Document Description
The project involves the rework of a well to squeeze perforations with cement. Work will occur on an existing well pad. There is no surface disturbance associated with this project 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. This request is for the appropriate CalGEM permit to rework wells identified below. Work involves plugging perforations with a cement squeeze. 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 1 permit for Sentinel Peak Resources California LLC to rework the well listed below, in the Arroyo Grande Oil Field.

Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
14 CCR §§ 15301, 15302, 15304, 15307 and 15308
Reasons for Exemption
Class 1, Existing Facilities (14 CCR §§ 15301, 1684.1):
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):
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.
Class 4, Minor Alterations to Land (14 CCR §§ 15304, 1684.2):
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.
Classes 7 and 8, Actions by Regulatory Agencies for Protection of Natural Resources and the Environment (14 CCR §§ 15307, 15308):
Class 7 and Class 8 exemptions apply. The exemptions are for actions taken by regulatory agencies as authorized by law to assure the maintenance, restoration, enhancement, or protection of a natural resource or the environment where the regulatory process involves procedures for the protection of the environment.” As demonstrated in the record, the proposed project involves remedial/rework operations to address well integrity issues that requires swift action for protection of a natural resource and the environment.
