# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Notice of public comment period.

# SUMMARY:

The EPA is announcing a 60-day public comment period for the draft document titled, “A Method to Assess Climate-Relevant Decision: Application in the Chesapeake Bay” (EPA/600/R-10/096a). The draft document was prepared by the National Center for Environmental Assessment (NCEA) within EPA's Office of Research and Development.

                        In the 2010 Executive Order (EO) Strategy entitled,                         *Protecting and Restoring the Chesapeake Bay Watershed,*                         EPA has committed to “minimize the vulnerability of the Chesapeake Bay watershed to adverse impacts from climate change.” The EO Strategy also commits EPA to ensuring that “TMDL allocations account for climate change impacts [by working] in conjunction with the states to conduct an analysis by 2017 to consider accounting for uncertainties of climate change in TMDL allocations.” To accomplish this, it is necessary to understand the rates at which conditions are changing and are projected to change in the future; how various factors, such as land-use changes, interact with climate change impacts; and the likely consequences for water quality, habitats, fish and wildlife and communities. This draft report presents a systematic approach for evaluating these factors and practices for their relative potential effectiveness in ameliorating climate changes impacts. The report also includes the results of applying this approach in a pilot assessment of management practices in the Chesapeake Bay watershed. The practices evaluated could be used for both nutrient and sediment reductions, and also to ameliorate the effects of climate change on water quality that will ultimately inform the 2017 reassessment for Bay restoration.                    

                        The public comment period and the external peer-review workshop, which will be scheduled at a later date and announced in the                         **Federal Register**                        , are separate processes that provide opportunities for all interested parties to comment on the document. EPA intends to forward public comments that are submitted in accordance with this notice to the external peer-review panel prior to the meeting for their consideration. When finalizing the draft document, EPA intends to consider any public comments that EPA receives in accordance with this notice.                    

EPA is releasing this draft document solely for the purpose of pre-dissemination peer review under applicable information quality guidelines. This document has not been formally disseminated by EPA. It does not represent and should not be construed to represent any Agency policy or determination.

# DATES:

The 60-day public comment period begins August 31, 2010, and ends November 1, 2010. Technical comments should be in writing and must be received by EPA by November 1, 2010.

# SUPPLEMENTARY INFORMATION:

## I. Summary of Information About the Project/Document

Climate change is a global phenomenon that is affecting natural and human systems in all parts of the world. Some of the decisions and actions taken to manage these systems are likely to be affected by climate change and may likewise affect the vulnerability of the managed resource or ecosystem to climate change. The goal of this study is to formalize an approach to inventory and analyze management decisions in order to produce useful information targeted toward effective adaptation to climate change. The approach uses as its starting point ongoing planning processes and decisions geared toward achieving environmental management goals, and then collects information on decisions and prioritizes them according to specific attributes. The pilot study described in this report applies this approach and examines its usefulness to decision makers.

The major steps of the approach are to (1) select a study area and compile a list of key decisions (2) develop criteria for evaluating the climate-relevance of decisions; (3) apply the criteria to select decisions that are potentially sensitive to climate change; (4) solicit expert judgment regarding those selections (and refine the selections accordingly); and (5) test alternative weighting schemes for prioritizing decisions most in need of decision support or additional research based on the selected attributes.
