Pennsylvania’s Department of Environmental Protection (DEP) ordered Sunoco Pipeline LP to stop construction of the Mariner East 2 natural gas liquids pipeline until it meets requirements in an order the agency issued.

Pennsylvania’s Department of Environmental Protection (DEP) ordered Sunoco Pipeline LP to stop construction of the Mariner East 2 natural gas liquids pipeline until it meets requirements in an order the agency issued. The Jan. 3order covers all activity on the project except for maintenance of erosion controls and limited maintenance of directional-drilling equipment, DEP said.

“Until Sunoco can demonstrate that the permit conditions can and will be followed, DEP has no alternative but to suspend the permits,” DEP Secretary Patrick McDonnell said. The agency noted that all activity authorized under the permits must cease until Sunoco Pipeline:

● Addresses all impacts to private water wells in Silver Spring Township, Cumberland County.

● Identifies all in-progress or upcoming construction and specify its authorization.

● Submits a detailed operations plan outlining additional measures and controls to minimize inadvertent releases.

Sunoco Pipeline, formed when Energy Transfer Partners and Sunoco Logistics Partners merged in April 2017, immediately issued a statement saying it would submit the required reports expeditiously.
