EPA announces schedule to develop hydrofracking wastewater standards

Posted by Neno Duplan

The U.S. Environmental Protection Agency (EPA) is announcing a schedule to develop standards for wastewater discharges produced by natural gas extraction from underground coalbed and shale formations. No comprehensive set of national standards exists at this time for the disposal of wastewater discharged from natural gas extraction activities, and over the coming months EPA will begin the process of developing a proposed standard with the input of stakeholders – including industry and public health groups. Today’s announcement is in line with the priorities identified in the president’s Blueprint for a Secure Energy Future, and is consistent with the Secretary of Energy Advisory Board recommendations on steps to support the safe development of natural gas resources.

Currently, wastewater associated with shale gas extraction is prohibited from being directly discharged to waterways and other waters of the U.S. While some of the wastewater from shale gas extraction is reused or re-injected, a significant amount still requires disposal. As a result, some shale gas wastewater is transported to treatment plants, many of which are not properly equipped to treat this type of wastewater. EPA will consider standards based on demonstrated, economically achievable technologies, for shale gas wastewater that must be met before going to a treatment facility.
