CANONSBURG, PA. – Citing the extraordinary potential of responsibly developing natural gas from the Marcellus Shale, Range Resources Corporation yesterday announced a voluntary disclosure initiative of Marcellus Shale hydraulic fracturing additives.

Beginning immediately, Range will voluntarily submit to the Pennsylvania Department of Environmental Protection (DEP) additional information about additives used in the process of hydraulic fracturing of natural gas wells in Pennsylvania operated by Range Resources.

Range’s disclosure initiative will provide regulators, landowners and citizens of the Commonwealth an accounting of the highly diluted additives used at each well site, along with their classifications, volumes, dilution factors, and specific and common purposes. The information will be submitted to the DEP as part of Range’s well completion reports and on the company’s website.
