It has been granted a Notice of Exemption from full environmental review under the California Environmental Quality Act (CEQA), specifically falling under Group B of CalGEM's rework exemptions and CEQA categorical exemptions Classes 1, 2, 4, 7, and 8. These exemptions are based on the determination that the project involves minor alterations to land and the replacement of existing structures with negligible environmental impact. Administrative oversight is managed by CalGEM's Southern District in Long Beach, California, with Hafiz Ali Mohammed serving as the certifying official.
