Vulnerability Assessments in Support of the Climate Ready 
Estuaries Program: A Novel Approach Using Expert Judgment, Volume I: 
Results for the San Francisco Estuary Partnership and Volume II: 
Results for the Massachusetts Bays Program

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of Public Comment Period and Letter Peer-Review.

-----------------------------------------------------------------------

SUMMARY: EPA is announcing a 30-day public comment period for the draft 
documents titled, Vulnerability Assessments in Support of the Climate 
Ready Estuaries Program: A Novel Approach Using Expert Judgment, Volume 
I: Results for the San Francisco Estuary Partnership (EPA/600/R-11/
058a) and Vulnerability Assessments in Support of the Climate Ready 
Estuaries Program: A Novel Approach Using Expert Judgment, Volume II: 
Results for the Massachusetts Bays Program (EPA/600/R-11/058b). The EPA 
also is announcing that Eastern Research Group, an EPA contractor for 
external scientific peer review, will select two independent groups of 
experts to conduct a letter peer-review of the same draft documents. 
The documents were prepared by the National Center for Environmental 
Assessment within EPA's Office of Research and Development, in 
collaboration with the San Francisco Estuary Partnership (SFEP), the 
San Francisco Bay Conservation and Development Commission, and the 
Massachusetts Bays Program (MBP). The reports are pilot ecological 
vulnerability assessments using a novel methodology, based on expert 
judgment, to inform adaptation planning under EPA's

[[Page 55674]]

Climate Ready Estuaries Program. To demonstrate the novel methodology, 
two ecosystem processes were selected for each assessment: sediment 
retention in salt marshes (for both SFEP and MBP) and community 
interactions (of wading shorebirds and their mudflat prey for SFEP, and 
of the saltmarsh sharp-tailed sparrow and key species of nesting 
habitat grasses for MBP). This study assesses (1) Relationships among 
key physical and ecological variables that regulate each process, (2) 
relative sensitivities of these relationships under current and future 
climate change scenarios, (3) degree of confidence about these 
relationships, and (4) implications for management. The results of this 
study are designed to support the SFEP's and MBP's adaptation planning 
efforts as well as those of other estuary managers.
    EPA intends to forward the public comments that are submitted in 
accordance with this notice to the external peer-reviewers for their 
consideration during the letter review. When finalizing the draft 
document, EPA intends to consider any public comments received in 
accordance with this notice. EPA is releasing these draft documents for 
the purpose of pre-dissemination peer review under applicable 
information quality guidelines. These documents have not been formally 
disseminated by EPA. They do not represent and should not be construed 
to represent any Agency policy or determination.
    The draft documents are available via the Internet on the NCEA home 
page under the Recent Additions and the Data and Publications menus at 
http://www.epa.gov/ncea.

DATES: The 30-day public comment period begins September 8, 2011, and 
ends October 11, 2011. Technical comments should be in writing and must 
be received by EPA by October 11, 2011.

ADDRESSES: The two draft documents, Vulnerability Assessments in 
Support of the Climate Ready Estuaries Program: A Novel Approach Using 
Expert Judgment, Volume I: Results for the San Francisco Estuary 
Partnership and Vulnerability Assessments in Support of the Climate 
Ready Estuaries Program: A Novel Approach Using Expert Judgment, Volume 
II: Results for the Massachusetts Bays Program, are available primarily 
via the Internet on the National Center for Environmental Assessment's 
home page under the Recent Additions and the Data and Publications 
menus at http://www.epa.gov/ncea. A limited number of paper copies are 
available from the Information Management Team, NCEA; telephone: 703-
347-8561; facsimile: 703-347-8691. If you are requesting a paper copy, 
please provide your name, mailing address, the EPA number of the 
requested publication, and the document title, Vulnerability 
Assessments in Support of the Climate Ready Estuaries Program: A Novel 
Approach Using Expert Judgment, Volume I: Results for the San Francisco 
Estuary Partnership or Vulnerability Assessments in Support of the 
Climate Ready Estuaries Program: A Novel Approach Using Expert 
Judgment, Volume II: Results for the Massachusetts Bays Program.
    Comments may be submitted electronically via http://www.regulations.gov, by mail, by facsimile, or by hand delivery/
courier. Please follow the detailed instructions provided in the 
SUPPLEMENTARY INFORMATION section of this notice.

SUPPLEMENTARY INFORMATION:

I. Information About the Project/Document

    For this project, an exercise was designed to elicit judgments from 
experts in a workshop setting, regarding climate change effects on two 
ecosystem processes for each pilot assessment: sediment retention and 
community interactions. This method is based on a novel application of 
expert elicitation (a process for obtaining the judgments of groups of 
experts to characterize each expert's beliefs about relationships of 
interest) for use in a two-day workshop using two groups of seven 
expert participants each. EPA has investigated the utility of expert 
elicitation and provides recommendations for ``best practices'' through 
an Expert Elicitation Task Force White Paper (see http://www.epa.gov/spc/expertelicitation/index.htm).
    The exercise involved elicitation of qualitative judgments about 
the sensitivity of ecosystem processes to physical and ecological 
variables, using ``influence diagrams'' to depict the relationships 
among variables. For each ecosystem process, an influence diagram was 
developed that identified the key process variables and their 
interrelationships (influences). Using a coding scheme, each expert 
characterized the type and sensitivity of each influence under both 
current and future climate change scenarios.
    The experts also discussed the high impact of certain influences on 
sediment retention and community interactions, relative to other 
influences in the diagram, and the potential for threshold changes.
    These reports show how climate-sensitive pathways can be identified 
and linked to management options in the context of planning documents 
in order to support adaptation to climate change.
