EPA Seeks More Information from Natural Gas Drilling Operations to Ensure Safety of Wastewater Disposal
Jun 07, 2011
The U.S. Environmental Protection Agency today directed six natural gas drillers to disclose how and where the companies dispose of or recycle drilling process water in the region.
- Notify EPA when facilities are accepting hydraulic fracturing wastewater so EPA can assess if a pretreatment program or additional permit limits are needed;
- Apply water quality standards for the protection of drinking water at the point of wastewater discharge, rather than at the point of first downstream drinking water intake;
- Consider more “representative” sampling where drinking water facilities are downstream of treatment plants accepting Marcellus Shale gas wastewater; and
- Be aware that EPA has sent a letter to PADEP’s southwest regional office clarifying that Federal Underground Injection Control permits are required for any placement of hydraulic fracturing wastes in injection wells or bore holes.
