The U.S. Department of Transportation's Office of Pipeline Safety has developed the National Pipeline Mapping System (NPMS) to provide information about pipeline operators and their pipelines. The NPMS website is searchable by zip code or 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.

Natural Gas distribution mains and service lines are not shown on the NPMS website.
