What is the minimal acceptable capacity for spill containment according to UST regulations?

The minimal acceptable capacity for spill containment according to UST regulations is indeed 5 gallons. This requirement is in place to ensure that any spills that occur during day-to-day operations or emergencies are adequately contained to prevent environmental contamination and promote safety. A containment system with a capacity of at least 5 gallons is deemed sufficient to manage potential spills from tanks or associated equipment, allowing for quick response and minimizing the risk of hazardous material leakage into the surrounding environment.

Understanding this requirement is crucial for compliance with environmental protection regulations and helps in maintaining the integrity of underground storage systems. A containment capacity that is lower than 5 gallons would not provide the necessary protection and risk management needed in the event of a spill, underscoring the importance of adhering to this specific regulatory standard.
