Work involves cementing an inner casing string to cover a casing hole. The estimated duration of this project is 5 days per well with 10-hour operations from 7:00AM to 6:00PM. The work will be completed in the Fall/Winter/Spring. Work will occur on an existing well pad and will be accessed by existing roadways. There will be no surface disturbance and no change in the utilization of the underground resource. No expansion or new facilities will be required. Electricity will be supplied by the existing infrastructure. The production will be stored, treated, and transported utilizing existing facilities.
The proposed project consists of the California Department of Conservation, Geologic Energy Management Division (CalGEM) approving 2 permits for Sentinel Peak Resources to rework the wells listed below, in the Arroyo Grande 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.

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.

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.
