22-15 Water Supply Plan - Johnston

Traffic & Trucking

22-15 What will happen if an oil operation event occurs more frequently, or lasts longer due to a gas shortage? All the events above indicate that in addition to the figures provided, a 3 truck a day rate is needed just to supply water in addition to the figures above. Do you agree? Please explain.


RESPONSE 22-15

It is difficult to predict the frequency or duration of oil operation events. Invenergy anticipates that they will not be frequent or long in duration. Generally speaking, Invenergy anticipates that it will replenish the tanks shortly following an oil operation event, at the rate specified in the Water Supply Plan. The rate of approximately 22 trucks a day as specified in the Water Supply Plan includes the water trucks needed for continued operation on gas following an oil operation event. The units can run only as long as there is an adequate supply oil and water onsite.  Once the oil and water is depleted, the units cannot run, as set forth in 22-7 and 22-8.
