Adelphia Gateway FAQs

Safety Fact Sheet


Natural gas pipelines have a strong safety record of transporting products that are essential to our daily lives and the energy demands of today’s world. In fact, pipeline systems are the safest and most efficient means to move energy, according to National Transportation Safety Board statistics.

Safety is a top priority for Adelphia Gateway. The pipeline adheres to industry safety standards, as well as guidelines set forth by the U.S. Department of Transportation (U.S. DOT) Pipeline and Hazardous Materials Safety Administration and the Federal Energy Regulatory Commission.

The pipeline, previously owned by Interstate Energy Company LLC, was originally constructed in the 1970s and transported oil from Marcus Hook to Martins Creek. In 1996, the northern 34 miles of the pipeline were converted to transport natural gas. The southern 50-miles were converted in 2022. New laterals and interconnections with other utilities were also added to increase natural gas access in the region.

The pipeline operates at a maximum allowable operating pressure (MAOP) of 1,083 pounds per square inch gauge. The pipeline has been hydrotested and is regularly inspected to confirm its integrity.

Pipeline Markers

Pipeline markers are important for the safety of the public and provide emergency responders with critical information. The markers display the product transported through the pipeline, the name of the pipeline operator and a telephone number, in the event of an emergency.

Pipeline markers placed along the route, and at key intersections, indicate approximately where pipelines are located, not necessarily the depth of the pipe. It is crucial to call 811 before you dig to prevent damage to underground structures. Adelphia Gateway will participate in the Pennsylvania One Call program to work with homeowners, project owners, excavators and utilities to ensure the pipeline is safe.

Maintaining Safety and Integrity

At Adelphia Gateway, the safety of our employees and the community is our top priority. We are committed to maintaining the quality and integrity of the pipeline.
