Above-ground storage tanks (ASTs) are widely used across various industries to store critical liquids such as water, petroleum, chemicals, and more. While these tanks serve as essential storage solutions, leaks and spills pose a significant risk to the environment, human health, and businesses’ bottom line. As a result, it is crucial for businesses to take proactive measures in preventing and mitigating the impacts of potential AST leaks or spills, which includes the strategic implementation of secondary containment systems.
In this informative and relevant blog, we will explore the environmental benefits of incorporating secondary containment solutions for your ASTs, emphasising the importance of safeguarding the environment and adhering to regulatory requirements. We will discuss various secondary containment systems, including impervious liners, double-walled tanks, and berms, which act as additional barriers to prevent spills from reaching the environment, minimising the risk of soil, water, and air contamination.
Lastly, this blog will showcase how ATM Tanks, a leading provider of tank design, installation, repairs, and maintenance across Australia and the Pacific, can assist businesses in designing, installing, and maintaining secondary containment systems for their ASTs. With their expertise and specialised services, ATM Tanks can contribute to the protection of the environment while helping businesses minimise risks and liabilities associated with tank leaks and spills.
Types of Secondary Containment Systems
Secondary containment systems offer a crucial line of defence against leaks and spills from ASTs. Several types of containment solutions are available to suit various tank designs, materials, and storage requirements:
1. Impervious Liners: Made from materials such as polyvinyl chloride (PVC) or high-density polyethylene (HDPE), impervious liners function by creating a physical barrier between the tank and the environment, thereby preventing liquids from seeping into the soil or groundwater beneath the tank.
2. Double-Walled Tanks: These tanks feature an additional outer wall that surrounds the primary storage container, providing added protection in case of leaks or ruptures. With double-walled tanks, any leakages are contained within the secondary enclosure, preventing environmental contamination.
3. Berms and Dikes: Also known as bunding, berms, and dikes are raised barriers typically constructed from earth, concrete or steel that encircle the tank, creating a containment area to hold potential spills. Properly designed containment berms should be able to hold a certain percentage of the tank’s volume in case of a leakage or rupture.
Environmental Benefits of Secondary Containment Systems
Implementing secondary containment systems brings numerous environmental advantages:
1. Preventing Soil Contamination: Containment barriers block direct contact between hazardous fluids and the ground, reducing the risk of soil contamination that could result in long-term environmental damage or hinder future land use.
2. Safeguarding Water Sources: Containment systems help protect surrounding water sources, such as groundwater, rivers, and lakes, from contamination caused by AST leaks or spills. This safeguards the health of ecosystems, wildlife, and human populations reliant on these resources.
3. Reducing Air Pollution: By minimising the release of volatile organic compounds (VOCs) from AST leaks, secondary containment systems can help combat air pollution and mitigate potential human health impacts.
4. Encouraging Sustainable Practices: Implementing secondary containment systems highlights a business’s commitment to environmental protection and sustainability, promoting industry-wide adoption of responsible practices.
Regulatory Requirements for Secondary Containment
Adhering to regulatory requirements for secondary containment is essential for businesses operating ASTs:
1. Containment Capacity: Regulations specify the minimum containment capacity of secondary containment systems, typically a percentage of the tank’s volume, ensuring sufficient capacity to hold potential spills.
2. Material Compatibility: Containment materials must be compatible with the stored liquids, ensuring the continued effectiveness of the containment barrier.
3. Inspection and Maintenance: Regulators require regular inspections and maintenance of secondary containment systems to guarantee their effectiveness, similar to the primary AST itself.
4. Leak Detection: Certain regulations mandate the use of leak detection systems, allowing for immediate action in the event of a containment breach.
