Document Description
The originally approved project consists of reworking (running a pre-packed liner) an existing oil & gas well. 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. Any waste materials will be properly disposed of in accordance with all applicable laws and regulations.
CalGEM has approved permits for THUMS Long Beach Co. to rework the oil and gas well listed below, in the Wilmington oilfield.

Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
Class 1: California Code of Regulations, title 14, section 15301
Reasons for Exemption
Class 1, Existing Facilities (14 CCR §§ 15301, 1684.1): Class 1 exemption may apply as CalGEM’s regulations state: “Class 1 consists of the operation, repair, maintenance, or minor alteration of existing public or private structures, facilities, mechanical equipment, or topographical features involving negligible or no expansion of use beyond that existing previously. The Class includes, but is not limited to: remedial, maintenance, conversion, and abandonment work on oil, gas, injection, and geothermal wells…”. This rework could be considered maintenance of the well in order to ensure continued operation by replacing existing, similar equipment (liner). Specifically, the purpose of the rework is to run a pre-packed liner within the existing wellbore. No changes to the wellbore are proposed. Because the project is to replace existing equipment without changes to the structure of the well (the wellbore) and to ensure its continued operation as a production well, there is no expansion of use beyond that previously existing.

Type, Section or Code
Class 2: California Code of Regulations, title 14, section 15302
Reasons for Exemption
Class 2, Replacement or Reconstruction (14 CCR § 15302): It is also a potential Class 2 as a rework of a well could be considered “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”. This is a rework that only involves running a pre-packed liner to replace similar existing equipment of an existing production well and does not proposed changes to the structure of the well (the wellbore). The location of the well will not change, nor will the underground structure of the well (the wellbore) change, nor will the purpose of the well, which is production. After the rework, the well will have substantially the same capacity.
Exempt Status
Categorical Exemption
Type, Section or Code
Class 4: California Code of Regulations, title 14, section 15304
Reasons for Exemption
Class 4, Minor Alterations to Land (14 CCR §§ 15304, 1684.2): It is also a possible Class 4. The project would be conducted entirely on an existing pad of greater than 0.5 acres (enough to contain all equipment). The project would not disturb any undisturbed areas. The project is located within an industrial area. Therefore, the project “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.
