This memorandum summarizes steps taken regarding formation of a Science Advisory
Board ad hoc committee to conduct an evaluative study entitled Reactive Nitrogen: An
Integrated Approach and documents the determination process for appointing members to the
Integrated Nitrogen Committee.

Formation of the Integrated Nitrogen Committee

The SAB Environmental Engineering Committee identified integrated nitrogen research
and control strategies as an important environmental issue. Subsequent discussions with the
Agency and the chartered Board indicated that this topic warranted the SAB's attention. The
SAB Staff Office announced its intention to form an Integrated Nitrogen Committee, and sought
public nominations for this committee in a Federal Register notice dated March 14, 2005 (70
FR 48: 2476-12477). The notice (Attachment 1) requested public nominations of technical
experts with expertise in nitrogen biogeochemistry, effects, risk reduction, and control
technologies. The committee will evaluate EPA environmental research and programs on
reactive nitrogen, recommend improvements for research, and identify opportunities for
integrated approaches to nitrogen management.

-------
Fifty-one experts were identified for the Integrated Nitrogen Panel. The names and
biosketches were posted on the SAB website with a request for public comment on August 21,
2006. (Attachment 2 is the Invitation to Comment.) The SAB Staff Office received 17 sets of
public comments. (Attachment 3 lists those who provided comments.)

Conflict of Interest Considerations

18 U.S.C. 208 provision states that:

"An employee is prohibited from participating personally and substantially in an official capacity
in any particular matter in which he, to his knowledge, or any person whose interests are imputed
to him under this statue has a financial interest, if the particular matter will have a direct and
predictable effect on that interest [emphasis added]."

For a conflict of interest to be present, all elements in the above provision must be
present. If an element is missing, the issue does not involve a formal conflict of interest.
However, the general provisions in the "appearance of a lack of impartiality guidelines" may still
apply and need to be considered.

Personal and Substantial Participation:

Participating "personally," means direct participation. Participating "substantially" refers
to involvement that is of significance to the matter [5C.F.R. 2640.103(a)(2)], For this review,
committee members will be participating personally in the matter through attendance at
meetings, teleconferences and other means.

Direct and Predictable Effect:

A direct effect on a participant's financial interest exists if, "... a close causal link exists
between any decision or action to be taken in the matter and any expected effect of the matter on the
financial interest... A particular matter does not have a direct effect...if the chain of causation is attenuated
or is contingent upon the occurrence of events that are speculative or that are independent of, and
unrelated to, the matter. A particular matter that has an effect on a financial interest only as a
consequence of its effects on the general economy is not considered to have a direct effect." [5 C.F.R.
2640.103(a)(i)]. A predictable effect exists if, "...there is an actual, as opposed to a speculative,
possibility that the matter will affect the financial interest." [5 C.F.R. 2640.103(a) (ii)].

Particular Matter:

A "particular matter" refers to matters that "...will involve deliberation, decision, or
action that is focused upon the interests of specific people, or a discrete and identifiable class of
people." It does not refer to "...consideration or adoption of broad policy options directed to the
interests of a large and diverse group of people." [5 C.F.R. 2640.103 (a)(1)].

The subject matter to be covered by this committee affects the interests of a large and
diverse group of people. Therefore, the work of the committee is not considered to be a

-------
particular matter as defined under 5 C.F.R. 2640.103(a)(1). As a result, the possibility of a
conflict of interest is attenuated.

Appearance of a Lack of Impartiality Considerations:

The Code of Federal Regulations [5 C.F.R. 2635.502(a)] states that:

"Where an employee knows that a particular matter involving specific parties is likely to have a
direct and predictable effect on the financial interest of a member of his household, or knows that
a person with whom he has a covered relationship is or represents a party to such matter, and
where the person determines that the circumstances would cause a reasonable person with
knowledge of the relevant facts to question his impartiality in the matter, the employee should not
participate in the matter unless he has informed the agency designee of the appearance problem
and received authorization from the agency designee."

Further, 5 C.F.R. 2635.502(a)(2) states that:

"An employee who is concerned that circumstances other than those specifically described in this
section would raise a question regarding his impartiality should use the process described in this
section to determine whether he should or should not participate in a particular matter."

Each potential advisory committee member will be evaluated against the 5 C.F.R.
2635.502(a) general requirements for considering an appearance of a lack of impartiality.
Information used in this evaluation has come from information provided by potential advisory
committee members (including, but not limited to, EPA 3110-48 confidential financial disclosure
forms) and public comment.

To further evaluate any potential appearance of a lack of impartiality, the following five
questions were posed to all prospective advisory committee members

1)	Do you know of any reason that you might be unable to provide impartial advice on

the matter to come before the Committee or any reason that your impartiality in
the matter might be questioned?

2)	Have you had any previous involvement with U.S. EPA or other federal agency

research or operational programs concerning reactive nitrogen, including
collaboration, authorship or co-authorship of federal documents, or peer review
functions?

3)	Have you served on previous advisory panels or committees that have addressed the

topic under consideration?

4)	Have you made any public statements (written or oral) on the issue?

5)	Have you made any public statements that would indicate to an observer that you have

taken a position on the issue under consideration?

-------
Prospective committee members were asked to provide information that would allow the
SAB Staff Office to evaluate the possibility of a conflict of interest or a potential appearance of a
lack of impartiality. Information used in this evaluation includes the confidential financial
disclosure form (3110-48), the responses to the five questions above, and public comments.

The SAB Staff Office Director made the final decision about who serves on the Panel
based on all relevant information. For the EPA SAB Staff Office, a balanced committee or panel
is characterized by inclusion of candidates who possess the necessary domains of knowledge, the
relevant scientific perspectives (which, among other factors, can be influenced by work history
and affiliation), and the collective breadth of experience to adequately address the general
charge. Specific criteria to be used in evaluation an individual committee member include: (a)
scientific and/or technical expertise, knowledge, and experience; (b) availability and willingness
to serve; (c) absence of financial conflicts of interest; (d) absence of an appearance of a lack of
impartiality; and, for the Committee as a whole, (f) diversity of, and balance among, scientific
expertise, endpoints, and adequate representation from existing SAB Committees and Panels
addressing related issues.

ENVIRONMENTAL PROTECTION AGENCY [FRL-7884-1] Science Advisory Board Staff
Office; Request for Nominations, Ad Hoc Integrated Nitrogen Research Committee of the
Science Advisory Board AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

SUMMARY: The U.S. Environmental Protection Agency (EPA or Agency) Science Advisory
Board (SAB) Staff Office (hereinafter, the Staff Office") is announcing the formation of a new
Ad Hoc Integrated Nitrogen Research Committee of the Science Advisory Board (hereinafter,
the "Committee") and is hereby soliciting nominations for this Committee.

DATES: Nominations should be submitted by April 11, 2005, per the instructions below.

FOR FURTHER INFORMATION CONTACT: Any member of the public wishing further
information regarding this Request for Nominations may contact Ms. Kathleen White,
Designated Federal Officer (DFO), EPA Science Advisory Board Staff, at telephone/voice mail:
(202) 343-9878; or via e-mail at: white.kathleen@epa.gov. General information concerning the
SAB can be found on the EPA Web site at: http://www.epa.gov/sab.

SUPPLEMENTARY INFORMATION: Background Reactive nitrogen compounds (Nr)--that is,
all biologically active, photochemically reactive, and radiatively active nitrogen compounds in
the atmosphere and biosphere of the Earth can cause multiple effects in the atmosphere, in
terrestrial ecosystems, in freshwater and marine systems, and on human health. The result is a
wide variety of beneficial and detrimental changes in the health and welfare of people and
ecosystems. Information to date indicates reactive nitrogen is accumulating in the environment.

Anthropogenic activity leading to production of reactive nitrogen has been shown to
exceed that from natural systems. Circulation of reactive nitrogen in the atmosphere,
hydrosphere and biosphere of the Earth has a wide variety of consequences that are magnified
with time as reactive nitrogen moves along its biogeochemical pathway. Furthermore, research
indicates the influence of reactive nitrogen in the environment should be considered from a
systems perspective and integrated across environmental media. For example, reactive nitrogen
that produces urban air pollution can also contribute to water pollution and the extensive use of
nitrogen- containing materials in a watershed has a strong impact on the health of the associated
coastal zone. Accordingly, there is a need to assess the extent of linkage among the effects that
nitrogen causes in the environment, and to explore the implications of these linkages for nitrogen
research and risk management.

The EPA Science Advisory Board (SAB) was established by 42 U.S.C. 4365 to provide
independent scientific and technical advice, consultation, and recommendations to the EPA
Administrator on the technical bases for EPA policies and regulations. It is the initial assessment
of the SAB that EPA's research programs on Nr could be better integrated. The SAB is
conducting a study to assess the degree of integration among the current EPA programs, to make
recommendations for a more integrated research program on Nr, and to identify opportunities for
a more integrated approach to nitrogen management. To carry out the Integrated Nitrogen
Research Project, the SAB is forming an Ad Hoc Committee, known as the Integrated Nitrogen
Research Committee.

-------
The Staff Office is soliciting nominations for members of the new Committee. The
Committee will provide advice through the chartered SAB. The Committee will comply with the
provisions of the Federal Advisory Committee Act (FACA) and all appropriate SAB Staff Office
procedural policies. The Committee will address the following questions: 1. What are the
nitrogen problems? 2. What are the linkages among/between the different nitrogen problems? 3.
What EPA environmental programs and policies could provide the greatest control of nitrogen?
What are the benefits of integrated nitrogen management? 4. What are the research needs to
better understand the nitrogen problems and to strengthen the integrated risk management of
nitrogen?

To achieve these overall goals, the SAB plans to conduct a number of workshops and
issue reports for this study. Nomination of Candidates for SAB Committee The SAB Staff Office
is soliciting public nominations of nationally and internationally recognized scientists with
expertise in one or more of the following areas: Biogeochemistry and Effects (1) The sources of
Nr released into the environment from human activities and natural sources, including:

Intentional cultivation of crops which promote conversion of nitrogen gas to organic nitrogen;
combustion of fossil fuels; and the Haber-Bosch process. (2) The behavior and effects of Nr in
the atmosphere, including tropospheric ozone, particulate matter and visibility, and greenhouse
gases and stratospheric ozone. (3) The behavior and effects of Nr on humans and ecosystems in
the terrestrial environment, including grassland/forest and agroecosystem. (4) The behavior and
effects of nitrogen in the aquatic environment, including wetlands, groundwater, surface waters,
estuarine, coastal and marine environments. Risk Reduction (5) Risk Reduction Approaches
including implementation of regulatory and voluntary approaches to risk reduction. Control (6)
Specific control technologies or practices, including combustion controls for nitrogen oxides,
ozone precursors, and particulate matter/visibility and practices for controlling ammonia in
agriculture.

Process and Deadline for Submitting Nominations: Any interested person or organization
may nominate qualified experts from academia, industry, non-governmental organizations or
State, local and tribal governments in the areas of expertise described above to serve on the
Committee. Nominations should be submitted in electronic format through the Form for
Nominating Individuals to Panels of the EPA Science Advisory Board provided on the SAB Web
site at: http://www.epa. gov/sab. The form can be accessed through a link on the blue

and (vi) Sources of recent (i.e., within the preceding two years) grant and/or other contract
support, from government, industry, academia, etc., including the topic area of the funded
activity. Please note that even if there is no responsive information (e.g., no recent grant or
contract funding), this must be indicated on the biosketch (by "N/A" or '' None"). Incomplete
biosketches will result in nomination packages not being accepted. The EPA SAB Staff Office
will acknowledge receipt of the nomination.

-------
After considering the nominees (termed the Widecast"), the SAB Staff Office will
identify a subset (known as the "Short List") for more detailed consideration. Criteria used by
the Staff Office in developing this Short List are given at the end of the following paragraph. The
Short List will be posted on the SAB Web site at: http://www.epa.gov/sab. and will include the
nominees' names and their biosketches. Public comments will be accepted for 21 calendar days
on the Short List. During this comment period, the public may provide information, analysis or
other documentation on nominees that the Staff Office should consider in evaluating candidates
for the Committee.

For the EPA SAB Staff Office, a balanced Committee is characterized by inclusion of
candidates who possess the necessary domains of knowledge, the relevant scientific perspectives
(which, among other factors, can be influenced by work history and affiliation), and the
collective breadth of experience to adequately address the charge. Public responses to the Short
List candidates will be considered in the selection of the Committee, along with information
provided by candidates and information independently-gathered by the SAB Staff Office on the
background of each candidate (e.g., financial disclosure information and computer searches to
evaluate a nominee's prior involvement with the topic under review). Specific criteria to be used
in evaluating an individual Committee member include: (a) Scientific and/or technical expertise,
knowledge, and experience (primary factors); (b) availability and willingness to serve; (c)
absence of financial conflicts of interest; (d) scientific credibility and impartiality; and (e) skills
working in advisory committees, subcommittees and review panels.

Short List candidates must submit the "Confidential Financial Disclosure Form for
Special Government Employees Serving on Federal Advisory Committees at the U.S.
Environmental Protection Agency" (EPA Form 3110-48). This confidential form allows
Government officials to determine whether there is a statutory conflict between that person's
public responsibilities (which includes membership on an EPA Federal advisory committee) and
private interests and activities, or the appearance of a lack of impartiality, as defined by Federal
regulation. The form may be viewed and downloaded from the following URL address:

Dr. Patrick Brezonik is program director for environmental engineering at the National
Science Foundation. His research interests are focused on the impacts of human
activity on water quality and the biogeochemical cycles of important elements (nitrogen,
phosphorus, trace metals) in large natural systems-watersheds and lakes. Field
studies, including experimental manipulations in large systems, and modeling
approaches are emphasized. His current research projects are in four main areas: (1)
mercury biogeochemistry; (2) applications of satellite imagery to evaluate lake quality;
(3) coupled biogeochemical cycles of carbon, nitrogen and phosphorus in urban and
agricultural systems; and (4) small-scale nutrient cycling processes in soil-sediment-
water systems. His mercury research is concerned with chemical transformations of
mercury in wetland-lake ecosystems, with emphasis on photochemical processes and
interactions between mercury forms and natural organic matter (humic substances) in
these water bodies. My work with satellite imagery focuses on regional analyses and
long-term trend assessments of trophic state conditions in lakes by use of Landsat and
new satellite platforms. Our work on coupled biogeochemical cycles of the major
elements is highly interdisciplinary and involves comparative analyses at the regional
scale of nutrient budgets for urban, agricultural and natural regions in the Twin Cities
and Phoenix (Arizona) metropolitan areas. Quantifying the importance of denitrification
as a nitrogen sink in small agricultural streams is an example of a current project in the
fourth area. Some of this research is conducted through large multi-disciplinary
projects. For example, the experimental acidification of a whole lake in northern
Wisconsin was done in cooperation with limnologists, fisheries biologists, and
hydrologists from several institutions and agencies. Recent research has been
conducted in a variety of locations, including Lake Okeechobee, Florida, urban lakes in
the Twin Cities and pristine lakes in northern Michigan, Wisconsin, and Minnesota. He
holds the following degrees: B.S., 1963, Chemistry, Marquette University, M.S., 1965,
Water Chemistry, University of Wisconsin-Madison, and Ph.D., 1968, Water Chemistry,
University of Wisconsin-Madison

-------
He served as Assistant, Associate, and Full Professor, Department of Environmental
Engineering Sciences at the University of Florida from 1966-81 and Guest Professor at
EAWAG-Swiss Federal Institute of Technology (ETH) in Zurich, Switzerland, 1971-72
and summer, 1980

Dr. Richard G. Carlton manages the Electric Power Research Institute's Integrated
Facilities Water Management Program, and is responsible for strategic planning and
project management. Research emphases in the Program include novel approaches to
managing nitrogen in waste streams, ash pond management (with emphasis on
nitrogen and metals removal), dry and low water cooling technologies, non-oxidizing
biocides for cooling systems, plant water treatment, and constructed wetlands for waste
water treatment. Other responsibilities include program and project direction,

Dr. Robert G. Hoeft was raised on an irrigated grain and livestock farm in east central
Nebraska. He obtained his BSci and MSci from the University of Nebraska and his PhD
in soil science from the University of Wisconsin in 1972. Following graduation he was
employed as an Extension Agronomist at South Dakota State University until 1973
when he moved to the University of Illinois as an Assistant Professor of Extension and
Research-Soil Fertility. He progressed through the ranks to Professor in 1981. Dr.
Hoeft served as Coordinator of Agronomy Extension from 1977 to 2004 and Associate
Head of the Department of Crop Sciences from 2004-2005. In 2005, he was named
Head of the Department of Crop Sciences. Dr. Hoeft has devoted a major portion of
his research career to projects designed to evaluate factors influencing the efficiency of
nutrient use. His work with nitrification inhibitors provided classical data that allows
scientists and crop producers to make an informed decision on where these products
will likely be beneficial. His work on the effect of excess moisture on nitrogen loss now
allows producers to apply the proper rate of nitrogen knowing that they can utilize

-------
climatic data for the specific site to predict whether loss potential has been great
enough to justify supplemental application after periods of excessive rain. His work on
factors affecting immobilization and mineralization of nitrogen has brought a new
perspective to the importance of proper nitrogen management for optimum crop
production while maintaining environmental quality. Dr. Hoeft has expanded his
research program to include work on manure management and on factors affecting the
potential for phosphorus loss from agricultural soils. Results of this work have been
incorporated into nutrient management plan modules. He has authored 3 books, 7
book chapters, over 40 scientific journal articles and well over 200 professional and
popular articles. His research programs have clearly provided a data base for
individuals to utilize in designing nitrogen management programs that will optimize
production and minimize the potential for nitrogen to have an adverse impact on water
quality. Dr. Hoeft was the first Editor of the Journal of Production Agriculture and
served as President of the American Society of Agronomy, the largest agricultural
scientific society in the U.S. Dr. Hoeft's research has been funded by Illinois EPA,
