Document Description
Signal Hill Petroleum, Inc (“SHP”) proposes to investigate and repair well SHCU 27-7. This project will require a workover rig and vendor equipment to investigate and repair possible casing damage between 2890’ and 2981’ in accordance with current regulatory standards.
No vegetation will be disturbed. No environmental impact is expected. The existing well site can accommodate the rig, staging of materials, other equipment, and worker parking. The work process is expected to require approximately 2 weeks in total.
The project’s temporary equipment includes a rig and various vehicles to transport personnel, materials, mobilize and demobilize equipment and transport waste. Rig and associated equipment will be transported to the site via public and/or private roadways in a manner that ensures the safety of the public and protection of the environment. The rig and all ancillary and transportation equipment will be fully compliant with air quality regulations. SHP’s rig fleet and service vehicles are in full compliance with CARB and South Coast AQMD requirements. Additionally, vehicles participate in the California Highway Patrol BITs program.
The proposed project consists of the California Department of Conservation, Geologic Energy Management Division (CalGEM) approving one permit for Signal Hill Petroleum, Inc. to rework the well listed below, in the Long Beach 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.

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.

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.
