SUPPLEMENTARY INFORMATION:

Background

For more than 50 years, the U.S. created a vast network of more than 113 facilities for research, development, testing and production of nuclear weapons. As a result of these activities, subsurface contamination has been identified at over 7,000 discrete sites across the U.S. Department of Energy complex. With the end of the Cold War threat, the DOE has shifted its emphasis to remediation, decommissioning, and decontamination of contaminated groundwater, sediments, and structures at its sites. DOE is currently responsible for remediating 1.7 trillion gallons of contaminated groundwater and 40 million cubic meters of contaminated soil. It is estimated that more than 60% of DOE facilities have groundwater contaminated with metals or radionuclides. More than 50% of all DOE facilities have soils or sediments contaminated with radionuclides and metals. While virtually all of the contaminants found at industrial sites nationwide can also be found at DOE sites, many of the metals and most of the radionuclides are unique to DOE sites. The NABIR program aims: 1) to provide the fundamental knowledge that may lead to new remediation technologies or strategies for radionuclides and metals; and 2) to advance the understanding of the key microbiological and geochemical processes that control the effectiveness of in situ immobilization as a means of long term stewardship, and how these processes impact contaminant transport.

While bioremediation of organic contaminants involves their biotransformation to benign products such as carbon dioxide, bioremediation of radionuclides and metals involves their removal from the aqueous phase to reduce risk to humans and the environment. Microorganisms can directly affect the solubility of radionuclides and metals by changing their oxidation state to a reduced form that leads to in situ immobilization. Or, microorganisms can indirectly immobilize radionuclides and metals through the reduction of inorganic ions that can, in turn, chemically reduce contaminants to less mobile forms. The long term stability of these reduced contaminants is as yet unknown.

NABIR Program

The goal of the NABIR program is to provide the fundamental science that will serve as the basis for development of cost-effective bioremediation and long-term stewardship of radionuclides and metals in the subsurface at DOE sites. An important aspect to the NABIR program is to assess factors controlling the long-term stability of the immobilized contaminants and to devise approaches (biological/chemical) to maintain their immobilization through the stewardship phase. Naturally-occurring subsurface microbes may be involved in intrinsic bioremediation of radionuclides and metals by reduction and immobilization, either directly or indirectly. However, these natural processes (known as natural attenuation) typically occur at fairly slow rates, and there may be a need to use biostimulation to enhance the rates. The primary focus of the NABIR program is on biostimulation strategies, due to the ubiquity of metal-reducers in nature. Immobilized radionuclides and metals are not removed from the subsurface as may occur with excavation, pump and treat, or biodegradation of organic contaminants. Thus, understanding the potential for remobilization of contaminants is of special interest.

The focus of the NABIR program is on radionuclides and metals that: 1) pose the greatest potential risk to humans and the environment at DOE sites; and 2) are amenable to immobilization by means of bioremediation. Thus, research is focused on the radionuclides uranium, technetium and plutonium and the metals chromium and mercury. Radioactive contaminants such as tritium and cobalt are not a focus because of their relatively short half lives, and strontium and cesium are not addressed because they are not readily amenable to biotransformation. Research is focused on subsurface sediments below the zone of root influence and includes both the vadose (unsaturated) zone and the saturated zone (both groundwater and sediments). Research on phytoremediation will not be supported by this solicitation.

NABIR is oriented toward areas that have low levels of widespread contamination; it is too costly to clean up those situations with existing technologies. Uranium, technetium, and chromium can be especially mobile in the subsurface under certain conditions; they are risk- driving contaminants at some DOE sites. The effects of co-contaminants such as nitrate, complexing agents (such as EDTA) and chlorinated solvents (such as trichloroethylene and carbon tetrachloride) on the behavior of radionuclides and metals in the subsurface is also of interest to the NABIR program. The NABIR Program supports hypothesis-driven, basic research that is more fundamental in nature than demonstration projects.

The NABIR program consists of four interrelated Science Elements (Biogeochemistry, Biotransformation, Community Dynamics and Microbial Ecology, and Biomolecular Science and Engineering). Innovative method development for the Science Elements is supported under the Assessment Element. The program also includes an element addressing ethical, legal and societal issues called Bioremediation and its Societal Implications and Concerns (BASIC). The NABIR program strongly encourages researchers to integrate laboratory and field research at DOE or DOE-relevant sites. More information on the NABIR program may be found at: http://www.lbl.gov/NABIR/.

The NABIR Field Research Center (FRC) and Other Field Research Sites

To encourage hypothesis-based field research and process-level understanding, the NABIR program established the Field Research Center (FRC) for long-term field studies. The FRC provides a site for investigators to conduct field-scale research and to obtain DOE-relevant subsurface samples for laboratory-based studies of bioremediation, and it is located on the U.S. Department of Energy Oak Ridge Reservation in Oak Ridge, Tennessee. The FRC is operated by the Environmental Sciences Division of the Oak Ridge National Laboratory, and it includes a contaminated and a background (uncontaminated control) area for in situ studies. Both areas are located in Bear Creek Valley (BCV) within the Y-12 Plant area.

The contaminated research site at the FRC is a 98-hectare plot containing uranium, nitrate, technetium-99, strontium, and cadmium in groundwater, soils, and sediments. To a lesser extent, metals such as mercury, copper, zinc, and lead, and organics such as acetone, methylene chloride, tetrachloroethylene, and toluene are also present. The contaminated area includes the groundwater plume that originated from the S-3 Waste Disposal Ponds.

The background area is approximately 163 hectares and is located in West Bear Creek Valley, about 2 km from the contaminated area. The area lies directly along the geologic strike of the contaminated area and is, therefore, underlain by nearly identical geology, mineralogy, and structure. No known contaminants have been disposed at this location throughout the history of DOE operations. The majority of the area is heavily wooded, with the exception of the Bear Creek floodplain.

Both the background and contaminated areas are well-characterized and well-instrumented, and should be available for five to ten years. The water table resides between 0 and 3 meters below the surface and is readily accessible through multilevel groundwater monitoring wells.

The FRC is responsible for general site characterization activities and provides a rich database for use by NABIR researchers. The FRC is responsible for data management, systems integration, and fundamental hydrological and geochemical modeling of the contaminated and background sites. The FRC makes these data and models accessible to all researchers. See: http://www.esd.ornl.gov/nabirfrc for more detailed information on the NABIR FRC.

While the FRC provides a major focus for the NABIR program, it is recognized that other sites that represent the different hydrogeological regimes found at DOE sites will also be valuable to researchers. A large fraction of the national inventory of DOE wastes resides in unconsolidated, porous media in relatively thick, vadose zones and in groundwaters low in soluble organic carbon. For this reason, NABIR investigators are encouraged to take advantage of opportunities to collect and analyze samples from arid western environments that typify the Hanford Reservation and Uranium Mill Tailings Remedial Action (UMTRA) sites. For further information on NABIR Field Research, please contact Mr. Paul Bayer (paul.bayer@ science.doe.gov), the NABIR Field Activities Manager.

Resources at DOE User Facilities

Researchers are encouraged to propose making use of the capabilities provided by DOE’s National Scientific User Facilities. The instrumentation and experimental facilities at these user facilities are available free of charge to users who agree to publish their findings in the peer reviewed literature. Researchers may be interested in one or more of the following DOE user facilities:

Researchers may be interested in the capabilities offered at the Environmental Molecular Sciences Laboratory (EMSL), which is located at the Pacific Northwest National Laboratory in Richland, WA. EMSL provides users with unique and leading edge instrumentation for molecular-level studies, including a wide variety of capabilities in spectroscopy and microscopy, particle characterization and imaging, and meter-scale reactive transport. These experimental capabilities are located within EMSL’s high field magnetic resonance, high performance mass spectrometry, interfacial and nanoscale science and optical imaging and spectroscopy facilities. In addition, the high-performance molecular science computing facility within the EMSL includes an 11.8 TeraFlop supercomputer for use in reactive transport and flow modeling. See http://www.emsl.pnl.gov for further information.

Researchers may also be interested in the molecular-level capabilities for studying the speciation, properties or behavior of contaminants that are available through DOE’s synchrotron radiation facilities. Information concerning the types of analytical techniques available at specific synchrotron facilities is available through EnviroSync, a national organization that represents molecular environmental science at the synchrotrons. See http://www.cems.stonybrook.edu/envirosync/ for further information.

Current Request for Proposals

Research projects should address the scientific aims of 1) individual NABIR elements including Biogeochemistry, Biotransformation, Community Dynamics and Assessment; 2) Integrative, interdisciplinary studies that involve research from more than one element; or 3) Field research projects to be performed at the NABIR FRC in Oak Ridge, Tennessee. The focus is on field research, or laboratory studies that can be scaled to the field, to provide supporting information for current or future field research. The NABIR FRC provides an opportunity for researchers to work at a DOE site in collaboration with scientists from different research elements. Studies at the NABIR FRC show that microbial reduction of radionuclides and metals is affected by the presence of nitrate and low pH. Thus, research into microbial mechanisms involved in the reduction of radionuclides and metals in this type of subsurface environment is of special interest.

Biogeochemistry: The goal of this element is to understand the fundamental biogeochemical reactions that would lead to long-term immobilization of metal and radionuclide contaminants in the subsurface, and the potential for remobilization. The focus is on reactions that govern the concentration, chemical speciation, and distribution of metals and radionuclides between the aqueous and solid phases. Biogeochemical reactions in subsurface environments are influenced by a wide variety of factors, including the availability of electron donors and acceptors, the nature of the microbial community, the chemical species or form of contaminant, the hydrogeology of the site, and the nature of the environmental matrix. Often several competing redox reactions make the prediction of the substrates, products, and kinetics difficult. The biogeochemical reactions are further complicated by the sorption of contaminants and reaction products to mineral surfaces, and the presence of natural organic matter and co-contaminants. The research challenge is to identify and prioritize the key biogeochemical reactions that are needed to predict the rate and extent of reactions that result in the immobilization of radionuclides and metals. New and creative scientific approaches are sought that address the following fundamental research questions:

  • To increase immobilization of radionuclides and metals, what are the principal biogeochemical reactions that govern the concentration, chemical speciation, and distribution of metals and radionuclides between the aqueous and solid phases (with an emphasis on natural geological matrices)? What are the thermodynamic and kinetic controls on these reactions? How do factors such as co-contaminants, sorption processes, and terminal electron acceptors (e.g., nitrate, iron, sulfate), influence these reactions?
  • Under what conditions would the contaminants remobilize, and what alterations to the environment would increase the long term stability of metals and radionuclides in the subsurface?
  • What influence do hydrological processes such as reactive transport, advective/dispersive transport and colloidal transport have on the biological availability, biotransformation, and movement of radionuclides and metals?

Biotransformation: The goal of this element is to understand the mechanisms of microbially mediated transformation of metals and radionuclides in subsurface environments leading to in situ immobilization and long term stability. Physiological studies of the biotransformation of metals and radionuclides by subsurface microorganisms will provide the knowledge base needed to understand intrinsic bioremediation and to stimulate biotransformation in situ .

DOE subsurface sites encompass a range of redox environments where contaminants such as uranium are present. One challenge is to understand the impact of these environments on microbial physiological processes involved in the biotransformation of radionuclides and metals to an immobilized form. Knowledge of the metabolic pathways for biotransformation of these contaminants by naturally occurring microbial communities in vadose zones, saturated zones and the waste plume is needed. A second challenge is to accelerate the rates of these physiological processes in situ , in complex subsurface environments. Biotransformation of metals and radionuclides in the subsurface is poorly understood, and predictive models based on laboratory studies have not always accurately simulated the observed fate of metals and radionuclides in the field. It is important to understand the kinetics of desirable metal and radionuclide biotransformations and the physicochemical factors affecting those kinetics in the field. Research is needed to address questions such as:

  • What are the primary metabolic pathways for biotransformation of radionuclides and/or metals by subsurface microorganisms at DOE sites, such as the FRC? Physiological processes studied at the laboratory scale will need to demonstrate how results will be scaled to the field.
  • How can metal reduction be harnessed or accelerated to immobilize radionuclides and/or metals in the subsurface? Can in situ production of organic acids, chelators, or extracellular polymers affect contaminant mobility?
  • What environmental controls affect microbial physiological processes involved in radionuclide and metal biotransformations leading to immobilization in vadose and saturated zones? What factors inhibit these biotransformations in situ ?
  • How can we quantify in situ biotransformation kinetics so that these parameters can be applied to numerical models of field scale bioremediation?

Community Dynamics and Microbial Ecology: The goal of this element is to determine the potential for natural microbial communities to immobilize radionuclides and metals. In particular, research focuses on: 1) understanding the structure and function of microbial communities in the subsurface at DOE sites contaminated with metals and radionuclides; and 2) identifying and optimizing the in situ growth of microorganisms that transform radionuclides and metals. This research will enhance our ability to predict the effectiveness of intrinsic bioremediation and to optimize microbial community composition for in situ immobilization of these contaminants. Diverse microbial communities can be found in subsurface environments. These communities represent an untapped catalytic potential for biotransformation of radionuclides and metals. Most of these microbes, however, are as yet uncultured using current methods. One challenge is to determine if sufficient genotypic and/or phenotypic potential exists to support natural and/or accelerated (biostimulated) bioremediation. Knowledge of microbial community structure and function may ultimately provide the ability to control or stimulate subsurface communities capable of biotransformation of radionuclides and metals. A second challenge is to optimize the community structure and activity for immobilization and metals, and to determine the long term stability of bioremediative communities. Research is needed to address questions such as:

  • Is there sufficient biological activity and diversity in subsurface environments to support natural and/or accelerated bioremediation of metals and radionuclides?
  • What are the effects of metal and radionuclide contamination on microbial community structure and function, particularly on populations that transform radionuclides and metals? What are the effects of key physical, chemical and hydrological factors on community structure and function, as it relates to immobilization of metals and radionuclides?
  • What is the role of consortial interactions in subsurface environments contaminated with radionuclides and metals? Such interactions might include competition for electron donors and acceptors, or consortial interactions in the biotransformation of metals and radionuclides.
  • What is the potential importance of gene transfer in natural microbial communities at subsurface sites contaminated with radionuclides or metals?

Those studies that link structure to function of microbial communities that immobilize metals and/or radionuclides at DOE sites are especially encouraged.

Assessment: Assessment is a cross-cutting element with a goal to develop innovative methods to assess processes and endpoints in support of the NABIR Science Elements. Thus, assessment projects are being sought that support the Science Elements of Biogeochemistry, Biotransformation, and Community Dynamics/Microbial Ecology. Methods may range from molecular to field scale, but they should improve the understanding of in situ bioremediation processes in subsurface environments contaminated with radionuclides and metals. Priority will be given to research proposals that could lead to fieldable, cost-effective, real time assessment techniques and/or instrumentation. NABIR will not fund projects that examine endpoints relating to human health risks. Research should address the development of innovative and effective methods for assessing or quantifying:

  • Biogeochemical or biotransformation processes and rates, and microbial community structure and function relative to bioremediation of metals and radionuclides.
  • Bioremediation end points, in particular, the concentration, speciation and stability of radionuclide and metal contaminants.

Techniques must enable NABIR science and address specific science needs of the program. The researcher should explain the potential impact and contribution to the NABIR program, as well as the relevance and potential usefulness of the innovation.

Integrative Studies: This solicitation especially encourages those studies that integrate research from more than one NABIR research element through laboratory and/or field research. This interdisciplinary research should focus on achieving the primary goals of the NABIR program through collaborative studies in which the experimental design integrates two or more NABIR elements. Interdisciplinary teams should include participation from two or more research areas such as microbiology, geochemistry, hydrology, environmental engineering, numerical modeling or other disciplines. Partnering with specific field experiments may provide information for hypothesis testing. Such integrative studies might include, for example:

  • Employing numerical modeling to integrate information from more than one element, such as Biogeochemistry, Biotransformation, and Community Dynamics and Microbial Ecology, to better predict in situ immobilization of metals and radionuclides
  • Studies of the effects of key physical, geochemical and hydrological parameters on the structure and function of subsurface microbial communities engaged in metal/radionuclide biotransformation and immobilization
  • Integration of new methods in the Assessment element with actual application to studies of biotransformation or biogeochemistry of radionuclide/metal reduction and precipitation
  • Linking chemical speciation of radionuclides and metals in subsurface environments to the bioavailability of those contaminants to microorganisms
  • Studies on the changes of subsurface microbial community structure and function, and the effect on net rates of biotransformation during biostimulation experiments

Field Scale Bioremediation Experiments

Although bioremediation of radionuclides and metals has been studied in the laboratory, and bioremediation technologies have been demonstrated in the field, there are few examples of carefully controlled, hypothesis-driven, in situ bioremediation research at the field-scale. The FRC provides opportunities for such field-scale experiments.

The S-3 Ponds were the primary source of contamination detected in the contaminated zone of the FRC. The S-3 Ponds consisted of four unlined ponds constructed in 1951 on the west end of the Y-12 Plant at Oak Ridge. Liquid wastes, composed primarily of nitric acid plating wastes containing nitrate and various radionuclides and metals (e.g., uranium and technetium), were disposed in the ponds until 1983. Waste disposal activities at the Y-12 Plant created a mixed waste plume of contamination in the underlying unconsolidated residuum (primarily saprolite and fill) and shale bedrock. The ponds were neutralized and denitrified in 1984 and capped in 1988, and the area is now a parking lot.

Three areas in the contaminated zone are currently identified as the primary targets for in situ studies. Areas 1 and 3 are located adjacent and directly south and west, respectively, of the S-3 Ponds parking lot and Area 2 is located several hundred feet to the southwest of the parking lot. Researchers may choose to propose research for Area 1 (a high nitrate, low pH site), Area 2 (a low nitrate, circumneutral site) or Area 3 (a very high contaminant concentration, very low pH site). More detailed information on Areas 1, 2 and 3 can be found on the NABIR FRC web site (http://public.ornl.gov/nabirfrc/area123.cfm).

The initial focus of in situ research conducted at the FRC has been on biostimulation experiments to understand or promote the immobilization of uranium and technetium by microbial processes. Understanding natural and stimulated uranium biotransformation in the presence of high nitrate and low pH in unconsolidated residuum and fractured rock is one of the biggest challenges at the FRC at Oak Ridge, and at other DOE sites. The NABIR program is currently funding the following three in situ projects within the contaminated area of the FRC: 1) a stimulated biocurtain for uranium biotransformation combined with denitification, 2) push- pull tests to determine the kinetics of electron-acceptor and electron-donor use for microbially- mediated uranium and technetium reduction and reoxidation, and 3) stimulation of microbial uranium reduction in hydrologically-accessible fractured zones to precipitate uranium oxide and isolate the uranium in low-permeability porous regions. Researchers should attempt to complement existing projects; additional information can be found at http://public.ornl.gov/nabirfrc/awards.cfm.

For this solicitation, the NABIR program is seeking proposals that focus on in situ studies that are aligned with the short- and mid-term scientific tasks outlined in the recently completed strategic plan for the FRC ( http://public.ornl.gov/nabirfrc/FRCStrategicPlan070103.pdf). Proposals should therefore focus on field conditions or processes that affect microbial oxidation/reduction and contaminant transport at the meter or tens of meters scale. The results of in situ research should lead to improved parameters for modeling the fate and transport of uranium, technetium or other contaminants. For example, research could be undertaken on microbial metal reduction in the presence of preferential contaminant flow pathways in the saprolite or in reworked fill, during storm events, in the vadose zone, at increasing distance from the source, or at the seasonally variable capillary fringe. Research findings are expected to be useful for incorporation into a site-wide FRC model for reactive transport and groundwater flow.

Researchers must propose a testable hypothesis that is based on microbially-mediated mechanisms of immobilization for in situ field research, and they should describe a detailed technical approach that should include 1) establishing a defined (surface area and depth) experimental and control plot within the proposed contaminated field site, and 2) manipulating the experimental plot by amendments of nutrients or other chemicals that might stimulate microbial communities to immobilize uranium or technetium. The technical approach must be described in phases such that completion of each phase could result in publishable results. A statistically robust sampling regimen to determine the efficacy of the manipulation should also be described. Moreover, the researcher must explain the technical feasibility of performing the proposed field research. Technology demonstration projects will not be funded by this solicitation.

The researchers must propose research to be performed as an interdisciplinary team including, at a minimum, expertise in microbiology, geochemistry, and hydrology. The Principal Investigator for the team must have prior experience in relevant field research, and the activities of each team member must be clearly defined. Multi-institutional partnerships are strongly encouraged; for example, researchers may draw expertise from National Laboratories, academia, and other institutions engaged in basic research. The successful team must be willing to partner with other funded NABIR investigators who may wish to obtain samples in conjunction with the proposed field studies.

Although compliance with National Environmental Policy Act (NEPA) is the responsibility of DOE, successful researchers who propose to conduct field research are expected to provide information necessary for the DOE to complete the NEPA review and documentation. Successful researchers will also be expected to brief and to obtain approval of their written work plan from the Field Research Review Panel (FRRP) prior to beginning their field work. For this solicitation, researchers should describe how they would communicate their proposed experimental design and their results to stakeholders, regulators, and community groups. Researchers may wish to review the FRC Communication Plan, which can be found on the FRC web site. All researchers should discuss other relevant societal issues, where appropriate, which may include intellectual property protection, and communication with and outreach to affected communities (including members of affected minority communities where appropriate) to explain the proposed research. For further information on NABIR Field Research, please contact Mr. Paul Bayer (Paul.Bayer@ science.doe.gov), the NABIR Field Activities Manager.

Subcontract or Consortium Arrangements: If any portion of the project described under "Research Design and Methods" is to be done in collaboration with another institution, provide information on the institution and why it is to do the specific component of the project. Further information on any such arrangements is to be given in the sections "Budget and Budget Explanation", "Biographical Sketches", and "Description of Facilities and Resources".

3.6 Literature Cited

List all references cited in the narrative. Limit citations to current literature relevant to the proposed research. Information about each reference should be sufficient for it to be located by a reviewer of the proposal.

3.7 Budget and Budget Explanation

A detailed budget is required for the entire project period, which normally will be three years, and for each fiscal year. It is preferred that DOE's budget page, Form 4620.1 be used for providing budget information*. Modifications of categories are permissible to comply with institutional practices, for example with regard to overhead costs.

A written justification of each budget item is to follow the budget pages. For personnel this should take the form of a one-sentence statement of the role of the person in the project. Provide a detailed justification of the need for each item of permanent equipment. Explain each of the other direct costs in sufficient detail for reviewers to be able to judge the appropriateness of the amount requested.

Further instructions regarding the budget are given in section 4 of this guide.

* Form 4620.1 is available at web site: http://www.sc.doe.gov/production/grants/Forms-E.html

3.8 Other Support of Investigators

Other support is defined as all financial resources, whether Federal, non-Federal, commercial or institutional, available in direct support of an individual's research endeavors. Information on active and pending other support is required for all senior personnel, including investigators at collaborating institutions to be funded by a subcontract. For each item of other support, give the organization or agency, inclusive dates of the project or proposed project, annual funding, and level of effort devoted to the project.

3.9 Biographical Sketches

This information is required for senior personnel at the laboratory submitting the proposal and at all subcontracting institutions. The biographical sketch is limited to a maximum of two pages for each investigator.

3.10 Description of Facilities and Resources

Describe briefly the facilities to be used for the conduct of the proposed research. Indicate the performance sites and describe pertinent capabilities, including support facilities (such as machine shops) that will be used during the project. List the most important equipment items already available for the project and their pertinent capabilities. Include this information for each subcontracting institution, if any.

3.11 Appendix

Include collated sets of all appendix materials with each copy of the proposal. Do not use the appendix to circumvent the page limitations of the proposal. Information should be included that may not be easily accessible to a reviewer.

Reviewers are not required to consider information in the Appendix, only that in the body of the proposal. Reviewers may not have time to read extensive appendix materials with the same care as they will read the proposal proper.

The appendix may contain the following items: up to five publications, manuscripts (accepted for publication), abstracts, patents, or other printed materials directly relevant to this project, but not generally available to the scientific community; and letters from investigators at other institutions stating their agreement to participate in the project (do not include letters of endorsement of the project).

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.

4.6 Indirect Costs

Explain the basis for each overhead and indirect cost. Include the current rates.
