A Pennsylvania Environmental Hearing Board judge Thursday turned down a request that he reconsider a decision allowing Sunoco Logistics Partners to begin construction of the Mariner East 2 pipeline.

Judge Bernard A. Labuskes Jr. rejected a request by three environmental groups to reconsider last week's ruling, in which he declined to block permits issued  by the state Department of Environmental Protection that would allow Philadelphia-based Sunoco Logistics to start construction of a cross-state pipeline to deliver Marcellus Shale propane to Marcus Hook.

Labuskes said the environmental groups, led by the Clean Air Council, did not present any new information to justify an emergency block on the permits. He has scheduled a hearing starting March 1 to hear the environmental groups' arguments that DEP's review process was flawed. But with the permits in hand, Sunoco Logistics has begun construction of the new pipeline.
