EPA SPCC: Secondary Containment & Environmental Safety Guide
The Environmental Protection Agency’s (EPA) Spill Prevention, Control, and Countermeasure (SPCC) Rule is a cornerstone of environmental safety for facilities that store oil and related products. Established under the Clean Water Act, the SPCC Rule is designed to prevent oil discharges into navigable waters and adjoining shorelines, safeguarding both the environment and public health.
Facilities that store more than 1,320 gallons of oil above ground or 42,000 gallons underground are required to develop and implement a comprehensive SPCC Plan. The SPCC Plan is a detailed, facility-specific protocol outlining how a business will prevent, control, and respond to oil spills. This plan must address all relevant spill prevention, control, and countermeasures necessary at the specific facility, and it must be reviewed and updated regularly to ensure ongoing compliance and effectiveness.
The Importance of Secondary Containment
One of the most critical components of the SPCC Rule is the requirement for secondary containment. Secondary containment refers to structures or equipment designed to catch spills or leaks from primary storage containers, preventing oil from reaching the environment. The EPA recognizes that even the best-designed primary containers can fail, making secondary containment a vital line of defense.
Secondary containment systems are required for bulk storage containers, transfer areas, and oil-filled equipment. The goal is to provide temporary containment of discharged oil until response and cleanup can occur, minimizing the risk of environmental contamination and costly remediation efforts.
By implementing effective secondary containment, facilities can avoid reportable discharges and potential fines, while demonstrating a commitment to environmental stewardship.

Key Requirements for Secondary Containment
The EPA’s SPCC Rule outlines both general and specific secondary containment requirements:
- General Secondary Containment: Applies to the most likely oil discharge scenarios from containers, piping, and equipment. The system must capture the volume of oil expected during a spill, using good engineering practices.
- Specific Secondary Containment: For bulk storage containers, containment must hold the full capacity of the largest tank plus sufficient freeboard to account for precipitation. The EPA recommends freeboard to contain a 25-year, 24-hour storm event, though standards may vary by facility design.
Facilities have flexibility in meeting these requirements. Options include dikes, berms, double-walled tanks, spill pallets, and drainage systems. The chosen method must suit operations and prevent oil escape.
Environmental Safety and Compliance
Environmental safety is at the heart of the SPCC Rule. By requiring secondary containment, the EPA aims to prevent oil spills from polluting waterways, harming wildlife, and impacting communities. Compliance not only protects the environment but also shields businesses from financial and reputational risks.
Facilities must maintain inspection and test records for their containment systems to ensure functionality. Regular spill prevention and response training for employees fosters a culture of safety and preparedness.
The Role of Storage Tanks and Pressure Vessels
For fabricators and manufacturers of stainless steel storage tanks and pressure vessels, understanding and adhering to SPCC requirements is crucial. Storage tanks are primary containers for oil, making them central to containment planning. Pressure vessels that store or process oil under pressure also require robust containment to manage leak or rupture risks.
Properly designed tanks and vessels meet strength and durability standards and facilitate SPCC compliance. Features like integrated containment, leak detection, and corrosion-resistant materials enhance safety and regulatory adherence.
Best Practices for SPCC Secondary Containment
Effective SPCC compliance hinges on well-designed and maintained secondary containment systems. Following best practices helps prevent environmental contamination and ensures facilities meet regulatory requirements for safe storage tank operations.
- Conduct Regular Inspections: Routine checks of tanks, vessels, and containment systems help catch issues before spills occur.
- Maintain Accurate Records: Document inspections, maintenance, and repairs to demonstrate compliance and support incident investigations.
- Train Employees: Provide ongoing training on SPCC requirements, spill response procedures, and environmental protection.
- Plan for Storm Events: Design containment with adequate freeboard for heavy rainfall to prevent overflow.
- Engage Qualified Professionals: Work with experienced engineers and fabricators to design, install, and maintain compliant solutions.
