How do operators obtain information about the location of high consequence areas now that National Pipeline Mapping System (NPMS) information is no longer publicly available on the internet?
The pipeline and unusually sensitive area data layers are no longer available for download from the NPMS homepage. Operators are able to obtain the data by contacting PHMSA Pipeline Safety directly. Instructions on requesting the information are available on the NPMS data download page. (http://www.npms.phmsa.dot.gov/data/data_dissem.htm). PHMSA Pipeline Safety will only provide back to the operator a copy of their pipeline system and not a copy of all pipelines in NPMS. High Population Areas, Other Populated Areas, and Commercially Navigable Waterways are available for download from the NPMS data download web page.
