With the program review process that is described, states and tribes can develop a plan to build on their program strengths and address the limitations. Go to Report or www.epa.gov 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.

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.

Go to Report 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.
