Understanding California’s Decommissioning Requirements for Gas Stations

Despite California’s love for the open road, changing times and evolving marketplace dynamics are leading some gas station owners to contemplate closing their gas stations. Reasons why station owners might choose to go down this path include the declining demand for fossil fuels, environmental and regulatory concerns, alternative real property uses, business reasons, retirement, or simply a desired change in lifestyle.

California has some of the strictest environmental preservation and clean energy mandates in the nation. These policies make it a complex, multifaceted process for station owners to shut down their operations. If you’re considering going down this road, don’t do it alone. Work with an environmental expert who can handle the necessary decommissioning steps for you. These include the following requirements:

  1. Notifying State Authorities about Your Decommissioning Plans
    The process of shutting down your gas station begins with notifying the relevant regulatory authorities, including the California Department of Toxic Substances Control (DTSC) and the local Certified Unified Program Agency (CUPA). This notification is crucial as the first step in the formal decommissioning process.
  2. Conducting an Environmental Assessment and Cleanup When Necessary
    A primary reason stringent regulations must be followed for gas station closure in California is the potential environmental contamination associated with underground storage tanks (USTs). Before closure, a qualified expert must conduct a comprehensive environmental assessment. This involves inspecting both your USTs and soil to identify signs of leakage. If contamination is detected, you are obligated to conduct a thorough cleanup and remediation.
  3. Decommissioning Your Underground Storage Tanks (USTs)
    Your USTs lie at the heart of your station’s infrastructure. You need to determine which of the following methods you’ll use to decommission your tanks: 
    • Tank Removal: Extracting the UST from the ground, cleaning it, and ensuring its safe disposal prevents an environmental hazard.
    • Tank Abandonment: Filling the UST with concrete or another suitable material renders it permanently inoperable.
  1. Ensuring Regulatory Compliance with State Statutes
    You must comply with numerous regulations during the decommissioning process. These regulations are in place to safeguard public health and the neighboring environment. You must follow the California UST program guidelines, which cover various aspects of UST closure, from safety protocols to waste disposal procedures.
  2. Monitoring and Testing Your Tanks and Surrounding Soil
    Tank decommissioning is part of the process you must undergo, but there are additional steps beyond decommissioning your tanks. You may also be required to conduct post-closure monitoring and testing to ensure no contamination has occurred and the site remains safe. The monitoring process may involve periodic soil and groundwater testing to detect any residual contaminants.
  3. Obtaining the Necessary Permits and Submitting Closure Reports
    Decommissioning your station also requires obtaining the necessary permits for UST removal or closure, as well as for environmental assessments. Additionally, you are required to submit closure reports that document the entire decommissioning process. These reports provide vital information to regulatory agencies and serve as a record of compliance with regulations.
  4. Demonstrating Financial Responsibility
    California law mandates you demonstrate financial responsibility to cover potential cleanup costs in the event of environmental contamination. This is a safeguard to ensure you can financially address any unforeseen environmental damage resulting from potential UST leaks.
  5. Maintaining the Required Records
    Maintaining meticulous records is vital throughout the closure process. Documentation of permits, reports, monitoring data, and other relevant information is essential for regulatory compliance and in the event  future liability issues arise. Keeping records organized and easily accessible is advisable for both current and future reference.

As California continues to embrace cleaner and more sustainable energy solutions, the responsible decommissioning of gas stations becomes increasingly vital. While the closure process may seem daunting, it’s a necessary step to ensure your station can be safely repurposed, so your reputation remains untarnished.
