DEP grants permits for Sunoco Logistics pipeline

Pennsylvania environmental regulators on Monday approved permits for a $2.5 billion natural gas liquids pipeline project traversing 17 counties across the southern tier of the state.

The state Department of Environmental Protection granted Sunoco Logistics Partners 20 water crossing and erosion permits for the Mariner East 2 pipeline that will bring natural gas liquids from Ohio and southwestern Pennsylvania’s Marcellus and Utica shale fields to a terminal in southeastern Pennsylvania for domestic use or export.

The project — which has drawn an extraordinary amount of public feedback in support and opposition — includes up to two new, 350-mile-long pipelines that will generally run parallel to Sunoco’s existing Mariner East 1 pipeline.

The new lines will carry propane, butane and ethane and are expected to have an initial capacity of 275,000 barrels per day.

Acting DEP Secretary Patrick McDonnell said the evaluation was “a huge undertaking” that included “reviewing permit applications and technical deficiencies for more than 20,000 hours, responding to 29,000 comments, and ensuring Sunoco addressed deficiencies identified in its initial applications.”

Sunoco has said it expects the project will be completed in the third quarter of 2017.
