The Pennsylvania Department of Environmental Protection fined sunoco more than 12 million for various permit violations. But it also cleared the way for digging to resume. And residents are outraged. As you can see, the mariner east 2 pipeline runs right through town. And through some of the most densely populated parts of the state.

Residents point to independent risk analysis funded by a group of private citizens and it concluded a leak of highly pressurized liquid gas could result in a vapor cloud that could spread 100 feet within three minutes burning any one within 700 feet. You have off to evacuate on foot. Because you cant start a vehicle. You cant use your cell fen to call for help. Those things can set off the gas. An impossible task.
