Spill containment regulations are designed to protect the environment, public health, and workplace safety by preventing the release of hazardous substances into soil, groundwater, and surface water. Whether handling transformer oil, PCBs, or industrial fluids, utility companies and energy providers must comply with multiple regulatory frameworks that govern both storage and transport.
In the United States, the primary authorities overseeing spill containment are the Environmental Protection Agency (EPA) and the Department of Transportation (DOT). Together, their standards form the backbone of responsible environmental management.
This blog explores how these agencies regulate containment systems, what requirements apply to utilities and industrial operations, and how the right products—such as containment bags, liners, and berms—help maintain compliance and protect the environment.
EPA Containment Regulations: Preventing Environmental Contamination
The EPA’s containment requirements focus on stationary facilities—locations where oil, chemicals, or hazardous substances are stored or used. The most relevant federal regulation is the Spill Prevention, Control, and Countermeasure (SPCC) Rule, outlined in 40 CFR Part 112.
Key EPA Requirements
Facilities must install containment systems that can hold at least 110% of the largest container’s volume on-site. This ensures any accidental release or equipment failure is captured before it reaches the environment.
Containment systems must be compatible with the chemicals or oils they’re designed to hold. For instance, Transformer EPA Containment products use chemically resistant materials to prevent oil or dielectric fluid from degrading the containment structure.
The EPA requires regular inspection of containment systems to identify leaks, corrosion, or damage. Consistent maintenance helps prevent equipment failure and ensures long-term reliability.
Facility personnel must be trained to respond quickly to spills, deploy containment solutions, and maintain compliance documentation.
EPA containment systems can include berms, trays, liners, or bags that capture leaks during operation or maintenance. For utilities, Transformer spill containment solutions like flexible containment bags or heavy-duty liners are essential tools for preventing oil leaks at substations or pole-mounted units.
Key DOT Regulations
Ensuring Safe Transport of Hazardous Materials
While the EPA governs stationary containment, the Department of Transportation (DOT) regulates containment during transport. These standards are detailed in 49 CFR Parts 171–180 and are essential for anyone shipping or transferring hazardous materials.
DOT containment requirements protect workers, transporters, and the public by ensuring that packaging and containers can withstand handling, stacking, and environmental conditions during shipment.
Key DOT Requirements
- Packaging and Performance Standards
Containers must be leakproof, durable, and capable of surviving drop, pressure, and vibration tests. DOT hazmat containment bags and Transformer DOT Containment systems are designed specifically for this purpose. - Proper Labeling and Documentation
Every shipment must be clearly labeled with its UN number, hazard class, and handling instructions. Proper documentation ensures traceability and legal compliance. - UN Compliance for Global Transport
When transporting materials across state or international borders, UN-compliant containment bags are required. These bags meet international performance standards and simplify compliance with both domestic and global regulations. - Hazardous Material Transport Containment
For oil-filled transformers, dielectric fluids, or TSCA-regulated materials, using certified hazardous material transport containment products is mandatory. These solutions prevent leaks and maintain containment integrity under real-world transport conditions.

TSCA Compliance: Managing PCB-Contaminated Equipment
In addition to EPA and DOT rules, the Toxic Substances Control Act (TSCA) plays a vital role in regulating hazardous chemicals such as polychlorinated biphenyls (PCBs). PCBs were once widely used in transformers and electrical equipment but are now heavily restricted due to their toxicity and persistence in the environment.
TSCA containment solutions must be used whenever transformers contain or previously contained PCBs. These products are chemically resistant and designed to prevent even trace-level contamination. Compliance under 40 CFR 761 ensures that utilities handle, store, and dispose of PCB-contaminated materials safely and legally.
Failure to comply with TSCA requirements can lead to severe penalties, mandatory cleanup operations, and reputational damage.
Integrated Compliance for Utility Companies
For utility and power distribution companies, maintaining compliance across EPA, DOT, and TSCA regulations requires a layered approach. Each stage of a transformer’s lifecycle—from transport to installation and maintenance—demands specific containment solutions.
Transport Stage
Use Transformer DOT Containment systems or UN-compliant containment bags to protect against leaks while shipping transformers or hazardous equipment.
Operational Stage
Deploy Transformer EPA Containment products like heavy-duty liners, spill bags, or containment berms to capture leaks during daily operation or servicing.
Maintenance and Disposal Stage
Apply TSCA containment solutions when handling or disposing of PCB-containing units to prevent environmental exposure.
Together, these systems form a comprehensive containment strategy that supports environmental protection, regulatory compliance, and operational efficiency.

Why Compliance Matters
Non-compliance with containment regulations can have far-reaching consequences. Environmental damage, legal penalties, and operational disruptions are just a few of the risks. By investing in certified DOT Containment Solutions, EPA Containment Solutions, and utility spill containment products, companies can prevent costly incidents while protecting their communities and ecosystems.
Compliance isn’t just about avoiding fines—it’s a reflection of a company’s commitment to safety, responsibility, and long-term sustainability. Proper containment demonstrates that an organization values its environmental impact and the safety of its workforce.
