oil and gas wastewater

On January 15, 2021, the Texas Commission on Environmental Quality (“TCEQ”) received approval to implement the National Pollutant Discharge Elimination System (“NPDES”) program for oil and gas discharges. [1]  Generally, as a result of this approval, applicants for NPDES permits for produced water, hydrostatic test water, and gas plant effluent will only require a single TCEQ authorization rather than authorizations from both the Railroad Commission of Texas (“RRC”) and the U.S. Environmental Protection Agency (EPA) as previously had been required.

On November 27, 2020, the US Environmental Protection Agency (“EPA”) published notice that the Texas Commission on Environmental Quality (“TCEQ”) has applied to the US EPA for National Pollutant Discharge Elimination System (“NPDES”) program authorization for discharges of produced water, hydrostatic test water and gas plant effluent. [1] TCEQ’s application (“Application”) was filed in response to a bill passed during the last Texas legislative session that required TCEQ to submit to EPA no later than September 1, 2021, a request for NPDES permitting authority for discharges of produced water, hydrostatic test water and gas plant effluent associated with oil and gas activities currently under the jurisdiction of the Railroad Commission of Texas (RRC). [2] Under this legislation, state authority to regulate these discharges will transfer from the RRC to TCEQ upon EPA’s grant of NPDES permitting authority to TCEQ. Should EPA grant NPDES permitting authority to TCEQ for these discharges, a prospective permittee would generally only need to obtain a single TCEQ authorization (rather than an authorization from both the RRC and EPA).
