Another sinkhole developed last Friday near Philadelphia related to underground drilling done to install the Mariner East 2 pipeline. The new sinkhole developed in Middletown Township (Delaware County), in Sleighton Park. Fortunately this latest hole was only about 18 inches in diameter, which is much better than a 15×15 foot hole that developed in September, also in Middletown Township (see Another Mariner East 2 Pipe Sinkhole Opens in Delaware County). However, the 18-inch hole fanned out to four feet wide and 30 feet deep underground. Sunoco immediately filled it with “flowable fill” (i.e. concrete)–to the tune of 48 yards of material.

The Pennsylvania Dept. of Environmental Protection (DEP), which once supported (in court) Sunoco Logistics Partners method of requesting permits for the Marcus Hook facility (near Philadelphia), has just flip flopped and change sides, now siding against Sunoco and the permits the DEP itself issued for the Marcus Hook facility. DEP is now siding with the radical Clean Air Council demanding that all of the work at the Marcus Hook facility be done under a single emissions permit, not separate permits.
The actions of one man seeking access to confidential risk assessments and plans for the Mariner East pipelines in the Philadelphia area will, if successful, put information into the public domain that terrorists can potentially use. Note we don’t believe it is the intent of this man to grant access to sensitive information to terrorists.

We spotted a story about landowners in the Philadelphia suburbs who currently have to live with construction of the Mariner East 2 pipelines (plural, there are two of them, ME2 and ME2X), literally happening in their back yards. While we are strong supporters of the ME2 project, we are not unsympathetic to landowners and the hassles they have to endure while it’s being built.
Ever notice how predators like to hunt in packs? First the Chester County, PA District Attorney launched an ethically questionable “investigation” into “crimes” that may have been committed by building the Mariner East pipelines through his county (see 
In November seven anti-pipeline residents of Chester and Delaware counties (Philadelphia suburbs) filed a lawsuit against the Mariner East pipeline projects–1, 2 and 2X–alleging the pipelines are unsafe. It didn’t take long for others to jump on the litigation bandwagon:
According to RBN Energy, “U.S. production of natural gas liquids is projected to increase by 17% this year, and by another 10% in 2020.” NGLs cover a variety of hydrocarbons. Two NGLs, propane and butane, are further classified as LPG–or liquefied petroleum gas. Of the four “smaller” LPG export facilities here in the U.S., two-thirds of all exported LPGs last year came from one–Energy Transfer’s Marcus Hook refinery near Philadelphia.
