Document Description
The project consists of reworking an existing oil production well by perforating a scab liner, placing cement plugs, perforating casing, and running a gravel pack. No permanent facilities will be constructed, and no expansion of associated facilities will be required. Various mobile temporary equipment will be used including, but not limited to, drilling rig, workover rig, etc., and vehicles to transport personnel and materials to/from the site. There will not be new ground surface disturbance associated with this project.
CalGEM has approved permits for THUMS Long Beach Co. to rework the oil and gas well listed below, in the Wilmington oilfield.

Class 1: California Code of Regulations, title 14, section 15301
Reasons for Exemption
The project is categorically exempt from CEQA under the “Class 1” (14 CCR § 15301) exemption per the CEQA Guidelines because this rework could be considered maintenance of the well in order to ensure continued operation by replacing existing, similar equipment (liners, etc.). Specifically, the purpose of the rework is to conduct maintenance to ensure continued operations. The use of the well and capacity of the operation is limited by the existing permits for UIC projects 849-45-001 and 849-48-001 and engineering summary indicates the proposed work is within the scope of those approvals.

Class 2: California Code of Regulations, title 14, section 15302
Reasons for Exemption
The project is categorically exempt from CEQA under the “Class 2” (14 CCR § 15302) exemption per the CEQA Guidelines because this is a rework that only involves replacing similar existing equipment and structures (perforations) of an existing production well and does not propose changes to the structure of the well (the wellbore). The location of the well will not change, nor will the purpose of the well, which is production. After the rework, the well will have substantially the same capacity. The use of the well and capacity of the operation is limited by the existing permits for UIC projects 849-45-001 and 849-48-001 and engineering summary indicates the proposed work is within the scope of those approvals.

Class 4: California Code of Regulations, title 14, section 15304
Reasons for Exemption
The project is categorically exempt from CEQA under the “Class 4” (14 CCR § 15304) exemption per the CEQA Guidelines because the project would be conducted entirely on an existing pad of sufficient space enough to contain all equipment and existing roads to the pad would be utilized with no new disturbance. No impacts to biological resources are expected. The Project would not disturb any undisturbed areas, and is located within an industrial area and would, as per CalGEM “consists of drilling operations that result in only minor alterations with negligible or no permanent effects to the existing condition of the land, water, air, and/or vegetation.” The rework would not expand the facility and is conducted in order to maintain level of service.
