Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Class 1: California Code of Regulations, title 14, section 15301
Reasons for Exemption
Class 1, Existing Facilities (14 CCR §§ 15301, 1684.1): Class 1 exemption applies as CalGEM’s regulations state: “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. The Class includes, but is not limited to: remedial, maintenance, conversion, and abandonment work on oil, gas, injection, and geothermal wells…”. This rework is a cement squeeze of perforations, plug back, and reperforating and is considered maintenance of the well in order to ensure O&G production.

Exempt Status
Categorical Exemption
Type, Section or Code
Class 2: California Code of Regulations, title 14, section 15302
Reasons for Exemption
Class 2, Replacement or Reconstruction (14 CCR § 15302): It is also a potential Class 2 as this type of rework of a well is considered “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”.

Exempt Status
Categorical Exemption
Type, Section or Code
Class 4: California Code of Regulations, title 14, section 15304
Reasons for Exemption
Class 4, Minor Alterations to Land (14 CCR §§ 15304, 1684.2): It is also a possible Class 4. The project would be conducted entirely on an existing pad of greater than 0.5 acres (enough to contain all equipment). The project would not disturb any undisturbed areas. The project is located within an industrial area. Therefore, the project “consists of drilling operations that result in only minor alterations with negligible or no permanent effects to the existing condition of the land, water, air, and/or vegetation.” The rework would not expand the facility and is conducted in order to maintain level of service.
