LBTH Inc. is the operator of the Vasquez W.D. 1-17 water disposal well located in the Del Valle Field, Los Angeles County, as part of Underground Injection Project 1980002. The California Department of Conservation, Geologic Energy Management Division (CalGEM) determined that existing project files lacked sufficient data to confirm that the injection zone does not contain an underground source of drinking water (USDW), which is defined as containing fewer than 10,000 milligrams per liter of total dissolved solids. To comply with California Code of Regulations title 14, sections 1724.6 and 1724.7, the operator submitted a Notice of Intent to conduct water sampling at the Vasquez 12-17 offset well to provide the necessary access to the injection zone. The project, identified as 658706_LBTH_UIC, was certified on August 11, 2025. It has been granted a California Environmental Quality Act (CEQA) Notice of Exemption based on categorical exemptions for existing facilities, replacement or reconstruction, and minor land alterations. The primary deliverable is a representative water sample from the injection zone to guide regulatory actions for public health and environmental safety. While the project is managed by CalGEM in Sacramento, the physical performance occurs at the Vasquez 12-17 well in Los Angeles County. No specific contract value, federal acquisition regulations, or formal procurement clauses are associated with this regulatory work authorization.
