Welcome to the UTC Pipeline Safety GIS Map Viewer.
The Pipeline Safety GIS Map Viewer displays pipeline locations for individual counties in the state of Washington. The pipelines
displayed here includes hazardous liquid pipelines and high-pressure natural gas pipelines (>250 psig). The map viewer includes
ownership of the system and other general information. It does not contain gathering or distribution pipelines, such as line which
delivers gas to a customer's home. Pipelines of this type will not be displayed on the map.
Information displayed on the maps is for general purpose only and does not provide accurate information for
locating the pipeline, or other utilities such as power cable or lower pressure gas distribution pipelines. The data
provided should never be used as a substitute for contacting the one-call center prior to excavation activites.
Please call 811 before any digging occurs.
Please note that the viewer limits the scale of pipeline maps, in accordance with (PHMS's security policy). Pipeline features will
not display when the viewer is zoomed in closer than a 1:24,000 scale (approximately 0.2 miles on the scale bar).
