Note: Beginning in July 2008, there will be a gap in the availability of the Substance Registry System (SRS) web services. EPA's Office of Environmental Information (OEI) has redesigned the SRS and plans to make the new version available on July 11, 2008. EPA will be building updated web services that are compliant with this new version of SRS as well as Node 2.0. The new SRS web services are scheduled for production release in September 2008.
If you would like to learn more about the new functionalities available in the redesigned SRS or learn more about the SRS web services, please contact John Harman at 202-566-0748 or visit http://www.epa.gov/srs
data exchange description
This data exchange allows states to use web services to access data from the Substance Registry System (SRS). The SRS is the U.S. Environmental Protection Agency's (EPA) central system for information about regulated and monitored substances. The system provides a common basis for identification of chemicals, biological organisms, and other substances listed in EPA regulations and data systems, as well as substances of interest from other sources, such as publications. The SRS supports and conforms to EPA's Chemical Identification Data Standard and the EPA's Biological Identification Data Standard. The SRS is a part of the centralized System of Registries (SoR), which provides access to the Agency's core registry systems.
