EPA Report Recognizes Railroad Commission’s Underground Injection Control Program
Mitigating Environmental RisksJuly 29, 2020
AUSTIN – The Railroad Commission continues to make positive strides with its Underground Injection Control program, ensuring the protection of underground sources of drinking water and the control of seismic activity, according to a recent report from the Environmental Protection Agency.
RRC’s UIC program protects the state’s drinking water and controls seismic activity through enforcement of EPA-approved rules on permitting, construction, and testing of underground injection wells. Injection wells are used to process waste fluid from oil and gas operations, especially water with high levels of brine; for brine mining; for enhanced recovery, which prolongs the life of oil and gas fields; and hydrocarbon storage. Wells are located in underground formations geologically separate from aquifers that are sources of drinking water.
“The Railroad Commission continues to confront significant challenges in the program and has taken some innovative measures to address them,” the summary of EPA’s report reads.
“The EPA’s report acknowledges the efforts of Railroad Commission staff to responsibly manage injection wells to protect our natural resources and mitigate any seismic activity because of them,” said Paul Dubois, RRC Assistant Director for Technical Permitting. “We will continue to work with our federal counterparts to build on and improve our work to help protect Texans.”
Among the report’s key findings include:
- More than half of all injection wells in the state are inspected annually. The EPA report notes that “Those numbers assure more than adequate inspection and monitoring surveillance actions.”
- The report also noted that RRC rules enacted in November 2014, a guidance document adopted in 2019, and increased UIC staffing “enhance RRC authority regarding seismicity related to Class II disposal … and establish new permit application information to address seismic risk in problematic areas of the State.”
- A recognition of RRC’s critical review of disposal well applications, which resulted in 65 permits issued with special conditions, 19 withdrawn or returned applications, hearings scheduled for 56, and three permits issued without any special conditions. Also, the agency evaluated the role of two disposal wells in an earthquake near Timpson in September 2018, which resulted in the modification of one permit to reduce pressure and the canceling of the other permit.
