Gas Execs Call for Disclosure of Chemicals Used in Hydraulic Fracturing

Two prominent gas industry executives have directly addressed one of the key environmental concerns surrounding the expansion of natural gas development by calling for the disclosure of chemicals used in hydraulic fracturing.
The statements - made last week by Chesapeake Energy CEO Aubrey McClendon and Range Resources CEO John Pinkerton - came as the industry faces increasing pressure to be more forthcoming about the chemicals it uses. New York state recently released an environmental impact statement that specifically called for disclosure of the chemicals used in hydraulic fracturing. Colorado and several other states also have asked for that information.
At issue is whether hydraulic fracturing, and the chemicals it requires, might be responsible for water contamination incidents in drilling areas across the country. The process, which is currently exempt from federal oversight under the Safe Drinking Water Act, forces millions of gallons of water, mixed with sand and small amounts of chemicals, into the earth to break rock and release gas. Scientists, including some at the Environmental Protection Agency, have said they can't thoroughly investigate the contamination incidents because the names of the chemicals are protected trade secrets.
At a panel discussion at the IHS Herold Pacesetters Energy Conference in Greenwich, Conn., McClendon told attendees that fracturing should be demystified, and that "we need to disclose the chemicals that we are using and search for alternatives," according to an account of the discussion from Reuters. In other news reports, McClendon was quoted as saying he was concerned that undue fears about the drilling chemicals had bogged down efforts to open the Marcellus Shale, a mammoth natural gas deposit that lies beneath much of Ohio, West Virginia, Pennsylvania and New York.
Chesapeake and other gas producers subcontract fracturing services from companies that specialize in the process, including Halliburton, Schlumberger and BJ Services. In the past, those companies have said they are differentiated by the recipes they use for fracturing underground and that forced disclosure would erase any competitive advantage. But a Schlumberger spokesperson was recently quoted as saying the company is willing to discuss more disclosure.
At the energy conference, Pinkerton called the companies' concerns that disclosure would put them at a disadvantage "silly" and said, according to a report in Natural Gas Intelligence, that "I've basically told them that this is not acceptable."
Chesapeake and several gas industry associations already offer the public educational fact sheets that detail a few dominant ingredients in fracturing solutions, but the fact sheets don't list all the ingredients or explain how they might be combined, information that environmental scientists say is critical to measuring the risk associated with fracturing fluids. It isn't clear how much more McClendon and Pinkerton would favor disclosing.
"The question remains, what is that disclosure going to be?" said Amy Mall, a policy analyst for the Natural Resources Defense Council. "Is it going to be specifics that allow a health specialist or a hydrologist to analyze exactly what the risks are to human health? The devil is in the details."
A Chesapeake spokesman declined to clarify McClendon's statements, but in an e-mailed response said "the discussion about the types of additives used in minimal amounts during hydraulic fracturing is misguided since each additive that is brought onto a well location is accompanied by a Materials Safety Data Sheet, which not only identifies the materials but outlines proper ways in which to utilize them." The MSDS sheets, which are available to the public, are required by law to provide information on how workers might be poisoned by chemicals - but they've also been criticized as providing only partial information.
