Rework to Repair Well Casing on Island Grissom within THUMS Operating Area

THUMS Long Beach Company proposes to rework oil and gas well A-868 (API #0423700611) located on Island Grissom within the Wilmington Oil Field in Los Angeles County, California. The project involves repairing the existing wellbore by cementing a 5.5 inch casing sleeve to address well integrity issues, ensuring the well can safely return to its existing use without increasing its surface footprint or production output. The work is confined to an existing well pad within an industrial zone and is classified as maintenance of an existing facility. The California Department of Conservation, Geologic Energy Management Division (CalGEM) serves as the regulatory authority and has issued a Notice of Exemption dated August 4, 2025. This notice determines that the project is exempt from full environmental review under the California Environmental Quality Act (CEQA), citing categorical exemptions for existing facilities, replacement or reconstruction, and minor alterations to land. The project must adhere to CalGEM regulations and SB 1137 health and safety standards. While Gregory S. Berg of CalGEM is the certifying official, the documentation does not include specific financial terms, contract values, or federal acquisition clauses, as it primarily functions as a regulatory approval and environmental exemption.
