AB 1536 California Assembly · 2025-2026 Regular Session

Offshore oil: pipeline safety.

Summary
The Elder California Pipeline Safety Act of 1981 requires the State Fire Marshal to administer provisions regulating the inspection of intrastate pipelines that transport hazardous liquids. The act requires the State Fire Marshal to adopt hazardous liquid pipeline safety regulations in compliance with the federal law relating to hazardous liquid pipeline safety, as provided. The act authorizes the State Fire Marshal to exempt the application of those regulations to any pipeline, or portion thereof, when it is determined that the risk to public safety is slight and the probability of injury or damage remote. The act requires any new or replacement pipeline near environmentally and ecologically sensitive areas in the coastal zone to use best available technology based on a risk analysis conducted by the operator to reduce the amount of oil released in an oil spill to protect state waters and wildlife. A person who willfully and knowingly violates the act or a regulation issued pursuant to the act is, upon conviction, subject to a fine, imprisonment, or both a fine and imprisonment, as provided. This bill would make an application for a specified exemption pursuant to these provisions subject to a 60-day public comment period and, upon request of any interested person, require it to be considered at a public hearing. The bill would make a project that has received an exemption from the State Fire Marshal, as described above, subject to the California Environmental Quality Act. The bill would make any repaired pipeline near environmentally and ecologically sensitive areas in the coastal zone subject to the requirement to use best available technology based on a risk analysis conducted by an independent expert, rather than the operator, and require that analysis to address prevention, as well as reduction, of the amount of oil released in an oil spill, as described above, and make related changes. The bill would prohibit idled, inactive, or out-of-service hazardous liquid pipelines under the jurisdiction of the State Fire Marshal that have experienced a reportable incident, such as a hazardous liquid spill, from being reactivated or operated, unless specified conditions are met. The bill would require, for any idled, inactive, or out-of-service pipeline that has spilled 10,000 gallons or more of hazardous liquid, the operator to permanently abandon the pipeline by July 1, 2027, or within 6 months of the pipeline's most recent incident, and require the operator to restore the site to its natural condition no later than one year following permanent abandonment. By creating new crimes, the bill would impose a state-mandated local program. This bill would require the State Fire Marshal to require permanent abandonment of a pipeline if the best available technology is not achievable for a pipeline because of operational aspects, pipeline or regional conditions, or other factors. The bill would require the State Fire Marshal to suspend the operations of any pipeline that is not in compliance with the requirements to use best available technology no later than January 1, 2027. Existing law establishes the Geologic Energy Management Division in the Department of Conservation, under the direction of the State Oil and Gas Supervisor, who is required to supervise the drilling, operation, maintenance, and abandonment of oil and gas wells, as provided. A person who violates, fails, neglects, or refuses to comply with the oil and gas laws, or who fails, neglects, or refuses to furnish any report or record required pursuant to those laws, is guilty of a crime. This bill would require an operator seeking approval for a new well, production facility, or specified pipelines in the coastal zone to submit an oil leak detection and response plan, as specified, and obtain approval from the division before obtaining approval for the new well, production facility, or specified pipeline. By creating new crimes, the bill would impose a state-mandated local program. Existing law authorizes the Department of Parks and Recreation to grant permits and easements to an oil and gas lessee of the state for pipeline right-of-way purposes. This bill would prohibit any intrastate oil pipeline that has spilled 10,000 gallons or more of oil cumulatively since its construction from operating within 0.5 miles of a state park, a designated ecological reserve, as defined, or a wildlife area, as determined by the Fish and Game Commission. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that no reimbursement is required by this act for a specified reason.

MAJOR
The April 6 amendment to AB 1536 makes several substantive changes to California's offshore oil pipeline safety framework. Most significantly, it reverses the default on pipeline exemptions from 'may exempt when risk is slight' to 'shall not exempt unless there is a threat to public safety or the environment,' adds a new requirement for pipelines to have both computational and sensory leak detection methods, requires independent expert risk analyses instead of operator-conducted ones, and removes a legislative intent section about future offshore oil permitting legislation.
REQUIREMENT

Section 51011(b) flips the exemption standard: previously the State Fire Marshal 'may exempt' pipelines when risk is slight and injury probability is remote; now the State Fire Marshal 'shall not exempt' unless the exemption is necessary to address a threat to public safety or the environment or other emergency. This makes exemptions far harder to obtain.

New Section 3239(b)(2) requires that leak detection and response plans for pipelines under State Fire Marshal jurisdiction meet or exceed federal requirements (49 CFR 195.452) and must include both an internal computational method AND an external or sensory method for leak detection. Previously, a single standard applied to all facility types.

Section 51013.1(a) now requires risk analyses for new, repaired, or replacement pipelines near sensitive coastal areas to be conducted by an independent expert rather than the operator, and must address both prevention and reduction of oil releases (previously only reduction was mentioned for new pipelines).

TIMELINE

The deadline for the State Fire Marshal to adopt regulations under Section 51013.1 is changed from July 1, 2017 to July 1, 2027, giving a full decade more time.

SCOPE

The entire section stating legislative intent to enact subsequent legislation regarding offshore oil permitting authority and protections for communities impacted by offshore oil transportation was removed from the bill.

Section 5012.3 broadens the geographic restriction on pipelines that have spilled 10,000+ gallons: the prohibited operating zone now extends to 'a park, a designated ecological reserve, or a wildlife area of California' rather than only 'a state park, wildlife area, or ecological reserve,' potentially covering local parks and adding the qualifier 'designated' for ecological reserves.

Section 3239(d) expands the California Coastal Commission's authority to adopt leak detection and repair standards that are more protective than both state division standards AND federal regulations (previously only state standards were referenced).

ENFORCEMENT

New Section 51011(d) requires that notification of any pipeline exemption be written, publicly available, and include a discussion of the factors the State Fire Marshal considered significant in granting the exemption.

TECHNICAL

Fiscal committee designation changed from 'no' to 'yes' and state-mandated local program designation changed from 'no' to 'yes,' indicating the bill now triggers additional fiscal review requirements.
