Guidance for Supplemental Information on Class VI Projects by TCEQ

In addition to the information requested in the Class VI permit application, supplemental information is required for the Texas Commission on Environmental Quality (TCEQ) Underground Injection Control (UIC) Permits Section staff to make a determination that drilling and operating an anthropogenic CO2 injection well for geologic storage or constructing or operating a geologic storage facility will not impact or interfere with any previous or existing Class I injection well, including any associated waste plume, or any other injection well authorized or permitted by the commission. This information provides additional key criteria necessary for reviewing Class VI applications, with a focus on modeling and simulation assessments.
