On October 8, 2016, the Pennsylvania Environmental Quality Board published a comprehensive set of new rules regulating hydraulic fracturing operations in the state. Discussion of these rules began in 2011 and resulted in significant opposition--including resistance at the Pennsylvania legislature. Pennsylvania’s rules governing above-ground operations at oil and gas well sites had not been updated since 2001, prior to the expansion of hydraulic fracturing in the state. Under the regime implemented by the new rules, Pennsylvania has bifurcated its regulation of conventional and unconventional wells; the regulations governing conventional operations appear at 25 Pa. Code Chapter 78, while the regulations governing unconventional operations appear at 25 Pa. Code Chapter 78a. Many fear that the new rules will stifle energy production at a time when production has already slowed due to uncertain commodity prices, while others argue that the rules provide changes to protect both public health and the state’s natural resources.
