19 Months Past Deadline, California's First Carbon Vault Starts Without State Rules

For the climate and energy sector, CRC's injection marks a tangible step toward California's net-zero goals. Yet the regulatory vacuum undermines the very promise of CCS as a safe, permanent climate solution. Without robust state oversight, a single leak or operational mishap could set back public acceptance and investment in carbon removal just as the technology is attempting to scale, potentially stalling a critical decarbonization pathway.

In May 2026, California Resources Corp. (CRC) began injecting carbon dioxide into the Elk Hills oil field, marking the state's first operational carbon capture and storage (CCS) project. The milestone, however, arrived in a regulatory vacuum: California has missed its own statutory deadline by more than 19 months to establish rules governing long-term liability, monitoring, and financial assurance for such projects. Without these rules, the state cannot enforce standards stricter than the federal EPA's permit, leaving critical questions about who bears responsibility if the stored carbon leaks or causes harm.

The void traces back to legislation passed nearly four years ago, when California lawmakers ordered regulators to create a comprehensive carbon storage framework by January 2025. The law specifically required companies to demonstrate financial capacity for cleanup and damages, and it mandated a single coordinated permit across multiple state agencies. But as of August 2026, those rules remain unadopted, even as the first project has moved forward under federal approval alone.

Elk Hills, a sprawling, century-old oil field in rural Kern County, is operated by CRC, the state's largest oil producer. The project's start signals the nascent CCS industry's arrival in California, a state that has staked part of its climate ambitions on carbon removal technologies. The California Air Resources Board's 2022 scoping plan envisions millions of metric tons of annual carbon capture by 2030 as essential to reaching net-zero emissions by 2045. Yet the current regulatory gap threatens to undermine public trust and investor confidence in the technology's safety and permanence.

The core risk is liability. If a CO2 leak occurs—whether from a wellbore failure, an unexpected fault, or operational errors—the gas can pose asphyxiation risks to workers or nearby residents, contaminate groundwater, and release the climate pollutant back into the atmosphere. Under the federal EPA's Class VI permit, the operator must monitor the site and take corrective action, but the state's missing rules prevent California from imposing additional financial responsibility requirements, mandatory insurance levels, or dedicated remediation funds. This leaves communities and taxpayers potentially on the hook for costs if the operator becomes insolvent or disputes its obligations.

Environmental justice advocates have long warned that carbon storage projects are often sited in disadvantaged areas like Kern County, where oil and gas infrastructure already burdens residents. The absence of state-level accountability heightens those concerns, as local oversight is fragmented and under-resourced. The delay also creates legal uncertainty for the project operator: without clear state liability standards, CRC faces potential litigation over future incidents from common law nuisance or trespass claims, but also lacks the regulatory certainty that could protect it from protracted legal battles.

The EPA's approval of the Elk Hills injection well shows that federal regulators believe the project meets basic safety requirements, but federal oversight is inherently limited in addressing cumulative impacts and the long-term stewardship that carbon storage demands—potentially centuries. States like Louisiana and North Dakota have moved to secure primacy over Class VI permitting, aiming to develop more tailored regulations. California's inaction, by contrast, leaves it unable to assert state-level primacy and forces reliance on a one-size-fits-all federal framework.

The delay also carries financial implications. CRC's project will generate compliance credits under California's Low Carbon Fuel Standard, potentially worth tens of millions of dollars annually. Without robust state oversight, the integrity of those credits could be challenged, affecting the broader carbon market. Investors in CCS projects require clear, enforceable rules to price risk; California's regulatory uncertainty may dampen the flow of capital into additional projects.
