The Texas Commission on Environmental Quality (TCEQ) continues to clear the path for Brazos Midstream’s growth in the Permian Basin. Most recently, TCEQ completed registration of a Standard Permit for the Cassidy Plant in Glasscock County, Texas (Project #398425, Permit #181608), operated by Brazos Midstream Operating III, LLC.

The September 23, 2025 filing represents a critical compliance milestone under Texas’ air permitting program, ensuring that the Cassidy Plant operates within federal Title V Operating Permit requirements while supporting continued natural gas processing capacity in the Midland region.
This approval comes on the heels of Brazos Midstream’s $185 million Sundance II cryogenic facility expansion in Martin County — a project that doubles the company’s Midland Basin processing capacity to 500 MMcf/d. Together, these regulatory approvals demonstrate how midstream operators are navigating environmental compliance while investing heavily in critical infrastructure.
Why the Air Permits Matter
Air permits are more than regulatory paperwork — they are the foundation for operating responsibly and expanding capacity in Texas.
- Standard Permit for Cassidy Plant – By registering under TCEQ’s standardized program, Brazos ensures ongoing compliance for its Glasscock County operations, allowing the facility to continue gathering and processing gas without disruption.
- Sundance II Expansion – The air permit supporting this cryogenic facility highlights Brazos’ commitment to scaling capacity while adhering to low-emission permitting pathways.
Together, these steps reinforce that Brazos Midstream is not only growing its footprint but doing so in alignment with environmental standards.
Texas’ JETI Program: Supporting Energy Infrastructure
The Jobs, Energy, Technology, and Innovation (JETI) program, launched by the State of Texas, is designed to attract and accelerate private investment in critical energy infrastructure. By providing financial and regulatory support, JETI encourages projects that enhance reliability, expand capacity, and drive innovation across the energy sector.
Brazos Midstream’s Sundance II facility is a prime example of this program in action. Backed by JETI, the project reflects Texas’ proactive approach to ensuring that its infrastructure can keep pace with rising natural gas production and growing energy demand. Beyond midstream capacity, JETI projects deliver:
- Local Jobs – Construction and long-term operations create new employment opportunities in counties like Martin and Glasscock.
- Statewide Energy Security – New facilities reinforce Texas’ position as the cornerstone of U.S. energy supply.
- Innovation Incentives – By tying investment to environmental and technological improvements, the program drives forward-thinking infrastructure development.
Brazos Midstream’s Role in the Permian
Brazos Midstream has established itself as a mission-critical partner for producers across the Midland Basin. By expanding processing capacity and maintaining strict regulatory compliance, Brazos delivers three core benefits:
- Energy Security – Additional gas processing ensures that Texas continues to serve as a cornerstone of U.S. energy supply, supporting both domestic and global markets.
- Infrastructure Resilience – The added capacity helps reduce flaring and prevents bottlenecks in one of the fastest-growing gas-producing regions.
- Local Impact – Projects like Sundance II and Cassidy Plant operations generate construction and long-term jobs in Martin and Glasscock counties.
The Permian Basin Context
The Midland Basin, part of the broader Permian, accounts for nearly 25% of Lower 48 natural gas production. With drilling activity expanding and associated gas volumes climbing, midstream operators must keep pace.
Brazos Midstream’s Cassidy Plant permit and Sundance II expansion together demonstrate a strategy of compliance and growth — ensuring producers can move gas efficiently to market, while minimizing environmental impact.
Conclusion
By securing key TCEQ air permits across its facilities and leveraging support from the Texas JETI program, Brazos Midstream is strengthening its position as a vital link in the Permian’s natural gas value chain. These approvals underscore the dual mandate of today’s midstream operators: enable production growth while upholding environmental responsibility.
As natural gas demand continues to rise, both in the U.S. and abroad, Brazos Midstream’s blend of compliance, investment, and innovation ensures the Permian remains the backbone of American energy.
