Rob,
I wrote you on April 30th about my thoughts regarding the new monitoring well that the Division wants EFCI to
drill to replace the MWNW. Since I haven't heard any reply to that email, and since the plans for a new well
seem to be progressing in spite of my concerns, I would like to again say that I do not think the small
possible amount of information to be gained from a new well is worth the large potential risks of such drilling.
There are two potential risks of fires. The first one is from the underground fire that Harrison Western and GEC
caused on our property at the directive of the Division to transport burning waste from the Shamrock Mine to be
deposited in the GEC strip pits. The present extent and location of this fire is completely unknown today, and it
may be far too close to the new monitoring well location for safety. The second risk is the possibility of starting
a new underground fire in the drilling process. The Southfield Mine probably contains an explosive atmosphere
from methane, and there will be no chance to monitor the methane concentration in the drilling process. Despite
using an inert gas mixture in the well bore during the drilling, when the drill string penetrates the mine void the
amount of carbon dioxide or nitrogen in the well bore will be insignificant in comparison to the amount of gas in
the mine void. A single spark, an explosion, and an underground coal fire could be the result. Since the well
location will be 47.69 feet from our property I think we have a valid objection to this new monitoring
well. Because the Division had the jurisdiction over the events that caused the Harrison Western/GEC
underground fire thirty-five years ago, I am asking that my concerns receive special consideration this time.
Please do not demand that EFCI drill another well; I doubt that the Division wants to be in the position of
assuring us that there is zero chance of an underground coal fire.
