Pennsylvania Relies on Energy.

We Deliver It Safely.

The Mariner East pipeline system provides the needed infrastructure to transport natural gas liquids (NGLs), including propane, ethane and butane, from the Marcellus and Utica Shale fields to markets in Pennsylvania and beyond.

Now fully operational, the Mariner East system continues to support hundreds of family-sustaining jobs and provide a safer means to deliver NGLs that are integral to our everyday lives.

Energy Transfer is committed to safety at the highest level. The safety of our employees and the community is our highest priority, and we believe no project is worth doing if it cannot be done safely.

We are #Committed2PA

As part of our continued efforts in Pennsylvania, we remain committed to:

Making Everyday Life Possible

Although most people are familiar with the well-known uses of natural gas and NGLs, such as heating and cooking with propane, few are aware of the truly diverse uses of these products and byproducts in our everyday lives.

Byproducts of NGLs such as propane, butane and ethane are used as the raw materials that manufacturers rely on to make plastics and other pliable and durable materials.

Food packaging, adhesives, sealants, refrigerants, automotive parts, aerosols, carpeting, clothing, medical devices, electronics and so much more would not be possible without natural gas and NGLs. 

In fact, the COVID-19 immunization effort relied on the oil and natural gas industry to ensure vaccines could be distributed quickly and safely. Dry ice and refrigeration were vital to keeping vaccines cold and viable. Syringes, PPE and other plastic medical supplies were vital to keeping health care workers safe when administering vaccines.

For all intents and purposes, our world would look a lot different without these byproducts.

Working together to deliver safe energy

Energy Transfer coordinates training with first responders across Pennsylvania

At Energy Transfer, safety is not just a slogan — it’s our culture. We developed a Mariner Emergency Responder Outreach Program (MERO) in which we meet with first responders in all the counties we pass through to train them on the products we transport and assist them in refining their own emergency response plans.

These sessions are in addition to the annual Pennsylvania Pipeline Awareness and Emergency Response Training for emergency officials, public officials and excavators scheduled throughout

Pennsylvania, and numerous emergency preparedness meetings held in collaboration with school districts along the pipeline route.
