Environmental Management
Science Program (EMSP):
Research Related to Subsurface Contamination in the Vadose and Saturated Zones

The Offices of Science (SC) and Environmental Management (EM), U.S. Department of Energy (DOE), hereby announce their interest in receiving proposals to support specifically innovative, fundamental research to investigate DOE subsurface contamination in the vadose and saturated zones.

SUPPLEMENTARY INFORMATION: The Office of Environmental Management, in partnership with the Office of Science, sponsors the Environmental Management Science Program (EMSP) to fulfill DOE's continuing commitment to the cleanup of DOE's environmental legacy. The program was initiated in Fiscal Year 1996, to (1) address long-term technical issues crucial to the EM mission, and (2) provide EM with near-term fundamental data critical to the advancement of technologies that are under development, but not yet at full scale nor implemented. Proposed basic research under this announcement should contribute to environmental management activities that would decrease risk for the public and workers, provide opportunities for major cost reductions, reduce time required to achieve EM's mission goals, and, in general, should address problems that are considered intractable without new knowledge.

This program is designed to inspire breakthroughs in areas critical to the EM mission through basic research and will be managed in partnership with SC. The Office of Science's procedures, as set forth in the Office of Science Merit Review System, available at: http://www.science.doe.gov/production/grants/merit.html, and published in the Federal Register, March 11, 1991, Vol. 56, No. 47, pages 10244-10246, will be used for merit review of proposals submitted in response to this announcement.

Subsequent to the formal scientific merit review, proposals that are judged to be scientifically meritorious will be evaluated by DOE for relevance to the objectives of the Environmental Management Science Program. Additional information can be obtained about the general program at: http://emsp.em.doe.gov.

Purpose

Over the past 50 years, the United States created an industrial complex to develop, test, manufacture, and maintain nuclear weapons for national security purposes. The production and testing of nuclear weapons created a legacy of significant environmental contamination, ranging from uranium mining and milling, waste disposal, and radionuclide migration in ground water and soil. In 1995, the 104th Congress authorized creation of the Environmental Management Science Program (EMSP) to develop a long term, basic science infrastructure to focus on the environmental cleanup effort DOE began formally in 1989. To address the largest environmental cleanup program in the world, from a cost perspective, EMSP has the following objectives:

  • Provide scientific knowledge that will revolutionize technologies and cleanup approaches to significantly reduce future costs, schedules, and risks
  • "Bridge the gap" between broad fundamental research that has wide-ranging applicability, such as that performed in DOE's Office of Science and needs-driven applied technology development that is conducted in EM's Office of Science and Technology
  • Focus the Nation's science infrastructure on critical DOE environmental management problems

  • Since 1996, the Program has held six competitions and has awarded over $290 million in funding to 361 research projects. A breakdown of the EMSP awards by year is as follows:

  • 1996 and 1997: 202 awards totaling $160 million targeted at a broad spectrum of basic science cleanup and waste management issues
  • 1998: 33 awards totaling $30 million focused on high-level radioactive waste and decontamination and decommissioning issues
  • 1999: 39 awards totaling $30 million fostered basic research in the areas of vadose zone contamination and low dose radiation
  • 2000: 42 awards totaling $30 million in research renewals for 1996 and 1997 funded projects
  • 2001: 45 awards totaling $39 million focused on additional high-level radioactive waste and decontamination and decommissioning issues

  • Representative Research Areas

    Basic research is solicited in all areas of science with the potential for addressing problems in subsurface contamination and transport processes in the vadose and saturated zones. Processes and problems in the vadose zone constitute important subjects of concern to the Department's Environmental Management Program. Relevant scientific disciplines include, but are not limited to: geological sciences (including geochemistry, geophysics, hydrogeologic flow and transport modeling, process modeling, and hydrologic field-studies), plant sciences (including mechanisms of contaminant uptake, concentration, sequestration, and phytoremediation), chemical sciences (including fundamental interfacial chemistry, computational chemistry, actinide chemistry, and analytical chemistry and instrumentation), engineering sciences (including control systems and optimization, diagnostics, transport processes, fracture mechanics, and bioengineering), materials science (including other novel materials-related strategies), and bioremediation (including biogeochemistry; microbial science related to ex situ treatment of metals, radionuclides, and organics; and in situ treatment of organics). The Natural and Accelerated Bioremediation Research (NABIR) program in the Office of Biological and Environmental Research, Office of Science, may issue a Notice related to in situ treatment of metals and radionuclides during FY 2002. Research projects relating to this area should be submitted to NABIR rather than to EMSP. Additional information about the NABIR program can be found at: http://www.lbl.gov/NABIR/.

    SUBSURFACE CONTAMINATION RESEARCH NEEDS

    This research announcement has been developed for Fiscal Year 2002, with the primary objective of providing continuity in scientific knowledge that will revolutionize technologies and clean-up approaches for solving DOE's most complex environmental problems. An overview of EMSP vadose and saturated zone research needs is summarized in this section based on the National Academy of Sciences, National Research Council (NRC) report published in 2000 titled "Research Needs in Subsurface Science." NRC recommendations for basic research focus in four areas:

  • Location and characterization of subsurface contaminants and characterization of the subsurface
  • Conceptual modeling
  • Containment and stabilization
  • Monitoring and validation

  • More detailed explanations of the nature and extent of environmental contamination throughout the DOE Complex, particularly at the six largest Field Offices, and reference web sites, can be found in the background section of this Announcement. Interested proposers are referred to three web sites that provide information regarding subsurface contamination across the DOE Complex:

  • Subsurface Contamination Focus Area (SCFA) at: http://www.envnet.org/scfa/ provides new science technologies, approaches, and technical assistance to address soil and water pollution, reducing the risk and cost of cleanup and stewardship. Proposers are invited to review the SCFA Product Lines and Technical Targets; the later is under development to strategically guide research and technology products to end-users. A few of the critical research areas included in the Technical Targets are: characterizing and monitoring the lateral and vertical extent of dense nonaqueous phase liquids (DNAPLs) transport; reactive materials for barrier systems that maintain permeability over time; biogeochemical processes leading to the mobilization/immobilization of the contaminants in soils and sediments, as well as the those factors controlling their bioavailability; and monitored natural attenuation processes and validation strategies.
  • Idaho National Engineering and Environmental Laboratory lead an effort to develop a National Roadmap for Vadose Zone Science and Technology described at: http://www.inel.gov/vadosezone/ to improve vadose zone characterization and to monitor and simulate subsurface contamination fate and transport, integrating the saturated zone.
  • Idaho National Engineering and Environmental Laboratory's (INEEL) role as EM's Lead Lab is to ensure the integration of critical new science, technology, and programmatic solutions for cleanup and long term stewardship, described at: http://www.inel.gov/environment/em-lead.shtml.

  • There are about 6.4 billion cubic meters of contaminated soil, groundwater, and other environmental media at the DOE sites. Contaminants of concern across the Complex broadly include: radionuclides, metals, and dense nonaqueous phase liquids (DNAPLs). More specifically, key chemicals by group are:

  • Radionuclides: plutonium, strontium-90, cesium-137, isotopes of uranium, trituim, thorium, technecium-99, radium, and iodine-129
  • Metals: lead, chromium VI, mercury, zinc, beryllium, arsenic, cadmium, and copper
  • DNAPLs: carbon tetrachloride, trichloroethylene, dichloroethylene, tetrachloroethylene, chloroform, dichloromethane, and polychlorinated biphenyls

  • The life cycle costs for the Office of Environmental Management cleanup program have been estimated to be $147 billion between 1997 and 2070 (DOE 1998a). During this period of time, the EMSP research results can make a significant impact on reducing risks, costs, and cleanup schedules.

    Details of the programs of the Office of Environmental Management and the technologies currently underdevelopment or in use by the Environmental Management Program can be found at: http://www.em.doe.gov and at the extensive links contained therein. The programs and technologies should be used to obtain a better understanding of the missions and challenges in environmental management in DOE when considering areas of research to be proposed.

    Location and Characterization of Subsurface Contaminants and Characterization of the Subsurface

    The challenges of locating and characterizing subsurface contamination are magnified by the wide range of contaminant types; the wide variety of geological and hydrological conditions across the DOE complex; and the wide range of spatial resolutions at which this contamination must be located and characterized, from widely dispersed contamination in groundwater plumes to small isolated hot spots in waste burial grounds. Basic research is needed to support the development of the following capabilities to locate and characterize contamination in the subsurface and to characterize subsurface properties at the scales that control contaminant fate and transport behavior:

  • Improved capabilities for characterizing the physical, chemical, and biological properties of the subsurface
  • Improved capabilities for characterizing physical, chemical, and biological heterogeneity, especially at the scales that control contaminant fate and transport behavior. Approaches that allow the identification and measurement of the heterogeneity features that control contaminant fate and transport to be obtained directly (i.e., without having to perform a detailed characterization of the subsurface) are especially needed
  • Improved capabilities for measuring contaminant migration and system properties that control contaminant movement
  • Methods to integrate data collected at different spatial and temporal scales to better estimate contaminant and subsurface properties and processes
  • Methods to integrate such data into conceptual models

  • Conceptual Modeling

    Existing conceptual and predictive models have often proven ineffective for understanding and predicting contaminant movement, especially at sites that have thick vadose (unsaturated) zones or complex subsurface characteristics. Accurate conceptualizations are essential for under- standing the long-term fate of contaminants in the subsurface and the selection and application of appropriate corrective actions. Basic research explicitly focused on fundamental approaches and assumptions underlying conceptual model development could produce a toolbox of methodologies that are applicable to contaminated sites both inside and outside the DOE complex. This research should focus on the following topics:

  • New observational and experimental approaches and tools for developing conceptual models that apply to complex subsurface environments, including such phenomena as colloidal transport and biologic activity
  • New approaches for incorporating geological, hydrological, chemical, and biological subsurface heterogeneity into conceptual model formulations at scales that dominate flow and transport behavior
  • Development of coupled-process models through experimental studies at variable scales and complexities that account for the interacting physical, chemical, and biological processes that govern contaminant fate and transport behavior
  • Methods to integrate process knowledge from small-scale tests and observations into model formulations, including methods for incorporating qualitative geological information from surface and near-surface observations into conceptual model formulations
  • Methods to measure and predict the scale dependency of parameter values
  • Approaches for establishing bounds on the accuracy of parameters and conceptual model estimates from field and experimental data

  • The research needs outlined above call for more hypothesis-driven experimental approaches that address how to integrate the understanding of system behavior. This research will require expertise from a wide range of disciplines and must be conducted at scales ranging from the laboratory bench top to contaminated field sites. Moreover, to have long-term relevance to the DOE cleanup mission, this research must be focused on the kinds of subsurface environments and contamination problems commonly encountered at major DOE sites.

    Containment and Stabilization

    There has been an increasing emphasis on, and acceptance of, waste containment and stabilization in recent years, both in DOE and by regulatory agencies. Decreasing cleanup budgets, evaluations that show containment is a low-risk choice for some problems, and recognition that some contamination cannot be remediated either with current technologies or conceivable new technologies are responsible for this change in philosophy. However, at some sites, containment and stabilization may be an interim measure and has its own set of associated technical problems. There is little understanding of the long-term performance of containment and stabilization systems, and there is a general absence of robust and cost-effective methods to validate that such systems are installed properly or that they can provide effective long-term protection.

    The construction of stabilization and containment systems is properly within the province of applied technology development. However, basic research focused on the following topics will be needed to support this technology development effort:

  • The mechanisms and kinetics of chemically and biologically mediated reactions that can be applied to new stabilization and containment approaches (e.g., reactions that can extend the use of reactive barriers to a greater range of contaminant types found at DOE sites) or that can be used to understand the long-term reversibility of chemical and biological stabilization methods
  • The physical, chemical, and biological reactions that occur among contaminants, soils, and barrier components so that more compatible and durable materials for containment and stabilization systems can be developed
  • The fluid transport behavior in conventional barrier systems, for example, understanding water infiltration into layered systems, including infiltration under partially saturated conditions and under the influences of capillary, chemical, electrical, and thermal gradients can be used to support the design of more effective infiltration barrier systems
  • The development of methods for assessing the long-term durability of containment and stabilization systems

  • Monitoring and Validation

    Monitoring and validation are necessary at both the front and the back ends of the site remediation process. At the front end, monitoring and validation are used to support the development of conceptual and predictive models of subsurface and contaminant behavior. At the back end, monitoring and validation are used to demonstrate the effectiveness of efforts to remove, treat, or especially to contain contamination and to gain regulatory acceptance for such corrective actions. Moreover, such monitoring and validation efforts can also improve the understanding of the contaminant fate and transport processes and can be used to recalibrate and revise conceptual and predictive models — important elements of the model building process.

    The ability to monitor and validate is essential to the successful application of any corrective action to a subsurface contamination problem and regulatory acceptance of that action. However, the knowledge and technology bases to support these activities are not fully developed and are receiving little attention in EM's science and technology programs.

    Many of the research opportunities for monitoring and validation have been covered in the research emphases discussed above. Basic research is needed on the following topics:

  • Development of methods for designing monitoring systems to detect both current conditions and changes in system behaviors. These methods may involve the application of conceptual, mathematical, and statistical models to determine the types and locations of observation systems and prediction of the spatial and temporal resolutions at which observations need to be made
  • Development of validation processes. The research questions include (1) understanding what a representation of system behavior means and how to judge when a model provides an accurate representation of a system behavior—the model may give the right answers for the wrong reasons and thus may not be a good predictive tool; and (2) how to validate the future performance of the model or system behavior based on present-day measurements
  • Data for model validation. Determining the key measurements that are required to validate models and system behaviors, the spatial and temporal resolutions at which such measurements must be obtained, and the extent to which surrogate data (e.g., data from lab-scale testing facilities) can be used in validation efforts
  • Research to support the development of methods to monitor fluid and gaseous fluxes through the unsaturated zone, and for differentiating diurnal and seasonal changes from longer-term secular changes. These methods may involve both direct (e.g., in situ sensors) and indirect (e.g., using plants and animals) measurements over long time periods, particularly for harsh chemical environments characteristic of some DOE sites. This research should support the development of both the physical instrumentation and measurement techniques. The latter includes measurement strategies and data analysis (including statistical) approaches

  • BACKGROUND

    The DOE has a 50-year legacy of environmental problems resulting from the production of nuclear weapons. Migration of some groundwater plumes threaten local and regional water sources, and in some cases, have adversely impacted off-site resources. The Department is responsible for the remediation of numerous landfills at facilities. These landfills are estimated to contain over three million cubic meters of radioactive and hazardous buried waste, some of which has migrated to the surrounding soils and groundwater. Currently available cleanup technologies are inadequate or unacceptable due to excessive costs, increased risks, long schedules, or the production of secondary waste streams.

    Much of the defense-related contamination within the Department (the Complex has over 100 sites) occurs at six of the largest sites, as summarized below: Hanford, Washington; Idaho National Engineering and Environmental Laboratory (INEEL); Nevada Test Site (NTS); Oak Ridge Reservation (ORR), Tennessee; Rocky Flats Environmental Technology Site, Colorado, and Savannah River Site (SRS), South Carolina.

    Hanford Site, Washington

    Located in southeastern Washington State, Hanford encompasses 1450 square kilometers (km2). From 1940 to 1989, nuclear weapons production took place, leaving several production reactors, chemical separations plants, and solid and liquid storage sites. The unsaturated, or vadose zone, on the central plateau area is 60-90 meters (m) thick. Here, several trillion liters of contaminated water and supernatant liquid were discharged or gravity-settled via, basins, cribs, trenches, tanks, etc., causing ground water and soil contamination from radionuclides (primarily, tritium, uranium, cesium-37, strontium-90, technecium-99, and iodine-129), metals (e.g. chromium), and DNAPLs (e.g. carbon tetrachloride). Prior to the 1990s, it was thought that the sorption capabilities of the soil in the vadose zone would limit migration of radionuclides; however, recent conceptual and mathematical models indicate more rapid migration potential to the groundwater.

    The DOE created the Groundwater/Vadose Zone Integration Project, described at: http://www.bhi-erc.com/projects/vadose to coordinate cleanup activities at Hanford. A number of projects were awarded in the 1999 EMSP Vadose Zone research call that were highly relevant to science needs at the Hanford site. DOE/Richand has identified important, current scientific issues for research that are not being addressed by others at the Hanford site, or within the current EMSP program. Resolution of these issues would advance the state of remediation and site closure at Hanford and other DOE sites as well. These scientific issues may be found in a briefing document at: http://www.bhi-erc.com/projects/vadose/sandt/stdocs.htm. A 2001 report by the National Academy of Sciences, National Research Council titled "Science and Technology for Environmental Cleanup at Hanford" presents the successes and improvement areas of the science and technology program in the Hanford cleanup. Interested investigators are also referred to the Fiscal Year 2001, Subsurface Contaminations Technology Needs list at: http://www.pnl.gov/stcg/fy01needs/ss/index.stm for a detailed description of site research needs.

    Idaho National Engineering and Environmental Laboratory

    Located west of Idaho Falls, Idaho, INEEL occupies 2,300 km2 of semi-arid desert along the northern margin of the Eastern Snake River Plain. The site was established as a building, testing, and operating station for various types of nuclear reactors and propulsion systems. Spent fuel from the naval reactor program is also managed there. Low levels of plutonium have been found in ground water beneath the Radioactive Waste Management Complex (RWMC)–a disposal site that received low-level and transuranic waste beginning in 1952. Pit 9, a trench within the RWMC, received an estimated 7,100 m3 of sludge and solids contaminated with plutonium and americium. Similar to Hanford, at the time, the thick (60-240 m) unsaturated zone of volcanic strata was thought to impede contaminant migration to the underlying aquifers. Estimates today indicate travel times of tens of years, as opposed to estimates made in the 1950s and 1960s of thousand-year travel times. Interested investigators are referred to the INEEL Science and Technology Needs list at: http://www.inel.gov/st-needs for a detailed description of fundamental science studies that will assist, accelerate, or reduce the cost of cleanup.

    Nevada Test Site

    The NTS became the primary location for atmospheric and underground nuclear testing in 1951. The Test Site occupies 3,500 km2 of land in southern Nevada, north of Las Vegas about 143 km. Surface and shallow soil are contaminated with americium, plutonium and depleted uranium, and with metals from nuclear detonations, safety test shots, and rocket engine testing. Underground nuclear testing resulted in over 300 million curies of subsurface contamination including, tritium, plutonium, uranium, cesium, strontium, and other fission products. Tritium plumes have been detected from testing locations because this radionuclide is very mobile in the water phase. Plutonium, once thought to be relatively immobile in groundwater due to low solubilities and strong sorption on mineral surfaces, was detected 1.3 km downgradient of the Benham test on Pahute Mesa, in a 600-m-deep monitoring well. The plutonium was detected on colloids, leaving open the question of the contribution of colloidal transport of plutonium versus the prompt injection effects of the detonation blast. Basic research in the mechanical and geochemical transport of plutonium is warranted. Other site-specific technology needs can be found at: http://www.nv.doe.gov/programs/envmgmt/blackmtn/TDSTCGTechnologyNeeds.htm.

    Oak Ridge Reservation

    Located about 10 km west of Knoxville, Tennessee, ORR was built originally to produce and chemically separate plutonium. Later, ORR produced isotopes and conducted isotopic and hazardous constituents research. ORR has three main facilities: the Oak Ridge National Laboratory supported plutonium production research and development, and the Y-12 and K-25 Plants produced highly enriched uranium via magnetic separation and gaseous diffusion, respectively. Wastes from these activities were placed in burial grounds, that have subsequently caused soil and water contamination in the Melton Valley Watershed, including strontium-90, tritium, cesium-137, and cobalt-60. Seepage from flooding of the waste trenches caused downgradient migration of radionuclides. The sediments behind White Oak Dam are significantly contaminated with radionuclides; White Oak Creek drains Melton Valley and the surface water contains tritium. Basic research is needed to better locate and characterize contamination hot spots in the burial grounds, as well as to improve the site conceptual and mathematical models, which include fractured-bedrock flow and karst hydrology. Containment systems, such as caps and barriers, and performance monitoring of engineered systems will be constructed under the cleanup program to verify and validate long-term performance and model results. Investigators are referred to the Technology Needs Database at: http://www.em.doe.gov/techneed to review Oak Ridge's needs list in the areas of characterization, treatment, storage, and disposal of hazardous and radioactive wastes.

    Rocky Flats

    Rocky Flats Environmental Technology Site is located on the western side of Denver, Colorado, and encompasses 140 hectares. Operations ceased in 1989 after years of fabrication and components assembly for nuclear weapons production. Materials used in these activities included plutonium and enriched uranium metals and oxides. Poor storage and disposal practices resulted in surface and groundwater contamination on and offsite, principally, soil contamination with americium, plutonium, and uranium. Cleanup and closure actions include removal and stabilization of contaminated media, construction of caps and barriers, and long term monitoring and surveillance. Investigators are referred to the Rocky flats website at: http://www.aimsi.com/rockyflats/ to review science and technology needs, as well as related information.

    Savannah River Site

    The SRS was established in 1950 near Aiken, South Carolina, to produce radioactive isotopes for use in nuclear weapons production. Encompassing 800 km2, the Site contains production reactors, chemical processing plants, and solid and liquid waste storage facilities. The Burial Ground Complex in the central part of SRS received low- and intermediate-level radioactive and mixed waste from 1952-1995. The source term of the waste is somewhat uncertain, and has leaked to groundwater creating plumes of hazardous chemicals, metals, and radionuclides. Closure of the Complex will include removal or stabilization of highly contaminated zones, an engineered and layered cover, possibly consisting of synthetic material, and long term monitoring and surveillance.

    A persistent DNAPL plume of 140 hectares is associated with a manufacturing area in the northern portion of the site. From the 1950s to the 1980s, wastewater from fuel and target manufacturing seeped into the ground via an overflow basin, releasing solvents and heavy metals to the environment. A pump and treat system at the down gradient end of the plume controls spreading; 400 monitoring wells are used to collect data for surveillance and modeling. Site engineers and scientists continue to look for new technologies and methods to better characterize, describe, and remediate the plume and its source(s). Investigators are referred to the SRS website at: http://www.srs.gov/general/scitech/scitech.htm to review science and technology needs, as well as related information.

    OFFICE OF SCIENCE GUIDE FOR PREPARATION OF SCIENTIFIC/TECHNICAL PROPOSALS TO BE SUBMITTED BY NATIONAL LABORATORIES

    Proposals from National Laboratories submitted to the Office of Science (SC) as a result of this program announcement will follow the Department of Energy Field Work Proposal process with additional information requested to allow for scientific/technical merit review. The following guidelines for content and format are intended to facilitate an understanding of the requirements necessary for SC to conduct a merit review of a proposal. Please follow the guidelines carefully, as deviations could be cause for declination of a proposal without merit review.

    1. Evaluation Criteria

    Proposals will be subjected to formal merit review (peer review) and will be evaluated against the following criteria, which are listed in descending order of importance:

    Scientific and/or technical merit of the project
    Appropriateness of the proposed method or approach
    Competency of the personnel and adequacy of the proposed resources
    Reasonableness and appropriateness of the proposed budget
    The evaluation will include program policy factors such as the relevance of the proposed research to the terms of the announcement, the uniqueness of the proposer's capabilities, and demonstrated usefulness of the research for proposals in other DOE Program Offices as evidenced by a history of programmatic support directly related to the proposed work.

    4. Detailed Instructions for the Budget
    (DOE Form 4620.1 "Budget Page" may be used)

    4.1 Salaries and Wages

    List the names of the principal investigator and other key personnel and the estimated number of person-months for which DOE funding is requested. Proposers should list the number of postdoctoral associates and other professional positions included in the proposal and indicate the number of full-time-equivalent (FTE) person-months and rate of pay (hourly, monthly or annually). For graduate and undergraduate students and all other personnel categories such as secretarial, clerical, technical, etc., show the total number of people needed in each job title and total salaries needed. Salaries requested must be consistent with the institution's regular practices. The budget explanation should define concisely the role of each position in the overall project.

    4.2 Equipment

    DOE defines equipment as "an item of tangible personal property that has a useful life of more than two years and an acquisition cost of $25,000 or more." Special purpose equipment means equipment, which is used only for research, scientific, or other technical activities. Items of needed equipment should be individually listed by description and estimated cost, including tax, and adequately justified. Allowable items ordinarily will be limited to scientific equipment that is not already available for the conduct of the work. General-purpose office equipment normally will not be considered eligible for support.

    4.3 Domestic Travel

    The type and extent of travel and its relation to the research should be specified. Funds may be requested for attendance at meetings and conferences, other travel associated with the work and subsistence. In order to qualify for support, attendance at meetings or conferences must enhance the investigator's capability to perform the research, plan extensions of it, or disseminate its results. Consultant's travel costs also may be requested.

    4.4 Foreign Travel

    Foreign travel is any travel outside Canada and the United States and its territories and possessions. Foreign travel may be approved only if it is directly related to project objectives.

    4.5 Other Direct Costs

    The budget should itemize other anticipated direct costs not included under the headings above, including materials and supplies, publication costs, computer services, and consultant services (which are discussed below). Other examples are: aircraft rental, space rental at research establishments away from the institution, minor building alterations, service charges, and fabrication of equipment or systems not available off-the-shelf. Reference books and periodicals may be charged to the project only if they are specifically related to the research.

    a. Materials and Supplies

    The budget should indicate in general terms the type of required expendable materials and supplies with their estimated costs. The breakdown should be more detailed when the cost is substantial.

    b. Publication Costs/Page Charges

    The budget may request funds for the costs of preparing and publishing the results of research, including costs of reports, reprints page charges, or other journal costs (except costs for prior or early publication), and necessary illustrations.

    c. Consultant Services

    Anticipated consultant services should be justified and information furnished on each individual's expertise, primary organizational affiliation, daily compensation rate and number of days expected service. Consultant's travel costs should be listed separately under travel in the budget.

    d. Computer Services

    The cost of computer services, including computer-based retrieval of scientific and technical information, may be requested. A justification based on the established computer service rates should be included.

    e. Subcontracts

    Subcontracts should be listed so that they can be properly evaluated. There should be an anticipated cost and an explanation of that cost for each subcontract. The total amount of each subcontract should also appear as a budget item.
