Here are a few important dates in the saga of the Dragonpipe (Mariner East 2). I will be updating this with additional dates from time to time.
1930 & 1931: Components of the pipeline that is now called Mariner East 1 (ME1) were built by the Susquehanna Pipe Line Company and the Keystone Pipe Line Company to transport petroleum products to western Pennsylvania from ports on the Delaware River. These changed hands several times over the years, merging into a single pipeline network.
2002: Sunoco acquires ME1 pipeline
2013: Sunoco temporarily retires ME1 pipeline
2014: Sunoco reopens and reverses the direction of flow of ME1 to carry natural gas liquids (NGLs) from western Pennsylvania to Marcus Hook for export to Europe
November, 2016: First shipment of NGLs to Scotland, marking the beginning of full operation of ME1
April 1, 2017: ME1 leaks 20 barrels of NGLs near Morgantown, PA, the third ME1 leak since NGL transport began.
April, 2017: Drilling for Mariner East 2 (ME2) underway at first drill site (Judy Way in Aston, PA)
April 28, 2017: Energy Transfer Partners (ETP) completes its acquisition of Sunoco
May 11, 2017: Drilling fluid surfaces in yards at 5005 & 5007 Chester Creek Road, Brookhaven, PA
May 12, 2017: Drilling fluid in Chester Creek

June 17, 2017: Drilling fluid surfaces in Upper Uwchlan Township, PA
June 23, 2017 (approximate date): Drill at Shoen Road (near Exton, PA) hits aquifer, causing water-quality problems and loss of water in nearby wells.
July 7, 2017: Water problems at Shoen Road become public. Five families moved to hotels.
July 10, 2017: West Goshen files for an “interim emergency order” with the Public Utility Commission regarding Sunoco/ETP’s breach of agreement about site of a valve station. The PUC declines to act.

July 24, 2017: West Goshen wins a stay on construction and drilling on the tract of land under dispute with Sunoco/ETP.
