The US Environmental Protection Agency (EPA) has announced its intent to issue three Underground Injection Control (UIC) Class VI permits to ExxonMobil Low Carbon Solutions Onshore Storage LLC, paving the way for a major carbon capture and storage (CCS) project near Fannett, Texas.
The proposed permits mark a significant step in ExxonMobil’s plans to sequester carbon dioxide deep underground in Jefferson County.
The three wells—designated Rose CCS No. 01, 02, and 03—are designed to inject CO2 into geologic formations for long-term storage.
If finalized, the permits will allow ExxonMobil to proceed with construction and operation of the injection wells under strict EPA oversight to ensure protection of underground sources of drinking water.
The EPA’s Region 6 office, which oversees permitting in Texas, stated that each well must comply with rigorous monitoring, reporting, and safety requirements as laid out under the Safe Drinking Water Act and federal UIC regulations.
These include periodic updates to the agency to confirm ongoing environmental integrity of the site. In accordance with federal regulations, the EPA has opened a 30-day public comment period, offering residents and stakeholders an opportunity to weigh in on the proposed permits.

The comment window runs through August 4, 2025, at 11:59 pm CST. A virtual public hearing is scheduled for July 31, 2025, where community members will be able to offer comments directly to EPA officials.
The agency also noted that translation services and accessibility accommodations will be available for both the hearing and a prior informational public meeting.
The proposed project is part of ExxonMobil’s broader effort to scale carbon capture and storage technologies across the Gulf Coast region — a strategy the company says is essential for meeting national emissions reduction goals.
More details on how to submit written comments or register for the virtual hearing can be found on EPA Region 6’s website.
