NOTE: RESTRICTED DATA. This dataset comprises Unusually Sensitive Areas (USAs) data for drinking water resources in the state of Wyoming. Complex polygons in this dataset represent locations of USAs for drinking water resources. In accordance with pipeline safety laws (49 U.S.C. Section 60109), the Pipeline and Hazardous Materials Safety Administration (PHMSA) is required to identify areas unusually sensitive to environmental damage in the event of a hazardous liquid pipeline accident. Through interactions with various regulatory agencies, pipeline operators, private contractors, and the general public, a process has been developed and adopted by PHMSA to identify USAs for drinking water resources (refer to the...

NOTE: RESTRICTED DATA. This dataset comprises Unusually Sensitive Areas (USAs) data for ecological resources in the state of Wyoming. In accordance with pipeline safety laws (49 U.S.C. Section 60109), PHMSA is required to identify areas unusually sensitive to environmental damage in the event of a hazardous liquid pipeline accident. Through interactions with various regulatory agencies, pipeline operators, private contractors, non-profit conservation organizations, and the general public, a process has been developed and adopted by PHMSA to identify USAs for ecological resources. The process consists of identifying a set of candidate ecological resources using approved data sources, and subjecting candidates to...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
