EPA SAB and BOSC joint recommendations on Implementation of ORD Strategic Research Plans
The EPA's Science Advisory Board (SAB) and the Executive Committee of the Office of Research and Development's (ORD) Board of
Scientific Counselors (BOSC) jointly offered comments and recommendations to the EPA Administrator on ORD's new strategic
research plans. ORD has realigned its research into six new program areas: Air. Climate and Energy; Safe and Sustainable Water
Resources (SSWR): Sustainable and Healthy Communities: Chemical Safety for Sustainabilitv: Human Health Risk Assessment: and
Homeland Security Research.
SAB and BOSC were supportive of the consolidation of EPA's research programs as part of an integrated transdisciplinary approach
to research that takes a systems approach to sustainability. They noted that ORD's Strategic Research Action Plans for its 6
research programs are important achievements that should help to clearly communicate ORD's new mission approach. The
report's summary points for SSWR were:
The Safe and Sustainable Waters program should identify and seek opportunities for leveraging research of other federal
agencies and engage with communities in setting the program's research priorities and research development. Program
linkages with sustainability, nutrient management and green infrastructure are critical to the success of this program.
The report provides further recommendations for all 6 research programs; many suggestions for other program areas (e.g.,
Chemical Safety for Sustainability) are also pertinent to OW's research and program needs. See the full report: Implementation of
ORD Strategic Research Plans: A Joint Report of the Science Advisory Board and ORD Board of Scientific Counselors. EPA-SAB-12-012.2012.

Ecological Systems Approach to Protect and Restore Sustainable
Water Quality and Water Quantity on a Watershed Basis
The President's Climate Action Plan
In June of this year, President Obama released his Climate Action Plan for the United States to:
Establish new rules and incentives to cut carbon pollution, including: directives to EPA to establish carbon pollution standards for
power plants; directives and goals for the Department of the Interior to provide renewables permits (wind, solar, hydropower);
expanded incentives and goals for development of innovative technologies and energy efficiency in appliances, motor vehicles, and
buildings; and other goals for reduction of greenhouse gases, including through protection of forests and critical landscapes.
Prepare for the impacts of climate change by: directing agencies to support local climate-resilience; piloting innovative strategies in
the Hurricane Sandy-affected region to strengthen communities against future extreme weather and other climate impacts;
launching efforts to create sustainable and resilient hospitals; providing information and tools to state and local leaders for climate
preparedness, including drought and wildfire preparedness.
Lead international efforts to address global climate change; to galvanize international action toward emission reductions, climate
impact preparedness, the plan: commits us to expanding new and existing international initiatives, especially with other major
emitting countries; calls for ending U.S. support for financing of new coal-fired powers plants overseas (with exceptions for
efficient technologies for the world's poorest countries, and for carbon capture and sequestration technologies); and expanding
government and local community planning and response capacities.

STREAMER Tool from USGS Lets You Navigate America's Major Rivers Without Getting Wet
STREAMER is a cool new on-line service from the USGS' National Atlas of the United States® that maps the routes of
America's major rivers and streams. The tool lets you pick a point on a stream and trace it downstream or upstream.
With STREAMER you can also:
• locate your area of interest with stream or place names, latitude and longitude coordinates, or ID number for a
USGS streamflow gaging station;
• find names of streams and waterbodies by clicking on them;
• print maps and create reports for your upstream and downstream traces;
• learn about streamflow at thousands of locations along America's streams, with just a few mouse clicks.
The National Atlas of the United States of America® is a cooperative effort to make geographic information collected by the
United States government easier to find, get, and use. Its development is led by the National Geospatial Program of the USGS.
