When it comes to hazardous material management, containment is not just a best practice—it’s a legal requirement. The Environmental Protection Agency (EPA) enforces strict regulations to prevent hazardous substances like transformer oil, PCBs, and other industrial fluids from contaminating soil, groundwater, and surface water. For utility companies, energy providers, and industrial facilities, understanding these requirements is essential to maintaining safety, compliance, and operational efficiency.
EPA containment standards form the foundation for environmental protection in stationary applications, while the Department of Transportation (DOT) governs containment during transport. Together, these agencies create a regulatory framework that defines how companies must handle, store, and ship hazardous materials.
This guide explores the key EPA requirements for containment, how they relate to DOT standards, and what utilities can do to ensure compliance using proven containment products.
The Purpose of EPA Containment Standards
The EPA’s containment regulations are designed to minimize the risk of environmental pollution from oil and hazardous substance spills. These requirements apply to facilities that store, use, or transfer significant volumes of regulated fluids—such as transformer oils and dielectric fluids used in electrical equipment.
EPA containment solutions are particularly relevant under the Spill Prevention, Control, and Countermeasure (SPCC) Rule, codified in 40 CFR Part 112. This rule mandates that facilities storing more than 1,320 gallons of oil above ground or 42,000 gallons underground must develop and implement an SPCC plan.
The goal is simple: to ensure that any leak, spill, or accidental release is contained before it can reach the environment.
Key EPA Requirements for Containment Systems
EPA containment systems are required to meet several core standards, all of which contribute to preventing contamination and protecting natural resources.
1. Secondary Containment Capacity
The EPA requires secondary containment systems capable of holding at least 110% of the volume of the largest container on-site. This standard ensures that any potential release is captured safely. For utilities, Transformer EPA Containment products such as containment bags, berms, and liners meet this requirement by capturing leaks from pole-mounted or pad-mounted transformers.
2. Structural Integrity and Compatibility
Containment systems must be constructed from materials compatible with the stored fluid. For example, TSCA containment solutions are necessary when handling transformers containing or previously containing PCBs. These materials must be chemically resistant to prevent degradation or seepage over time.
3. Inspection and Maintenance
Facilities are required to conduct routine inspections of all containment structures. Any signs of wear, damage, or fluid accumulation must be addressed immediately. EPA containment solutions are typically designed for durability, UV resistance, and long-term outdoor exposure, ensuring they perform reliably over time.
4. Employee Training
Personnel who work with hazardous materials must receive training on spill response, containment system operation, and inspection procedures. This ensures rapid response and minimizes the risk of environmental exposure in the event of a leak.
Understanding DOT and EPA Rules for Containment Products
While the EPA focuses on stationary containment, the Department of Transportation (DOT) regulates the movement of hazardous materials. These agencies work together to create a comprehensive safety network for hazardous substances across all operational stages.
If you’re looking to understand how both sets of rules interact, visit Understanding DOT And EPA Rules For Containment Products. This resource explains how the two agencies’ requirements overlap and how compliance can be achieved through the use of specialized containment equipment.
During transport, DOT Containment Solutions such as DOT hazmat containment bags, Transformer DOT Containment systems, and UN-compliant containment bags protect against leaks, vibrations, and physical impacts. These products must pass strict performance tests—including drop, leak, and pressure testing—to meet federal and international standards for hazardous material transport containment.
Once transformers or equipment reach their destination, EPA containment solutions take over, providing stationary protection to capture leaks and drips during operation or maintenance.
The Role of TSCA in Transformer Containment
The Toxic Substances Control Act (TSCA) governs the management of hazardous chemicals like polychlorinated biphenyls (PCBs), which were commonly used in older transformers. PCBs are toxic, persistent, and bioaccumulative, meaning they remain in the environment for decades if released.
When transformers contain or have previously contained PCBs, TSCA containment solutions must be used during transport, storage, and maintenance. These solutions ensure fluids are properly contained, preventing cross-contamination and protecting both workers and ecosystems from exposure.
Choosing the Right Utility Spill Containment Products
Selecting the right containment products for utility operations depends on the equipment type, fluid volume, and deployment conditions. Utility spill containment products range from lightweight, portable bags for pole-mounted transformers to large-scale containment berms for substations or storage yards.
Key features to look for include:
- Chemical and UV resistance
- Reinforced seams for added durability
- Foldable or portable designs for rapid deployment
- Compatibility with both DOT and EPA containment regulations
Using the proper containment products helps ensure compliance, reduces cleanup costs, and demonstrates a proactive commitment to environmental protection.

How Containment Solutions Work Together
Comprehensive compliance requires a combination of containment systems that address every stage of a transformer’s lifecycle:
- During Transport: DOT-compliant and UN-compliant containment bags protect against spills while moving equipment between locations.
- During Operation: Transformer EPA Containment systems capture leaks during service and maintenance.
- For Hazardous Fluids: TSCA containment solutions ensure safe handling of PCB-contaminated equipment.
By integrating these systems, utilities can achieve complete regulatory compliance and operational efficiency.

Why Compliance Matters
Compliance with EPA and DOT standards is not only about avoiding penalties—it’s about protecting communities and the environment. Oil and chemical spills can have lasting impacts on ecosystems and public health.
By adopting EPA containment solutions, Transformer DOT Containment systems, and TSCA containment solutions, utilities minimize environmental risks, maintain operational integrity, and strengthen their reputation as responsible industry leaders.
