Chesapeake is drilling all over the Fayetteville Shale in Arkansas also. Several agencies noted sediment pollution from its installation of pipelines into streams at a conference I attended last fall. So far, I do not think ADEQ has done anything about it. The state agencies are hamstrung because of politics.
We now also have a company wanting to drill several wells of 2,000 feet and pump up to 850,000 gallons of water a day from them in the Calico Rock area to produce fracking sands. The water will be pumped into a large quarry on 2,000 acres, and they have a permit to discharge into the local streams if necessary.
One thing that will help agencies monitor this in the future is real time satallite imagery.
I recommend if anyone finds sediment discharges or road cuts causing sediment run-off in your area you contact the feds–EPA or USFWS. You might get more help from them than the local boys.
