknowledges the interplay of forces regarding performance metrics but endorses their continued use and suggests that the need for balance be borne in mind. Agree. The PART for this program was completed in 2006, and the negotiated measures will be incorporated into the management of the program. Done (8a) Outcomes. Consider how the linkages could be made more clear or enhanced in the Land MYP. Wording will be edited in the logic diagram, and PART measures will be added to the MYP. Section 3 was added on recent outcomes, and performance measures are stressed in the MYP. Final MYP (9a) Consider how to characterize and communicate uncertainties inherent in assessment methods and models. Explore collaborations with ORD efforts that focus on the analysis and communication of uncertainty. Integrate this information into Agency guidance and rules. Characterization and communication of uncertainties in risk assessment is a research area that cuts across many ORD research programs in addition to the Land program. For this reason, research aimed at characterizing and representing uncertainty in risk assessment is currently included under the Human Health Risk Assessment Research Plan. This happens to be a topic of substantial interest to the Assistant Administrator for ORD, Dr. George Gray, who has personally conducted significant research in this area in his previous career. There are thus several efforts currently underway within the HHRA Research program that will address this topic in a manner suitable for integration into Agency guidance and rules. Ongoing; primarily in HHRA MYP 96 ------- (Al) State the goals and objectives of the Program in terms of their short-term or long-term nature. Long-term and annual measures from the PART will be incorporated in the MYP. APGs in the MYP vary on the basis of the long- term or short-term nature of the science being addressed. Final MYP (A2) Articulate the benefits of the Land Research Program within the Land MYP by mapping the goals and activities within the Land MYP to the customer's performance measures. Recent benefits of the program are listed in Section 3. The MYP will link research activities to program office research needs, EPA Strategic Plan Goal 3 strategic targets, and Land Research Program PART measures. Final MYP (A3) Clarify within the Land MYP who is meant by stakeholders and clients. This comment is addressed in the final MYP. Final MYP (A4) Identify gaps not being covered by existing projects and the intersections among the projects. Such a gap analysis will position the Program to respond rapidly to circumstances where additional resources or leveraging opportunities present themselves. To better communicate the types of research conducted under this research plan and to demonstrate how leveraging occurs among ORD MYPs, a matrix was placed in the MYP (Appendix Figure C-l) to present Land MYP and other ORD MYP research areas (e.g., human health effects, remediation technology) versus media (e.g., soil, ground water) to highlight the focus of the Land MYP and collaboration with other MYPs. Also, a gap analysis is embedded in Appendices A and B of the MYP. Done (AS) Emphasize to a greater degree within the Land MYP how and by what means the outputs and products generated from the Land Research Program will be transferred to the field. This includes placing greater emphasis on transferring technologies to the private sector so that they can come into more common use and have greater impact. This may be beyond the purpose of a MYP. Additional efforts to enhance communication of research products involving linkage of line management to wider communication mechanisms are underway. Report progress at BOSC mid-point review (Bl) Provide greater description of how A high degree of detail was Final MYP 97 ------- criteria were used to prioritize needs and projects for both LTGs, but specifically for LTG2. provided on regional criteria and the process of utilizing regional workgroups for LTG1. ForLTG2, OSW, the customer, utilized a category 1, 2, and 3 process that was described in the MYP. We'll look at this comment in the revised MYP, but it is likely that readability and flow issues will prohibit us from adding more detail. (B2) Incorporate input from outside groups (other government agencies, academia, industry, and other stakeholders), especially for future Land MYPs, and ensure that all valid scientific advice is heard and considered apart from policy issues. The EPA conducts more peer review of their research programs than any other federal agency. When the MYP is final, it will be publicly available on the Web. The subcommittee was provided with the various levels of peer review that are already incorporated into the program. Done (B3) Articulate the mechanisms for ensuring periodic quality reviews during the conduct of projects. Such periodic (e.g., quarterly or annual) review and feedback are important for both ensuring that research is on track technically and for feedback from the customer. Where relevant, it may be appropriate to include the customer (e.g., regional staff, state agencies) in the process of obtaining periodic feedback. A formal annual review with clients has been in place since the inception of the research coordination team. Since the BOSC review, we have committed to semiannual topical progress reviews with clients, using the regional research advisory workgroups. Report progress at BOSC mid-point review (Cl) State the Program goals more clearly in terms of their scientific research focus. The goals could be recast in terms of the two major environmental challenges with problems, and the scientific advancements needed to aid their resolution then described as subgoals. Projects and outputs could be organized by major problems (e.g., assessment and cleanup of DNAPLs in ground water, design and operation of landfill bioreactors) along with the planned workflow. In working to prepare for the PART, most of the MYPs shifted to customer-focused LTGs instead of a scientific research focus. For each research theme (e.g., ground water contamination), we will state the scientific research focus for that theme in the MYP. Final MYP (C2) Review potential needs related to Cross-cutting issues are Done 98 ------- current issues that cross-cut multiple programs (e.g., biosolids and animal waste application to land, mining and megasites, oil and gas operations, infectious disease agents, beneficial reuse of waste materials, uncertainty in risk assessments, and communication of risk results. typically assigned to a particular MYP with an understanding of which other MYPs include related work. For example, land application of waste is conducted under the Water Quality MYP but is of interest to OSWER. Beneficial use of wastes is in the Land MYP, but the sustainability program contributes results as well. In the 2003 editions of the MYPs, we attempted to cross-reference outputs that addressed multiple programs. It proved impractical to maintain the cross-references as the programs evolved because of changing priorities and resources. Within the labs and centers, Assistant Directors routinely consult each other and relevant staff and management on synergies between various research programs and bring that information back to the various research coordination teams. (C3) Clarify in the Land MYP the sequence of research questions along a timeline and the activities that are to be conducted. The text in Section 5 of the document has been edited to clarify the progression of research. Wiring diagrams are updated. The reorganization of the Land APMs and APGs will also assist in presenting the timeline of research (see the response to Cl). Final MYP (C4) Identify, to the extent they exist, the opportunities for staff scientists or engineers to initiate ideas, for example, through a seed funding program. Most of the laboratories have an independent research program in which P.Is compete for seed funding. Done (Dl) Consider leveraging and collaborating with others so as to ensure The transition of half of the LTG 2 program to Final MYP 99 ------- timely progress for LTG 2. (D2) Improve the process for updating Integrated Risk Information System (IRIS) values for chemicals currently in the database and for developing values for potentially important chemicals not in the IRIS database. The Subcommittee recognizes that this falls only partially within the domain of the Land Research Program. (D3) Articulate how planned and future research programs support decision nanomaterials will be leveraged with other federal programs. The MYP will present a smaller focused materials management program. The IRIS is guided under LTG 1 of the Human Health Risk Assessment (HHRA) Research Program and is not a part of the Land Research Program. It is recognized that IRIS is a cross-cutting Agency database of interest and relevance to many ORE) research programs. The IRIS program is currently undergoing a period of significant revision, with the aim of increasing the transparency and inclusiveness of the IRIS chemical evaluation process, including formal, quantitative uncertainty analysis in IRIS assessments, and developing guidance for incorporating uncertainty analysis into decision making. There is a tradeoff to be made in that more transparency and consideration of uncertainty inevitably results in more time needed to complete assessments and, hence, delays the development of values for potentially important chemicals not within the IRIS database. However, ORD is committed to increasing the availability of current, scientifically rigorous chemical toxicity information within the IRIS database. Brownfields research activities will address Addressed in HHRA MYP Final MYP 100 ------- making on sustainability issues and on life cycle assessment determinations related to solid and hazardous waste management. sustainability issues; however, the shift to nanotechnology will reduce the research program activities in hazardous waste management. (D4) Update key technology documents related to landfill design. ORD could collaborate with the geosynthetic industry to help fund such work. Final MYP (D5) Identify within the Land MYP the mechanisms for tracking progress for specific projects with respect to the LTGs. The ORD management has quarterly reporting for progress toward completing APMs and APGs which lead to addressing LTGs. These reports are forwarded to NPDs and the DAA for Management. Management is held accountable for completing scheduled milestones. Ongoing (El) Identify a process for acquiring or developing key leaders for those programs where clear leadership may be lacking. Such leadership should be reflected in personnel as well as programs. Particular emphasis should be given to leadership in emerging fields. ORD has a hiring process in place to add senior scientists to lead emerging or high priority research areas. Done (E2): Describe or develop mechanisms for identifying mature research fields, emerging issues, and/or ensuring that the ORD-planned research is not duplicating efforts being conducted by other government or state agencies or by private industry. This could be guided by external peer review by experts drawn from universities, nongovernmental organizations, state agencies, and private industries. This is an ongoing issue that we will continue to address. Addressing customer research needs, collaboration of research efforts, and limiting duplication of research are always of concern in this research area (see responses to Ic and 3a). ORD, in its response to the BOSC subcommittee, provided examples from regional site managers on the specific benefits of applied research. Final MYP (E3) Enhance ORD'sposition as a global leader by encouraging continued participation in international panels and meetings. Agree. Done (E4) Ensure that funding is directed Agree. The shift to Final MYP 101 ------- toward areas in which large gains in understanding can be made through research. This involves favoring research areas that are new or emerging over mature areas of research. The Subcommittee recognizes the balance that must be struck between new research and technical assistance. nanomaterials, in part, addresses this comment. This is a problem-driven research program in which importance is placed on addressing customer research needs. Every year, new issues are brought forward (e.g., vapor intrusion into homes, ground water-surface water contamination, Brownfields, animal carcass disposal), for which we shift the research program and partner with OSWER to address the issue. 102 ------- Appendix E: Research Conducted Under the Human Health Risk Assessment MYP and Related Research Risk assessment is a process in which information is analyzed to determine if an environmental hazard might cause harm to exposed persons or ecosystems (NAS, 1983). It is the essential intermediary means by which primary data and published literature are compiled, analyzed, and summarized for application to decision making in real-world situations. This science-based framework for decision making is central to EPA's implementation of its statutory responsibilities and to its mission to protect human health and the environment. The National Center for Environmental Assessment (NCEA) conducts a variety of risk assessments and risk assessment research in support of OSWER. Much of this research is described in the Human Health Risk Assessment (HHRA) Multi-Year Plan (MYP). This plan serves as a primary EPA mechanism to implement this process, linking laboratory and field science with the use of this information by EPA programs, regions and the broader community. To achieve this goal, the HHRA MYP directs efforts toward the following: Providing qualitative and quantitative health hazard assessments of priority environmental contaminants for incorporation in applied risk assessments, exemplified by the Integrated Risk Information System (IRIS) Toxicological Reviews and Summaries, reference doses (RfDs), reference concentrations (RfCs), oral cancer slope factors and inhalation cancer unit risks; Preparing Air Quality Criteria Documents (AQCDs) for criteria air pollutants as a mandated pre-requisite to EPA's review of National Ambient Air Quality Standards (NAAQS); Conducting environmental risk assessments of national importance, such as potential health impacts in the aftermath of the attack on the World Trade Center and the reassessment of the health risks posed by dioxin; Developing models, methods and guidance to incorporate the latest scientific advances into EPA risk assessment practice, thereby maintaining the scientific quality and objectivity of EPA assessments consistent with the state-of-the-science; Identifying, evaluating, and conveying to the scientific community any key uncertainties and research needed to improve health risk assessments through laboratory, field, and methods research; and Supporting the Risk Assessment Forum (Forum), through which risk assessors across the Agency can communicate and harmonize risk assessment practices to facilitate a consistent and predictable framework for EPA activities. The core of the HHRA activities is the IRIS, which began two decades ago as an internal EPA activity to facilitate communication among ORD programs and regions to harmonize the otherwise disparate reference values prepared for hazardous substances in different parts of the Agency. IRIS has since grown to be the premier national and international source for quantitative risk values and environmental pollutant health hazard information. A typical IRIS 103 ------- Toxicological Review and Summary provides a qualitative discussion and documentation of environmental health hazards posed by a substance to humans, accompanied by a reference dose (RfD), reference concentration (RfC), oral cancer slope factor (CSF), and/or cancer inhalation unit risk (IUR). OSWER risk assessors and policy makers apply these quantitative risk values to measured or estimated human dose levels to inform their decision making on environmental issues. Although nonregulatory, quantitative IRIS values influence many environmental decisions and may serve as a basis for additional regulatory consideration. The increased visibility accorded IRIS values has been accompanied by additional government and stakeholder scrutiny, leading to increased time required for document review and finalization. To facilitate more rapid responses to urgent programmatic needs on less controversial substances, the HHRA MYP also guides the production of Provisional Peer-Reviewed Toxicity Values (PPRTVs) for internal used by OSWER and the regions when IRIS values are not available. Methods development work under the HHRA MYP is directed toward incorporating scientific advances into risk assessment practice, similar to equipment upgrades to maintain standards of practice. In order to achieve peer-review quality, these methods developments must respond to the increasing breadth and depth of available information across the diverse scientific disciplines contributing to risk assessment. To address this, the HHRA MYP has engaged in a process to determine the scientific foci most advantageous to advancing risk assessment science, based on projections of future Agency needs, scientific developments, and the availability of resources. These HHRA foci include mode of action, PBPK modeling, quantitative methods, inhalation methods, exposure measures, chemical mixtures assessment, and microbial risks. Many of these methods are applicable to risk assessment problems of interest to OSWER (e.g., assessment of risks associated with exposure to asbestos, and methods for quantifying dermal exposure). Technical support to customer programs and regions is a key component of all these HHRA activities, whether assessment production, methods development, guidance, or other outputs. This support is provided through both formal and informal channels. Formal technical support is provided through such means as the IRIS Help Desk, the Superfund Health Risk Technical Support Center, and the Ecological Risk Assessment Support Center. Where necessary, these support centers can access additional expertise from HHRA and other EPA scientists. Direct technical assistance is also provided by HHRA scientists to programs and regions that request regulatory or site-specific support. These efforts are tracked internally through the Programmatic and Regulatory Support Tracking System. More informal channels are also widely used to expedite assistance on less complex issues, testifying to the widespread use of HHRA products across the Agency and beyond. Within the purview of the HHRA Program Project, technical expertise is often transferred between projects in order to achieve program objectives. For example, Forum projects prepared under this MYP represent major Agency consensus documents requiring considerable technical and managerial input. A recent example of this is the "EPA Guidelines for Carcinogen Risk Assessment" document, developed through a cross-Agency effort including significant OSWER participation. 104 ------- Related Research Homeland Security Research Topics The ORD Homeland Security research program conducts research in the following areas: Safe Buildings: Sampling and analysis methods, containment, decontamination technology, residue disposal, exposure modeling, agriculture biomass, and structures and outdoor decontamination Water Infrastructure Protection: Sampling and analysis methods, decontamination technology, surveillance systems, exposure modeling, and water/wastewater treatment Threat and Consequence Assessment: Risk assessment methods and data, rapid risk assessment tools, threat analysis, and technical support. NCER-Related Research Several programmatically relevant research programs have been supported through the NCER's Science to Achieve Results (STAR) competitive grants program and the Small Business Innovation Research (SBIR) program. A new generation of cleaner industrial manufacturing and processing technologies is needed as it becomes increasingly clear that "end-of-pipe" pollution controls for industrial operations are not always a sufficient means of reaching avoidance/prevention goals. In collaboration with the National Science Foundation, NCER has provided funds for fundamental and applied research in the physical sciences and engineering to stimulate the discovery, development, and evaluation of advanced and novel environmentally benign methods for industrial processing and manufacturing. Nanotechnology has the potential to (a) develop new processing technologies that minimize or eliminate the use of toxic materials and the generation of undesirable byproducts and effluents and (b) develop materials to replace current hazardous constituents, resulting in reductions in energy, materials, and waste generation. NCER has funded a nanotechnology and nanomaterials research program encouraging proposals in areas in which theoretical foundations are sufficiently well established to allow practical applications to be addressed. Because nanomaterials can have a potentially harmful effect on human health and the environment, NCER has also funded research to address these concerns, including the toxicology of manufactured nanomaterials, their environmental fate and transport, bioavailability, and exposure pathways for humans. Small Business Innovative Research (SBIR) Successful Products EPA is one of 11 federal agencies that participate in the SBIR program. The two-phase structured program seeks to document the feasibility of the proposed technological concept in Phase 1 and to commercialize the technology in Phase 2. NCER has issued a number of SBIR 105 ------- solicitations, including research for Pollution Prevention, Nanomaterials, Waste Management and Site Remediation, Hazardous Waste Monitoring, and Solid Waste Recycling.

Summary information on EPA collaboration with federal agencies and state groups is presented in Appendix C by topic area. The research topics and associated collaborative activities and products show the degree of collaboration and leveraging of technical expertise across the federal government on restoration and preservation issues. Collaborative research efforts of note involve coordination of the unique controlled-spill field research facility, which was designed in cooperation with the U.S. Bureau of Reclamation. Geophysical research experiments and development of software for subsurface characterization and detection of contaminants are being conducted with the U.S. Geological Survey (USGS) and DOE's Lawrence Berkeley National Laboratory. USGS also has a number of programs, such as the Toxic Substances Hydrology Program, that support studies related to contamination of surface water and ground water by hazardous materials. EPA also conducts collaborative laboratory research with DOD, DOE, DOI, and the National Aeronautics and Space Administration (NASA) to improve characterization and risk management options for dealing with subsurface contamination. The DOD SERDP supports research on various remediation topics (http://www.serdp.org). The EPA and DOE work with DOD on the SERDP Council, Executive Working Group, and various technical panels. The technical panels work together to identify research needs and evaluate proposals. The Agency is also working with the NIEHS, which manages a large basic research program focusing on Superfund issues, to advance fundamental Superfund research. The ATSDR also provides critical health-based information to assist EPA in making effective cleanup decisions. EPA ORD has formal memoranda of understanding (MOUs) with each of these agencies on collaborative projects, information exchange, and identification of research issues. The Interstate Technology Regulatory Council (ITRC) has proved an effective forum for coordinating federal and state activities and for defining continuing research needs through its teams on topics, including contaminated sediments, permeable reactive barriers, radionuclides, and Brownfields.

Superfund Health Risk Technical Support Center Contact: Jon Reid, 513-569-7375 The Superfund Health Risk Technical Support Center (STSC) supports regional and headquarters Superfund risk assessors by reviewing and developing exposure and toxicity factors that allow more accurate quantitative estimates of risk to be developed. Much of the activity is focused on developing new and updated peer-reviewed provisional toxicity values that describe dose-response toxicological relationships. External peer review of the provisional toxicity values was initiated in FY 1999. The Center also provides user support through the STSC Hotline as well as on-site expertise reviews. All assistance is provided on a rapid turnaround basis. 117 ------- Ecological Risk Assessment Technical Support Center Contact: Michael Kravitz, 513-569-7140 The Ecological Risk Assessment Support Center (ERASC) will provide technical and management support and arrange for scientific review and consistency on topics relevant to ecological risk assessment and ecological concerns. NCEA will manage the Center, but it is understood that it will routinely be necessary to access the expertise that is located in various ORD laboratories and centers. The Center Director will arrange for this access as appropriate. During the FY01 pilot program, an Implementation Committee consisting of members from the Office of Research and Development, the Office of Solid Waste and Emergency Response, and EPA regional offices will provide oversight and guidance for formation of the ERASC and its guiding principles. Science and Technology Liaisons Coordinator: Ken Sala, 202-564-1567 This program provides ORD representatives to regions to support regional integration of technology and coordination with ORD. STL's mission is to enhance interactions of the EPA regional offices with ORD and with other organizations involved in environmental research and technical support (including its funding, development, and application), with specific emphasis on OSWER Program (Superfund/RCRA/FF/UST/Solid Waste) issues, thereby facilitating the use of sound science and engineering in EPA decisions and actions.
