The supervisor shall determine the amount of the security required of each operator, based on his or her determination of the reasonable costs of that plugging and abandonment, after providing the operator with an opportunity to submit a cost estimate for consideration by the supervisor. The supervisor may not adjust the amount of security required of each operator more frequently than once every three years, to reflect changes in those costs. An operator may self-insure this security obligation if the supervisor, at his or her discretion, determines that the operator has sufficient financial resources to plug and abandon the wells for which the operator is responsible. The security shall remain in effect until all wells are plugged and abandoned in accordance with Section 3208, but the supervisor shall reduce the amount of the security required of an operator to reflect reduced obligations as wells are plugged and abandoned. (c) If the state lease or other agreement that sets forth obligations or performance requirements under the lease provides security that is equal to, or greater than, the total of the additional security required pursuant to subdivision (b), plus all other liabilities under the lease or other agreement, the supervisor shall not require the additional security.

Cal. Public Resources Code - PRC § 3205.2. Section 3205.2.

(a) Notwithstanding Section 3204, any person who engages in the operation of a class II commercial wastewater disposal well, as defined in subdivision (d), shall file an indemnity bond with the supervisor for one hundred thousand dollars ($100,000) for each well so used.

The bond shall be executed by the person as the principal, and by an authorized surety company as the surety, and, except for differences in the amount, shall be in substantially the same language and upon the same conditions as provided in Section 3204. (b) A blanket bond submitted under subdivision (a) of Section 3205 may be used in lieu of the bond required in subdivision (a), except that the termination and cancellation shall be in accordance with subdivision (c) of this section. (c) Notwithstanding Section 3207, any bond issued in compliance with this section may be terminated and canceled and the surety relieved of all obligations thereunder when the well is properly abandoned or another valid bond has been substituted therefor. (d) A class II commercial wastewater disposal well is a well that is used to dispose of oilfield wastewater for a fee and that is regulated by the division pursuant to this chapter and Subpart F (commencing with Section 147.250) of Part 147 of Title 40 of the Code of Federal Regulations.

Cal. Public Resources Code - PRC § 3205.3. Section 3205.3.

(a) The division may require an operator filing an individual indemnity bond pursuant to Section 3204 or a blanket indemnity bond pursuant to Section 3205, as applicable, to provide an additional amount of security acceptable to the division based on the division’s evaluation of the risk that the operator will desert its well or wells and the potential threats the operator’s well or wells pose to life, health, property, and natural resources. The additional security required by the division shall not exceed the lesser of the division’s estimation of the reasonable costs of properly plugging and abandoning all of the operator’s wells and decommissioning any attendant production facilities in accordance with Section 3208, or thirty million dollars ($30,000,000). (b) When making an estimation under this section of the reasonable costs of properly plugging and abandoning an operator’s well or wells and decommissioning any attendant production facilities, the division shall provide the operator with an opportunity to submit the operator’s own estimation and shall consider all of the following: (1) The depth of the well or wells. (2) The accessibility and surroundings of the well or wells and any attendant production facilities. (3) Available information about the condition of the well or wells and any attendant production facilities. (4) Available information about the cost to plug and abandon a comparable well or wells. (5) Available information about the cost to decommission production facilities comparable to the production facilities attendant to the well or wells. (6) The operator’s cost estimates, if provided. (7) Whether the operator is a public utility gas corporation, as defined in subdivision (a) of Section 216 of the Public Utilities Code. (8) Any other information that the division determines to be relevant to the estimation of cost. (c) The division, in evaluating the risk that the operator will desert its well or wells and the potential threats the operator’s well or wells pose to life, health, property, and natural resources, shall consider all of the following: (1) The difference between the estimation of reasonable costs of plugging and abandonment under subdivisions (a) and (b) and the total amount of indemnity bonds or other financial assurances in place to ensure funding of the plugging and abandonment of the operator’s well or wells. (2) The level of current production from the well or wells. (3) Available information regarding estimated reserves remaining in place associated with the well or wells. (4) Whether the well or wells are “critical,” are “environmentally sensitive,” or are in an “urban area,” as those terms are defined by the division in regulation. (5) To the extent that relevant information is available to the division, the financial status of the operator and the operator’s financial capacity to plug and abandon all of the operator’s wells. (6) The past record of compliance by the operator with the division. (7) The number of idle wells to be covered by the indemnity bond and the operator’s record of compliance with the requirements of Section 3206 and the division’s regulations related to the management of idle wells. (8) Whether the operator’s well or wells are subject to any bonding or financial assurance requirements by a local government. (9) Whether the operator’s well or wells are already subject to additional bond coverage by the division pursuant to Section 3270.4. (10) Any other information that the division determines to be relevant to the evaluation of the risk. (d) The division shall provide the operator with notice of the requirement to provide additional security, and the notice shall be served by personal service or certified mail. The operator shall provide the additional security within 180 days of service of notice. The notice shall include an explanation of the division’s estimation of the reasonable costs to plug and abandon the operator’s well or wells and of the basis for the decision to require the operator to provide additional security. The requirements of this subdivision shall also apply to any subsequent increase in the amount of additional security required under subdivision (e). (e) The division shall increase or decrease the amount of additional security required under this section to account for changed circumstances or new information. The operator may, at any time, petition the division to reevaluate the division’s evaluation of the risk or cost estimates, and the division shall respond to the petition in writing within 60 days of receipt of the petition. (f) (1) An operator shall provide additional security required under this section in the form of an indemnity bond, a form of deposit described in Section 995.710 of the Code of Civil Procedure, or any other equally effective means of financial assurance approved by the division. Examples of equally effective means of financial assurance that the division may consider for approval include a letter of credit, a corporate guarantee, a trust fund, or a demonstration of self-insurance. (2) The division may only approve self-insurance as an equally effective means of financial assurance if the operator provides detailed financial information demonstrating to the division’s satisfaction that, based on the considerations under subdivision (c), the risks associated with the operator’s potential for desertion of its well or wells are low. If the division approves self-insurance as an equally effective means of financial assurance, at least once every five years the operator shall update the supporting financial information and the division shall reevaluate whether self-insurance continues to be an equally effective means of financial assurance. If an operator provides financial information to the division under this section that is not otherwise publicly available, the division shall maintain the information as confidential. (g) (1) Any two or more operators may elect to enter into a liability sharing agreement. (2) Operators that elect to participate in a liability sharing agreement shall be jointly and severally liable for all amounts owed under this chapter by all other operators that participate in the liability sharing agreement. (3) The division shall treat all operators that participate in a liability sharing agreement as a single operator when requiring additional security under this section, except that the additional security required by the division shall not exceed the lesser of the division’s estimation of the reasonable costs of plugging and abandoning all of the participating operators’ wells and decommissioning any attendant production facilities in accordance with Section 3208, or thirty million dollars ($30,000,000). (4) A liability sharing agreement is formed when all of the participants have provided the division written notice of intent to participate in the liability sharing agreement with express acknowledgment of all other participants in the agreement. (5) An operator may elect to withdraw from a liability sharing agreement at any time, but all participants in the liability sharing agreement, including the withdrawing participant, shall continue to be jointly and severally liable for all amounts owed under this chapter for a period of five years after the withdrawal.

(2) Exclude from each initial report due on or before July 1, 2026, all offshore wells and facilities of the operator evaluated pursuant to Section 3205.6. Include in each followup report due after July 1, 2026, all offshore wells and facilities of the operator. (d) If the supervisor determines that the operator has failed to use the requisite criteria or has otherwise provided estimates in the report that are neither credible nor accurate, the supervisor may request the operator to submit revised estimates for review and approval on a timely schedule to be determined by the supervisor. Failure to comply with this requirement or a request pursuant to this section is a violation of this chapter and is subject to any penalty provided by law, including, but not limited to, Sections 3236 and 3236.5.

Cal. Public Resources Code - PRC § 3205.8. Section 3205.8.

(a) (1) Notwithstanding any other provision of this chapter, a person who acquires the right to operate a well or production facility, by purchase, transfer, assignment, conveyance, exchange, or other disposition, except a well that has an average daily production level that exceeds 15 barrels of oil or 60,000 cubic feet of natural gas during the 12 months preceding the date of acquisition or a natural gas storage well, shall, as soon as possible, but not later than the date when the acquisition of the well or production facility becomes final, file with the supervisor an individual indemnity bond for the well or production facility, or a blanket indemnity bond for multiple wells or production facilities, in an amount determined by the supervisor to be sufficient to cover, in full, all costs of plugging and abandonment, decommissioning of the facility, and site restoration pursuant to Section 3208 and regulations implementing this chapter. (2) A person who acquires the right to operate more than one well or production facility, by purchase, transfer, assignment, conveyance, exchange, or other disposition, or who operates more than one well or production facility may file with the supervisor one blanket indemnity bond to cover all the operations in any of its wells in the state in lieu of an individual indemnity bond for each operation. The blanket indemnity bond shall be executed by the operator, as principal, and by an authorized surety company, as surety, and shall be in substantially the same language and upon the same conditions as provided in Section 3204, except for the difference in the amount. (b) A person who intends to acquire the right to operate a well or production facility, by purchase, transfer, assignment, conveyance, exchange, or other disposition, shall submit a request to the supervisor for a determination of the amount of the bond required pursuant to subdivision (a) before completing the acquisition and shall not complete the acquisition until the determination is received and the bond has been filed with the supervisor. (c) The supervisor shall determine the amount of an individual indemnity bond required pursuant to subdivision (a) based on the supervisor’s determination of the full costs of plugging and abandonment, decommissioning the facility, and site restoration using any reasonable method, including, but not limited to, consideration of the factors listed in subdivision (b) of Section 3205.3, or the cost estimation criteria described in subdivision (b) of Section 3205.7, or consultation with a contractor to obtain an estimate of the cost to plug and abandon the wells, decommission the facility, and complete site restoration. The supervisor shall determine the amount of a blanket indemnity bond required pursuant to subdivision (a) based on the sum total of combining the costs from the same determinations as individual indemnity bonds for each well or production facility covered by the blanket indemnity bond. (d) In lieu of the bond required to be provided pursuant to subdivision (a), the operator may, with the written approval of the supervisor, provide the required security through an equally effective means of financial assurance, which includes a deposit pursuant to Section 3205.5, an irrevocable letter of credit, or a fully funded trust fund, but does not include self-insurance or corporate guarantees.

(2) File a plan with the supervisor to provide for the management and elimination of all idle wells. For purposes of the plan, elimination of an idle well shall be accomplished when the well has been properly abandoned in accordance with Section 3208, or it has been shown to the division’s satisfaction that, since the well became an idle well, the well has maintained production of oil or gas, maintained production of water used in production stimulation, or been used for enhanced oil recovery, reservoir pressure management, or injection for a continuous six-month period. The plan shall comply with all of the following: (A) Specify the calendar year or years that it covers. The plan and any renewal of the plan shall cover a time period of up to eight years. (B) Require the operator to consider all of the following when prioritizing idle wells for plugging and abandonment, in addition to priorities identified by the supervisor in regulations: (i) The age of the idle well. (ii) Any indication that the idle well potentially poses a threat to life, health, property, or natural resources. (iii) Wells that are located within 3,200 feet of a sensitive receptor, as defined in Section 3280. (C) Include notes indicating the basis for prioritizing wells. (D) Be subject to approval by the supervisor, who may prioritize the order in which idle wells are addressed. (E) Be reviewed for performance annually by the supervisor, and be subject to amendment by the supervisor, or by the operator with the approval of the supervisor. An updated plan shall be required if there is a change in ownership or holdings of the operator. (F) The required rate of idle well elimination shall be based upon the number of idle wells under the control of an operator on January 1 of each year, as specified in subparagraph (G). If the operator has eliminated more wells than required in calendar year 2024 or any subsequent calendar year, the supervisor may deduct from the new requirement the number of idle wells eliminated in excess of those previously required. In addition, the supervisor may require additional well testing requirements as part of the plan. (G) (i) For calendar years 2025 to 2027, inclusive, unless and until the operator has no idle wells, require that operators with 250 or fewer idle wells eliminate at least 5 percent of their idle wells each year, and, in no case, less than 1 idle well; operators with 251 to 1,250, inclusive, idle wells eliminate at least 6 percent of their idle wells each year; operators with 1,251 to 3,000, inclusive, idle wells eliminate at least 7 percent of their idle wells each year; and operators with more than 3,000 idle wells eliminate at least 15 percent of their idle wells each year. (ii) For calendar years 2028 and 2029, unless and until the operator has no idle wells, require that operators with 250 or fewer idle wells eliminate at least 6 percent of their idle wells each year, and, in no case, less than 1 idle well; operators with 251 to 1,250, inclusive, idle wells eliminate at least 8 percent of their idle wells each year; operators with 1,251 to 3,000, inclusive, idle wells eliminate at least 10 percent of their idle wells each year; and operators with more than 3,000 idle wells eliminate at least 18 percent of their idle wells each year. (iii) For calendar year 2030 and all subsequent calendar years, unless and until the operator has no idle wells, require that operators with 250 or fewer idle wells eliminate at least 8 percent of their idle wells each year, and, in no case, less than 1 idle well; operators with 251 to 1,250, inclusive, idle wells eliminate at least 10 percent of their idle wells each year; operators with 1,251 to 3,000, inclusive, idle wells eliminate at least 15 percent of their idle wells each year; and operators with more than 3,000 idle wells eliminate at least 20 percent of their idle wells each year. (H) An operator who fails to comply with the plan, as determined by the supervisor after the annual performance review, is not eligible to use the requirements of this paragraph, for purposes of compliance with this section, for any of its idle wells. An operator may appeal to the director pursuant to Article 6 (commencing with Section 3350) regarding the supervisor’s rejection of a plan and plan amendments and the supervisor’s determination of the operator’s failure to comply with a plan. If the supervisor’s determination that the operator failed to comply with the plan is not timely appealed, or if the director upholds the supervisor’s determination upon appeal, the operator shall immediately file the fees required under paragraph (1) for each year that the operator failed to comply with the plan. That operator may not propose a new idle well plan under this paragraph for the next two years and then only if the operator has paid all required idle well fees and any associated late payment penalties and interest. (b) All fees received under this section shall be deposited in the Hazardous and Idle-Deserted Well Abatement Fund, which is hereby created in the State Treasury. Notwithstanding Section 13340 of the Government Code, the moneys in the Hazardous and Idle-Deserted Well Abatement Fund are hereby continuously appropriated to the department for expenditure without regard to fiscal year, to mitigate a hazardous or potentially hazardous condition, by well plugging and abandonment, decommissioning the production facilities, or both, at a well of an operator subject to the requirements of this section. (c) The failure to file, for any well, the fee required under this section shall be conclusive evidence of desertion of the well, permitting the supervisor to order the well abandoned pursuant to Section 3237. (d) This section does not prohibit a local agency from collecting a fee for regulation of wells. (e) Subject to the approval of the division, an idle well shall not be subject to the requirements of this section if the operator has made a diligent effort to locate and access the well, and provided documentation of those efforts demonstrating that it is infeasible to locate or physically access the wellbore. (f) This section does not apply to an idle well that is the subject of a court-approved settlement agreement entered into on or before December 31, 2024, between a local governmental entity and the operator of the idle well, if that settlement agreement imposes more stringent requirements relating to the management and elimination of idle wells than the requirements imposed by the amendments to this section made by Assembly Bill 1866 of the 2023–24 Regular Session of the Legislature.

Cal. Public Resources Code - PRC § 3206.1. Section 3206.1.

(a) By June 1, 2018, the division shall review, evaluate, and update its regulations pertaining to idle wells. The update shall include idle well testing and management requirements that, at a minimum, include all of the following: (1) Appropriate testing, as determined by the supervisor, to determine whether the fluid level is above the base of an underground source of drinking water. (2) Appropriate testing, as determined by the supervisor, to verify the mechanical integrity of the well. (3) Appropriate remediation, as determined by the supervisor, of idle wells if there is an indication of a lack of mechanical integrity. (4) For a well that has been an idle well for 15 years or more, an engineering analysis demonstrating to the division’s satisfaction that it is viable to return the idle well to operation in the future. (b) If the operator demonstrates to the division’s satisfaction that the well is not within one-half mile of an underground source of drinking water, testing required under the regulations implementing this section shall not be required until at least two years after the well becomes an idle well. This subdivision shall not be construed to prohibit or limit any other testing required under this chapter. (c) At the discretion of the supervisor, the regulations implementing this section may provide an option for temporary or partial well abandonment in lieu of compliance with the requirements of the regulations implementing this section. (d) If the operator does not remediate an idle well as required by the regulations implementing this section, or the operator does not demonstrate that an idle well is economically viable as required by the regulations implementing this section, then the operator shall plug and abandon the idle well in accordance with Section 3208. (e) Failure to file to comply with the requirements of the regulations implementing this section shall be conclusive evidence of desertion of the well, permitting the supervisor to order the well abandoned pursuant to Section 3237. (f) For purposes of this section, an “underground source of drinking water” has the same meaning as in the federal Safe Drinking Water Act (42 U.S.C. Sec. 300f).

(B) The supervisor shall not charge an administrative penalty pursuant to subparagraph (A) for a violation by a well owner if the supervisor has already charged an administrative penalty to that well owner for a violation, applicable to the same well and covering the same time period, pursuant to subdivision (d).

Cal. Public Resources Code - PRC § 3206.2. Section 3206.2.

(a) (1) The division, in consultation with the State Air Resources Board, shall initiate a study to be conducted by independent experts of fugitive emissions from idle, idle-deserted, and abandoned wells in the state. The independent experts selected shall have experience measuring and documenting emissions from multiple idle and abandoned wells and well sites, preferably at multiple locations within the state. (2) In developing the parameters of the study, the division shall seek input from researchers with expertise in fugitive emissions, oil and gas operators, and people with relevant experience in nongovernmental organizations. The parameters of the study shall (A) be conducted based on a total well sample not to exceed 500 wells, (B) utilize existing information and technology tools that allow data collection without disruption to a well site, (C) limit surface disturbance associated with any emissions sampling, and (D) limit the total cost of the study to a maximum of one million dollars ($1,000,000). (3) In implementing the study, the division shall seek to minimize costs to operators, and the testing conducted pursuant to this section shall not conflict with a scheduled routine maintenance operation of the well or associated equipment. (4) The study shall be conducted to measure emissions of air pollutants, including, but not limited to, greenhouse gases, toxic air contaminants, and volatile organic compounds, from idle wells, idle-deserted wells, and abandoned wells that can contribute to climate change or endanger occupational and public health and safety through their toxicological properties. (5) The division shall work with the independent experts, oil and gas operators, and nongovernmental organizations to identify a stratified random sample of wells, and set of pollutants to be measured, from which measurement data can be used to extrapolate to the total number of idle, idle-deserted, and abandoned wells in the state. To the maximum extent possible, the sample shall include emissions data already collected from wells in the state. (6) The sample of wells shall include idle-deserted wells identified by the division, previously abandoned wells, and idle wells that are ordered or permitted to be plugged and abandoned by the division. (7) For purposes of undertaking the study, for a well that is selected for measurement as part of the sample but which is also scheduled to be plugged, abandoned, or reabandoned, before the initiation of physical work to plug, abandon, or reabandon the well the division or the contracted independent experts, with oversight from the division, shall have testing performed for leaks on the well and associated equipment either (A) in accordance with the United States Environmental Protection Agency Reference Method 21, as set forth in Appendix A-7 to Part 60 of Title 40 of the Code of Federal Regulations, as it read on January 1, 2019, (B) by using an optical gas imaging instrument that is operated by a technician with a certification or training in infrared theory, infrared inspections, and heat transfer principles, or (C) in accordance with an alternative methodology developed for the purposes of this study. (8) If, pursuant to paragraph (7), a well is found to emit hydrocarbons in observable quantities using an optical imaging device or in concentrations greater than 1 percent by volume using a United States Environmental Protection Agency Reference Method 21 instrument when tested before the initiation of physical work, the division or the contracted independent experts shall ensure additional testing is performed using a direct measurement method consisting of high volume sampling, bagging, or a calibrated flow measuring instrument to determine the flow rate of atmospheric emissions of total and speciated hydrocarbon pollutants before the initiation of physical work. (b) Oil and gas operators with wells selected for purposes of sampling under this section shall make reasonable efforts to permit access to the wells to the division and the independent experts contracted to undertake the study if adequate notice is provided to the operator to ensure appropriate safety precautions are taken at the well site. All oil and gas operators with wells selected for sampling shall submit to the division a certification stating that no action was taken to reduce emissions from the sampling site within 72 hours of the sampling taking place so as to reduce the value of measurements taken. (c) On or before January 1, 2026, the department shall post all results of testing conducted pursuant to subdivision (a) on the department’s internet website in a machine-readable format. On or before January 1, 2021, the department shall produce and post to the department’s internet website an interim progress report describing the status of the study conducted pursuant to this section, including, but not limited to, the number of wells where testing has been completed, the number of wells remaining to be tested, study costs, and any preliminary testing results, as available and subject to the requirement described in paragraph (2) of subdivision (d). (d) (1) On or before July 1, 2026, the independent experts contracted to undertake the study shall complete a written document that includes an executive summary of the findings, a description of the results, the findings, and an estimate of hydrocarbon emissions from the state’s idle, idle-deserted, and abandoned wells. (2) Before public release pursuant to subdivision (e), the written document shall be provided for peer review and comments, to the operators whose wells were included in the sample, and to a group of independent experts and nongovernmental organizations selected by the division. (e) On or before January 1, 2028, the division shall make the results of the study, as per the written document required pursuant to subdivision (d), available on its internet website. (f) This section shall remain in effect only until January 1, 2029, and as of that date is repealed.

Cal. Public Resources Code - PRC § 3206.3. Section 3206.3.

(a) (1) Notwithstanding Section 10231.5 of the Government Code, on or before July 1, 2019, and annually thereafter, the supervisor shall, in compliance with Section 9795 of the Government Code, prepare and transmit to the Legislature a comprehensive report on the status of idle and long-term idle wells for the preceding calendar year. The report shall include all of the following: (A) A list of all idle and long-term idle wells in the state by American Petroleum Institute identification number and indicating the operator, field, and pool.

(C) A list of orphan wells remaining, the estimated costs of abandoning those orphan wells, and a timeline for future orphan well abandonment with a specific schedule of goals. Idle and long-term idle wells that have become orphan wells shall be identified in the list. For the purposes of this report, an orphan well is a well that has no party responsible for it, leaving the state to plug and abandon it. (D) A list of all operators with plans filed with the supervisor for the management and elimination of all long-term idle wells and the status of those plans. (E) A list of all wells for which the division has approved a demonstration of inaccessibility under subdivision (e) of Section 3206. (F) Any additional relevant information as determined by the supervisor. (2) The report shall be made publicly available and an electronic version shall be available on the division’s internet website. (b) For the report due on or before July 1, 2022, and each report thereafter, the division shall do both of the following: (1) Conduct inspections of production facilities attendant to long-term idle wells to ensure compliance with the requirements of this chapter. Information summarizing violations and pertinent findings in these inspections shall be included in the applicable report required to be prepared and transmitted pursuant to subdivision (a). (2) Identify idle wells by the American Petroleum Institute identification number that are registered to an operator and that have met the definition of an idle well for three years where neither the required annual fee has been paid or the well is part of a valid idle well management plan on file with the supervisor pursuant to subdivision (a) of Section 3206. (c) For the report due on or before July 1, 2023, and each report thereafter, the division shall provide a description of activities undertaken by the division’s collections unit established pursuant to Section 3243. This description shall include the number of operators and amounts of idle well fees collected by the collections unit in the preceding year, the criteria, including timelines, used by the collections unit to determine a well or attendant facility is deserted, and the amount of costs recovered from operators or responsible parties for work ordered by the supervisor or undertaken by the division. Information related to the division’s use of liens, including, but not limited to, the number of wells and facilities eligible to be subject to a lien, the number of liens placed by the supervisor, and the number of liens released by the supervisor, shall also be provided. (d) Information on how to access the plans described in subparagraph (D) of paragraph (1) of subdivision (a) shall be made readily available on the division’s internet website. (e) The division shall continue to regularly provide updated information describing idle and long-term idle wells on the division’s internet website.

Cal. Public Resources Code - PRC § 3206.5. Section 3206.5.

(a) Any city or county may request from the supervisor a list of all idle wells, as defined in subdivision (d) of Section 3008, within its jurisdiction. (b) After receiving the list from the supervisor, the city or county may identify idle wells identified pursuant to subdivision (a) within its jurisdiction which it has determined, based on a competent, professional evaluation, have no reasonable expectation of being reactivated, and formally request the supervisor to make a determination whether the wells should be plugged and abandoned. (c) Upon receiving the written request of a city or county, as specified in subdivision (b): (1) The supervisor may, within 60 days of receiving a written request from a city or county, require the operator or operators to file a statement for each well outlining those reasons why the wells should not be plugged and abandoned. (2) The supervisor shall, within 120 days of receiving a written request, make a determination as to whether any of these wells should be plugged and abandoned, pursuant to the criteria contained in this chapter. (d) Failure of the operator to file, for any well, the statement required under this section shall be conclusive evidence of desertion of the well, thereby permitting the supervisor to order the well abandoned.

Cal. Public Resources Code - PRC § 3207. Section 3207.

(a) Any individual or blanket indemnity bond issued in compliance with this chapter may be terminated and canceled and the surety relieved of all obligations thereunder when the well or wells covered by such bond have been properly abandoned pursuant to Section 3208, or another valid bond has been substituted therefor. Should the person who has filed a blanket bond properly abandon a portion of his or her wells covered by the bond, the bond may be terminated and canceled and the surety relieved of all obligations thereunder upon the filing by such person of an individual bond for each well that is still not abandoned. Liability as to individual wells that have been properly abandoned under a blanket bond may also be terminated. (b) This section shall become operative on January 1, 2018.

Cal. Public Resources Code - PRC § 3208. Section 3208.

(a) For the purposes of Sections 3206 and 3207, a well is properly abandoned when it has been shown, to the satisfaction of the supervisor, that all proper steps have been taken to isolate all oil-bearing or gas-bearing strata encountered in the well, and to protect underground or surface water suitable for irrigation or farm or domestic purposes from the infiltration or addition of any detrimental substance and to prevent subsequent damage to life, health, property, and other resources. For purposes of this subdivision, proper steps include the plugging of the well, decommissioning the attendant production facilities of the well, or both, if determined necessary by the supervisor. (b) This section shall become operative on January 1, 2018.

Cal. Public Resources Code - PRC § 3208.1. Section 3208.1.

(a) To prevent, as far as possible, damage to life, health, and property, the supervisor or district deputy may order, or permit, the reabandonment of any previously abandoned well if the supervisor or the district deputy has reason to question the integrity of the previous abandonment, or if the well is not accessible or visible. (b) The operator responsible for plugging and abandoning deserted wells under Section 3237 shall be responsible for the reabandonment except in the following situations: (1) The supervisor finds that the operator plugged and abandoned the well in conformity with the requirements of this division in effect at the time of the plugging and abandonment and that the well in its current condition presents no immediate danger to life, health, and property but requires additional work solely because the owner of the property on which the well is located proposes construction on the property that would prevent or impede access to the well for purposes of remedying a currently perceived future problem. In this situation, the owner of the property on which the well is located shall obtain all rights necessary to reabandon the well and be responsible for the reabandonment. (2) The supervisor finds that the operator plugged and abandoned the well in conformity with the requirements of this division in effect at the time of the plugging and abandonment and that construction over or near the well preventing or impeding access to it was begun on or after January 1, 1988, and the property owner, developer, or local agency permitting the construction failed either to obtain an opinion from the supervisor or district deputy as to whether the previously abandoned well is required to be reabandoned or to follow the advice of the supervisor or district deputy not to undertake the construction. In this situation, the person or entity causing the construction over or near the well shall be responsible for the reabandonment. (3) The supervisor finds that the operator plugged and abandoned the well in conformity with the requirements of this division in effect at the time of the plugging and abandonment and after that time someone other than the operator or an affiliate of the operator disturbed the integrity of the abandonment in the course of developing the property, and the supervisor is able to determine based on credible evidence, including circumstantial evidence, the party or parties responsible for disturbing the integrity of the abandonment. In this situation, the party or parties responsible for disturbing the integrity of the abandonment shall be responsible for the reabandonment. (c) For purposes of this section, being responsible for the reabandonment means that the responsible party or parties shall complete the reabandonment and be subject to the requirements of this chapter as an operator of the well. The responsible party or parties shall file with the supervisor the appropriate bond or security in an amount specified in Section 3204, 3205, or 3205.1. If the reabandonment is not completed, the supervisor may act under Section 3226 to complete the work. (d) Except for the situations listed in paragraphs (1), (2), and (3) of subdivision (b), nothing in this section precludes the application of Article 4.2 (commencing with Section 3250) when its application would be appropriate.

Cal. Public Resources Code - PRC § 3209. Section 3209.

The provisions of Section 3207 as to termination and cancellation shall also apply to all bonds which have been heretofore filed with the supervisor as then provided by law.

Cal. Public Resources Code - PRC § 3210. Section 3210.

(ii) A knowing, willful, or intentional violation. (iii) A chronic violation or one that is committed by a recalcitrant violator. In determining whether a violation is chronic or a violator is recalcitrant, the supervisor shall consider whether there is evidence indicating that the violator has engaged in a pattern of neglect or disregard with respect to applicable requirements. (B) The administrative civil penalty amount for a major violation shall be not less than two thousand five hundred dollars ($2,500) per violation and not more than twenty-five thousand dollars ($25,000) per violation. (3) (A) For purposes of this section, a “minor violation” is a violation that is neither a well stimulation violation nor a major violation. (B) The administrative civil penalty amount for a minor violation shall be not more than two thousand five hundred dollars ($2,500) per violation. (4) At the supervisor’s discretion, each day a major or minor violation continues or is not cured may be treated as a separate violation. (c) An order of the supervisor imposing an administrative civil penalty shall be reviewable pursuant to Article 6 (commencing with Section 3350). When the order of the supervisor has become final and the penalty has not been paid, the supervisor may apply to the appropriate superior court for an order directing payment of the administrative civil penalty. The supervisor may also seek from the court an order directing that production from the well or use of the production facility that is the subject of the administrative civil penalty order be discontinued until the violation has been remedied to the satisfaction of the supervisor and the administrative civil penalty has been paid. (d) (1) The supervisor may allow a supplemental environmental project in lieu of a portion of the administrative civil penalty amount. The supplemental environmental project may not be more than 50 percent of the total administrative civil penalty amount. Any amount collected under this section that is not allocated for a supplemental environmental project shall be deposited in the Oil and Gas Environmental Remediation Account, established pursuant to Section 3261. (2) For purposes of this section, “supplemental environmental project” means an environmentally beneficial project that a person, subject to an order of the supervisor imposing an administrative civil penalty, voluntarily agrees to undertake in settlement of the action and to offset a portion of an administrative civil penalty. (e) (1) The supervisor may establish regulations prescribing specific penalty amounts for specific violations. (2) These regulations shall include a determination of whether the violation in question is a minor violation, a major violation, or a well stimulation violation. (3) Penalty amounts prescribed in regulation shall not exceed the maximum civil penalty amount for the type of violation and shall not be less than the minimum penalty amount for the type of violation. (4) When prescribing an administrative civil penalty amount by regulation, the supervisor shall consider the potential harm caused by the violation, the potential benefit to the violator resulting from the violation, the supervisor’s potential prosecution costs, and other relevant circumstances associated with enforcement of the requirement. When imposing an administrative civil penalty amount prescribed in regulation, the supervisor is not required to consider circumstances listed in subdivision (a). (f) The supervisor shall adjust the maximum penalties specified in this section for inflation based on the California Consumer Price Index. The adjustment shall be exempt from the Administrative Procedure Act (Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3 of Title 2 of the Government Code).

Cal. Public Resources Code - PRC § 3236.6. Section 3236.6.

The supervisor, or the supervisor’s designee, may recover from the owner or operator all response, prosecution, and enforcement costs incurred by the division arising from the administration and enforcement of this chapter. The supervisor may request, and a public prosecutor, the Attorney General, or an attorney for the division or department as part of a prosecution or negotiation, may allege a claim for, these costs and expenditures and shall deposit any recoveries into the Oil and Gas Environmental Remediation Account established pursuant to Section 3261.

Cal. Public Resources Code - PRC § 3237. Section 3237.

(a) (1) The supervisor or district deputy may order the plugging and abandonment of a well or the decommissioning of a production facility that has been deserted whether or not any damage is occurring or threatened by reason of that deserted well or production facility. The supervisor or district deputy shall determine from credible evidence whether a well or production facility is deserted. (2) For purposes of paragraph (1), “credible evidence” includes, but is not limited to, the operational history of the well or production facility, the response or lack of response of the operator to inquiries and requests from the supervisor or district deputy, the extent of compliance by the operator with the requirements of this chapter, and other actions of the operator with regard to the well or production facility. (3) A rebuttable presumption of desertion arises in any of the following situations: (A) If a well has not been completed to production or injection and drilling machinery have been removed from the well site for at least six months. (B) If a well’s production facilities or injection equipment has been removed from the well site for at least two years. (C) If an operator has failed to comply with an order of the supervisor within the time provided by the order or has failed to challenge the order on a timely basis. (D) If an operator fails to designate an agent as required by Section 3200. (E) If a person who is to acquire a well or production facility that is subject to a purchase, transfer, assignment, conveyance, exchange, or other disposition fails to comply with Section 3202. (F) If an operator has failed to maintain the access road to a well or production facility site passable to oilfield and emergency vehicles. (4) The operator may rebut the presumptions of desertion set forth in paragraph (3) by demonstrating with credible evidence compliance with this division and that the well or production facility has the potential for commercial production, including specific and detailed plans for future operations, and by providing a reasonable timetable for putting those plans into effect. The operator may rebut the presumption set forth in subparagraph (F) of paragraph (3) by repairing the access road. (b) An order to plug and abandon a deserted well or to decommission a production facility may be appealed to the director pursuant to the procedures specified in Article 6 (commencing with Section 3350). (c) (1) The current operator, as determined by the records of the supervisor, of a deserted well that produced oil, gas, or other hydrocarbons or was used for injection is responsible for the proper plugging and abandonment of the well or the decommissioning of deserted production facilities. If the supervisor determines that the current operator does not have the financial resources to fully cover the cost of plugging and abandoning the well or the decommissioning of deserted production facilities, the immediately preceding operator shall be responsible for the cost of plugging and abandoning the well or the decommissioning of deserted production facilities. (2) The supervisor may continue to look seriatim to previous operators until an operator is found that the supervisor determines has the financial resources to cover the cost of plugging and abandoning the well or decommissioning deserted production facilities. However, the supervisor may not hold an operator responsible that made a valid transfer of ownership of the well before January 1, 1996. (3) For purposes of this subdivision, “operator” includes a mineral interest owner who shall be held jointly liable for the well and attendant production facilities if the mineral interest owner has or had leased or otherwise conveyed the working interest in the well to another person, if in the lease or other conveyance, the mineral interest owner retained a right to control the well operations that exceeds the scope of an interest customarily reserved in a lease or other conveyance in the event of a default. (4) No prior operator is liable for any of the costs of plugging and abandoning a well or decommissioning deserted production facilities by a subsequent operator if those costs are necessitated by the subsequent operator’s illegal operation of a well or production facility. (5) If the supervisor is unable to determine that an operator who acquired ownership of a well after January 1, 1996, has the financial resources to fully cover the costs of plugging and abandonment of the well or decommissioning deserted production facilities, the supervisor may undertake plugging and abandonment of the well or decommissioning deserted production facilities pursuant to Article 4.2 (commencing with Section 3250). (6) By July 1, 2022, the supervisor shall provide to the Senate Committee on Natural Resources and Water and the Assembly Committee on Natural Resources the process the supervisor has established to determine that the current operator does not have the financial resources to fully cover the cost of plugging and abandoning the well or the decommissioning of deserted production facilities pursuant to paragraph (1), or for a previous operator pursuant to paragraphs (1) and (2). The supervisor shall, in a timely manner, post the materials provided to the legislative committees pursuant to this paragraph on a public portion of the division’s internet website. (d) (1) Notwithstanding any other provision of this chapter, the supervisor or district deputy, at the supervisor’s or district deputy’s sole discretion, may determine that a well that has been idle for 25 years or more and that fails to meet either of the following conditions is conclusive evidence of desertion, and may order the well abandoned: (A) The operator is operating in compliance with a valid idle well management plan that is on file with the supervisor pursuant to paragraph (2) of subdivision (a) of Section 3206 or is covered by an indemnity bond provided under Section 3204, subdivision (a) of Section 3205, or subdivision (a) of Section 3205.2. (B) The well meets the relevant testing standards for idle wells required under the regulations implementing this chapter. (2) The supervisor or district deputy shall provide the operator a 90-day notice of warning once a determination has been reached pursuant to this subdivision that a well has been deserted. An operator may rebut the determination, made pursuant to paragraph (1), of the supervisor or district deputy by demonstrating compliance with subparagraphs (A) and (B) of paragraph (1). (3) An order to plug and abandon a deserted well under this section due to the supervisor’s or district deputy’s determination of an operator’s noncompliance with either subparagraph (A) or (B) of paragraph (1) may be appealed to the director pursuant to the procedures specified in Article 6 (commencing with Section 3350).

Cal. Public Resources Code - PRC § 3238. Section 3238.

(a) For oil and gas produced in this state from a well that qualifies under Section 3251 or that has been inactive for a period of at least the preceding five consecutive years, the rate of the charges imposed pursuant to Sections 3402 and 3403 shall be reduced to zero for a period of 10 years. The supervisor or district deputy shall not permit an operator to undertake any work on wells qualifying under Section 3251 unless the mineral rights owner consents, in writing, to the work plan. (b) An operator who undertakes any work on a well qualifying under Section 3251 shall have up to 90 days from the date the operator receives written consent from the supervisor to evaluate the well. On or before the 90 day evaluation period ends, the operator shall file with the supervisor a bond or security in an amount specified in Section 3204, 3205, or 3205.1, in accordance with the requirements of whichever of those sections is applicable to the well, if the well operations are to continue for a period in excess of the 90-day evaluation period. The conditions of the bond shall be the same as the conditions stated in Section 3204. (c) A party may plug and abandon a well that qualifies under Section 3251 by obtaining all necessary rights to the well. That party shall be subject to the requirements of this chapter as an operator of the well, file with the supervisor the appropriate bond or security in an amount specified in Section 3204, 3205, or 3205.1, and complete the abandonment. If the abandonment is not completed, the supervisor may act under Section 3226 to complete the work.
