Pre-submittal readiness scoring for UIC injection well permits

Class VI · Texas

Built against 16 TAC §§5.201–5.207

Texas Class VI primacy effective December 15, 2025

The Railroad Commission of Texas (RRC) is now the primary permitting authority for Class VI wells in Texas. This tool scores readiness against RRC's published rules. Projects on Indian lands remain under EPA authority and are out of scope for this tool.

Appears on the cover of your readiness report. Use any internal project label (e.g., “Permian-NW Block 12”). Must be at least 4 characters and a real Project Name (placeholder names like “test” are rejected). Do not include confidential information.

Step 1 of 8

Project Jurisdiction & Classification

Confirms the project belongs in the Texas Class VI permitting pathway and identifies any gating authority issues.

Question 1 of 6Showstopper

Is the proposed injection activity located in Texas and intended for long-term geologic sequestration of CO2 (not enhanced recovery, short-term experimental injection, or other purpose)?

16 TAC §5.201·Class VI Applicability — Texas / Geologic Storage Purpose

Texas RRC primacy applies only to Class VI wells in Texas (effective December 15, 2025). Enhanced recovery or short-term experimental injection follows a different pathway.

Question 2 of 6

Has the applicant documented why the project is Class VI rather than Class II — including injection pressure, mass/volume, reservoir purpose, and USDW protection considerations?

16 TAC §5.201·Class VI vs. Class II Documentation

RRC distinguishes Class II from Class VI substantially by pressure and volume thresholds plus geologic storage intent. Documentation is essential to avoid mid-application reclassification.

Question 3 of 6Showstopper

Is any portion of the injection well, storage facility, plume, pressure front, or AOR located on Indian lands?

16 TAC §5.203(b)(2)(E)·Indian Lands Disclosure

EPA Region 6 retains permitting authority for Class VI wells on Indian lands within Texas — this tool does not score those projects.

Question 4 of 6

Has the applicant identified all counties, municipalities, state boundaries, tribal contacts, and territories that fall within or near the modeled AOR?

16 TAC §5.203(b)(2)(F)·AOR State / Tribal / Territorial Contacts

Required as part of the surface map and AOR documentation. Contact list must be updated after final AOR modeling.

Question 5 of 6

Does the project involve conversion, recompletion, or use of an existing oil and gas, Class II, Class I, Class V, stratigraphic, or monitoring well?

16 TAC §5.201·New Well or Existing Well Conversion

Existing well conversions require stronger construction history and integrity evidence — adequacy of as-built records, MIT history, and casing condition is critical.

Question 6 of 6

Has the applicant identified every permit, approval, or environmental program interface required for the facility — including RRC, TCEQ, EPA Region 6, and any local requirements?

16 TAC §5.203(a)(2)(C)·Required Permits & Agency Interfaces

Required under §5.203(a)(2)(C). Missing interface permits often surface as schedule risk during technical review.
