Are There Regulatory Requirements for Using Steel Storage Tanks?

Steel storage tanks play a critical role in various industries, from oil and gas to agriculture, offering a reliable solution for storing liquids, chemicals, and fuels.

However, the use of these tanks, particularly when used for storing hazardous materials, is subject to stringent regulatory requirements to ensure safety and environmental protection.

This blog explores the regulatory landscape surrounding steel storage tanks, with a focus on underground storage tanks (USTs), and provides an overview of key compliance aspects.

Understanding Steel Storage Tanks

Steel storage tanks are designed to withstand harsh conditions and are typically used for storing large quantities of liquids. They come in various shapes and sizes, including above-ground and underground installations. Steel tanks are favored for their durability and strength, making them suitable for storing substances like petroleum, chemicals, and water.

The Need for Regulation

Stringent regulations are necessary to mitigate the potential risks associated with the storage of hazardous substances. Leaks or spills from steel storage tanks can have severe environmental and health consequences. Regulatory frameworks enforce standards for storage tank design, installation, operation, and maintenance to mitigate these risks.

Regulatory Bodies and Frameworks

In many countries, different regulatory bodies oversee the use of steel storage tanks. For example:

• United States: The Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA) are key regulatory agencies. The EPA focuses on environmental protection, while OSHA addresses workplace safety.
• European Union: The European Chemicals Agency (ECHA) and various national agencies manage regulations related to chemical storage.
• Australia: The Australian Government Department of Agriculture, Water, and the Environment, along with local state authorities, enforces regulations related to tank storage.

Key Regulatory Requirements for Steel Storage Tanks

Design and Construction

Steel storage tanks must be designed and constructed to meet specific standards that ensure their ability to safely contain their contents. This includes:

• Material Standards: Tanks must be constructed from materials that resist corrosion and degradation. Steel tanks are often coated or lined to prevent rust and leakage.
• Structural Integrity: The design must accommodate the weight and pressure of the stored liquid, as well as withstand environmental factors like seismic activity or extreme weather conditions.
• Secondary Containment: For tanks storing hazardous substances, secondary containment systems (such as double-walled tanks or berms) are required to catch any leaks or spills.

Installation

Proper installation is critical to the safe operation of steel storage tanks. Regulatory requirements often include:

• Site Assessment: The location must be assessed for potential risks, including proximity to water sources, groundwater, and populated areas.
• Installation Procedures: Installation must follow specific procedures to ensure that tanks are securely anchored and that any potential leak paths are sealed.
• Inspections and Testing: Before being put into service, tanks must undergo thorough inspections and testing to ensure they meet all safety and regulatory standards.

Operation and Maintenance

Ongoing operation and maintenance are crucial for preventing leaks and ensuring the safe use of steel storage tanks. Regulations typically cover:

• Routine Inspections: Regular inspections are required to check for signs of wear, corrosion, or damage. These inspections help identify potential issues before they become serious problems.
• Leak Detection: Monitoring systems may be required to detect leaks promptly. This could include visual inspections and automated systems that alert operators to potential issues.
• Record Keeping: Detailed records of inspections, maintenance, and any repairs or modifications must be kept. These records are important for demonstrating compliance with regulations and for troubleshooting any issues that arise.

Decommissioning and Disposal

When a steel storage tank reaches the end of its useful life, proper decommissioning and disposal are essential:

• Emptying and Cleaning: Tanks must be thoroughly emptied and cleaned to remove any residual substances before being removed from service.
• Environmental Considerations: The decommissioning process must consider potential environmental impacts. To prevent contamination, hazardous materials must be disposed of according to regulations.
• Documentation: Records of the decommissioning process, including any environmental assessments and disposal methods, must be maintained.

Underground Storage Tanks (USTs)

Underground storage tanks present unique challenges and regulatory requirements due to their hidden nature and potential risk of leaks into the surrounding soil and groundwater. Key considerations for USTs include:

Installation and Location

• Site Assessments: The installation site for USTs must be carefully assessed to identify any potential risks, such as proximity to groundwater or sensitive ecosystems.
• Tank Construction: USTs must be constructed from materials that resist corrosion and potential leakage. Many regulations require tanks to have double-walled construction or corrosion protection measures.
• Permitting: Installation of USTs typically requires permits and adherence to local, state, and federal regulations.

Monitoring and Testing

• Leak Detection Systems: USTs must be equipped with leak detection systems to monitor for any signs of leakage. These systems may include sensors, alarms, and periodic testing procedures.
• Routine Monitoring: Regular monitoring and maintenance are required to ensure the integrity of USTs. This includes checking for signs of corrosion, leaks, or other issues.

Compliance and Reporting

• Regulatory Compliance: Operators must comply with all relevant regulations, including those related to USTs. This may involve regular reporting to regulatory agencies and adherence to specific operational standards.
• Emergency Response: Procedures must be in place for responding to leaks or spills. This includes having a plan for containment and remediation and notifying regulatory agencies if an incident occurs.

Best Practices for Compliance

To ensure compliance with regulatory requirements for steel storage tanks, consider the following best practices:

• Stay Informed: Regularly review and stay updated on regulations and standards relevant to steel storage tanks and USTs. Regulatory requirements can change, and staying informed helps ensure ongoing compliance.
• Work with Experts: Consult with industry experts, including engineers, environmental consultants, and regulatory advisors, to ensure that your tanks are designed, installed, and maintained according to best practices and regulatory standards.
• Training and Education: Ensure that staff responsible for the operation and maintenance of steel storage tanks receive appropriate training. This includes understanding regulatory requirements and best practices for tank management.
• Implement Robust Systems: Invest in reliable monitoring and leak detection systems to proactively manage potential issues. Regular maintenance and prompt repairs are crucial for preventing leaks and ensuring the safe operation of storage tanks.

Conclusion

Steel storage tanks, including underground storage tanks, are essential components in many industries, but their use is subject to strict regulatory requirements to protect human health and the environment. Understanding and adhering to these regulations is crucial for ensuring the safe and responsible management of storage tanks.

By focusing on proper design, installation, operation, and maintenance and staying informed about regulatory changes, businesses can effectively manage their steel storage tanks and contribute to environmental protection and safety.
