The Department of Environmental Protection Thursday announced Sunoco Pipeline, L.P. has satisfied requirements under the July 24, 2017 Consent Order and Agreement which suspended horizontal directional drilling at Shoen Road Drill 360 (Shoen Road drill) as part of Sunoco’s Mariner East II Project.

DEP and Sunoco entered into the COA after work at the Shoen Road drill impacted water supplies at locations in West Whiteland and Uwchlan Townships, Chester County. DEP has since reviewed Sunoco’s request to restart this drill, including information submitted in support of the request and actions taken in response to the COA.

DEP has approved the Water Supply Restoration Plan required under the agreement and finds that Sunoco has satisfied the terms of the COA.

Sunoco can commence drilling after providing the required notices to DEP, the Townships, and landowners with water supplies within 450’ of the Drill, and receiving written authorization from DEP. 

Sunoco is still subject to other enforcement actions and requirements separate from this COA, and must demonstrate that it has given landowners along the pipeline corridor advance notice in accordance with the requirements of the August 9, 2017 Stipulated Order notice prior to restarting. 

DEP retains the right to assess further penalties on this matter. 

For more information on the project, including a full copy of the July 24th Consent Order and Agreement, please visit DEP’s Mariner East II Pipeline webpage.
