What is an Above-Ground Storage Tank

Above-ground storage tanks are a significant part of Florida’s infrastructure, with nearly 24,000 regulated facilities statewide. Since adopting of AST regulations in 1983, there has been a robust framework to ensure safety and compliance. These tanks commonly store petroleum and hazardous chemicals, making them integral to various industries.
The types of substances stored in ASTs are diverse, ranging from food ingredients to petroleum products and hazardous chemicals. This versatility highlights the importance of stringent regulations and best practices to prevent environmental contamination and ensure public safety.
From fueling stations to industrial facilities, aboveground storage tanks are ubiquitous in Florida. Their prevalence underscores the need for comprehensive guidelines and regular inspections to maintain operational safety and environmental protection.
Regulatory Authority: Florida Department of Environmental Protection
The Florida Department of Environmental Protection (DEP) is the primary regulatory authority overseeing compliance for both underground and aboveground storage tank systems. Since 1983, the DEP has established a robust framework of regulations to ensure AST safety. In 2023 alone, compliance inspectors conducted over 11,000 inspections at nearly 24,000 regulated storage tank facilities in Florida.
Facilities with ASTs must also comply with the U.S. EPA’s Spill Prevention, Control, and Countermeasure (SPCC) regulations, which mandate detailed plans to prevent oil spills from reaching navigable waters. Additional state and local regulations further safeguard human health and the environment, ensuring that facilities manage hazardous materials responsibly.
Registration and Notification Requirements
All regulated aboveground storage tanks must be registered with the Florida Department of Environmental Protection. This process ensures that storage tank systems containing motor fuel comply with state regulations. The registration process involves submitting necessary documentation to the DEP, which helps maintain an up-to-date inventory of storage tanks in the state.
Operators must also notify the DEP at least 30 days in advance of any significant changes to their storage tank operations. This includes notifying local authorities of changes to ensure that all relevant parties are aware and prepared for any potential impacts.
Installation Standards and Guidelines
Proper installation of aboveground storage tanks is crucial for safety and compliance. Essential guidelines include maintaining a minimum distance of three feet between flammable storage tanks and other structures, and ensuring that tanks are not located less than 25 feet from any building. Barriers such as concrete pillars or pipe bollards should be installed to protect fuel tanks from potential damage.
Secondary containment systems and leak detection mechanisms are mandatory to minimize environmental impact. Overfill protection features are also required to prevent spills during filling operations. Additionally, adequate lighting is necessary to facilitate nighttime inspections for potential leaks around fuel tanks.
Double-walled tanks are recommended over single-wall tanks as they provide better protection against leaks and external damage. Single-wall tanks must be placed in diked areas capable of containing 110% of the largest tank’s volume. These installation standards are designed to ensure that ASTs operate safely and efficiently.
Operational Compliance and Maintenance
Maintaining operational compliance is critical for the safe management of aboveground storage tanks. Owners and operators must adhere to guidelines provided by the Florida DEP, which include conducting regular inspections and maintaining proper records. Monthly inspections are required to check for leaks and other damages, ensuring that tanks remain in safe and operable condition.
Training and certification for personnel managing storage tanks are essential to maintain compliance with Florida’s safety and environmental regulations. Proper documentation of inspections, maintenance activities, and compliance reports is crucial for regulatory review. By keeping detailed records, operators can demonstrate their commitment to safety and compliance.
Owners and operators of ASTs must maintain tanks and associated equipment in a safe and operable condition. This proactive approach helps prevent accidents and environmental contamination, protecting both human health and the environment.
Secondary Containment Systems
Secondary containment systems are crucial for capturing spills from primary storage tanks, thereby preventing environmental hazards. These systems are often mandated by regulations to manage hazardous materials responsibly and are particularly important for larger fuel storage facilities.
Different types of containment systems, such as dyke systems and double-walled tanks, provide an outer barrier that captures leaks from the inner tank, preventing environmental exposure. The capacity of a secondary containment system must be adequate to handle the maximum volume of stored materials during a spill.
Regular inspections and maintenance of these systems are essential to ensure their effectiveness in preventing environmental contamination. At EPAC Environmental Services Inc., we offer comprehensive fuel tank services, including installation, maintenance, and removal.
Spill Prevention and Response Planning
Spill Prevention, Control, and Countermeasure (SPCC) plans are vital for having an action plan that may prevent oil spills from reaching navigable waters, thereby protecting the environment. These plans are tailored to each facility, outlining the specific configuration of its aboveground and underground storage tanks.
According to the EPA, an SPCC plan is required if the facility stores a total of more than 1,320 gallons of oil in aboveground containers (only containers with a capacity of 55 gallons or greater), or it stores more than 42,000 gallons of oil in completely buried containers. Facilities like marinas, which are close to water bodies, often have additional requirements for emergency spill response plans due to their unique risks.
Proper planning and preparation are key to mitigating the impact of potential spills and leaks, especially when considering oil before any operations.
Temporary and Portable Fuel Storage Tanks
Temporary and portable fuel storage tanks are used for short-term storage needs, typically between 30 days and one year. These tanks must have a maximum capacity of 2,500 gallons per site and be positioned at least 15 feet away from buildings or property lines. Proper labeling of temporary tanks is essential, including the owner’s name and phone number, alongside the product name displayed in a contrasting color.
Additionally, the surrounding area of temporary fuel tanks must be kept free of combustible materials for at least 15 feet in all directions. Facilities must maintain a substantially level ground under tanks to prevent tipping. These regulations ensure the safe and effective use of temporary fuel storage tanks.
Closure and Removal of Above Ground Fuel Storage Tanks
When it comes time to close and remove an above-ground storage tank, a closure integrity evaluation report is required. This ensures that the tank is free from hazardous substances before removal, following strict decontamination procedures. Proper disposal of any removed tank must comply with local environmental regulations to prevent contamination.
Following these procedures is crucial for minimizing environmental impact and ensuring that the site remains safe for future use. Proper closure and removal of ASTs protect both human health and the environment.
Inspections and Enforcement
The Florida Department of Environmental Protection conducts thousands of inspections annually to ensure compliance among storage tank facilities. Inspections of aboveground tanks are conducted based on specific rules outlined in the Florida Administrative Code. County staff are responsible for carrying out inspections at residential and business facilities for compliance.
Failure to comply with storage tank regulations and applicable rules may result in penalties imposed by the Florida DEP. Regular inspections and enforcement measures are essential for maintaining safety and environmental protection.
Special Considerations for Certain Facilities
Designing fuel storage systems for specific facilities requires careful consideration of the facility’s operational needs and the regulatory framework. These special considerations ensure that ASTs are safe, compliant, and effective in their specific environments.
Impact on Human Health and the Environment
Contamination from AST leaks or spills can lead to serious risks to human health, including contaminated soil, water, or air. The physical condition of ASTs can be influenced by factors such as age, maintenance practices, and environmental pressures, affecting their reliability. Climate change increases the likelihood of extreme weather events, which can lead to faster deterioration of ASTs, posing risks to nearby communities.
Proper management and maintenance of ASTs are crucial for preventing environmental contamination and protecting human health. Understanding potential risks and taking proactive measures helps facilities minimize their environmental impact.
