The Environmental Protection Agency (EPA) creates and enforces regulations that protect both human health and the environment. One critical area under its jurisdiction is secondary containment systems, which reduce the risk of putting harmful substances into the environment during spills or leaks. These systems act as a safeguard, providing an added layer of protection to prevent contaminating the environment. These EPA requirements for secondary containment systems are important, and for your industry, following them is a must.

Identify Applicable Regulations

The EPA has established specific regulations for secondary containment systems, but these rules are not one-size-fits-all. They vary based on the type of hazardous substance being stored or handled, as well as the facility’s operations. For example, certain regulations under the Clean Water Act or the Resource Conservation and Recovery Act (RCRA) may apply to your facility, depending on the type and quantity of hazardous materials involved. Thoroughly review EPA guidelines and identify which regulations are relevant to your situation.

Determine the Level of Containment Required

Secondary containment requirements come from factors such as the volume, properties, and classification of hazardous substances in use. The EPA categorizes hazardous materials into specific groups, with each group having unique containment needs. For instance, flammable or corrosive chemicals need a higher level of containment compared to less volatile substances.

Facilities must accurately assess their inventory and calculate the total volume of hazardous materials to determine the appropriate containment capacity. These assessments should be detailed and account for worst-case scenarios to ensure compliance and protect against potential risks.

Choose Suitable Materials

The effectiveness of a secondary containment system directly correlates to the materials used in its construction. The EPA requires that containment materials be compatible with the hazardous substances being stored to prevent degradation or chemical reactions that could compromise the system’s integrity. For example, substances like acids may require containment systems made from materials resistant to corrosion, such as polyethylene or coated steel. The proper material selection extends the lifespan of the containment system and reduces the risk of leaks.

Train Employees on Proper Handling Procedures

Employees who work with hazardous substances play a critical role in maintaining compliance and ensuring workplace safety. The EPA requires that all personnel receive thorough training on the proper handling, storage, and disposal of hazardous materials. This training should also cover the use of secondary containment systems, including protocols for inspecting and maintaining them, as well as steps to take in the event of a spill or leak.

EPA requirements for secondary containment systems are a cornerstone of environmental safety and regulatory compliance. These systems are essential for preventing hazardous substances from contaminating the air, water, and soil.
