EPA Subpoenas Halliburton Over Fracking Fluids

The Environmental Protection Agency said on Tuesday it has issued a subpoena to Halliburton for not revealing information about liquids used in a natural gas drilling technique called "fracking."

In September, the EPA had asked nine companies that practice hydraulic fracturing, or fracking, to reveal the mix of chemicals they use in the practice which is opposed by environmental groups worried about its effect on drinking water.

All but Halliburton provided the necessary information, the EPA said. Shale gas stirs energy hopes, environment concerns

The EPA says it needs the data on fluids used in fracking to complete its comprehensive study of the technique. During fracking, companies inject millions of gallons of water, sand and chemicals as far as two miles underground to break open fissures in the gas-bearing shale.

The EPA is slated to release preliminary results of the study, commissioned by Congress, by the end of 2012.

Fracking has been around for decades, but companies have expanded its use in recent years to extract abundant but hard-to-access reserves of shale gas.

Homeowners near some shale field developments say fracking has made their tap water toxic, and that in some cases flammable gases have escaped through their spigots.

"UNREASONABLE DEMANDS"

Halliburton said it has been working with the EPA on its request and had provided some 5,000 pages of documents as of last week. The company said it was meeting with the EPA "in order to help narrow the focus of their unreasonable demands" that could require them to prepare about 50,000 spreadsheets.

An EPA official said Halliburton had submitted publicly available forms that describe the general hazards associated with various chemical mixes.

"While these are helpful, they do not identify each and every chemical in a mixture, which is precisely the sort of information EPA needs to understand the risks these ... mixtures may pose to drinking water supplies," the official said.

The EPA had also asked all of the companies for standard operating procedures that govern the choice and amount of chemicals and water used in fracking jobs, along with locations of every fracking job undertaken in the previous year or planned for the next. Halliburton has not given that information.

The companies that had provided EPA with the information are Schlumberger, BJ Services, Complete Production Services, Key Energy Services, Patterson-UTI, RPC Inc, Superior Well Services and Weatherford.
