Pipeline Information Center


The Chester County Commissioners have launched an informational website–the Pipeline Information Center–about the 600 miles of pipeline infrastructure in Chester County.  It provides a wide range of information on proposed pipeline projects and operators, regulatory agencies, the regulatory process, pipeline maps, and other pipeline resources.  The interactive pipeline map allows anyone in the county to enter their address and determine their proximity to existing pipelines.

Resources are also provided to aid in the location of pipelines easements and deed information.  As noted on the webpage, this information is not a substitute for legal advice and any financial or legal decisions should only be made after consulting with an experienced professional adviser.  Click here for the landowners’ resources page.
