What we do
The Oversight and Safety Division has responsibility for Alternative Fuels, Gas Services and Pipeline Safety. This reorganization in January 2015 will bring even greater efficiency and consistency to these operations within the Commission, allowing the agency to better serve the state.
The Railroad Commission of Texas (Commission) is the state agency responsible for regulating the safe storage, transportation and use of Liquefied Petroleum Gas (LPG, Propane, Butane), Compressed Natural Gas (CNG), and Liquefied Natural Gas (LNG), pursuant to the Texas Natural Resources Code (TNRC). The Commission has also adopted regulations for each fuel type under the Texas Administrative Code, Title 16, Chapters 9, 13, and 14, respectively.
The Alternative Fuels Safety (AFS) department enforces both the state statutes and the Commission’s regulations on these fuels, by conducting safety evaluations of stationary facilities and mobile equipment, licensing companies engaged in alternative fuel activities, and providing training to individuals working in the alternative fuels industries.
