Primary Containment

First off, you may be asking what Primary Containment is. It is a tank, vessel, pipe, transport vessel or equipment intended to serve as the primary container for, or used for the transfer of material. Primary containers may be designed with secondary containment systems to contain or control a release from the primary containment. Secondary containment systems include, but are not limited to, tank dikes, curbing around process equipment, drainage collection systems into segregated oily drain systems, the outer wall of double-walled tanks, etc.

Spill Containment vs Secondary Containment



If you don't have secondary containment, you need spill containment. If you do have secondary containment, you still need spill containment. Read on to understand the role of each type of containment and why you should have both. 

Spill Containment

The act of stopping a spill is spill containment. When there's a spill, your priority — after addressing safety issues — is to stop it from spreading. The sooner you contain a spill, the smaller the area that is affected. And that means it will take less time to clean up the spill.
The thing to remember is that spill containment is part of spill response. Spill response plans often contain different types of spill containment to address different types of spills, including absorbent socks and booms, non-absorbent dikes or even drainage sumps designed to collect spilled liquids. For example, spill containment for a five-gallon oil spill in a warehouse with no floor drains might call for a few socks and absorbent mats. Still, spill containment for a 30,000-gallon fuel spill heading toward a nearby river is going to take a full arsenal of booms, absorbents, and sumps to control.


SPCC Secondary Containment


Secondary Containment

Drums, totes, and tanks are examples of primary containers. These containers usually keep their liquid contents in check without incident. But if they contain a hazardous substance, and because they can fail, the EPA requires them to have secondary containment.
The EPA doesn't specify exactly what secondary containment must look like. Still, they are clear about what it needs to do: If the primary container fails, the secondary containment structure or device must be able to hold the entire volume that could spill until it can be cleaned up.
That means that secondary containment can be anything from spill pallets or decks to a sloped room that allows the liquid to accumulate at one end until it can be cleaned up. It could be dikes, berms or concrete walls that create a moat around the primary container. In some cases it can even be absorbents. It's up to you to evaluate your situation and determine the best solutions for your needs.

Why You Should Have Both

Even super-sturdy secondary containment systems can fail and cause a spill, so the EPA expects you to be prepared for spills with appropriate spill containment — even if every container at your facility has secondary containment. That's why, when people ask if they need spill containment or secondary containment, our answer is always, "BOTH!"
What People Get Confused About Secondary Containment

What People Get Confused About Secondary Containment


What are the specific requirements for secondary containment of oil containers at SPCC-regulated facilities?

The entire containment system, including the walls and floor, should be capable of consisting of oil and must be built so that any discharge from a primary containment system, such as a tank or pipe, will not leave the containment system before clean-up occurs (40 CFR 112.7( c)).

Exceptions apply to certified oil-filled functional devices and flowlines and intrafacility event lines at oil production facilities.

Here's more on simplifying secondary containment requirements.

Owners and operators of facilities based on SPCC requirements should provide secondary containment for their bulk storage container setups (other than mobile refuelers and other non-transportation-related tank trucks) that are capable of holding the contents of the biggest single container plus adequate freeboard to contain rainfall (40 CFR 112.8( c)( 2 )). What does EPA consider sufficient freeboard?

A 25-year, 24-hour storm event requirement is a proper requirement of enough freeboard for a lot of centers. Nevertheless, EPA did not promulgate this requirement because of the trouble and cost for some facilities to get this storm occasion information.

EPA's SPCC guideline affects over 630,000 centers. Is yours one? Download your EHS Essentials Kit-- SPCC Plan Compliance now for all the tools you need to be in compliance. Download Now

Does EPA have a main choice contingency plan or secondary containment for SPCC Planning purposes?

EPA does not think that a contingency plan is a more effective option to secondary containment. EPA's position is that secondary containment is preferable due to the fact that it might prevent a discharge that may be hazardous. A contingency plan is a plan for action when the discharge has actually already happened. However, if secondary containment is not practicable, the owner or operator need to supply a contingency strategy and take other actions as needed.

Must owners or operators of facilities subject to SPCC requirements supply secondary containment, as required by Section 112.8( c)( 2 ), for oil-filled devices, such as transformers?

Owners or operators need to supply secondary containment for all bulk storage container setups, except mobile refuelers and other non-transportation-related tank trucks. Oil-filled electrical equipment is particularly excluded from the definition of "bulk storage container."

Thus, the secondary containment requirements of 40 CFR 112.8( c)( 2) are not suitable to oilfilled electrical equipment, such as transformers.

What are the secondary containment requirements for single-compartment and manifolded tanks?

The SPCC requirement for secondary containment requirements associates with the capacity of the biggest single compartment or container. Permanently manifolded tanks are tanks that are developed, set up, or operated so that the several containers operate as a single storage unit. Containers that are permanently manifolded together might count as the "largest single compartment."

If you do not have secondary containment, you need spill containment. If you do have secondary containment, you still need spill containment. Continue reading to comprehend the function of each sort of containment and also why you ought to have both.

The act of preventing a spill is spill containment. When there's a spill, your very first top priority-- after dealing with safety concerns-- is to stop it from spreading. The quicker you contain a spill, the smaller the area that is impacted. Which means it will take much less time to clean up the spill.

The thing to keep in mind is that spill containment becomes part of spill reaction. Spill action plans commonly contain different kinds of spill containment to attend to different types of spills, including absorptive socks as well as booms, non-absorbent dikes or even drain sumps created to collect splashed fluids. For instance, spill containment for a five-gallon oil spill in a storage facility without any floor drains pipes could ask for a few socks and absorptive floor coverings, yet spill containment for a 30,000-gallon fuel spill heading towards a nearby river is mosting likely to take a full collection of booms, absorbents and sumps to control.

Secondary Containment
Drums, totes and tanks are examples of primary containers. These containers typically maintain their fluid materials in check without incident. But if they contain an unsafe material, and also due to the fact that they can fall short, the EPA requires them to have secondary containment.

The EPA does not define exactly what secondary containment must resemble, however they are clear concerning what it requires to do: If the primary container falls short, the secondary containment structure or device have to be able to hold the entire quantity that can spill till it can be tidied up.

That means that secondary containment can be anything from spill pallets or decks to a sloped room that permits the fluid to accumulate at one end till it can be tidied up. It could be dikes, berms or concrete walls that develop a moat around the primary container. In many cases it can even be absorbents. It's up to you to assess your circumstance as well as choose the most effective services for your demands.

Why You Should Have Both
Even super-sturdy secondary containment systems can stop working and also create a spill, so the EPA needs you to be prepared for spills with ideal spill containment-- even if every container at your facility has secondary containment. That's why, when individuals ask us if they need spill containment or secondary containment, our solution is constantly, yes!
