The cross-state natural gas liquids pipeline Mariner East 2 was supposed to begin operation by the end of September. Now, the company has come up with a workaround after acknowledging another lengthy delay in its pipeline project.
Pipelines: The new battleground over fracking
Pipeline wars are raging in Pennsylvania, where production is high and pipeline capacity is low. Marcellus Shale gas has the potential to alter the landscape of the global energy market. But right now, a shortage of pipelines to get that gas from the wellheads to consumers means rock bottom prices for producers, who are eager to dig new trenches. Activists opposed to more drilling see pipeline construction as the new battleground over fracking.
In our six-part series on Pennsylvania’s pipeline building boom, StateImpact examines who wins and who loses in the next phase of the natural gas rush.
Pennsylvania’s pipeline building boom could expand the nation’s and perhaps the world’s, supply of natural gas. This boom includes an estimated 4,600 miles of new interstate pipes, tunneling under Pennsylvania’s farms, wetlands, waterways, and backyards.
Pipeline companies know exactly the routes for all the pipelines they maintain or plan to build, but they aren’t required to share that information with the public in a post-9/11 world. Even when it comes to interstate pipelines, the large ones that carry lots of gas at high pressure across multiple states, those are only required to be mapped within 500 feet of accuracy.
Pennsylvania expects the industry to add 20-25,000 miles of gathering lines, which are pipelines that take gas from wellheads to a larger transmission line or gas processing facility. Most of these so-called “class one” lines will be in rural areas and no state, federal or local authority oversees them. This lack of regulation can lead to dangerous consequences.
Industry says these large interstate pipelines will benefit rate-payers, especially those in areas where energy costs are high like New York and Boston, and feed cleaner-burning fuel to large East Coast power plants. But the lines cut through areas of rare open space in New Jersey, where land has been preserved with public dollars, forcing residents to weigh the environmental costs of moving natural gas to the marketplace.
Pipeline builders also say local communities will benefit from new jobs and tax dollars. But those tax benefits aren’t equal across state lines and while New Jersey could reap millions of dollars a year in new revenue, Pennsylvania could be leaving millions of dollars on the table.
Local communities across the state increasingly see themselves as the losers. Faced with little influence over interstate pipeline construction, some are trying to stop the surge in oil and gas development by embracing a novel legal tactic: community-based rights ordinances. It’s a strategy that carries risks.
The company missed its deadline of opening the line by the end of September. The Public Utility Commission said there are several issues with the project that still need to be resolved.
As part of the “Mariner East 2: At what risk?” series, StateImpact Pennsylvania reports how pipeline opponents say Sunoco’s construction makes them worried about the volatile liquids flowing through the line. The data can be useful, but there may be more to the story, two experts said.
As part of the “Mariner East 2: At what risk?” series, StateImpact Pennsylvania reports how firefighters are trained to respond to a pipeline explosion, though shutting the line down would be the company’s responsibility. Energy Transfer Partners says most of Mariner East 2’s valves can be controlled remotely.
The Delaware River Basin Commission said it thinks the company might want to start clearing trees before its project gets all necessary approvals. In part, the commission is worried about problems that could occur if the pipeline never gets built.
The study says a pipeline “release” such as a small leak or a major rupture was likely to occur once every 79 years along a 35-mile stretch of pipeline such as that through Chester and Delaware counties.
The company said the work in Delaware County is a preventative measure. An independent pipeline consultant said it’s ‘rare’ that a line is dug up and replaced like this.
