Transmission Pipeline Mapping
Want to know if any natural gas transmission pipelines are near you? The U.S. Department of Transportation’s Office of Pipeline Safety has developed the National Pipeline Mapping System (NPMS) to provide information about gas transmission and liquid transmission operators and their pipelines. The NPMS website is searchable by zip code or by county and state, and can display a county map that is printable.
For a list of pipeline operators with pipelines in your area and their contact information, go to www.npms.phmsa.dot.gov/. The NPMS should only be used for general pipeline overviews and should never be used as a replacement for calling 811 and having the utility companies mark the lines.
