Fuel Spill Prevention and Cleanup: Protecting Your Land and Water

Keeping Fuel Where It Belongs: In Your Tanks, Not Your Soil

A fuel spill on your ranch can contaminate soil, pollute groundwater, kill vegetation, and harm livestock. Beyond the environmental damage, spills create serious legal and financial liability. Cleanup costs can easily exceed $10,000 to $100,000 or more depending on the extent of contamination, and regulatory fines add to the burden.

Prevention is far cheaper than cleanup. Knowing how spills happen and putting protective measures in place keeps fuel where it belongs.

Spill Risks on the Ranch

Common Causes of Spills

Where Spills Occur

• During equipment refueling
• At dispensing areas
• During fuel transfer
• From storage tank leaks
• From failed equipment seals/lines

Environmental Fate of Spilled Fuel

When fuel hits the ground, it follows a predictable path. It spreads across the surface first, then penetrates the soil moving vertically downward. Given enough volume and time, it reaches the water table and contaminates groundwater. Volatile components also evaporate into the air. How far and how fast contamination spreads depends on water table depth, spill volume, how long before cleanup begins, and whether the product is gasoline (which moves faster) or diesel.

Prevention Strategies

Tank and Equipment Design

Secondary containment is your first line of defense. Double-wall tanks, containment pallets for drums, and drip pans under connections all catch fuel before it reaches the ground. Containment capacity should be 110% of the largest tank, or 100% of the largest plus 10% of the aggregate. Overfill protection, including high-level alarms, visual or audible warnings, and proper gauging, prevents the most common cause of spills.

Delivery Procedures

Before delivery: Verify the tank gauge reading, position absorbent material around connections, stay present throughout the delivery, and know the emergency shutoff location.

During delivery: Maintain communication with the driver, watch for leaks at connections, and be ready to stop the fill at any moment.

After delivery: Verify the quantity delivered, secure all connections, and document the delivery.

Refueling Procedures

Good refueling habits prevent most small spills. That means not overfilling (leave room for expansion), using drip pans where appropriate, cleaning up drips immediately, and maintaining equipment in good condition.

Maintenance Prevention

Check tank integrity, secondary containment, and valves and fittings monthly. Test overfill devices before each delivery. Replace fittings showing corrosion, seals that show leakage, and equipment past its service life.

Spill Response Procedures

Immediate Actions (First 5 Minutes)

• STOP the source: Close valves, upright containers, plug leaks if safe, and turn off pumps.
• CONTAIN the spread: Deploy absorbent booms, build earthen dikes if needed, block drains and culverts, and prevent runoff to water.
• PROTECT yourself and others: Eliminate ignition sources, use appropriate PPE, keep others away, and establish a safety perimeter.
• CLEAN UP: Apply absorbent, collect contaminated material, and prevent further spread.

Small Spills (Under 5 Gallons)

• Stop the source
• Eliminate ignition sources
• Apply absorbent (from edges inward)
• Allow time for absorption
• Sweep up contaminated absorbent
• Place in proper container
• Check for soil staining
• Remove contaminated soil if present
• Dispose of waste properly
• Document incident

Medium Spills (5-25 Gallons)

Follow small spill procedures with additional steps: consider calling for assistance, plan for more extensive soil removal, determine whether reporting is required, and document thoroughly.

Large Spills (Over 25 Gallons)

• Stop the source
• Call TCEQ: 1-800-832-8224
• Contain the spill, but do not attempt extensive cleanup
• Call professional cleanup contractor
• Keep others away
• Document everything
• Cooperate with regulatory agencies

Protecting Water Sources

Prevention

Keep fuel storage at least 100 feet from surface water, above flood elevation, and away from drainage paths. Berms should direct any potential spill away from water, and impervious surfaces in fueling areas add another layer of protection.

If a Spill Threatens Water

• Stop the source immediately
• Call TCEQ immediately
• Attempt to intercept before fuel reaches water
• Use booms if product reaches water surface
• Do NOT flush the spill toward water
• Professional help required

Soil Contamination

Assessment

Signs of soil contamination include fuel odor, discolored soil, dead or dying vegetation, and sheen in low areas after rain.

Cleanup Approaches

For small contamination, remove affected soil, place it in containers or on plastic sheeting, allow volatiles to evaporate in a controlled setting, and dispose of it properly or remediate on-site. Larger contamination may require excavation, groundwater monitoring, and regulatory involvement.

Disposal of Contaminated Soil

Approved methods include landfarming (under permit), bioremediation, and thermal treatment. Never dump contaminated soil in regular trash, bury it without treatment, or burn it.

Reporting Requirements

When to Report

Report to the state when a release exceeds 25 gallons, when a release leaves your property, or when any release occurs from a regulated UST. Federal reporting is required when a release of a hazardous substance exceeds the reportable quantity.

What to Report

Provide the location of the spill, date and time of the release, product type and quantity, actions taken, and any impacts observed.

Documentation

Keep records of the time the spill was discovered and reported, all actions taken, cleanup methods, disposal documentation, costs incurred, and photos taken before, during, and after cleanup.

Waste Disposal

Contaminated Materials

Waste from fuel spills includes contaminated soil, used absorbent, contaminated PPE, contaminated containers, and rinsewater. Keep everything secure until proper disposal. Use a licensed hazardous waste facility and maintain disposal documentation.

Used Absorbent

Some facilities accept lightly saturated absorbent as solid waste, and some permitted facilities can use it as a fuel supplement. Never burn used absorbent on-site.

Financial Considerations

Cleanup Costs

Insurance Considerations

Review your policy now, before a spill happens. Key questions: What are the deductibles? Are there exclusions for fuel storage? What documentation is required? If a spill does occur, document thoroughly, don't admit liability prematurely, and cooperate with your insurer.

Prevention Inspection Checklist

Daily

• Visual check of tanks for leaks
• Check dispensing area for spills
• Verify caps and connections secure

Weekly

• Tank gauge reading and comparison
• Inspect hoses and connections
• Check containment area condition
• Verify spill kit availability

Monthly

• Inventory reconciliation
• Detailed tank inspection
• Equipment maintenance check
• Containment integrity verification
• Spill kit inventory

Annually

• Professional tank inspection
• Evaluate prevention measures
• Update response procedures
• Conduct training
• Review with insurance carrier

SPCC Plan Requirements

When Required

An SPCC plan is required when total aboveground oil storage exceeds 1,320 gallons and there's a reasonable expectation that a spill could reach navigable waters. A farm exemption exists for facilities with aggregate capacity under 6,000 gallons.

Plan Contents

The plan must address potential spill sources, prevention measures, countermeasures for spills, training requirements, and the inspection schedule.

Professional Engineering

A plan must be certified by a Professional Engineer when a single tank exceeds 660 gallons without secondary containment, or when other specific triggers apply.

Bottom Line

Prevention costs a fraction of what cleanup does, making every dollar spent on containment, overfill protection, and maintenance a sound investment. Secondary containment catches problems before they become disasters, and since overfills cause 40% of all spills, staying attentive during filling operations is the single most impactful habit you can build.

Keep spill kits equipped and accessible at every fuel location, and make sure everyone who handles fuel knows how to use them. When a spill exceeds 25 gallons or threatens water, call TCEQ at 1-800-832-8224. Protect water sources first, because groundwater contamination is the most expensive outcome by far.

Document everything with photos, notes, and receipts. Know your limits and call professionals for large spills rather than trying to handle them yourself. All contaminated materials are regulated waste that must be disposed of properly. Train everyone who handles fuel on both prevention and spill response, because the time to learn isn't while fuel is spreading across the ground.
