EPA to shed light on fracturing rules

Diesel injections will be focus of clarification on natural gas work

The guidance, which EPA Administrator Lisa Jackson says is coming "very shortly," is meant to clear up rules for natural gas producers.
A congressional investigation concluded earlier this year that companies have not secured EPA permits before injecting more than 32 million gallons of diesel fuel and other fluids into the ground in fracturing operations between 2005 and 2009.
States historically have regulated hydraulic fracturing. The technique involves injecting mixtures of water, sand and chemicals including diesel fuel deep underground at high pressures to break up dense shale rock and release gas locked in it. Although Congress exempted most hydraulic fracturing activities from EPA's jurisdiction as part of a 2005 rewrite of the Safe Drinking Water Act, that exception does not apply to diesel - even though the government only began to regulate it last year.
Jackson insisted that the EPA has authority to regulate diesel fuel in fracturing fluids.
