Eagle Ford Shale Geological Area
The TCEQ’s primary role in the oil and gas fields is regulating emissions and ensuring air quality. Working with the Railroad Commission, which has primary jurisdiction over oil and gas facilities in Texas, the TCEQ is devoting significant resources to make sure those responsibilities are met. Based on lessons learned from the TCEQ’s work in the Barnett Shale area, numerous activities have already been conducted or will soon take place to help the agency remain in front of any environmental issues in the Eagle Ford Shale area.
The TCEQ continues to use innovative approaches to find ‘real world solutions’ that actually reduce emissions. The TCEQ has undertaken numerous projects that use state-of-the-science technology to assess and address emissions from oil and gas activities. These initiatives have resulted in emissions reductions through improved agency policies, guidance for regulated entities and possible enforcement if necessary.
