No change to in-service date

October 22, 2018 —We want to clarify that there has been no change to the initial in-service date for the Mariner East 2 pipeline (ME2). Our timelines have not changed. Unfortunately, a local Pennsylvania reporter misconstrued the temporary use of a section of an existing 12-inch line to get initial service on ME2.  The line will be in service as soon as it is mechanically complete, which we expect to be shortly.

Mariner East: $9.1 Billion in the Pipeline

Our people and our facilities throughout Pennsylvania have been contributing to the state’s economy for more than a century, most recently through the expansion of our Marcus Hook facility as part of Mariner East 1 and Mariner East 2 pipeline projects.

The economic impact study released Jan. 8 by Econsult Solutions shows the importance of this project to our state’s economy, not only to the thousands of local tradespeople who are earning family-sustaining wages and spending their money in the community but to the hundreds of local companies providing goods and services to those workers, their families, and their companies.

This is what happens when you invest $5 billion in Pennsylvania. The completion of the Mariner East 2 pipeline will only create more opportunities for investment and local job creation in the state.
