Additional information received. Added by ECCC NEEC DGW "Hi Titaaq, This afternoon we discovered a leak at the flex pipe for Tank #6. It appears to be leaking from the flex pipe itself versus the fittings. That tank is empty. However, it will leak fuel when we are filling the diesel track and the pipes are pressurized. Unfortunately there is no way to isolated this flex pipe from the rest of the diesel supply system. The amount of fuel spilled seems to be small and under the 100 litre threshold for a fuel spill report. We placed a container under the leak and a lot of absorbent pads around the area and anywhere water is running off. We also removed some of the soil under the pipe. Attached are a few pictures. This will need to be repaired as soon as possible. Let me know if you have any questions or concerns.
