Tag: Storage Tank Selection

Fuel storage is critical in many industries, including gas stations, manufacturing, and transportation. When it comes to fuel storage tanks, there are two primary options to consider: underground fuel storage tanks (USTs) and aboveground fuel storage tanks (ASTs). Each type has its advantages and disadvantages, making the choice between them an important decision. Experts at API inspection companies suggest tank operators to make a careful choice when picking fuel storage tanks.

In this article, we’ll compare USTs and ASTs, helping you understand which is the better fit for your needs is.

Underground Fuel Storage Tanks (USTs)

Underground fuel storage tanks are, as the name suggests, buried beneath the ground. They are favored for various reasons:

• Space Efficiency: USTs don’t take up valuable surface space, making them ideal for locations with limited land availability.
• Aesthetics: The underground placement keeps the landscape uncluttered and maintains a pleasing aesthetic, which can be important for commercial and residential areas.
• Protection from Environmental Elements: Being underground provides some natural insulation against temperature fluctuations, potentially extending the life of the tank and fuel.
• Reduced Fire Risk: USTs are less susceptible to fires and vandalism, providing a higher level of security for the stored fuel.

 However, USTs also come with their own set of challenges:

• Installation and Maintenance: USTs require skilled professionals for installation and routine maintenance. Leaks or damages can be challenging to detect, and addressing them often involves excavation.
• Compliance and Regulation: Environmental regulations, especially related to groundwater protection, are stringent for USTs. Compliance and monitoring requirements can be rigorous.
• Higher Initial Costs: USTs typically cost more to install than ASTs due to excavation and the need for corrosion-resistant materials. Besides this, the tank inspection services are also expensive.

 Aboveground Fuel Storage Tanks (ASTs)

Aboveground fuel storage tanks are a more visible option, located on the surface and often enclosed within protective structures. They have several advantages:

• Accessibility: ASTs are easier to access for inspection, maintenance, and repairs. Any issues can be quickly identified and addressed.
• Easier Compliance: ASTs are subject to fewer complex regulations and compliance standards than USTs, reducing the administrative burden.
• Cost-Effective Installation: Installation costs for ASTs are generally lower since they don’t require excavation. Moreover, their surfaces allow for easy addition of safety features, such as secondary containment systems.
• Diversity of Sizes and Shapes: ASTs are available in various sizes and can be customized to fit specific requirements.

 However, ASTs have their challenges:

• Land Space: They require surface space, which might be a limitation in certain settings.
• Aesthetics: Some may consider them less aesthetically pleasing, which could be a concern in residential or commercial areas.
• Environmental Impact: ASTs are more susceptible to environmental elements, which can impact fuel quality and safety if not properly maintained.

 Selecting the Right Tank

Choosing between USTs and ASTs should be based on specific needs, and several considerations can help guide your decision:

• Space Availability: Consider the available space at your location. If land is abundant, ASTs may be a more practical option. For limited space, USTs offer a space-efficient solution.
• Regulatory Compliance: Research local, state, and federal regulations regarding fuel storage. Compliance requirements vary based on the type of tank and its location.
• Aesthetics: Consider the aesthetics of the surroundings. In residential or commercial areas, the visual impact of ASTs might be a concern.
• Maintenance and Inspection: If easy access for routine maintenance is essential, ASTs are the more convenient choice.
• Cost Considerations: Factor in the installation, maintenance, and long-term costs, which can vary significantly between the two tank types.

 Conclusion

USTs and ASTs each have their strengths and weaknesses. Choosing the right fuel storage solution depends on factors like available space, regulatory compliance, aesthetics, maintenance requirements, and costs. Ensuring you make the right choice is crucial to safe and efficient fuel storage, as well as maintaining compliance with local regulations and protecting the environment. If you’re unsure which option is best for your specific needs, consulting with professionals and regulatory authorities is a wise step to take.…
