Document Description
Chevron proposes to rework (salvage perforate) 14 existing wells in the heavily developed Midway-Sunset oil field to continue oil and gas resource development. Due to the proximity of wells to each other in an already disturbed, densely developed, and active Midway-Sunset oil field, they are grouped in this application. All perforations will be within the existing completion zone. Water used during the rework operations will be metered, reclaimed produced water, approximately 750 barrels, each well. The work will not increase the depth of any well.
The proposed project consists of the California Department of Conservation, Geologic Energy Management Division (CalGEM) approving 14 permit(s) for Chevron U.S.A. Inc. to rework the well(s) listed below, in the Midway-Sunset Oil Field.

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 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.” This includes “remedial, maintenance, conversion, and abandonment work on oil, gas, injection, and geothermal wells involving the alteration of well casing, such as perforating and casing repair, removal, or replacement; installation or removal of downhole production or injection equipment, cement plugs, bridge plugs, and packers set to isolate production or injection intervals.” (14 CCR § 1684.1.) The proposed project would make minor alterations to the well(s), resulting in negligible expansion of use beyond that existing previously. The proposed project and related permit approval is consistent with the laws that govern the operations, including statutory and regulatory provisions that protect public health, safety, and the environment.
Exempt Status
Categorical Exemption
Type, Section or Code
Class 2, Replacement or Reconstruction (14 CCR § 15302)
Reasons for Exemption
Class 2 consists of 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[.]” (14 CCR § 15302.) The proposed project would reconstruct the casing and wellbore(s) of existing wells. The work would take place on the existing wellbore(s) and well pads. The proposed work involves negligible change in use of the wells. The proposed project and related permit approval is consistent with the laws that govern the operations, including statutory and regulatory provisions that protect public health, safety, and the environment.
Exempt Status
Categorical Exemption
Type, Section or Code
Class 4, Minor Alterations to Land (14 CCR §§ 15304, 1684.2)
Reasons for Exemption
Class 4 consists of “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.” (14 CCR § 1684.2; see also 14 CCR § 15304.) The proposed project involves negligible or no vegetation removal, expansion of the existing well pads, and ground disturbance. Therefore, there would be no surface disturbance related activities that would significantly disturb the surrounding environment. The proposed project and related permit approval is consistent with the laws that govern the operations, including statutory and regulatory provisions that protect public health, safety, and the environment.
