SPCC Secondary Containment Requirements Explained in 2025

When it comes to preventing oil spills, SPCC secondary containment requirements play a critical role. These regulations, part of the SPCC Rule, aim to stop oil from polluting navigable waters and shorelines. Why does this matter? Spilled oil can poison drinking water, harm wildlife like birds and fish, and destroy vegetation along waterways. For example, between 1980 and 2001, thousands of oil spills occurred annually, causing devastating environmental and economic damage.

Facilities that store oil or oil-related products must comply with these requirements to avoid such disasters. In 2017, a power utility spilled 37,000 gallons of oil into the East River, leading to costly cleanup efforts and environmental harm. By following SPCC regulations, you can protect the environment, avoid penalties, and show your commitment to responsible operations.

Key Takeaways

• Breaking the rules can mean big fines and expensive cleanups. Following SPCC rules saves money and avoids legal problems.

• Training and inspections help your team stay ready. They also make sure your systems work well to stop spills.

• A Professional Engineer can help make a good SPCC plan. Their knowledge ensures your site is safe and follows the law.

What Are SPCC Secondary Containment Requirements?

Definition and Purpose

What is SPCC secondary containment?

SPCC secondary containment refers to specific measures outlined in the SPCC Rule to prevent oil spills from contaminating water sources. These measures include operating procedures, physical barriers, and countermeasures designed to contain oil spills and minimize their impact. Think of it as a safety net for your facility, ensuring that oil stays where it belongs and doesn’t harm the environment.

The Clean Water Act plays a big role here. It mandates these requirements to protect navigable waters and shorelines from oil pollution. By implementing SPCC secondary containment, you’re not just following regulations—you’re actively safeguarding water quality and ecosystems.

Why is it required under the SPCC Rule?

The SPCC Rule exists to prevent oil spills from reaching navigable waters. Secondary containment is a critical part of this rule because it provides a backup plan if primary containment (like a tank or pipe) fails. Without these measures, oil spills could spread quickly, causing significant environmental damage. Facilities with SPCC plans have seen fewer spills, reduced spill volumes, and lower cleanup costs compared to those without such plans. These benefits highlight why secondary containment is essential for compliance and environmental protection.

Applicability to Facilities

Types of facilities that must comply

Not every facility needs to follow SPCC secondary containment requirements, but many do. If your facility stores oil or oil-related products, you’re likely on the list. This includes power plants, manufacturing facilities, farms, and even some transportation hubs. The key is whether your operations could reasonably discharge oil into navigable waters or shorelines.

Thresholds for oil storage capacity

The SPCC Rule applies to facilities with an oil storage capacity of more than 1,320 gallons in aboveground containers or more than 42,000 gallons in underground containers. If your facility meets these thresholds, you must comply with SPCC regulations. It’s crucial to assess your storage capacity and ensure you’re meeting the requirements to avoid penalties and protect the environment.

Why Are SPCC Secondary Containment Requirements Important for Compliance?

Environmental Protection

Preventing contamination of water sources

Oil spills can wreak havoc on water sources, making them unsafe for drinking, agriculture, and recreation. By following SPCC secondary containment requirements, you can prevent oil from seeping into rivers, lakes, and groundwater. These measures act as a barrier, stopping spills before they spread. Imagine the impact of a single spill contaminating a community’s water supply—it’s not just an environmental issue but a public health crisis. With proper spill prevention strategies, you’re taking a proactive step to protect vital water resources.

Reducing harm to ecosystems and wildlife

Oil spills don’t just affect water; they devastate ecosystems. Birds, fish, and other wildlife often suffer the most. Oil coats their bodies, disrupts their habitats, and can even lead to death. By implementing SPCC measures, you’re helping to safeguard these ecosystems. Think of it as doing your part to preserve biodiversity and maintain the balance of nature.

Legal and Financial Risks of Non-Compliance

Fines and penalties for violations

Non-compliance with SPCC regulations can cost you—big time. The EPA imposes fines that range from minor amounts to millions of dollars, depending on the severity of the violation. For example:

• Facilities can face fines exceeding $32,000 per day for non-compliance.

• A failure to review or amend an SPCC plan could result in a $1,500 fine, even without a spill.

• In one case, a facility was fined $44,000 for not having a spill control plan and spilling oil into navigable waters.

These penalties add up quickly, especially for repeat offenders. Avoiding them starts with meeting the requirements.

Costs of cleanup and remediation

The financial burden doesn’t stop at fines. Cleanup costs after a spill can be astronomical. Facilities may also face lawsuits from affected communities or businesses. By adhering to SPCC requirements, you minimize these risks and save money in the long run.

Corporate Responsibility and Reputation

Building trust with stakeholders

Your commitment to SPCC compliance sends a strong message to stakeholders. It shows you care about the environment and take your responsibilities seriously. Companies with effective SPCC measures often enjoy better relationships with customers, investors, and local communities. Trust is hard to earn but easy to lose—don’t let non-compliance tarnish your reputation.

Avoiding negative publicity

No one wants to see their company’s name in headlines for the wrong reasons. A single oil spill can lead to years of reputational damage. On the flip side, demonstrating environmental responsibility can attract eco-conscious consumers and investors. It’s not just about avoiding bad press; it’s about building a positive image that lasts.

Types of SPCC Secondary Containment Systems

Specific (Sized) Secondary Containment

Definition and requirements

Specific secondary containment systems are designed to handle the largest potential spill from a single container or interconnected containers. These systems must meet SPCC secondary containment requirements by being large enough to contain the entire volume of the largest container, plus additional capacity for precipitation. This ensures that even in the worst-case scenario, oil stays contained and doesn’t harm the environment.

Examples

You’ll find several examples of specific containment systems in industrial settings:

• Double-walled tanks: These are commonly used for aboveground oil storage and provide an extra layer of protection.

• Diking or curbing: Facilities often use impervious concrete to create barriers around drum and tote storage areas.

• Blind sumps or trenching: These are installed in storage and transfer areas to capture spills effectively.

• Spill pallets: These are ideal for drum or tote storage, offering a portable containment solution.

• Oil-water separators: These systems are sized to handle the largest container and precipitation flow, ensuring compliance.

A real-world example highlights the importance of proper sizing. In 1988, Ashland Petroleum faced a disaster when a diesel tank collapsed, spilling 3.8 million gallons. Their containment system could only hold 2.5 million gallons, leading to severe environmental damage and cleanup costs exceeding $18 million. This case underscores why proper design and capacity are critical.

General Secondary Containment

Definition and requirements

General secondary containment focuses on preventing oil from reaching navigable waters during smaller spills or leaks. Unlike specific systems, these don’t require sizing for the largest container but must still be effective in containing oil. They’re often used as a backup to primary containment systems.

Examples

Here are some common general containment solutions:

• Spill kits: These portable kits include absorbent materials and tools to quickly address small spills.

• Drainage systems: Facilities use these to direct spills into containment areas, preventing oil from spreading.

Comparative studies show that liner systems play a significant role in general containment. For example:

Investing in durable materials and proper construction ensures these systems perform effectively over time.

Design Considerations for Compliance

Capacity and material compatibility

When designing containment systems, you need to consider capacity and material compatibility. The system must hold the largest container’s volume and account for precipitation. Materials like concrete can degrade over time due to exposure to oil and weather, so alternatives like high-grade stainless steel or specialized alloys may be better options. Regular monitoring and maintenance also help maintain system integrity.

Handling precipitation and storm events

SPCC regulations emphasize the importance of handling stormwater. Your containment system should include sufficient freeboard to manage heavy rainfall. This ensures compliance and prevents overflow during extreme weather. Adding monitoring technologies can help you stay ahead of potential issues, making your system more reliable and efficient.

How to Ensure Compliance with SPCC Secondary Containment Requirements
