Mariner East Pipeline Construction Update

In February, the Pennsylvania Department of Environmental Protection issued the necessary permits for
Sunoco Logistics’ Mariner East 2 pipeline project, an energy infrastructure system that is critical to
Pennsylvania’s economic future. In a comprehensive process spanning more than 2 ½ years – one that
included unprecedented public input — Sunoco Logistics provided detailed plans to minimize impacts to the
environment, protected species and cultural resources.
Construction of our Mariner East 2 system continues across the project footprint in accordance with all permits
and relevant regulations. Construction crews from eastern Ohio to southeastern Pennsylvania are working
safely, inspectors are working daily with construction teams to ensure we are protecting environmental and
cultural resources, and highly skilled laborers are ensuring safe pipeline installation.
Mariner East 2 consists of two new pipelines — a 20 inch pipeline and and 16 inch pipeline — approximately 350
miles in length that will transport propane, butane and ethane from the Marcellus and Utica shale areas of
Ohio, West Virginia and Western Pennsylvania eastward to the Marcus Hook Industrial Complex in
Southeastern Pennsylvania. Both pipelines will be installed as part of one construction project to minimize
disturbance to landowners and the environment.
Sunoco Logistics anticipates that construction of the 20 inch pipeline will be completed by the end of the third
quarter 2017 and construction of the 16 inch pipeline will be completed by the end of the first quarter 2018.
The Mariner East 2 system will be built and operated to standards that meet and in many cases exceed federal
pipeline safety regulations, using 75,000 tons of steel pipe, 100 percent made in America.
Pennsylvania’s future as an energy and manufacturing center has never been brighter, and Sunoco Logistics is
proud to be part of it.
