Owning a gas station means more than keeping the pumps running and customers happy — it also means protecting your business from costly fines and environmental risks. One of the most important pieces of that puzzle? Staying compliant with Underground Storage Tank (UST) regulations.
At Moran Rocks LLC, we help gas station owners like you simplify environmental compliance. In this post, we’ll break down what you really need to know about UST rules — and give you a handy monthly inspection checklist to keep your site safe and compliant.
🚨 Why UST Compliance Matters
Most gas stations use underground storage tanks to hold petroleum or hazardous substances. While these tanks are essential, they also pose a big risk if not maintained properly. Leaking USTs can contaminate soil and groundwater — leading to cleanup costs, penalties, and even lawsuits.
That’s why the U.S. Environmental Protection Agency (EPA) and your state environmental agency require strict UST management.
📜 What the Law Requires
Federal UST regulations (40 CFR Part 280) apply to most tanks storing petroleum or hazardous substances. Here’s what owners and operators are typically required to do:
- Prevent leaks by using approved tank systems with corrosion protection and leak detection
- Perform monthly and annual inspections to make sure equipment is working properly
- Test leak detection and spill prevention systems regularly
- Maintain records of inspections, repairs, and testing — often for at least 3 years
- Train staff as Class A, B, or C operators, depending on their roles
Your state may have additional rules (many do), so always double-check local requirements or ask a consultant for help.
🛠️ Common Compliance Issues We See
Even responsible owners can miss small — but costly — things. The most frequent problems we find when visiting stations include:
- Broken spill buckets
- Alarms disabled or ignored
- No documentation of monthly inspections
- Failure to test overfill prevention equipment
- Staff not trained on emergency procedures
The good news? These issues are 100% preventable.
