How to Search for T-4 Permits

Pipeline operators in Texas are required by 16 TAC §3.70 to have a valid permit to legally operate their lines if they leave any tract of land that the operator controls. (This control can either be by ownership or by lease agreement.) Permits are acquired by submitting a Form T-4, a valid map and a brief cover letter explaining what is taking place. The permit issued to the operator is also called a T-4A. Permits must be amended whenever changes take place. The change can be done with a Form T-4 and maps. If no changes are made, the permits need to be renewed annually with a form T-4C. There are currently roughly 8600 permits with about half being active. Online Permit files are updated approximately once each month.
