Ultra-Hard Top Spill Pallets®

Modular IBC Spill Pallets - Outdoor Models

Meet EPA regulations with low-cost outdoor spill containment for multiple IBC tanks

Storing multiple IBCs, totes or tanks outdoors can take up a lot of room, and a lot of money.  But with the Modular IBC Spill Pallets, it can take up less of both.  By connecting the containment sumps and sharing walls, these units offer an economical solution that takes up a relatively small amount of space.

Key Features:
  • Each IBC tank sits on a heavy-duty spill pallet with a capacity of 9,000 lbs UDL.
  • Each of the low profile spill pallets has a containment capacity of 75-gallons and measures 62" x 62" x 8.75”H.
  • Any number of the modular spill pallets can be connected together with bulkhead fittings. Two (2) bulkhead fittings are used to connect one pallet to the next.
  • To increase containment capacity, a 65-gallon capacity Expansion Tank is available. 
  • "Flow-through" bulkhead fittings (1.25-inch diameter) are used to connect spill pallets and Expansion Tanks together.
  • Bulkhead fittings allow spills to be channeled throughout the containment system, thereby "borrowing" containment capacity from adjacent spill pallets and Expansion Tanks.
  • Constructed of 100% polyethylene, eliminating the potential for rust and corrosion. They offer excellent chemical resistance to a broad range of chemicals including acids, solvents, and oils.
  • UV inhibitor in polyethylene resin resists degrading effects of sunlight, adding years to outdoor service life. 
Product Details:
  • Standard offerings include 2-tank, 3-tank, 4-tank and 5-tank models.
  • Connecting an Expansion Tank to a spill pallet also requires two (2) bulkhead fittings.
  • Bulkhead fittings are included with each 2-, 3-, 4-, or 5-tank model.
  • Once five (5) or more spill pallets are connected together, the total containment capacity is 375 gallons minimum and does not require the use of an Expansion Tank to meet the spill containment regulations.
  • Optional Extender Kits (Part# 9658) provide for the addition of another compartment. (1 tank per Extender Kit).
  • Meets SPCC and EPA Container Storage Regulation 40 CFR 264.175.
  • Helps meet Stormwater Management Regulations - NPDES, 40 CFR 122.26 (1999).
  • Considered a "Best Management Practice" (BMP) for providing effective stormwater management.
  • What other stormwater manufacturers won't tell you
  • Protected by the industry’s strongest warranty - Five (5) years against any material or workmanship defects.  Learn more.

Frequently Asked Questions

Why would I get a Modular IBC Spill Pallet instead of one of the other IBC Spill Pallets?
If you have one or two IBCs or you have IBCs in multiple locations around your facility, you wouldn't.  If that were the case, you would use the Ultra-IBC Hard Top or the Ultra-IBC Hard Top Plus.  Where the use of the Modular IBC Spill Pallet, Outdoor Models becomes advantageous is when 3 or more IBCs are kept in the same area.  By connecting the Pallets together along with the Expansion Tanks, the systems will meet the EPA, and SPCC spill containment requirements at a height significantly lower than any other IBC spill pallet on the market.



What's the Expansion Tank for?
The sole purpose of the Expansion Tank is to add containment capacity to the system. Each tank gets connected to the system of spill pallets via bulkhead fittings and adds 65 gallons of containment.



Are the Modular IBCs waterproof?
No, the spill pallet is not completely waterproof.  It is more accurately described as weatherproof.  In other words, in standard weather conditions, your drums and/or containers should be protected and water gathering in the pallets is not a concern.  However, during very gusty conditions or very heavy rainfall, some water may get into the unit.  It is good practice to inspect the interior of the Hard Top after any severe weather.



What size IBCs can be used with the Modular IBC Spill Pallets?
The answer to this question is dependent on the System that is being used and more specifically, the capacity of that System.  A general rule of thumb would be that the largest IBC you could store on the System could not exceed the System's capacity.  Please keep in mind that this rule of thumb would keep you in compliance with the EPA's requirements.  State and local regulations can be more stringent and require more capacity.  Please check with your local authorities to ensure compliance. The inside dimensions of each Hard Top is 62" x 62" x 8.75”H.



Why doesn't the 5-Tank System have any Expansion Tanks included?
The total capacity of the 5-Tank Modular IBC Spill Pallet System is 375 gallons.  Therefore, you would be in compliance with the EPA spill containment regulations assuming that none of your IBCs have a capacity greater than 375 gallons (Go to UltraTech University to learn more about containment capacity requirements)



Can the Ultra-Hard Top Modular Models support an IBC that has pedestal posts for legs, or just flat bottom IBCs? 
The Pallet has a 9,000 lb. capacity.  This is for uniformly distributed loads.  An IBC that is supported by pedestal post or feet focuses all of its weight on those feet.  If the dimensions of those feet are not large enough to properly displace the weight on the Spill Pallet’s grating, it could be an issue.  As a precaution, steel plates (at least 12" x 12") can be used under the feet in order to more evenly distribute the weight over a greater area.  If you have any concerns about your IBCs weight, please contact us at 800-353-1611 / 904-292-1611.
