This program shall coordinate federal efforts to improve the assessment of fire environments and the understanding and prediction of wildland fires, associated smoke, and their impacts; develop and encourage the adoption of science-based and cost-effective measures to prevent and mitigate wildland fire and associated smoke impacts; and improve the understanding and mitigation of the impacts of climate change and variability on wildland fire risk, frequency, and severity and inform the other goals described here. Not later than 90 days after enactment of this bill, the Office of Science and Technology Policy shall establish an Interagency Coordinating Committee on Wildland Fire Risk Reduction to oversee the planning, management, and coordination of the program. The committee shall submit a strategic plan for the program to Congress. The Government Accountability Office shall submit a report to Congress on the progress and performance of the program. Further, the bill sets forth the responsibilities of the National Institute of Standards and Technology, National Science Foundation, National Oceanic and Atmospheric Administration, Federal Emergency Management Agency, National Aeronautics and Space Administration, Environmental Protection Agency, and Department of Energy with respect to the program.
