What Are Underground Storage Tanks and Why Compliance Matters
Underground Storage Tanks (USTs) store fuels, oils, and other hazardous substances. Aging or undocumented tanks can leak, leading to soil and groundwater impacts, costly cleanup, and regulatory enforcement. Working with certified professionals ensures your closure meets requirements from CUPA, County Environmental Health, Regional Water Quality Control Boards (RWQCBs), and Air Quality Management Districts. California’s Health & Safety Code §25291(a)(1)-(6) requires non-compliant USTs to be removed or permanently closed by December 31, 2025. Starting early avoids permitting delays, contractor bottlenecks, and potential penalties.Why UST Compliance Matters
- Reduce risk: Prevent soil/groundwater contamination and vapor intrusion.
- Avoid penalties: Minimize violations, shutdowns, and enforcement actions.
- Protect value: Support real estate transactions and redevelopment timelines.
- Document compliance: Achieve agency approvals and No-Further-Action (NFA) determinations.
Key regulators: CUPA, County Environmental Health, RWQCBs, AQMDs, local Fire Departments.

Under California Health & Safety Code §25291(a)(1)-(6), USTs that lack required upgrades (e.g., secondary containment, approved monitoring) or are no longer in use must be closed or removed by December 31, 2025. Tanks that fail inspection or integrity testing also trigger closure requirements.- What it means: If your tank is non-compliant or inactive, begin the closure process now to secure permits, schedule field activities, and complete regulatory review on time.
