National Public Radio is reporting that legal challenges could delay a natural gas liquids line proposed by Sunoco Logistics. "Sunoco Logistics has asked the state’s Public Utility Commission to declare its Mariner East pipeline a public utility, thus allowing the company to sidestep local zoning laws to build pump and valve stations along the pipeline’s 300-mile route. *** Several groups, including environmental organizations, have filed formal objections with the PUC opposing Sunoco’s claims that it is a public utility corporation." Quoting the Inquirer: "A hearing before the five-member PUC 'will not happen by the end of the summer,' said Jennifer Kocher, the PUC’s spokeswoman. And any PUC decision could be further delayed by appeals to the Commonwealth Court."
