EPA Accepts Comment on Tentative Research Permits for Climate Change
Mitigation Study off the Coast of Cape Cod
WASHINGTON – Today, May 30, the U.S. Environmental Protection Agency is
inviting public comment on two tentative permits under the Marine
Protection, Research and Sanctuaries Act for a research study on a
potential climate change mitigation technique referred to as ocean alkalinity
enhancement. The research study is proposed by a researcher at Woods Hole
Oceanographic Institution.
The proposed research is part of Woods Hole Oceanographic Institution’s
“LOC-NESS Project.” The applicant and their research team are interested
in studying a potential climate change mitigation technique referred to as
ocean alkalinity enhancement, which may result in possible removal and storage
of carbon dioxide from ocean waters. The study would advance scientific
knowledge of an ocean alkalinity enhancement method and its potential impacts
to human health, the marine environment, and other uses of the ocean. The EPA
does not anticipate any measurable environmental or other impacts beyond the
monitoring periods of the study.
Under the Marine Protection, Research and Sanctuaries Act, the EPA has the
authority to issue research permits for the transportation and disposition of
materials into the ocean for a research study when it is determined that the
scientific merit of the proposed project outweighs the potential environmental
or other damage that may result from the activities. While the EPA has issued
many research permits under the Marine Protection, Research and Sanctuaries
Act, if issued, these would be the first permits by the agency to authorize
this kind of research project studying ocean alkalinity enhancement.
The EPA welcomes comments on the tentative permits. Information on the
proposed research activities and the EPA’s tentative determination to issue
these permits are available on the Federal Rulemaking Portal Docket ID
Nos. EPA-HQ-OW-2023-0591 and EPA-HQ-OW-2024-0189. The EPA will consider all
comments received during the public comment period to inform the final
determinations and conditions for the permitted activities.
Woods Hole Oceanographic Institution has proposed a two-phased study. Phase 1
would occur over several days in the summer of 2024 south of Martha’s
Vineyard (approximately 9.5 miles south of the nearest shoreline in Nomans
Land Island, Massachusetts). Phase 2 would occur over several weeks in the
summer of 2025 within the Wilkinson Basin (approximately 38 miles from the
nearest shoreline in Cape Cod, Massachusetts). Both phases of the study would
involve a controlled release of a sodium hydroxide solution, an alkaline
liquid, into surface ocean waters and multi-day monitoring of temporary shifts
in water chemistry and other environmental changes.
The EPA is hosting a virtual listening session on June 17, 2024, from 6:00
p.m. to 7:30 p.m. EDT to share information on both phases of the proposed
research activities and the EPA’s tentative determinations. All persons who
wish to participate in the listening session must register in advance.
Background
There is a growing interest from federal agencies, researchers, industry and
non-governmental entities to research marine carbon dioxide removal
techniques, such as ocean alkalinity enhancement, that have the potential to
mitigate the adverse impacts of climate change. The EPA recognizes that
research is needed to better understand the effectiveness of potential marine
carbon dioxide removal techniques for mitigating the impacts of climate change
and to understand the potential environmental benefits and risks of
implementing these approaches. Depending on project specifics, a permit may
be required for marine carbon dioxide removal activities in coastal waters or
the ocean under permitting programs administered by the agency. Additional
information is available on the EPA’s website for permitting of marine
carbon dioxide removal activities.
