TGP DISPATCHED OPERATIONS TO THE SITE TO INVESTIGATE. THEY ARRIVED AT 2:10PM AND AT 2:45PM CONFIRMED THAT THE 100-1 LINE WAS LEAKING.

DUE TO WET GROUND CONDITIONS AND LOGISTICS, EXCAVATION OF THE LINE BEGAN ON FEBRUARY 2, 2019. THE LEAK WAS DETERMINED TO BE COMING FROM A CRACK IN THE PIPE GIRTH WELD.
