Several environmental groups have asked the Commonwealth Court for an injunction to halt Sunoco/Energy Transfer Partners’ Mariner East 2 pipeline construction.
The Clean Air Council, along with the Delaware Riverkeeper Network, and Mountain Watershed Association, say a settlement reached between Sunoco and the Department of Environmental Protection earlier this month amounts to a breach of contract reached by all parties last summer.
It’s the latest legal challenge to the controversial natural gas liquids pipeline, which has faced opposition from landowners challenging eminent domain, and residents frustrated by dozens of environmental violations.
