Project Updates
Air Products is committed to open and continuous engagement with residents, local governments, and civic and community organizations. We view it as very important to the community to make ourselves available, and in true Air Products spirit, our efforts go beyond the regulatory requirement for this project.
Air Products is an extremely safety-oriented company when it comes to our people, the surrounding community and its residents, and the environment, and we will continue outreach to talk about the project and its environmental and economic benefits. We also are required to maintain a continuous public awareness program in accordance with the Code of Federal Regulations (CFR) in order to operate. This includes continuous engagement with emergency responders.
In addition to the extensive monitoring required of Air Products during sequestration, the company is required to monitor the area for 50 years after injection of CO₂ has ended.

Beginning Work for Two Test Well Locations is Underway
In addition to the subsurface survey, Air Products has begun preliminary work to install two stratigraphic test wells on Lake Maurepas. The purpose is to further confirm the geology beneath Lake Maurepas as suitable for permanent sequestration of CO₂.
Air Products received the necessary permits to conduct this test well work in the lake's south location from the U.S. Army Corps of Engineers and the Louisiana Office of Coastal Management.
The test wells and associated activities are not expected to increase the noise or adversely affect access for residents or recreational and commercial users of Lake Maurepas.
The proposed activities would be conducted in phases to avoid disruptions to normal lake and adjacent marsh access.
Activities will include deepening two sections of an existing channel that will be used for barge and drill rig access to Lake Maurepas, well pad construction, well installation at two proposed locations and a staging area at Port Manchac.
A staging area will be located at the Port Manchac facility; no modifications will be made to existing facilities.
Minor dredging and propwash preliminary work began September 16 and will end October 27, 2022. The work is being conducted to allow access for a drilling rig and rock barge. The barge will enter Lake Maurepas from Lake Pontchartrain via Pass Manchac. Tugs will be used to move the barge through the navigation channel.
Dredging will only be implemented on Lake Pontchartrain near the entrance to Pass Manchac.
Propwash will be used to improve passage at one location on Lake Maurepas near the entrance to Pass Manchac (west of Akers).
Propwash will also be utilized to prepare the drill pad locations at the south and north test well sites.
Total dredging and propwash is approximately 39,700 cubic yards, placing the coverage under programmatic general permit (PGP#1).
Other channel improvements include stump removal.
The south test well drilling will start in November 2022. The north test well drilling will start in January 2023. These activities will be completed in April 2023.
A 16’ X 7’ platform will be installed to protect the test well locations.
The completed wells may be left in place for potential use as sequestration monitoring wells if testing confirms the geology is suitable for carbon sequestration.
A supplemental plan for plugging, capping, and/or removing the test wells will be provided if the area is deemed unsuitable for carbon sequestration.

Lake Maurepas Seismic Survey Work
Air Products will construct a state-of-the-art clean energy complex in Ascension Parish. This clean energy complex will make Louisiana a leader in the U.S. clean energy transition. The project will produce clean hydrogen and feature the world’s largest site for carbon dioxide (CO2) capture and permanent sequestration. Carbon sequestration is permanent, proven and an environmentally sound disposition of CO2. Louisiana’s geology is some of the best in the world for sequestration. Approximately 95 percent of the CO2 generated at the new facility will be captured, compressed, and transported safely to permanent sequestration sites (geologic pore space) beneath Lake Maurepas. Air Products has received approval from the State Mineral and Energy Board – part of the Louisiana Department of Natural Resources – for the permanent sequestration of the CO2 in this area. The permanent sequestration area is approximately one mile beneath the surface and will have no effect on water tables. A seismic survey of Lake Maurepas is to begin in October 2022 through Spring 2023. A seismic survey is a 3D visual safety inspection of underground geology to help ensure the safest places to permanently store CO2 are assessed and confirmed. This survey is required as part of the permitting process.
The survey will be conducted by Exoduas Inc. in six phases, allowing continued boating access and recreation on the lake. Sound waves similar to a fish finder will produce 3D images of underground geologic structures. These sound waves are produced using small charges 60 feet beneath the water bottom. Passive receiver units called “nodal geophones” will record sound waves from the source points to map the subsurface formations in the area. Receivers are approximately 8” high and 3” in diameter and will be placed on cane poles (seismic source location markers) at the surface of the water and on land areas north and southeast of the lake.
