Section 400-8-1-.22 - [Effective 1/11/2025] Delineation of Storage Facility Area and Area of Review

In connection with the boundaries of the storage facility area and area of review, the storage operator shall perform the following actions:

1. Predict, using existing site characterization, monitoring and operational data, and computational modeling, the projected lateral and vertical migration of the carbon dioxide plume and its associated pressure front in the subsurface from the commencement of injection activities until the plume movement ceases, or until the end of a fixed time period as determined by the Board. The model must:

a. Be based on detailed geologic data collected to characterize the injection zone, confining zone, and any additional zones; and anticipated operating data, including injection pressures, rates, and total volumes over the proposed life of the geologic sequestration project;

b. Take into account any geologic heterogeneities, other discontinuities, data quality, and their possible impact on model predictions; and

c. Consider potential migration through faults, fractures, and artificial penetrations.

2. Using methods approved by the Board, identify all penetrations, including active and abandoned wells and underground mines, in the storage facility and the area of review that may penetrate the confining zone. Provide a description of each well's type, construction, date drilled, location, depth, record of plugging and completion, and any additional information the Board may require.

3. Determine which abandoned wells have been plugged or operating wells have been constructed in the storage facility area and the area of review in a manner that prevents the movement of the injected carbon dioxide or other fluids that may endanger underground sources of drinking water, including use of materials compatible with the carbon dioxide stream.
