Document Description
The Operator proposes to rework an existing gas storage well by perforating and cementing the casing and completing the well with a new liner and tubing. The work would take place on an existing well pad, and no new construction would be required. This rework would remediate a known integrity issue and would not change the purpose or capacity of the well.
The proposed project consists of the California Department of Conservation, Geologic Energy Management Division (CalGEM) approving 1 permit for PG&E to rework the well listed below, in the Los Medanos Gas Field in Contra Costa County.

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.” (14 CCR § 1684.1.) This includes “publicly-owned utilities used to provide electric power, natural gas, sewerage, or other public utility services.” (14 CCR 15301(b).) The Operator proposes to rework an existing gas storage well by perforating and cementing the casing and completing the well with a new liner and tubing.

Class 2, Replacement or Reconstruction (14 CCR § 15302)

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.) The proposed project would rework an existing gas storage well. 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.
