The project is situated on private surface and private minerals and will be conducted entirely on an existing pad to ensure no disturbance to undisturbed areas and no additional construction. The project has received a California Environmental Quality Act (CEQA) Notice of Exemption, certified on November 10, 2025, under several classes including Class 1, 2, 4, 7, and 8.

The proposed rework falls under Group A of the CalGEM rework exemptions guidance. Administrative oversight is provided by the California Department of Conservation, Geologic Energy Management Division (CalGEM), with the specific place of performance located at Latitude 35.0610046 and Longitude -119.2197113.
