Carbon capture and storage (CCS) is rapidly emerging as one of the most consequential areas of energy law and environmental regulation. At its heart sits a technical but critically important regulatory category: the Class VI injection well. These wells are used to inject carbon dioxide into deep rock formations for the purpose of long-term underground storage, making them the cornerstone of any commercial-scale CCS project. For years, permitting authority for Class VI wells located in Texas rested solely with the federal Environmental Protection Agency (EPA), resulting in a process many in the energy industry found slow and uncertain.

That all changed last fall. In November 2025, the State of Texas formally received primary enforcement authority, or “primacy”, for its Class VI Underground Injection Control (UIC) program, granting the Railroad Commission of Texas (RRC) regulatory power over these types of wells and, consequently, the CCS process.

This article examines how Texas achieved this milestone, how the state strategically positioned itself for a seamless transition by accepting applications and fees years in advance, and the status of those permit applications today.

When President Jimmy Carter installed rooftop solar panels on the White House, public support for adoption of renewable energy was at a then all-time high and many imagined the possibility of rooftop solar on their own homes and in their own communities. Yet, barriers such as the high up-front installation cost of panels, and of…

On January 18, 2023, the U.S. Environmental Protection Agency (“EPA”) and the Department of the Army published a new final rule to re-define “waters of the United States” (“WOTUS”) under the Federal Clean Water Act (“CWA”). Although the rule is set to take effect March 20, 2023, the looming U.S. Supreme Court decision in Michael Sackett, et ux v. EPA, et al., Docket No. 21-454(2022) could establish additional legal precedent as to what constitutes WOTUS and could enable further legal challenges to the rule. If the rule goes into effect, it would broaden the types of water bodies subject to CWA regulation, while providing some clarity with regard to some newly excluded water features.

The Environmental Protection Agency (“EPA”) released its most recent proposal for controlling greenhouse gas emissions produced by the oil and gas industry earlier this month. The supplemental proposal builds upon the comments received by EPA in response to its proposed emission-control rules issued under Section 111 of the Clean Air Act (“CAA”) on November 15, 2021. In particular, the supplemental proposal revises and expands the stringent emissions control program introduced one year ago for new and existing sources. The supplemental proposal, however, raises questions regarding the implementation of existing greenhouse gas reporting and fee requirements under the Inflation Reduction Act (“IRA”). 

On September 21, 2022, the Senate passed the Kigali Amendment to the 1987 Montreal Protocol (which had been signed by former President Obama in 2016) by a vote of 69 to 27, reaffirming U.S. commitment to the reduction of hydrofluorocarbons (“HFCs”) through multiple processes (some of which are already causing shifts in import and export markets, as well as in the consumer market).   

On December 7, 2021, the U.S. Environmental Protection Agency (“EPA”) released its proposed 2020, 2021, and 2022 Renewable Volume Obligations (“RVOs”). RVOs determine the amount of renewable fuel (typically, ethanol) certain fuel refiners and others involved in the transportation fuel supply chain (“Obligated Parties”) are required to blend into their own fuel production during a given year. Obligated Parties failing to meet their RVOs for any year must buy Renewable Identification Numbers (“RINs”) or other credits, or risk default under the Renewable Fuel Standard (“RFS”).

Pursuant to the Renewable Fuel Standard (“RFS”), the U.S. Environmental Protection Agency (“U.S. EPA”) issues annual renewable volume obligations (“RVOs”), which set the minimum aggregate volume of renewable fuel that refiners must blend with transportation fuel for the following calendar year.

Refineries producing transportation fuel meet their RVOs by blending the required volume of renewable fuel into gasoline or diesel fuel or by acquiring credits (called renewable identification numbers, or “RINs”). The RFS permits “small” refineries – those producing fewer than 75,000 barrels of fuel per day – to claim an exemption by showing that meeting their RVOs would cause them “disproportionate economic hardship.”

Recent Regulatory Steps

On January 14, 2021, on the eve of President Biden’s inauguration, EPA issued an advance notice of proposed rulemaking, seeking comment on whether PFOA and PFOS should be regulated under the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) and the Resource Conservation and Recovery Act (“RCRA”). This will likely lead to the designation of PFOA and PFOS as “Hazardous Substances” under CERCLA and RCRA. Such a designation will likely lead to EPA and the state agencies taking more aggressive action to investigate and identify new sites where PFAS may be a concern and also to review the status of existing sites where PFAS may be a concern that was not addressed in previous investigations or response actions and to potentially pursue response actions at such sites.  At this moment though there is only the interim policy that EPA provided to assist in addressing PFOA and PFOS groundwater contamination. The comment period on this advance notice just closed and we anticipate a proposed rulemaking in the near future.
