Dear Administrator Regan,
As Members of the bipartisan House Climate Solutions Caucus, we write to express concerns with delays in the
permitting of underground CO
2
storage and processing of state primacy applications. Additionally, we write to
call attention to the dismal number of Class VI well projects that have been deployed after successfully moving
past the permitting process. We understand that the EPA is currently processing one hundred and eighty-one
Class VI well permit applications alongside at least two state primary authority applications. Permitting delays
are actively crippling U.S. efforts to deploy vital clean energy and carbon capture infrastructure alike. While we
recognize that there are advanced engineering and environmental safety considerations that must be accounted
for in Class VI well permitting and state primacy designation, there is no time to waste in deploying carbon
sequestration infrastructure, which will play a vital role in decarbonizing the U.S. economy. We respectfully
request a comprehensive response outlining the challenges that EPA is facing in meeting its goal of reducing
processing timelines for Class VI well permits and state primacy applications to better understand how
Congress can work to address them.
It is widely recognized that carbon storage solutions will be needed alongside continued efforts to decrease the
U.S. dependency on fossil fuels
1
. As you know, permanent underground carbon injection and storage represents
a readily available option for permanent CO
2
storage while other advanced Carbon Capture, Utilization, and
Sequestration (CCUS) technologies develop and work towards commercialization. The window for impactful
climate action is rapidly closing and it is imperative that the U.S. deploy carbon sequestration infrastructure as
quickly as possible. Accordingly, permits for carbon sequestration projects such as Class VI wells need to be
processed in a timely manner so that their construction and operation can get underway. Congruently, state
legislation and capacity need to be developed more rapidly under EPA guidance in order for states to be granted
primacy and take on Class VI well permitting themselves.
In recent years, Congress has funded projects and programs aimed at spurring investment in, and the
deployment of, carbon sequestration technologies and associated infrastructure. Most recently, the IRA included
a significant bump in funding for the 45Q carbon sequestration tax credit
2
. These funds, alongside investments
made through the Bipartisan Infrastructure Law (BIL) have led to rapid private sector investment in the CCUS
space and a significant increase the number of Class VI permits in the EPA queue
3
. However, of all the Class VI
permits received by EPA in the past 13 years, only 8 have been approved, with each taking anywhere from three
to six years to reach a final permitting decision
4
. Of the approved Class VI permit applications, half have moved
forward and only two projects are in operation. The remaining two were only issued permits as recently as the
end of January 2024. These statistics speak to the difficulty that even a well-understood method of carbon
storage faces in successfully navigating the U.S. permitting landscape in its current form.
