Document Description
Southern California Gas Company (SoCalGas) proposes?to?workover?a?gas storage well. Proposed work will be performed?using a service rig?as well as temporary equipment such as a mud pump and return bins. Work will involve performing casing expansions and installing new completion equipment.
The gas storage well, WEZU C-3B, is located in Los Angeles County. The proposed work would take place on an existing well pad which is flat and large enough to accommodate the necessary equipment and can be accessed by existing roads. The surrounding gas field consists of other graded pads, wells, equipment, and roadways with areas of undisturbed non-native grasses and California sage brush vegetation. No permanent facilities will be constructed during the process, and no expansion of associated facilities will be?required.?The well would remain a gas storage well with?substantially the?same capacity.?There would be no new surface disturbance that would significantly?impact?biological resources or their habitat.
The proposed project consists of the California Department of Conservation, Geologic Energy Management Division (CalGEM) approving 1 permit for Southern California Gas Company to rework the well listed below, in the Honor Rancho Gas Field in Los Angeles County.

Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
Class 1, Existing Facilities (14 CCR §§ 15301, 1684.1)
Reasons for Exemption
The project is categorically exempt from CEQA under the “Class 1” (14 CCR § 15301) exemption per the CEQA Guidelines because the proposed project is a repair or minor alteration of existing facilities and will not involve an expansion of use of the gas field beyond that existing previously, and therefore is exempt from the need for full CEQA review. This includes “publicly owned utilities used to provide electric power, natural gas, sewerage, or other public utility services.” (14 CCR § 15301(b)). The project proposes to make minor alterations to an existing gas storage well by performing casing expansions and installing new completion equipment. The well would remain a gas storage well with substantially the same purpose and capacity.

Categorical Exemption
Type, Section or Code
Class 2, Replacement or Reconstruction (14 CCR § 15302)
Reasons for Exemption
Class 2 applies because the proposed project consists of “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.” (14 CCR § 15302.) The proposed project would reconstruct the casing of an existing gas storage well, which is located on an existing well pad. The well would remain a gas storage well with substantially the same capacity.
Exempt Status
Categorical Exemption
Type, Section or Code
Class 4, Minor Alterations to Land (14 CCR §§ 15304, 1684.2)
Reasons for Exemption
Class 4 exemption applies because the proposed 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.” (14 CCR §1684.2.) The proposed project would rework an existing gas storage well. The well would remain a gas storage well with substantially the same capacity. The well is located on an existing well pad, which is large enough to accommodate the necessary equipment and can be accessed by existing access roads. The project does not involve the construction of new facilities or the expansion of existing facilities. Therefore, there would be no new surface disturbance that would significantly impact the surrounding environment.
