I. Introduction

A. Federal UIC Program and Primary Enforcement Authority (Primacy)

    The Safe Drinking Water Act (SDWA), passed in 1974, protects public 
health by regulating the nation's public drinking water supply, 
including both surface and groundwater sources. Among other things, the 
SDWA requires the EPA to develop minimum requirements for effective 
State and Tribal UIC programs to prevent underground injection of 
fluids (such as water, wastewater, brines from oil and gas production, 
and carbon dioxide) from endangering underground sources of drinking 
water (USDWs). In general, USDWs are aquifers or parts of aquifers that 
supply a public water system or contain enough groundwater of 
sufficient quality to supply a public water system. See 40 CFR 144.3 
(defining USDW).
    The EPA's UIC program regulates various aspects of injection. These 
include technical aspects throughout the lifetime of the project from 
site characterization, construction, operation, and testing and 
monitoring through site closure, as well as permitting, site 
inspections, and reporting to ensure well owners and operators comply 
with UIC permits and regulations.
    SDWA section 1421 directs the EPA to establish requirements that 
States, territories, and authorized Tribes must meet to be granted 
primary enforcement responsibility, or ``primacy,'' for a UIC program. 
42 U.S.C. 300h. SDWA section 1422 provides that an applicant seeking 
primacy for a UIC program must demonstrate to the EPA that the 
applicant's proposed UIC program meets the applicable requirements 
promulgated by the EPA pursuant to section 1421 for protecting USDWs. 
42 U.S.C. 300h through 300h-1. An applicant must demonstrate, among 
other things, jurisdiction over underground injection and that the 
applicant possesses the administrative, civil, and criminal enforcement 
authorities required by the EPA's implementing regulations. See 40 CFR 
part 145, subpart B. After the EPA approves a State for UIC program 
primacy, the State's UIC program may be revised with EPA approval. See 
40 CFR 145.32.
    The EPA evaluates each primacy application in accordance with SDWA 
section 1422 and the EPA's implementing regulations to determine 
whether the applicant (in this instance, the State of Texas) has 
satisfactorily demonstrated that, after reasonable notice and public 
hearings, it has adopted and will implement a UIC program that meets 
the requirements of the SDWA regulations at 40 CFR parts 144, 145, and 
146. The EPA conducts a similar comprehensive evaluation for proposed 
State UIC program revisions, including a program revision to add Class 
VI primacy where an applicant already has primacy to implement other 
classes under the UIC program.
    In this final rule, the EPA is approving Texas's program revision 
application to administer the UIC Class VI program in the State. EPA's 
approval is based on the Agency's determination that the application 
meets all applicable requirements for approval under SDWA section 1422 
and the EPA's implementing regulations and that the State is capable of 
administering a UIC program in a manner consistent with the SDWA and 
applicable UIC regulations. The EPA will remain the permitting 
authority for all Class VI wells on Indian land within the State and 
will oversee Texas' administration of the State's UIC Class VI program 
pursuant to the SDWA.

B. Class VI Wells Under the UIC Program

    Class VI wells are used to inject carbon dioxide into deep rock 
formations for the purpose of long-term underground storage, also known 
as geologic sequestration. The geologic sequestration of carbon dioxide 
in UIC Class VI wells is used as part of carbon capture and storage for 
carbon dioxide emissions from industrial sources. Class VI injection 
wells are regulated under a SDWA permitting framework that protects 
USDWs.
    The UIC Class VI program provides multiple safeguards that work 
together to protect USDWs. Permit applicants that want to inject carbon 
dioxide underground for the purpose of geologic sequestration must 
obtain a Class VI permit for each well by demonstrating to the UIC 
permitting authority that their proposed injection well and injection 
activities will meet all regulatory requirements, including the 
following technical, financial, and managerial requirements:
     Site characterization to ensure the geology in the project 
area will contain the carbon dioxide within the zone where it is 
authorized to be injected.
     Modeling to delineate the predicted area influenced by 
injection activities through the lifetime of the project.
     Evaluation of the delineated area to ensure all potential 
pathways for fluid movement have been identified and addressed through 
corrective action.
     Well construction requirements that ensure the Class VI 
injection well will not leak carbon dioxide.
     Testing and monitoring throughout the life of the project, 
including after carbon dioxide injection has ended. Requirements 
include, for example, testing to ensure physical integrity of the well, 
monitoring of injection pressure and flow, chemical analysis of the 
carbon dioxide stream that is being injected, monitoring the extent of 
the injected carbon dioxide plume and the surrounding area (e.g., 
ground water) to ensure the carbon dioxide is contained as predicted, 
and may also include monitoring for seismic activity near the injection 
site.
     Operating requirements (for example, injection pressure 
limitations) to ensure the injection activity will not endanger USDWs.
     Financial assurance mechanisms sufficient to cover the 
costs for all phases of the geologic sequestration project including 
the post-injection site care period and until site closure has been 
approved by the permitting authority.
     Emergency and remedial response plans to protect USDWs.
     Reporting of testing and monitoring results to the 
permitting authority to ensure the well is operating in compliance with 
all permit requirements.
    The permitting authority ensures that these protective requirements 
are included in each Class VI permit. A draft of each Class VI permit 
is made available to the public for comment before the decision is made 
whether to issue a final permit.

II. Legal Authorities

    The statutory authority for this final rule is SDWA sections 1422 
and 1450, 42 U.S.C. 300h-1 and 300j-9.
    SDWA section 1421 requires the EPA to promulgate requirements for 
effective State UIC programs to prevent underground injection 
activities that endanger USDWs. 42 U.S.C. 300h. SDWA section 1422 
requires that applicants seeking primacy approval demonstrate that they 
have adopted (after notice and public hearing) and will implement a UIC 
program which meets the requirements that the EPA promulgated under 
SDWA section 1421. 42 U.S.C. 300h-1.
    The EPA has promulgated regulations setting forth the applicable 
procedures and substantive requirements for applicants seeking primacy 
approval for UIC programs under SDWA section 1422. The regulations in 
40 CFR part 144 outline general program requirements that States must 
meet to

[[Page 51023]]

obtain primacy. The regulations in 40 CFR part 145 specify the 
procedures the EPA will follow in approving, revising, and withdrawing 
UIC programs and outlines the elements and provisions that an applicant 
must include in its application for primacy. 40 CFR part 145 also 
includes requirements for State UIC permitting programs (by reference 
to certain provisions of 40 CFR parts 124 and 144), compliance 
evaluation programs, enforcement authority, and the sharing of 
information between the EPA and the State. The regulations in 40 CFR 
part 146 contain the technical criteria and standards applicable to 
each well class, including Class VI wells.

III. Texas' Application for UIC Class VI Primacy

A. Background

    On February 20, 2025, Texas submitted to the EPA a program revision 
application to add Class VI wells to the State's existing SDWA section 
1422 UIC program. Once approved by EPA, Texas' requirements for UIC 
wells would be codified and implemented in lieu of the Federal UIC 
requirements currently in effect in the State. See 40 CFR part 147, 
subpart SS. The UIC program revision application from Texas includes a 
description of the State's proposed UIC Class VI program, copies of all 
applicable rules and forms, a statement of legal authority, a summary 
of Texas' public participation activities, a letter from the Governor 
of Texas requesting program approval and an addendum to an existing UIC 
Memorandum of Agreement (MOA) between Texas and the EPA Region 6 
Administrator. The EPA reviewed the application for completeness and 
performed a technical and legal evaluation of the application materials 
to assess and confirm that Texas' proposed UIC Class VI program meets 
Federal requirements.

B. Public Participation Activities Conducted by Texas

    The RRC proposed regulations for the geologic storage of carbon 
dioxide (CO2) in a notice and request for comment published 
on its website on September 29, 2010, and in the Texas Register on 
October 15, 2010. On December 17, 2010, the RRC responded to comments 
and adopted final regulations (16 Tex. Admin. Code secs. 5.101-5.308). 
On March 20, 2012, the RRC proposed amendments to its CO2 
geologic storage regulations. The RRC provided notice of these proposed 
amendments through the Texas Register on April 6, 2012, and held a 31-
day comment period closing on May 7, 2012. The RRC issued a response to 
comments and notice of the adoption of the final amendments to the 
regulations in the Texas Register on June 29, 2012.
    The RRC proposed additional amendments to its CO2 
geologic storage regulations in 2022 as part of its effort to develop 
and submit a program revision application to receive primacy for the 
Class VI UIC program. The RRC published notice of the proposed 
amendments and a 31-day opportunity for public comment in the Texas 
Register on May 20, 2022. The RRC held a public hearing on the proposed 
regulatory amendments via webcast on June 14, 2022. The RRC received 18 
comments on the proposed amendments, five from industry associations 
(the Greater Houston Partnership, NARO-Texas, the Permian Basin 
Petroleum Association, the Texas Industry Project, and the Texas Oil 
and Gas Association), ten from companies or organizations, two from 
individuals, and one comment submitted on behalf of 37 Texas-based 
organizations and individuals. Comments on the regulations covered 
technical, administrative, and procedural requirements, some of which 
resulted in changes to the proposed amendments. Most commenters 
expressed support for Texas' planned program revision application 
requesting primacy for the Class VI program. However, one commenter 
requested Texas withdraw its anticipated application based on the 
commenter's criticisms of the RRC's oversight and enforcement of the 
programs it currently implements. The RRC issued a response to comments 
and notice of the adoption of the amendments in the Texas Register on 
September 16, 2022.
    In response to feedback from the EPA, the RRC proposed additional 
amendments to its CO2 geologic storage regulations in 2023. 
The RRC provided notice of the proposed amendments and an opportunity 
for public comment through July 31, 2023, on the RRC website on June 
15, 2023, and in the Texas Register on June 30, 2023. The RRC received 
30 comments on the proposed amendments, six from industry associations 
(Greater Houston Partnership, Reliable Energy Alliance, Texas Chapter 
of National Association of Royalty Owners, Texas Chemical Council, 
Texas Industry Project, and the Texas Oil and Gas Association), two 
from organizations (Environmental Defense Fund and Commission Shift), 
21 from individuals and one on behalf of 31 Texas-based organizations 
and individuals. Some of the comments expressed support for Texas' 
program revision application requesting primacy for the Class VI 
program. Other comments expressed concern about the process and 
potential environmental and public health impacts from the injection 
and geologic storage of CO2. Some commentors requested Texas 
withdraw its application for Class VI primacy. In addition, the RRC 
received comments on the proposed amendments to the State regulations 
regarding the technical, administrative, and procedural requirements, 
some of which resulted in changes to the proposed amendments. The RRC 
issued a response to comments and notice of the adoption of the 
amendments to the regulations in the Texas Register on September 8, 
2023.
    Documentation of Texas' public participation activities, including 
comments received and responses by the RRC, can be found in the EPA's 
Docket ID No. EPA-HQ-OW-2025-0157.

C. Summary of the EPA's Comprehensive Evaluation

    The EPA evaluates applications from primacy authorities to revise 
their UIC programs in accordance with SDWA section 1422 and 40 CFR 
145.32 to determine whether an applicant has satisfactorily 
demonstrated that its proposed program revision meets EPA regulatory 
requirements and the SDWA. The EPA conducted a comprehensive technical 
and legal evaluation of Texas' program revision application to 
determine whether the State's proposed UIC Class VI program--including 
statutes and regulations, program description, Attorney General's 
statement, and MOA addendum--meets the requirements of SDWA section 
1422 and EPA regulations. Upon review, the EPA determined that Texas' 
program revision application demonstrates that the State has adopted 
and will implement a Class VI UIC program that meets the requirements 
of 40 CFR parts 144, 145, and 146.
    The EPA evaluated Texas' UIC Class VI program description for 
consistency with 40 CFR 145.23, which specifies all the information 
that must be included as part of the program description. The EPA's 
evaluation of the UIC Class VI program description included reviewing 
the scope, coverage, processes, and organizational structure of the 
proposed Class VI program. The EPA evaluated Texas' permitting, 
administrative, and judicial review procedures relevant to Class VI 
permits, as well as the State's permit application, reporting, and 
manifest forms for Class VI permits. The EPA also reviewed the State's 
UIC compliance evaluation program and enforcement authorities and the 
State's demonstration that its UIC Class VI

[[Page 51024]]

program will have adequate in-house staff or access to contractor 
support for technical areas including site characterization, modeling, 
well construction and testing, financial responsibility, and regulatory 
and risk analysis.
    The EPA evaluated Texas' Class VI related Attorney General's 
statement for consistency with 40 CFR 145.24. In an Attorney General's 
statement, the State's top legal officer affirms that applicable State 
law (e.g., statutes, regulations, and judicial decisions) provides 
adequate authority to administer the Class VI UIC program as described 
in the program description and consistent with the EPA's regulatory 
requirements for UIC programs.
    The EPA determined that the Class VI MOA addendum meets the Federal 
requirements at 40 CFR 145.25 for primacy MOAs. The MOA is the central 
agreement setting the provisions and arrangements between the State and 
the EPA concerning the administration and enforcement of the State UIC 
program. The EPA's evaluation of the Class VI MOA addendum included 
ensuring that the MOA addendum contained the appropriate provisions 
pertaining to coordination, permitting, compliance monitoring, 
enforcement, and EPA oversight.
    Texas has demonstrated that it meets all UIC permitting 
requirements found in 40 CFR 145.11 for Class VI permits. Texas' UIC 
Class VI permitting provisions and technical criteria and standards 
meet the Federal requirements in 40 CFR parts 124 and 144 through 146. 
The State has incorporated necessary procedures, pursuant to 40 CFR 
145.12, to support a robust UIC Class VI compliance evaluation program. 
Additionally, Texas has available the necessary civil and criminal 
enforcement authorities pursuant to 40 CFR 145.13. Texas' UIC Class VI 
regulations regarding permitting, inspection, operation, monitoring, 
reporting, and recordkeeping meet Federal requirements found in 40 CFR 
parts 145 and 146.
    As a result of this comprehensive review, the EPA approves Texas' 
program revision application based on the Agency's determination that 
the application meets all applicable requirements for Class VI primacy 
under SDWA section 1422 and EPA's implementing regulations and because 
the State has demonstrated that it is prepared to implement UIC Class 
VI program in a manner consistent with the SDWA and all applicable UIC 
regulations.

D. Public Participation Activities Conducted by the EPA

    On May 8, 2025, the EPA Region 6 Water Division Director sent a 
letter via email to leaders of three tribes in Texas (Alabama-
Coushatta, Kickapoo Traditional, Ysleta del Sur Pueblo) and five in 
Oklahoma that border Texas to the North (Apache, Kiowa Indian, 
Comanche, Chickasaw Nation, Choctaw Nation) offering an opportunity for 
Government-to-Government consultation on Texas' program revision 
application seeking primacy for the UIC Class VI program. On May 20, 
2025, the EPA Region 6 hosted a Tribal informational virtual meeting 
and listening session to provide an overview of the Texas application. 
Three tribes participated in this meeting, Alabama-Coushatta, Ysleta 
del Sur Pueblo, and Choctaw Nation. The EPA provided a description of 
the Federal UIC Class VI program and informed the tribes of its plan to 
soon publish a rule proposing to approve Texas' application. After the 
meeting, the EPA emailed attendees links to current Class VI well data 
in Texas for informational purposes. The EPA received no request for 
tribal consultation during the period beginning May 8, 2025, and ending 
with the close of public comment on August 1, 2025.
    On June 17, 2025, the EPA published a proposed rulemaking in the 
Federal Register (90 FR 25547) proposing to approve Texas' application 
to revise its UIC program to implement the UIC Class VI program within 
the State. The proposal established a 45-day public comment period that 
closed on August 1, 2025. The EPA held a public hearing on July 24, 
2025, that participants could attend virtually, as well as by phone. In 
addition to the Federal Register, the EPA published notice of the 
hearing on the EPA's website and in the Austin American-Statesman, the 
Dallas Morning News, and the Houston Chronicle newspapers.

IV. Public Comments and the EPA's Response

A. Public Comments

    During the public comment period, the EPA received 7,534 written 
comments and 90 oral comments on the proposal from individual citizens, 
energy and industry groups, potential Class VI permittees, 
environmental and civil rights non-government organizations, local 
governments, members of the State Legislature, the Governor of Texas, 
academia, and others. The majority of the written comments the EPA 
received on the proposal were in the form of several ``mass mailing'' 
letter campaigns, including comments from stakeholders supporting 
approval of Class VI primacy for the State of Texas and those opposing.
    The EPA considered these comments in the development of this final 
rule. All comments are available as part of the public record and can 
be accessed through the EPA's docket (ID No. EPA-HQ-OW-2025-0157). 
Documentation of the EPA's public participation activities, including 
comments received and the EPA's comment response document, can also be 
found in the docket (ID. No. EPA-HQ-OW-2025-0157).

B. The EPA's Response to Comments

    The EPA received comments both supporting and opposing the proposed 
approval of UIC Class VI program primacy for the State of Texas, as 
well as some comments outside the scope of the primacy approval action.
    Commenters in support of Texas UIC Class VI program primacy 
approval asserted that the State's application meets all requirements 
at 40 CFR part 145 and SDWA section 1422 and that the RRC has 
demonstrated the ability and authority required for Class VI primacy 
approval. They stated that the RRC is experienced with UIC permitting, 
has a robust UIC permitting program, has effectively regulated deep 
injection wells since 1982, and is familiar with carbon dioxide 
injection via permitting of Class II enhanced oil recovery wells. They 
also asserted that the RRC has the financial resources and capacity to 
ensure thorough Class VI permit application reviews, and that the RRC 
has in-house staff trained in the technical disciplines needed to 
review Class VI permit applications and oversee Class VI well 
operators, as well as a familiarity with Texas' geology and local 
communities and their needs.
    Commenters opposing Class VI primacy approval, including writers of 
mass mailing letters, expressed concerns related to the RRC's ability 
to oversee a Class VI program, alleging past inabilities to inspect 
wells and enforce Class II regulations which, they assert, could impact 
public health and the environment. They alleged the RRC has 
insufficiently investigated complaints or insufficiently enforced 
violations associated with Class II injection wells. Commenters further 
alleged that the RRC does not have a demonstrated history of robust 
public engagement or accessible hearings. Commenters expressed concern 
that the RRC has insufficient financial resources to oversee Class VI 
wells in the State and alleged that the RRC lacks

[[Page 51025]]

independence from political or oil and gas industry influences.
    Comments received outside the scope of this primacy approval action 
included concerns about oil and gas production well plugging and 
abandonment, pipeline safety, environmental impacts on media other than 
USDWs, such as wetlands, surface water, and air, and tax revenues 
associated with the geologic sequestration of carbon dioxide. The EPA 
has noted and addressed all topics, including out-of-scope topics, in 
the Agency's response to comments document included in the docket (ID. 
No. EPA-HQ-OW-2025-0157).

V. The EPA's Action

A. Incorporation by Reference

    The EPA is approving a revision to the State of Texas UIC program 
to give Texas primacy over Class VI injection wells in the State, 
except for those located on Indian lands. This action amends 40 CFR 
147.2200 and incorporates by reference Texas' EPA-approved statutes and 
regulations that contain UIC Class VI standards, requirements, and 
procedures applicable to Class VI owners or operators within the State. 
Any provisions incorporated by reference, as well as all permit 
conditions issued pursuant to such provisions, are enforceable by the 
EPA pursuant to SDWA section 1423, 42 U.S.C. 300h-2, and 40 CFR 
147.1(e). The EPA will continue to administer the UIC program for Class 
I, II, III, IV, V, and VI injection wells on Indian lands. 30 CFR 
147.2205. No Tribe currently has UIC primacy for Indian lands within 
Texas.
    The EPA has compiled the applicable Texas statutes and regulations 
to be incorporated by reference into 40 CFR 147.2200 in a document 
titled ``EPA Approved Texas SDWA Sec.  1422 Underground Injection 
Control Program Statutes and Regulations for Well Class VI,'' dated May 
1, 2025. This compilation is available at https://www.regulations.gov 
in the docket for the proposed rulemaking. With this action, the EPA 
also codifies a table in 40 CFR 147.2200 listing the compiled EPA-
approved Texas statutes and regulations that contain standards, 
requirements, and procedures applicable to owners or operators of Class 
VI wells that the EPA incorporates by reference. Any provision of these 
statutes and regulations that does not contain standards, requirements, 
or procedures applicable to owners or operators of Class VI wells are 
not incorporated by reference.

B. The EPA's Oversight

    The EPA will continue to oversee Texas' administration of its UIC 
program, including by requiring quarterly reports on instances of 
permittee non-compliance and annual UIC performance reports pursuant to 
40 CFR 144.8. The MOA between the EPA Region 6 and the RRC also 
specifies that the EPA will oversee the State's administration of the 
UIC program on a continuing basis to assure that such administration is 
consistent with the program MOA, the SDWA and implementing regulations, 
UIC grant agreements, and other applicable requirements.

VI. Statutory and Executive Order Reviews

    Additional information about these statutes and Executive orders 
can be found at: https://www.epa.gov/laws-regulations/laws-and-executive-orders.

A. Executive Order 12866: Regulatory Planning and Review

    This action is exempt from review under Executive Order 12866, 
because the Office of Management and Budget (OMB) has exempted, as a 
category, the approval of State UIC programs.

B. Executive Order 14192: Unleashing Prosperity Through Deregulation

    Executive Order 14192 does not apply because actions that approve 
State UIC Programs are exempted from review under Executive Order 
12866. This exemption also applies to EPA approvals of revisions to 
existing State UIC programs.

C. Paperwork Reduction Act (PRA)

    This action will not impose an information collection burden under 
the PRA. OMB has previously approved the information collection 
activities contained in the existing regulations and has assigned OMB 
control number 2040-0042. Reporting or recordkeeping requirements will 
be based on Texas' UIC Regulations, and the State of Texas is not 
subject to the PRA.

D. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic 
impact on a substantial number of small entities under the RFA. This 
action will not impose any additional burdens on small entities as this 
action codifies a State program already in effect and transfers primary 
implementation authority from the EPA to a State program with 
substantially the same requirements.

E. Unfunded Mandates Reform Act (UMRA)

    This action does not contain an unfunded mandate as described in 
UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect 
small governments. The action imposes no enforceable duty on any State, 
local, or Tribal governments or the private sector. The EPA's approval 
of Texas' UIC Class VI program will not constitute a Federal mandate 
because there is no requirement that a State establish a UIC regulatory 
program and the program is a State program, rather than a Federal 
program.

F. Executive Order 13132: Federalism

    This action does not have federalism implications. It will not have 
substantial direct effects on the States, on the relationship between 
the National Government and the States, or on the distribution of power 
and responsibilities among the various levels of government.

G. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    This action does not have Tribal implications as specified in 
Executive Order 13175. This action contains no Federal mandates for 
Tribal governments and does not impose any enforceable duties on Tribal 
governments. Thus, Executive Order 13175 does not apply to this action.

H. Executive Order 13045: Protection of Children From Environmental 
Health and Safety Risks

    The EPA interprets Executive Order 13045 as applying only to those 
regulatory actions that concern environmental health or safety risks 
that the EPA has reason to believe may disproportionately affect 
children, per the definition of ``covered regulatory action'' in 
section 2-202 of the Executive Order. This action is not subject to 
Executive Order 13045 because it approves a revision to a State 
program.

I. Executive Order 13211: Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use

    This action is not subject to Executive Order 13211 because it is 
not a significant regulatory action under Executive Order 12866.

J. National Technology Transfer and Advancement Act (NTTAA)

    This rule does not involve technical standards.

K. Congressional Review Act (CRA)

    This final rule is subject to the CRA, and the EPA will submit a 
rule report to each House of the Congress and to the Comptroller 
General of the United States. This action is not a ``major rule'' as 
defined by 5 U.S.C. 804(2).

approval was published in the Federal Register on February 25, 2004, 
with an effective date of March 26, 2004. The UIC program for Class III 
brine mining wells in the State of Texas, except for those wells on
