Introduction
Above ground diesel tanks are widely used for storing and dispensing diesel fuel in industries such as agriculture, construction, transportation, and emergency power generation. Unlike underground tanks, these storage solutions are easier to install, maintain, and relocate, making them a flexible and cost-effective choice for businesses and individuals.
This guide explores the types, benefits, safety considerations, and regulatory compliance of above ground diesel tanks to help you select the best option for your needs.
Types of Above Ground Diesel Tanks
1. Single-Wall vs. Double-Wall Tanks
- Single-Wall Tanks – Made from a single layer of steel, aluminum, or polyethylene. These are cost-effective but require secondary containment to prevent spills.
- Double-Wall Tanks – Feature an inner and outer shell with an interstitial space for leak detection. They provide enhanced spill protection and are often required in regulated industries.
2. Material Options
- Steel Tanks – Durable and long-lasting, often galvanized or powder-coated for corrosion resistance. Best for heavy-duty industrial use.
- Aluminum Tanks – Lightweight and rust-resistant, ideal for mobile applications and harsh environments.
- Polyethylene (Plastic) Tanks – Non-corrosive, UV-resistant, and suitable for outdoor storage without additional coatings.
3. Tank Designs & Configurations
- Horizontal vs. Vertical Tanks – Horizontal tanks are common for transport and dispensing, while vertical tanks save space in stationary setups.
- Skid-Mounted & Portable Tanks – Equipped with forklift pockets or trailer hitches for easy relocation.
- Bunded (Secondary Containment) Tanks – Include an outer shell to contain leaks, meeting stricter environmental regulations.
Key Benefits of Above Ground Diesel Tanks
- Easy Installation & Maintenance – No excavation required, reducing setup time and costs.
- Mobility & Flexibility – Can be relocated as operational needs change.
- Cost-Effective Storage – Lower initial investment compared to underground tanks.
- Leak Detection & Prevention – Visible inspection points make leaks easier to identify early.
- Compliance with Regulations – Many models meet EPA, OSHA, and local fire safety standards.
Safety & Regulatory Compliance
1. Spill Prevention & Containment
- Secondary Containment – Required in many regions to prevent soil and water contamination.
- Overfill Protection – Automatic shutoff valves and alarms prevent spills during refueling.
- Ventilation & Vapor Control – Proper venting prevents pressure buildup and reduces fire hazards.
2. Fire Safety Measures
- Distance from Structures – Tanks should be placed at least 40 feet from buildings (varies by jurisdiction).
- Fire-Resistant Barriers – Some regulations require diking or firewalls around tanks.
- Static Electricity Prevention – Grounding straps and bonding wires minimize ignition risks.
3. EPA & Industry Regulations
- EPA Spill Prevention, Control, and Countermeasure (SPCC) Rules – Apply to tanks holding more than 1,320 gallons.
- DOT Compliance – Required for transportable tanks exceeding certain capacities.
- Local Fire Codes – Check municipal regulations for tank placement and safety requirements.
Applications of Above Ground Diesel Tanks
- Agriculture – Storing fuel for tractors, irrigation pumps, and harvesters.
- Construction Sites – On-site refueling for generators and heavy machinery.
- Fleet Management – Fueling trucks, buses, and equipment without visiting gas stations.
- Emergency Backup Power – Storing diesel for generators in hospitals, data centers, and remote facilities.
- Military & Disaster Relief – Rapid deployment of fuel supplies in critical situations.
Choosing the Right Above Ground Diesel Tank
Consider the following factors when selecting a tank:
- Capacity Needs – Match tank size to fuel consumption (common sizes: 100–10,000+ gallons).
- Material & Durability – Choose steel, aluminum, or polyethylene based on environmental conditions.
- Portability Requirements – Skid-mounted or trailer-compatible tanks for mobile operations.
- Regulatory Compliance – Ensure the tank meets EPA, OSHA, and local fire codes.
- Additional Features – Look for built-in pumps, filtration systems, and lockable access points.
Maintenance & Best Practices
- Regular Inspections – Check for leaks, corrosion, and structural damage.
- Proper Labeling – Clearly mark tanks with fuel type and hazard warnings.
- Fuel Quality Management – Use additives and filters to prevent contamination.
- Spill Response Plan – Keep absorbent materials and containment kits nearby.
Conclusion
Above ground diesel tanks offer a practical and efficient solution for fuel storage across multiple industries. By understanding the different types, safety regulations, and maintenance requirements, you can ensure safe, compliant, and cost-effective fuel management.
