More Shipping Channel Troubles for Gulf Coast LNG Exports
Last week MDN told you about a barge sinking in a shipping channel in Lousiana that had contributed to a big drop in the price of natural gas (see Sunken Barge in LA Helps Fuel $0.22 One-Day Drop in NatGas Price). That barge is still stuck on the bottom, blocking traffic to the Cameron LNG facility. In addition to trouble for Cameron in the Calcasieu Ship Channel, a semi-submersible rig ran aground in the Sabine Bank Channel, blocking LNG traffic to and from Cheniere Energy’s Sabine Pass LNG terminal.

A few weeks ago Enbridge began testing its Weymouth, Massachusetts compressor station project, the final piece of the company’s $452 million Atlantic Bridge expansion project. As sometimes happens when you begin testing, there was a problem. A gasket failure led to an unplanned release of 265 Mcf of gas (see 
It could have been avoided. The Pennsylvania Dept. of Environmental Protection (DEP) has no one to blame but themselves for what happened at Marsh Creek Lake in Chester County, PA, when Energy Transfer (ET), drilling underground to install a pipeline for the Mariner East 2 project, experienced a drilling mud spill in August (see 
Sunoco Logistics Partners (i.e. Energy Transfer) was drilling horizontally underneath Snitz Creek in Lebanon County, PA for its Mariner East 2 Pipeline project when it experienced yet another “inadvertent return”–nontoxic drilling mud leaking out of a place where it shouldn’t. In 2018 the same thing happened and antis blew a gasket over a “spill” of five gallons (see 
Two weeks ago while drilling in Chester County in Marsh Creek State Park, Energy Transfer’s Mariner East (ME) 2X pipeline experienced an “inadvertent return”–nontoxic drilling mud coming up out of the ground where it’s not supposed to (see 
While drilling in Chester County earlier this week in the Marsh Creek State Park, Energy Transfer’s Mariner East 2X pipeline experienced an “inadvertent return”–nontoxic drilling mud coming up out of the ground where it’s not supposed to (see 
Underground horizontal directional drilling (HDD) for the Mariner East 2 pipelines (two of them, 2 and 2X) have a history of springing leaks. They’re called “inadvertent returns”–when you drill horizontally underground for a pipeline and the drilling mud you put down the hole pops up in a place it’s not supposed to. The good news is that the drilling mud is non-toxic, the same stuff used in toothpaste. The bad news is that it can overwhelm little fishies and other aquatic life and kill (suffocate) them. ME2X drilling had another such incident earlier this week–in Chester County, PA.
On August 1, 2019, Enbridge’s Texas Eastern Pipeline Company (TETCO) pipeline exploded in Lincoln County, Kentucky–killing one and sending six to the hospital (see 
On Friday the Pennsylvania Dept. of Environmental Protection (DEP) announced it has fined CNX Resources and its subsidiary CNX Midstream $310,000 for two incidents in which 65 barrels (2,730 gallons) of non-toxic brine (salty water) leaked into the ground and 43 gallons of non-toxic drilling mud leaked into a creek. The DEP says CNX did “not adequately maintain erosion and sedimentation best management practices.”
Energy Transfer’s subsidiary Sunoco Logistics is trying to finish up final construction of the Mariner East 2X pipeline in southeast Pennsylvania. ME2 and ME2X flow natural gas liquids including ethane and propane from eastern Ohio and western PA all the way to the Marcus Hook refinery near Philadelphia. As the pipe travels through Philly neighborhoods, some of the geography is limestone (porous) and when drilling to install pipes, it has led to sinkholes. Another seven such sinkholes have appeared since June and the state Public Utility Commission (PUC) is investigating.
Columbia Gas of Massachusetts (NiSource) never quite recovered (reputationally) from a series of explosions in September 2018 that occurred with its local delivery pipelines north of Boston (see
