Seems they could fix it by inviting media and concerned members of the public to tour the site; and cancel the use of its own subsidiary to provide the water sampling and hire a third-party contractor to help assure the public its not getting hoodwinked.

An important aspect to this story was I proposed a possible leak source for the 4 inch line based on cold weather pipe contraction. Keylor then proceeded to tell that on Jan. 3, they had to fix a leaking pressure gauge by removing it and plugging the tap. He went on to relate they estimated loss at less than 25 gallons. I made the point that such a leak could lose far more than 25 gallons and especially over a long period of time and that was a “game over” situation. The next day I did a flow calculation that showed a 1/8 inch sch.80 pipe tap for a gauge (min. size) could leak 19 to 25 gallons PER MINUTE. They would have had to been there when the gauge broke, turned off pressure in line and plugged it less than a minute’s time to only leak 25 gallons. In 4.5 hours it could have leaked all the 6000 gallons of “hydrocarbons” they have recovered. If they were filling tank(s) in the tank farm across the river, and using automated systems to turn off valves and transfer fills on tanks. They could have easily gone 24 hours before a initiating shift returned to discover the delayed fill and sent a crew out to inspect. In this time, up to 32,000 gallons (762 bbl.s) could have spilled. A “just for instance” of underestimating the seriousness of something initially being determined “minor”. However, the fact that Keylor brought this up indicates to me that they realized at some point this was, in fact, a serious happening.
