Railroad Commission of Texas
The Railroad Commission of Texas (RRC; also sometimes called the Texas Railroad Commission, TRC) is the state agency that regulates the oil and gas industry, gas utilities, pipeline safety, safety in the liquefied petroleum gas industry, and surface coal and uranium mining. Despite its name, it ceased regulating railroads in 2005, when the last of the rail functions were transferred to the Texas Department of Transportation.
