The oil and gas industry in Pennsylvania has made significant strides in recycling water in recent years. Since 2010, wastewater recycling has increased from 4.6 million barrels to more than 7.8 million barrels per year, according to a 2015 Pennsylvania Department of Environmental Protection, Bureau of Waste Management presentation on water recycling and oil and gas waste.
Given fluctuating market conditions, alternatives to recycling and reuse are also necessary. These alternatives include treatment and disposal both within and outside Pennsylvania. The wastewater disposal options in Pennsylvania have been limited in recent years by a variety of state and federal factors.
DEP asked unconventional operators to voluntarily stop sending wastewater to publicly owned treatment works (POTW) in 2010. EPA finalized a new regulation in 2016 banning unconventional oil and gas operators from sending wastewater to POTWs, a practice the federal Environmental Protection Agency noted as “current” industry practice.
Historically, there have been few injection wells constructed and permitted in Pennsylvania, and some operators have sent wastewater to Ohio and other states where injection wells are more common. Under the Safe Drinking Water Act, EPA issues the federal Underground Injection Control (UIC) permits in Pennsylvania, and then DEP issues a well permit under the Oil and Gas Act to construct a new well or alter an existing well for injection. The Common – wealth has not taken primacy over the federal UIC program. DEP, however, has recently revised its permitting process for the state permit needed to construct and operate UIC wells, revisions made in the midst of legal challenges in both state and federal courts.
EPA identified 15 UIC disposal wells in Pennsylvania, including plugged and abandoned wells and two wells pending permit approval, in its 2016 UIC well inventory. …
