The proposed project area consists of a fully operational active oil field named Mt Poso Oil Field (MPOF). The subject wells are among approximately 2,422 other wells within the MPOF. The subject property is located on a relatively hilly, open area in a dry region of the southern San Joaquin Valley. The topography of the area is typically comprised of low-lying hills, agricultural fields, and sparse vegetation, surrounded by fully industrial oil and gas development. 1.1.2 Work Proposal The primary work objective is to sidetrack five (5) existing well(s). This work is designed to support continuation of oil and gas resource development in the area. The wells are not being sidetracked (i) for abandonment purposes only or (ii) in connection with an enforcement order to mitigate or prevent environmental damage or surface expression. Sidetracking is the process of drilling a new wellbore from an existing wellbore. This is typically done when the original wellbore encounters a problem, when accessing remaining hydrocarbons within portions of the same reservoir, or when obstructions in the wellbore need to be bypassed. This process allows drilling a new section in an existing wellbore in the same rock formation restoring the well’s original functionality. The wells and their coordinates are listed in Table 2.

The entirety of this work would be located in an area of existing disturbance and no change in the surface topography (such as drainage patterns) would result. There will be no expansion of the existing well pads, roads, staging areas, or pipelines. No new grading would occur in any undisturbed areas. No new road construction or expansions would be required for the proposed project. Routine maintenance activities at the site would include removal of weeds and other ruderal vegetation for fire control and road maintenance. The following is a breakdown of anticipated disturbance by sidetrack operation in acres in Table 3 shown below. Well Name Bio Report Site Footprint Permanent Temporary Sensitive Needed? (ac.)

The time of year the work would occur is dependent on the date of final CalGEM permit approval. For a single well, it is expected to take approximately 17 operational days to complete all construction phases. Construction activities would generally include the following phases: 1. Partial abandonment of existing damaged wellbore • Zonal abandonment of well to be sidetracked in accordance with CalGEM abandonment requirements. 2. Site preparation • Site location work on existing well pads to create safe work site for personnel and environment. 3. Sidetrack drilling (construction) of the well • Sidetracking operations in accordance with CalGEM regulations 4. Well completion • Subsurface completion of well in accordance with CalGEM regulations 5. Final site surface construction • Re-installation of various aboveground piping and equipment to connect well sites to the existing infrastructure. The estimated duration of each phase per well can be found in Table 4.

No new ground disturbance would occur. The proposed construction activities would use existing electrical lines. The proposed construction activities would involve a combination of re-use, repair, or re-installation of various above-ground piping to connect subject well sites to the existing infrastructure. 1.2.3 Hazardous Waste Management All wastes would be profiled and any that are deemed hazardous would be handled and transported to an approved hazardous waste disposal facility. The proposed work is not expected to generate wastes that deviate from established waste profiles. Solid waste would be generated in a number of ways during routine well operations and maintenance and drilling of the well. During drilling, the major source of waste will be drill cuttings. All drilling cuttings would be disposed of in on-site sumps. The project would also be required to comply with Assembly Bill 1960 implementing regulations, which address Spill Contingency Plan requirements; oilfield sumps; production facilities containment, maintenance and testing, safety equipment and other equipment. A low solids non-dispersed mud system containing bentonite, water, non-hazardous polymer, and nonreactive lost circulation materials (e.g., sawdust, nut plug, and prima-seal) would be used in drilling operation. CRPC will comply with the General Order Notice of Applicability obtained from the Central Valley Regional Water Control Boards for boring wastes, consisting of drilling mud and drill cuttings, which will be disposed of in a surface impoundment (sump) adjacent to each well and not transported off-site. Some hazardous materials would be used and stored on site according to applicable federal, state and local regulations. However, the proposed sidetracks would not result in the production of hazardous waste as defined and regulated by Titles 22 and 23 of the California Code of Regulations. Rather, the proposed work would generate non-hazardous designated waste, including drilling mud and oily wastes that, if required, can be transported and disposed of at a permitted disposal facility. In the unlikely event that anticipated waste were to later be deemed a hazardous Class I waste by the state, such waste would be treated, stored and disposed of at an offsite facility permitted to accept Class I waste. Hazardous materials and non-hazardous waste would be transported by a licensed transportation company. 1.2.4 Personnel, Transportation, and Parking The increase in traffic associated with construction activities would be during the typical work hours Monday through Friday 6 am to 5 pm except during sidetrack drilling which is a 24-hour, 7-day-a-week operation. CRPC would use existing roads to access the project site. Deliveries of new drilling, maintenance, or other equipment, as well as the removal of old equipment, including drilling rigs, would utilize existing roadways. Traffic would avoid peak hours [and residential roadways] to the maximum extent feasible. [CRPC would not use residential roadways.] A journey management evaluation of the route would be conducted prior to the mobilization of the equipment. The speed limit while driving on unpaved roads would not exceed 10 miles per hour (mph), except as otherwise permitted by posted signs. Dust would be controlled via water trucks scheduled throughout the day, or by special request, consistent with CRPC’s Fugitive Dust Control Plan. Heavy equipment would remain on the work site or at the dedicated staging area(s) during the construction phase of the sidetrack operation. Daily changes in traffic patterns would be limited to the additional work crews travelling to and from the site during the work. All employee and truck parking would occur within the existing well pads or within other disturbed areas and employees would carpool to the well sites. Site access and parking at the well sites would not change as a result of the proposed sidetrack work. 1.3 Key Considerations Summary • Work locations will be accessed using existing access roads • No new road construction or improvement will be needed • The work will occur on existing well pads • All equipment will be staged within the project boundary on existing well pads and access roads • No new grading in undisturbed areas will occur in any phase of the work • The work will use existing electrical lines • The work will involve re-use, repair, or re-installation of various above-ground piping to connect well sites to existing infrastructure • No new infrastructure will occur as a result of the work • All waste from the project will be handled per state and county regulations • This work is designed to support continuation of resource development in the area. No additional facilities or equipment will be required beyond that described in this application • The zone of completion for the proposed sidetrack is a known hydrocarbon zone • The work will not change the zone of completion or pool of any wells • The work will not result in a change in purpose or capacity of any wells • The work will not result in in a change in well type of any wells • The proposed sidetrack is not for abandonment purposes only • The proposed sidetrack is not associated with a UGS Project • The work does not occur within an artificial island • The work will comply with updated CalGEM regulations • There are no sensitive receptors within the project area • There are no sensitive plant or wildlife species within the project area CHAPTER 2: ENVIRONMENTAL SETTING AND EXISTING CONDITIONS The project site is located within the Mount Poso Oilfield in unincorporated Kern County, in the San Joaquin Valley of California. The Mount Poso Oilfield is a designated CalGEM oilfield located north of the City of Bakersfield. The field parallels State Route 65. Access to the project site will be off Granite Road, a (Kern) County-maintained public road. Portions of the field are under the jurisdiction of the federal government (Bureau of Land Management). However, none of the proposed reworks have a federal component. The proposed sidetracks are located on existing, maintained well pads within the Mount Poso Oilfield. Reworked wells will tie into existing infrastructure. Existing operations are comprised of existing wells, single and multi-well pads and support oil and gas infrastructure, such as production pipelines, powerlines, access roads, production facilities and non-oil and gas facilities. The undisturbed areas within the Oilfield contain scattered areas of saltbush scrub and non-native grassland habitat. The rework activities will not require new disturbance. There are no incorporated cities within the Mt Poso field boundary, however, there are lands and minerals owned by the federal government that fall within the field. The oil produced in the Mount Poso Oilfield is heavy crude, extracted via primary and secondary recovery mechanisms. Active injection projects are carried out in compliance with applicable Underground Injection Control (UIC) permits or are in the permitting process. The site’s topography is typical of the region, and the surrounding land is densely developed for oil and gas extraction. All operations will take place on existing well pads, with no expansion requirements, resulting in no new disturbance (0.00 Ac). Grading and earthwork will be limited to these previously disturbed areas. No waterways, including ephemeral streams, are present within the site boundaries, and the site is not located within an alluvial drainage. Well construction standards ensure no impact on groundwater quality or supply. Crude oil and natural gas produced in the field are processed and transported to local markets via established infrastructure. Natural gas is either consumed in operations, sold into the California market, re-injected, or repurposed for fuel gas and steam generation. Power for field operations is supplied by in-field power generation equipment or external sources. Adjacent areas may support special-status species, but no significant ecological disturbances are anticipated as operations will remain confined to the previously developed areas. The proposed project consists of the California Department of Conservation, Geologic Energy Management Division (CalGEM) approving 5 permit(s) for California Resources Production Corporation to rework the well(s) listed below, in the Mount Poso Oil Field, to address well integrity issues.
