On May 4, the U.S. Environmental Protection Agency issued a draft underground injection control permitting guidance for oil and gas hydraulic fracturing activities using diesel fuels.
Now the agency has extended the public-comment period on that proposal by 45 days to Aug. 23.
The Energy Policy Act of 2005 exempted hydraulic fracturing operations from requirements to obtain an underground injection control (“UIC”) permit under the federal Safe Drinking Water Act ("SDWA"), except when diesel fuels are used as a fracturing fluid. However, the act did not define the term “diesel fuels.”
The proposed guidance attempts to provide clarity for EPA permit writers issuing UIC permits under the SDWA.
Environmental groups have lobbied for EPA to broadly define the term “diesel fuels” to include any material containing benzene, toluene, ethylbenzene, and xylene compounds.
Industry has advocated for a narrower, more traditional definition of diesel fuels.

The proposed guidance will be subject to public notice and comment.
