Sunoco Logistics has been given the green light to resume drilling for the Mariner East 2 pipeline after the company reached a settlement with state officials and environmental groups in Pennsylvania.
Sunoco has agreed to re-evaluate high-risk sites associated with its 350-mile pipeline project, according to the agreement.
The company plans to re-evaluate 47 high-risk sites and submit the drilling plans of those sites to the Pennsylvania Department of Environmental Protection for approval. The re-evaluations will also be posted online.
Sunoco said it will also send the plans to homeowners who have private wells near the drilling sites and will offer opportunities to have their water tested.
Drilling for the pipeline had tainted the wells of close to 30 residences in West Whiteland Township, Pennsylvania back in July.
The settlement came one day before a scheduled hearing with Pennsylvania's Environmental Hearing Board on a petition to halt all drilling. The hearing was postponed to a future date pending a review by the environmental board.
The $2.5 billion Mariner East 2 pipeline would carry propane, butane, and ethane from the Marcellus Shale natural gas formation to an export terminal near Philadelphia.
