Document Description
Aera Energy LLC (Aera) proposes to rework six existing production wells located in the San Ardo Oil Field. The proposed reworks consist of adding perforations, temporary plugback, and pulling and replacing the existing liner. Temporary equipment for the project would include a workover rig, wireline unit, cementing equipment, pump, tank, pickup truck, and delivery truck. The entirety of this work is in an area of existing disturbance, and no change in the surface topography (such as drainage patterns) is included in the work design. No new grading would occur in undisturbed areas. Regular operations at the site would include removal of weeds and other ruderal vegetation for fire control and road maintenance.
The work would occur on existing well pads and work locations would be accessed using existing access roads. The work would involve installation of various above-ground piping to connect well sites to existing infrastructure. No new infrastructure would occur as a result of the work.
The proposed project consists of the California Department of Conservation, Geologic Energy Management Division (CalGEM) approving six permits for Aera to rework the wells listed below, in the San Ardo Oil Field in Monterey County.

Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
Class 1: California Code of Regulations, title 14, section 15301
Reasons for Exemption
The project is exempt under the Class 1, Existing Facilities exemption because the project would make minor changes to existing wells involving no expansion of the existing use of the wells. Class 1 exemption consists of operation, repair, maintenance, or minor alternation 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 “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 project consists of adding perforations, temporary plugback, and pulling and replacing the existing liner. No expansion of the existing well pads, roads, staging areas, or pipelines are proposed, and the completion design would be the same as the original wellbores. According to a CalGEM engineer, the proposed work is within the scope of UIC project 64403002 and would be a continuation of operations within the confines of the UIC project as permitted by the project approval letter (PAL). Therefore, the changes to the existing facilities would be negligible and would not expand the existing use.
Exempt Status
Categorical Exemption
Type, Section or Code
Class 2: California Code of Regulations, title 14, section 15302
Reasons for Exemption
Class 2 exemption applies because it 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[.]” Examples of Class 2 include, but are not limited to, “[r]eplacement or reconstruction of existing utility systems and/or facilities involving negligible or no expansion of capacity.” (14 CCR § 15302.) The project consists of adding perforations, temporary plugback, and pulling and replacing the existing liner, and the completion design would be the same as the original wellbores. According to a CalGEM engineer, the proposed work is within the scope of UIC project 64403002 and would be a continuation of operations within the confines of the UIC project as permitted by the PAL. Therefore, the proposed project consists of replacement or reconstruction on the same site and would not change the purpose or capacity of the wells.
Exempt Status
Categorical Exemption
Type, Section or Code
Class 4: California Code of Regulations, title 14, section 15304
Reasons for Exemption
Class 4 exemption applies. 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 would be conducted entirely on existing pads with enough space to contain all equipment. The project consists of adding perforations, temporary plugback, and pulling and replacing the existing liner, and the completion design would be the same as the original wellbores. No expansion of the existing well pads, roads, staging areas, or pipelines are proposed. The proposed project is located within a developed oil field. Therefore, the proposed project would result in only minor alterations with negligible or no permanent effects to the existing condition of the land, water, air, and/or vegetation.
Exceptions to Exemptions: CalGEM further finds that there are no exceptions to the application of the categorical exemptions (PRC § 21084; 14 CCR § 15300.2) referenced above. For example, there is no substantial evidence that there are any “unusual circumstances” associated with the proposed project that create a reasonable possibility that the activity will have a significant effect on the environment, and that there are no significant “cumulative impacts” resulting from successive projects of the same type in the same place. Therefore, reliance on the exemptions is appropriate.
