Who regulates cloud seeding and weather modification activities? Are there potential effects?
The North American Weather Modification Council (NAWMC) indicates that, “Weather modification commonly referred to as cloud seeding, is currently used to increase precipitation from clouds, reduce hail from thunderstorms, and eliminate fogs that reduce visibility, usually at busy airports.” http://www.nawmc.org/4dcgi/GetCategoryRecord/FAQ's
State governments often license and regulate weather modification activities such as cloud seeding. For more information, contact the office in your state charged with managing water resources. You can obtain contact information for your regional environmental by selecting your state or territory in the following Web page: http://water.epa.gov/type/location/regions.cfm
Federal law requires most weather modification activities undertaken in the United States to be reported to the National Oceanic and Atmospheric Administration (NOAA). See 15 CFR 908 for details: http://www.gpo.gov/fdsys/pkg/CFR-2012-title15-vol3/pdf/CFR-2012-title15-vol3-part908.pdf.
In July, 2009, the Senate Committee on Commerce, Science, and Transportation endorsed the Weather Mitigation Research and Development Policy Authorization Act of 2009 [S. 601], which would "establish a Weather Mitigation Research Program (Program) within the National Science Foundation and authorize a research and development program to improve the understanding of processes relating to [weather modification activities]." For more information, see the bill's text at: http://www.gpo.gov/fdsys/pkg/BILLS-111s601is/pdf/BILLS-111s601is.pdf. The Committee's report, which references research conducted by the National Research Council (see below), is at: http://www.gpo.gov/fdsys/pkg/CRPT-111srpt57/pdf/CRPT-111srpt57.pdf.
