Offer to Relocate Families Near ME2 Sinkholes; ME1 Down Until May?

Sinkhole in Chester County, PA

Sunoco Logistics Partners (aka Energy Transfer Parnters) has had its challenges in constructing the twin Mariner East 2 (ME2) pipelines across Pennsylvania. In March, MDN told you that underground horizontal directional drilling (HDD) work in Chester County had led to a third sinkhole developing in that area (see 3rd Sinkhole Appears Near ME2 Construction in Chester County, PA). For most of its length, ME2 is being built next to the existing ME1 (Mariner East 1), a liquids pipeline originally built in 1931. The third sinkhole in Chester County exposed a portion of ME1, leading to the state Public Utility Commission “temporarily” shutting down ME1 on March 7 (see PA PUC Shuts Down Mariner 1 Pipeline Due to Mariner 2 Sinkhole). ME1 would be, according to Sunoco, out of commission for “10 to 14 days.” Nearly a month later it’s still not running and until the state Dept. of Environmental Protection gets solid answers about the sinkholes, it won’t restart. It now looks like ME1 won’t be operational again until May. ME1’s closure has put several shippers, primarily Range Resources, in a bind (see Range, CNX Look for Alternatives to ME1 Pipe Following Shutdown). Sunoco needs to conduct geotechnical studies near the sinkholes to get answers that will allow it to resume work. So, Sunoco has offered to temporarily relocate five families living near the three sinkholes–for up to six weeks–while it conducts tests of the area…
