My column of April 4 on fracking generated a response from Steve Everley of Energy in Depth, a Washington, D.C. oil and gas industry-backed interest group.
In his letter, Everley takes issue with the report from the N.C. Department of Environment and Natural Resources that said there’s little data on how hydraulic fracturing affects drinking water supplies.
Everley states: “In 1995 and again in 2004, the U.S. EPA concluded that hydraulic fracturing does not pose a risk to drinking water.”
That is clearly not true.
The 1995 event to which Mr. Everley appears to refer was testimony given by EPA Administrator Carol Browner in a suit over how fracking should be regulated. She testified that there was "no evidence that hydraulic fracturing resulted in any drinking water contamination.”
That is far different than claiming that fracking does not pose a risk. It simply means that at that point in 1995 – 17 years ago – no evidence had been found.
The 2004 study Mr. Everley refers to has been criticized by one of its own authors, a former Bush administration EPA official.
The 2004 study was one in which EPA looked at whether fracking in coalbeds was causing contamination of water supplies. I’ll leave aside the question of how applicable any studies of coal-producing regions may translate to the geology of North Carolina and just point out this: Benjamin Grumbles, one of the EPA officials who supervised production of the study, said:
"EPA, however never intended for the report to be interpreted as a perpetual clean bill of health for fracking or to justify a broad statutory exemption from any future regulation under the Safe Drinking Water Act.”
Additionally, an EPA whistleblower charged that the conclusions of the 2004 study were unsupported and that some members of the study’s peer review panel had conflicts of interest.
The EPA now is conducting a large-scale study examining whether fracking contaminates water supplies. We would be wise to put a hold on the movement to allow fracking in North Carolina until we have clear evidence that it can be done safely.
Our water is more important than natural gas.
