If you own or manage a property with a petroleum storage tank (PST), chances are you’ve wondered at some point: Am I really in compliance? The truth is, most people don’t realize they’re breaking regulations—until they get hit with a fine or, worse, forced to shut down operations.

As environmental consultants with over 30 years of experience in Petroleum Storage Tank Compliance across Texas, we’ve seen it all. From forgotten paperwork to broken overfill alarms, small issues can quickly snowball into costly violations. But the good news is: most of it is avoidable—if you know what inspectors are actually looking for.

This guide breaks it down in plain language so you’re prepared before the inspector shows up—and fully ready to pass your next Petroleum Storage Tank Compliance audit.

Why Petroleum Storage Tank Compliance Even Matters

Think of Petroleum Storage Tank Compliance as the safety net that keeps your business running smoothly. The Texas Commission on Environmental Quality (TCEQ) has strict rules in place to prevent environmental contamination from PSTs—especially underground tanks. A leaking tank doesn’t just affect your property; it can contaminate soil, groundwater, and even harm surrounding neighborhoods.

One of our clients, a small trucking company, didn’t realize their tank was missing monthly leak detection logs for over six months. When the inspector came by, they were fined over $15,000. That hurt. What made it worse? It could’ve been avoided with a simple logbook.

Bottom line: staying compliant protects you, your business, and your community—and staying ahead of Petroleum Storage Tank Compliance requirements can save you thousands in fines and downtime.

What Inspectors Are Really Looking For During a Petroleum Storage Tank Compliance Audit

Let’s get into the nitty-gritty. When an inspector visits your site, they’re not just eyeballing the tank—they’re following a comprehensive Petroleum Storage Tank Compliance checklist. Here’s what they focus on the most:

1. Registration and Documentation

Before they even look at the tank, inspectors will ask for paperwork.

• Is your PST registered with TCEQ?

• Can you provide proof of installation, upgrades, and maintenance?

• Do you have financial assurance in place (like pollution liability insurance)?

Keep a binder or digital folder with every inspection report, repair receipt, and permit. Having this ready shows you take Petroleum Storage Tank Compliance seriously—and makes the inspection process smoother.

2. Leak Detection

This is one of the top concerns for regulators.

• Are you using approved monthly monitoring methods like interstitial monitoring or automatic tank gauges (ATGs)?

• Can you show documentation proving consistent monthly checks?

• Are your sensors and equipment fully operational?

We’ve walked into facilities where the leak detection system was plugged in but hadn’t been calibrated in years. Inspectors aren’t just checking for equipment; they’re checking that you’re using it the right way. Poor leak detection is one of the fastest ways to fall out of Petroleum Storage Tank Compliance.

3. Spill and Overfill Prevention

Every PST should have systems in place to prevent spills and overfills during fuel deliveries.

• Spill buckets: Are they clean, intact, and free of debris or fuel?

• Overfill protection: Does your system shut off automatically or alert you before reaching capacity?

One client told us, “Oh, we just keep an eye on it during deliveries.” That’s not enough. PST Compliance requires mechanical or electronic prevention methods—not just human observation.

4. Corrosion Protection

If your tank or piping is made of metal, it must have a working corrosion protection system—typically cathodic protection.

• Is your cathodic protection system being tested regularly (usually every 3 years)?

• Do you have records of the most recent test and maintenance?

We once discovered a tank’s cathodic system had been nonfunctional for months because someone had unplugged the power source. The result? Costly repairs and a full regulatory review. Don’t let simple oversights jeopardize your PST Compliance.

5. Operator Training

Properly trained staff are essential for staying compliant.

• Class A Operator: Oversees overall compliance.

• Class B Operator: Manages daily operations.

• Class C Operator: First responder to spills or issues (usually on-site staff).

Inspectors will ask for documentation proving that training is current. If no one knows what to do during a spill or system alert, that’s a red flag for Petroleum Storage Tank Compliance violations.

Most Common Petroleum Storage Tank Compliance Violations We See (And How to Fix Them)

Even well-meaning owners miss things. Here are the issues we run into most often:

Missing Documentation

This one’s easy to fix. Create a paper or digital system to track everything: inspections, maintenance, monthly checks, fuel deliveries—you name it. Organized records are a core part of Petroleum Storage Tank Compliance.

Inactive or Uncalibrated Equipment

Having equipment is not the same as using it properly. Schedule regular maintenance and calibration for sensors, alarms, and gauges. Inspectors will check.

Skipped Monthly Walkthroughs

You’re expected to inspect your tank and components visually every month. Use a checklist, take pictures, and record the inspection. This shows you’re actively managing Petroleum Storage Tank Compliance.

Cracked or Overflowing Spill Buckets

Spill buckets need to be free of standing water, fuel, and cracks. Clean and inspect them regularly. These are a small detail that makes a big difference during inspections.

How to Prepare for a Petroleum Storage Tank Compliance Audit

So, what can you do today to avoid being caught off guard? Here’s how to stay audit-ready and stress-free:

Step 1: Perform a Self-Audit

Use the same checklist that TCEQ inspectors use—or better yet, bring in an environmental professional for a mock inspection.

Step 2: Organize Your Records

Keep permits, test results, training certificates, and inspection logs in one place. Inspectors love when you’re prepared.

Step 3: Schedule Preventive Maintenance

Don’t wait until something breaks. Regular upkeep shows that you’re committed to Petroleum Storage Tank Compliance and helps you avoid unexpected failures.

Step 4: Train Your Team

Make sure your Class A, B, and C operators are trained, documented, and prepared. Hold refresher training yearly and update your compliance logs.
