Document Description
The originally approved project consists of reworking an existing oil and gas production well by installing and cementing a casing sleeve. Project passes through UIC project 84939005. Temporary equipment such as pumps and return bins may be needed. No permanent facilities will be constructed. 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 oil field. API #: 0403723580 Well Name: J-144

Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Class 1, Existing Facilities (14 CCR §§ 15301, 1684.1)
Reasons for Exemption
Class 1, exemption consists of the “operation, repair, maintenance, or minor alterations” of existing structures involving “negligible or no expansion of use beyond that existing previously.” The proposed project is a minor alteration that involves installing and cementing a casing sleeve with the purpose of continuing resource development. The rework does not propose any changes to the wellbore or structure of the well. The well is and would remain a production well with substantially the same production capacity, therefore there is no expansion of use beyond that existing previously. A CalGEM engineer has confirmed the proposed work is within the scope of the existing UIC project 84939005.

Exempt Status
Categorical Exemption
Type, Section or Code
Class 2, Replacement or Reconstruction (14 CCR § 15302)
Reasons for Exemption
Class 2, exemption applies to the “replacement or reconstruction of existing structures and facilities where the new structure will be located on the same site as the structure replaced and will have substantially the same purpose and capacity as the structure replaced.” The proposed project would reconstruct the existing production well by installing and cementing a casing sleeve to continue development and restore production. The project is located on an existing wellpad and does not involve the construction or expansion of facilities, including roads. The well is and would remain a production well with substantially the same capacity. A CalGEM engineer has confirmed the proposed work is within the scope of the existing UIC project 84939005.

Exempt Status
Categorical Exemption
Type, Section or Code
Class 4, Minor Alterations to Land (14 CCR §§ 15304, 1684.2)
Reasons for Exemption
Class 4 applies to “drilling operations that result only in minor alterations with negligible or no permanent effects to the existing condition of the land, water, air, and/or vegetation.” The project is a minor alteration involving installing and cementing a casing sleeve to an existing structure that involves no temporary or permanent surface disturbance related activities that would affect the existing environmental conditions. The project does not involve construction of new facilities or expansion of existing facilities, including roads. The purpose of the proposed project is the continuation of operations within the confines of an existing UIC project with negligible or no permanent effects to the existing condition of the land. The proposed activity’s impacts would be consistent with or a continuation of the baseline conditions.
